This package groups all the classes and functions exported by the GNAT Programming System.
These functions are made available through various programming languages (Python and the GPS shell at the moment). The documentation in this package is mostly oriented towards Python, but can also be used as a reference for the GPS shell.
For all functions, the list of parameters is specified. The first parameter is often called “self”, and refers to the instance of the class to which the method applies. In Python, the parameter is generally put before the method’s name, as in:
self.method(arg1, arg2)
Although it could also be called as in:
method(self, arg1, arg2)
For all other parameters, their name and type are specified. An additional default value is given when the parameter is optional. If no default value is specified, the parameter is mandatory and should always be specified. The name of the parameter is relevant if you chose to use Python’s named parameters feature, as in:
self.method(arg1="value1", arg2="value2")
which makes the call slightly more readable. The method above would be defined with three parameters in this documentation (resp. “self”, “arg1” and “arg2”).
Some examples are also provides for several functions, to help clarify the use of the function.
A very useful feature of Python is that all class instances can be associated with any number of user data fields. For example, if you create an instance of the class GPS.EditorBuffer, you can associate two fields “field1” and “field2” to it (the names and number are purely for demonstration purposes, and you can use your own), as in:
ed = GPS.EditorBuffer.get(GPS.File("a.adb"))
ed.field1 = "value1"
ed.field2 = 2
GPS takes great care for most classes to always return the same Python instance for a given GUI object. For example, if you were to get another instance of GPS.EditorBuffer for the same file as above, you would receive the same Python instance and thus the two fields are available to you, as in:
ed = GPS.EditorBuffer.get(GPS.File("a.adb"))
# ed.field1 is still "value1"
This is a very convenient way to store your own data associated with the various objects exported by GPS. These data cease to exist when the GPS object itself is destroyed (for instance when the editor is closed in the example above).
In many cases, you need to connect to specific hooks exported by GPS to be aware of events happening in GPS (such as the loading of a file or closing a file). These hooks and their use are described in the GPS manual (see also the GPS.Hook class).
Here is a small example, where the function on_gps_started() is called when the GPS window is fully visible to the user:
import GPS
def on_gps_started(hook):
pass
GPS.Hook("gps_started").add(on_gps_started)
The list of parameters for the hooks is described for each hook below. The first parameter is always the name of the hook, so that the same function can be used for multiple hooks if necessary.
There are two categories of hooks: the standard hooks and the action hooks. The former return nothing, the latter return a boolean indicating whether your callback was able to perform the requested action. They are used to override some of GPS’s internal behavior.
Adds a command to the navigation buttons in the toolbar. When the user presses the Back button, this command is executed and puts GPS in a previous state. This is, for example, used while navigating in the HTML browsers to handle their Back button.
Parameters: | command – A string |
---|
Returns the base name for the given full path name.
Parameters: | filename – A string |
---|
Changes the current directory to dir.
Parameters: | dir – A string |
---|
Updates the cross-reference information stored in GPS. This needs to be called after major changes to the sources only, since GPS itself is able to work with partially up-to-date information
Returns the context at the time the contextual menu was open.
This function only returns a valid context while the menu is open or while an action executed from that menu is being executed. You can store your own data in the returned instance so that, for example, you can precompute some internal data in the filters for the contextual actions (see <filter> in the XML files) and reuse that precomputed data when the menu is executed. See also the documentation for the “contextual_menu_open” hook.
Returns: | An instance of e.g., GPS.FileContext or GPS.AreaContext |

Returns the current context in GPS. This is the currently selected file, line, column, project, etc. depending on what window is currently active. From one call of this function to the next, a different instance is returned, so you should not store your own data in the instance, since you will not be able to recover it later on
Returns: | An instance of, e.g., GPS.FileContext or GPS.AreaContext |
---|
See also
GPS.MDI.current:() Access the current window
Deletes the file or directory name from the file system.
Parameters: | name – A string |
---|
Lists files matching pattern (all files by default).
Parameters: | pattern – A string |
---|---|
Returns: | A list of strings |
Returns the directory name for the given full path name.
Parameters: | filename – A string |
---|
Dumps string to a temporary file. Return the name of the file. If add_lf is True, appends a line feed at end of the name.
Parameters: |
|
---|---|
Returns: | A string, the name of the output file |
Writes text to the file specified by filename. This is mostly intended for poor shells like the GPS shell which do not have better solutions. In Python, you should use its own mechanisms.
Parameters: |
|
---|
This function is specific to Python. It executes the string given in argument in the context of the GPS Python console. If you use the standard Python exec() function instead, it only modifies the current context, which generally has no impact on the GPS console itself.
Parameters: | noname – A string |
---|
# Import a new module transparently in the console, so that users can
# immediately use it
GPS.exec_in_console("import time")
Executes one of the actions defined in GPS. Such actions are either predefined by GPS or defined by the users through customization files. See the GPS documentation for more information on how to create new actions. GPS waits until the command completes to return control to the caller, whether you execute a shell command or an external process.
The action’s name can start with a ‘/’, and be a full menu path. As a result, the menu itself will be executed, just as if the user had pressed it.
The extra arguments must be strings, and are passed to the action, which can use them through $1, $2, etc.
The list of existing actions can be found using the Edit ‣ Actions menu.
The action is not executed if the current context is not appropriate for it
Parameters: |
|
---|
See also
GPS.execute_action(action="Split vertically")
# will split the current window vertically
Like GPS.execute_action(), but commands that execute external applications or menus are executed asynchronously: this function immediately returns even though external application may not have completed its execution.
Parameters: |
|
---|
See also
Exits GPS, asking for confirmation if any file is currently modified and unsaved. If force is True, no check is done.
status is the exit status to return to the calling shell. 0 means success on most systems.
Parameters: |
|
---|
Prevents the signal “preferences_changed” from being emitted. Call thaw_prefs() to unfreeze.
Freezing/thawing this signal is useful when you are about to modify a large number of preferences in one batch.

Forces GPS to use the cross-reference information it already has in memory. GPS no longer checks on the disk whether more recent information is available. This can provide a significant speedup in complex scripts or scripts that need to analyze the cross-reference information for lots of files. In such cases, the script should generally call GPS.Project.update_xref() to first load all the required information in memory.
You need to explicitly call GPS.thaw_xref() to return to the default GPS behavior. Note the use of the “finally” exception handling in the following example, which ensures that even if there is some unexpected exception, the script always restores properly the default behavior.
try:
GPS.Project.root().update_xref(recursive=True)
GPS.freeze_xref()
... complex computation
finally:
GPS.thaw_xref()
Returns the name of the current build mode. Returns an empty string if no mode is registered.
Returns the result of the last compilation command.
Parameters: |
|
---|---|
Returns: | A string or list, the output of the latest build for the corresponding target |
Returns the directory that contains the user-specific files. This string always ends with a directory separator.
Returns: | The user’s GPS directory |
---|

log = GPS.get_home_dir() + "log"
# will compute the name of the log file generated by GPS
Returns the installation directory for GPS. This string always ends with a directory separator.
Returns: | The install directory for GPS |
---|
See also
html = GPS.get_system_dir() + "share/doc/gps/html/gps.html"
# will compute the location of GPS's documentation
Returns the directory where gps creates temporary files. This string always ends with a directory separator.
Returns: | The install directory for GPS |

Indicates where the server is the local machine.
Parameters: | server – The server. Possible values are “Build_Server”, “Debug_Server”, “Execution_Server” and “Tools_Server” |
---|---|
Returns: | A boolean |
Returns the name of the last action executed by GPS. This name is not ultra-precise: it is accurate only when the action is executed through a key binding. Otherwise, an empty string is returned. However, the intent is for a command to be able to check whether it is called multiple times consecutively. For this reason, this function returns the command set by GPS.set_last_command(), if any.
Returns: | A string |
---|
See also
def kill_line():
'''Emulates Emacs behavior: when called multiple times, the cut line
must be appended to the previously cut one.'''
# The name of the command below is unknown to GPS. This is just a
# string we use in this implementation to detect multiple
# consecutive calls to this function. Note that this works whether
# the function is called from the same key binding or not and from
# the same GPS action or not
append = GPS.last_command() == "my-kill-line":
GPS.set_last_command("my-kill-line")
Returns the list of all known GPS actions, not including menu names. All actions are lower-cased, but the order of the list is not significant.
Returns: | A list of strings |
---|
See also
Given a key binding, for example “control-x control-b”, returns the list of actions that could be executed. Not all actions would be executed, however, since only the ones for which the filter matches are executed. The names of the actions are always in lower case.
Parameters: | key – A string |
---|---|
Returns: | A list of strings |
See also
Lists the files matching pattern (all files by default).
Parameters: | pattern – A string |
---|---|
Returns: | A list of strings |
Returns the list of modules currently registered in GPS. Each facility in GPS is provided in a separate module so that users can choose whether to activate specific modules or not. Some modules can also be dynamically loaded.
Returns: | List of strings |
---|

Loads an XML customization string. This string should contain one or more toplevel tags similar to what is normally found in custom files, such as <key>, <alias>, <action>.
Optionally you can also pass the full contents of an XML file, starting with the <?xml?> header.
Parameters: | xml – The XML string to parse |
---|
GPS.parse_xml(
'''<action name="A"><shell>my_action</shell></action>
<menu action="A"><title>/Edit/A</title></menu>''')
Adds a new menu in GPS, which executes the command my_action
Prints name of the current (working) directory.
Returns: | A string |
---|
This function has the same return value as the standard Python function os.getcwd(). The current directory can also be changed through a call to os.chdir(“dir”).
Executes the next action count times.
Parameters: | count – An integer |
---|
Empties the internal xref database for GPS. This is rarely useful, unless you want to force GPS to reload everything.
Forces an immediate save of the persistent properties that GPS maintains for files and projects (for example the text encoding, the programming language, and the debugger breakpoints).
This is done automatically by GPS on exit, so you normally do not have to call this subprogram.
Sets the current build mode. If mode is not a registered mode, does nothing.
Parameters: | mode – Name of the mode to set |
---|
Overrides the name of the last command executed by GPS. This new name is the one returned by GPS.last_command() until the user performs a different action. Thus, multiple consecutive calls of the same action always return the value of the command parameter. See the example in GPS.last_command().
Parameters: | command – A string |
---|
See also
Returns the list of languages for which GPS has special handling. Any file can be opened in GPS, but some extensions are recognized specially by GPS to provide syntax highlighting, cross-references, or other special handling. See the GPS documentation on how to add support for new languages in GPS.
The returned list is sorted alphabetically and the name of the language has been normalized (starts with an upper case character and is lowercase for the rest except after an underscore character).
Returns: | List of strings |
---|
GPS.supported_languages()[0]
=> return the name of the first supported language
Re-enables calling the “preferences_changed” hook.
See also
See GPS.freeze_xref() for more information.
See also
Returns the GPS version as a string.
Returns: | A string |
---|
Returns the location of the xref database. This is an sqlite database created by GPS when it parses the .ali files generated by the compiler. Its location depends on both the location of the root project (the database is in its object directory by default), and its optional IDE’Xref_Database attribute, which can be used to specify an alternate location.
Returns: | a string |
---|
Return true if the xref database is frozen.

This class gives access to the interactive commands in GPS. These are the commands to which the user can bind a key shortcut or for which we can create a menu. Another way to manipulate those commands is through the XML tag <action>, but it might be more convenient to use Python since you do not have to qualify the function name.

Creates a new instance of Action. This is bound with either an existing action or with an action that will be created through GPS.Action.create(). The name of the action can either be a simple name, or a path name to reference a menu, such as /Edit/Copy.
Parameters: | name – A string |
---|
Create a new contextual menu associated with the command. This function is somewhat of a duplicate of GPS.Contextual.create(), but with one major difference: the callback for the action is a Python function that takes no argument while the callback for GPS.Contextual() receives one argument.
Parameters: |
|
---|
Export the function on_activate() and make it interactive so that users can bind keys and menus to it. The function should not require any argument, since it will be called with none.
The package gps_utils.py provides a somewhat more convenient Python interface to make functions interactive (see gps_utils.interactive).
Parameters: |
|
---|
Execute the action if its filter matches the current context. If it could be executed, True is returned, otherwise False is returned.
Returns: | A boolean |
---|
Associate a default key binding with the action. This is ignored if the user defined his own key binding. You can experiment with possible values for keys by using the /Edit/Key Shortcuts dialog.
Parameters: | key – A string |
---|
Create a new menu associated with the command. This function is somewhat a duplicate of GPS.Menu.create(), but with one major difference: the callback for the action is a python function that takes no argument, whereas the callback for GPS.Menu() receives one argument.
Parameters: |
|
---|---|
Returns: | The instance of GPS.Menu that was created |
General interface to version control activities systems
Creates a new activity and returns its instance
Parameters: | name – Activity name to be given to this instance |

Dummy function, whose goal is to prevent user-creation of a :class:GPS.AreaContext instance. Such instances can only be created internally by GPS.
Return the last selected line in the context.
Returns: | An integer |
---|
Return the first selected line in the context.
Returns: | An integer |
---|
This class provides access to GPS’s bookmarks. These are special types of markers that are saved across sessions, and can be used to save a context within GPS. They are generally associated with a specific location in an editor, but can also be used to locate special boxes in a graphical browser, for example.
This function prevents the creation of a bookmark instance directly. You must use GPS.Bookmark.get() instead, which always returns the same instance for a given bookmark, thus allowing you to save your own custom data with the bookmark
See also
This function creates a new bookmark at the current location in GPS. If the current window is an editor, it creates a bookmark that will save the exact line and column, so the user can go back to them easily. Name is the string that appears in the bookmarks window, and that can be used later to query the same instance using GPS.Bookmark.get(). This function emits the hook bookmark_added.
Parameters: | name – A string |
---|---|
Returns: | An instance of GPS.Bookmark |
See also
GPS.MDI.get("file.adb").raise_window()
bm = GPS.Bookmark.create("name")
Delete an existing bookmark. This emits the hook bookmark_removed.
Retrieves a bookmark by its name. If no such bookmark exists, an exception is raised. The same instance of :class:GPS.Bookmark is always returned for a given bookmark, so you can store your own user data within the instance. Note however that this custom data will not be automatically preserved across GPS sessions, so you may want to save all your data when GPS exits
Parameters: | name – A string |
---|---|
Returns: | An instance of GPS.Bookmark |
See also
GPS.Bookmark.get("name").my_own_field = "GPS"
print GPS.Bookmark.get("name").my_own_field # prints "GPS"
Changes the current context in GPS so it matches the one saved in the bookmark. In particular, if the bookmark is inside an editor, this editor is raised, and the cursor moved to the correct line and column. You cannot query directly the line and column from the bookmark, since these might not exist, for instance when the editor points inside a browser.
Return the list of all existing bookmarks.
Returns: | A list of :class`GPS.Bookmark` instances |
---|
# The following command returns a list with the name of all
# existing purposes
names = [bm.name() for bm in GPS.Bookmark.list()]
Return the current name of the bookmark. It might not be the same one that was used to create or get the bookmark, since the user might have used the bookmarks view to rename it.
Returns: | A string |
---|
Rename an existing bookmark. This updates the bookmarks view automatically, and emits the hooks bookmark_removed and bookmark_added.
Parameters: | name – A string |
---|
This class provides an interface to the GPS build targets. Build targets can be configured through XML or through the Target Configuration dialog.
Initializes a new instance of the class BuildTarget. name must correspond to an existing target.
Parameters: | name – Name of the target associated with this instance |
---|
compile_file_target=GPS.BuildTarget("Compile File")
compile_file_target.execute()
Clone the target to a new target. All the properties of the new target are copied from the target. Any graphical element corresponding to this new target is created.
Parameters: |
|
---|
Launch the build target.
Parameters: |
|
---|
Hide target from menus and toolbar.
Remove target from the list of known targets. Any graphical element corresponding to this target is also removed.
Show target in menus and toolbar where it was before hiding.
This class represents a button that can be pressed to trigger various actions.

Initializes a new button. When the button is pressed by the user, on_click() is called with the a single parameter, self.
Parameters: |
|
---|
def on_click (button):
print "Button pressed"
button = GPS.Button ("my_id", label="Press me", on_click=on_click)
GPS.Toolbar().append (button)
Changes the text that appears on the button.
Parameters: | label – A string |
---|
This class provides an interface to the GPS clipboard. This clipboard contains the previous selections that were copied or cut from a text editor. Several older selections are also saved so that they can be pasted later on.
This function returns the contents of the clipboard. Each item in the list corresponds to a past selection, the one at position 0 being the most recent. If you want to paste text in a buffer, you should paste the text at position GPS.Clipboard.current() rather than the first in the list.
Returns: | A list of strings |
---|
Copies a given static text into the clipboard. It is better in general to use GPS.EditorBuffer.copy(), but it might happen that you need to append text that do not exist in the buffer.
Parameters: |
|
---|
See also
This function returns the index, in GPS.Clipboard.contents(), of the text that was last pasted by the user. If you were to select the menu /Edit/Paste, that would be the text pasted by GPS. If you select /Edit/Paste Previous, current will be incremented by 1, and the next selection in the clipboard is pasted.
Returns: | An integer |
---|
This function merges two levels of the clipboard, so that the one at index index1 now contains the concatenation of both. The one at index2 is removed.
Parameters: |
|
---|
This class is a toolset that allows handling CodeAnalysis instances.
Raises an exception to prevent users from creating new instances.

Parses the output of a tool and suggests auto-fix possibilities whenever possible. This adds small icons in the location window, so that the user can click on it to fix compilation errors. You should call Locations.parse() with the same output prior to calling this command.
The regular expression specifies how locations are recognized. By default, it matches file:line:column. The various indexes indicate the index of the opening parenthesis that contains the relevant information in the regular expression. Set it to 0 if that information is not available.
Access the various suggested fixes through the methods of the Codefix class.
Parameters: |

This class gives access to a command-line window that pops up on the screen. This window is short-lived (in fact there can be only one such window at any given time) and any key press is redirected to that window. It can be used to interactively query a parameter for an action, for example.
Among other things, it is used in the implementation of the interactive search facility, where each key pressed should be added to the search pattern instead of to the editor.
class Isearch(CommandWindow):
def __init__(self):
CommandWindow.__init__(
self, prompt="Pattern",
on_key=self.on_key,
on_changed=self.on_changed)
def on_key(self, input, key, cursor_pos):
if key == "control-w":
.... # Copy current word from editor into the window
self.write(input[:cursor_pos + 1] +
"FOO" + input[cursor_pos + 1:])
return True ## No further processing needed
return False
def on_changed(self, input, cursor_pos):
## Search for next occurrence of input in buffer

Initializes an instance of a command window. An exception is raised if such a window is already active in GPS. Otherwise, the new window is popped up on the screen. Its location depends on the global_window parameter: if true, the command window is displayed at the bottom of the GPS window and occupies its whole width. If false, it is displayed at the bottom of the currently selected window.
The prompt is the short string displayed just before the command line itself. Its goal is to indicate to the user what he is entering.
The last four parameters are callbacks:
Parameters: |
|
---|
Returns the current contents of the command window.
Returns: | A string |
---|
Changes the background color of the command window. This can be used to make the command window more obvious or to highlight errors by changing the color. If the color parameter is not specified, the color reverts to its default.
Parameters: | color – A string |
---|
Changes the prompt displayed before the text field.
Parameters: | prompt – A string |
---|
This function replaces the current content of the command line. As a result, you should make sure to preserve the character you want, as in the on_key() callback in the example above. Calling this function also results in several calls to the on_changed() callback, one of them with an empty string (since gtk first deletes the contents and then writes the new contents).
The cursor parameter can be used to specify where the cursor should be left after the insertion. -1 indicates the end of the string.
Parameters: |

This class is used to create and interact with the interactive consoles in GPS. It can be used to redirect the output of scripts to various consoles in GPS, or to get input from the user has needed.
# The following example shows how to redirect the output of a script to
# a new console in GPS:
console = GPS.Console("My_Script")
console.write("Hello world") # Explicit redirection
# The usual Python's standard output can also be redirected to this
# console:
sys.stdout = GPS.Console("My_Script")
print "Hello world, too" # Implicit redirection
sys.stdout = GPS.Console("Python") # Back to python's console
sys.stdout = GPS.Console() # Or back to GPS's console
# The following example shows an integration between the GPS.Console
# and GPS.Process classes, so that a window containing a shell can be
# added to GPS.
# Note that this class is in fact available directly through "from
# gps_utils.console_process import Console_Process" if you need it in
# your own scripts.
import GPS
class Console_Process(GPS.Console, GPS.Process):
def on_output(self, matched, unmatched):

Creates a new instance of GPS.Console. GPS tries to reuse any existing console with the same name. If none exists yet, or the parameter force is set to True, GPS creates a new console.
You cannot create the Python and Shell consoles through this call. If you tryu, an exception is raised. Instead, use GPS.execute_action() (“/Tools/Consoles/Python”), and then get a handle on the console through GPS.Console. This is because these two consoles are tightly associated with each of the scripting languages.
If GPS reuses an existing console, on_input() overrides the callback that was already set on the console, while on_destroy() is called in addition to the one that was already set on the console.
If this is not the desired behavior, you can also call destroy() on the console and call the constructor again.
The function on_input() is called whenever the user has entered a new command in the console and pressed <enter> to execute it. It is called with the following parameters:
See the function GPS.Console.set_prompt_regexp() for proper handling of input in the console.
The subprogram on_destroy() is called whenever the user closes the console. It is called with a single parameter:
The subprogram on_completion() is called whenever the user presses Tab in the console. It is called with a single parameter:
The default implementation inserts a tab character, but you can to add additional user input through GPS.Console.add_input() for example.
The subprogram on_resize() is called whenever the console is resized by the user. It is passed three parameters:
This is mostly useful when a process is running in the console, in which case you can use GPS.Process.set_size() to let the process know the size. Note that the size passed to this callback is conservative: since all characters might not have the same size, GPS tries to compute the maximal number of visible characters and pass this to the callback, but the exact number of characters might depend on the font.
The subprogram on_interrupt() is called when the user presses Ctrl-c in the console. It receives a single parameter, the instance of GPS.Console. By default a Ctrl-c is handled by GPS itself by killing the last process that was started.
As described above, GPS provides a high-level handling of consoles, where it manages histories, completion, command line editing and execution on its own through the callbacks described above. This is usually a good thing and provides advanced functionalities to some programs that lack them. However, there are cases where this gets in the way. For example, if you want to run a Unix shell or a program that manipulates the console by moving the cursor around on its own, the high-level handling of GPS gets in the way. In such a case, the following parameters can be used: on_key, manage_prompt and ansi.
ansi should be set to true if GPS should emulate an ANSI terminal. These are terminals that understand certain escape sequences that applications sent to move the cursor to specific positions on screen or to change the color and attributes of text.
manage_prompt should be set to False to disable GPS’s handling of prompts. In general, this is incompatible with using the on_input() callback, since GPS no longer distinguishes what was typed by the user and what was written by the external application. This also means that the application is free to write anywhere on the screen. This should in general be set to True if you expect your application to send ANSI sequences.
on_key() is a function called every time the user presses a key in the console. This is much lower-level than the other callbacks above, but if you are driving external applications you might have a need to send the keys as they happen, and not wait for a newline. on_key() receives four parameters:
Parameters: |
|
---|
Returns True if the console accepts input, False otherwise.
Returns: | A boolean |
---|
Adds extra text to the console as if the user had typed it. As opposed to text inserted using GPS.Console.write(), this text remains editable by the user.
Parameters: | text – A string |
---|
Clears the current contents of the console.
Removes any user input that the user has started typing (i.e., since the last output inserted through GPS.Console.write()).
Copies the selection to the clipboard.
Registers a regular expression that should be highlighted in this console to provide hyperlinks, which are searched for when calling GPS.Console.write_with_links(). The part of the text that matches any of the link registered in the console through GPS.Console.create_link() is highlighted in blue and underlined, just like a hyperlink in a web browser. If the user clicks on that text, on_click() is called with one parameter, the text that was clicked on. This can, for example, be used to jump to an editor or open a web browser.
If the regular expression does not contain any parenthesis, the text that matches the whole regexp is highlighted as a link. Otherwise, only the part of the text that matches the first parenthesis group is highlighted (so you can test for the presence of text before or after the actual hyper link).
Parameters foreground and background specify colors to visualize matched text, while underline turns underscore on.
Parameters: |
|
---|
See also
Drops each regular expression registered with create_link().
Makes the console accept or reject input according to the value of “enable”.
Parameters: | enable – A boolean |
---|
Does nothing, needed for compatibility with Python’s file class.
Returns the content of the console.
Returns: | A string |
---|
Returns True if the console behaves like a terminal. Mostly needed for compatibility with Python’s file class.
Returns: | A boolean |
---|
Reads the available input in the console. Currently, this behaves exactly like readline().
Returns: | A String |
---|
Asks the user to enter a new line in the console, and returns that line. GPS is blocked until enter has been pressed in the console.
Returns: | A String |
---|
Selects the complete contents of the console.
Outputs some text on the console. This text is read-only. If the user started typing some text, that text is temporarily removed, the next text is inserted (read-only), and the user text is put back.
The optional parameter mode specifies the kind of the output text: “text” for ordinary messages (this is default), “log” for log messages, and “error” for error messages.
Parameters: |
|
---|

Console().write(
u"\N{LATIN CAPITAL LETTER E WITH ACUTE}".encode("utf-8")
)
Outputs some text on the console, highlighting the parts of it that match the regular expression registered by GPS.Console.create_link().
Parameters: | text – A utf8 string |
---|
import re
console = GPS.Console("myconsole")
console.create_link("(([\w-]+):(\d+))", open_editor)

This class is a general interface to the contextual menus in GPS. It gives you control over which menus should be displayed when the user right clicks in parts of GPS.
See also
Initializes a new instance of GPS.Contextual. The name is what was given to the contextual menu when it was created and is a static string independent of the actual label used when the menu is displayed (and which is dynamic, depending on the context). You can get the list of valid names by checking the list of names returned by GPS.Contextual.list().
Parameters: | name – A string |
---|

# You could for example decide to always hide the "Goto
# declaration" contextual menu with the following call:
GPS.Contextual ('Goto declaration of entity').hide()
# After this, the menu will never be displayed again.
Creates a new contextual menu entry. Whenever this menu entry is selected by the user, GPS executes on_activate(), passing one parameter which is the context for which the menu is displayed (this is usually the same as GPS.current_contextual()).
If on_activate is None, a separator is created.
The filter parameter can be used to filter when the entry should be displayed in the menu. It is a function that receives one parameter, an instance of GPS.Context, and returns a boolean. If it returns True, the entry is displayed, otherwise it is hidden.
The label parameter can be used to control the text displayed in the contextual menu. By default, it is the same as the contextual name (used in the constructor to GPS.Contextual.__init__()). If specified, it must be a subprogram that takes an instance of GPS.Context in a parameter and returns a string, which is displayed in the menu.
The parameters group, ref and add_before can be used to control the location of the entry within the contextual menu. group allows you to create groups of contextual menus that will be put together. Items of the same group appear before all items with a greater group number. ref is the name of another contextual menu entry, and add_before indicates whether the new entry is put before or after that second entry.

self.data = "Menu Name"
self.create(on_activate=self.on_contextual,
filter=self.on_filter,
label=self.label)
Creates a new dynamic contextual menu.
This is a submenu of a contextual menu, where the entries are generated by the factory parameter. This parameter should return a list of strings, which will be converted to menus by GPS. These strings can contain ‘/’ characters to indicate submenus.
filter is a subprogram that takes the GPS.Context as a parameter and returns a boolean indicating whether the submenu should be displayed.
label can be used to specify the label to use for the menu entry. It can include directory-like syntax to indicate submenus. This label can include standard macro substitution (see the GPS documentation), for instance %e for the current entity name.
on_activate is called whenever any of the entry of the menu is selected, and is passed three parameters, the context in which the contextual menu was displayed, the string representing the selected entry and the index of the selected entry within the array returned by factory (index starts at 0).
The parameters ref and add_before can be used to control the location of the entry within the contextual menu. ref is the name of another contextual menu entry, and add_before indicates whether the new entry is put before or after that second entry.

Controls whether the contextual menu is grayed-out: False if it should be grayed-out, True otherwise.
Parameters: | Sensitivity – Boolean value |
---|
Makes sure the contextual menu is shown when appropriate. The entry might still be invisible if you right clicked on a context where it does not apply, but it will be checked.

Interface to a cursor in GPS.EditorBuffer. Only gives access to the insertion mark and to the selection mark of the cursor.
x.__init__(...) initializes x; see help(type(x)) for signature
Returns the cursor’s main mark.
NOTE: If you can interact with your cursor via Cursor.move() rather than via manually moving marks, you should prefer that method.
Returns: | The GPS.EditorMark instance corresponding to the cursor’s insert mark |
---|
Moves the cursor to the given location.
Parameters: |
|
---|
Returns the cursor’s selection mark.
NOTE: If you can interact with your cursor via Cursor.move() rather than via manually moving marks, you should prefer that method.
Returns: | The GPS.EditorMark instance corresponding to the cursor’s selection mark |
---|
Sets the buffer in manual sync mode regarding this cursor. This set sync to be manual and all insertions/deletions are considered as originating from this cursor instance. If you do not do this, an action on the buffer (like an insertion) is repercuted on every alive cursor instance.
NOTE: Do not call this manually. Instead, iterate on the results of EditorBuffer.cursors() so this method is called for you automatically.
Interface to debugger related commands. This class allows you to start a debugger and send commands to it. By connection to the various debugger_* hooks, you can also monitor the state of the debugger.
By connecting to the “debugger_command_action_hook”, you can also create your own debugger commands, that the user can then type in the debugger console. This is a nice way to implement debugger macros.
While developping such debugger interfaces, it might be useful to modify the file $HOME/.gps/traces.cfg, and add a line “GVD.Out=yes” in it. This copies all input/output with the debuggers into the GPS log file.

d.send("begin")
d.send("next")
d.send("next")
d.send("graph display A")
GPS.Hook("debugger_process_stopped").add(debugger_stopped)
It is an error to create a Debugger instance directly. Instead, use GPS.Debugger.get() or GPS.Debugger.spawn().
Closes the given debugger. This also closes all associated windows (such as the call stack and console).
Returns the command being executed in the debugger. This is often only available when called from the “debugger_state_changed” hook, where it might also indicate the command that just finished.
Returns: | A string |
---|
Gives access to an already running debugger, and returns an instance of GPS.Debugger attached to it. The parameter can be null, in which case the current debugger is returned, it can be an integer, in which case the corresponding debugger is returned (starting at 1), or it can be a file, in which case this function returns the debugger currently debugging that file.
Parameters: | id – Either an integer or an instance of GPS.File |
---|---|
Returns: | An instance of GPS.Debugger |
Returns the name of the executable currently debugged in the debugger.
Returns: | An instance of GPS.File |
---|

Interface for handling customized documentation generation. This class is used in conjunction with GPS.DocgenTagHandler. You cannot directly create this class. Instead, use the ones furnished by GPS.DocgenTagHandler() callbacks.
See also
Creates a new Index file. The file filename will be titled name and will contain the general decoration along with content`. All other generated documentation files will have a link to it, for convenience.
Parameters: |
|
---|
Retrieves the current analysed source file. You should call this method only from a GPS.DocgenTagHandler.on_match() callback.
Returns: | A GPS.File instance |
---|
Retrieves the directory that will contain the documentation. You should call this method only from a GPS.DocgenTagHandler.on_match() callback.
Returns: | A GPS.File instance |
---|
Registers a new CSS file to use when generating the documentation. This allows to overriding a default style or adding new ones for custom tag handling.
Parameters: | filename – A file name |
---|
Registers the file to be used as main page (e.g. index.html). By default, the first page generated in the Table of Contents is used.
Parameters: | filename – A file name |
---|
Registers a new tag handler. This handler will be used each time a new documentation is generated and the corresponding tag is found.
Parameters: | handler – The handler to register |
---|
# register a default handler for tag <description>
# that is, -- <description>sth</description>
# will be translated as <div class="description">sth</div>

on_match is a callback that is called each time a tag corresponding to the GPS.DocgenTagHandler is analysed. It takes the following parameters:
on_start is a callback that is called each time a documentation generation starts. It takes the following parameters:
on_exit is a callback that is called each time a documentation generation finishes. It takes the following parameters:
Using the default values of the callbacks (e.g. None), the GPS.DocgenTagHandler() handler will translate comments of the form “– <tag>value</tag>” by “<div class=”tag”>value</div>”.

OBSOLESCENT.
Removes highlights for a portion of a line in a file.
Parameters: |
|
---|
This class represents the physical contents of a file. It is always associated with at least one view (a GPS.EditorView instance), which makes it visible to the user. The contents of the file can be manipulated through this class.
Prevents the direct creation of instances of EditorBuffer. Use GPS.EditorBuffer.get() instead
Adds a new slave cursor at the given location.
Returns: | The resulting Cursor instance |
---|
Adds one non-editable line to the buffer, starting at line start_line and containing the string text. If category is specified, use it for highlighting. Creates a mark at beginning of block and return it. If name is specified, the returned mark has this name.
Parameters: |
|
---|---|
Returns: | An instance of GPS.EditorMark |
See also
Applies the overlay to the given range of text. This immediately changes the rendering of the text based on the properties of the overlay.
Parameters: |
|
---|
See also
Returns a new location at the given line and column in the buffer.
Returns: | A new instance of GPS.EditorLocation |
---|
Returns a location pointing to the first character in the buffer.
Returns: | An instance of GPS.EditorLocation |
---|
Folds all the blocks in all the views of the buffer. Block folding is a language-dependent feature, where one can hide part of the source code temporarily by keeping only the first line of the block (for instance the first line of a subprogram body, the rest is hidden). A small icon is displayed to the left of the first line so it can be unfolded later.
Unfolds all the blocks that were previously folded in the buffer, ie make the whole source code visible. This is a language dependent feature.
Returns the total number of characters in the buffer.
Returns: | An integer |
---|
Closes the editor and all its views. If the buffer has been modified and not saved, a dialog is open asking the user whether to save. If force is True, do not save and do not ask the user. All changes are lost.
Parameters: | force – A boolean |
---|
Copies the given range of text into the clipboard, so that it can be further pasted into other applications or other parts of GPS. If append is True, the text is appended to the last clipboard entry instead of generating a new one.
Parameters: |
|
---|
See also
Creates a new overlay. Properties can be set on this overlay, which can then be applied to one or more ranges of text to changes its visual rqendering or to associate user data with it. If name is specified, this function will return an existing overlay with the same name in this buffer if any can be found. If the name is not specified, a new overlay is created. Changing the properties of an existing overlay results in an immediate graphical update of the views associated with the buffer.
A number of predefined overlays exit. Among these are the ones used for syntax highlighting by GPS itself, which are “keyword”, “comment”, “string”, “character”. You can use these to navigate from one comment section to the next for example.
Parameters: | name – A string |
---|---|
Returns: | An instance of GPS.EditorOverlay |
Returns the last view used for this buffer, ie the last view that had the focus and through which the user might have edited the buffer’s contents.
Returns: | An instance of GPS.EditorView |
---|
Returns a list of Cursor instances. This method returns a generator that automatically handles the calls to set_manual_sync() for each cursor and the call to update_cursors_selection() at the end.
Returns: | A list of Cursor instances |
---|
# To perform action on every cursors of the current editor
# This will move every cursor forward 1 char
ed = GPS.EditorBuffer.get()
for cursor in ed.cursors():
cursor.move(c.mark().location().forward_char())
Copies the given range of text into the clipboard so that it can be further pasted into other applications or other parts of GPS. The text is removed from the edited buffer. If append is True, the text is appended to the last clipboard entry instead of generating a new one.
Parameters: |
|
---|
Deletes the given range of text from the buffer.
Parameters: |
|
---|
Returns a location pointing to the last character in the buffer.
Returns: | An instance of GPS.EditorLocation |
---|
Expands given alias in the editor buffer at the point where the cursor is.
Cancels the grouping of commands on the editor. See GPS.EditorBuffer.start_undo_group().
If file is already opened in an editor, get a handle on its buffer. This instance is then shared with all other buffers referencing the same file. As a result, you can, for example, associate your own data with the buffer, and retrieve it at any time until the buffer is closed. If the file is not opened yet, it is loaded in a new editor, and a new view is opened at the same time (and thus the editor becomes visible to the user). If the file is not specified, the current editor is returned, which is the last one that had the keyboard focus.
If the file is not currently open, the behavior depends on open:; if true, a new editor is created for that file, otherwise None is returned.
When a new file is open, it has received the focus. But if the editor already existed, it is not raised explicitly, and you need to do it yourself through a call to GPS.MDIWindow.raise_window() (see the example below).
If force is true, a reload is forced in case the file is already open.
Parameters: |
|
---|---|
Returns: | An instance of GPS.EditorBuffer |
ed = GPS.EditorBuffer.get(GPS.File ("a.adb"))
GPS.MDI.get_by_child(ed.current_view()).raise_window()
ed.data = "whatever"
# ... Whatever, including modifying ed
ed = GPS.EditorBuffer.get(GPS.File("a.adb"))
ed.data # => "whatever"
Returns the contents of the buffer between the two locations given in parameter. Modifying the returned value has no effect on the buffer.
Parameters: |
|
---|---|
Returns: | A string |
Returns a list of Cursor instances. Note that if you intend to perform actions with them (in particular deletions/insertions), you should call set_manual_sync, on the cursor’s instance. Also, if you move any selection mark, you should call update_cursors_selection afterwards.
There is a higher level method, EditorBuffer.cursors() that returns a generator that will handle this manual work for you.
Returns: | A list of Cursor instances |
---|
Checks whether there is a mark with that name in the buffer, and return it. An exception is raised if there is no such mark.
Parameters: | name – A string |
---|---|
Returns: | An instance of GPS.EditorMark |

Parameters: |
|
---|
Removes all active slave cursors from the buffer.

Parameters: |
|
---|
See also
Removes specified number of special lines at the specified mark. It does not delete the mark.
Parameters: |
|
---|
Saves the buffer to the given file. If interactive is true, a dialog is open to ask for confirmation from the user first, which gives him a chance to cancel the saving. interactive is ignored if file is specified.
Parameters: |
|
---|
Selects an area in the buffer. The boundaries are included in the selection. The order of the boundaries is irrelevant, but the cursor is be left on to.
Parameters: |
|
---|
Returns the character after the end of the selection. This is always located after the start of the selection, no matter what the order of parameters given to GPS.EditorBuffer.select() is. If the selection is empty, EditorBuffer.selection_start() and EditorBuffer.selection_end() will be equal.
Returns: | An instance of GPS.EditorLocation |
---|
# To get the contents of the current selection, one would use:
buffer = GPS.EditorBuffer.get()
selection = buffer.get_chars(
buffer.selection_start(), buffer.selection_end() - 1)
Returns the start of the selection. This is always located before the end of the selection, no matter what the order of parameters passed to GPS.EditorBuffer.select() is.
Returns: | An instance of GPS.EditorLocation |
---|
Sets the buffer in auto sync mode regarding multi cursors. This means that any insertion/deletion will be propagated in a ‘naive’ way on all multi cursors. Cursor movements will not be propagated.
Indicates whether the user should be able to edit the buffer interactively (through any view).
Parameters: | read_only – A boolean |
---|
See also
Starts grouping commands on the editor. All future editions are considered as belonging to the same group. finish_undo_group() should be called once for every call to start_undo_group().
Undoes the last command in the editor.
Cancels the current selection in the buffer.
Updates the overlay used to show the multi cursor’s current selection. This must be called after any operation on multi cursor selection marks
Returns the list of all views currently editing the buffer. There is always at least one such view. When the last view is destroyed, the buffer itself is destroyed.
Returns: | A list of GPS.EditorView instances |
---|
This class can be used to transform source editor text into hyperlinks when the Control key is pressed. Two actions can then be associated with this hyperlink: clicking with the left mouse button on the hyperlink triggers the primary action, and clicking with the middle mouse button on the hyperlink triggers the alternate action.
Register a highlighter. The action is a Python function that takes a string as a parameter: the string being passed is the section of text which is highlighted.
Parameters: |
|
---|
# Define an action
def view_html(url):
GPS.HTML.browse (url)
def wget_url(url):
def on_exit_cb(self, code, output):
GPS.Editor.edit (GPS.dump (output))
p=GPS.Process("wget %s -O -" % url, on_exit=on_exit_cb)
# Register a highlighter to launch a browser on any URL
# left-clicking on an URL will open the default browser to
# this URL middle-clicking will call "wget" to get the
# source of this URL and open the output in a new editor
h=GPS.EditorHighlighter ("http(s)?://[^\s:,]*", view_html,
0, wget_url)
# Remove the highlighter
h.remove()
Unregister the highlighter. This cannot be called while the hyper-mode is active.
This class represents a location in a specific editor buffer. This location is not updated when the buffer changes, but will keep pointing to the same line/column even if new lines are added in the buffer. This location is no longer valid when the buffer itself is destroyed, and the use of any of these subprograms will raise an exception.
See also
Initializes a new instance. Creating two instances at the same location will not return the same instance of GPS.EditorLocation, and therefore any user data you have stored in the location will not be available in the second instance.
Parameters: |
|
---|
ed = GPS.EditorBuffer.get(GPS.File("a.adb"))
loc = ed.at(line=4, column=5)
loc.data = "MY OWN DATA"
loc2 = ed.at(line=4, column=5)
# loc2.data is not defined at this point

This class represents a specific location in an open editor. As opposed to the GPS.EditorLocation class, the exact location is updated whenever the buffer is modified. For example, if you add a line before the mark, then the mark is moved one line forward as well, so that it still points to the same character in the buffer.
The mark remains valid even if you close the buffer; or if you reopen it and modify it. It will always point to the same location in the file, while you have kept the Python object.
GPS.EditorLocation.create_mark() allows you to create named marks which you can then retrieve through GPS.EditorBuffer.get_mark(). Such named marks are only valid while the editor exists. As soon as you close the editor, you can no longer use get_mark to retrieve it (but the mark is still valid if you have kept a python object referencing it).
See also
Always raises an exception, thus preventing the direct creation of a mark. Instead, you should use GPS.EditorLocation.create_mark() to create such a mark.
Deletes the physical mark from the buffer. All instances referencing the same mark will no longer be valid. If you have not given a name to the mark in the call to GPS.EditorLocation.create_mark(), it will automatically be destroyed when the last instance referencing it goes out of scope. Therefore, calling delete() is not mandatory in the case of unnamed marks, although it is still recommended.
Returns True if mark’s location is still present in the buffer.
Returns the current location of the mark. This location will vary depending on the changes that take place in the buffer.
Returns: | An instance of GPS.EditorLocation |
---|
ed = GPS.EditorBuffer.get(GPS.File("a.adb"))
loc = ed.at(3, 5)
mark = loc.create_mark()
# ...
loc = mark.location()
Moves the mark to a new location in the buffer. This is slightly less expensive than destroying the mark and creating a new one through GPS.EditorLocation.create_mark(), although the result is the same.
Parameters: | location – An instance of GPS.EditorLocation |
---|
This class represents properties that can be applied to one or more ranges of text. This can be used to change the display properties of the text (colors, fonts,...) or store any user-specific attributes that can be retrieved later. GPS itself uses overlays to do syntax highlighting. If two or more overlays are applied to the same range of text, the final colors and fonts of the text depends on the priorities of these overlays and the order in which they were applied to the buffer.
This class is fairly low-level; we recommend using the class gps_utils.highlighter.OverlayStyle instead. That class provides similar support for specifying attributes, but makes it easier to highlight sections of an editor with that style, or to remove the highlighting.
In fact, if your goal is to highlight parts of editors, it might be simpler to use gps_utils.highilghter.Background_Highlighter or one of the classes derived from it. These classes provide convenient support for highlighting editors in the background, i.e. without interfering with the user or slowing things down.
This subprogram is used to prevent the direct creation of overlays. Overlays need to be created through GPS.EditorBuffer.create_overlay().
See also
Retrieves one of the predefined properties of the overlay. This list of these properties is described for GPS.EditorOverlay.set_property().
Parameters: | name – A string |
---|---|

The set of predefined attributes is fixed. However, overlays are especially useful to store your own user data in the usual Python manner, which you can retrieve later. This can be used to mark specially specific ranges of text which you want to be able to find easily later on, even if the buffer has been modified since then (see GPS.EditorLocation.forward_overlay()).
Parameters: |
|
---|
One view of an editor, i.e., the visible part through which users can modify text files. A given GPS.EditorBuffer can be associated with multiple views. Closing the last view associated with a buffer will also close the buffer.
# To get a handle on the current editor, use the following code:
view = GPS.EditorBuffer.get().current_view()
digraph inheritanceaf5dc14539 { rankdir=LR; size="8.0, 12.0"; "GPS.EditorView" [style="setlinewidth(0.5)",URL="#GPS.EditorView",fontname="Vera Sans, DejaVu Sans, Liberation Sans, Arial, Helvetica, sans",tooltip="One view of an editor, i.e., the visible part through which users can",height=0.25,shape=box,fontsize=10]; "GPS.GUI" -> "GPS.EditorView" [arrowsize=0.5,style="setlinewidth(0.5)"]; "GPS.GUI" [style="setlinewidth(0.5)",URL="#GPS.GUI",fontname="Vera Sans, DejaVu Sans, Liberation Sans, Arial, Helvetica, sans",tooltip="This is an abstract class (ie no instances of it can be created from your",height=0.25,shape=box,fontsize=10]; }
Called implicitly whenever you create a new view. It creates a new view for the given buffer, and is automatically inserted into the GPS MDI.
Parameters: | buffer – An instance of GPS.EditorBuffer |
---|
Returns the buffer to which the view is attached. Editing the text of the file should be done through this instance.
Returns: | An instance of GPS.EditorBuffer |
---|
Scrolls the view so that the location is centered.
Parameters: | location – An instance of GPS.EditorLocation |
---|
Returns the current location of the cursor in this view.
Returns: | An instance of GPS.EditorLocation |
---|
Returns: | A boolean, whether the user is currently performing a selection. This should impact cursor movements (since moving the cursor should extend the selection). |
---|
Moves the cursor to the given location. Each view of a particular buffer has its own cursor position, which is where characters typed by the user will be inserted. If extend_selection is True, extend the selection from the current bound to the new location.
Parameters: |
|
---|
Whether the view is editable or not. This property is shared by all views of the same buffer.
Returns: | A boolean |
---|
See also
Sets the mode for cursor movement. When the parameter is true, moving the cursor extends the selection (for instance shift+cursor keys, or the Emacs mode of setting the mark with ctrl-space and then moving the cursor). When the parameter is false, cursor movement cancels the selection.
Parameters: | extend – A boolean |
---|
Indicates whether the user should be able to edit interactively through this view. Setting a view Writable/Read Only will also modify the status of the other views of the same buffer.
Parameters: | read_only – A boolean |
---|
See also
GPS.EditorBuffer.get_read_only()
Returns the view’s title; the short title is returned if short is set to True.
Parameters: | short – A boolean |
---|
Represents an entity from the source, based on the location of its declaration.
See also
Initializes a new instance of the Entity class from any reference to the entity. The file parameter should only be omitted for a predefined entity of the language. This will only work for languages for which a cross-reference engine has been defined
Parameters: |
|
---|
>>> GPS.Entity("foo", GPS.File("a.adb"),
10, 23).declaration().file().name()
=> will return the full path name of the file in which the entity
"foo", referenced in a.adb at line 10, column 23, is defined.
Returns various boolean attributes of the entity: is the entity global, static, etc.
Returns: | A htable with the following keys: - ‘global’: whether the entity is a global entity - ‘static’: whether the entity is a local static variable (C/C++) - ‘in’: for an in parameter for an Ada subprogram - ‘out’: for an out parameter for an Ada subprogram - ‘inout’: for an in-out parameter for an Ada subprogram - ‘access’: for an access parameter for an Ada subprogram |
---|
Returns the location at which the implementation of the entity is found. For Ada subprograms and packages, this corresponds to the body of the entity. For Ada private types, this is the location of the full declaration for the type. For entities which do not have a notion of body, this returns the location of the declaration for the entity. Some entities have several bodies. This is for instance the case of a separate subprogram in Ada, where the first body just indicates the subprogram is separate, and the second body provides the actual implementation. The nth parameter gives access to the other bodies. An exception is raised when there are not at least nth bodies.
Parameters: | nth – An integer |
---|---|
Returns: | An instance of GPS.FileLocation |
entity = GPS.Entity("bar", GPS.File("a.adb"), 10, 23)
body = entity.body()
print "The subprogram bar's implementation is found at " + body.file.name() + ':' + body.line() + ':' + body.column()
Displays the list of entities that call the entity. The returned value is a dictionary whose keys are instances of Entity calling this entity, and whose value is a list of FileLocation instances where the entity is referenced. This command might take a while to execute, since GPS needs to get the cross-reference information for lots of source files. If dispatching_calls is true, then calls to self that might occur through dispatching are also listed.
Parameters: | dispatching_calls – A boolean |
---|---|
Returns: | A dictionary, see below |
Opens the call graph browser to show what entities call self.
Displays the list of entities called by the entity. The returned value is a dictionary whose keys are instances of Entity called by this entity, and whose value is a list of FileLocation instances where the entity is referenced. If dispatching_calls is true, calls done through dispatching will result in multiple entities being listed (i.e., all the possible subprograms that are called at that location).
Parameters: | dispatching_calls – A boolean |
---|---|
Returns: | A dictionary, see below |
See also
GPS.Entity.is_called_by()
Returns the category of a given entity. Possible values include: label, literal, object, subprogram, package, namespace, type, and unknown. The exact list of strings is not hard-coded in GPS and depends on the programming language of the corresponding source.
See instead is_access(), is_array(), is_subprogram(), etc.
Returns: | A string |
---|
Returns the location of the declaration for the entity. The file’s name is is “<predefined>” for predefined entities.
Returns: | An instance of GPS.FileLocation where the entity is declared |
---|
entity=GPS.Entity("integer")
if entity.declaration().file().name() == "<predefined>":
print "This is a predefined entity"
Returns a list of all the entities that are derived from self. For object-oriented languages, this includes types that extend self. In Ada, this also includes subtypes of self.
Returns: | A list of GPS.Entity |
---|
Returns the list of discriminants for entity. This is a list of entities, empty if the type has no discriminant or if this notion does not apply to the language.
Returns: | A list of instances of GPS.Entity |
---|
Returns the documentation for the entity. This is the comment block found just before or just after the declaration of the entity (if any such block exists). This is also the documentation string displayed in the tooltips when you leave the mouse cursor over an entity for a while. If extended is true, the returned documentation includes formatting and the full entity description.
Parameters: | extended – A boolean |
---|---|
Returns: | A string |
Returns the location at which the end of the entity is found.
Returns: | An instance of GPS.FileLocation |
---|
Returns the list of fields for the entity. This is a list of entities. This applies to Ada record and tagged types, or C structs for instance.
In older versions of GPS, this used to return the literals for enumeration types, but these should now be queried through self.literals() instead.
Returns: | A list of instances of GPS.Entity |
---|
Displays in the Locations view all the references to the entity. If include_implicit is true, implicit uses of the entity are also referenced, for example when the entity appears as an implicit parameter to a generic instantiation in Ada.
Parameters: | include_implicit – A boolean |
---|
See also
Returns the full name of the entity that it to say the name of the entity prefixed with its callers and parent packages names. The casing of the name has been normalized to lower-cases for case-insensitive languages.
Returns: | A string, the full name of the entity |
---|
Whether self is a pointer or access (variable or type)
Returns: | A boolean |
---|

Returns: | A boolean |
---|
Whether the entity is a subprogram, procedure or function.
Returns: | A boolean |
---|
Whether self is a type declaration (as opposed to a variable).
Returns: | A boolean |
---|
Returns the list of literals for an enumeration type.
Returns: | A list of instances of GPS.Entity |
---|
Returns the list of primitive operations (aka methods) for self. This list is not sorted.
Parameters: | include_inherited – A boolean |
---|---|
Returns: | A list of instances of GPS.Entity |
Returns the name of the entity. The casing of the name has been normalized to lower-cases for case-insensitive languages.
Returns: | A string, the name of the entity |
---|
Refactors the code at the location, to add named parameters. This only work if the language has support for such parameters, namely Ada for now.
Parameters: | location – An instance of GPS.FileLocation |
---|
GPS.Entity("foo", GPS.File("decl.ads")).rename_parameters(
GPS.FileLocation(GPS.File("file.adb"), 23, 34))
Returns the list of parameters for entity. This is a list of entities. This applies to subprograms.
Returns: | A list of instances of GPS.Entity |
---|
Returns the list of parent types when self is a type. For example, if we have the following Ada code:
type T is new Integer;
type T1 is new T;
then the list of parent types for T1 is [T].
Returns: | A list of GPS.Entity |
---|
Returns the type pointed to by entity. If self is not a pointer (or an Ada access type), None is returned. This function also applies to variables, and returns the same information as their type would
Returns: | An instance of GPS.Entity |
---|
## Given the following Ada code:
## type Int is new Integer;
## type Ptr is access Int;
## P : Ptr;
## the following requests would apply:
f = GPS.File("file.adb")
GPS.Entity("P", f).type() # Ptr
GPS.Entity("P", f).pointed_type() # Int
GPS.Entity("Ptr", f).pointed_type() # Int
Returns the list of type for which self is a primitive operation (or a method, in other languages than Ada).
Returns: | A list of instances of GPS.Entity or [] |
---|
Lists all references to the entity in the project sources. If include_implicit is true, implicit uses of the entity are also referenced, for example when the entity appears as an implicit parameter to a generic instantiation in Ada.
If synchronous is True, the result is returned directly, otherwise a command is returned and its result is accessible with get_result(). The result, in that case, is either a list of locations (if show_kind is False) or a htable indexed by location, and whose value is a string indicating the kind of the reference (such as declaration, body, label, or end-of-spec). in_file can be used to limit the search to references in a particular file, which is. kind_in is a list of comma-separated list of reference kinds (as would be returned when show_kind is True). Only such references are returned, as opposed to all references.
Parameters: |
|
---|---|
Returns: | A list of GPS.FileLocation, htable, or GPS.Command |
See also
for r in GPS.Entity("GPS", GPS.File("gps.adb")).references():
print "One reference in " + r.file().name()
Renames the entity everywhere in the application. The source files should have been compiled first, since this operation relies on the cross-reference information which have been generated by the compiler. If include_overriding is true, subprograms that override or are overridden by self are also renamed. Likewise, if self is a parameter to a subprogram then parameters with the same name in overriding or overridden subprograms are also renamed.
If some renaming should be performed in a read-only file, the behavior depends on make_writable: if true, the file is made writable and the renaming is performed; if false, no renaming is performed in that file, and a dialog is displayed asking whether you want to do the other renamings.
The files will be saved automatically if auto_``save is true``, otherwise they are left edited but unsaved.
Parameters: |
|
---|
Return the return type for entity. This applies to subprograms.
Returns: | An instance of GPS.Entity |
---|
Displays in the type browser the informations known about the entity, such as the list of fields for records, list of primitive subprograms or methods, and list of parameters.
Returns the type of the entity. For a variable, this its type. This function used to return the parent types when self is itself a type, but this usage is deprecated and you should be using self.parent_types() instead.
Returns: | An instance of GPS.Entity |
---|
Represents a context that contains entity information.

Dummy function, whose goal is to prevent user-creation of a GPS.EntityContext() instance. Such instances can only be created internally by GPS.
Returns the entity stored in the context.
Parameters: | approximate_search_fallback – If True, when the line and column are not exact, this parameter will trigger approximate search in the database (eg. see if there are similar entities in the surrounding lines) |
---|---|
Returns: | An instance of GPS.Entity |
One of the exceptions that can be raised by GPS. It is a general error message, and its semantic depends on what subprogram raised the exception.
digraph inheritancece9a5e228f { rankdir=LR; size="8.0, 12.0"; "GPS.Exception" [style="setlinewidth(0.5)",URL="#GPS.Exception",fontname="Vera Sans, DejaVu Sans, Liberation Sans, Arial, Helvetica, sans",tooltip="One of the exceptions that can be raised by GPS. It is a general error",height=0.25,shape=box,fontsize=10]; }
Represents a source file of your application.
See also
Initializes a new instance of the class File. This does not need to be called explicitly, since GPS calls it automatically when you create such an instance. If name is a base file name (no directory is specified), GPS attempts to search for this file in the list of source directories of the project. If a directory is specified, or the base file name was not found in the source directories, then the file name is considered as relative to the current directory. If local is “true”, the specified file name is to be considered as local to the current directory.
Parameters: |
|
---|
See also
file=GPS.File("/tmp/work")
print file.name()
Compiles the current file. This call returns only after the compilation is completed. Additional arguments can be added to the command line.
Parameters: | extra_args – A string |
---|
See also
GPS.File("a.adb").compile()
Returns the directory in which the file is found.
Returns: | A string |

## Sorting files by TN is easily done with a loop like
dirs={}
for s in GPS.Project.root().sources():
if dirs.has_key (s.directory()):
dirs[s.directory()].append (s)
else:
dirs[s.directory()] = [s]
Returns the list of entities that are either referenced (local is false) or declared (local is true) in self.
Parameters: | local – A boolean |
---|---|
Returns: | A list of GPS.Entity |
Generates the documentation of the file and displays it in the default browser.
See also
Returns the value of the property associated with the file. This property might have been set in a previous GPS session if it is persistent. An exception is raised if no such property already exists for the file.
Parameters: | name – A string |
---|---|
Returns: | A string |
See also
Returns the list of files that depends on file_name. This command might take some time to execute since GPS needs to parse the cross-reference information for multiple source files. If include_implicit is true, implicit dependencies are also returned. If include_system is true, dependent system files from the compiler runtime are also returned.
Parameters: |
|
---|---|
Returns: | A list of files |
See also
Returns the the list of files that self depends on. If include_implicit is true, implicit dependencies are also returned. If include_system is true, then system files from the compiler runtime are also considered.
Parameters: |
|
---|---|
Returns: | A list of files |
See also
Returns the name of the language this file is written in. This is based on the file extension and the naming scheme defined in the project files or the XML files. The empty string is returned when the language is unknown.
Returns: | A string |
---|
Compiles and links the file and all its dependencies. This call returns only after the compilation is completed. Additional arguments can be added to the command line.
Parameters: | extra_args – A string |
---|
See also
Returns the name of the file associated with self. This is an absolute file name, including directories from the root of the filesystem.
If remote_server is set, the function returns the equivalent path on the specified server. GPS_Server (default) is always the local machine.
Parameters: | remote_server – A string. Possible values are “GPS_Server” (or empty string), “Build_Server”, “Debug_Server”, “Execution_Server” and “Tools_Server”. |
---|---|
Returns: | A string, the name of the file |
Returns the name of the other file semantically associated with this one. In Ada this is the spec or body of the same package depending on the type of this file. In C, this will generally be the .c or .h file with the same base name.
Returns: | An instance of GPS.File |
---|
GPS.File("tokens.ads").other_file().name()
=> will print "/full/path/to/tokens.adb" in the context of the
=> project file used for the GPS tutorial.
Returns the project to which file belongs. If file is not one of the souces of the project, the returned value depends on default_to_root: if false, None is returned. Otherwise, the root project is returned.
Parameters: | default_to_root – A boolean |
---|---|
Returns: | An instance of GPS.Project |
GPS.File("tokens.ads").project().name()
=> will print "/full/path/to/sdc.gpr" in the context of the project
=> file used for the GPS tutorial
Returns all references (to any entity) within the file. The acceptable values for kind can currently be retrieved directly from the cross-references database by using a slightly convoluted approach:
sqlite3 obj/gnatinspect.db
> select display from reference_kinds;
Parameters: |
|
---|---|
Returns: | A list of tuples (GPS.Entity, GPS.FileLocation) |
Removes a property associated with a file.
Parameters: | name – A string |
---|
See also
Returns the list of matches for pattern in the file. Default values are False for case_sensitive and regexp. Scope is a string, and should be any of ‘whole’, ‘comments’, ‘strings’, ‘code’. The latter will match only for text outside of comments.
Parameters: |
|
---|---|
Returns: | A list of GPS.FileLocation instances |
Returns the next match for pattern in the file. Default values are False for case_sensitive and regexp. Scope is a string, and should be any of ‘whole’, ‘comments’, ‘strings’, ‘code’. The latter will match only for text outside of comments.
Parameters: |
|
---|---|
Returns: | An instance of GPS.FileLocation |
See also
Associates a string property with the file. This property is retrievable during the whole GPS session, or across GPS sessions if persistent is set to True.
This is different than setting instance properties through Python’s standard mechanism in that there is no guarantee that the same instance of GPS.File will be created for each physical file on the disk, and therefore you would not be able to associate a property with the physical file itself.
Parameters: |
|
---|
Displays in the dependency browser the list of files that depends on file_name. This command might take some time to execute since GPS needs. to parse the cross-reference information for multiple source files

This function is only available if GPS was compiled with support for pygobject and the latter was found at run time. It returns a widget that can be manipulated through the usual PyGtk functions. PyGObject is a binding to the gtk+ toolkit, and allows you to create your own windows easily, or manipulate the entire GPS GUI from Python.
Returns: | An instance of PyWidget |
---|
See also
# The following example makes the project view inactive. One could
# easily change the contents of the project view as well.
widget = GPS.MDI.get("Project View")

This class gives access to the help system of GPS as well as the integrated browser.
Adds a new directory to the GPS_DOC_PATH environment variable. This directory is searched for documentation files. If this directory contains a gps_index.xml file, it is parsed to find the list of documentation files to add to the Help menu. See the GPS documentation for more information on the format of the gps_index.xml files
Parameters: | directory – Directory containing the documentation |
---|
Opens the GPS HTML viewer, and loads the given URL. If anchor matches a <a> tag in this file, GPS jumps to it. If URL is not an absolute file name, it is searched in the path set by the environment variable GPS_DOC_PATH.
The URL can be a network file name, with the following general format:
protocol://username@host:port/full/path
where protocol is one of the recognized protocols (http, ftp,.. see the GPS documentation), and the username and port are optional.
Parameters: |
|
---|
See also
GPS.HTML.browse("gps.html")
=> will open the GPS documentation in the internal browser
GPS.HTML.browse("http://host.com/my/document")
=> will download documentation from the web
This class gives access to the external documentation for shell commands. This external documentation is stored in the file shell_commands.xml, part of the GPS installation, and is what you are currently seeing.
You almost never need to use this class yourself, since it is used implicitly by Python when you call the help(object) command at the GPS prompt.
The help browser understands the standard http urls, with links to specific parts of the document. For instance:
"http://remote.com/my_document"
or "#link"
As a special case, it also supports links starting with ‘%’. These are shell commands to execute within GPS, instead of a standard html file. For instance:
<a href="%shell:Editor.edit g-os_lib.ads">GNAT.OS_Lib%lt;/a%gt;
The first word after ‘%’ is the language of the shell command, the rest of the text is the command to execute
See also
Initializes the instance of the Help class. This parses the XML file that contains the description of all the commands. With python, the memory occupied by this XML tree will be automatically freed. However, with the GPS shell you need to explicitly call GPS.Help.reset().
See also
Returns the name of the file that contains the description of the shell commands. You should not have to access it yourself, since you can do so using GPS.Help().getdoc() instead.
Returns: | A string |
---|
See also
Searches in the XML file :file`shell_commands.xml` for the documentation for this specific command or entity. If no documentation is found, an error is raised. If html is true, the documentation is formated in HTML
Parameters: |
|
---|---|
Returns: | A string, containing the help for the command |
print GPS.Help().getdoc("GPS.Help.getdoc")
Help
Help.getdoc %1 "GPS.Help.getdoc"
Help.reset %2
Frees the memory occupied by this instance. This frees the XML tree that is kept in memory. As a result, you can no longer call GPS.Help.getdoc().
General interface to hooks. Hooks are commands executed when some specific events occur in GPS, and allow you to customize some of the aspects of GPS
See also
The available hooks are:

Hook after_character_added
Hook word_added
clipboard_changed(hookname)
Called when the contents of the clipboard has changed, either because the user has done a Copy or Cut operation, or because he called Paste Previous which changes the current entry in the multi-level clipboard.
commit_done_hook(hookname)
Called when a commit has been done.
compilation_finished(hookname, category, target_name, mode_name, status)
Called when a compile operation has finished.
Among the various tasks that GPS connects to this hook are the automatic reparsing of all xref information, and the activation of the automatic-error fixes
See also the hook “xref_updated”.
param category: | A string, the location/highlighting category that contains the compilation output. |
---|---|
param target_name: | |
A string, name of the executed build target. | |
param mode_name: | |
A string, name of the executed build mode. | |
param status: | An integer, exit status of the execuded program. |
compilation_starting(hookname, category, quiet, shadow)
Called when a compile operation is about to start.
Among the various tasks that GPS connects to this hook are: check whether unsaved editors should be saved (asking the user), and stop the background task that parses all xref info. If quiet is True, no visible modification should be done in the MDI, such as raising consoles or clearing their content, since the compilation should happen in background mode.
Funtions connected to this hook should return False if the compilation should not occur for some reason, True if it is OK to start the compilation. Typically, the reason to reject a compilation would be because the user has explicitly cancelled it through a graphical dialog, or because running a background compilation is not suitable at this time.
param category: | A string, the location/highlighting category that contains the compilation output. |
---|---|
param quiet: | A boolean, if True then the GUI should advertise the compilation, otherwise nothing should be reported to the user, unless there is an error. |
param shadow: | A boolean, indicates whether the build launched was a Shadow builds, ie a “secondary” build launched automatically by GPS after a “real” build. For instance, when the multiple toolchains mode is activated, the builds generating cross-references are Shadow builds. |
return: | A boolean |
# The following code adds a confirmation dialog to all
# compilation commands.
def on_compilation_started(hook, category, quiet, shadow):
if not quiet:
return MDI.yes_no_dialog("Confirm compilation ?")
else:
return True
Hook("compilation_starting").add(on_compilation_started)
# If you create a script to execute your own build script, you
# should always do the following as part of your script. This
# ensures a better integration in GPS (saving unsaved editors,
# reloading xref information automatically in the end, raising
# the GPS console, parsing error messages for automatically
# fixable errors,...)
if notHook ("compilation_starting").run_until_failure(
"Builder results", False, False):
return
# ... spawn your command
Hook("compilation_finished").run("Builder results")
compute_build_targets(hookname, name)
Called whenever GPS needs to compute a list of subtargets for a given build target. The handler should check whether name is a known build target, and if so, return a list of tuples, where each tuple corresponds to one target and contains a display name (used in the menus, for instance) and the name of the target. If name is not known, it should return an empty list.
param name: | A string, the target type |
---|---|
return: | A string |
def compute_targets(hook, name):
if name == "my_target":
return [(display_name_1, target_1),
(display_name_2, target_2)]
return ""
GPS.Hook("compute_build_targets").add(compute_targets)
context_changed(hookname, context)
Called when the current context changes in GPS, such a new file is selected or a new entity or window are created.
param context: | An instance of GPS.Context |
---|
contextual_menu_close(hookname)
Called just before a contextual menu is destroyed. At this time, the value returned by GPS.contextual_context() is still the one used in the hook contextual_menu_open and you can still reference the data you stored in the context. This hook is called even if no action was selected by the user. However, it is always called before the action is executed, since the menu itself is closed first.
See also
contextual_menu_open hook()
contextual_menu_open(hookname)
Called just before a contextual menu is created. It is called before any of the filters is evaluated, and can be used to precomputed data shared by multiple filters to speed up the computation. Use GPS.contextual_context() to get the context of the contextual menu and store precomputed data in it.
See also
contextual_menu_close hook()
debugger_breakpoints_changed(hookname, debugger)
Called when the list of breakpoints has been refreshed. This might occur whether or not the list has changed, but is a good time to refresh any view that might depend on an up-to-date list
param debugger: | An instance of GPS.Debugger |
---|
debugger_command_action_hook(hookname, debugger, command)
Called when the user types a command in the debugger console, or emits the console through the GPS.Debugger API. It gives you a chance to override the behavior for the command, or even define your own commands. Note that you must ensure that any debugger command you execute this way does finish with a prompt. The function should return the output of your custom command
param debugger: | An instance of GPS.Debugger |
---|---|
param command: | A string, the command the user wants to execute |
return: | A boolean |
## The following example implements a new gdb command, "hello". When
## the user types this command in the console, we end up executing
## "print A" instead. This can be used for instance to implement
## convenient macros
def debugger_commands(hook, debugger, command):
if command == "hello":
return 'A=' + debugger.send("print A", False)
else:
return ""
GPS.Hook("debugger_command_action_hook").add(debugger_commands)

Called when the file being debugged has changed
param debugger: | An instance of GPS.Debugger |
---|
debugger_process_stopped(hookname, debugger)
Called when the debugger has ran and has stopped, for example when hitting a breakpoint, or after a next command. If you need to know when the debugger just started processing a command, you can connect to the debugger_state_changed hook instead. Conceptually, you could connect to debugger_state_changed at all times instead of debugger_process_stopped and check when the state is now “idle”.
param debugger: | An instance of GPS.Debugger |
---|
See also
Hook debugger_state_changed
debugger_process_terminated(hookname, debugger)
Called when the program being debugged has terminated.
param debugger: | An instance of GPS.Debugger |
---|
debugger_question_action_hook(hookname, debugger, question)
Action hook called just before displaying an interactive dialog, when the debugger is asking a question to the user. This hook can be used to disable the dialog (and send the rreply directly to the debugger instead). It should return a non-empty string to pass to the debugger if the dialog should not be displayed. You cannot send commands to the debugger when inside this hook, since the debugger is blocked waiting for an answer.
param debugger: | An instance of GPS.Debugger |
---|---|
param question: | A string |
return: | A string |
def gps_question(hook, debugger, str):
return "1" ## Always choose choice 1
GPS.Hook("debugger_question_action_hook").add(gps_question)
debug=GPS.Debugger.get()
debug.send("print &foo")
debugger_started(hookname, debugger)
Called when a new debugger has been started.
param debugger: An instance of GPS.Debugger See also
Hook debugger_state_changed
debugger_state_changed(hookname, debugger, new_state)
Indicates a change in the status of the debugger: new_state can be one of “none” (the debugger is now terminated), “idle” (the debugger is now waiting for user input) or “busy” (the debugger is now processing a command, and the process is running). As opposed to debugger_process_stopped, this hook is called when the command is just starting its executing (hence the debugger is busy while this hook is called, unless the process immediately stopped).
This hook is also called when internal commands are sent to the debugger, and thus much more often than if it was just reacting to user input. It is therefore recommended that the callback does the minimal amount of work, possibly doing the rest of the work in an idle callback to be executed when GPS is no longer busy.
If the new state is “busy”, you cannot send additional commands to the debugger.
When the state is either “busy” or “idle”, GPS.Debugger.command will return the command that is about to be executed or the command that was just executed and just completed.
param debugger: | An instance of GPS.Debugger |
---|---|
param new_state: | |
A string |
debugger_terminated(hookname, debugger)
Called when the debugger session has been terminated. It is now recommended that you connect to the debugger_state_changed hook and test whether the new state is “none”.
param debugger: | An instance of GPS.Debugger |

file_changed_detected(hookname, file)
Called whenever GPS detects that an opened file changed on the disk. You can connect to this hook if you want to change the default behavior, which is asking if the user wants to reload the file. Your function should return 1 if the action is handled by the function, and return 0 if the default behavior is desired.

Definess a new hook. This hook can take any number of parameters: the default is none. The type and number of parameters is called the type of the hook and is described by the optional second parameter. The value of this parameter should be either the empty string for a hook that does not take any parameter. Or it could be one of the predefined types exported by GPS itself (see list_hook_types()). Finally, it could be the word “”generic”” if this is a new type of hook purely defined for this scripting language
Parameters: |
|
---|
Removes function_name from the list of functions executed when the hook is run. This is the reverse of GPS.Hook.add().
Parameters: | function_name – A subprogram, see the “Subprogram Parameters” section in the GPS documentation |
---|
See also
Runs the hook. Calls all the functions that attached to that hook, and returns the return value of the last callback (this depends on the type of the hook, most often this is always None). When the callbacks for this hook are expected to return a boolean, this command stops as soon as one the callbacks returns True.
Parameters: | args – Any number of parameters to pass to the hook. |
---|
Applies to hooks returning a boolean. Executes all functions attached to this hook until one returns False, in which case no further function is called. Returns the returned value of the last executed function.
Parameters: | args – Any number of parameters to pass to the hook. |
---|---|
Returns: | A boolean |
Applies to hooks returning a boolean. Executes all functions attached to this hook until one returns True, in which case no further function is called. This returns the returned value of the last executed function. This is mostly the same as GPS.Hook.run(), but makes the halt condition more explicit.
Parameters: | args – Any number of parameters to pass to the hook. |
---|---|
Returns: | A boolean |
An exception raised by GPS. Raised when calling a subprogram from the GPS module with an invalid argument type (passing an integer when a string is expected, for example).

General interface to the Locations view.
Adds a new entry to the Locations view. Nodes are created as needed for category or file. If highlight is specified as a non-empty string, the enter line is highlighted in the file with a color determined by that highlight category (see register_highlighting() for more information). length is the length of the highlighting; the default of 0 indicates the whole line should be highlighted
Parameters: |
|
---|
GPS.Editor.register_highlighting("My_Category", "blue")
GPS.Locations.add(category="Name in location window",
file=GPS.File("foo.c"),
line=320,
column=2,
message="message",
highlight="My_Category")
Dumps the contents of the Locations view to the specified file, in XML format.
Parameters: | file – A string |
---|
Returns the list of all categories currently displayed in the Locations view. These are the top-level nodes used to group information generally related to one command, such as the result of a compilation.
Returns: | A list of strings |
---|
See also
Returns the list of all file locations currently listed in the given category and file.
Parameters: |
|
---|---|
Returns: | A list of EditorLocation |
See also
Parses the contents of the string, which is supposedly the output of some tool, and adds the errors and warnings to the Locations view. A new category is created in the locations window if it does not exist. Preexisting contents for that category are not removed, see locations_remove_category().
The regular expression specifies how locations are recognized. By default, it matches file:line:column. The various indexes indicate the index of the opening parenthesis that contains the relevant information in the regular expression. Set it to 0 if that information is not available. style_index and warning_index, if they match, force the error message in a specific category.
highlight_category, style_category and warning_category reference the colors to use in the editor to highlight the messages when the regexp has matched. If they are set to the empty string, no highlighting is done in the editor. The default values match those by GPS itself to highlight the error messages. Create these categories with GPS.Editor.register_highlighting().
Parameters: |
|
---|
See also
Removes a category from the Locations view. This removes all associated files.
Parameters: | category – A string |
---|
See also
Sets desired sorting order for file nodes of the category. Actual sort order can be overrided by user.
Parameters: | category – A string (“Chronological” or “Alphabetical”) |

This class provides an interface to the GPS logging mechanism. This can be used when debugging scripts, or even be left in production scripts for post-mortem analysis for instance. All output through this class is done in the GPS log file, $HOME/.gps/log.
GPS comes with some predefined logging streams, which can be used to configure the format of the log file, such as whether colors should be used or whether timestamps should be logged with each message.
Whether this logging stream is active
Creates a new logging stream. Each stream is associated with a name, which is displayed before each line in the GPS log file, and is used to distinguish between various parts of GPS. Calling this constructor with the same name multiple times creates a new class instance.
Parameters: | name – A string |
---|
log = GPS.Logger("my_script")
log.log("A message")
If condition is False, error_message is logged in the log file. If True, success_message is logged if present.
Parameters: |
|
---|
log=GPS.Logger("my_script")
log.check(1 == 2, "Invalid operation")
Logs a message in the GPS log file.
Parameters: | message – A string |
---|
Activates or deactivates a logging stream. The default for a sttream depends on the file $HOME/.gps/traces.cfg, and will generally be active. When a stream is inactive, no message is sent to the log file.
Use self.active to test whether a log stream is active.
Parameters: | active – A boolean |

If you have installed the pygobject package (see GPS’s documentation}, GPS will export a few more functions to Python so that it is easier to interact with GPS itself. In particular, the GPS.MDI.add() function allows you to put a widget created by pygobject under control of GPS’s MDI, so users can interact with it as with all other GPS windows.
import GPS
## The following line is the usual way to make pygobject visible
from gi.repository import Gtk, GLib, Gdk, GObject
def on_clicked(*args):
GPS.Console().write("button was pressed\n")
def create():
button=Gtk.Button('press')
button.connect('clicked', on_clicked)
GPS.MDI.add(button, "From testgtk", "testgtk")
win = GPS.MDI.get('testgtk')
win.split()
create()
This function is only available if pygobject could be loaded in the python shell. You must install this library first, see the documentation for GPS.MDI itself.
This function adds a widget inside the MDI of GPS. The resulting window can be manipulated by the user like any other standard GPS window. For example, it can be split, floated, or resized. title is the string used in the title bar of the window, short is the string used in the notebook tabs. You can immediately retrieve a handle to the created window by calling GPS.MDI.get (short).
This function has no effect if the widget is already in the MDI. In particular, the save_desktop parameter will not be taken into account in such a case.
Parameters: |
|
---|---|
Returns: | The instance of GPS.MDIWindow that was created |
from gi.repository import Gtk
b = Gtk.Button("Press Me")
GPS.MDI.add(b)
Returns all the windows currently in the MDI.
Returns: | A list of GPS.MDIWindow |
---|
Returns the window that currently has the focus, or raises an error if there is none.
Returns: | An instance of GPS.MDIWindow |
---|
Displays a modal dialog to report information to a user. This blocks the interpreter until the dialog is closed.
Parameters: | msg – A string |
---|
Displays a modal file selector. The user selected file is returned, or a file with an empty name if Cancel is pressed.
A file filter can be defined (such as “*.ads”) to show only a category of files.
Parameters: | file_filter – A string |
---|---|
Returns: | An instance of GPS.File |
Returns the window whose name is name. If there is no such window, None is returned.
Parameters: | name – A string |
---|---|
Returns: | An instance of GPS.MDIWindow |
Returns the window that contains child or raises an error if there is none.
Parameters: | child – An instance of GPS.GUI |
---|---|
Returns: | An instance of GPS.MDIWindow |
Hides the graphical interface of GPS.
Displays a modal dialog and requests some input from the user. The message is displayed at the top and one input field is displayed for each remaining argument. The arguments can take the form “”label=value””, in which case “”value”” is used as default for this entry. If argument is prepend with ‘multiline:’ prefix field is edited as multi-line text. The return value is the value that the user has input for each of these parameters.
An empty list is returned if the user presses Cancel.
Parameters: |
|
---|---|
Returns: | A list of strings |
a, b = GPS.MDI.input_dialog("Please enter values", "a", "b")
print a, b
Saves all currently unsaved windows. This includes open editors, the project, and any other window that has registered some save callbacks.
If force is false, a confirmation dialog is displayed so the user can select which windows to save.
Parameters: | force – A boolean |
---|
Shows the graphical interface of GPS.
Displays a modal dialog to ask a question to the user. This blocks the interpreter until the dialog is closed. The dialog has two buttons Yes and No, and the selected button is returned to the caller.
Parameters: | msg – A string |
---|---|
Returns: | A boolean |
if GPS.MDI.yes_no_dialog("Do you want to print?"):
print "You pressed yes"
This class represents one of the windows currently displayed in GPS. This includes both the windows currently visible to the user, and the ones that are temporarily hidden, for instance because they are displayed below another window. Windows acts as containers for other widgets.

This",height=0.25,shape=box,fontsize=10]; "GPS.GUI" -> "GPS.MDIWindow" [arrowsize=0.5,style="setlinewidth(0.5)"]; }
Prevents the creation of instances of GPS.MDIWindow. This is done by calling the various subprograms in the GPS.MDI class.
Floats the window, i.e., creates a new toplevel window to display it. It is then under control of the user’s operating system or window manager. If float is False, the window is reintegrated within the GPS MDI instead.
Parameters: | float – A boolean |
---|
Returns the child contained in the window. The returned value might be an instance of a subclass of GPS.GUI, if that window was created from a shell command.
Returns: | An instance of GPS.GUI |
---|
# Accessing the GPS.Console instance used for python can be done
# with:
GPS.MDI.get("Python").get_child()
Returns True if the window is currently floating (i.e., in its own toplevel window) or False if the window is integrated into the main GPS window.
Returns: | A boolean |
---|
Returns the name of the window. If short is False, the long name is returned, the one that appears in the title bar. If True, the short name is returned, the one that appears in notebook tabs.
Parameters: | short – A boolean |
---|---|
Returns: | A string |
Returns the next window in the MDI, or the current window if there is no other window. If visible_only is True, only the windows currently visible to the user can be returned. This always returns floating windows.
Parameters: | visible_only – A boolean |
---|---|
Returns: | An instance of GPS.MDIWindow |
Raises the window so that it becomes visible to the user. The window also gains the focus.
Changes the title used for a window. name is the long title, as it appears in the title bar, and short, if specified, is the name that appears in notebook tabs.
Using this function may be dangereous in some contexts, since GPS keeps track of editors through their name.
Parameters: |
|
---|
Splits the window in two parts, either horizontally (side by side), or vertically (one below the other). If reuse is True, attempt to reuse an existing space rather than splitting the current window. This should be done to avoid ending up with too small windows.
Parameters: |
|
---|

GPS.MDIWindow.single()
This class is used to manipulate GPS messages: build errors, editor annotations, etc.
The flags returned by GPS.Message.get_flags().
Adds a Message in GPS.
Parameters: |
|
---|
# Create a message
m=GPS.Message("default", GPS.File("gps-main.adb"),
1841, 20, "test message", 0)
# Remove the message
m.remove()
If the message has an associated action, executesa it.
Returns the message’s category.
Returns the message’s column.
Returns the message’s file.
Returns an integer representing the location of the message: should it be displayed in locations view and source editor’s sidebar. Message is displayed in source editor’s sidebar when zero bit is set, and is displayed in locations view when first bit is set, so here is possible values:
Note, this set of flags can be extended in the future, so they should be viewed as bits that are “or”ed together.
Returns the message’s line.
Returns an EditorMark which was created with the message and keeps track of the location when the file is edited.
Returns the message’s text.
Returns a list of all messages currently stored in GPS.
Parameters: |
|
---|---|
Returns: | a list of GMS.Message |
Removes the message from GPS.
Adds an action item to the message. This adds an icon to the message; Clicking on the icon executes action.
Parameters: |
|
---|
Sets default sorting method for files in the Locations view.
Parameters: |
|
---|
Sets the style of the message. len is the length in number of characters to highlight. If 0, highlight the whole line. If omitted, the length of the message highlighting is not modified.
Parameters: |
|
---|
Adds an action item to the message. This adds an icon to the message. Clicking on this icon calls subprogram, with the message passed as its parameter.
Parameters: |
|
---|
# This adds a "close" button to all the messages
[msg.set_subprogram(lambda m : m.remove(), "gtk-close", "")
for msg in GPS.Message.list()]

This class is used to handle user-defined tool output parsers. Parsers are organized in chains. Output of one parser is passed as input to next one. Chains of parser could be attached to a build target. This class is for internal use only. Instead users should inherit custom parser from OutputParser defined in tool_output.py, but their methods match.
# Here is an example of custom parser:
#
import GPS, tool_output
class PopupParser(tool_output.OutputParser):
def on_stdout(self,text,command):
GPS.MDI.dialog (text)
if self.child != None:
self.child.on_stdout (text,command)
You can attach custom parser to a build target by specifying it in an XML file.
<target model="myTarget" category="_Run" name="My Target">
<output-parsers>[default] popupparser</output-parsers>
</target>
Where [default] abbreviates names of all parsers predefined in GPS.
Creates a new parser and initialize its child reference, if provided.
Called when all output is parsed to flush any buffered data at end of the stream.
Like on_stdout(), but for the error stream.
Called each time a portion of output text is ready to parse. Takes the portion of text as a parameter and passes filtered portion to its child.
Interface to the GPS preferences, as set in the Edit ‣ Preferences dialog. New preferences are created through XML customization files (or calls to GPS.parse_xml(), see the GPS documentation).
See also
GPS.parse_xml('''
<preference name="custom-adb-file-color"
label="Background color for .adb files"
page="Editor:Fonts & Colors"
default="yellow"
type="color" />''')
print "color is " + GPS.Preference("custom-adb-file-color").get()
Initializes an instance of the GPS.Preference class, associating it with the preference name, which is the one that is found in the $HOME/.gps/preferences file. When you are creating a new preference, this name can include ‘/’ characters, which results in subpages created in the Preferences dialog. The name after the last ‘/’ should only include letters and ‘-‘ characters. If the name starts with ‘/’ and contains no other ‘/’, the preference is not visible in the Preferences dialog, though it can be manipulated as usual and is loaded automatically by GPS on startup.
Parameters: | name – A string |
---|
Creates a new preference and makes it visible in the preferences dialog. In the dialog, the preference appears in the page given by the name used when creating the instance of GPS.Preference. label qualifies the preference and doc appears as a tooltip to explain the preference to users. type describes the type of preference and therefore how it should be edited by users.
The parameters to this function cannot be named (since it uses a avariable number of parameters, see the documentation below).
The additional parameters depend on the type of preference you are creating:
Parameters: |
|
---|
Creates a new text style preference, which enables the user to choose between different text style characteristics, namely foreground color, background color, and wether the text is bold, italic, both, or neither.
Parameters: |
|
---|
Gets value of the given preference. The exact returned type depends on the type of the preference. Note that boolean values are returned as integers, for compatibility with older versions of Python.
Returns: | A string or an integer |
---|
if GPS.Preference("MDI-All-Floating"):
print "We are in all-floating mode"
Sets value for the given preference. The type of the parameter depends on the type of the preference.
Parameters: |
|
---|
Interface to expect-related commands. This class can be used to spawn new processes and communicate with them later. It is similar to what GPS uses to communicate with gdb. This is a subclass of GPS.Command.
# The following example launches a gdb process, lets it print its
# welcome message, and kills it as soon as a prompt is seen in the
# output. In addition, it displays debugging messages in a new GPS
# window. As you might note, some instance-specific data is stored in
# the instance of the process, and can be retrieve in each callback.
import GPS, sys
def my_print(msg):
sys.stdout.set_console("My gdb")
print(msg)
sys.stdout.set_console()
def on_match(self, matched, unmatched):
my_print "on_match (" + self.id + ")=" + matched
self.kill()
def on_exit(self, status, remaining_output):
my_print "on_exit (" + self.id + ")"
def run():
proc = GPS.Process("gdb", "^\(gdb\)", on_match=on_match,
on_exit=on_exit)
proc.id = "first session"
run()
# A similar example can be implemented by using a new class. This is
# slightly cleaner, since it does not pollute the global namespace.
class My_Gdb(GPS.Process):
def matched(self, matched, unmatched):
my_print("matched " + self.id)
self.kill()
def exited(self, status, output):
my_print("exited " + self.id)

Spawns command, which can include triple-quoted strings, similar to Python, which are always preserved as one argument.
If regexp is not-empty and on_match_action is specified, launch on_match_action when regexp is found in the process output. If on_exit_action is specified, execute it when the process terminates. Return the ID of the spawned process.
regexp is always compiled with the multi_line option, so “^” and “$” also match at the beginning and end of each line, not just the whole output. You can optionally compile it with the single_line option whereby ”.” also matches the newline character. Likewise you can set the regexp to be case insensitive by setting case_sensitive_regexp to False.
on_match is a subprogram called with the parameters:
before_kill is a subprogram called just before the process is about to be killed. It is called when the user is interrupting the process through the task manager, or when GPS exits. It is not called when the process terminates normally. When it is called, the process is still valid and can be send commands. Its parameters are:
on_exit is a subprogram called when the process has exited. You can no longer send input to it at this stage. Its parameters are:
$1 = the instance of GPS.Process
$2 = the exit status
$3 = the output of the process since the last call to on_match()
If task_manager is True, the process will be visible in the GPS task manager and can be interrupted or paused by users. Otherwise, it is running in the background and never visible to the user. If progress_regexp is specified, the output of the process will be scanned for this regexp. The part that matches will not be returned to on_match. Instead, they will be used to guess the current progress of the command. Two groups of parenthesis are parsed, the one at progress_current, and the one at progress_total. The number returned for each of these groups indicate the current progress of the command and the total that must be reached for this command to complete. For example, if your process outputs lines like “done 2 out of 5”, you should create a regular expression that matches the 2 and the 5 to guess the current progress. As a result, a progress bar is displayed in the task manager of GPS, and will allow users to monitor commands.
remote_server represents the server used to spawn the process. By default, the GPS_Server is used, which is always the local machine. See the section “Using GPS for Remote Development” in the GPS documentation for more information on this field.
If show_command is set, the command line used to spawn the new process is displayed in the Messages console.
If strip_cr is true, the output of the process will have all its ASCII.CR removed before the string is passed to GPS and your script. This, in general, provides better portability to Windows systems, but might not be suitable for applications for which CR is relevant (for example, those that drive an ANSI terminal).
An exception is raised if the process could not be spawned.

Blocks execution of the script until either regexp has been seen in the output of the command or timeout has expired. If timeout is negative, wait forever until we see regexp or the process completes execution.
While in such a call, the usual on_match callback is called as usual, so you might need to add an explicit test in your on_match callback not to do anything in this case.
This command returns the output of the process since the start of the call and up to the end of the text that matched regexp. Note that it also includes the output sent to the on_match callback while it is running. It does not, however, include output already returned by a previous call to this function (nor does it guarantee that two successive calls return the full output of the process, since some output might have been matched by on_match between the two calls, and would not be returned by the second call).
If a timeout occurred or the process terminated, an exception is raised.
Parameters: |
|
---|---|
Returns: | A string |
proc = GPS.Process("/bin/sh")
print("Output till prompt=" + proc.expect (">"))
proc.send("ls")
Waits untill the process terminates and returns its output. This is the output since the last call to this function, so if you call it after performing some calls to expect(), the returned string does not contain the output already returned by expect().
Returns: | A string |
---|
Interrupts a process controlled by GPS.
Terminates a process controlled by GPS.
Sends a line of text to the process. If you need to close the input stream to an external process, it often works to send the character ASCII 4, for example through the Python command chr(4).
Parameters: |
|
---|
Tells the process about the size of its terminal. rows and columns should (but need not) be the number of visible rows and columns of the terminal in which the process is running.
Parameters: |
|
---|
Blocks the execution of the script until the process has finished executing. The exit callback registered when the process was started will be called before returning from this function.
This function returns the exit status of the command.
Returns: | An integer |
---|
Represents a project file. Also see the GPS documentation on how to create new project attributes.
See also
Related hooks:
project_view_changed
Called whenever the project is recomputed, such as when one of its attributes was changed by the user or the environment variables are changed.
This is a good time to test the list of languages (GPS.Project.languages()) that the project supports and do language-specific customizations
project_changed
Called when a new project was loaded. The hook above is called after this one.
Initializes an instance of GPS.Project. The project must be currently loaded in GPS.
Parameters: | name – The project name |
---|
See also
Adds some values to an attribute. You can add as many values you need at the end of the param list. If the package is not specified, the attribute at the toplevel of the project is queried. The index only needs to be specified if it applies to that attribute.
Parameters: |
|
---|
For example:
GPS.Project.root().add_attribute_values(
"Default_Switches", "Compiler", "ada", "-gnatwa", "-gnatwe");
Adds a new dependency from self to the project file pointed to by path. This is the equivalent of putting a with clause in self, and means that the source files in self can depend on source files from the imported project.
Parameters: | path – The path to another project to depend on |
---|
See also
Adds some main units to the current project for the current scenario. The project is not saved automatically.
Parameters: | args – Any number of arguments, at least one |
---|
Adds some predefined directories to the source path or the objects path. These are searched when GPS needs to open a file by its base name, in particular from the File ‣ Open From Project dialog. The new paths are added in front, so they have priorities over previously defined paths.
Parameters: |
|
---|
GPS.Project.add_predefined_paths(os.pathsep.join(sys.path))
Adds a new source directory to the project. The new directory is added in front of the source path. You should call GPS.Project.recompute() after calling this method to recompute the list of source files. The directory is added for the current value of the scenario variables only. Note that if the current source directory for the project is not specified explicitly in the .gpr file), it is overriden by the new directory you are adding. If the directory is already part of the source directories for the project, it is not added a second time.
Parameters: | directory – A string |
---|
Returns the list of projects that might contain sources that depend on the project’s sources. When doing extensive searches it is not worth checking other projects. Project itself is included in the list.
This is also the list of projects that import self.
Returns: | A list of instances of GPS.Project |
---|
for p in GPS.Project("kernel").ancestor_deps():
print p.name()
# will print the name of all the projects that import kernel.gpr
Clears the values list of an attribute.
If the package is not specified, the attribute at the toplevel of the project is queried.
The index only needs to be specified if it applies to that attribute.
Parameters: |

---|
Returns the list of projects on which self depends (either directly if recursive is False, or including indirect dependencies if True).
Parameters: | recursive – A boolean |
---|---|
Returns: | A list of GPS.Project instances |

Fetches the value of the attribute in the project.
If package is not specified, the attribute at the toplevel of the project is queried.
index only needs to be specified if it applies to that attribute.
If the attribute value is stored as a simple string, a list with a single element is returned. This function always returns the value of the attribute in the currently selected scenario.
Parameters: |
|

Returns: | A list of strings |
# If the project file contains the following text:
#
# project Default is
# for Exec_Dir use "exec/";
# package Compiler is
# for Switches ("file.adb") use ("-c", "-g");
# end Compiler;
# end Default;
# Then the following commands;
a = GPS.Project("default").get_attribute_as_list("exec_dir")
=> a = ("exec/")
b = GPS.Project("default").get_attribute_as_list(
"switches", package="compiler", index="file.adb")
=> b = ("-c", "-g")
Fetches the value of the attribute in the project.
If package is not specified, the attribute at the toplevel of the project is queried.
index only needs to be specified if it applies to that attribute.
If the attribute value is stored as a list, the result string is a concatenation of all the elements of the list. This function always returns the value of the attribute in the currently selected scenario.
When the attribute is not explicitely overridden in the project, the default value is returned. This default value is the one described in an XML file (see the GPS documentation for more information). This default value is not necessarily valid, and could for instance be a string starting with a parenthesis, as explained in the GPS documentation.
Parameters: |
|
---|---|
Returns: | A string, the value of this attribute |
# If the project file contains the following text:
# project Default is

Loads a new project, which replaces the current root project, and returns a handle to it. All imported projects are also loaded at the same time. If the project is not found, a default project is loaded.
If force is True, the user will not be asked whether to save the current project, whether it was modified or not.
If keep_desktop is False, load the saved desktop configuration, otherwise keep the current one.
Parameters: |
|
---|---|
Returns: | An instance of GPS.Project |
Returns the name of the project. This does not include directory information; use self.file().name() if you want to access that information.
Returns: | A string, the name of the project |
---|
Returns the list of object directories for this project. If recursive is True, the source directories of imported projects is also returned. There might be duplicate directories in the returned list.
Parameters: | recursive – A boolean |
---|---|
Returns: | A list of strings |
Launches a graphical properties editor for the project.
Recomputes the contents of a project, including the list of source files that are automatically loaded from the source directories. The project file is not reloaded from the disk and this should only be used if you have created new source files outside of GPS.
GPS.Project.recompute()
Removes specific values from an attribute. You can specify as many values you need at the end of the param list.
If package is not specified, the attribute at the toplevel of the project is queried.
index only needs to be specified if it applies to that attribute.
Parameters: |

---|
For example:
GPS.Project.root().remove_attribute_values(
"Default_Switches", "Compiler", "ada", "-gnatwa", "-gnatwe");
Removes a dependency between two projects. You must call GPS.Project.recompute() once you are done doing all the modifications on the projects.
Parameters: | imported – An instance of GPS.Project |
---|
See also
Removes a property associated with a project.
Parameters: | name – A string |
---|

Returns the list of scenario variables for the current project hierarchy and their current values. These variables are visible at the top of the Project view in the GPS window. The initial value for these variables is set from the environment variables’ value when GPS is started. However, changing the value of the environment variable later does not change the value of the scenario variable.
Returns: | hash table associating variable names and values |
---|
See also
For example:
GPS.Project.scenario_variables()["foo"]
=> returns the current value for the variable foo
Returns a concatenation of VARIABLE=VALUE, each preceded by prefix. This string is generally used when calling external tools, for example, make or GNAT.
Parameters: | prefix – String to print before each variable in the output |
---|---|
Returns: | a string |
# The following GPS action can be defined in an XML file, and will
# launch the make command with the appropriate setup for the
# environment
# variables:
# <action name="launch make"> \
# <shell lang="python">GPS.scenario_variables_cmd_line()</shell> \
# <external>make %1</external> \
# </action>
Returns a hash table where keys are the various scenario variables defined in the current project and values the different values that this variable can accept.
Returns: | A hash table of strings |
---|
Returns the list of matches for pattern in all the files belonging to the project (and its imported projects if recursive is true (default). scope is a string, and should be any of ‘whole’, ‘comments’, ‘strings’, ‘code’. The latter will match only for text outside of comments.
Parameters: |
|
---|---|
Returns: | A list of GPS.FileLocation instances |
Sets the value of an attribute. The attribute has to be stored as a single value. If package is not specified, the attribute at the toplevel of the project is queried. index only needs to be specified if it applies to that attribute.
Parameters: |
|
---|
Associates a string property with the project. This property is retrievable during the whole GPS session, or across GPS sessions if persistent is set to True.
This is different than setting instance properties through Python’s standard mechanism in that there is no guarantee that the same instance of GPS.Project is created for each physical project on the disk and therefore you would not be able to associate a property with the physical project itself.
Parameters: |
|
---|
Changes the value of a scenario variable. You need to call GPS.Project.recompute() to activate this change (so that multiple changes to the project can be grouped.
Parameters: |
|
---|

Returns the list of source directories for this project. If recursive is True, the source directories of imported projects is also returned. There might be duplicate directories in the returned list.
Parameters: | recursive – A boolean |
---|---|
Returns: | A list of strings |
See also
Returns the list of source files for this project. If recursive is true, all sources from imported projects are also returned. Otherwise, only the direct sources are returned. The basenames of the returned files are always unique: not two files with the same basenames are returned, and the one returned is the first one see while traversing the project hierarchy.
Parameters: | recursive – A boolean |
---|---|
Returns: | A list of instances of GPS.File |
Updates the cross-reference information in memory for all files of the project. This does not regenerate that information, just read all the .ali files found in the object directory of the project (and all imported projects if recursive is True). For efficiency purpose, this should generally be called before calling GPS.freeze_xref().
Parameters: | recursive – A boolean |

This class is used to manipulate GPS Project Templates.
This is the type of the commands returned by the references extractor.

This class provides an interface to the search facilities used for the GPS omni-search. In particular, this allows you to search file names, sources, and actions, etc.
This class provides facilities exported directly by Ada, so you can for example look for file names by writting:
s = GPS.Search.lookup(GPS.Search.FILE_NAMES)
s.set_pattern("search", flags=GPS.Search.FUZZY)
while True:
(has_next, result) = s.get()
if result:
print result.short
if not has_next:
break
However, one of the mandatory GPS plugins augments this base class with high-level constructs such as iterators and now you can write code as:
for result in GPS.Search.search(
GPS.Search.FILE_NAMES, "search", GPS.Search.FUZZY):
print result.short
Iterations are meant to be done in the background, so they are split into small units.
It is possible to create your own search providers (which would be fully included in the omni-search of GPS) by subclassing this class, as in:
class MySearchResult(GPS.Search_Result):
def __init__(self, str):
self.short = str
self.long = "Long description: %s" % str
def show(self):
print "Showing a search result: '%s'" % self.short
class MySearchProvider(GPS.Search):
def __init__(self):
# Override default so that we can build instances of our
# class
pass
def set_pattern(self, pattern, flags):
self.pattern = pattern
self.flags = flags
self.current = 0
def get(self):
if self.current == 3:
return (False, None) # no more matches
self.current += 1
return (
True, # might have more matches
MySearchResult(
"<b>match</b> %d for '%s' (flags=%d)"
% (self.current, self.pattern, self.flags)
)
)
GPS.Search.register("MySearch", MySearchProvider())
The various contexts in which a search can occur.
The various types of search, similar to what GPS provides in its omni-search.
Flags to configure the search, that can be combined with the above.
Always raises an exception; use GPS.Search.lookup() to retrieve an instance.
Returns the next occurrence of the pattern.
Returns: | a tuple containing two elements; the first element is a boolean that indicates whether there might be further results; the second element is either None or an instance of GPS.Search_Result. It might be set even if the first element is False. On the other hand, it might be None even if there might be further results, since the search itself is split into small units. For instance, when searching in sources, each source file will be parsed independently. If a file does not contain a match, next() will return a tuple that contains True (there might be matches in other files) and None (there were no match found in the current file) |
---|
Looks up one of the existing search factories.
Parameters: | name – a string, one of, e.g., GPS.Search.FILE_NAMES, GPS.Search.SOURCES |
---|
Results the next non-null result. This might take longer than get(), since it keeps looking until it actually finds a new result. It raises StopIteration when there are no more results.
Registers a new custom search. This will be available to users via the omni-search in GPS, or via the GPS.Search class.
Parameters: |
|
---|
A high-level wrapper around lookup and set_pattern to make Python code more readable (see general documentation for GPS.Search).
Parameters: |
|
---|
Sets the search pattern.
Parameters: |
|
---|
A class that represents the results found by GPS.Search.
A long version of the description. For instance, when looking in sources it might contain the full line that matches
The short description of the result
x.__init__(...) initializes x; see help(type(x)) for signature
Executes the action associated with the result. This action depends on where you were searching. For example, search in file names would as a result open the corresponding file; searching in bookmarks would jump to the corresponding location; search in actions would execute the corresponding action.
This class is used to manipulate GPS Styles, which are used, for example, to represent graphical attributes given to Messages.
This class is fairly low-level, and we recommend using the class gps_utils.highlighter.OverlayStyle() instead. That class provides similar support for specifying attributes, but makes it easier to highlight sections of an editor with that style, or to remove the highlighting.
Creates a style.
Parameters: |
|
---|
# Create a new style
s=GPS.Style("my new style")
# Set the background color to yellow
s.set_background("#ffff00")
# Apply the style to all the messages
[m.set_style(s) for m in GPS.Message.list()]
Returns: | a string, background of the style |
---|
Returns: | a string, foreground of the style |
---|
Returns a Boolean indicating whether this style is shown in the speedbar.
Returns: | a boolean |
---|

## Execute callback three times and remove it
import GPS;
def callback(timeout):
timeout.occur += 1
print "A timeout occur=" + `timeout.occur`
if timeout.occur == 3:
timeout.remove()
t = GPS.Timeout(500, callback)
t.occur = 0
A timeout object executes a specific action repeatedly, at a specified interval, as long as it is registered. The action takes a single argument, the instance of GPS.Timeout that called it.

Parameters: |
|
---|
b = GPS.ToolButton("gtk-new", "New File",
lambda x : GPS.execute_action("/File/New"))
GPS.Toolbar().insert(b, 0)
Interface to commands related to the toolbar. This allows you to add new combo boxes to the GPS toolbars. Note that this can also be done through XML files, see the GPS documentation.
See also
import GPS
def on_changed(entry, choice):
print "changed " + choice + ' ' + entry.custom
def on_selected(entry, choice):
print "on_selected " + choice + ' ' + entry.custom
ent = GPS.Combo("foo", label="Foo", on_changed=on_changed)
GPS.Toolbar().append(ent, tooltip => "What it does")
ent.custom = "Foo" ## Create any field you want
ent.add(choice="Choice1", on_selected=on_selected)
ent.add(choice="Choice2", on_selected=on_selected)
ent.add(choice="Choice3", on_selected=on_selected)
It is easier to use this interface through XML customization files, see the GPS documentation. However, this can also be done through standard GPS shell commands:
Combo "foo" "Foo" "on_changed_action"
Toolbar
Toolbar.append %1 %2 "What it does"
Toolbar
Toolbar.get %1 "foo"
Combo.add %1 "Choice1" "on_selected"action"

Initializes a new instance of the toolbar, associated with the default toolbar of GPS. This is called implicitly from Python.
Adds a new widget in the toolbar. This can be an instance of GPS.Combo, GPS.Button, or GPS.ToolButton.
Parameters: |
|
---|
Returns the toolbar entry matching id. Raises an error if no such entry exists. The same instance of GPS.Combo is always returned for each id, so you can store your own fields in this instance and access it later.
Parameters: | id – A string, the name of the entry to get |
---|---|
Returns: | An instance of GPS.Combo |
ent = GPS.Combo("foo")
GPS.Toolbar().append(ent)
ent.my_custom_field = "Whatever"
print GPS.Toolbar().get("foo").my_custom_field
=> "Whatever"
Returns the position-th widget in the toolbar. If the widget was created from a scripting language, its instance is returned. Otherwise, a generic instance of GPS.GUI is returned. This can be used to remove some items from the toolbar, for example.
Parameters: | position – An integer, starting at 0 |
---|---|
Returns: | An instance of a child of GPS.GUI |
GPS.Toolbar().get_by_pos(0).set_sensitive(False)
# can be used to gray out the first item in the toolbar
Adds a new widget in the toolbar. This can be an instance of GPS.Combo, GPS.Button, or GPS.ToolButton.
Parameters: |
|
---|
An exception raised by GPS. It indicates an internal error in GPS, raised by the Ada code itself. This exception is unexpected and indicates a bug in GPS itself, not in the Python script, although it might be possible to modify the latter to work around the issue.

---|
This class provides access to the graphical comparison between two or three files or two versions of the same file within GPS. A visual diff is a group of two or three editors with synchronized scrolling. Differences are rendered using blank lines and color highlighting.
This function prevents the creation of a visual diff instance directly. You must use GPS.Vdiff.create() or GPS.Vdiff.get() instead.
Closes all editors involved in a visual diff.
If none of the files given as parameter is already used in a visual diff, creates a new visual diff and returns it. Otherwise, None is returned.
Parameters: | |
---|---|
Returns: | An instance of GPS.Vdiff |
Returns the list of files used in a visual diff.
Returns: | A list of GPS.File |
---|
Returns an instance of an already exisiting visual diff. If an instance already exists for this visual diff, it is returned. All files passed as parameters must be part of the visual diff but not all files of the visual diff must be passed for the visual diff to be returned. For example if only one file is passed, the visual diff that contains it, if any, is returned even if it is a two or three file visual diff.
Parameters: |
---|
Returns the list of visual diffs currently opened in GPS.
Returns: | A list GPS.Vdiff |
---|
# Here is an example that demonstrates how to use GPS.Vdiff.list to
# close all the visual diff.
# First two visual diff are created
vdiff1 = GPS.Vdiff.create(GPS.File("a.adb"), GPS.File("b.adb"))
vdiff2 = GPS.Vdiff.create(GPS.File("a.adb"), GPS.File("b.adb"))
# Then we get the list of all current visual diff
vdiff_list = GPS.Vdiff.list()
# And we iterate on that list in order to close all editors used in
# each visual diff from the list.
for vdiff in vdiff_list:
files = vdiff.files()
# But before each visual diff is actually closed, we just inform
# the user of the files that will be closed.
for file in files:
print "Beware! " + file.name () + "will be closed."
# Finally, we close the visual diff
vdiff.close_editors()
Recomputes a visual diff. The content of each editor used in the visual diff is saved. The files are recompared and the display is redone (blank lines and color highlighting).
This class represents Tree-based views for XML files.
Creates a new XMLViewer, named name.
columns is the number of columns that the table representation should have. The first column is always the one used for sorting the table.
parser is a subprogram called for each XML node that is parsed. It takes three arguments: the name of the XML node being visited, its attributes (in the form “attr=’foo’ attr=”bar””), and the text value of that node. This subprogram should return a list of strings, one per visible column create for the table. Each element will be put in the corresponding column.
If parser is not specified, the default is to display in the first column the tag name, in the second column the list of attributes, and in the third column when it exists the textual contents of the node.
on_click is an optional subprogram called every time the user double-clicks on a line, and is passed the same arguments as parser. It has no return value.
on_select has the same profile as on_click, but is called when the user has selected a new line, not double-clicked on it.
If sorted is True, the resulting graphical list is sorted on the first column.
Parameters: |
|

# Display a very simply tree. If you click on the file name,
# the file will be edited.
