The http://www.cs.virginia.edu/zephyr Abstract Syntax Description Lanuguage (ASDL) is a language designed to describe the tree-like data structures in compilers. Its main goal is to provide a method for compiler components written in different languages to interoperate. ASDL makes it easier for applications written in a variety of programming languages to communicate complex recursive data structures.
asdlGen
is a tool that takes ASDL descriptions and produces
implementations of those descriptions in a variety of popular
languages. ASDL and asdlGen
together provide the following advantages
ASDL descriptions describe the tree-like data structures such as
abstract syntax trees (ASTs) and compiler intermediate representations
(IRs). Tools such as asdlGen
automatically produce the equivalent
data structure definitions for C, C++, Java, Standard ML, and Haskell.
asdlGen
also produces functions for each language that read and
write the data structures to and from a platform and language
independent sequence of bytes. The sequence of bytes is called a
pickle.
ASDL pickles can be interactively viewed and edited with a graphical
http://www.cs.princeton.edu/zephyr/browser, or pretty printed into a
simple textual format. The browser provides some advanced features
such as display styles and tree based versions of standard unix tools
such as diff
and grep
. ASDL is part of the Zephyr http://www.cs.virginia.edu/nci project.
