class RuboCop::TargetFinder
This class finds target files to inspect by scanning the directory tree and picking ruby files.

Generate a list of target files by expanding globbing patterns (if any). If args is empty, recursively find all Ruby source files under the current directory @return [Array] array of file paths
# File lib/rubocop/target_finder.rb, line 30 def find(args) return target_files_in_dir if args.empty? files = [] args.uniq.each do |arg| files += if File.directory?(arg) target_files_in_dir(arg.chomp(File::SEPARATOR)) else process_explicit_path(arg) end end files.map { |f| File.expand_path(f) }.uniq end
Search for files recursively starting at the given base directory using the given flags that determine how the match is made. Excluded files will be removed later by the caller, but as an optimization #find_files removes the top level directories that are excluded in configuration in the normal way (dir /*).

["#{base_dir}/**/*"] else # Search the non-excluded top directories, but also add files # on the top level, which would otherwise not be found. wanted_toplevel_dirs.unshift("#{base_dir}/*") end Dir.glob(pattern, flags).select { |path| FileTest.file?(path) } end

Finds all Ruby source files under the current or other supplied directory. A Ruby source file is defined as a file with the `.rb` extension or a file with no extension that has a ruby shebang line as its first line. It is possible to specify includes and excludes using the config file, so you can include other Ruby files like Rakefiles and gemspecs. @param base_dir Root directory under which to search for
ruby source files
@return [Array] Array of filenames
