ANTLR-Mode for Emacs
The package ANTLR-Mode makes Emacs the perfect IDE for the development of ANTLR grammar files. ANTLR is a LL(k)-based recognition tool which generates lexers, parsers and tree transformers in Java, C++ or Sather and can be found at <http://www.antlr.org/>.
This package provides the following features:
- Consistent Indentation. You do not have to insert or delete the correct amount of spaces or tabs manually to indent a line according to ANTLR's coding style: just press TAB. It is even done automatically if you insert an ANTLR syntax symbol (one of :;|&(){}). Use the menu to indent all lines in a selected region.
- Syntax Highlighting. When enabled, this mode highlights grammar symbols (syntax symbols and keywords: bold black, rule references: dark blue, token references: dark orange, rule/token definition: bold blue) and the code in actions. See example.
- Code Browsing. Find the definition of a rule, token, or grammar class by using the Index menu, a keyboard command or selecting an entry in the speedbar frame.
- Fast Navigation. Move to the next or previous rule definition or to the beginning or end of the rule body by one or two key strokes.
- Action Visibility. Control the visibility of less important code like actions.
-
Option Support. Insert or change one of
ANTLR's options by a using the menu or a keyboard command. This
mode knows the options supported by ANTLR, their allowed values and the correct
position where to insert the option (and the surrounding
options{}if necessary). - Tool Invocation. Run ANTLR from within Emacs and find the error position by selecting the error message via the mouse or a keyboard command.
-
Makefile Creation. Show the makefile
dependencies for all grammar and generated files in the current directory. For
it, this mode considers the value of ANTLR's
languageoption, import/export vocabularies and grammar inheritance. See example.
