[antlr-interest] antlr-interest Digest, Vol 65, Issue 1

[Jim Idle]

Please read the API docs about the various @sections. However, make sure that you keep as much code as possible out of the actions in the grammar. All you should have is API calls to some kind of interface object, which you can certainly add in to the headers:

@includes
@header
@preincludes
@postinclude

See: Using Sections within Grammar Files: http://antlr.org/api/C/index.html

Use StringStream instead of FileStream. Download the examples zip file and look at the examples in the C directory.
