[antlr-interest] #defines in C target

[Justin Murray]

Hello,

 

I am building a parser for a C target, and am running into issues with
the generated #defines from the lexer tokens. Essentially, the lexer
names that were chosen in some cases conflict with other #defines in the
code (either from our own code, or from standard libraries like
Windows.h). While I realize that I could just rename the lexer rules to
remove the conflict, this makes the grammar file less readable, and at
this point is a considerable amount of work (our language has hundreds
of keywords). Is it possible to tell the lexer generator to
prefix/postfix all of these defines to make them more unique, while
preserving the nice, readable grammar definition file?

 

Thank you,
