Thanks to all who responded to my recent LEX question.. I managed to take
two of the 4 responses I got and merge them for a solution.. Another question
comes up, now:
I'm still having fun with preprocessors. What I now need to do is to
implement a (YACC) grammar to preprocess hunks of code, disregarding
code that is the actual program body wherever necesary..
For example, Here is a possibility:
? (VAR debug_mode:boolean := TRUE,
unhappy_mode:boolean := TRUE; );?
<lots of program body here #1>
PROCEDURE [XREF] Moo (x:integer);
<lots of program body here #2>
PROCEDURE [XREF] Moo2 (x:real);
For clarification of my ambiguous comment above, what I need to do is to
take a YACC grammar that will accept preprocessor directives but that has
no clue about the programming language itself. Thus, I will need to
disregard code that is in "<lots of program body here #1>". I can deal
with program bodies #2 and #3 and their appropriate manipulation, but
can't comprehend how to disregard all that middle code. Anyone have an
idea? Thanks in advance!
