Hi guys,
As a part of my project i need to parse a "c source code" into tokens.I
need
to process the tokens to identify some predefined patterns.I searched in
google
and got some suggestions about pycparser and ply.
ply looks like a general purpose lex/yacc replacement...
pycparser uses ply internally and generates the AST.
I am doubtful if you need pycparser. Take the source and
use only the lexer... You do not need a parser to tokenize.
This is a lex version of the C language

Do the values 'returned' contain enough info for you? If so,
lex is the tool.
