Script to list out the functions of a C file

prasanth.pronda has asked for the wisdom of the Perl Monks concerning the following question:

Hi All, I am trying to come up with a script that will list out all the functions & its source code, from a .c file. I tried doing it using Python Lex Yacc. But, it only lists the names of the functions. eg. void foo() { do this & this } I need the script to give me an output similar to the above for all the functions written in a .c file. Does perl provide such facility. Is there any CPAN module already? Any suggestions/advice? Thanks, Prasanth.

See Parse::RecDescent and the demo csourceparser.pl.	[reply]

Inline::C needs to parse C and it contains Inline::C::ParseRecDescent and Inline::C::ParseRegExp. Maybe these two parsers already help you. Alternatively, there are parser generators for Perl as well, see Parse::Yapp and Parse::Eyapp for YACC variants.	[reply]

ctags extracts function names (including position in the source file) from many different programming languages; C is one of them. I'm not sure if it extracts all the information you're interested in, but it's well worth investigating. Perl 6 - links to (nearly) everything that is Perl 6.	[reply]

While Corion and marto already gave you good advice which was Perl-specific as you asked, I'd like to point out that if the Python Lex and Yacc are equivalent to an actual lex and yacc then the shortcoming in parsing C probably isn't your choice of tools. You may want to try gaining a deeper understanding of how to use them, even if that means taking what you learn doing it in Perl back to the Python tools.	[reply]
