Extracting fn prototypes

bubulik has asked for the wisdom of the Perl Monks concerning the following question:

I was planning to write a Perl script that wud extract some fn prototypes frm my org's src code base (significantly huge). The code is mostly in C and some in C++. While some fns have prototypes, others r simply declared and defined in same spot. Some code even use old school C style fn declarations (ie not writing fn params within round brackets). I have a sneaky feeling that there r utils or tools out there that accomplish this task (besides the Perl script would be hairy/scary given the inconsistencies in coding standards here). Any idea/suggestions? Thnx.

Essentially, you're looking something akin to HTML::Parser, but for the C++ language. A quick scan of c parser provides the following possibilities: C::Include C::Scan C::Sharp Deval::Tokenizer::C I have never used these modules, but that should provided you with a starting point.

Hi, I would refer you to the ctags as it is made for what you are trying to do. Jason L. Froebe No one has seen what you have seen, and until that happens, we're all going to think that you're nuts. - Jack O'Neil, Stargate SG-1	[reply]

Uh, it isn't really. Tags are there to help you locate the function implementation, not the prototype declaration. They don't contain functions that are declared only in headers and have no imlementation (in available source). Tag files don't contain accurate function signature information, so if you're going to use them you still have to do some scanning of the source code data yourself to fix it up.	[reply]

"fn" is an old (mathematical?) abbrieviation for "function". That's probably the only acceptable abbrieviation in the bunch.	[reply]
