I just went through a similar exercise myself. I did not find C::Scan to be useful, and Parse::RecDescent can do it, but probably too much work for your needs.

You really want to use Regexp::Common here.

Something like this should get you started:
use Regexp::Common; my $func_rx = qr{ ([a-zA-Z]\w*) # match function name \s* # optional space ($RE{balanced}{-parens='()'}) # match parameter list }sx; while( $code =~ /$func_rx/g ) { print "func = $1\n"; print "param list = $2\n"; }

This will match things like if( !foo ) though, so you will probably have to explicitly skip built-in keywords like that.

Note that this is certainly not a complete solution for you, but just to point out Regexp::Common is a handy tool that should help.

Also you probably want to strip out all the comments first, so they dont throw off your matching regex. But this can also be done with Regexp::Common:
$code =~ s/$RE{comment}{'C++'}//g;

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
