Re: Checking the include form and getting only the header name

#!/usr/bin/perl -w
use strict;

while (my $line = <DATA>) {
    chomp $line;
    if ($line =~ /#include [<"](\w+\.h)[>"]/) {
        print "file is: $1\n";
    }
}

__DATA__
#include "string.h"
#include <string.h>

Note that your usage of \w matches only one character — you'd need \w+ to match more than one. Also, you have the .h outside of the <...> or "...".

Sometimes there are comments at the end,so that scenario also needs to be takin into account `/files/src/services/usb_dcd/private/internals.h:#include "queue.h" /c +omments/` [download]	[reply] [d/l]
