NAME

warnings::regex::recompile - Get Warnings about regex/pattern recompilation in Perl code.

VERSION

Version 0.01

SYNOPSIS

warnings::regex::recompile gives Warnings with the line numbers if any regex/patten is getting recompiled in Perl code .

It is Prgamatic module, so one can use it like this;

use warnings::regex::recompile;

Example, #strings.pl

my @regexps = qw( foo bar baz ); my @strings = qw( abc def ghi );

for my $string (@strings) {

   for my $regex (@regexps) {

      $string =~ /$regex/
   
   }

}

In this case, warning will be like this,

[ WARNING : Pattern bar is getting re-compiled on 7 in strings.pl. You are advised to use qr// operator, which boost the speed/performance of your code. ]

[ WARNING : Pattern baz is getting re-compiled on 7 in strings.pl. You are advised to use qr// operator, which boost the speed/performance of your code. ]

[ WARNING : Pattern foo is getting re-compiled on 7 in strings.pl. You are advised to use qr// operator, which boost the speed/performance of your code. ]

This module also figure out the variable name if the variable has dynamic regex. for exa:

#Time.pl my $a = "abcdefghijklmnopqrstuvwxyz"; my $b = 1;

for (1..1000) {

        $b = ($b + 1) % 10; 
        
        #print "b : $b\n";
                
        $a =~ s/$b a//; 
}

In this case, warning will be like this,

[ WARNING : Variable $b is getting re-compiled on 19 in Time.pl. You are advised to use qr// operator, which boost the speed/performance of your code. ]

#Module gives [NO WARNINGS !!!] if there is no regex/pattern getting recompiled.
