Hi, I fixed a small bug which locks up the search when entering empty search strings; plus removed some useless subs. Please download again.

    thanks again. The following patch adds capability of searching with regexes (I get some utf8 errors, but it works. Do you happen to know how to fix them?):
    18c18 < my ($recurse, $name, $case,$linenums,$quick_start) =(0,0,0,0,0); --- > my ($recurse, $name, $case,$linenums,$quick_start, $use_regex) =(0,0 +,0,0,0); 21a22 > if( grep{/\bR\b/} @ARGV ){@ARGV = grep { $_ ne 'R' } @ARGV; $use_reg +ex = 1 }; 64a66 > my $vboxC3 = Gtk2::VBox->new(); 83a86,91 > my $checkbutton5 = Gtk2::CheckButton->new('Use RegEx'); > $checkbutton5->signal_connect( clicked => > sub{check_button_callback($checkbutton5, \$use_regex , +'use_regex')}); > $vboxC2->pack_start( $checkbutton5, 0, 0, 0 ); > > if($case){$checkbutton5->set_active(1);} 87c95 < $vboxC2->pack_start( $checkbutton4, 0, 0, 0 ); --- > $vboxC3->pack_start( $checkbutton4, 0, 0, 0 ); 91a100 > $hboxt->pack_start( $vboxC3, 0, 0, 0 ); 284,285c293,307 < if ($case){$regex = qr/\Q$search_str\E/} < else{$regex = qr/\Q$search_str\E/i} --- > if ($case){ > if ($use_regex) { > $regex = qr/$search_str/; > } > else { > $regex = qr/\Q$search_str\E/} > } > else { > if ($use_regex) { > $regex = qr/$search_str/i; > } > else { > $regex = qr/\Q$search_str\E/i; > } > }

      I "think" I found the answer to the "malformed utf8 errors". It probably only works for those using latin1 encoding. Possibly, it can be adjusted to use whatever encoding you use? Anyways, change the line which opens the file from
      open (FH,"<", $_); # to open (FH,"<:encoding(latin1)", $_);
      Anyways, it works for me in stopping the errors. I can't say how the regex search works in all it's complexity, for instance a really complex regex may need some special handling, but so far, so good. :-)

      Here is a complete patched snippet. I added another feature to skip search directories that begin with the number 1. (The code is commented out, but you may activate it). I store alot of html files for my categories, in 1DOCS, and I prefer not to delve into them on recursive searches. Modify to fit your needs.

        Thanks a bunch, ++zentara!

        Last thing I was thinking about (except excluding dirs (for me it would be .svn dirs or so)) would be a start dir parameter. But I can easily do that myself.

      Hi, I believe I found a bug in your patch , which may be causing your problem. Your line
      > if($case){$checkbutton5->set_active(1);}
      probably should be
      > if($use_regex){$checkbutton5->set_active(1);}
      That would screw up the if-else clause, by cross-linking $case and $use_regex; but I'm still testing it. :-)

      My first guess would be to put "use utf8" at the top of the script. But you might want to post a new toplevel question for this? I will test it today and see what I can figure out.
