pview is a perl source code viewer. It highlights the code using a pretty good Perl tokenizer. The color scheme can be very easy customized inside the script. Download pview : https://github.com/trizen/perl-scripts/blob/master/Visualisators/pview On the same concept, a new script has been created, called ' scgrep ' which grabs form a Perl script only the elements that the reader wants. (e.g.: regular expressions, operators, numbers, etc...)
