Perl Programming Tools - (who, what, where, when, and why)
In the Win32 environment, xemacs used to be a favourite, but Optiperl (particularly the latest version 4 -- in beta) is now indispensible. I had tried Komodo earlier, but found it too clunky -- maybe it's improved. Eventually paid for Opti (it's pretty cheap) and now have ballooned perldoc, configurable syntax colouring that includes block and parenthesis marking, cgi testing with in built web server,or with local apache, remote ops, a code library to take snippets for easy insertion, a regex tester, perl tidying, debugging, file unzipping, project and CVS interfaces, and a handy code explorer detailing imports, variable usages etc..
