Feature Overview for the PerlPad application

PerlPad Features

You can execute Perl code from almost all Mac OS X applications using the System Services facility.
In any editable text area, just type some Perl code, highlight it and press Cmd-Shift-E to evaluate it. It will be replaced with the result of that expression.
It also works the other way round: select some text and have it processed by any Perl function you can dream up by pressing Cmd-Shift-R (as is process).

You can also turn your favorite Perl one-liners into System Services using PerlPad Add-on Services. This does not require any Cocoa programming. Basically, you just have to type your Perl snippet and optionally choose a keyboard shortcut.

System Services are not the only way to get work done with PerlPad (there is, after all, more than one way to do it). It can also make use of the pasteboard: Copy some text in application A, tell PerlPad to process that text and paste the result into application B. This can be conveniently done with PerlPad's dock menu.
