Perl "plugin" for Emacs

Perl "plugin" for Emacs

[paxxus]

Hi,

I'd like to be able to perform some text formatting in Perl as that will be
way faster for me than having to learn Lisp. Here's what I'm after:

1. Select a region in Emacs.
2. Press a key.
3. The selected text is passed to a Perl script.
4. Output from Perl script replaces the selected region.

Is this possible and what exactly would I have to put in my .emacs if, let's
say, the key I want to bind is F5 and the Perl script is located at
~/Emacs/format.pl

Thanks!

Look up the function shell-command-on-region.

Thanks! I put the following code in my .emacs (using cksum as the command for testing):

(global-set-key (kbd "<f5>") '(shell-command-on-region "cksum"))

But I get the following error when I press F5:

Wrong type argument: commandp, (shell-command-on-region "cksum")

I figured out how to do it. I put this command into my .emacs:

(global-set-key
  (kbd "<f5>")
  ( lambda () (interactive)
    ( shell-command-on-region
      (region-beginning) (region-end) "perl ~/Emacs/format.pl" nil t
    )
  )
)

Thanks for the help!
