At the risk of being slightly off-topic, I would also share my 2c Emacs tip with you. I've put this hook to call perltidy (pressing F6) in my .emacs:
in reply to Desparately seeking a bilingual vim/Emacs expert
The hook has to be added to the correct customisation variable as well:
(defun my-cperl-hook ()
"What to run when cperl-mode is turned on"
;; Function to call perltidy
(defun perltidy-whole-buffer ()
"Filter the current buffer through perltidy"
(point-min) (point-max) "perltidy -st"
nil 1 shell-command-default-error-buffer
;; Bind key
(define-key cperl-mode-map [f6] 'perltidy-whole-buffer)
Of course, s/cperl/perl/g if you don't want to use cperl.
;; custom-set-variables was added by Custom -- don't edit or cut/pas
;; Your init file should contain only one such instance.
'(cperl-mode-hook (quote (my-cperl-hook)))
Flavio (perl -e "print(scalar(reverse('ti.xittelop@oivalf')))")
Don't fool yourself.
