I haven't had a chance to try the script out, but I'd like to get myself set up to use some of these tools that provide refactoring capacity. I have briefly looked at Komodo and Eclipse but my development environment doesn't make them particularly easy to use and I haven't been able to take the time to get myself setup with them. I've been using emacs for years and just haven't seen the value in switching just yet.

I would definitely be interested to see other's comments on refactoring tools for Perl. I know Devel::Refactor was built specifically for use within Eclipse. Any others out there?

perl -e 'split//,q{john hurl, pest caretaker}and(map{print @_[$_]}(joi
+n(q{},map{sprintf(qq{%010u},$_)}(2**2*307*4993,5*101*641*5261,7*59*79
+*36997,13*17*71*45131,3**2*67*89*167*181))=~/\d{2}/g));'

After reading this thread, I hooked up a small Devel::Refactor script to emacs at the weekend. It works, but I haven't used it seriously, and I'm not convinced it provides a huge productivity leap

Anyway, here's how...

in your .emacs:


(defun refactor-extract ()
  "Change region into a subroutine"
  (interactive)

  (shell-command-on-region (point) (mark) "./refactor-extract" t)
  )

and some Perl in refactor-extract:


#!/usr/bin/perl

### Rewrite code block as a subroutine
#   This is mostly intended to be used through emacs'
#   shell-command-on-region
#
#(defun refactor-extract ()
#  "Change region in to a subroutine"
#  (interactive)
#  (shell-command-on-region (point) (mark) "./refactor-extract" t))
#

use strict;
use warnings FATAL => 'all';
use Devel::Refactor;

my $code = join '', <>;
my $name = "refactored_" . sprintf( "%04d", rand() * 10000 );
print join "\n", Devel::Refactor->new->extract_subroutine( $name, $cod
+e );

This was a quick hack, quickly hacked. Use at your peril.
