I am new to perl and emacs and want to work with perl in the emacs editor
How can I add perl mode to emacs23 or make it more friendly with perl?
Don't forget that www.emacswiki.org is a gold mine! There is a page at http://www.emacswiki.org/emacs/PerlLanguage
I think the automatic completion for Perl is nice: http://www.emacswiki.org/emacs/PerlCompletion ; There is a vimeo screencast about autocompletion with perl and emacs here: http://vimeo.com/4739908
In addition, I think you should use PDE :
Emacs :: PDE is a collection of Emacs Lisp extensions to facilitate Perl programming. CPerl mode provided an excellent coding environment; Emacs :: PDE provides other common tools, such as creating files using templates, smart compilation, perldoc, perltidy, debugger, tag tree, etc. PDE also provides an easy configuration for Perl programming and a tutorial for beginners using Emacs.
