perl-mode.el file in Mac OS X

perl-mode.el file in Mac OS X

[Nicholas Tamara]

Hello,

Can anyone point me to the right location to place the perl-mod.el
file so that the emacs that comes with Mac OS X recognizes .pl files
as Perl script files? Thanks.

Not exactly perl-mod.el related, but these snippets in your .emacs
should work with any similar package:

(add-to-list 'load-path (expand-file-name "~/.elisp"))

Put perl-mod.el inside ~/.elisp, then add also:

(if (load "perl-mod" 't)
    (setq
     auto-mode-alist
     (cons '("\\.pl$" . post-mode) auto-mode-alist)))

If later you byte-compile perl-mod, then instead this will use the
faster-loading resulting .elc file.

EmacsWiki is your friend!

Cordially, Ismael

It's not the Elisp file that you have to put anywhere -- it's probably 
right now in a place that Emacs searches. You can check that with "C-h 
v load-path" and then check that you to have

/usr/share/emacs/21.2/lisp/progmodes/cperl-mode.el
/usr/share/emacs/21.2/lisp/progmodes/perl-mode.el


What you need to do is to either "(require 'perl-mode)" actively or to 
set auto-mode-alist in a manner like this (to have only one place where 
you augment this list):

(setq auto-mode-alist
   (append
     '(("\\.xsl$"       . sgml-mode)
       ("\\.plist$"     . sgml-mode)
       ("\\.idd$"       . sgml-mode)
       ("\\.ide$"       . sgml-mode)
       ("\\.xml$"       . xml-mode)
       ("\\.xsl$"       . xml-mode)
       ("\\.fo$"        . xml-mode)
       ("\\.nw$"        . noweb-mode)
       ("\\.f90$"       . f90-mode)
       ("\\.pl$"        . perl-mode)
       ("\\.pod$"       . perl-mode)
       ("\\.tgz$"       . tar-mode)
       ("\\.tar\\.bz2$" . tar-mode)
       ("\\.tar\\.gz$"  . tar-mode))
   auto-mode-alist))

IIRC, the problem with the .pl extension is that it's used both for Perl and
Prolog files, so I recommend people avoid it and use one of the many other
possible extensions, such as ".perl".

Oh and BTW, while I'm posting a useless message, I might as well use
<anal-mode> and point out that the above regexps should be "\\.xsl\\'",
"\\.plist\\'", ..., "\\.pl\\'", ..., "\\.tar\\.gz\\'" (i.e. replace $ with
\\' because $ would also match an embedded newline in a file name whereas
\\' really only matches the end of the file name).

If you feel like shortening such a list, you can also use things like:

(setq auto-mode-alist
   (append
     '(("\\.\\(xsl\\|plist\\|id[de]\\)\\'"     . sgml-mode)
       ("\\.\\(xml\\|xsl\\|fo\\)\\'"           . xml-mode)
       ("\\.nw\\'"                             . noweb-mode)
       ("\\.f90\\'"                            . f90-mode)
       ("\\.\\(pl\\|pod\\)\\'"                 . perl-mode)
       ("\\.\\(tgz\\|tar.\\(gz\\|bz2\\)\\)\\'" . tar-mode))
     auto-mode-alist))

This one can be made even shorter. Left as an exercise to the
reader. =:)

I don't think a file named woozle.tarigz should trigger tar-mode.  And
regexp-opt suggests

"\\.t\\(?:ar\\.\\(?:bz2\\|gz\\)\\|gz\\)\\'"

A file with such a stupid name would hang Emacs anyway. :o)

Ah, that's good news! I've seen a few times this "...\\'" and wondered 
what it might mean.

Thank you for making my evening brighter!

Instead, you could have looked up the "regular expressions" node in
the manual.
