[P5P] Update cperl.el for Perl 5.10?

There's still people inciting editor^Hoperating system wars for the lulz?:)

I'm wondering if it's best overall to keep a copy of cperl-mode in the
perl distribution at all. It has been in at least two major GNU Emacs
releases and likely to be out of date when someone finds it in the per
distribution.

I'm fine with removing emacs/* if people say it's obsolete. I've no
idea of what those three files are for, though.

emacs/cperl-mode.el is a (better) Perl editing mode for Emacs.
It is actively maintained by Ilya Z. Including the most recent version
in the 5.10 kit would be a good idea. Also, maybe add a README in the
emacs directory with something like "These files are maintained by
Ilya Z. Please visit .... for updates.".

emacs/e2ctags.pl converts emacs-style tags file to ctags format.

emacs/ptags add XS capability to the emacs-style tags file generator.


Maybe we should add a more general document on Perl support in
editors? Vim, Emacs, JEdit, Eclipse, ...

Dual-life it?

SCNR,

It's now time for 5.12 and cperl-mode.el is out of date again. 5.10
was released with ilya's version 5.23 but his latest is now 6.2.

Meanwhile Emacs 23.1 itself and Emacs's Git HEAD are different than
both of those. Both the 23.1 version and the Git HEAD version have
according to inspecting a diffs between them and Ilya's and looking at
git-log, received bugfixes and improvements that aren't in Ilya's
modes.

According to logs our cperl-mode was first included with Perl 5.2 in
1995 and had a lot of activity throughout 1996 and 1997. Then in
November 1997 it was included into Emacs itself and was part of the
20.1 release in September 1997.

Is there really any reason to include cperl-mode.el in perl core
anymore? It has been in 6 major Emacs releases for well over a decade.
The Emacs version is more current, works, and is what the vast
majority of Emacs users use. If someone really wants to use Ilya's
version they shouldn't get it from perl core since that version may
be out of date (although probably not, the last version was in 2008).

If we should be shipping a custom cperl-mode.el we should be shipping
jrockway's version (http://github.com/jrockway/cperl-mode) and not
Ilya's. It supports changes in Perl as of 5.10 and there's a branch
for it to support highlighting of Moose-based code.

I think it is too late to do anything for 5.12.0 now, as it should ship
without *any* more changes at all except removing the "RC1" tag from
patchlevel.h.

If we don't drop it from 5.12.0, then we are probably stuck with it for
5.12.1 as well.

I do support dropping cperl-mode.el from the Perl releases in 5.13.

Cheers,
-Jan

The versions as distributed with Emacs are so buggy as to be unusable.

Really? What's wrong with them in particular? I read over the diff
between the two (http://paste.scsys.co.uk/41545) and couldn't spot
anything obvious. I've also used Emacs's version for years without
encountering any problems that I could see your version fixing.

I gave up on analysis many years ago. All I know that ALL bug reports
I get against these versions are resolved by just switching to my stuff.
Some time ago they claimed a resync. I have no idea on the details...

Some version, not quite sure whose (I think Ilya's) occasionally begin
refusing to type more characters because some exception is being
thrown. I've never gotten far enough into the code to be able to
submit a bug report on it. Whenever this happens (it's kind of rare)
I've just disabled cperl-mode and used fundamental-mode to be able to
continue typing.

No version that I'm aware of handles highlighting right enough for the
code I've got it on. Pod parsing foils it, unescaped ' and " inside
quoted regions (like regexps) foil it, etc. I looked into the source
once to see about fixing this but never figured out what was going on.

I continue to wish to be able to disable the auto-indenting feature
and have tab/untab just indent/outdent to relative tab stops (but with
spaces).

Is there a proper bug tracker for cperl-mode.el? I swear, I'll report
proper bugs next time!

Trivial. (And has nothing to do with cperl.)

Yours,
Ilya
