[ Göran Uddeborg] Pattern for spell-checking in po-files.

I'd like to ask for ispell support for .po files.  .po files are
translation files as used by the gettext tools collection.  Basically
they contain the english message (msgid) and translation (msgstr)
provided by the translator, plus comments (# ):

# this is the first message
#, c-format
msgid ""
"this is a message."
msgstr ""
"dies ist eine Meldung."

# this is the 2nd message
#, c-format
msgid ""
"this is the sencond message."
msgstr ""
"dies ist die zweite Meldung."

ispell should check text after "# " (but not after "#[.,:]") and inside
the field 'msgstr' only.  Göran Uddeborg already came up with the
appended extension to po-mode.el.  I'd recommend to add something along
these lines to ispell.el (as already done for 'tex).

For testing more .po files you can find here:

I made a little hook to po-mode to set up patterns for ispell so only
the translated strings and translator comments are checked.  This
might be a too trivial thing, but I haven't seen it elsewhere so I
thought I'd post it.  So I get some help with debugging! :-)

Maybe I will trigger someone to post their own much better ideas?

This is not perfect in any way.  Since the po file is in read only
mode, you can only use it to detect misspellings, but not fix them
on-the-fly in the ordinary ispell-mode way.

(defun po-mode-ispell-pattern ()
  "Add ispell patterns so that only translated messages are checked."
  (make-variable-buffer-local 'ispell-skip-region-alist)
  (add-to-list 'ispell-skip-region-alist '("^msgid" . "^msgstr"))
  (add-to-list 'ispell-skip-region-alist '("^#[:,]" . "\n")))
(add-hook 'po-mode-hook 'po-mode-ispell-pattern)

[...]

Certainly.  Some questions:

Do we _always_ want to only check the msgstr values, or does it make
sense to check the English text as well?

I would prefer to have this automatic based on major or minor mode.  I
didn't locate any po-mode library...  can you send that to me to help
testing?

In my short evaluation, the following regexp seems to be an
improvement:

("^msgid" . "^msgstr")

replaced by:

("^\\(#~ \\)?msgid" . "^\\(#~ \\)?msgstr")

Calling make-variable-buffer-local from a function doesn't make sense
(I wish it were easier for the byte-compiler to check and warn about it).
You want to use make-local-variable instead.

Thanks!  (It's a big language, Elisp, with lots left for me to learn!)

I agree this is a good idea.
