bug#24442: gettext: No PO mode for Emacs (or wrong description)

[Ivan Vilata i Balaguer]

The description for ``gettext@0.19.8`` (current) includes this sentence:

    It provides translators with the means to create message catalogs,
    as well as an Emacs mode to work with them, and a runtime library to
    load translated messages from the catalogs.

However, no output of the package includes the files for Emacs.

One solution (please note that I'm very new to Guix) may be to provide
an output for the Emacs goodies, another one would be removing the
reference to the Emacs mode in the description until it's actually
there.`;)`

Thanks!

Thanks for the report!  This happens because there is no emacs
dependency (input) in 'gettext' package definition, so Emacs is not
found during 'configure' phase (as can be seen in the log¹: «checking
for emacs... no»), so elisp files are not compiled and installed.

I would say this can simply be fixed by adding:

  (native-inputs `(("emacs" ,emacs-minimal)))

to the gettext package definition (also (gnu packages emacs) module
should be used), and I checked it by making a variant of the gettext
package with this line; however when I tried it on a real gettext
package, I saw that a whole world will be rebuilt (apparently it is a
'core-updates' thing).  And I realized that emacs (even its minimal
variant) will probably be a too heavy dependency for such a core thing.

So perhaps it is time to make 'gettext-minimal' and to use it as the
dependency for other packages and 'gettext' (with Emacs tools) intended
to be installed by users (as it is done for bash/bash-minimal).  WDYT?
(this is a question for Guix developers)

I think a special output is not needed, as the resulting *.el[c] files
weigh much less than 1MB.

I think it’s a good idea; in commencement.scm, we’ll need to inherit
from gettext-minimal to avoid the Emacs dependency.

Most of the packages that currently depend on gettext will have to be
changed to gettext-minimal, as you wrote.

When that it’s done, we can happily add all sorts of dependencies to
gettext, including additional languages for which it provides bindings.

Sounds like a plan no?

Another option would be to hack a phase that copies the .el files to the
output, without compiling them, but I don’t think it’s as nice as the
above plan.

Thanks,
Ludo’.

Yes, I'm sending 2 patches to guix-devel for adding 'gettext-minimal'
and for adding missing *.el files to 'gettext'.

I agree, it doesn't look so nice.

This is fixed in 'core-updates' branch now:
<http://git.savannah.gnu.org/cgit/guix.git/commit/?id=9e01589469abd89e035450d29026f0e14add6801>,
however since the fix is not available for users (until core-updates
will be merged into master) I think it's better to leave this bug
opened.

Once the fix appears in 'master' (I will let you know when it happens),
a user could do "guix pull" and install (or update) 'gettext' in his/her
profile.  Then 'po-mode' will become available by default (without any
additional settings in user's .emacs), it means that whenever you will
open .po file, 'po-mode' will be loaded and enabled automatically.

Working like a charm since the last upgrade, thank you!
