New template for 'guix-manual' made available

[Translation Project Robot]

Hello, gentle maintainer.

This is a message from the Translation Project robot.  (If you have
any questions, send them to <coordinator@translationproject.org>.)

A new POT file for textual domain 'guix-manual' has been made available
to the language teams for translation.  It is archived as:

    https://translationproject.org/POT-files/guix-manual-1.0.0-pre1.pot

Whenever you have a new distribution with a new version number ready,
containing a newer POT file, please send the URL of that distribution
tarball to the address below.  The tarball may be just a pretest or a
snapshot, it does not even have to compile.  It is just used by the
translators when they need some extra translation context.

Below is the URL which has been provided to the translators of your
package.  Please inform the translation coordinator, at the address
at the bottom, if this information is not current:

    https://lepiller.eu/files/guix-1.0.0-pre1.tar.gz

We can arrange things so that translated PO files are automatically e-mailed
to you when they arrive.  Ask at the address below if you want this.

Thank you for all your work,

                                The Translation Project robot, in the
                                name of your translation coordinator.
                                <coordinator@translationproject.org>

Now’s the right time to translate Guix and the manual so that 1.0 is
available in your native language!

I can translate the Guix manual into Chinese if no one else is willing
to do so.  But I don't have much time and will probably miss the
deadline for Guix 1.0.

I have no previous experience with i18n.  What should I know in order to
translate the Guix manual?  How do I edit the ".pot" file?  Is there an
emacs package for the job?

emacs’ po-mode is part of gettext.

You will also need to join the Translation Project:

https://translationproject.org/team/index.html



You need to put your translations in a .po file, not in the .pot file.
This is what I did back then (once there is a po file it is no longer
this complicated).  I am not sure if there are easier ways to test an
initial po file.

Then I did this but it was not the right command:

You should not need to do this msginit.  You should instead use the po
file at the Translation Project if they have one for your language
team.  If not, then you should not use po/doc/guix-manual.pot as I did
but use the .pot file at
https://translationproject.org/domain/guix-manual.html or else the
Translation Project will not accept the po.

Then:

You should check if you get a working manual before submitting the po
file to the Translation Project robot’s e-mail.

Hi!

I'm glal you're willing to translate to your native language! So get started, you need to register with the translation project for your language. You do not need to sign the waiver form for guix, so it should be rather quick.

To start working on translations, you'll have to download the pot file from the TP. Do not use the one in our repository. Then I know there is an emacs mode for gettext, but I don't know how to use it. You can also use poedit which is easy to use and can import pot files. In any case you'll have to produce a po file, which is very similar to the pot file, except for some headers. I also started developping offlate (https://framagit.org/tyreunom/offlate) that can automate fetching from the TP and sending to them, but it's not as good as I'd want.

Once you have translated, you'll have to send your work to the TP robot. You can do that even if your work is only partial.

I think the priority is to translate the guix domain first, before the manual. Make sure noone is listed as responsible for the translation on the TP and you should be good.

Thank you!

[PATCH 0/2] Removal of generated files (was Re: Let’s translate!)

[Miguel]

Hello everybody!

I'm currently working on the Spanish translation for the manual,
although I will send the guix domain translation as soon as TP
coordinators change the assignation.

Regarding the translation process, I think we should remove, at least,
the generated files from the repository. AFAIK the only show-stopper is
automake. It reads the translated files before make invocation, so the
manual .texi files are needed for the bootstrap, even though they are
listed in BUILT_SOURCES. guix/self.scm scan their content too in order
to generate version-LL.texi. Stubs could be generated before calling
autoreconf inside bootstrap script.

After that change, adding the spanish (or any new) translation should be
only matter of applying a patch like the second one, but with more
translated content...

WDYT? Any ideas about automated synchronization with
translationproject.org as make update-po does?

Best regards,
Miguel

This is a very good idea, but I think it leaves a stub texi that won't get rebuilt because it's younger than po files. What if we add a toucgh invocation to reset the modification time of these stubs, to ensure make will want to rebuild them?

Yes, you are right indeed. I didn't noticed because I was updating
the .po file manually.

What about the attached patch? I've just tested it with the other
patch that seems to be missing or blocked by its size, nothing up my
sleeves this time. 0:-)

Thank you! I've just pushed it and removed doc/guix.*.texi and
doc/contributing.*.texi from the repository, added them to .gitignore
too.

Thank you very much, my emacs and magit will thank you too, as each

There was an issue introduced by that patch: the manual was not
generated by guix pull anymore. The attached patch fixes that. WDYT?

We should probably make a separate derivation (and a separate procedure)
to build the translated Texi files.  Maybe we can think about it later,
though.

What about moving all this to (guix build po) or similar?  It would
export \x18read-po-file\x19, which takes an input port and returns an alist of
message ID/translations.  I don\x19t want to think about parse trees as a
user of the API.  :-)

This function is too long, could you split it?
Maybe it should be called \x18translate-texi\x19?

I guess this could become the body of a \x18translate-cross-reference\x19
procedure or similar?

Use \x18match\x19.

Could you send an updated patch?

I would put po.scm in MODULES_NOT_COMPILED.

I’d remove all the ‘tmp-’ in here since they don’t add anything, and I’d
suggest adding a comment below the ‘define’, like:

  ;; Translate Texinfo file SOURCE using messages from PO, and write the
  ;; result to OUTPUT.

The thing in the middle should be wrapped like this:

  (regexp-quote (string-join (string-split …)))

Typo.

Should be ‘translate-cross-references’ (plural), no?

Please align ‘if’ like so:

  (if condition
      then
      else)

You probably need something like this to add (guix build po) to the
result of ‘guix pull’:

Otherwise LGTM!  Please make sure that ‘make as-derivation’ works as
intended (builds the translations, installs (guix build po)) if you
haven’t done it already.

Thanks!

Hello,

Julien Lepiller <julien@lepiller.eu> skribis:

> This is a very good idea, but I think it leaves a stub texi that won't get rebuilt because it's younger than po files. What if we add a toucgh invocation to reset the modification time of these stubs, to ensure make will want to rebuild them?

Also, I don’t actually use the ./bootstrap script.  :-)

Shouldn’t we instead replace the existing %.texi targets in doc/local.mk
with a phony target like ‘update-texi’, and then add:

  dist-hook: update-texi

?

This would be similar to the ‘update-po’ rule generated by Gettext in
po/.

Thanks,

Currently it is only a call to autoreconf -fvi, but it's there for a
reason, isn't it?

> Shouldn’t we instead replace the existing %.texi targets in
> doc/local.mk with a phony target like ‘update-texi’, and then add:

The procedure needed currently to a new translation for the manual is:
  1. modify doc/local.mk, po/doc/local.mk and so on. 
  2. guix.LL.texi must be manually generated somehow even though it is
  listed in BUILT_SOURCES.
  3. automake can run without errors with the rules in order to generate
  the actual translated file.
  4. The resulting files are committed.

The problem is that automake parses .texi files for the @setfilename
tag. On the other hand, guix.LL.texi and contributing.LL.texi are
generated files, and they shouldn't be on the VCS, just like neither
configure nor Makefile.in are, though they are distributed. My patch
tries to avoid this issue creating stub files that will be overwritten
with the actual content. This has the advantage of keeping clean git
status from other modifications than .po files changes.

This may sound familiar to this community, it actually is a bootstrap
problem. Running autoreconf -fvi actually tells you that that file is
missing, so that part is easy to fix. On the other hand, as far as I
tested if it does not contain a line with version-LL.texi,
version-LL.texi won't be generated.

I actually agree with Miguel here. The phony target would not allow us
to update the manual. It's probably a matter of preferences, but I
prefer an up to date manual with some English sentences than a fully
translated but outdated manual. I wouldn't use a manual that could
refer to an older version.

Also Miguel's solution looks a lot more clean in the bootstrapping
point of view, and I think this is a strong argument in this
community :)

You will only be bothered when new translations appear, in which case
you'll have to run ./bootstrap again, but on the other hand, you will
never be bothered by *.texi files being changed all the time.

It’s there mostly because people are used to having such a file, but I
like the fact that it does nothing magical.

I agree that up-to-date is preferable.

So what would one have to do when preparing a new release?  Presumably
nothing because the up-to-date texi files would be checked in?

IOW, running ./bootstrap is something what would matter primarily to
translators, is that correct?

Thanks,

It would be needed to build the translated manuals, so I think it would be needed to successfuly run make from the git checkout. Translators should not even care about the source. Or maybe running only autoreconf will simply not build the translated manuals, I'm not sure.

But once you run ./bootstrap once, you should not have to run it again until a new language is available for the manual.

I see, sounds good to me.

I think you can go ahead and push!

Applied, thanks a lot!

If you ‘guix pull’ now, you should be able to run “info guix.es”.  \o/

According to the stats at
<https://translationproject.org/domain/guix-manual.html>, Spanish debuts
at #2.  :-)

(Thanks also for the translation note about gender neutrality in
Spanish, which is indeed as tricky as in French.)

I've found this emacs config (~/.emacs) in linux.org.ru, that makes workable emacs commands (such as C-c C-c) when keyboard layout is not English. It works for me in Russian layout, and Chinese too as I tried.

;;Make emacs commands work when keyboard layout is not English
(defun reverse-input-method (input-method)
  "Build the reverse mapping of single letters from INPUT-METHOD."
  (interactive
   (list (read-input-method-name "Use input method (default current): ")))
  (if (and input-method (symbolp input-method))
      (setq input-method (symbol-name input-method)))
  (let ((current current-input-method)
        (modifiers '(nil (control) (meta) (control meta))))
    (when input-method
      (activate-input-method input-method))
    (when (and current-input-method quail-keyboard-layout)
      (dolist (map (cdr (quail-map)))
        (let* ((to (car map))
               (from (quail-get-translation
                      (cadr map) (char-to-string to) 1)))
          (when (and (characterp from) (characterp to))
            (dolist (mod modifiers)
              (define-key local-function-key-map
                (vector (append mod (list from)))
                (vector (append mod (list to)))))))))
    (when input-method
      (activate-input-method current))))

(defadvice read-passwd (around my-read-passwd act)
  (let ((local-function-key-map nil))
    ad-do-it))

(reverse-input-method 'russian-computer)


There are suggestions for emacs config to make po-mode by default and also ispell spellchecker in my blog:

Hope it helps!

Thank you for the trick.  The default behavior of Emacs is indeed
annoying if a special input method is enabled.  But I only enable
Chinese Input Method when I input Chinese characters.  That's less than
1% of my time with Emacs.  So I am OK with the default behavior.

Julien and Florian can provide guidance, as you’ve seen.  :-)

As for the deadline: even a partially translated manual can help.  When
you have something that you deem useful (for example, you translated the
intro and the installation sections), then you can probably submit them
to the Translation Project so that we can integrate it.

Thank you!

Re: Let’s translate!

I had this idea to translate guix manual into Russian from October '18. That was not easy to get around with this. But now I have emacs with po-mode. And I will do it in a free time. Think, till January '20 Russian guix manual will be ready.
