First off, an upstream LibreOffice installation is always self-contained in a single location and fully relocatable.  The soffice executable finds all the installation's files relative to itself.  Some Linux distros might lay this out differently, with their downstream LibreOffice installations distributed in some way into the distro's file system hierarchy, but that is strictly a downstream issue beyond the scope of upstream LibreOffice here.

If I understand you correctly, what you seek is that a LibreOffice installation at e.g. ~/.guix-profile/lib/libreoffice/ would not only look for certain locale-specific files under ~/.guix-profile/lib/libreoffice/{program/resource/,share/}, but also under say ~/.guix-profile/lib/libreoffice-langpack-fr/{program/resource/,share/}.  (And if that understanding is not correct, please be more specific in the description of your actual issue.)

Something like that is not currently supported.  There would apparently be some design space how LibreOffice could be taught to look into further places (environment variables, well-known paths, whatever...).  A related issue is issue 129177.

This is useful information, thank you!

I'm only getting started looking at packaging the language packs of
LibreOffice for GNU Guix, so I'm not sure what are the requirements
yet -- I was only looking at how things are done in Debian and
commenting about their layout.

Given that soffice is capable to find things relatively to its own
location, unless it de-references symbolic links (heavily used by Guix
profiles), it should be able to find language pack data if I put such
data at the expected location.

Which brings me to the question: what is the expected location for
language pack data; what is the recommended layout?  Is there a place I
can read more about it (actual documentation or sources) ?

And do these language packs contain both the translation of the
LibreOffice applications themselves (e.g. the menus and button texts) as
well as the offline help?

Thank you for your time,

Maxim

The easiest way to get an idea here is probably to look at how the deliverables for a version of upstream LibreOffice like <https://downloadarchive.documentfoundation.org/libreoffice/old/7.6.2.1/> are split up for the various platforms.  For deb and rpm, you see that both helppacks and langpacks are individually split out for all the languages, and you can look into their content to see what exactly gets split out and where it ends up in the (monolithic) installation.  (mac and win are each a bit different: I think for mac we bundle the help content in the langpacks, and I think for win we bundle all the language's non-help content directly in the main msi.)

As I understand this ticket, it is a enhancement request to add an environment variable[1] that would point to the language pack location, is that right?

Cloph, any thoughts on the topic?
