Hello,

This questions comes from noticing locales aren't detected on Watcher and many other OpenStack projects when `python setup.py install` is executed. The behavior of installing and detecting locales seems to be the same both inside and without a virtualenv.

On  Watcher we do not have a MANIFEST.in file in the repository, what would such a file look like do you perhaps have a reference?

Currently I was thinking of doing something like this:

#setup.cfg[files] data_files =     usr/share/locale/nl/LC_MESSAGES =         watcher/locale/nl/LC_MESSAGES/watcher.mo

This, however, feels clunky and I would expect locale installation and detection to be more automatic.

you can test if locales are detected for a project using:

`oslo_i18n.get_available_languages(DOMAIN)`

In the case of Watcher this only returns `['en_US']` which is inserted as default.

Maybe `python setup.py install` is not the right command to install locales?

Kind regards,

Corne Lukken

Hello,

Good question, I think that both solutions can do the job, and it depends on your needs.

If you choose the second option I think you also need to edit the `MANIFEST.in` to recursively grab your files in your package, then that will look like something like:

# MANIFEST.in
recursive-include translations/ *

# setup.cfg
[files]
packages =
    yourproject
data_files =
   etc/yourproject/translation = translations/*

Where do you want to use this? I mean, do you have a specific project behind this question?

Hello everyone :),

I was wondering what the preferred method to install localization files is. I can think of some probably solutions such as:

1: Including the locale files as part of a package for the target systems package manager (pacman, yum, apt, etc). 2: adding the locale files to the [files] directive in setup.cfg:

I hope someone can answer my question.

Kind regards, Corne Lukken

Hello,

I don't think we need to specify them in setup.cfg. Am I missing something?

I thought so to but I recently checked on Watcher and noticed that executing 'python setup.py install' does not build + move the .mo files into the required locale directories. I proceeded to test on other OpenStack projects and saw the same behavior.

This was verified by listing the available languages with: `oslo_i18n.get_available_languages(DOMAIN)` which than only returns `['en_US']`

Maybe `python setup.py install` is not the correct command to do this?

Kind regards. Corne Lukken

Hi,

I think localization files are automatically included in a python package even if setup.cfg has no explicit entry.

Here is an example of the case of the horizon repository: http://paste.openstack.org/show/786732/ I can see localized files after installing a horizon wheel package into a virtualenv.

These package managers just do the similar thing in a different way.
