It was enabled after the linked bug report, but then disabled again in https://git.archlinux.org/svntogit/packages.git/commit/trunk?h=packages/thunderbird&id=c7100a3bdf66f2c53cc28e29ba7e9ee8865cefac

Commit message doesn't say why. heftig?

Disabled because the localizations do not cover lightning.

Fedora uses a custom script to fetch localizations for Lightning:
http://pkgs.fedoraproject.org/cgit/rpms/thunderbird.git/tree/mklangsource.sh

Maybe we could use it in a bit modified form?

I'm working on a solution to integrate translations, and I'll post it soon.

I attached a diff file for the current thunderbird package, which integrates translations. The same process can be applied for Firefox and SeaMonkey too. Steps:

1. Download translations for all supported languages as tagged snapshots from the mercurial repo. The list of supported languages can be found in mail/locales/shipped-locales.

2. Include translations in the Lightning extension. All of them are merged into one extension.

3. Create langpacks for Thunderbird.

4. Install langpacks.

For the 2. and 3. steps we need to merge translations with en-US to add the missing strings/files, and it requires a command-line tool called 'compare-locales'. I attached a PKGBUILD for this tool.

So we have multiple options:

1. Drop thunderbird-i18n package, and add all langpacks into the main thunderbird package.

2. Drop thunderbird-i18n, and use this package to create split packages for each langpacks as we currently provide them.

3. Don't touch langpacks at all, just include Lightning's translations in its extension, and leave the thunderbird-i18n package as is.

I'm sorry, all downloaded files must be part of the source array. Downloading during the build is to be avoided.

Shouldn't be so hard to move the list of languages to the sources array. Problem is maintaining that array...

I'll post a split package with proper source array soon.

Here is a better diff file for the current thunderbird package. Lightning and langpacks are in split packages.

Since Thunderbird 52 is out now and there is no working Lightning extension ATM, could this be reconsidered?

+1. The separate add-on is no longer compatible, but adding `ac_add_options --enable-calendar` to the PKGBUILD works. I'm not totally sure, but my understanding is that from now on, Lightning will only be available bundled with Thunderbird. Some discussion at this Arch thread [1], and a pertinent reply from the Lightning devs here [2].

@Moabit : can you post as attached file the full modified PKGBUILD which allowed the lightning plugin to be built ?

thunderbird package has just been updated ( 52.0-2 ), it solves the problem

@potomac Yes, so my PKGBUILD [1] was fairly similar to 52.0-2. I can also confirm that this version fixes the problem.
