Adding cli for langpacks

[Kristina Hoeppner]

When Mahara is being updated to a new minor or major version, admins need to remember to pull language packs separately as they are not part of the core distribution. This cli script will make that easier.

This this cli does:
1) Install / update langpacks by listing the languages by their code, eg de = German, fr = French like so

sudo -u www-data php admin/cli/sync_langpacks.php -l=de,fr

This will make a backup of the existing language (if exists) into the dataroot langpacks_backup directory.

2) If you don't want to make backups then add the -b=false flag, eg

sudo -u www-data php admin/cli/sync_langpacks.php -l=de,fr -b=false

3) If you need to rollback the backups you can use the -r=true flag, eg

sudo -u www-data php admin/cli/sync_langpacks.php -l=de,fr -r=true

Could we imagine that, as it is the case with Moodle, this script becomes part of the upgrade.php script and automatically upgrade the langpack to the latest version of the release at each upgrade?

The upgrade script would look at the installed langpacks and upgrade them with the latest version.

Langpacks (I am talking about the French's one at least) are evolving with the feedback of users pointing out mistranslation or grammar/spelling mistakes. So it is good to update the pack on one's distro time to time. The upgrade.php could do this.

Hi Dajan,

Currently we only generate lagpack tarballs for the _STABLE of a branch, see http://langpacks.mahara.org/

This means if one is upgrading from say 15.10.1 to 15.10.2 but the latest branch version is 15.10.6 they would get the 15.10.6 specific langpack and there could be changes in the language strings that cause problems, eg in 15.10.2 we might have a string 'copymodule' but in 15.10.6 it might be 'copymodule1' so the expected translation string will be missing.

Eventually we would want something like what Moodle has - but before we can do that we need to generate langpacks for each version of each branch.

So the current plan is an interim measure - allowing for admins / deployment scripts the ability to run this manually and to roll back if the update of the languages causes problems.

Cheers

Robert

Bug 1625863: Adding cli for langpacks

This cli does:

1) Install / update langpacks by listing the languages by their code,
eg de = German, fr = French like so

sudo -u www-data php admin/cli/sync_langpacks.php -l=de,fr

This will make a backup of the existing language (if exists) into the
dataroot langpacks_backup directory.

2) If you don't want to make backups then add the -b=false flag, eg

sudo -u www-data php admin/cli/sync_langpacks.php -l=de,fr -b=false

3) If you need to rollback the backups you can use the -r=true flag, eg

sudo -u www-data php admin/cli/sync_langpacks.php -l=de,fr -r=true

It will ignore trying to update the 'en' language as that is set
within the Mahara system itself
