Localization¶

Translation Process¶

If you’re interested in contributing translations to Mattermost, please join the Mattermost localization channel to discuss. Below are descriptions of the overall localization process.

Initial Translation¶

To translate a language:

1 - Join the Mattermost Translation Server.

2 - Confirm that the language you want to help translate is listed in the Translation Server.

• If it is, perhaps offer to help translate or review and make suggestions.
• If not, ask to setup your language on the Mattermost localization channel, so you can start helping with the translation.

3 - Review translation rules written by localization leads, when applicable:

• French (Règles pour la traduction francophone de Mattermost)
• German (Regeln zur Übersetzung von Mattermost)

Translations Updates¶

1 - New and updated strings are imported to the Mattermost Translation Server each day at 00:00 GMT. Strings with a mobile prefix are imported from the mattermost-mobile project, others are from mattermost-server and mattermost-webapp.

2 - A new pull request with latest translations that reach at least Beta Quality is submitted to the mattermost-mobile, mattermost-server and mattermost-webapp repos each Monday at 22:00 GMT.

• A pull request will also be submitted on the day of major feature complete and code complete to ensure latest translations are included in the release.
• A pull request may also be submitted for a release candidate.

IMPORTANT: Please do not submit translations directly with a pull request as they may be lost with the next updates from the Mattermost Translation Server.

Translation Quality¶

So users understand the accuracy and coverage of language translations, quality levels are explicitly defined for each language:

Test Translations¶

If you’d like to review and verify translations prior to achieving Beta-quality status, you can follow these steps:

1 - Build Mattermost on your machine following the Developer Machine Setup Guides.

2 - Download a copy of your translations to your local machine.

3 - Use Mattermosti18n to convert Pootle’s output into JSON files.

4 - Copy the generated [locale].json files to the corresponding directories:

• For the server, copy the files to the i18n directory of the mattermost-server project.
• For the webapp, copy the files to the i18n directory of the mattermost-webapp project.

5 - Modify the file i18n/i18n.jsx in the mattermost-webapp project to include your translated strings.

6 - Compile and run Mattermost to confirm everything works. You can then review and verify translations from your machine.

Translation Maintenance¶

Translations require updates on a monthly basis as features are added and changed. The formal process for updates has yet to be determined.

Below are current official reviewers and maintainers for languages that have reached at least Beta-quality. Official reviewers submit final translations for languages; maintainers suggest translations and step in when official reviewers aren’t able to help in a certain release.

If you’re interested in contributing to the process, please join the Mattermost localization channel to discuss. Creating localization channels is also encouraged - see examples of current channels including Italian, German and Swedish.
