crowdin_sync.py
==================

Introduction
------------
This script is used to synchronize CyanogenMod's translations with Crowdin's. Also, it can handle
automatic commiting to Gerrit and pushing/downloading to/from Crowdin.

Prerequisites
-------------
The Ruby variant of crowdin-cli >= 0.5.2 is required for this to work.

    \curl -sSL https://get.rvm.io | bash -s stable --ruby
    source /home/your_username/.rvm/scripts/rvm # Add this to your .bashrc file!
    rvm all do gem install crowdin-cli

python-git is used for Git integration.

    sudo apt-get install python-git

Copy <cm_version>_extra_packages.xml to .repo/local_manifests of each <cm_version> tree
to make sure you sync all the extra packages not included in the main manifest.

Executing
---------
Export the following environment variables to set the API keys and the base path.
Base path should contain all CM trees in subfolders, named after CM branches.
Syncing stable trees requires an additional environment variable plus a 'stable'
subfolder under the base path, due to crowdin API limitations:

    export CM_CROWDIN_API_KEY=your_api_key
    export CM_AOSP_CROWDIN_API_KEY=your_aosp_api_key
    export CM_CROWDIN_BASE_PATH=your_base_path
    export CM_CROWDIN_STABLE_BASE_PATH=your_stable_base_path

Example:

    export CM_CROWDIN_API_KEY=1234567890
    export CM_AOSP_CROWDIN_API_KEY=0987654321
    export CM_CROWDIN_BASE_PATH=/mnt/android/cm
    export CM_CROWDIN_STABLE_BASE_PATH=/mnt/android/cm/stable

Execute:

    ./crowdin_sync.py --username your_gerrit_username --branch cm_version --ticket jira_id [--upload-sources] [--upload-translations] [--download]

Bugs
----
 - When committing fails, the reason of it cannot be determined. Often this is just when there
   are no new translations, so the script will not exit when this happens.
