edX i18n Tools

Installing

EdX i18n tools are a set of commands useful for developers and translators to extract, compile and validate translations. The edX i18n tools can be installed running the following command inside the extracted directory.

python setup.py install

Running

For Django projects, commands should be run from the root directory, and the default configuration will be found at ./conf/locale/config.yaml. For Django apps, commands should be run from the app's directory, and the default configuration will be found at ./locale/config.yaml.

You can specify a different configuration file with the --config argument.

General Commands

• To extract source strings and populate .po translation files with them
  • i18n_tool extract
• To generate test language(eo) translation files from source .po files
  • i18n_tool dummy
• To compile .po translation files into .mo message files
  • i18n_tool generate
• To find translation errors in .po files
  • i18n_tool validate
• To determine if the source translation files(.po) are up-to-date
  • i18n_tool changed
• To segment a .po file into smaller files based on the locations of the messages
  • i18n_tool segment

Transifex Commands

Developers or translators can use commands provided by edX i18n tools to upload translations to Transifex or download them. Before using these commands one should have an account on transifex.com to create a ~/.transifexrc file. Once the Transifex account has been set up, create a ~/.transifexrc file having these contents:

[https://www.transifex.com]
hostname = https://www.transifex.com
password = YOURPASSWORD
token =
username = YOURUSERNAME(EMAIL)

Also make sure you have a Transifex configuration file .tx/config present under the project directory.

• To upload translations to Transifex
  • i18n_tool transifex push
• To download translations from Transifex
  • i18n_tool transifex pull

Configuration

Details of the config.yaml file are in edx-platform/conf/locale/config.yaml

Changes

v0.5.0

• Added Django22 support.

v0.4.9

• Updated validate to log problems found in translations.

v0.4.8

• Updated transifex to pull files from Transifex that are atleast 3% done previous value was 10%.

v0.4.7

• Test that tag validation catches HTML added to translations.
• When tag validation finds differences, output should be deterministic.

v0.4.6

• Ensure that we only pull files from Transifex that are 10% done. Avoids a problem with our validation code choking on empty po files and avoids translations that are just getting started.
• Don't complain about obviously missing files when cleaning the headers of just-pulled files, and make sure that we do notice the files we did actually pull.
• Ensure that Plural-Forms has a valid value when extracting. python-gettext will choke otherwise.
• When creating a dummy po file, don't garble source strings in a way that relies on the Python dictionary order. This way the result will always be the same no matter the machine.

v0.4.5

• Extract from .jsx files too.

v0.4.4

• Added check-all (check all po files) argument to validate command.

v0.4.3

• Specify Language header for generated dummy po files.

v0.4.2

• Specified utf-8 encoding for .yaml file.

v0.4.1

• Fixes bug preventing the use of --empty with The validate command.

v0.4.0

• The validate command returns a non-zero exit code when problems are detected with the translation files.

v0.3.10

• Add support for edx_lang_map in config.yaml to share translations across language codes.

v0.3.9

• Fix Python 3 issues in validate.

v0.3.8

• Added support for Django 1.11 and Python 3.6

v0.3.7

• A few small fixes for Django projects.

v0.3.6

• Major refactoring to enable use on Django apps as well as Django projects.

v0.3.5

• Pinned a requirement to prevent failures when used with other applications.

v0.3.4

• i18n_tool changed command added. This command determines if the source translation files are up-to-date. If they are not it returns a non-zero exit code.

v0.3.2

• i18n_tool validate no longer complains about problems in both the component .po files and the combined .po files.

v0.3.1

• i18n_tool extract will preserve existing django.po and djangojs.po files in the source directory.

v0.3

• i18n_tool transifex push and i18n_tool transifex pull now can take optional resource names on the command line. If not provided, all resources are pushed/pulled.

v0.2.1

• i18n_tool validate no longer leaves an unneeded messages.mo file behind.

Development

To work on this code:

1. Install Tox:

   $ pip install tox
   

2. Run tests:

   $ tox
   

   If you have failures because msgcat failed, you may need to install it, and adjust your PATH to include it. On a Mac, for example:

   $ brew install gettext
   $ PATH=/usr/local/Cellar/gettext/0.19.3/bin/:$PATH tox
