Overview

OEP-58 proposes changes to the way the Open edX Organization organizes and maintains translation files. Atlas is an Open edX CLI tool that uses git’s sparse-checkout to download directories with the repository openedx-translations. These directories correspond to repositories within the GitHub openedx organization. They contain translation files downloaded from Transifex that have been translated by the Open edX Translations Working Group.

Atlas is intended for both development and deployment, and is meant to be used after cloning a repository with translation files kept in openedx-translations. For instance, when building a docker image or testing localization strings locally. It should not be necessary to run any application in English.

Installation

Atlas itself is a bash script. It is recommended to install it as a package to avoid unintentionally installing breaking changes, while also simplifying the updating process.

Atlas prerequisites are git>=2.20.1 and bash.

Install as a ``pip`` package

Install from PyPI

pip install openedx-atlas  # or add the package to your requirements.txt

Verify that it is installed via atlas --help.

Install as an ``npm`` package

Install from npm.

npm install @edx/openedx-atlas

Then add node_modules/.bin to your PATH.

Verify that it is installed via atlas --help.

Install manually from GitHub releases

This is considered a last resort because of the manual burden of updating the atlas executable version or risking introducing breaking changes to your code.

• Download atlas from the latest release or from the main branch:

curl -L https://github.com/openedx/openedx-atlas/releases/latest/download/atlas -o atlas

• Allow execution with chmod +x atlas

• Either add atlas to your PATH or run it using ./atlas

Usage

The help message below is copied from both atlas --help. It’s updated regularly and useful to understand atlas at a glance.

Atlas is a CLI tool that has essentially one command: `atlas pull`

Configuration file:

    Atlas defaults to using a configuration file named `atlas.yml` placed
    in the root directory. Configuration file:

    pull:
      repository: <organization-name>/<repository-name>
      revision: <git-revision>
      directory: <repo-directory-name>:<local-dir-name> ...
      filter: <pattern> ...
      expand_glob: 0

    Atlas can also use a configuration file in a different path using the `--config` flag
    after `atlas`: `atlas pull --config config.yml`.

    Atlas can also be used without a configuration file by using the flags below after
    `atlas pull`.

Positional arguments DIRECTORY MAPPINGS ...

   One or more directory map pair separated by a colon (:) e.g. FROM_DIR:TO_DIR.

   The first directory (FROM_DIR) represents a directory in the git repository.
   The second directory (TO_DIR) represents a local directory to copy files to.

   At least one directory pair is required:

     $ atlas pull frontend-app-learning/messages:learning-app frontend-lib-test/messages:test-lib

   This syntax is inspired by the `docker --volume from_dir:to_dir` mounting syntax.

Options:

    `-r` or `--repository`:
        slug of the GitHub repository to pull from. Defaults 'openedx/openedx-translations'.

    `-n` or `--revision`:
        Git revision to pull from. Support branches, tags, and commits hashes. Defaults to 'main'.

        This option name used to be `-b` or `--branch`. The deprecated name will be removed in a future release.

    `-f` or `--filter`:
       A comma-separated (or space-separated) list of patterns match files and sub-directories.
       This is mainly useful to filter specific languages to download.

       The same filter is applied to all DIRECTORY MAPPINGS arguments.

       `--filter=fr_CA,ar,es_419` will match both directories named 'es_419' and
       files named 'es_419.json' among others

   `-g` or `--expand-glob`:
       Expand glob pattern e.g. 'atlas pull translations/*/done' to 'atlas pull translations/DoneXBlock/done'
       if it exists.

Example:

    $ cd frontend-app-learning/src/i18n/messages
    $ atlas pull --filter=fr_CA,ar,es_419 \
            translations/frontend-app-learning/src/i18n/messages:frontend-app-learning \
            translations/frontend-component-header/src/i18n/messages:frontend-component-header

    Will result in the following tree:

      ├── frontend-app-learning
      │   ├── ar.json
      │   ├── es_419.json
      │   └── fr_CA.json
      └── frontend-component-header
          ├── ar.json
          ├── es_419.json
          └── fr_CA.json



Commands:
  pull      pull
  -h, --help
      --version

Running Automated Tests Locally

Install

• ShellSpec

• ShellCheck

• getoptions

Run

• make test: run all tests

• make performance_tests: run performance tests which pulls from GitHub.com/openedx

• make unit_tests: run fast unit tests without external dependency

Usage Examples

There’s a couple of patterns that are useful to imitate when using Atlas depending on the use case. atlas pull is most commonly implemented in Makefile, however it can be also used in Dockerfile builds or any other automation tool.

Releasing a New Version

This repository uses semantic versioning with the aid of semantic release to automate the process.

To release a new version, use the conventional commits and the release.yml GitHub action will automatically create a new release and upload the atlas executable.

Note: The atlas --version command only outputs the version if it’s downloaded from a GitHub release. Otherwise, it will output unreleased.
