Mark invalid entries in po files as fuzzy | ||
######################################### | ||
|
||
Context | ||
******* | ||
As of the `OEP-58`_, the Transifex GitHub App is used to sync Translations. | ||
These translations are validated by `LexiQA`_, built-in Transifex quality | ||
checks, and human reviewers. During this synchronization process, the | ||
`Transifex GitHub App`_ creates pull requests to this repository. The | ||
translations in the pull requests are then validated by ``msgfmt`` in CI. | ||
|
||
Problem | ||
******* | ||
There are times when the translations being synchronized fail ``msgfmt`` | ||
validation. This prevents the pull requests from being merged. | ||
|
||
|
||
Design Decision | ||
*************** | ||
|
||
A GitHub Actions workflow will be implemented to mark invalid entries in | ||
synchronized ``.po`` files as ``fuzzy``. This will update pull requests | ||
created by the `Transifex GitHub App`_. | ||
|
||
To ensure a safe and reliable workflow, the following workflows will be | ||
combined into one single workflow with multiple jobs: | ||
|
||
#. Run ``python-tests.yml`` to validate the python code | ||
#. Then, run ``validate-translation-files.yml`` which performs the following: | ||
|
||
#. Validate the po-files using ``msgfmt`` | ||
#. Notify the translators about the invalid entries via the preferred | ||
communication channel (Slack, Transifex, GitHub) | ||
#. Edit the po files to mark invalid entries as ``fuzzy``, so it's | ||
excluded from ``.mo`` files | ||
#. Revalidate the files | ||
|
||
#. Commit the updated entries and push to the PR branch | ||
#. Automatically merge the PR | ||
|
||
|
||
Informing the Translators | ||
************************* | ||
Translators can be notified about invalid translations via Slack, Transifex | ||
or GitHub issues depending on the community's preference. | ||
|
||
Pros and Cons | ||
************* | ||
|
||
**Pros** | ||
|
||
* New valid strings would make it into the ``.mo`` files | ||
* There's no need for manual intervention, therefore it's fast and won't | ||
create a backlog of pull requests. | ||
* Rejected strings are easily identifiable by looking in the code, so it's | ||
easy to fix them. | ||
* Translators can be notified about invalid translations via Slack, Transifex, | ||
GitHub depending on the community's preference. | ||
|
||
|
||
**Cons** | ||
|
||
* The workflow script runs and edits the pull request, which can be | ||
confusing for the reviewers. | ||
* Previously valid entries are going to be overwritten with new ``fuzzy`` | ||
strings which will make those entries to be shown in source language | ||
(English). | ||
|
||
Rejected Alternative: Keep pull requests open | ||
********************************************* | ||
|
||
- **Create a Transifex issue only:** It would be possible to identify the | ||
faulty entries and create a Transifex issue via API to the faulty entries. | ||
However, this would require attention from the translators | ||
team, which can take a rather long time therefore creating a backlog of | ||
invalid entries. Additionally, Transifex issues are not understood or used | ||
by most of the Open edX community. | ||
|
||
- **Post errors on Slack only:** Post the errors on Slack and ask the | ||
translators | ||
to fix them. Same as the previous option, not all translators are on Slack. | ||
Additionally, this option would have a slow feedback loop causing the pull | ||
requests backlog to build-up. | ||
|
||
- **Mark faulty entries as unreviewed only:** Use the Transifex API to mark | ||
the the invalid entries as unreviewed, then pull only | ||
reviewed entries into this repository. | ||
This option would require an extensive use the of the Transifex API, | ||
and pull again which can be complex to implement. Additionally, this option | ||
would have a slow feedback loop causing the pull requests backlog to | ||
build-up. | ||
