Weblate: Update base language file using POST_UPDATE_SCRIPT

In our AngularJS project, translation strings are marked using angular-translate's <translate> tag and extracted using gulp-angular-translate-extract. This is run automatically by Weblate using a POST_UPDATE_SCRIPT, so the developers shouldn't have extract strings manually.

This is the post update script:

#!/bin/bash
gulp --gulpfile gulp-i18n-extract.js

And for reference, this is the gulpfile:

#!/usr/bin/env gulp --gulpfile

'use strict';

var gulp = require('gulp'),
    angularTranslate = require('gulp-angular-translate-extract');

gulp.task('default', function() {
    return gulp.src('src/**/*.{html,js}')
        .pipe(angularTranslate({
            lang: ['en'],
            defaultLang: 'en',
            suffix: '.lang.json',
            safeMode: false,
            dest: './src/languages',
            stringifyOptions: true, // Sort alphabetically.
            verbose: false
        }))
        .pipe(gulp.dest('./src'));
});

The script is run and will extract the strings. So changes to the base language file are displayed in the Repository details view as pasted below:

On branch master
Your branch is up-to-date with 'origin/master'.
Changes not staged for commit:
  (use "git add <file>..." to update what will be committed)
  (use "git checkout -- <file>..." to discard changes in working directory)

    modified:   src/languages/en.lang.json

no changes added to commit (use "git add" and/or "git commit -a")

My problem is that the changes are not noticed by Weblate, so in order to get updated strings into Weblate, I've had to manually run:

django-admin loadpo --force --all

Also, when I do commit changes, the base language file will not be committed.

What am I doing wrong here?

Solution

Weblate needs to see the file in the Git repository, it doesn't look for uncommited changes.

So to fix this, commit the file to git in the hook as well:

git commit -m 'Update source strings' src/languages/en.lang.json

PS: I've updated the documentation to cover this as well.
