Automated i18n tool for Jinja2-based projects using Babel and Google Translate.
- 🔍 Extract translatable strings from your Jinja2 templates.
- 🌐 Initialize
.pofiles for multiple languages. - 🤖 Auto-translate using Google Translate via
deep_translator. - 🛠️ Compile
.pofiles into.mo. - 🧹 Automatically cleans up temporary files like
messages.potandbabel.cfg.
pip install jinja-i18n-toolsActivate your virtual environment, then run:
jinja-i18n fullThis will:
- Copy
babel.cfgto your project root. - Extract translatable strings from your templates.
- Initialize translation files for each language.
- Auto-translate all strings.
- Compile
.pofiles into.mo. - Clean up temporary files.
jinja-i18n extract
jinja-i18n init
jinja-i18n translate --lang ar
jinja-i18n translate-all
jinja-i18n compile
jinja-i18n full --lang all --forceBy default, the following languages are supported:
ar– Arabicde– German
You can customize this in the source by editing the LANGUAGES list.
Your Jinja2 templates and Python files must be located where your babel.cfg expects them. Here's a recommended configuration:
[python: **.py]
[jinja2: templates/**.html]
[jinja2: templates/**.j2]
extensions=jinja2.ext.i18n
This configuration instructs pybabel to:
- Extract translation strings from all Python files recursively.
- Extract translatable content from all
.htmltemplates under thetemplates/folder. - Enable the
jinja2.ext.i18nextension to support{% trans %}blocks.
Make sure this file (babel.cfg) is located in your project root temporarily, or is copied automatically by the tool before running pybabel extract.
Temporary files like babel.cfg and messages.pot are deleted automatically after the process finishes.
