This package is used to generate language packs for the JupyterLab ecosystem.

This package performs the following tasks common on JupyterLab core and external extensions:

• Extract strings from code in *.py, *.ts, *.tsx files.
• Extract strings from JSON schema files.
• Create gettext *.pot catalogs.
• Removes duplicate strings from catalogs.
• Create gettext *.po catalogs for specific languages.
• Compile catalogs to *.mo and *.json format to be consumed by the JupyterLab frontend.
• Provide a Hatch Build Hook to compile catalogs when building wheels.
• Update the list of contributors from Crowdin project.

Usage

Bundle catalogs as part of a language pack

This is the recommended way of distributing your localization catalogs.

Visit the language packs repository.

Bundle catalogs with packages

jupyterlab-translate extract <JLAB-EXTENSION-DIR> <JLAB-EXTENSION-NAME>
jupyterlab-translate update <JLAB-EXTENSION-DIR> <JLAB-EXTENSION-NAME> -l es_ES
jupyterlab-translate compile <JLAB-EXTENSION-DIR> <JLAB-EXTENSION-NAME>

Development

Typescript extractor

To extract translatable strings from typescript files, this package relies on gettext-extract. To ease its installation and usage, that tool is packaged within the python package by creating a monolithic JavaScript file using @vercel/ncc compiler.

To update the monolithic file, have a look at the release file.
