GNOME Shell browser extension

Introduction

This repository contains the browser extension that provides integration with GNOME Shell and the corresponding extensions repository at https://extensions.gnome.org/.

This extension works in conjunction with its os-native counterpart.

Build

First you need to install the build requirements:

• meson
• python3
• gettext
• p7zip
• polib python module

Then invoke meson to build the extension:

    meson builddir
    cd builddir
    meson compile

This will produce 2 zip files in the builddir folder:

• extension-chrome.zip
• extension-firefox.zip

These files can be uploaded to the corresponding browser add-on websites.
Unpacked extensions are also available in the builddir/extension folder which can be loaded in web browsers for development purposes.

Translations

This project uses the GNOME Translation Project. Translation statistics can be obtained on the corresponding Damned Lies page.

Translation strings handling

All user-visible web extension strings are maintained by developers in the messages.json file, which is located in the extension/extension/_locale/en/ folder. The file format is described here.

The Gettext template is located in po/chrome-gnome-shell.pot and automatically generated using meson:

    meson -Dbuild_messages=true -Dbuild_extension=false builddir
    cd builddir
    meson compile

As result of those commands:

1. The new gettext template will be saved in po/chrome-gnome-shell.pot.
2. All po/*.po files will be updated by msgmerge using the new gettext template.
3. All extension locales (messages.json) will be generated from the gettext po files.

This process is fully compatible with Damned Lies.

There is a limited number of supported locales.
If you use an unsupported locale, Google Chrome will ignore it.

To create a new translation, you can use the msginit command (or any po editor) and the gettext template. Please refer to the Translation Project wiki page for further information about optimal translation workflow.
