GLF OS Welcome Screen

Welcome screen for GLF OS (a Linux distribution based on NixOS) that introduces the main features of the system and launches its in-house tools.

Built with Python, GTK4 and Libadwaita. Available in English and French.

How it works

Pages are declared in src/config.py (PAGES). Each page has:

• a title and a menu label, translated through src/assets/en.po and src/assets/fr.po
• a body written in Markdown in src/assets/localizations/markdowns/<locale>/page_<id>_body.md
• an image and a menu icon from src/assets/images/ (with optional _dark variants)
• an optional command, run by src/infrastructure/api/launcher.py when the page image is clicked:
  • flatpak://<app-id>: flatpak run <app-id>
  • bash://<command>: runs the command in a login shell
  • bashWithPrivilege://<command>: runs the command with pkexec
  • http:// or https://: opens the URL in the default browser

The language is detected from LANG (French for fr_*, English otherwise).

Unchecking "Show this window at startup" writes a hidden desktop entry to ~/.config/autostart/glfos-welcome-screen.desktop. Checking it again removes the file.

Development

On Linux with Nix

nix develop
python src/main.py

To force a language:

python src/main.py --lang=fr_FR

Localization

• UI strings: src/assets/en.po and src/assets/fr.po
• Page bodies: src/assets/localizations/markdowns/en_US/ and src/assets/localizations/markdowns/fr_FR/

If a Markdown file is missing for the current locale, the en_US version is used.

Release for GLF OS

The version is set in src/version.py. After tagging the release on GitHub, update the version and sha256 in assets/glf/pkgs/default.nix:

python update_nix_version.py

To only generate the sha256:

./getGlfSha256.sh X.Y.Z
