# GNOME Shell extensions

All extensions are packaged automatically. They can be found in the `pkgs.gnomeXYExtensions` where XY is a GNOME version. The package names are the extensions' UUIDs, which can be a bit unwieldy to use. `pkgs.gnomeExtensions` is a set of manually curated extensions that match the current `pkgs.gnome-shell` versions. Their names are human-friendly, compared to the other extension sets. Some of its extensions are manually packaged.

## Automatically packaged extensions

The actual packages are created by `buildGnomeExtension.nix`, provided the correct arguments are fed into it. The important extension data is stored in `extensions.json`, one line/item per extension. That file is generated by running `update-extensions.py`. Furthermore, the automatically generated names are dumped in `collisions.json` for manual inspection. `extensionRenames.nix` contains new names for all extensions that collide.

#### To package the extensions for a new GNOME version:

1. Add a new `gnomeXYExtensions` set in `default.nix`.
2. Update `all-packages.nix` accordingly. (grep for `gnomeExtensions`)
3. Update `supported_versions` in `update-extensions.py`.
4. Follow the [For everyday updates](#for-everyday-updates) section.

#### For GNOME updates:

1. Follow the [To package the extensions for new GNOME version](#to-package-the-extensions-for-new-gnome-version) section, if required.
2. Update `versions_to_merge` variable in `./update-extensions.py`.
3. Run `update-extensions.py --skip-fetch`, and update `extensionRenames.nix` according to the comment at the top.
4. Update `gnomeExtensions` in `default.nix` to the new versions.

## Manually packaged extensions

Manually packaged extensions overwrite some of the automatically packaged ones in `pkgs.gnomeExtensions`. They are listed in `manuallyPackaged.nix`; every extension has its own sub-folder.
