Dakota GNOME Extensions

Dakota packages curated GNOME Shell extensions built from source or upstream repositories directly into the immutable system image.

When to Use

• Packaging a new GNOME Shell extension into elements/bluefin/shell-extensions/
• Updating or patching an existing extension in elements/bluefin/shell-extensions/
• Enabling or configuring default extension settings in dconf schemas
• Resolving extension compatibility for the tracked GNOME version (GNOME 45–50+)

When NOT to Use

• Packaging native system software, CLI tools, or background daemons → load dakota-packaging
• Low-level OCI layer composition → load dakota-image
• Developer/CI workflows → load dakota-ci

Core Process

1. Verify Upstream Extension:
   • Inspect metadata.json for supported shell-version entries (must match Dakota's GNOME release, currently targeting GNOME 50).
   • Ensure code uses modern ESM syntax (import ... from 'resource:///...').
2. Create Element:
   • Add elements/bluefin/shell-extensions/<name>.bst using kind: manual.
   • Source from pinned git commit or release tag.
   • For release ZIPs with metadata.json at the archive root, set base-dir: "" in the kind: zip source. The plugin default ('*') extracts a child directory instead, dropping root-level files. Inspect the pinned archive's layout before choosing an extraction root; source-tree archives may have a wrapper directory.
   • Extract UUID via jq and install files into:

     _uuid="$(jq -r .uuid metadata.json)"
     _dest="%{install-root}%{datadir}/gnome-shell/extensions/${_uuid}"
     install -d "${_dest}"
     cp -R * "${_dest}/"
     

3. Compile Schemas:
   • If the extension ships a schemas/ directory, compile schemas in install-commands:

     glib-compile-schemas "${_dest}/schemas"
     

4. Aggregate in Stack:
   • Add the new extension element to elements/bluefin/gnome-shell-extensions.bst.
5. Configure Default Enablement:
   • Check both files/dconf/ and elements/bluefin/shell-extensions/disable-ext-validator.bst, which generates Dakota's default enabled-extensions schema override.
   • Enable basic desktop behavior by default only when its pinned metadata supports the target Shell version and its backend services are available. Personal integrations (sync/VPN controls, clipboard history, extra audio controls, and power reminders) remain opt-in with their dependencies installed. BudsLink may stay enabled because its default panel is hidden without supported devices. A disabled version validator does not establish compatibility.
   • For administrator-managed prerequisites, provide explicit setup from the control rather than silently granting permissions. Dakota's Tailscale setup uses a narrowly scoped, administrator-authenticated helper; it does not authorize users at boot.
   • Diagnose live settings with /usr/bin/gsettings and gnome-extensions, not Homebrew's GSettings CLI. Existing user lists can mask new defaults; preserve those selections rather than installing login migrations to force new defaults.
6. Validate & Build: Graph validation (bst show) does not stage sources or execute installation commands. Build the changed extension and inspect its installed metadata and schemas; a green graph check alone cannot verify archive extraction.
