The settings application for the COSMIC desktop environment. Developed with libcosmic, using the iced GUI library.

To compile, a stable Rust compiler and just are required.

• cargo
• just
• mold

Some C libraries are also required for font support at the moment.

• cmake
• libexpat1-dev
• libfontconfig-dev
• libfreetype-dev
• pkg-config

Then it can be compiled and installed like so.

just
sudo just install

If packaging for a Linux distribution, vendor dependencies locally with the vendor rule, and build with the vendored sources using the build-vendored rule.

just vendor
just build-vendored

When installing files, use the rootdir and prefix variables to change installation paths.

just rootdir=debian/cosmic-settings prefix=/usr install

Translation files may be found in the i18n directory. New translations may copy the English (en) localization of the project and rename en to the desired ISO 639-1 language code. Translations may be submitted through GitHub as an issue or pull request. Submissions by email or other means are also acceptable; with the preferred name and email to associate with the changes.

Run the cosmic-settings binary with just run so that logs will be emitted to stderr, and crashes will generate detailed backtraces. Applications shouldn't crash, so when writing code, avoid use of unwrap() and expect(). Instead, log errors with tracing::error!() or tracing::warn!().

This project is split across the following workspace members:

• app: cosmic-settings GUI frontend and binary
• page: library for creating and handling settings pages
• pages: libraries for page-specific logic

When creating a new page, UI-specific code will go directly into app, and page-specific logic will go into a crate under the pages directory. This is mainly to isolate page-specific crate dependencies and logic from the UI; so that the source code specific to the UI is easier to maintain and refactor.

Eventually, pages may be separated into plugins, and this will help with that migration.
