# LIBCOSMIC

A platform toolkit based on iced which provides the building blocks for developing the
future COSMIC desktop environment. Applications and applets alike are equally supported
targets of Libcosmic. Applets integrate directly with COSMIC's interface as shell
components, which was made possible by the Layer Shell protocol of Wayland.

## Building

Libcosmic is written entirely in Rust, with minimal dependence on system libraries. On
Pop!_OS, the following dependencies are all that's necessary compile the cosmic library:

```sh
sudo apt install cargo cmake just libexpat1-dev libfontconfig-dev libfreetype-dev pkg-config
```

Some examples are included in the [examples](./examples) directory to to kickstart your
COSMIC adventure. To run them, you need to clone the repository with the following commands:

```sh
git clone https://github.com/pop-os/libcosmic
cd libcosmic
git submodule update --init --recursive
```

If you have already cloned the repository, run these to sync with the latest updates:

```sh
git fetch origin
git checkout master
git reset --hard origin/master
git submodule update --init --recursive
```

The examples may then be run by their cargo project names, such as `just run cosmic-design-demo`.

To create a new COSMIC project, use `cargo new {{name_of_project}}` to create a new
project workspace, edit the `Cargo.toml` contained within, and add this to begin.

```toml
[workspace.dependencies.libcosmic]
git = "https://github.com/pop-os/libcosmic"
default-features = false
features = ["wayland", "tokio"]
```

Alternatively, to create a new package after running `cargo new {{name_of_project}}`,
edit the `Cargo.toml` within, and edit the dependencies section to look like this.

```toml
[dependencies]
libcosmic = { git = "https://github.com/pop-os/libcosmic", default-features = false,
                features = ["wayland", "tokio"] }
```
