komorebi for KDE is built up as a Cargo workspace with one crate per concern,
the way komorebi and komorebi for Mac are. The first two crates are the
`komorebi` daemon, which does nothing yet but report its version, and `version`,
which owns the string every binary of the workspace reports.
`version` reads the commit from git when HEAD is on a branch, and from
COMMIT_HASH otherwise. A jj workspace leaves HEAD detached, so
`.cargo/config.toml` defaults the variable to `unknown` (nix will set the real
commit), and a plain `cargo build` in a jj checkout compiles.
The tooling files come from komorebi for Mac: the licence, deny.toml (trimmed to
the licences in use), rustfmt.toml and the toolchain file. `just check` runs the
formatting check, clippy and rustdoc with warnings denied, and the tests.
rustfmt.toml uses an unstable option, so formatting needs a nightly rustfmt. The
`rg` calls in `just lint` name a path because rg reads stdin when it is given
none and stdin is not a terminal.
The README and CONTRIBUTING.md say how to run, check and commit.
