# Info
### What is Pinnacle?
Pinnacle is a Wayland compositor built in Rust using [Smithay](https://github.com/Smithay/smithay).
It's my attempt at creating something like [AwesomeWM](https://github.com/awesomeWM/awesome)
for Wayland.
### Features
- Tag system
- Customizable layouts, including most of the ones from Awesome
- (Scuffed) XWayland support
- wlr-layer-shell support
- Configurable in Lua or Rust
- wlr-screencopy support
- Is very cool :thumbsup:
### Roadmap
- See [#142](https://github.com/pinnacle-comp/pinnacle/issues/142)
# Dependencies
You will need:
- [Rust](https://www.rust-lang.org/) 1.75 or newer
- Packages for [Smithay](https://github.com/Smithay/smithay):
`libwayland libxkbcommon libudev libinput libgdm libseat`, as well as `xwayland`
- Arch:
```sh
sudo pacman -S wayland wayland-protocols libxkbcommon systemd-libs libinput mesa seatd xorg-xwayland
```
- Debian/Ubuntu:
```sh
sudo apt install libwayland-dev libxkbcommon-dev libudev-dev libinput-dev libgdm-dev libseat-dev xwayland
```
- NixOS: There is flake [`flake.nix`](flake.nix) with a devShell. It also
includes the other tools needed for the build and sets up the
`LD_LIBRARY_PATH` so the dynamically loaded libraries are found.
> Luarocks currently doesn't install the Lua library and its dependencies due to openssh directory
> shenanigans. Fix soon, hopefully. In the meantime you can use the Rust API.
- [protoc](https://grpc.io/docs/protoc-installation/), the Protocol Buffer Compiler, for configuration
- Arch:
```sh
sudo pacman -S protobuf
```
- Debian/Ubuntu:
```sh
sudo apt install protobuf-compiler
```
If you would like to use the Lua API, you will additionally need:
- [Lua](https://www.lua.org/) 5.4 or newer
- [LuaRocks](https://luarocks.org/), the Lua package manager
- Arch:
```sh
sudo pacman -S luarocks
```
- Debian/Ubuntu:
```sh
sudo apt install luarocks
```
- You must run `eval $(luarocks path --lua-version 5.4)` so that your config can find the API
library files. It is recommended to place this command in your shell's startup script.
TODO: other distros
# Building
Build the project with:
```sh
cargo build [--release]
```
> [!NOTE]
> On build, [`build.rs`](build.rs) will:
> - Copy Protobuf definition files to `$XDG_DATA_HOME/pinnacle/protobuf`
> - Copy the [Lua default config](api/lua/examples/default) and
> [Rust default config](api/rust/examples/default_config/for_copying) to
> `$XDG_DATA_HOME/pinnacle/default_config/{lua,rust}`
# Running
> [!TIP]
> Before running, read the information in [Configuration](#configuration).
> [!IMPORTANT]
> If you are going to use a Lua config, you must `cd` into [`api/lua`](api/lua)
> and run `luarocks make [--local]` to install Pinnacle's Lua library.
After building, run the executable located in either:
```sh
./target/debug/pinnacle # without --release
./target/release/pinnacle # with --release
```
Or, run the project directly with
```sh
cargo run [--release]
```
See flags you can pass in by running `cargo run -- --help` (or `-h`).
# Configuration
Pinnacle is configured in your choice of Lua or Rust.
## Out-of-the-box configurations
Pinnacle embeds the default Rust config into the binary. If you would like to use
the Lua or Rust default configs standalone, run one of the following in the crate root:
```sh
# For a Lua configuration
cargo run -- -c "./api/lua/examples/default"
# For a Rust configuration
cargo run -- -c "./api/rust/examples/default_config"
```
## Custom configuration
> [!IMPORTANT]
> Pinnacle is under development, and there *will* be major breaking changes to these APIs
> until I release version 0.1, at which point there will be an API stability spec in place.
### Generating a config
Run the following command to open up the interactive config generator:
```sh
cargo run -- config gen
```
This will prompt you to choose a language (Lua or Rust) and directory to put the config in.
It will then generate a config at that directory. If Lua is chosen and there are conflicting
files in the directory, the generator will prompt to rename them to a backup before continuing.
If Rust is chosen, the directory must be manually emptied to continue.
Run `cargo run -- config gen --help` for information on the command.
## More on configuration
Pinnacle is configured purely through IPC using [gRPC](https://grpc.io/). This is done through
configuration clients that use the [Lua](api/lua) and [Rust](api/rust) interface libraries.
As the compositor has no direct integration with these clients, it must know what it needs to run
through a separate file, aptly called the `metaconfig.toml` file.
To start a config, Pinnacle will search for a `metaconfig.toml` file in the first directory
that exists from the following:
1. The directory passed in through `--config-dir`/`-c`
2. `$PINNACLE_CONFIG_DIR`
3. `$XDG_CONFIG_HOME/pinnacle`
4. `~/.config/pinnacle` if $XDG_CONFIG_HOME is not defined
If there is no `metaconfig.toml` file in that directory, Pinnacle will start the default Lua config
at `$XDG_DATA_HOME/pinnacle/default_config/lua` (typically `~/.local/share/pinnacle/default_config/lua`).
Additionally, if your config crashes, Pinnacle will also start the default Lua config.
> [!NOTE]
> If you have not run `eval $(luarocks path --lua-version 5.4)`, Pinnacle will fallback to the
> embedded Rust config.
### The `metaconfig.toml` file
A `metaconfig.toml` file must contain the following entries:
- `command`: An array denoting the program and arguments Pinnacle will run to start a config.
- `reload_keybind`: A table denoting a keybind that Pinnacle will hardcode to restart your config.
- `kill_keybind`: A table denoting a keybind that Pinnacle will hardcode to quit the compositor.
- The two keybinds above prevent you from getting locked in the compositor if the default config fails to start.
It also has the following optional entries:
- `socket_dir`: A directory that Pinnacle will place its IPC socket in (this defaults to `$XDG_RUNTIME_DIR`,
falling back to `/tmp` if that doesn't exist).
- `[envs]`: A table of environment variables that Pinnacle will start the config with.
For the specifics, see the default [`metaconfig.toml`](api/lua/examples/default/metaconfig.toml) file.
## Lua Language Server completion
A [`.luarc.json`](api/lua/examples/default/.luarc.json) file is included with the default Lua config
and will set the correct workspace library files for use with the
[Lua language server](https://github.com/LuaLS/lua-language-server).
## API references
Lua: https://pinnacle-comp.github.io/lua-reference/main.
Rust: https://pinnacle-comp.github.io/rust-reference/main.
> Documentation for other branches can be reached by replacing `main` with the branch you want.
