# Contributing to Zellij
|
||
|
||
Thanks for considering contributing to Zellij!
|
||
|
||
**First**: if you're unsure of anything, feel free to ask on our [Discord
|
||
server](https://discord.gg/MHV3n76PDq). We're a friendly and welcoming bunch!
|
||
|
||
# Code of Conduct
|
||
|
||
Before contributing please read our [Code of Conduct](CODE_OF_CONDUCT.md) which
|
||
all contributors are expected to adhere to.
|
||
|
||
## Building
|
||
To build Zellij, we're using cargo-make – you can install it by running `cargo
|
||
install --force cargo-make`.
|
||
|
||
To edit our manpage, the mandown crate (`cargo install
|
||
mandown`) is used and the work is done on a markdown file in docs/MANPAGE.md.
|
||
|
||
Here are some of the commands currently supported by the build system:
|
||
|
||
```sh
|
||
# Format code, build, then run tests and clippy
|
||
cargo make
|
||
# You can also perform these actions individually
|
||
cargo make format
|
||
cargo make build
|
||
cargo make test
|
||
# Run Zellij (optionally with additional arguments)
|
||
cargo make run
|
||
cargo make run -l strider
|
||
# Run Clippy (potentially with additional options)
|
||
cargo make clippy
|
||
cargo make clippy -W clippy::pedantic
|
||
# Install Zellij to some directory
|
||
cargo make install /path/of/zellij/binary
|
||
# Publish the zellij and zellij-tile crates
|
||
cargo make publish
|
||
# Update manpage
|
||
cargo make manpage
|
||
```
|
||
|
||
To run `install` or `publish`, you'll need the package `binaryen` in the
|
||
version `wasm-opt --version` > 97, for it's command `wasm-opt`.
|
||
|
||
To run `test`, you will need the package `pkg-config` and a version of `openssl`.
|
||
|
||
<details>
|
||
<summary>Should you be a `nix` (linux/macOs) user, you can use the following
|
||
commands in order to get set up: (expand)</summary>
|
||
|
||
- `nix develop`
|
||
Download and set up dependencies.
|
||
- `nix build`
|
||
Build the binary in the `result` directory. (--release)
|
||
- `nix run`
|
||
Run the binary.
|
||
- `cachix use zellij`
|
||
Will use our binary cache as a substituter.
|
||
</details>
|
||
|
||
## Running the end-to-end tests
|
||
Zellij includes some end-to-end tests which test the whole application as a black-box from the outside.
|
||
These tests work by running a docker container which contains the Zellij binary, connecting to it via ssh, sending some commands and comparing the output received against predefined snapshots.
|
||
|
||
<details>
|
||
<summary>Should you be a macOS (including m1) user, please follow these commands before. (expand here):</summary>
|
||
|
||
1. `rustup target add x86_64-unknown-linux-musl`
|
||
2. `brew install messense/macos-cross-toolchains/x86_64-unknown-linux-musl`
|
||
3. `export CC_x86_64_unknown_linux_musl=$(brew --prefix)/bin/x86_64-unknown-linux-musl-gcc`
|
||
4. `export AR_x86_64_unknown_linux_musl=$(brew --prefix)/bin/x86_64-unknown-linux-musl-ar`
|
||
5. `export CARGO_TARGET_X86_64_UNKNOWN_LINUX_MUSL_LINKER=$CC_x86_64_unknown_linux_musl`
|
||
</details>
|
||
|
||
|
||
To run these tests locally, you'll need to have either `docker` or `podman` and also `docker-compose` installed.
|
||
Once you do, in the repository root:
|
||
|
||
1. `docker-compose up -d` will start up the docker container
|
||
2. `cargo make build-e2e` will build the generic linux executable of Zellij in the target folder, which is shared with the container
|
||
3. `cargo make e2e-test` will run the tests
|
||
|
||
To re-run the tests after you've changed something in the code base, be sure to repeat steps 2 and 3.

||
## How we treat clippy lints
|
||
|
||
We currently use clippy in [GitHub Actions](https://github.com/zellij-org/zellij/blob/main/.github/workflows/rust.yml) with the default settings that report only [`clippy::correctness`](https://github.com/rust-lang/rust-clippy#readme) as errors and other lints as warnings because Zellij is still unstable. This means that all warnings can be ignored depending on the situation at that time, even though they are also helpful to keep the code quality.
|
||
Since we just cannot afford to manage them, we are always welcome to fix them!
|
||
|
||
Here is [the detailed discussion](https://github.com/zellij-org/zellij/pull/1090) if you want to see it.

### Lacking API for plugin in Zellij?
|
||
|
||
If you have a plugin idea, but Zellij still doesn't have API required to make
|
||
the plugin consider opening [an issue][plugin-issue] and describing your
|
||
requirements.
