|
||
| ## Testing the Project | ||
|
|
||
| - Running the tests: | ||
|
|
||
| We recommend using [cargo nextest][cargo-nextest], which is installed by default | ||
| in our [Nix flake](#nix) or can be [installed separately][cargo-nextest-install]. | ||
|
|
||
| ```console | ||
| cargo nextest run --all-features --no-capture | ||
| ``` | ||
|
|
||
| The above command translates to this using the default `cargo test`: | ||
|
|
||
| ```console | ||
| cargo test --all-features -- --nocapture | ||
| ``` | ||
|
|
||
| ## Running the Runtime on Docker | ||
|
|
||
| We recommend setting your [Docker Engine][docker-engine] configuration | ||
| with `experimental` and `buildkit` set to `true`, for example: | ||
|
|
||
| ``` json | ||
| { | ||
| "builder": { | ||
| "gc": { | ||
| "defaultKeepStorage": "20GB", | ||
| "enabled": true | ||
| } | ||
| }, | ||
| "experimental": true, | ||
| "features": { | ||
| "buildkit": true | ||
| } | ||
| } | ||
| ``` | ||
|
|
||
| - Build a multi-plaform Docker image via [buildx][buildx]: | ||
|
|
||
| ```console | ||
| docker buildx build --file docker/Dockerfile --platform=linux/amd64,linux/arm64 -t homestar --progress=plain . | ||
| ``` | ||
|
|
||
| - Run a Docker image (depending on your platform): | ||
|
|
||
| ```console | ||
| docker run --platform=linux/arm64 -t homestar | ||
| ``` | ||
|
|
||
| ## Nix | ||
| This repository contains a [Nix flake][nix-flake] that initiates both the Rust | ||
| toolchain set in [rust-toolchain.toml](./rust-toolchain.toml) and a | ||
| [pre-commit hook](#pre-commit-hook). It also installs | ||
| [external dependencies](#external-dependencies), as well as helpful cargo | ||
| binaries for development. Please install [nix][nix] and [direnv][direnv] to get | ||
| started. | ||
|
|
||
| Run `nix develop` or `direnv allow` to load the `devShell` flake output, | ||
| according to your preference. | ||
|
|
||
| ## Formatting | ||
|
|
||
| For formatting Rust in particular, we automatically format on `nightly`, as it | ||
| uses specific nightly features we recommend by default. | ||
|
|
||
| ## Pre-commit Hook | ||
|
|
||
| This project recommends using [pre-commit][pre-commit] for running pre-commit | ||
| hooks. Please run this before every commit and/or push. | ||
|
|
||
| - If you are doing interim commits locally, and you want to skip the pre-commit checks | ||
| you can run | ||
| `git commit -a -m "Your message here" --no-verify`. | ||
|
|
||
| ## Recommended Development Flow | ||
|
|
||
| - We recommend leveraging [cargo-watch][cargo-watch], | ||
| [cargo-expand][cargo-expand] and [irust][irust] for Rust development. | ||
| - We also recommend using [cargo-udeps][cargo-udeps] for removing unused | ||
| dependencies before commits and pull-requests. | ||
| - If using our [Nix flake](./flake.nix), there are a number of handy | ||
| command shortcuts available for working with `cargo-watch`, `diesel`, and | ||
| other items, including: | ||
| * **`ci`**, which runs a sequence of commands to check formatting, lints, | ||
| release builds, and tests | ||
| * **`db`** and **`db-reset`** for running `diesel` setup and migrations | ||
| * **`doc`** for generating cargo docs with private-items documented | ||
| * **`docker-<amd64,arm64>`** for running docker builds | ||
| * **`nx-test`**, which translates to | ||
| `cargo nextest run --workspace && cargo test --workspace --doc` | ||
| * **`x-test`** for testing continuously as files change, translating to | ||
| `cargo watch -c -s "cargo nextest run --workspace --nocapture && cargo test --doc"` | ||
| * **`x-<build,check,run,clippy>`** for running a variety of `cargo watch` | ||
| execution stages | ||
| * **`nx-test-<all,0>`**, which is just like `nx-test`, but adds `all` or `0` | ||
| for running tests either with the `all-features` flag or | ||
| `no-default-features` flag, respectively | ||
| * **`x-<build,check,run,clippy,test>-<core,wasm,runtime>`** for | ||
| package-specific builds, tests, etc. | ||
|
|
||
| ## Conventional Commits | ||
|
|
||
| This project *lightly* follows the [Conventional Commits convention][commit-spec-site] | ||
| to help explain commit history and tie in with our release process. The full specification | ||
| can be found [here][commit-spec]. We recommend prefixing your commits with | ||
| a type of `fix`, `feat`, `docs`, `ci`, `refactor`, etc..., structured like so: | ||
|
|
||
| ``` | ||
| <type>[optional scope]: <description> | ||
| [optional body] | ||
| [optional footer(s)] | ||
| ``` | ||
