Depending on your tastes, you can bootstrap your development environment in a traditional Rust way or through Nix.
|
|
|
|
## The Nix way
|
|
|
|
Nix is a generic package manager we use to precisely define our development environment.
|
|
Instructions on how to install it are given on their [Download page](https://nixos.org/download.html).
|
|
|
|
Check that your installation is working by running the following commands:
|
|
|
|
```
|
|
nix-shell --version
|
|
nix-build --version
|
|
nix-env --version
|
|
```
|
|
|
|
Now, you can clone our git repository (run `nix-env -iA git` if you do not have git yet):
|
|
|
|
```bash
|
|
git clone https://git.deuxfleurs.fr/Deuxfleurs/garage
|
|
cd garage
|
|
```
|
|
|
|
*Optionnaly, you can use our nix.conf file to speed up compilations:*
|
|
|
|
```bash
|
|
sudo mkdir -p /etc/nix
|
|
sudo cp nix/nix.conf /etc/nix/nix.conf
|
|
sudo killall nix-daemon
|
|
```
|
|
|
|
Now you can enter our nix-shell, all the required packages will be downloaded but they will not pollute your environment outside of the shell:
|
|
|
|
```bash
|
|
nix-shell
|
|
```
|
|
|
|
You can use the traditional Rust development workflow:
|
|
|
|
```bash
|
|
cargo build # compile the project
|
|
cargo run # execute the project
|
|
cargo test # run the tests
|
|
cargo fmt # format the project, run it before any commit!
|
|
cargo clippy # run the linter, run it before any commit!
|
|
```
|
|
|
|
You can build the project with Nix by running:
|
|
|
|
```bash
|
|
nix-build
|
|
```
|
|
|
|
You can parallelize the build (if you use our nix.conf file, it is already automatically done).
|
|
To use all your cores when building a derivation use `-j`, and to build multiple derivations at once use `--max-jobs`.
|
|
The special value `auto` will be replaced by the number of cores of your computer.
|
|
An example:
|
|
|
|
```bash
|
|
nix-build -j $(nproc) --max-jobs auto
|
|
```
|
|
|
|
Our build has multiple parameters you might want to set:
|
|
- `release` build with release optimisations instead of debug
|
|
- `target allows` for cross compilation
|
|
- `compileMode` can be set to test or bench to build a unit test runner
|
|
- `git_version` to inject the hash to display when running `garage stats`
|
|
|
|
An example:
|
|
|
|
```bash
|
|
nix-build \
|
|
--arg release true \
|
|
--argstr target x86_64-unknown-linux-musl \
|
|
--argstr compileMode build \
|
|
--git_version $(git rev-parse HEAD)
|
|
```
|
|
|
|
*The result is located in `result/bin`. You can pass arguments to cross compile: check `.drone.yml` for examples.*
|
|
|
|
If you modify a `Cargo.toml` or regenerate any `Cargo.lock`, you must run `cargo2nix`:
|
|
|
|
```
|
|
cargo2nix -f
|
|
```
|
|
|
|
Many tools like rclone, `mc` (minio-client), or `aws` (awscliv2) will be available in your environment and will be useful to test Garage.
|
|
|
|
**This is the recommended method.**
|
|
|
|
## The Rust way
|
|
|
|
You need a Rust distribution installed on your computer.
|
|
The most simple way is to install it from [rustup](https://rustup.rs).
|
|
Please avoid using your package manager to install Rust as some tools might be outdated or missing.
|
|
|
|
Now, check your Rust distribution works by running the following commands:
|
|
|
|
```bash
|
|
rustc --version
|
|
cargo --version
|
|
rustfmt --version
|
|
clippy-driver --version
|
|
```
|
|
|
|
Now, you need to clone our git repository ([how to install git](https://git-scm.com/downloads)):
|
|
|
|
```bash
|
|
git clone https://git.deuxfleurs.fr/Deuxfleurs/garage
|
|
cd garage
|
|
```
|
|
|
|
You can now use the following commands:
|
|
|
|
```bash
|
|
cargo build # compile the project
|
|
cargo run # execute the project
|
|
cargo test # run the tests
|
|
cargo fmt # format the project, run it before any commit!
|
|
cargo clippy # run the linter, run it before any commit!
|
|
```
|
|
|
|
This is specific to our project, but you will need one last tool, `cargo2nix`.
|
|
To install it, run:
|
|
|
|
```bash
|
|
cargo install --git https://github.com/superboum/cargo2nix --branch main cargo2nix
|
|
```
|
|
|
|
You must use it every time you modify a `Cargo.toml` or regenerate a `Cargo.lock` file as follow:
|
|
|
|
```bash
|
|
cargo build # Rebuild Cargo.lock if needed
|
|
cargo2nix -f
|
|
```
|
|
|
|
It will output a `Cargo.nix` file which is a specific `Cargo.lock` file dedicated to Nix that is required by our CI
|
|
which means you must include it in your commits.
|
|
|
|
Later, to use our scripts and integration tests, you might need additional tools.
|
|
These tools are listed at the end of the `shell.nix` package in the `nativeBuildInputs` part.
|
|
It is up to you to find a way to install the ones you need on your computer.
|
|
|
|
**A global drawback of this method is that it is up to you to adapt your environment to the one defined in the Nix files.**
