## Contributing to Rustlings
|
|
|
|
First off, thanks for taking the time to contribute!! ❤️
|
|
|
|
### Quick Reference
|
|
|
|
I want to...
|
|
|
|
_add an exercise! ➡️ [read this](#addex) and then [open a Pull Request](#prs)_
|
|
|
|
_update an outdated exercise! ➡️ [open a Pull Request](#prs)_
|
|
|
|
_report a bug! ➡️ [open an Issue](#issues)_
|
|
|
|
_fix a bug! ➡️ [open a Pull Request](#prs)_
|
|
|
|
_implement a new feature! ➡️ [open an Issue to discuss it first, then a Pull Request](#issues)_

### Working on the source code
|
|
|
|
`rustlings` is basically a glorified `rustc` wrapper. Therefore the source code
|
|
isn't really that complicated since the bulk of the work is done by `rustc`.
|
|
`src/main.rs` contains a simple `clap` CLI that loads from `src/verify.rs` and `src/run.rs`.
|
|
|
|

|
|
### Adding an exercise
|
|
|
|
The first step is to add the exercise! Name the file `exercises/yourTopic/yourTopicN.rs`, make sure to
|
|
put in some helpful links, and link to sections of the book in `exercises/yourTopic/README.md`.
|
|
|
|
Next make sure it runs with `rustlings`. The exercise metadata is stored in `info.toml`, under the `exercises` array. The order of the `exercises` array determines the order the exercises are run by `rustlings verify`.
|
|
|
|
Add the metadata for your exercise in the correct order in the `exercises` array. If you are unsure of the correct ordering, add it at the bottom and ask in your pull request. The exercise metadata should contain the following:
|
|
```diff
|
|
...
|
|
+ [[exercises]]
|
|
+ name = "yourTopicN"
|
|
+ path = "exercises/yourTopic/yourTopicN.rs"
|
|
+ mode = "compile"
|
|
+ hint = """
|
|
+ Some kind of useful hint for your exercise."""
|
|
...
|
|
```
|
|
|
|
The `mode` attribute decides whether Rustlings will only compile your exercise, or compile and test it. If you have tests to verify in your exercise, choose `test`, otherwise `compile`.
|
|
|
|
That's all! Feel free to put up a pull request.

You can open an issue [here](https://github.com/rust-lang/rustlings/issues/new).
|
|
If you're reporting a bug, please include the output of the following commands:
|

|
|
- `rustc --version`
|
|
- `rustlings --version`
|

### Pull Requests
|
|
|
|
Opening a pull request is as easy as forking the repository and committing your
|
|
changes. There's a couple of things to watch out for:
|
|
|
|
#### Write correct commit messages
|
|
|
|
We follow the [Conventional Commits](https://www.conventionalcommits.org/en/v1.0.0-beta.4/)
|
|
specification, because it makes it easier to generate changelogs automatically.
|
|
This means that you have to format your commit messages in a specific way. Say
|
|
you're working on adding a new exercise called `foobar1.rs`. You could write
|
|
the following commit message:
|
|
|
|
```
|
|
feat: Add foobar1.rs exercise
|
|
```
|
|
|
|
If you're just fixing a bug, please use the `fix` type:
|
|
|
|
```
|
|
fix(verify): Make sure verify doesn't self-destruct
|
|
```
|
|
|
|
The scope within the brackets is optional, but should be any of these:
|
|
|
|
- `installation` (for the installation script)
|
|
- `cli` (for general CLI changes)
|
|
- `verify` (for the verification source file)
|
|
- `watch` (for the watch functionality source)
|
|
- `run` (for the run functionality source)
|
|
- `EXERCISENAME` (if you're changing a specific exercise, or set of exercises,
|
|
substitute them here)
|
|
|
|
When the commit also happens to close an existing issue, link it in the message
|
|
body:
|
|
|
|
```
|
|
fix: Update foobar
|
|
|
|
closes #101029908
|
|
```
|
|
|
|
If you're doing simple changes, like updating a book link, use `chore`:
|
|
|
|
```
|
|
chore: Update exercise1.rs book link
|
|
```
|
|
|
|
If you're updating documentation, use `docs`:
|
|
|
|
```
|
|
docs: Add more information to Readme
|
|
```
|
|
|
|
If, and only if, you're absolutely sure you want to make a breaking change
|
|
(please discuss this beforehand!), add an exclamation mark to the type and
|
|
explain the breaking change in the message body:
|
|
|
|
```
|
|
fix!: Completely change verification
|
|
|
|
BREAKING CHANGE: This has to be done because lorem ipsum dolor
|
|
```
|
|
|
|
#### Pull Request Workflow
|
|
|
|
Once you open a Pull Request, it may be reviewed or labeled (or both) until
|
|
the maintainers accept your change. Then, [bors](https://github.com/bors) will
|
|
run the test suite with your changes and if it's successful, automatically
|
|
merge it in!
