## 6.0.1 (2024-07-04)
|
||||
|
||||
Small exercise improvements and fixes.
|
||||
Most importantly, fixed that the exercise `clippy1` was already solved 😅
|
||||
|
||||
<a name="6.0.0"></a>
|
||||
|
||||
## 6.0.0 (2024-07-03)
|
||||
|
||||
This release is the result of a complete rewrite to deliver a ton of new features and improvements ✨
|
||||
The most important changes are highlighted below.
|
||||
|
||||
### Installation
|
||||
|
||||
The installation has been simplified a lot!
|
||||
To install Rustlings after installing Rust, all what you need to do now is running the following command:
|
||||
|
||||
```bash
|
||||
cargo install rustlings
|
||||
```
|
||||
|
||||
Yes, this means that Rustlings is now on [crates.io](https://crates.io/crates/rustlings) 🎉
|
||||
|
||||
You can read about the motivations of this change in [this issue](https://github.com/rust-lang/rustlings/issues/1919).
|
||||
|
||||
### UI/UX
|
||||
|
||||
- The UI is now responsive when the terminal is resized.
|
||||
- The progress bar was moved to the bottom so that you can always see your progress and the current exercise to work on.
|
||||
- The current exercise path is now a terminal link. It will open the exercise file in your default editor when you click on it.
|
||||
- A small prompt is now always shown at the bottom. It allows you to choose an action by entering a character. For example, entering `h` will show you the hint of the current exercise.
|
||||
- The comment "I AM NOT DONE!" doesn't exist anymore. Instead of needing to remove it to go to the next exercise, you need to enter `n` in the terminal.
|
||||
|
||||
### List mode
|
||||
|
||||
A list mode was added using [Ratatui](https://ratatui.rs).
|
||||
You can enter it by entering `l` in the watch mode.
|
||||
It offers the following features:
|
||||
|
||||
- Browse all exercises and see their state (pending/done).
|
||||
- Filter exercises based on their state (pending/done).
|
||||
- Continue at another exercise. This allows you to skip some exercises or go back to previous ones.
|
||||
- Reset an exercise so you can start over and revert your changes.
|
||||
|
||||
### Solutions
|
||||
|
||||
After finishing an exercise, a solution file will be available and Rustlings will show you its path in green.
|
||||
This allows you to compare your solution with an idiomatic solution and maybe learn about other ways to solve a problem.
|
||||
|
||||
While writing the solutions, all exercises have been polished 🌟
|
||||
For example, every exercise now contains `TODO` comments to highlight what the user needs to change and where.
|
||||
|
||||
### LSP support out of the box
|
||||
|
||||
Instead of creating a `project.json` file using `rustlings lsp`, Rustlings now works with a `Cargo.toml` file out of the box.
|
||||
No actions are needed to activate the language server `rust-analyzer`.
|
||||
|
||||
This should avoid issues related to the language server or to running exercises, especially the ones with Clippy.
|
||||
|
||||
### Clippy
|
||||
|
||||
Clippy lints are now shown on all exercises, not only the Clippy exercises 📎
|
||||
Make Clippy your friend from early on 🥰
|
||||
|
||||
### Third party exercises
|
||||
|
||||
Rustlings now supports third-party exercises!
|
||||
|
||||
Do you want to create your own set of Rustlings exercises to focus on some specific topic?
|
||||
Or do you want to translate the original Rustlings exercises?
|
||||
Then follow the link to the guide about [third-party exercises](THIRD_PARTY_EXERCISES.md)!

### 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 `argh` CLI that connects to most of the other source files.
|
||||
|
||||
<a name="addex"></a>
|
||||
### 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` and `rustlings watch`.
|
||||
|
||||
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`. If you're working on a Clippy exercise, use `mode = "clippy"`.
|
||||
|
||||
That's all! Feel free to put up a pull request.

### Pull Requests
|
||||
## 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:
|
||||
You are welcome to open a pull request, but unless it is small and trivial, **please open an issue to discuss your idea first** 🙏🏼
|
||||
|
||||
#### Write correct commit messages
|
||||
Opening a pull request is as easy as forking the repository and committing your changes.
|
||||
If you need any help with it or face any Git related problems, don't hesitate to ask for help 🤗
|
||||
|
||||
We follow the [Conventional Commits](https://www.conventionalcommits.org/en/v1.0.0-beta.4/)
|
||||
specification.
|
||||
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:
|
||||
It may take time to review your pull request.
|
||||
Please be patient 😇
|
||||
|
||||
```
|
||||
feat: add foobar1.rs exercise
|
||||
When updating an exercise, check if its solution needs to be updated.
|
||||
|
||||
## Adding An 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`.
|
||||
- In the exercise, add a `// TODO: …` comment where user changes are required.
|
||||
- Add a solution at `solutions/yourTopic/yourTopicN.rs` with comments explaining it.
|
||||
- Add the [metadata for your exercise](#exercise-metadata) in the `rustlings-macros/info.toml` file.
|
||||
- Make sure your exercise runs with `rustlings run yourTopicN`.
|
||||
- [Open a pull request](#pull-requests).
|
||||
|
||||
### Exercise Metadata
|
||||
|
||||
The exercise metadata should contain the following:
|
||||
|
||||
```toml
|
||||
[[exercises]]
|
||||
name = "yourTopicN"
|
||||
dir = "yourTopic"
|
||||
hint = """
|
||||
A useful (multi-line) hint for your exercise.
|
||||
Include links to a section in The Book or a documentation page."""
|
||||
```
|
||||
|
||||
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. Please be patient, it may take some time
|
||||
for this to happen!
|
||||
If your exercise doesn't contain any test, add `test = false` to the exercise metadata.
|
||||
But adding tests is recommended.

Greetings and welcome to `rustlings`. This project contains small exercises to get you used to reading and writing Rust code. This includes reading and responding to compiler messages!
|
||||
Greetings and welcome to Rustlings.
|
||||
This project contains small exercises to get you used to reading and writing Rust code.
|
||||
This includes reading and responding to compiler messages!
|
||||
|
||||
_...looking for the old, web-based version of Rustlings? Try [here](https://github.com/rust-lang/rustlings/tree/rustlings-1)_
|
||||
It is recommended to do the Rustlings exercises in parallel to reading [the official Rust book](https://doc.rust-lang.org/book/), the most comprehensive resource for learning Rust 📚️
|
||||
|
||||
Alternatively, for a first-time Rust learner, there are several other resources:
|
||||
|
||||
- [The Book](https://doc.rust-lang.org/book/index.html) - The most comprehensive resource for learning Rust, but a bit theoretical sometimes. You will be using this along with Rustlings!
|
||||
- [Rust By Example](https://doc.rust-lang.org/rust-by-example/index.html) - Learn Rust by solving little exercises! It's almost like `rustlings`, but online
|
||||
[Rust By Example](https://doc.rust-lang.org/rust-by-example/) is another recommended resource that you might find helpful.
|
||||
It contains code examples and exercises similar to Rustlings, but online.
|
||||
|
||||
## Getting Started
|
||||
|
||||
_Note: If you're on MacOS, make sure you've installed Xcode and its developer tools by typing `xcode-select --install`._
|
||||
_Note: If you're on Linux, make sure you've installed gcc. Deb: `sudo apt install gcc`. Yum: `sudo yum -y install gcc`._
|
||||
### Installing Rust
|
||||
|
||||
You will need to have Rust installed. You can get it by visiting <https://rustup.rs>. This'll also install Cargo, Rust's package/project manager.
|
||||
Before installing Rustlings, you need to have _Rust installed_.
|
||||
Visit [www.rust-lang.org/tools/install](https://www.rust-lang.org/tools/install) for further instructions on installing Rust.
|
||||
This'll also install _Cargo_, Rust's package/project manager.
|
||||
|
||||
## MacOS/Linux
|
||||
> 🐧 If you're on Linux, make sure you've installed `gcc` (for a linker).
|
||||
>
|
||||
> Deb: `sudo apt install gcc`.
|
||||
> Dnf: `sudo dnf install gcc`.
|
||||
|
||||
Just run:
|
||||
> 🍎 If you're on MacOS, make sure you've installed Xcode and its developer tools by running `xcode-select --install`.
|
||||
|
||||
### Installing Rustlings
|
||||
|
||||
The following command will download and compile Rustlings:
|
||||
|
||||
```bash
|
||||
curl -L sh.rustlings.cool | bash
|
||||
cargo install rustlings
|
||||
```
|
||||
|
||||
Or if you want it to be installed to a different path:
|
||||
<details>
|
||||
<summary><strong>If the installation fails…</strong> (<em>click to expand</em>)</summary>
|
||||
|
||||
- Make sure you have the latest Rust version by running `rustup update`
|
||||
- Try adding the `--locked` flag: `cargo install rustlings --locked`
|
||||
- Otherwise, please [report the issue](https://github.com/rust-lang/rustlings/issues/new)
|
||||
|
||||
</details>
|
||||
|
||||
### Initialization
|
||||
|
||||
After installing Rustlings, run the following command to initialize the `rustlings/` directory:
|
||||
|
||||
```bash
|
||||
curl -L sh.rustlings.cool | bash -s mypath/
|
||||
rustlings init
|
||||
```
|
||||
|
||||
This will install Rustlings and give you access to the `rustlings` command. Run it to get started!
|
||||
|
||||
### Nix
|
||||
|
||||
Basically: Clone the repository at the latest tag, finally run `nix develop` or `nix-shell`.
|
||||
Now, go into the newly initialized directory and launch Rustlings for further instructions on getting started with the exercises:
|
||||
|
||||
```bash
|
||||
# find out the latest version at https://github.com/rust-lang/rustlings/releases/latest (on edit 5.6.1)
|
||||
git clone -b 5.6.1 --depth 1 https://github.com/rust-lang/rustlings
|
||||
cd rustlings
|
||||
# if nix version > 2.3
|
||||
nix develop
|
||||
# if nix version <= 2.3
|
||||
nix-shell
|
||||
cd rustlings/
|
||||
rustlings
|
||||
```
|
||||
|
||||
## Windows
|
||||
## Working environment
|
||||
|
||||
In PowerShell (Run as Administrator), set `ExecutionPolicy` to `RemoteSigned`:
|
||||
### Editor
|
||||
|
||||
```ps1
|
||||
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
|
||||
```
|
||||
Our general recommendation is [VS Code](https://code.visualstudio.com/) with the [rust-analyzer plugin](https://marketplace.visualstudio.com/items?itemName=rust-lang.rust-analyzer).
|
||||
But any editor that supports [rust-analyzer](https://rust-analyzer.github.io/) should be enough for working on the exercises.
|
||||
|
||||
Then, you can run:
|
||||
### Terminal
|
||||
|
||||
```ps1
|
||||
Start-BitsTransfer -Source https://ps1.rustlings.cool -Destination $env:TMP/install_rustlings.ps1; Unblock-File $env:TMP/install_rustlings.ps1; Invoke-Expression $env:TMP/install_rustlings.ps1
|
||||
```
|
||||
While working with Rustlings, please use a modern terminal for the best user experience.
|
||||
The default terminal on Linux and Mac should be sufficient.
|
||||
On Windows, we recommend the [Windows Terminal](https://aka.ms/terminal).
|
||||
|
||||
To install Rustlings. Same as on MacOS/Linux, you will have access to the `rustlings` command after it. Keep in mind that this works best in PowerShell, and any other terminals may give you errors.
|
||||
|
||||
If you get a permission denied message, you might have to exclude the directory where you cloned Rustlings in your antivirus.
|
||||
|
||||
## Browser
|
||||
|
||||
[](https://gitpod.io/#https://github.com/rust-lang/rustlings)
|
||||
|
||||
[](https://github.com/codespaces/new/?repo=rust-lang%2Frustlings&ref=main)
|
||||
|
||||
## Manually
|
||||
|
||||
Basically: Clone the repository at the latest tag, run `cargo install --path .`.
|
||||
|
||||
```bash
|
||||
# find out the latest version at https://github.com/rust-lang/rustlings/releases/latest (on edit 5.6.1)
|
||||
git clone -b 5.6.1 --depth 1 https://github.com/rust-lang/rustlings
|
||||
cd rustlings
|
||||
cargo install --force --path .
|
||||
```
|
||||
|
||||
If there are installation errors, ensure that your toolchain is up to date. For the latest, run:
|
||||
|
||||
```bash
|
||||
rustup update
|
||||
```
|
||||
|
||||
Then, same as above, run `rustlings` to get started.
|
||||
If you use VS Code, the builtin terminal should also be fine.
|
||||
|
||||
## Doing exercises
|
||||
|
||||
The exercises are sorted by topic and can be found in the subdirectory `rustlings/exercises/<topic>`. For every topic there is an additional README file with some resources to get you started on the topic. We really recommend that you have a look at them before you start.
|
||||
The exercises are sorted by topic and can be found in the subdirectory `exercises/<topic>`.
|
||||
For every topic, there is an additional `README.md` file with some resources to get you started on the topic.
|
||||
We highly recommend that you have a look at them before you start 📚️
|
||||
|
||||
The task is simple. Most exercises contain an error that keeps them from compiling, and it's up to you to fix it! Some exercises are also run as tests, but rustlings handles them all the same. To run the exercises in the recommended order, execute:
|
||||
Most exercises contain an error that keeps them from compiling, and it's up to you to fix it!

Search for `TODO` and `todo!()` to find out what you need to change.
|
||||
Ask for hints by entering `h` in the _watch mode_ 💡
|
||||
|
||||
This will try to verify the completion of every exercise in a predetermined order (what we think is best for newcomers). It will also rerun automatically every time you change a file in the `exercises/` directory. If you want to only run it once, you can use:
|
||||
### Watch Mode
|
||||
|
||||
```bash
|
||||
rustlings verify
|
||||
```
|
||||
After [initialization](#initialization), Rustlings can be launched by simply running the command `rustlings`.
|
||||
|
||||
This will do the same as watch, but it'll quit after running.
|
||||
This will start the _watch mode_ which walks you through the exercises in a predefined order (what we think is best for newcomers).
|
||||
It will rerun the current exercise automatically every time you change the exercise's file in the `exercises/` directory.
|
||||
|
||||
In case you want to go by your own order, or want to only verify a single exercise, you can run:
|
||||
<details>
|
||||
<summary><strong>If detecting file changes in the <code>exercises/</code> directory fails…</strong> (<em>click to expand</em>)</summary>
|
||||
|
||||
```bash
|
||||
rustlings run myExercise1
|
||||
```
|
||||
> You can add the **`--manual-run`** flag (`rustlings --manual-run`) to manually rerun the current exercise by entering `r` in the watch mode.
|
||||
>
|
||||
> Please [report the issue](https://github.com/rust-lang/rustlings/issues/new) with some information about your operating system and whether you run Rustlings in a container or virtual machine (e.g. WSL).
|
||||
|
||||
Or simply use the following command to run the next unsolved exercise in the course:
|
||||
</details>
|
||||
|
||||
```bash
|
||||
rustlings run next
|
||||
```
|
||||
### Exercise List
|
||||
|
||||
In case you get stuck, you can run the following command to get a hint for your
|
||||
exercise:
|
||||
In the [watch mode](#watch-mode) (after launching `rustlings`), you can enter `l` to open the interactive exercise list.
|
||||
|
||||
```bash
|
||||
rustlings hint myExercise1
|
||||
```
|
||||
The list allows you to…
|
||||
|
||||
You can also get the hint for the next unsolved exercise with the following command:
|
||||
- See the status of all exercises (done or pending)
|
||||
- `c`: Continue at another exercise (temporarily skip some exercises or go back to a previous one)
|
||||
- `r`: Reset status and file of an exercise (you need to _reload/reopen_ its file in your editor afterwards)
|
||||
|
||||
```bash
|
||||
rustlings hint next
|
||||
```
|
||||
|
||||
To check your progress, you can run the following command:
|
||||
|
||||
```bash
|
||||
rustlings list
|
||||
```
|
||||
|
||||
## Testing yourself
|
||||
|
||||
After every couple of sections, there will be a quiz that'll test your knowledge on a bunch of sections at once. These quizzes are found in `exercises/quizN.rs`.
|
||||
|
||||
## Enabling `rust-analyzer`
|
||||
|
||||
Run the command `rustlings lsp` which will generate a `rust-project.json` at the root of the project, this allows [rust-analyzer](https://rust-analyzer.github.io/) to parse each exercise.
|
||||
See the footer of the list for all possible keys.
|
||||
|
||||
## Continuing On
|
||||
|
||||
Once you've completed Rustlings, put your new knowledge to good use! Continue practicing your Rust skills by building your own projects, contributing to Rustlings, or finding other open-source projects to contribute to.

|
||||
On [CodeCrafters](https://codecrafters.io/rust) you can get some quality practice through recreating different technologies from scratch in Rust (e.g Build your own BitTorrent, HTTP Server, SQLite, etc).
|
||||
## Third-Party Exercises
|
||||
|
||||
Do you want to create your own set of Rustlings exercises to focus on some specific topic?
|
||||
Or do you want to translate the original Rustlings exercises?
|
||||
Then follow the link to the guide about [third-party exercises](THIRD_PARTY_EXERCISES.md)!
|
||||
|
||||
## Uninstalling Rustlings
|
||||
|
||||
If you want to remove Rustlings from your system, there are two steps. First, you'll need to remove the exercises folder that the install script created
|
||||
for you:
|
||||
|
||||
```bash
|
||||
rm -rf rustlings # or your custom folder name, if you chose and or renamed it
|
||||
```
|
||||
|
||||
Second, run `cargo uninstall` to remove the `rustlings` binary:
|
||||
If you want to remove Rustlings from your system, run the following command:
|
||||
|
||||
```bash
|
||||
cargo uninstall rustlings
|
||||
```
|
||||
|
||||
Now you should be done!

# Third-Party Exercises
|
||||
|
||||
The support of Rustlings for third-party exercises allows you to create your own set of Rustlings exercises to focus on some specific topic.
|
||||
You could also offer a translatation of the original Rustlings exercises as third-party exercises.
|
||||
|
||||
## Getting started
|
||||
|
||||
To create third-party exercises, install Rustlings and run `rustlings dev new PROJECT_NAME`.
|
||||
This command will, similar to `cargo new PROJECT_NAME`, create a template directory called `PROJECT_NAME` with all what you need to get started.
|
||||
|
||||
Read the comments in the generated `info.toml` file to understand its format.
|
||||
It allows you to set a custom welcome and final message and specify the metadata of every exercise.
|
||||
|
||||
## Create an exercise
|
||||
|
||||
Here is an example of the metadata of one file:
|
||||
|
||||
```toml
|
||||
[[exercises]]
|
||||
name = "intro1"
|
||||
hint = """
|
||||
To finish this exercise, you need to …
|
||||
This link might help you …"""
|
||||
```
|
||||
|
||||
After entering this in `info.toml`, create the file `intro1.rs` in the `exercises/` directory.
|
||||
The exercise needs to contain a `main` function, but it can be empty.
|
||||
Adding tests is recommended.
|
||||
Look at the official Rustlings exercises for inspiration.
|
||||
|
||||
You can optionally add a solution file `intro1.rs` to the `solutions/` directory.
|
||||
|
||||
Now, run `rustlings dev check`.
|
||||
It will tell you about any issues with your exercises.
|
||||
For example, it will tell you to run `rustlings dev update` to update the `Cargo.toml` file to include the new exercise `intro1`.
|
||||
|
||||
`rustlings dev check` will also run your solutions (if you have any) to make sure that they run successfully.
|
||||
|
||||
That's it!
|
||||
You finished your first exercise 🎉
|
||||
|
||||
## Publish
|
||||
|
||||
Now, add more exercises and publish them as a Git repository.
|
||||
|
||||
Users just have to clone that repository and run `rustlings` in it to start working on your set of exercises just like the official ones.
|
||||
|
||||
One difference to the official exercises is that the solution files will not be hidden until the user finishes an exercise.
|
||||
But you can trust the users to not look at the solution too early 😉
|
||||
|
||||
## Share
|
||||
|
||||
After publishing your set of exercises, open an issue or a pull request in the official Rustlings repository to link to your project in the README 😃

Namely, being generic requires taking great care to specify over which types a generic type is actually considered valid.
