## 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 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:
Some exercises contain tests that need to pass for the exercise to be done.
### Watch Mode
To run the exercises, launch Rustlings:
```bash
rustlings
```
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.
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>
```bash
rustlings run EXERCISE_NAME
```
**If detecting file changes in the `exercises/` directory fails…** (_click to expand_)
Or simply use the following command to run the next pending exercise in the course:
</summary>
```bash
rustlings run
```
You can add the `--manual-run` flag (`rustlings --manual-run`) to manually rerun the current exercise by entering `r` or `run` in the watch mode.
In case you get stuck, you can run the following command to get a hint for your exercise:
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).
```bash
rustlings hint EXERCISE_NAME
```
</details>
You can also get the hint for the next pending exercise with the following command:
### Exercise List
```bash
rustlings hint
```
In the [watch mode](#watch-mode) (after launching `rustlings`), you can enter `l` or `list` to open the interactive exercise list.
The list allows you to…
- See the status of all exercises (done or pending)
- `c`: Continue at another exercise (temporarelly skip some exercises or go back to a previous one)
- `r`: Reset the status and file of an exercise (you need to reload/reopen its file in your editor afterwards)
See the footer of the list for all possible keys.
