I’ve been wanting to do this for a while, but always procrastinated on it. We’ve been using Clap since the 2.0 rewrite, but Clap is known to be a fairly heavy library. Since Rustlings is usually peoples’ first contact with a Rust compilation, I think it’s in our best interests that this complation is as fast as possible. In effect, replacing Clap with the smaller, structopt-style `argh` reduces the amount of crates needing to be compiled from 82 to 60.
I also think this makes the code way easier to read, we don’t need to use Clap’s methods anymore, but can switch over to using pure Rust methods, e.g., switches are booleans, options are Option<String>s or the like, and subcommands are just structs.
1.
`rustlings list` should now display more than just the exercise names.
Information such as file paths and exercises statuses should be displayed.
The `--paths` option limits the displayed fields to only the path names; while the `--names`
option limits the displayed fields to only exercise names.
You can also control which exercises are displayed, by using the `--filter` option, or
the `--solved` or `--unsolved` flags.
Some use cases:
- Fetching pending exercise files with the keyword "conversion" to pass to my editor:
```sh
vim $(rustlings list --filter "conversion" --paths --unsolved)
```
- Fetching exercise names with keyword "conversion" to pass to `rustlings run`:
```sh
for exercise in $(rustlings list --filter "conversion" --names)
do
rustlings run ${exercise}
done
```
2.
This should also fix#465, and will likely fix#585, as well.
That bug mentioned in those issues has to do with the way the `watch` command handler fetches the pending exercises.
Going forward, the least recently updated exercises along with all the other exercises in a pending state are fetched.
This new feature can be accessed by invoking rustlings with --nocapture.
Both unit and integration tests added.
