```
cargo install eonfmt
```
You can format individual files, or a whole folder recursively.
When given a folder, only `.eon` files will be formatted,
and `.gitignore` will be respected.
```
eonfmt file.rs
eonfmt folder/
eonfmt .
```
You can also check whether or not files are formatted:
```
eonfmt --check .
```
