🤝 lemmy-help
Everyone needs help, so lemmy-help you
### What?
`lemmy-help` is a emmylua parser as well as a CLI which takes that parsed tree and converts it into vim help docs.
### Installation
- Using `cargo`
```bash
cargo install lemmy-help --features=cli
```
- Arch Linux
```bash
# Using yay
yay -S lemmy-help
# Using paru
paru -S lemmy-help
```
- Using releases
Check out the [release page](https://github.com/numToStr/lemmy-help/releases) for prebuild binaries available for different operating systems.
### Emmylua
To properly generate docs you should follow emmylua spec. The parser is capable of parsing most (not all) of the emmylua syntax. You can read the following doc which can give you the idea on how to properly write emmylua comments.
- [Writing emmylua docs](./emmylua.md)
### Usage
Using the CLI is simple just give it the path to the lua files; it will parse them and prints help doc onto **stdout**
```bash
lemmy-help /path/to/{first,second,third}.lua > doc/PLUGIN_NAME.txt
```
