## ⚙️ Installation
|
||||
|
||||
### Using [Aftman](https://github.com/lpghatguy/aftman)
|
||||
|
||||
The preferred way of installing Lune.
|
||||
|
||||
This will add `lune` to an `aftman.toml` file in the
|
||||
current directory, or create one if it does not exist.
|
||||
|
||||
```sh
|
||||
$ aftman add filiptibell/lune
|
||||
```
|
||||
|
||||
### From [GitHub Releases](https://github.com/filiptibell/lune/releases)
|
||||
|
||||
You can also download pre-built binaries for most
|
||||
systems directly from the linked GitHub Releases page.
|
||||
|
||||
## ✏️ Writing Lune Scripts
|
||||
|
||||
First things first, check out the examples of how to write a script in the [.lune](.lune) folder! <br>
|
||||
Lune has many useful built-in globals and APIs to use to interact with your system, and can do things
|
||||
such as read/write files, run external programs, serialize & deserialize json, and much more.
|
||||
|
||||
## 🏃 Running Lune Scripts
|
||||
|
||||
When you've written a script with either a `.lua` or `.luau` extension, you can run it:
|
||||
|
||||
```sh
|
||||
$ lune script-name
|
||||
```
|
||||
|
||||
This will look for the script `script_name` in a few locations:
|
||||
|
||||
- The current directory
|
||||
- The folder `lune` in the current directory, if it exists
|
||||
- The folder `.lune` in the current directory, if it exists
|
||||
|
||||
If you don't want Lune to look in sub-directories you can provide a full
|
||||
file path with the file extension included, instead of only the file name.
