# Selene 🌙



Selene is a project template to quickly set up LOVE2D to run moonscript instead of Lua,

*without* precompiling your `.moon` files to `.lua`



[MoonScript](https://github.com/leafo/moonscript) is extremely well suited to writing

games with its object-oriented approach!

# Installing



Selene works on Debian, Ubuntu, NixOS, and Windows. It should also work anywhere else

that LOVE2D runs!



## Install LOVE2D



Selene needs LOVE2D to be installed to run your game, and you can get the installer

for your platform at [the LOVE2D website](https://love2d.org).



## Create Your Game



You have two options when using Selene to create your game:



First (and most recommended) is to use this repo as a template repo. To do that, click

the button at the top right of the [github page](https://github.com/novafacing/selene)

that says "Use this template". That will create a new repo in your account that is a

copy of the Selene repo!



Second, is you can directly clone and modify this repo (or a fork of it), or just

download the zip file of this repo.



Once you have decided, just clone this repo (replace the link with your own if you

forked or used it as a template):



```sh

$ git clone https://github.com/novafacing/selene.git

```



Then, you will need to tell git to download the submodules for this repo that are needed

to run MoonScript without precompiling:



```sh

$ cd selene                               # Go into the git repository on your local machine

$ git submodule update --init --recursive # Update the git submodules for this repo

```



That's it! The conf.lua and main.lua take care of everything else to allow you to run

the game!



# Using



## First Run



Now that you have the repository set up, just run `love .` to start your game! There is 

a demo project already configured for you, and you should see something like this:



![A screenshot of the game running, displaying a moon image on the default LOVE2D light blue background](https://user-images.githubusercontent.com/30083762/180328998-579a5c85-3e95-4551-9018-b17c68414a76.png)



and you should be able to move around with the arrow keys.



## Writing Your Game



Now that you're all set up, write your game! Your source code should go in

[the src directory](src/), and you can add as many files as you want.

[The main file](src/main.moon) gives an example of how to require another file (in this

case `Game.moon`) to make your game's code modular. There is also a `Player` class

and a `Vector2` class to demonstrate how you might make your game even *more* modular.



# Building and Testing



## Build/Test Dependencies



You don't need any dependencies other than `love` to *run* your game, but you will to

build and test it.



You will need a couple dependencies:



* `lua >= 5.2`: You can probably install from your package manager ie

  `apt install lua5.2`

* `luarocks`: You can probably also install this from your package manager, or you can

  get it [here](https://luarocks.org/#quick-start)

* `act`: For local release builds, you will need to install

  [act](https://github.com/nektos/act)



Once you have `luarocks` installed, you can install the dependencies with:



```sh

$ luarocks make --dev

```



Don't forget the `--dev`, it's important!



## Testing



There is a build/test script `build.moon` provided that works automatically with the

template repo. You can invoke it to run tests like:



```sh

$ moon build.moon --test

```



It will run `busted` tests on all files matching a pattern, which defaults to 

`Test.+%.moon` but you can provide your own once you start writing your own tests like 

so:



```sh

$ moon build.moon src --test --pattern '.+Test%.moon'

```



## Release Builds



Release builds of projects will contain the bare minimum files to run, so for release

all `.moon` files will be compiled to `.lua`, all extra libraries are removed, and a

`.love` or `.exe` is produced. You can produce a release build by running:



```sh

$ act --artifact-server-path=release

```



This will spin up a pipeline, build your release, and output the files to `release`.



### Debugging Release Builds



The release build uses `build.moon` to compile all your `.moon` files to `.lua`.

If you have an issue, you can invoke it locally:



```sh

$ moon build.moon src

```



This will display any build errors encountered.



You can clean up the lua files from the source tree with:



```sh

$ moon build.moon src --clean

```



But be aware this will delete *all* `.lua` files in `src`!



# Notes



You'll notice that the embedded submodule is not moonscript master. Instead it is my own

fork. All I have done is replace the C dependency `lpeg` with a drop-in replacement

written in Lua, `lulpeg`. I'll update my MoonScript and LuLPeg repos from upstream

periodically, and feel free to file an issue if they breaking due to being outdated.

# Contributions and Bug Fixes



Bug fixes and contributions are welcome! If you find any issues, just open an Issue and I'll

take a look at it. I'm not going to formalize the process too much, because this is a tiny repo

and I don't expect I'll add too much code to it. Any improvements are likewise appreciated!



# Thanks



Thanks for using Selene! I hope it helps you create great games, and if you do, please open a PR to

add a gif or screenshot of your game and a link to it to this README so you can show it off!
