lemons is a game framework that's built on haxe that provides.. well what a game framework should, a framework to build your games on
there isnt a haxelib version avalible yet so you'll have to follow the installing from github instructions
go to your bash shell of choice or command prompt and run
cd <whereever you want to install lemons in>
git clone --recurse-submodules https://github.com/LemonsFramework/lemons.git
cd lemons
haxelib dev .
since haxelib git doesent recursivley clone submodules, you have to use this janky fix
you will need to follow the building instructions at the bottom if you're installing it from github
again, go to your bash shell of choice or command prompt and run haxelib run lemons rebuild. oh, and you'll have to have cmake installed.
