A set of useful Lua classes & libraries for projects using loaf: http://danomatika.com/code/loaf
loaf is an interpreter for openFrameworks which allows you to write OF applications in the Lua scripting language. This means you can quickly create using openFrameworks but without having to compile C++ or use a heavy IDE like Xcode or Visual Studio. A built-in OSC (Open Sound Control) server enables loaf to communicate natively with other creative coding and music applications over a network connection.

The ingredients are a mix of traditional Lua tables and reusable loaf class objects. The naming convention followed is for classes to begin with uppercase letters.
- hui: the "Hooey UI", simple window & view hierarchy for UIs based on Apple's UIKit
- panel: a simple vertical gui panel inspired by ofxGui, uses hui
- resources: a loaf resource manager
- SimpleSprite: simple sprite animation class using a sprite sheet
- Scaler: a loaf 2d render scaler class
- Timer: a simple millisecond timer class
- Warper: a quad warper using an fbo
- options: super simple commandline options parser
Documentation can be found in the source files and in examples.
Examples are found on the examples directory. They can be run by either drag & dropping the Lua scripts onto loaf or via the commandline:
loaf examples/huitest.lua
Screenshots:
huitest: multiple hui.Windows with enclosed hui.Views, active window has a red border
testpanel: panel with label and sliders, inspired by ofxGui
testwarper: quad warper in edit mode
Download or clone this repository and place the .lua files and/or subfolders you want to use into a folder in your project, say "libs". To use the loaf resource manager, you might have the following project layout:
project/libs/resources.lua
project/assets/hellokitty.png
project/main.lua
In main.lua, you can then import and use resources.lua via the require keyword:
local resources = "libs.resources"
local image = resources.add("hellokitty", "assets/hellokitty.png")
Note the "libs.resources" which includes the "libs" subfolder. The same is true for libraries within a folder as require will automatically search for an init.lua file as well.
