EGSL is a small interpreter which can execute Lua scripts. It includes some functions for fast and easy game development. These are image manipulation functions, functions for 2D drawing, sound and music, input via mouse, keyboard, and joypad, and some helper functions. The engine is based on SDL, SDL_gfx, and SDL_mixer, and additionally on SDL_image on Haiku-OS.
HGL is a compiler/interpreter suite for developing images. It features its own simple but powerful language, an output format configurable by plugins, runtime input handled by plugins, and easy integration into various environments like Web servers or graphical applications. The input is taken from a source file, which has to be compiled for quick and frequent access by the interpreter. An interpreter then runs the compiled files, takes input from custom plugins (if neccessary), and outputs its result via custom plugins.
