Projects / HGL Suite

HGL Suite

HGL is a compiler/interpreter suite for developing images. It features its own simple but powerful language, Lua integration, output in various formats as well as 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.

Feedback, help & testers URGENTLY needed 09 Aug 2013 07:36

As HGL gradually more and more into a stable source base it gets harder for the currently only one developer to maintain all. Therefore help is needed at all parts, like * testing * C++ programming * LUA programming * translation * documentation/maintaining the web site * porting to other platforms (Windows, POSIX like platforms) Many parts are good for beginners too. I will provide all help neccessary to get a smooth start. So feel free and join HGL to get it advanced.
