hi list,
there's a new pdlua release on deken now, which - besides other stuff - adds support for signal rate processing and graphics routines!
please note that i'm just the messenger (and uploader) here and will simply quote albert's message for the 0.12.0 major release on https://github.com/agraef/pd-lua/releases:
Special thanks are due to Timothy Schoen who contributed the bulk of this release. His new graphics routines let you use a Lua object as a graphical canvas on which you can draw graphical shapes such as ellipses, rectangles, paths, Bezier paths, and text. It also supports animations and mouse interaction. Please check the graphics subpatch in the main pdlua-help patch for details. Tim also added signal inlet/outlet support and real-time signal processing (see examples/sig-example), and the possibility to store creation arguments in a Lua object (see examples/gui-example).
happy patching (and scripting), ben
