From 267170167d52cab9e97f879d9127a1cf04f6bb58 Mon Sep 17 00:00:00 2001 From: Martin Peach Date: Tue, 15 Mar 2011 20:53:57 +0000 Subject: This is a version of Claude Heiland-Allen's lua for Pd. The objects are named pdlua and pdluax instead of lua and luax. So far it seems to work on linux. svn path=/trunk/externals/pdlua/; revision=15030 --- examples/complex-help.pd | 3 + examples/complex.lua | 30 ++ examples/complex.pd_lua | 12 +
