Franky Braem, the author of GLUEscript (successor of wxJavaScript) is working on POCO Javascript scripting engine (SpiderMonkey based) library. The engine is being developed to fit into the Poco::Script sandbox project, which already has a rudimentary Lua library. I looked over the code and liked it – it sure does look like a good old Poco-style C++ . Keep up the good work, Franky. Anyone interested in helping with Poco::Script, get in touch with Franky.
