Objective Lua is, right now, an interesting toy but needs a lot of work to actually be usable. Currently the requirement that emitted code is always in the same order as the source code (to make the debug information work) is forcing me to bend the object model horribly, with fairly repulsive results. Someone not long ago suggested that this problem could be solved by postprocessing stack traces, which would allow the object model to be considerably simplified and generally made saner. Plus, there are some bugs to be fixed; things like my Exciting Hack to make @try...@catch work causes the contents of ... to change inside the exception handler, etc; not to mention fundamental issues in catching untyped exceptions. Bolting it on to an Objective C backend would appear to make a great deal of sense but there seem to be conceptual impedance mismatches between LuaCocoa and Objective Lua at the moment. Hopefully changing olua's object model could solve these. I suspect that currently Objective Lua's main usefulness is that it contains a fairly complete recursive descent Lua parser (albeit with a few shortcuts) that can be plausibly ripped out and used in other projects. -- ┌─── ｄｇ＠ｃｏｗｌａｒｋ．ｃｏｍ ───── http://www.cowlark.com ───── │ "Thou who might be our Father, who perhaps may be in Heaven, hallowed │ be Thy Name, if Name Thou hast and any desire to see it hallowed..." │ --- _Creatures of Light and Darkness_, Roger Zelazny
