Lua Version

[jprovan]

What version of Lua is Girder using ... 5.0 or 5.1 ? If it is 5.0, are there plans on taking it to 5.1 ?

[Rob H]

Girder is using version 5.0.2

There are no plans to use 5.1 with Girder 5 - there are (or at least were the last time we looked at this) issues with Luacom and luathread when used with 5.1 which are the major reasons for not moving to 5.1.

I'd love to have Lua 5.1 available in Girder, but it's very unlikely to happen before version 6 of Girder.

Thanks for the quick reply, but that begs to ask the next question. When is Girder 6 planned ?

Girder 5 just went gold mid-august. I doubt if the developers are itching to re-write it so soon.

I'd love to have Lua 5.1 available in Girder, ...What does Lua 5.1 have over 5.0 that's so irresistible?

[Rob H]

There are a number of minor syntactic changes e.g. the use of ... instead of arg in the body of a function, # as sugar for table.getn(), the select function etc.

However the main reason I would like Lua 5.1 is so that we could use LuaJIT to speed up execution of Lua on Win32 machines to almost C level performance
