Source code for Lua 5.3

[fosk]

When running Lua, always consider running it on the LuaJIT (http://luajit.org/). It's extremely fast, portable and lightweight JIT compiler for Lua, although it only supports Lua 5.1.

The performance improvements are incredible, and it allows you to write inline C code thanks to the FFI library (declaring it like this https://github.com/Mashape/kong/blob/master/kong/plugins/fil..., and invoking it like this https://github.com/Mashape/kong/blob/master/kong/plugins/fil...)

Seconded. LuaJIT FFI is just awesome. Check out the motivating examples: http://luajit.org/ext_ffi.html

BTW, does anyone have recent benchmarks comparing LuaJIT against new versions of the Javascript JITs?

[aleksi]

There are some Lua 5.2 extensions: http://luajit.org/extensions.html

You are restricted to making C declarations. You can't write inline C code. You can however can create and use C types in Lua.

What's the point of posting this? Pointing out how small and elegant a real world language implementation can be?

[scrollaway]

I'm happy with anything that gives Lua more exposure. It's a pretty language and it is so damn small, fast and embeddable.

Too many developers are using Javascript in places where Lua would be a far more appropriate option. Embedding, especially.

[vmorgulis]

Yes and the design of the source code browsing (by column).

[mrdrozdov]

What's a "real world language"?

Why not reimplement lua in lua?

[catwell]

It has been done, several times.

A popular version is http://yueliang.luaforge.net/, although it only supports old Luas (5.0 and 5.1).

[corysama]

It would be fun to reimplement Lua in http://terralang.org/
