Lune

A pure Go implementation of the Lua virtual machine (v5.2).

Goals / Features

• Run Lua code. Make every pure Lua code (without C calls outside of the standard libs) work as expected. Every lua binary chunk compiled using luac should work on Lune, unless it relies on the C API.
• Implement the Lua standard libraries in Go. Make it transparent to Lua code.
• Embeddable. This is a Go package, it can be embedded in any Go application.
• Go-friendly. Just like Lua is the dynamic companion to C, Lune tries to bring this Batman and Robin camaraderie to Go. This means registering Go functions to be callable from Lua-on-Lune. This may be a port of the C API to Go, or something else that does more or less the same thing.

Current status

Dormant. Unstable. Ugly. Unsafe. Unfast.

A few things work, though, like ummm... loading and deserializing the binary chunks. On 64-bit little-endian architectures at least. And running some trivial programs (see ./vm/testdata). Closures that actually use the closed-over environment currently don't work (upvalues in Lua literature). Tail calls and variadic arguments and return values don't work. Metamethods are not there yet.
