Luar is designed to make using Lua from Go more convenient. Go structs, slices and maps can be automatically converted to Lua tables and vice-versa. The resulting conversion can either be a copy or a proxy. In the latter case, any change made to the result will reflect on the source.
Any Go function can be made available to Lua scripts, without having to write C-style wrappers.
Luar support cyclic structures (map[string]interface{}, lists, etc.).
User-defined types can be made available to Lua as well: their exported methods can be called and usual operations such as indexing or arithmetic can be performed.
See the documentation for usage instructions and examples.
Install with
go get <repo>/luar
Luar uses Alessandro Arzilli's golua. See golua's homepage for further installation details.
An example REPL is available in the cmd folder.
The GoToLua and LuaToGo functions take a reflect.Type parameter, which is
bad design. Sadly changing this would break backward compatibility.
