# Lua in Odin
Lua packages
* `vendor:lua/5.1` (version 5.1.5)
* `vendor:lua/5.2` (version 5.2.4)
* `vendor:lua/5.3` (version 5.3.6)
* `vendor:lua/5.4` (version 5.4.2)
With custom context-based allocator:
```odin
package lua_example_with_context
import "core:fmt"
import lua "vendor:lua/5.4" // or whatever version you want
import "core:c"
import "base:runtime"
state: ^lua.State
lua_allocator :: proc "c" (ud: rawptr, ptr: rawptr, osize, nsize: c.size_t) -> (buf: rawptr) {
old_size := int(osize)
new_size := int(nsize)
context = (^runtime.Context)(ud)^
if ptr == nil {
data, err := runtime.mem_alloc(new_size)
return raw_data(data) if err == .None else nil
} else {
if nsize > 0 {
data, err := runtime.mem_resize(ptr, old_size, new_size)
return raw_data(data) if err == .None else nil
} else {
runtime.mem_free(ptr)
return
}
}
}
main :: proc() {
_context := context
state = lua.newstate(lua_allocator, &_context)
defer lua.close(state)
lua.L_dostring(state, "return 'somestring'")
str := lua.tostring(state, -1)
fmt.println(str)
}
```
