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)
|
|
}
|
