/**
|
||
|
|
Loads and returns a plugin from file `filePath`.
|
||
|
|
|
||
|
|
If Haxe is built natively, the extension automatically defaults to `.cmxs`,
|
||
|
|
even if a different extension is provided in `filePath`. In bytecode mode,
|
||
|
|
the default extension is `.cmo`.
|
||
|
|
|
||
|
|
Sample plugin:
|
||
|
|
|
||
|
|
```ocaml
|
||
|
|
open EvalValue
|
||
|
|
open EvalContext
|
||
|
|
open EvalEncode
|
||
|
|
|
||
|
|
let add_int = vfun2 (fun v1 v2 -> match v1,v2 with
|
||
|
|
| VInt32 i1,VInt32 i2 -> vint32 (Int32.add i1 i2)
|
||
|
|
| _ -> exc_string "Expected int + int"
|
||
|
|
)
|
||
|
|
;;
|
||
|
|
EvalStdLib.StdContext.register ["add_int",add_int]
|
||
|
|
```
|
||
|
|
|
||
|
|
Usage from Haxe:
|
||
|
|
|
||
|
|
```haxe
|
||
|
|
var module:TestPlugin = eval.vm.Context.loadPlugin("testPlugin.cmo");
|
||
|
|
trace(module.add_int(4, 3));
|
||
|
|
```
|
||
|
|
|
||
|
|
Plugins have to be compiled with the same OCaml version as the Haxe compiler
|
||
|
|
and using the same Haxe version. If a plugin cannot be loaded, an exception
|
||
|
|
of type `String` is thrown.
