OCaml-Python Bindings Generator
Generate Python bindings with pyml directly from OCaml value specifications.
While you could write all your Python bindings by hand, it can be tedious and it gets old real quick. While pyml_bindgen
can't yet auto-generate all the bindings you may need, it can definitely take care of a lot of the tedious and repetitive work you need to do when writing bindings for a big Python library!! 💖
Quick start
First, install pyml_bindgen
. It is available on Opam.
$ opam install pyml_bindgen
Say you have a Python class you want to bind and use in OCaml. (Filename: adder.py
)
class Adder:
@staticmethod
def add(x, y):
return x + y
To do so, you write OCaml value specifications for the class and methods you want to bind. (Filename: val_specs.txt
)
val add : x:int -> y:int -> unit -> int
Then, you run pyml_bindgen
.
$ pyml_bindgen val_specs.txt adder Adder --caml-module Adder > lib.ml
Now you can use your generated functions in your OCaml code. (Filename: run.ml
)
open Lib
let () = Py.initialize ()
let result = Adder.add ~x:1 ~y:2 ()
let () = assert (result = 3)
Finally, set up a dune file and run it.
(executable
(name run)
(libraries pyml))
$ dune exec ./run.exe
