Subject: [Caml-list] [ANN][PATCH+PPX] Curried constructor
Date: Fri, 4 Sep 2015 15:58:52 -0700 [thread overview]
Message-ID: <CAAoLEWsO+vbi3Y6QkmmAwhw-4bR3bDvmjDt-LNi7_0kT3mzkNA@mail.gmail.com> (raw)
Hi,
I wrote curried-constr patch for OCaml 4.02.3. It makes variant
constructors usable like functions.
For the type definition
type t = Foo of int * float
we can write
Foo as (fun (x,y) -> Foo (x,y))
ad
!Foo as (fun x y -> Foo (x,y))
There are two ways to try this extension: as a compiler modification,
and as a PPX preprocessor:
* opam switch 4.02.3+curried-constr (as a patched compiler)
* opam install ppx_curried_constr (as a PPX preprocessor)
Enjoy!
