BuckleScript 1.7.0

October 7, 2017

First class uncurried calling convention

As a functional language, the vanilla OCaml only provides curried calling convention, BuckleScript employs fairly advanced optimizations for curried calling convention, however, the most efficient code is efficient code not relying on optimizations.

Since this release, we provide first class uncurried calling convention, all toolchains provided by BuckleScript can understand uncurried calling convention

.Curried calling convention

.test.ml

let f g x = g x [@bs] // <1>

<1> f is curried function, g is uncurrid function due to [@bs] annotation

bsc.exe -i test.ml # infer the type

val f : ('a -> 'b [@bs]) -> 'a -> 'b // <1>

<1> g is inferred as uncurried function 'a -> 'b [@bs] while f is curried function

.test.js

function f (g,x){ //  <1>
    return g (x)  // <2>
}

<1> f is optimized and flattened <2> g works like uncurried function

API documentation

Now ocamldoc can understand [@bs] natively(instead of printing a desugared output), we provide an API documentation for the library shipped with BuckleScript, we plan to ship the documentation generator in next release.
