akh.cont

Akh continuation monad

API

The continuation transformer ContT layers continuation control over a monad. The base type Cont, provides continuation control on its own. The continuation transformer is a monad, functor, and applicative functor.

require('akh.cont').Cont

Continuation monad.

Cont.runCont(m, k) m.run(k)

Perform a continuation computation m and complete with outer continuation k.

const Cont = requre('akh.cont').Cont

var c = Cont.of(3)
        .callcc(k =>
            k(4).map(x => x + 1))
        .map((x) => -x);

Cont.run(c, console.log); // logs: -4
c.run(console.log)

Cont.callcc(f)

Reify the current continuation and pass it to f. f can invoke the continuation with a computation to continue execution, or return a computation directly to abort without calling the continuation. f may also capture the continuation k and invoke it multiple times with different values.

require('akh.cont').ContT

The continuation transformer, layers continuation control over a monad. 

ContT.run(m, k) t.run(k)

Same as Cont.runCont but for transformed types

ContT.callcc(m, k)

Same as Cont.callcc but for transformed types
