Reactive Extensions for D Programming Language

Build Status

Overview

The is a library like the Rx.NET, for the asynchronous or event-based programs on OutputRange concept.

Basic concept interfaces
//module rx.disposable
interface Disposable
{
    void dispose();
}

//module rx.observer
interface Observer(E) : OutputRange!E
{
    //void put(E obj); //inherits from OutputRange!E
    void completed();
    void failure(Exception e);
}

//module rx.observable
interface Observable(E)
{
    alias ElementType = E;
    Disposable subscribe(Observer!E observer);
}

Example
import rx;
import std.algorithm : equal;
import std.array : appender;
import std.conv : to;

void main()
{
    auto subject = new SubjectObject!int;
    auto pub = subject
        .filter!(n => n % 2 == 0)
        .map!(o => to!string(o));

    auto buf = appender!(string[]);
    auto disposable = pub.subscribe(buf);

    foreach (i; 0 .. 10)
    {
        subject.put(i); //fire some event
    }

    auto result = buf.data;
    assert(equal(result, ["0", "2", "4", "6", "8"])); //receive some event
}
