A parallelism library for Vala and GObject (mirror)

gpseq

Gpseq is a parallelism library for Vala and GObject.

using Gpseq;

void main () {
    string[] array = {"dog", "cat", "pig", "boar", "bear"};
    Seq.of_array<string>(array)
        .parallel()
        .filter(g => g.length == 3)
        .map<string>(g => g.up())
        .foreach(g => print("%s\n", g))
        .wait();
}

// (possibly unordered) output:
// DOG
// CAT
// PIG

using Gpseq;

void main () {
    Channel<string> chan = Channel.bounded<string>(0);
    run( () => chan.send("ping").ok() );
    print("%s\n", chan.recv().value);
}

// output:
// ping

Merge request over on Gitlab

I opened a merge request on the Gitlab mirror of Gpseq, but I can do it over here if that's better.
