Pony Considerations

If you're thinking of checking out the Pony programming language, here's a list of things that I think are important to know. This list is based on a Tweet that I wrote.

Editor/IDE support

There are Pony packages for several popular editors.

• Emacs
• Sublime

var ringGain = wac.createGainNode();
ringGain.gain.setValueAtTime(0, 0);

var ringCarrier = wac.createOscillator();
ringCarrier.type = ringCarrier.SINE;
ringCarrier.frequency.setValueAtTime(2500, 0);

Recently I've been trying to modify the way that I use the word "just" when I'm at work. Merriam Webster offers a few definitions of the word; the one I'm interested in is the one that means "only", "simply", and to a lesser extent "exactly". I've been working on a new project that involves integrating a number of systems, and as I began rolling pieces out I received a lot a questions in the form of "Couldn't you just ...?" These annoyed me at first, but as I thought about it I realized I often asked questions in the same way, so I began to examine the word and the way I use it.

    let lit = [(lambda(s:String): String ref => String().append(s) end, lambda(s:String): String ref => String().append(s) end),
               (lambda(s:String): String ref => String().append(s).append(s) end, lambda(s:String): String ref => String().append(s).append(s) end),
               (lambda(s:String): String ref => String().append(s).append(s).append(s) end, lambda(s:String): String ref => String().append(s).append(s).append(s) end)]

    var result = String()
    for (la, lb) in lit.values() do
      result = result.append(la("a")).append(lb("b"))
    end
