Live Coding in CoffeeScript (opens in new tab)

Sean, I wish you'd take a closer look at live coding before saying this kind of thing, you've very much got the wrong idea about live coding. I'm just off to work but I'll send you some references later.

Live coding is absolutely everything about live feedback. This gives you access to performing in front of a live audience, but that is only part of it. It also allows new styles of collaborative programming, and exploring of ideas in composition.

Live coding is about using programming languages to manipulate running code, maintaining state (if there is any).

Check out the code in the "hacking perl in nightclubs" article that this one links to. The software it discusses takes on live updates without restarts or losing state (in fact, the code in the editor is part of the state). It also has an option to take on edits every keypress, but it's off by default, because it's impractical. Sometimes you just don't want 1 and 10 to be interpreted on the way to 100.

Live coding arose in an interdisciplinary context of music performance, pedagogy, media theory, psychology and computer science.

The thesis you link to is really excellent, but has shared roots with live coding and is referenced in the live coding literature.

Ah, I see now. It's not related to "live programming," but rather the live performance as you said. It's the first time I hear of it in that context, but I understand now. Thanks!

Both meanings are equally repulsive and are activities without merit. The fact that this is about coffeescript doesn't surprise me at all.

"and just starting to learn CoffeeScript, because it seemed rather cool"

This thought pattern is wholly flawed. "Seems cool" is not a reason to learn coffeescript, in fact there is no good reason except syntax fetishism, which is also not a good reason.

Ah, I should have been clearer. MIDI to sheet music conversion is trivial. What I want to do is take real audio as input and convert that, which is according to my readings really hard because MIDI and audio formats (FLAC/WAV/MP3 etc) are very different.

There are some tools that I could find but so far none has come up with good conversion from FLAC or MP3.

I'm mainly interested in classical music and that kind of complicates things. As the number of voices in your audio increase, it gets that much harder to export it to MIDI. I've been thinking about emphasising the melody line and exporting that to MIDI but so far nothing :P

Perhaps a different approach would work better.

But thanks a lot for the help :)
