Last night I reimplemented MIDI support in LilyPad. It turned out to be really easy to use the AudioToolbox framework’s MusicSequence and MusicPlayer classesopaque C data types + functions. One bug to be fixed: if a new preview happens while you’re playing, the old sequence continues to play. This can be comical, but not useful.

I made a few fixes in LilyPad today to take care of two bugs:

• ID 9, Auto-preview behavior is a little annoying
• ID 8, Keyboard shortcuts for indentation aren’t internationally friendly

ID 9

Regarding auto-preview, Henning Ramm had written:

It’s really a nice feature, but doesn’t yet behave “just right”. I’d like to start it with every “save” (or after the delay) and then run through (but stoppable), regardless what I type in the meantime. For it’s not possible to just preview the part I work at, that would show my progress better than if I must stop typing to see anything. Perhaps you can make that behaviour configurable, too.

Done. I didn’t bother to make it configurable—if somebody complains about the default behavior, I can do that.

ID 8

Also a request from Henning:

- increase/decrease indent of marked lines using tab/shift-tab (the actual keys don’t work on every int’l keyboard)

Also done. I was previously of the opinion that doing this would violate standard OS X behavior. But this is how Eclipse does it, and I like it. So I’m going with it.

I finished setting up the Mantis bug-tracker and brought in bugs from my old Bugzilla.

First completed off the to-do list:

• Some strings are not localizable
• Previewing causes LilyPond 2.8 to open file in Preview
• Cannot open or save

You can now browse the repositories for the two available projects (EcoGillespie and LilyPad) using WebSVN:

• EcoGillespie
• LilyPad

I did a little cleanup on the source code for LilyPad and put it into a public Subversion repository. The code is available for (really rudimentary) online viewing here.

I still haven’t implemented most of the things I was going to have implemented by now–other things (e.g., the Summer of Code proposal) have taken over, as they always seem to do. But there are a few changes since the last preview version:

• It’s building as a Universal Binary—full speed ahead on Intel Macs. This actually makes some sense now that LilyPond itself is Intel-native.
• Rudimentary proof-of-concept parenthesis matching. Doesn’t actually match LilyPond syntax quite right yet, but it’s a start.
• The elimination of any way to play MIDI. With the intention, of course, of rewriting it in CoreMIDI…but that hasn’t happened yet. So I’ve actually removed a feature.
• Now handling textedit:// URLs as LilyPond.app does. When you run LilyPad, it makes itself the default handler for those URLs.

One known bug off the top of my head: I’m using the python LilyPond script embedded in LilyPond.app, which likes to open up the file in Preview after it’s done being generated. This is beyond annoying.
