2024-08-05 09:15: Want to see how hard this is to do #itparser-rust

I think I know enough Rust where the "it's in Rust" part isn't all that challenging anymore. There is one definitive spec file for IT.

2024-08-05 09:48: browsing IT files #itparser-rust

2024-08-05 10:25: Found an interesting IT file. adding. #itparser-rust

2024-08-05 10:29: Baby's first IT file. #itparser-rust

Just some sine pulses.

2024-08-05 11:04: Okay. that was kinda fun. #itparser-rust

2024-08-05 14:52: Attempts at an IT parser #itparser-rust #timelog:00:12:08

Didn't get far at all.

2024-08-05 19:37: Another attempt? Another attempt. #itparser-rust #timelog:00:27:02

2024-08-06 16:04: More stabs at the parser #itparser-rust #timelog:00:50:13

Got far enough to do some initial parsing of pattern data. Good enough for me for now.

2024-08-08 09:30: What's a good stopping point for this #itparser-rust

I think it would be nice to work this out in such a way that it exports JSON data for the patterns. Probably just low-level row information for now (Serde?). Later that can data can be analyzed by other programs to do things like extract notes and durations and so on.

It's a good proof of concept for a proof of concept. I can return to it later, if I need it.
