OnSong parser

[bkeepers]

The OnSong format is loosely based on ChordPro, and after looking at it more closely over the last few days, I really like it. It's more human-readable (no more { and }) and has a number of improvements, especially with regard to how chordsheets are typically structured (metadata, sections, and Flow).

I'm looking for a preferred format for https://github.com/bkeepers/chordbook (chordbook/chordbook#130) and would like to try OnSong.

Would you be open to accepting a Pull Request for an pegjs-based parser for OnSong?

Hey @bkeepers. Yeah, that would be a great addition! Would that also include the formatting part?

[bkeepers]

Awesome, I'll get a PR open soon. I'm about 50% done with the grammar.

We'll have a lot to talk about. OnSong is basically a superset of both ChordPro and ChordSheet formats. The AST will need to be structured differently than ChordPro to get the Flow metatag to work. It might still be able to be deserialized into the same Song model, but there may need to be some modifications.

Hey @martijnversluis do you know if this PR has been completed?

[bkeepers]

@mfuentesg Not yet, but for now I extracted this to its own package: https://github.com/chordbook/onsong

I'd love to see OnSong support get added to ChordSheetJS eventually, but it's not a priority for me right now.
