rust-abc-2

ABC Parser written in rust using PEG.

Usage

Add the package to your cargo dependencies.

[dependencies]
abc-parser = "0.2"

Then you can use the PEG generated rules through the abc module.

extern crate abc_parser;

use abc_parser::datatypes::*;
use abc_parser::abc;

let parsed = abc::tune_book("X:1\nT:Example\nK:D\n").unwrap();
assert_eq!(
    parsed,
    TuneBook::new(None, vec![
        Tune::new(
            TuneHeader::new(vec![
                InfoField::new('X', "1".to_string()),
                InfoField::new('T', "Example".to_string()),
                InfoField::new('K', "D".to_string())
            ]),
            None
        )
    ])
)

There is a good chance that the dev branch may have more recently added features which arent complete but won't (probably) break the existing functionality. You can also tell cargo to install directly from the dev branch like this:

[dependencies]
abc-parser = { git = "https://gitlab.com/Askaholic/rust-abc-2", branch = "dev" }

History

The first version was an attempt to write the parser by hand, but using PEG is much more maintainable. The older repo is here: https://gitlab.com/Askaholic/rust-abc
