@chordlang/parser

Peggy parser for chordlang chart structure (.cfmd lead sheets).

Parses bar grids, section markers, and metadata directives. Chord tokens are opaque strings — symbol normalization lives in @chordlang/chord.

The grammar file src/chart.peggy is the format spec.

Install

npm install @chordlang/parser

Usage

import { parseChart } from "@chordlang/parser";

const ast = parseChart(`
{title: F Blues}
| F7 | Bb7 | F7 |
`);

// ast.directives, ast.body — bars, sections, barline-end nodes
