Usage

$ npm i chordproject-parser

Load with import:

import { ChordProParser } from "chordproject-parser";

Parser

To use the ChordProParser:

const parser = new ChordProParser();
const song = parser.parse(chordSheet);

Formatter

You can choose between 3 formatters: TextFormatter, HtmlFormatter and ChordProFormatter.

const formatter = new HtmlFormatter();
const songText = formatter.format(song);

The formatters have default settings. You can change pass the settings in the formatter's constructor or change the settings later. Here is an example:

const settings = new FormatterSettings();
settings.showChords = false;
const formatter = new HtmlFormatter(settings);

or simply

const formatter = new HtmlFormatter(settings);
formatter.settings.showChords = false;

    {title: Praise Adonai}
    {artist: Paul Baloche}

    B|---3---3---3---|-----0-------
    G|-2-------------|---0---------
    D|---------------|---0---------
    A|---------------|-2-----------
    E|---------------|-------------
    {eot}

    [Am]Who is like [F]Him,
    The Lion and the [C]Lamb
    Seated on the [G]throne    [E7]
    [Am]Mountains bow [F]down
    Every ocean [C]roars
    To the Lord of [G]hosts

    {start_of_chorus}
    [F]Praise Ado[Am]nai
    From the [G]rising of the sun
    'Till the [Dm7]end of every [F]day[G]
    [F]Praise Ado[Am]nai
    All the [G]nations of the earth
