parsehero v0.0.2

parsehero

A small, permissive library used to parse .chart and .midi files made for GuitarHero or CloneHero into usable JSON.

• Permissive - doesn't throw away a whole chart because of a handful of invalid lines
• MIDI - supports the parsing of MIDI files directly from arbirtrary buffer data via midi-file
• Cross-platform - built to work out of the box in the browser and in Node environments
• Built-in timing - parsed charts will their events automatically timestamped by default

Installing

npm install parsehero

[SyncTrack]
{
	0 = B 120000
	0 = TS 4
}
[EasySingle]
{
	0 = N 0 0
}`;

const { chart, warnings } = parseChart(basicChart);
// Use your chart object...
