exsurge

A JavaScript library for rendering Gregorian Chant in square note notation

Synopsis

exsurge allows developers to create SVG images of square note notation from gabc notation. These SVGs can then be inserted in the DOM or used for presentation purposes.

Live Browser Example

Want to see gabc code rendered to chant on the fly? Try going here.

Code Example

First, create a ChantContext which contains the settings for how the chant will be rendered:

var ctxt = new exsurge.ChantContext();

Then, create a ChantScore from gabc code:

var gabc = "(f3) EC(ce!fg)CE(f) *(,) ad(fe~)vé(f!gwhf)nit(f) (,)"
var score = exsurge.Gabc.loadChantScore(ctxt, gabc, true);

Finally, let the ChantScore handle the layout process, and use the SVG however you want:

// perform layout on the chant
score.performLayout(ctxt, function() {
  score.layoutChantLines(ctxt, 1000, function() {

    // render the score to svg code
    var svgNode = document.createElement('div');
    var innerHtml = score.createDrawable(ctxt);
    svgNode.innerHTML = innerHtml;
    document.body.appendChild(svgNode);
  });
});

Motivation

Very few good chant layout software exist for developers. exsurge allows web developers to insert beautiful chant into their workflow with the simplicity of a little JavaScript.

Developer Installation

After grabbing the repo from github, it's a simple matter of using npm to build exsurge:

npm install
npm run build

Alternatively, you can run npm run dev which will watch and compile the library after saved each change.
