MathQuill 4 Quill
What's this?
This module adds support for rich math authoring to the Quill editor.
Usage example
Plain Javascript
This module depends on MathQuill, Quill and KaTeX, so you'll need to add references to their JS and CSS files in addition to adding a reference to mathquill4quill.js
and mathquill4quill.css
. Official builds as well as minified assets can be found on the releases page.
Next, initialize your Quill object and load the formula module:
// setup quill with formula support
var quill = new Quill('#editor', {
modules: {
formula: true,
toolbar: [['formula']]
},
theme: 'snow'
});
Last step: replace Quill's native formula authoring with MathQuill.
// enable mathquill formula editor
var enableMathQuillFormulaAuthoring = mathquill4quill();
enableMathQuillFormulaAuthoring(quill);
A working demo application can be found here (live).
React
A demo application integrating this module with react-quill can be found here (live). A demo for NextJS can be found here.
Optional features
Custom operator buttons
You can also add in operator buttons (buttons that allow users not familiar with latex to add in operators/functions like square roots) to the editor by passing the operators
option to the enableMathQuillFormulaAuthoring()
function. Example:
enableMathQuillFormulaAuthoring(quill, {
operators: [["\\sqrt[n]{x}", "\\nthroot"], ["\\frac{x}{y}","\\frac"]]
});
The operators variable is an array of arrays. The outside array contains all of the different arrays which describe the operator buttons. The arrays inside of the main array consist of two values. The first value is the latex that gets rendered as the value on the button, and the second value is the latex that gets inserted into the MathQuill editor.
List of previous formulas
Previous formulas can be saved and re-used. The available related configurations are:
enableMathQuillFormulaAuthoring(quill, {
displayHistory: true, // defaults to false
historyCacheKey: '__my_app_math_history_cachekey_', // optional
historySize: 20 // optional (defaults to 10)
});
This works by saving formula to a list (and local storage by default) everytime a new formula is used. Then displaying this list when a user opens the formula tooltip.
Autofocus
For user convenience, mathquill4quill defaults to focusing the math input field when the formula button is pressed. You can disable this behavior via the autofocus
option in the enableMathQuillFormulaAuthoring()
function. Example:
enableMathQuillFormulaAuthoring(quill, {
autofocus: false
});
Development setup
First, install the development dependencies:
npm install
You can now start the development server using npm start
, verify code style compliance with npm run lint
and run the tests with npm test
.
