Macros
MathLive has over 800 Latex commands predefined. Some are primitives but others are macros, that is commands defined with a Latex expression.
You can view the default macros by inspecting the macros property of the
config object:
import MathLive from 'mathlive';
const mf = document.getElementById('mf'), {
});
console.log(mf.getOption('macros'));
<math-field id='mf'>x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}</math-field>
You can add (or remove) macros by using setOptions({macros: ...}).
import MathLive from 'mathlive';
const mf = document.getElementById('mf');
mf.setOptions({
macros: {
...mf.getOptions('macros'),
smallfrac: '{}^{#1}\\!\\!/\\!{}_{#2}',
},
});
<math-field id="mf">\scriptCapitalE=\smallfrac{5}{7}+\frac{5}{7}</math-field>
The macro definition can contain up to eight arguments, represented by #1 to #9.
