Changelog
0.98.5 2023-12-27
When a font size command is inside a \left...\right command, apply the font
size to the content of the command. As a result
\frac34 + \left( \scriptstyle \frac12 \right) will now render as expected.
#2214 When using Linux or Windows with a German keyboard layout, typing
the ^ key will now switch to superscript.
#2214 When typing Unicode characters such as ² or ℂ, correctly
interpret them as their LaTeX equivalent. This also affects parsing of the
value property.
#2000, #2063 A mathfield with multiple lines now generate correct
LaTeX using the \displaylines command.
When a superscript or subscript is attached to a function, correctly position
a following \left...\right command closer to the function.
When typing a superscript after f, g or some other function, correctly
interpret the superscript as an exponent, not as a function argument.
#787, #1869 The f, g and h symbols are no longer hardcoded as
symbols representing functions.
Whether a symbol is considered a function affects the layout of a formula, specifically the amount of space between the symbol and a subsequent delimiter such as a parenthesis.
Now whether a symbol should be treated as a function is determined by the
MathfieldElement.isFunction hook.
By the default, this hook uses the MathfieldElement.computeEngine to
determine if the domain of a symbol is a function.
This can be customized by setting the isFunction property of the mathfield
or by declaring a symbol as a function using the declare() method of the
compute engine. For example:
MathfieldElement.computeEngine.declare("f", "Functions");
In addition, a new isImplicitFunction hook has been added which can be used
to indicate which symbols or commands are expected to be followed by an
implicit argument. For example, the \sin function can be followed by an
implicit argument without parentheses, as in \sin \frac{\pi}{2}. This
affects the editing behavior when typing a / after the function. If an
implicit function, the / will be interpreted as an argument to the function,
otherwise it will be interpreted as a fraction with the function as the
numerator.
The "phi" keycap in the virtual keyboard was incorrectly displaying the
\varphi symbol. It now displays the \phi symbol.
#2227 Updating the content of the mathfield with mf.innerText will now
correctly update the value of the mathfield.
#2225 For consistency with <textarea>, when setting the value change the
selection to be at the end of the mathfield.

Using MathLive is easy! Simply add a <math-field> tag to your page. It
initializes automatically and works just like a <textarea> or <button>
element. You can manipulate the mathfield using methods of the element and
listen for events to be notified when its internal state changes.
npm install mathlive
import 'mathlive';
<!DOCTYPE html>
<html lang="en-US">
<body>
<math-field>f(x)=</math-field>
</body>

Check documentation for React and interaction with Mathfield.
MathLive has an extensive set of documentation to help you get started, including guides on interacting with a mathfield, customizing it, executing commands, defining custom LaTeX macros, managing inline and keyboard shortcuts, controlling speech output, and displaying static math formulas. You can find all of these guides on the CortexJS.io website.
In addition to the guides, you can also find reference documentation of the MathLive API on the MathLive SDK page.
