mathlive - npm Package Versions

0.93.0 2023-05-08

New Features

• Support for \the command. For example, \the\year. Its argument can be a literal or a register, preceded by an optional factor literal.
• In addition to the label property, the key property can also now be used for keycap shortcuts. This allow overriding of the shortcut label. For example {key: "[undo]", label: "undo"}
• Added support for --keyboard-row-padding-left and --keyboard-row-padding-right as an option to account for shadows or other decoration that may spill outside the box of a keycap.
• Fixed opacity of Undo button in virtual keyboard, when the button is not applicable.
• The minFontScale property has been added that specifies the minimum font size that should be used for nested superscripts and fractions. The value should be between 0 and 1. The size is in releative em units relative to the font size of the math-field. The default value is 0, which allows the math-field to use its default sizing logic.
• If no mathfield is focused the virtual keyboard will dispatch a keydown/keyup event pair. Add an event listener to the keyboard to receive those events.

Improvements

• Improved performance of creation and destruction of mathfields by 50%.
• Fixed memory and listener leaks. After creating, inserting in the DOM, then removing over 100,000, the memory is back to its starting point and there are no listeners left (except for those associated with the Virtual Keyboard).
• Improved behavior of undo/redo. #1924 works in LaTeX mode. Undo shortcut substitution. Repeated operations (e.g. backspace) are considered a sinle operation for undo/redo purposes.
• Importing the Compute Engine and MathLive in the same projec should no longer trigger a conflict.

Issues Resolved

• #1646 mhchem: states of aggregation is now rendered correctly. Added support for the \mskip command
• When editing a mathfield, after inserting both a superscript and subscript, the subscript would be offset from the superscript.
• #1668 Correctly handle \space, ~
• #1939 When the parent of the Mathfield is scaled, apply the scaling to the selection rectangles
• Fixed parsing of emojis such as 🧑🏻‍🚀
• The focus outline is no longer displayed when in readonly mode
• #1940 New attempt to preserve the focus of mathfields when a window loses, then regains focus (when switching tabs, for example).
• At certain sizes, the \left...\right command did not display the visual indicator that the caret was inside the argument of the command.
