mathlive - npm Package Versions

0.96.1 2023-11-15

Improvements

• Simplified the syntax to modify registers. Use mf.registers.arraystretch = 1.5 instead of mf.registers = {...mf.registers, arraystretch: 1.5}`
• Allow changing registers using \renewcommand, for example \renewcommand{\arraystretch}{1.5}
• Added keycap shortcuts [up] and [down] to move the selection up or down in a matrix.
• Display the environment popover when the selection is inside a matrix, even when the virtual keyboard is not visible.

Issues Resolved

• #2159 Runtime error in sandboxed mode when in an iframe from different origin
• #2175 Addressed some rendering issues with Safar where a fraction inside a \left...\right was vertically offset.
• #2176 Using the [hide-keyboard] virtual keycap would cause a runtime error.
• #2161 When the virtual keyboard is hidden, a geometrychange event is dispatched.

0.96.0 2023-11-14

Breaking Changes

• The function serializeMathJsonToLatex() has been renamed to convertMathJsonToLatex() for consistency.

Issues Resolved

• A closing parenthesis following a function application would be ignored, i.e. (f(x)) would be parsed as (f(x).
• #2116 Pressing the "/" key after an expression ending with a superscript would not recognize the left argument as a numerator.
• #2124 In text mode, some characters were incorrectly interpreted as a math command, for example ( was interpreted as \lparen`. This could cause some interoperability issues.
• #2110 If using the keyboard to enter several macros mapping to an \operatorname command, some of the commands could fail to render. For example, typing "1mm + 2mm" in a mathfield would result in "1 + 2mm" to be displayed.
• When inserting an mchem atom, preserve the verbatimLatex associated with the atom, so that the value property of the atom is correctly serialized.
• When invoking the moveToMathfieldEnd command, the selection was not changed if it was not collapsed and already at the end of the mathfield. Similarly for moveToMathfieldStart.

Improvements

• Added support for additional commands from the mathtools, actuarialangle, colonequals, statmath and amsopn packages
• Added support for longdiv enclosure (\mathenclose{longdiv}{...})
• The decimal separator key (.) in the virtual keyboard was displayed as a blank key.
• #2109 In the virtual keyboard, some placeholders could be hard to see when a keycap was in a pressed state.
• #2105 The keycap shift + in the numeric keyboard was inserting a sum with limits contrary to what the keycap label indicated.
• In the alphabetic virtual keyboard, the , key now produces a semicolon when shifted and has a variant panel with additional punctuation.
• Improved virtual keyboard for integrals with more explicit template
• When removing the limit of an integral or a sum, do not delete the operator itself.
• #2122 On the Virtual Keyboard, the multiplication key now produces \cdot instead of \times. Use shift to produce \times.
• Improved serialization to ASCIIMath and MathML (#2130 and others)
• #2121 For ASCIIMath and MathML serialization, including phantom closing delimiter in the output.
• Pressing the Action keycap on the virtual keyboard with the shift key pressed now inserts a new line (similar to what shift+enter does on a physical keyboard).
• Render \displaystyle and \textstyle to MathML
• Avoid runtime error if the mathfield gets deleted during a selection change event.

0.95.5 2023-08-18

Issues Resolved

• #2091 The variant panel for the 7 key was the variant panel for 4.
• #2093 Inline shortcuts can be corrected with backspace, i.e. typing sen[backspace][backspace]in will be corrected to \\sin.
• #2018 Some VK toolbar items could be offset by a few pixels on some mobile devices
• The caret was not visible when placed after an \operator*{} command
• The \class{}{} command in a mathfield was not working correctly.

Improvements

• #2052 When double-clicking then dragging, the selection is now extended to the nearest boundary. This applies to math, text and LaTeX zones.
• Added prompt CSS part to the mathfield element. This allows styling of prompts (placeholders) in a fill-in-the-blank mathfield.
• Added w40 keycap class (4-wide)
• When using renderMathInElement() preserve the LaTeX as a data- attribute on the element.
• Added speakable text for \imaginaryI, \imaginaryJ, \ne and \neq
• Added ARIA label to keyboard toggle glyph
• More robust check for PointerEvent support
• Throw an error if attempting to access mf.mathVirtualKeyboard. The virtual keyboard is now a singleton, accessible as window.mathVirtualKeyboard.
• When a command attribute is associated with a keycap, a math-virtual-keyboard-command event is dispatched when the keycap is pressed.

0.95.4 2023-08-11

Issues Resolved

• #2090 A runtime error could occur when adding a superscript inside a square root
• #2068 Use a more compact keyboard layout for phones in landscape mode.

Improvements

• #2089 Added x^{#?} in the virtual keyboard variant panel for x
• #2082 The shortcut for \int was triggered with sint. Note that in case of similar conflicts, pressing the spacebar will prevent the shorcuts from taking effect, i.e. "sin t".

0.95.2 2023-08-09

Improvements

• Added if-math-mode and if-text-mode classes to conditionally show virtual keyboard keys.
• #2086 When navigation a root with an index, the index is now navigated first.

0.95.1 2023-07-25

Improvements

• #2064, #2065 Improved behavior of virtual keyboard shift key, contributed by https://github.com/oscarhermoso

Issues Resolved

• #1995 When right clicking to bring up the variant panel in the virtual keyboard, in some situations the virtual keyboard would lock up.
• #2047 Use \exp instead of \mathrm{exp} in the virtual keyboard
• #2067 When setting up the virtual keyboard policy to "sandboxed" in a cross domain iframe, a runtime error would occur.

0.95.0 2023-07-04

Improvements

• Improved behavior when pressing the tab key
• #2015 New environmentPopoverPolicy option. Set to:
  • "auto" to show environment popover when inside a tabular environment and the virtual keyboard is visible (current behavior)
  • "on" to show it when in a tabular environment
  • "off" to never show it

Issues Resolved

• #2008 The \underline and \overline commands now render correctly.
• #1996, #2025 MathML output could occasionally be incorrect for the
  \left...\right command
• #2009 Chemical equations did not render correctly
• #1990 The closing delimiter of a \left...\right command was incorrectly adopting the style of the last atom inside the command.
• #2044 When overflowing the mathfield using the virtual keyboard, the caret would be hidden from view.
• #2000, #2016 Correctly handle when the root is not a group, i.e. when it's a multi-line array.

0.94.8 2023-06-15

Improvements

• On RTL system, do not flip the direction of the virtual keyboard keycaps rows

0.94.7 2023-06-08

Improvements

• #1989 Temporarily add back support for iOS versions older than 16.3.
