mathlive - v0.26

Published by arnog over 5 years ago

Breaking Changes

Public method now start with $. This convention is also used, for example,
by the Vue.js project. For now, aliases exist that begin with '_' (the previous
convention), however you are encourage to migrate as soon as possible. The
function that are affected are: _el(), _insert(), _keystroke(), _latex(),
_perform(), _revertToOriginalContent(), _selectedText(),
_selectionAtEnd(), _selectionAtStart(), _selectionDepth(),
_selectionIsCollapsed(), _setConfig(), _text(), _typedText() (this was initially implemented in 0.25)

Major New Features

Support for dark mode. Triggered automatically by the browser or
by setting theme="dark" on the <body> tag.
New implementation for inline shortcuts. Now support complex inline
shortcuts including _, ( and other keys.
Virtual Keyboards can now be described using a JSON data structure. Contribution from @rpdiss. Thanks!
New MathLive.toSpeakableText() function
New config.onAnnounce handler

Other Improvements

The $perform() function now accepts selector both in camelCase
or kebab-case.
Improved display of some keys in the keyboard caption panel
New logo!
Improved documentation, including adding pages for keyboard shortcuts,
examples, macros, selectors and config options.
Better support for IE11 via transpiling (thanks @synergycodes!)

Bug fixes

#103 - Fixed issues where the math path could become invalid. Also made the
code more resilient to invalid paths.
#128 - Properly cleanup event handlers on destruction

Codebase Health and Performance

Some minor optimizations and performance improvements, including
lazy loading of sounds and some other resources.
Moved some modules to classes.

mathlive - Vue support

Published by arnog almost 6 years ago

Added support for a Vue wrapper.

mathlive - 0.24.1 (December 17, 2018)

Published by arnog almost 6 years ago

Fix issues in keyboard handling.

mathlive - 0.24 (December 16, 2018)

Published by arnog almost 6 years ago

Breaking Changes

Several handlers had some inconsistent signatures, or in some cases passed
invalid values as their arguments. This has been fixed, but it
required changing the signature of some handlers. For consistency, the first
argument of the handlers now refers to the mathfield to which it applies.

    MathLive.makeMathField('input', {
        onContentDidChange: mf => {
            document.getElementById('output').innerHTML = mf.latex();
        }
    });

Keep in mind that arrow functions lexically bind their context, so this
actually refers to the originating context (not to the mathfield).

The affected handlers are:

onFocus
onBlur
onKeystroke
onMoveOutOf
onTabOutOf
onContentWillChange
onContentDidChange
onSelectionWillChange
onSelectionDidChange
onUndoStateWillChange
onUndoStateDidChange
onVirtualKeyboardToggle
onReadAloudStatus

It is recommended that you check if you use any of those handlers and
validate their signatures.

Major New Features

Support for native JavaScript modules, contributed by
Jason Boxman (https://github.com/jboxman). Thanks, Jason!

The previous method, using a <script> tag, is still supported:

    <script src="../../dist/mathlive.js"></script>

but it is recommended to use native JavaScript modules:

    <script type='module'> 
        import MathLive from '../../dist/mathlive.mjs';
    </script>

(note the .mjs extension indicating this is a JavaScript module).

A few caveats about using modules:

JavaScript modules are automatically in strict mode
To use JavaScript modules you need to be in your own module. With a <script>
tag, this is indicated by adding the type='module' attribute. The code inside
a module is not leaked to the global scope, the module has its own scope. As a
result, functions defined inside the module (inside your <script> tag) will
not be visible outside the module. You will need to either attach them to a
global object (such as window) or in the case of even handlers, attach them
to the relevant element, using addEventListener.

See examples/basic/index.esm.html for a complete example.

If you were previously loading the non-minified version, that is the raw sources,
which can be useful to debug issues, you need to use modules to load them, while
you may have used requirejs previously. The sources are now included in the
distribution for this purpose.

Instead of:

    define(['mathlive/src/mathlive'], function(MathLive) {
        MathLive.makeMathField(/*...*/);
    }

use:

    import MathLive from '../../dist/src/mathlive.js';
    MathLive.makeMathField(/*...*/);

Support for SRE (Speech Rule Engine) from Volker Sorge. Optional, and needs
to be installed separately.
Improved text to speech support, including karaoke mode (read aloud with
synchronized highlighting)
New configuration setting to control the spacing between elements,
horizontalSpacingScale. Supplying a value > 1.0 can improve readability for
some users.
Added notifications when undo state change, onUndoStateWillChange and
onUndoStateDidChange
Added support for correctly inserting rows and columns in arrays.

Other Improvements

Fixes in MASTON
Improved cross-browser accessibility support
Fix MathML output for superscripts
Fix issue #75 (autoconvert would fail in some cases)
Fix issue #114. Incorrect selection when shift-select at the end.
Fix issue #78. Cross-out positioning issue

mathlive - v0.0.15

Published by arnog over 7 years ago

0.0.15 (July 1, 2017)

New Features

Properly exported public API, including renderMathInDocument() and
renderMathInElement()
Added \enclose command, implementing the MathML equivalent.
Added \cancel, \bcancel and \xcancel commands
Added preserveOriginalContent option to MathLive.renderMathIn...()
Made \backslash work in text mode, for example when an argument of \rlap{}
Added MathField.revertToOriginalContent() when a math field is no longer
needed for an element
Added customization of the command bar. See MathField.config() and
config.commands
Added MathLive.revertToOriginalContent() and MathLive.getOriginalContent()
Added optional namespacing of data- attributes
Added onContentWillChange and onContentDidChange handlers in the math
field config object.
Added tutorials and improved documentation

Bug Fixes

Fixed #5: AZERTY keyboard input was misbehaving, particularly for the ^ key
Dead keys (´, ^, ¨, ˜ and others on some keyboards) were not properly
handled
Complex emojis (emojis made of multiple codepoints, such as emojis with skin
tone modifiers, or emojis with a ZERO WIDTH JOINER, such as the David Bowie
emoji) would be incorrectly recognized as multiple symbols
Fixed the \color command
Properly roundtrip to LaTeX \rlap, \color and many other commands. Now,
copying content using these commands in a math field will result in the correct
LaTeX code to be generated.
