MathJax-src

This is the first public beta release of MathJax v3.

NOTE

This is an early beta release. Do not use this in production but please test it and report issues at https://github.com/mathjax/mathjax-v3/issues!

The master branch is not the beta release; it is the current development copy, set up for development testing. The beta branch is the beta release.

What's Included

This beta version includes two input processors (TeX and MathML) and one output processor (CommonHTML). Other input and output processors (e.g., AsciiMath input and SVG output) will be added in the future.

The current TeX input processor has all the core functionality of the MathJax v2 TeX input, and several of the extensions built in, but some extensions are still to come. For example, \unicode, \bbox, and the color extension are not yet available.

The CommonHTML output implements all the MathML elements that v2 does, but does not yet include support for line breaking (neither automatic nor explicit ones); this will be implemented in a later beta version. Currently, there is no support for characters that are not within the MathJax TeX fonts, but that will be included in the future.

The MathJax contextual menu is not yet implemented.

The ability to configure MathJax through a configuration object, as in v2, is limited at the moment. In version 3, this type of customization is handled through building custom packed versions of MathJax, and that is not yet fully documented.

Examples

The https://github.com/mathjax/mj3-demos repository includes examples and webpacked files for the beta release. See the instructions there for how to use them.

The https://github.com/mathjax/mj3-demos-node repository includes examples for how to use MathJax version 3 with NodeJS.

Please be advised: do not use this in production.

Changes

• Implements the AMS (math and symbols) packages for TeX input
• Implements the noUndefined package for TeX input
• Adds support for the remaining MathML elements in CommonHTML:
  • Fixed problems with \xrightarrow not stretching properly.
  • Support for the mglyph element (though both width and height must be specified explicitly).
  • Support for the menclose element.
  • Support for the maction element.
  • Support for the mmultiscripts element.
  • Support for MathML spacing rules (rather than TeX spacing)
  • Fixed vertical placement of labels in mlabeledtr rows.
  • Support for the align attribute of munderover, munder and mover.
  • Support for the accent and accentunder attributes on mo and on the munderover, under, and mover elements.
  • Support for the skew font values for better placement of accents.
  • Remapping of hyphen to minus in mo and mn elements, as well as some other accent substitutions for improved output.
  • Support for intentalign, indentshift, and related attributes on the math element.
  • Support for matching the font size of the surrounding text.
• Removes jsdom as a dependency (though you can still use the jsdomAdaptor if you install it yourself). The choosAdaptor now chooses between the browser and lite adaptors (rather than browser and jsdom).

No support yet for line breaking or for fonts other than the MathJax TeX fonts. These are the last remaining big issues for the CommonHTML output.

Also, not support for the MathJax menu. Eventually, that most likely will be an optional extension.

This fixes a problem with the npm version of the alpha.4 release, and tags the correct branch.

Please be advised: do not use this in production.
