CHANGES

3.0.0

Overall there is a major refactoring underway of how formatting works and its interaction with graphics. More work will come in later releases.

Some of the improvements are visible not here but in the front-ends mathicsscript and mathics-django. In mathicsscript, we can now show SVG images (via matplotlib). In Mathics Django, images and threejs graphs are no longer embedded in MathML.

A lot of the improvements in this release were done or made possible with the help of Tiago Cavalcante Trindade.

Enhancements

It is now possible to get back SVG, and graphics that are not embedded in MathML.

The code is now Pyston 2.2 compatible. However scipy lxml are not currently available on Pyston so there is a slight loss of functionality. The code runs about 30% faster under Pyston 2.2. Note that the code also works under PyPy 3.7.

Bugs

  • Tick marks and the placement of numbers on charts have been corrected. PR #1437
  • Asymptote now respects the PointSize setting.
  • In graphs rendered in SVG, the PointSize has been made more closely match Mathematica.
  • Polygons rendered in Asymptote now respects the even/odd rule for filling areas.

Density Plots rendered in SVG broke with this release. They will be reinstated in the future.

Documentation

Go over settings file to ensure usage names are full sentences.

We have started to put more builtins in the sections or subsections following the organization in Mathematics 5 or as found in the online Wolfram Language Reference. As a result, long lists in previous topics are a bit shorter and there are now more sections. This work was started in 2.2.0.

More work is needed on formatting and showing this information, with the additional breakout we now have subsections. More reorganization and sectioning is needed.

These cleanups will happen in a future version.

Chapters without introductory text like Structural Operations, or Tensors have had descriptions added.

Sections that were empty have either been expanded or removed because the underlying name was never a user-level built in, e.g. the various internal Boxing functions like DiskBox, or CompiledCodeBox

Documentation specific builtins like PolarPlot or BernsteinBasis have been added improved, and document examples have been revised such as for PieChart, Pi and others.

The Mathics Gallery examples have been updated.

Some slight improvements were made to producing the PDF and more kinds of non-ASCII symbols are tolerated. Expect more work on this in the future via tables from the Mathics Scanner project.

Chapters are no longer in Roman Numerals.

Internal changes

  • docpipline.py accepts the option --chapters or -c to narrow tests to a particular chapter
  • Format routines have been isolated into its own module. Currently we have format routines for SVG, JSON and
    Asymptote. Expect more reorganization in the future.
  • Boxing routines have been isolated to its own module.
  • The entire code base has been run through the Python formatter black.
  • More Python3 types to function signatures have been added.
  • More document tests that were not user-visible have been moved to unit tests which run faster. More work is needed here.
