This may be the last update before some major refactoring and interface
changing occurs.

In a future 2.0.0 release, Django will no longer be bundled here. See mathics-django for the unbundled replacement.

Some changes were made to support Pymathics Graph, a new graph package bundled separately, and to support the ability for front-ends to handle rendering on their own. Note that currently this doesn't integrate well nto the Django interface, although it works well in mathicsscript.

Package Updates

  • sympy 1.7.1

Mathics Packages added:

  • DiscreteMath`CombinatoricaV0.9 (preferred) aand
    DiscreteMath`CombinatoricaV0.6.

Both of these correspond to Steven Skiena's older book: "Implementing Discrete Mathematics: Combinatorics and Graph Theory" book.

If you have a package that you would like included in the distribution, and it works with Mathics, please contact us.

Rubi may appear in a future release, possibly in a year or so. However this might be speeded up if we can get people to help out with this.

New builtins:

  • StirlingS1, StirlingS2 (not all WL variations handled)

  • MapAt (not all WL variations handled)

  • PythonForm, SympyForm: these is not in WL. It simply will show a crude translation to sympy or python. Expect more and better translation later

  • Throw and Catch

  • With

  • FileNameTake

Enhancements and Bug fixes:

  • Workaround for Compile so it accepts functions ##1026
  • Add Trace option to Get. Get["fn", Trace->True] will show lines as they are read.
  • Convert to/from Boolean types properly in from_python, to_python. Previously they were 0, and 1.
  • Extend DeleteCases to accept a levelspec parameter.
  • Set Evaluation#exc_result to capture Aborted, Timeout, Overflow1`, etc.
  • ImageData changed to get bits {0,1}, not booleans as previously.
  • Add tokenizer symbols for <-> and -> and the unicode versions of
    those.
  • Small corrections to Needs, e.g check if already loaded, correct a typo, etc.
  • System`$InputFileName is now set inside Needs and Get
  • Install shell scripts dmathicserver, dmathicsscript, and dmathics to simplify running docker
  • Adjust $InputFileName inside Get and Needs.
