CHANGES

10.0.0

April 19, 2026

Supports Python 3.14. Python 3.10 support dropped. Python 3.10 may still work, but it's not supported.

Track API changes in mathics-core and Mathics3-scanner.

Fix bug in --full-form handling.

Allow matplotlib to render TeXForm output. This is done if Settings`$RenderTeXForm is True and matplotlib is installed. Settings`$RenderTeXForm is set to True by default.

Bugs

  1. PR 108 Restrict shell escape (!) when sandboxed

9.0.0

August 29, 2025

Supports Python 3.13. Python 3.8 and 3.9 support dropped.

Track API changes in Mathics3 Scanner 9.0.0

Make CLI options more like wolframscript. This is an incompatible change. Single-dash long options like -help, -file are now accepted. Short option -f is associated with -file rather than --fullform; -F is is now used for Fullform. Option --read with alias -r is now -code and short option -c.

Toggling Autobrace using function key F4 was fixed; Function key F1 gives some rudimentary help in the bottom bar.

Match "(" with ")" in prompt-toolkit mode

Bugs

  • #82 Work around a bug giving Set:setraw error

This release tracks the API changes in the Mathics3 Kernel, and to support enhanged debugging

  • --edit-mode [emacs|vi] or was added to mathicsscript to specify which initial edit mode for prompt-toolkit to start in
  • --post-mortem was added mathicsscript to go into a trepan3k debugger on error
  • Add aliases for all of the 100 or so "no-meaning" operators
  • Allow 2D rendering from asymptote

7.0.0

Aug 10, 2025

  • Adjust for Mathics3 core 7.0.0 API
  • Drop support for 3.6 and 3.7 and add support for 3.11
  • Use pyproject.toml for packaging to be able to support 3.12

6.0.0

  • Adjust for Mathics3 core 6.0.0 API

5.0.0

  • Adjust for Mathics3 core 5.0.0 API
  • Fixed autobrace and rewritten with Condition from prompt_toolkit.filter
  • Add $GroupAutoComplete setting (default True) to disable completing closer group symbol. Feature provided by DUO Labs and Alessandro Piras.
  • Remove bindings for the right brackets
  • For prompt-toolkit and GNU Readline users, we allow a user input binding file in CONFIGDIR/inputrc (e.g. ~/.config/mathicsscript/inputrc). You can set the location this file via environment variable MATHICS_INPUTRC
  • Handle version-getting timeout better
  • Python 3.6 tolerance
  • Create code of conduct
  • Some code linting

4.0.0

  • Handle images via PNG and matplotlib
  • Packaging: include matplotlib in full install
  • Customize Asymptote configuration and add a psviewer that removes eps trash
  • Bump minimum Mathics3 core version to 4.0.0
  • Bug fix: Check if self has session attribute in asy.__del__

3.3.1

  • Packaging issues: getting settings.m file into distribution and other missing files
  • More pervasive handling of import errors

3.3.0

  • 3D Graphics is now handled if Asymptote is installed.
  • `Settings`$UseMatplotlib` and `Settings`$UseAsymptote` were added. The can disable the use of matplotlib and Asymptote when those are available.

3.2.1

Fix packaging issues and be more tolerant matplotlib errors.

3.2.0

  • Many 2D plots and graphs can now be viewed via a matplotlib shell! PR #40.
  • In prompt-toolkit:
    • Better word-boundary detection for NamedCharacters, Symbols
    • Include grouping start symbols "(", "{", "[" in detection

3.1.0

Word completion detection was improved slightly. Previously, a grouping opener like "[", "(", or "{" would prevent word completion.

ASCII to unicode conversion was disabled since it was flaky and turned === into garbage upon seeing ``==`. Issue #38

In prompt-readline by default, inserting a "[", "(", or "{" will automatically insert the corresponding closing "]", ")", and "}". Use f3 to toggle this behavior.

The packaging of 3.0.0 omitted some Readline inputrc files, and a JSON operator table. Issue #37 A few other Python packaging problems were fixed.

We've separated prompt_readline functions into its own module separate from the common prompt readline functions

3.0.0

The primary readline interface has been redone using the excellent [prompt-toolkit](https://pypi.org/project/prompt-toolkit/). This is pure Python code so it should be available everywhere. We still include GNU-Readline for those situations where prompt-toolkit doesn't work. Select the readline style now with the --choice` option which can be one of GNU, Prompt, or None.

Prompt toolkit allows us to color input as it is getting typed. It also has nicer completion facilities, and sports a bottom modeline status bar.

There is still a bit of cleanup work to do to support GNU readline inputrc files better, or to handle completion better, but this will come later.

Independent of prompt-toolkit, there better pygments colorization using [mathics-pygments](https://pypi.org/project/prompt-toolkit/). Expect that to improve over time too.

2.2.0

  • There are now system setting and user settings. User settings take precedence over system settings.
  • String output is now shown in quotes to make it more distinguishable from symbol and unexpanded expressssion output. This does not follow how wolframscript works. Option strict-wl-output will disable this.
  • Syntax and Highlighting is now done via the Python [mathics-pygments](https://pypi.org/project/mathics-pygments/) package. I think you'll find colorization more complete and useful. Expect more improvements as mathics-pygments improves.
  • Flag --initfile is now --run to have better conformance with wolframscript. In the future we hope to support support conformance with wolfram if the`` mathicsscript`` (or code underneath) is called using the name mathics3.

2.1.2

  • Packaging changes. Make sure egg/wheel/tarball has settings.m and GNU Readline inputrc files package
  • Bump minimum Mathics-Scanner version. There was a small subtle bug in infix Function operators in that

2.1.1

Administrative changes but necessary to get this working properly:

  • Bump min version of mathicsscanner. There was a bug in mathicsscanner that prevented

the GNU Readline inputrc files from getting created properly. * Include settings.m in distribution. There was a typo in setup.py for location of this file.

2.1.0

  • Allow command-line flag -c as an alias for --execute (along with -e to be compatible with wolframscript
  • Better compliance on Windows which are GNU readline-starved
  • Better unicode detection
  • Accept newer mathics-scanner and Mathics3 versions

2.0.1

  • Fix mathicsscript -f FILE argument. See PR #26

2.0.0

  • All escape sequence for unicode and letter names added for GNU Readline
  • Use Mathics3 Scanner package
  • Support XDG-style configuration files

1.1.2

  • Fix `Settings`$ShowFullForm` now that we use Mathics3 supports Booleans better
  • Show mathicsscript version on startup
  • Add `Settings`MathicsScriptVersion
  • Add all of the WL escape sequences
  • Add conversions from WL Unicode to standard Unicode
  • Shell escapes ! and !! added

Incompatible changes:

  • -e --execute is better suited for embedded use. It adds --quiet and shows just evaluation output as text

1.1.1

  • We require Mathics3 1.1.1 for features added in that to support unicode and user-formatting
  • Start to support Unicode as a CLI option: --unicode/--no-unicode. The setting name is `Settings`$UseUnicode.
  • Add a lot of Unicode symbols and the WL esc sequences. For example letters with dots under them. These are the "Formal" parameters/letters.
  • Handle Unicode versus WL character code mismatches, , in particular Unicode directed and undirected edges.
  • Support for `PyMathics`Graph` (to be released on PyPI soon).
  • Some XDG compatibility
  • Toleratte MS/Windows pyreadline which doesn't handle remove_history_item
  • Show pygments styles when an invalid one is given
  • Use "inkpot" for dark backgrounds and "colorful" for light backgrounds.
  • Add `Settings`PygementsStylesAvailable
  • Add settings.m to holds mathicsscript`a`-specific definitions ``Settings and their default values. Settings include - `Settings`$ShowFullFormInput - `Settings`$PygmentsStyle - `Settings`$PygmentsShowTokens - `Settings`$UseUnicode` (also mentioned above)

A lot of code for handling graph formatting is here but will eventually be moved to a backend formatting module which hasn't been written yet.

1.1.0

Now that Mathics3 1.1.0 is released depend on that.

Some internal preparation work was done to support changing settings inside the REPL. Not ready for release yet.

1.1.0 rc1

Split off from plain mathics script.

  • GNU Readline terminal interaction. This includes
    • saving command history between sessions.
    • variable completion, even for symbol names like \\[Sigma]
    • limited ESC keyboard input; for example esc `p` esc is π
  • Syntax highlighting using pygments.
  • Automatic detection of light or dark terminal background color.
