BeakerX kernel

A Symja MMA mode BeakerX kernel can be found in the Maven artifact:

• matheclipse-beakerx - Maven: snapshot JARS

Auto-complete of a function name is triggered in a SymjaMMA input cell, after the TAB key was pressed (i.e. type Int and get a list of suggestions to complete the function name).

The mode for the output cell format can be set with these "meta command" in a SymjaMMA input cell:

• /tex - the default output method for results. Creates a cell with mimetype text/latex
• /input
  • f[x, y] is printed as f[x, y]
  • floating point numbers like 0.75*10^-13 are printed as 7.50000*10^-14
• /output
  • f[x, y] is printed as f(x, y)
  • floating point numbers like 0.75*10^-13 are printed as 7.500000000000001E-14
• /traditional
  • f[x, y] is printed as f(x, y)
  • floating point numbers like 0.75*10^-13 are printed as 7.50000*10^-14
• /java - generate source codes which can be used as input in the Java kernel
• /timeouton - evaluations are timed out after 60 seconds
• /timeoutoff - evaluations aren't timed out

The last answer can be reused in the next input cell with the global $ans variable

Add line

from .symjamma_magic import *

to file Lib/site-packages/beakerx_magics/__init__.py

Lib/site-packages/beakerx_magics/symjamma_magic.py

Run beakerx install again, to get the kernel installed in the share folder:

[InstallKernelSpec] Installed kernelspec symjamma in C:\Users\dev\Anaconda3\share\jupyter\kernels\symjamma

Running BeakerX

Start it with

beakerx

and then use the “New” menu to create a notebook in the SymjaMMA language.
