Great job! > achievement of making it run over Jython (congratulations to those who > have made it possible !). The editor and the engine are available at, Many thanks goes to Philip Jenvey (who sat with me at the Google where we identified many bugs and he then fixed many of them) and Frank Wierzbicki (who fixed a lot of things in the last weeks/months) from Jython. > respectively: > > http://downloads.sourceforge.net/jscl-meditor/meditor3.0.zip > http://downloads.sourceforge.net/jscl-meditor/meditor3.0-sympy.zip > > The editor's operation is to evaluate/execute selected expressions/code > fragments, and additionally it can: > > - render MathML expressions that are copy/pasted to it (as far as I can > see, SymPy can output LaTeX code, is MathML planned ?) It is already implemented: In [2]: from sympy.printing.mathml import print_mathml In [3]: print_mathml(x+sin(x)) <apply> <plus/> <apply> <sin/> <ci> x </ci> </apply> <ci> x </ci> </apply> Only for some reason it is not exported by default.

Any feedback is very welcome ! Is there any documentation how to run it? I followed the docs/readme.txt: $ chmod +x bin/meditor $ bin/meditor docs/examples/sympy/example.py The editor starts up, I clicked Evaluate and I got a message "java.lang.NullPointerException". Am I doing something wrong? I use openjdk-6 from Debian.
