  • Ticket #7377 – Description

    initial v45  
    1 This ticket is dependent on #6781, #7287.
    2 
    31With maxima-as-an-ecl-library and ecl accessible as a library, we can start interfacing with maxima via a binary library interface.
    42This should be more efficient and more robust, because expressions
    53can be transmitted in a much richer format than text and parsing does
    64not have to recognise error messages and questions (since communication does not go via STDIN/STDOUT anymore)

     8This ticket is dependent on #10743.

     10Update: The interface now passes a lot more doctests. Most failures are due to
     11 * small changes in floats, where they get transferred in binary form rather than via strings (simple to fix)
     12 * ECL only returns RuntimeErrors, since it can't see the difference. So doctests that test error reporting fail.
     13
     14Serious work issues:
     15 * How should derivatives, e.g. {{{D[0,1]f(x^2+y^2,x-y+3)}}} be translated to Maxima?
     16 * desolver interface is now broken
