To: IPython developers list <ipyth...@scipy.org>

    Hi,

    New release of IPython for Sailfish OS (used by the Jolla smartphone, Nokia N9 and Nexus 4), as well as for Mer & Nemo Mobile & Plasma Active.

    IPython 2.0.0 is released with full terminal and Notebook interfaces. See this post in topic "IPython (terminal, Notebook) 2.0.0 for Sailfish " of Talk Maemo.org forum, it also includes screenshots :
http://talk.maemo.org/showthread.php?t=93139

    SymPy 0.7.5 :
http://talk.maemo.org/showthread.php?p=1424146#post1424146
and NumPy 1.7.1 :
https://openrepos.net/content/rcolistete/numpy-sailfish-os
are also available on Sailfish OS.

        Best regards from Brazil,

        Roberto

Nice.

Can we do anything about the incomplete Unicode support?
I'm thinking along the lines of letting each operator inspect the font
in use, check if the required Unicode characters are available, and
automatically fall back to ASCII art if there isn't.

Or maybe we can package a useful fallback font. Or supply one on the
SymPy website.

Just tossing around ideas, I have no real knowledge about Python's or
SymPy's font handling.

Hi,

Using "init_printing(use_unicode=false)" is a workaround. The
problem is the "Terminal" (FingerTerm) in Sailfish has fixed font type.
On other applications (a Qt/QML software) using SymPy, we can usually
choose a font type with complete Unicode support (like "DejaVu Sans Mono").

On Sunday I've sent my suggestion to Sailfish OS developers at Jolla :
"So I repeat my suggestion below, to have "DejaVu Sans Mono" font
available in Sailfish OS. And FingerTerm able to change the font."

Regards,

Roberto

    Hi,

    I haven't yet promoted SymPy 0.7.5 for Sailfish in this SymPy group because I was waiting to document it better in the Talk Maemo.org topic, with more comments, screenshots, etc. And I will also release an user-friendly rpm package  : SymPy icon launching Terminal with isympy, including Terminal, IPython 2.0.0 and SymPy 0.7.5 as dependencies. I will share here these new features when ready.

    Anyway, despite the Unicode issue in Terminal, SymPy 0.7.5 runs very well on Sailfish OS, including on IPython 2.0.0 terminal and Notebook interfaces.

    I am trying to package MatPlotLib for Sailfish, so SymPy could produce nice 2D and 3D plots.

        Regards,

        Roberto

I don't remember if it is documented in the docs, but DejaVu Sans Mono
is the font I like to recommend. It has the best support for the math
symbols we use (e.g., it is the only font I've tried that renders the
integral extension character long enough so that Integral(x) renders
as a single unbroken line), and is a good monospace font otherwise.
