Fantastic!  That's really cool.  It would be great to have examples
accessible from the main sagemath.org 
webpage---that way people could get a taste of Sage (and particularly
the interacts!) without having to install it or make an account on
sagenb.org .



We're just polishing up the last little bits for a Sage Cell Server 1.0 
release.  The plan is to advertise it like crazy then.  Of course, you 
can use it now if you'd like.


Thanks,

Jason

I responded to the github issue, but: the problem seems fixed. So
Unicode/UTF-8 stuff should work. (Although I didn't try any other
encoding or fancy string stuff.)

That would be great for touch devices (where typing is very hard), or

These all sound like CodeMirror 2 problems.  We should upgrade our 
Codemirror 2, as it is way behind the current codemirror now.


Even for the extra line bit in other messages---those examples also fail

without the extra line at the end, which again indicates that there is 
some sort of CodeMirror 2 issue.

Unicode should work now.  The main problem was that 
sage.misc.preparser.preparse_file explicitly sees if the string is of 
type 'string' (rather than basestring), so it was kicking out all 
unicode.  So now we just pass an utf8 encoded string.

This one?

@interact

print n^2

It works fine for me without any extra newline at the end (so the code 
ends directly after the 2).


Can you paste the messages, exactly what the error is, etc?

Yes, it's codemirror 2.  The codemirror 2 developer has made some 
changes recently to get it to work better on iOS, so maybe upgrading 
would help Android as well.  Regardless, we put the option to switch to 
plain text for situations like this (click the link under the editor).

It was.   I got this on both my iphone and gtab.   It is a very serious

Can you give an example?  Already, we add a newline to work around this

The "print n*n" @interact from the recent singlecell thread works great
on my Nexus S (Android 2.3.4) with the stock browser.


Great!




I did discover a problem, though: I tried this

@interact
def f(n=(1..10)):
 print n*n, '한'

In the ordinary notebook (Sage 4.7.2), it works as expected. But on
aleph.sagemath.org, I get a blank output, on both my Android phone and
in Chrome on my Macbook. It doesn't print any messages, I just get a
blank line. I get the same thing if I write u'한'.

It works if I use '\xed\x95\x9c'.

Is this expected? I'm fine if the answer is "UTF-8/Unicode input isn't
supported yet."



Uh, maybe.  I don't know.  Can you open an issue on github?  I'm not 
sure where there would be an error, but surely if there is no output, 
there is a traceback printed somewhere.

Sliders don't work on Android 2.3 (Gingerbread) for me in the sense that
they're not draggable - I can click somewhere along the slider range
and the slider will move there, but there's no "sliding" animation.

Buttons appear to work fine.

Unfortunately I don't own an iOS device (which is what this library
appears to prioritize support for).


Yes, that's what the developer has.  John Travis reported to me that it 
worked on his Android device (I don't know what version, and I don't 
know if he tried dragging sliders).  If anyone knows how the touch 
events work in the browser, I'm sure the library author would accept 
pull requests.

Jason
