Problem to access C code

[bourba]

Hello.

I would like to access external C code so I have
exactly followed the example exposed in
http://www.sagemath.org/doc/html/tut/node51.html
(5.2.1 Accessing C Functions in Separate Files)

My directory "/home/mainuser/test_sage" contains
"test.c" plus "test.spyx" and when I type :

sage : load "/home/mainuser/test_sage/test.spyx"

then sage returns this error message:

Loading of file "/home/mainuser/test_sage/test.spy" has type not
implemented.

Thanks.

Hello,

What version of Sage are you using? I tried this on my local machine
and can't duplicate the error that you're getting.

Try changing the filename to test.pyx and see if that helps.

I've upgraded to 2.11.
I still get the same symptom while
sage runs on notebook mode *but*
when I launch SAGE on console the example
given by the tutorial works fine (with the .spyx
extension.) I can't see the link between
the notebook-interface causing problem when
cython is simultaneously working...

Is it possible to increase the verbosity
of the error message ?

Thanks.

I have the same problem, I have not tried the SAGE on the console.
I also want to do the same. Have you managed to solve the problem?

Thanks

Roger,

Dear Roger, dear bourba

Same for me: The console is fine, but the notebook doesn't work.

Two observations:
- Tab completion did not work in the notebook. When i entered
attach "/home/king/SAGE/te
and hit the tab-key, no completion (test.c or test.spyx) has been
suggested, although this works on the console
- The complaint is
Loading of file "/home/king/SAGE/test.spy" has type not implemented.
Note that it says "test.spy", not "test.spyx". As much as i remember,
there was a discussion on this in another thread.

I don't know if the two observations are related.

Yours
Simon

-> to Roger.

No. Unfortunately, I'm stuck.
I stay on console as an (uncomfortable)
workaround to use my C code.

This is not implemented. In fact, I never even thought of implementing this,
but it probably wouldn't be too hard.

The problem is that I never implemented this. I wish somebody would.
I bet it would be very easy, since we have %cython in the notebook.
In fact, it just occured to me that if you type

cython(open("/home/king/SAGE/test.spyx").read())

then that is 100% equivalent to what you would get from

load /home/king/SAGE/test.spyx

So, it's pretty easy to workaround that load thing not being implemented!

They are, where the relationship is just me not having
implemented something I should have.
