Message-ID: <AANLkTinb55kQ=jLK6qgDhkB+gBV--XH2i7nOJD_5gf3i@mail.gmail.com>

The cython documentation is now part of the main repository, see
https://github.com/cython/cython/tree/master/docs .
https://github.com/cython/cython-docs should no longer be used
(perhaps it should be removed entirely, are there any/many inbound
links?)

from this fix: http://trac.cython.org/cython_trac/ticket/597 . When I
run "python3 setup.py install --user", I get an error:

Actually, I get this same error when I try to build with python-2.7 as well.

Subject: [Cython] "Cython's Users Guide"
Message-ID: <BANLkTin6JRCYWCgZehKGuDxaFzfzKwNUaQ@mail.gmail.com>

Hi,

I'm teaching Cython in my Sage course yet again, and noticed that
again there are some very confusing aspects of the Cython
documentation organization, which could probably be improved by a few
simple changes.

  1. At http://cython.org/ there is a big link in the middle of the
page labeled "Cython Users Guide" which goes to
http://docs.cython.org/.   However, http://docs.cython.org/ is *not*
the users guide -- it is "Cython?s Documentation".     In fact, the
Users Guide is Chapter 3 of the documentation.

  2. Looking at http://docs.cython.org, we see that Chapter 2 is
"Tutorials".  But then looking down to Chapter 3 we see that it is
"Cython Users Guide".  Of course, that's what one is after having just
clicked a link called "Cython Users Guide".  So we click on "Cython
Users Guide" again.

  3. We arrive at a page that again has "Tutorial" as Chapter 2.   For
some reason this makes me feel even more confused.

Recommend changes:

  1. Change the link on the main page from "Cython Users Guide" to
"Documentation"  or put a direct link into the Users Guide, or have
two links.

  2. At http://docs.cython.org/ rename the "Cython Users Guide" to
"Users Guide", since it is obviously the Cython Users Guide at this
point and "Cython documentation" is in the upper left of the page
everywhere.

  3. Possibly rename the tutorial in chapter 2 of the users guide to
something like "First Steps" or "Basic Tutorial" or something.

Do I want things to be yellower or whiter?

If I add an annotation and the colours don't change then I guess it's doing 
nothing, right.

Subject: [Cython] On cdef extern from syntax
Message-ID: <BANLkTikjWU_Rs5wdhhWhm5cmd9VFUkTDdg@mail.gmail.com>

Hi,

I was wondering if has been ever discussed to implement the cython
cdef extern from syntax as a with statement:

with cython.header_importer("") as cy:
       cy.ctypedef(" unsigned int uint8 ")
       cy.cfunc( " void * myfunc() )")

or also

with cython.header_importer("") as cy:
     cy("""
     ctypdef  ...

     """)

Maybe there is already something like that ?
