)

When you run from the command prompt "cython -a ..." you get a really nice
HTML file with yellow shading to indicate slow python operations vs fast C
operations. You also get this same HTML file as a link every time you
compile Cython code in Sage. My questions are: (1) Can I get this HTML file
if I'm compiling using distutils? (2) Can I get this HTML file if I'm
compiling using pyximport? Thanks in advance!!

Yes, pass "annotate=True" into cythonize().

I don't think there's a direct option for that in pyximport, but you can
always import Cython yourself and set the option globally in the Options
module.

Or if not using cythonize(), you can set the flag

Cython.Compiler.Options.annotate = True

which is not documented anywhere as far as I can see

Thanks! I put up those answers at stackoverflow in case anyone else is
searching for it.

When I was digging through the source on Github, it seemed to me that you
should be able to pass cython_directives={"annontate": True} as kwarg in
Cython.distutils.Extension, but when I tried it it didn't work. Any
thoughts?

I've gotten it to work by using `ext_modules = cythonize(...,
annotate=True)` as shown on
 http://docs.cython.org/src/reference/compilation.html

Yes that does work. I was just wondering about the Extension class
specifically. I suppose in the end it doesn't matter. I should probably
just use "cythonize" anyway.

Fundamentally the distutils Extension class doesn't know anything about
Cython unless you use the Cython provided build_ext command.  I've found
its usually easier to use cythonize which processes the pyx source and
returns an Extension that distutils knows how to process.

Only drawback is that the pyx -> c conversion is run, even if you do
something like `python setup.py clean`.

A patch solving this issue would be very welcome! (I'm not sure the
best way to detect this...)
