[Cython] Utilities, cython.h, libcython
Hey,
I briefly mentioned something about this in a pull request, but maybe
it deserves some actual discussion on the ML.
So I propose that after fused types gets merged we try to move as many
utility codes as possible to their utility code files (unless they are
used in pending pull requests or other branches). Preferably this will
be done in one or a few commits. How should we split up the work, any
volunteers? Perhaps people who wrote certain utilities also want to
move them? In that case, we should start a new branch and then merge
that into master when it's done.
We could actually move things before fused types get merged, as long
as we don't touch binding_cfunc_utility_code.
Before we go there, Stefan, do we still want to implement the header
.ini style which can list dependencies and such? I personally don't
care very much about it, but memoryviews and the utility loaders are
merged so if someone wants to take up that job, it'd be good to do
before moving the utilities.
Another issue is that Cython compile time is increasing with the
addition of control flow and cython utilities. If you use fused types
you're also going to combinatorially add more compile time. I'm sure
this came up earlier, but I really think we should have a libcython
and a cython.h. libcython (a shared library) should contain any common
Cython-specific code not meant to be inlined, and cython.h any types,
macros and inline functions etc. This will decrease Cython and C
compile time, and will also make executables smaller. This could be
enabled using a command line option to Cython, as well as with
