NAME
====
cython_freeze.py - create a C file for embedding Cython modules
SYNOPSIS
========
cython_freeze.py module [...]
DESCRIPTION
===========
**cython_freeze.py** generates a C source file to embed a Python interpreter
with one or more Cython modules built in. This allows one to create a single
executable from Cython code, without having to have separate shared objects
for each Cython module.
A major advantage of this approach is that it allows debuging with gprof(1),
which does not work with shared objects.
Note that this method differs from ``cython --embed``. The ``--embed`` options
modifies the resulting C source file to include a ``main()`` function, so it
can only be used on a single Cython module. The advantage ``--embed`` is
simplicity. This module, on the other hand, can be used with multiple
modules, but it requires another C source file to be created.
EXAMPLE
=======
In the example directory, there exist two Cython modules:
cmath.pyx
A module that interfaces with the -lm library.
combinatorics.pyx
A module that implements n-choose-r using cmath.
Both modules have the Python idiom ``if __name__ == "__main__"``, which only
execute if that module is the "main" module. If run as main, cmath prints the
factorial of the argument, while combinatorics prints n-choose-r.
The provided Makefile creates an executable, *nCr*, using combinatorics as the
"main" module. It basically performs the following (ignoring the compiler
flags)::
$ cython_freeze.py combintorics cmath > nCr.c
$ cython combinatorics.pyx
$ cython cmath.pyx
$ gcc nCr.c -o nCr.o
$ gcc combinatorics.c -o combinatorics.o
$ gcc cmath.c -o cmath.o
$ gcc nCr.o combinatorics.o cmath.o -o nCr
Because the combinatorics module was listed first, its ``__name__`` is set
to ``"__main__"``, while cmath's is set to ``"cmath"``. The executable now
contains a Python interpreter and both Cython modules. ::
$ ./nCr
USAGE: ./nCr n r
Prints n-choose-r.
$ ./nCr 15812351235 12
5.10028093999e+113
PREREQUISITES
=============
Cython 0.11.2 (or newer, assuming the API does not change)
