Compile a Cython file. This converts a Cython file to a C (or C++ file),
and then compiles that. The .c file and the .so file are
created in a temporary directory.
INPUT:
- ``filename`` -- the name of the file to be compiled. Should end with
'pyx'.
- ``verbose`` (integer, default 0) -- level of verbosity. A negative
value ensures complete silence.
- ``compile_message`` (bool, default False) -- if True, print
``'Compiling <filename>...'`` to the standard error.
- ``use_cache`` (bool, default False) -- if True, check the
temporary build directory to see if there is already a
corresponding .so file. If so, and if the .so file is newer than the
Cython file, don't recompile, just reuse the .so file.
- ``create_local_c_file`` (bool, default False) -- if True, save a
copy of the ``.c`` or ``.cpp`` file in the current directory.
- ``annotate`` (bool, default True) -- if True, create an html file which
annotates the conversion from .pyx to .c. By default this is only created
in the temporary directory, but if ``create_local_c_file`` is also True,
then save a copy of the .html file in the current directory.
- ``sage_namespace`` (bool, default True) -- if True, import
``sage.all``.
- ``create_local_so_file`` (bool, default False) -- if True, save a
copy of the compiled .so file in the current directory.
OUTPUT: a tuple ``(name, dir)`` where ``name`` is the name
of the compiled module and ``dir`` is the directory containing
the generated files.
TESTS:
Before :trac:`12975`, it would have been needed to write ``#clang c++``,
but upper case ``C++`` has resulted in an error.
Using pkgconfig to find the libraries, headers and macros. This is a
work around while waiting for :trac:`22461` which will offer a better
solution::
sage: code = [
....: "#clang C++",
....: "from sage.rings.polynomial.multi_polynomial_libsingular cimport MPolynomial_libsingular",
....: "from sage.libs.singular.polynomial cimport singular_polynomial_pow",
....: "def test(MPolynomial_libsingular p):",
....: " singular_polynomial_pow(&p._poly, p._poly, 2, p._parent_ring)"]
sage: cython(os.linesep.join(code))
The function ``test`` now manipulates internal C data of polynomials,
squaring them::
sage: P.<x,y>=QQ[]
sage: test(x)
sage: x
x^2
Check that compiling C++ code works::
sage: cython("# distutils: language = c++\n"+
....: "from libcpp.vector cimport vector\n"
....: "cdef vector[int] * v = new vector[int](4)\n")
Check that compiling C++ code works when creating a local C file,
first moving to a tempdir to avoid clutter. Before :trac:`22113`,
the create_local_c_file argument was not tested for C++ code::
sage: d = sage.misc.temporary_file.tmp_dir()
sage: os.chdir(d)
sage: with open("test.pyx", 'w') as f:
....: _ = f.write("# distutils: language = c++\n"
....: "from libcpp.vector cimport vector\n"
....: "cdef vector[int] * v = new vector[int](4)\n")
sage: output = sage.misc.cython.cython("test.pyx", create_local_c_file=True)
Accessing a ``.pxd`` file from the current directory works::
sage: d = sage.misc.temporary_file.tmp_dir()
sage: os.chdir(d)
sage: with open("helper.pxd", 'w') as f:
....: _ = f.write("cdef inline int the_answer(): return 42")
sage: cython('''
....: from helper cimport the_answer
....: print(the_answer())
....: ''')
42
Warning and error messages generated by Cython are properly
handled. Warnings are only shown if verbose >= 0::
sage: code = '''
....: def test_unreachable():
....: raise Exception
....: return 42
....: '''
sage: cython(code, verbose=-1)
sage: cython(code, verbose=0)
warning: ...:4:4: Unreachable code

def _pyx_preparse(s):
r"""
Preparse a pyx file:
* parse ``clang`` pragma (c or c++)
* parse ``clib`` pragma (additional libraries to link in)
* parse ``cinclude`` (additional include directories)
* parse ``cfile`` (additional files to be included)
* parse ``cargs`` (additional parameters passed to the compiler)
The pragmas:
- ``clang`` - may be either ``'c'`` or ``'c++'`` indicating whether a C or
C++ compiler should be used
- ``clib`` - additional libraries to be linked in, the space separated list
is split and passed to distutils.
- ``cinclude`` - additional directories to search for header files. The
space separated list is split and passed to distutils.
- ``cfile`` - additional C or C++ files to be compiled. Also,
:envvar:`$SAGE_SRC` and :envvar:`$SAGE_LOCAL` are expanded, but other
environment variables are not.
- ``cargs`` - additional parameters passed to the compiler
OUTPUT: preamble, libs, includes, language, files, args
