distutils.misc_util

numpy.distutils.misc_util.all_strings(lst)[source]

Return True if all items in lst are string objects.

numpy.distutils.misc_util.allpath(name)[source]

Convert a /-separated pathname to one using the OS’s path separator.

numpy.distutils.misc_util.appendpath(prefix, path)[source]
numpy.distutils.misc_util.as_list(seq)[source]
numpy.distutils.misc_util.blue_text(s)[source]
numpy.distutils.misc_util.cyan_text(s)[source]
numpy.distutils.misc_util.cyg2win32(path: str) str[source]

Convert a path from Cygwin-native to Windows-native.

Uses the cygpath utility (part of the Base install) to do the actual conversion. Falls back to returning the original path if this fails.

Handles the default /cygdrive mount prefix as well as the /proc/cygdrive portable prefix, custom cygdrive prefixes such as / or /mnt, and absolute paths such as /usr/src/ or /home/username

Parameters
pathstr

The path to convert

Returns
converted_pathstr

The converted path

numpy.distutils.misc_util.default_config_dict(name=None, parent_name=None, local_path=None)[source]

Return a configuration dictionary for usage in configuration() function defined in file setup_<name>.py.

numpy.distutils.misc_util.dict_append(d, **kws)[source]
numpy.distutils.misc_util.dot_join(*args)[source]
numpy.distutils.misc_util.exec_mod_from_location(modname, modfile)[source]

Use importlib machinery to import a module modname from the file modfile. Depending on the spec.loader, the module may not be registered in sys.modules.

numpy.distutils.misc_util.filter_sources(sources)[source]

Return four lists of filenames containing C, C++, Fortran, and Fortran 90 module sources, respectively.

numpy.distutils.misc_util.generate_config_py(target)[source]

Generate config.py file containing system_info information used during building the package.

Usage:

config[‘py_modules’].append((packagename, ‘__config__’,generate_config_py))

numpy.distutils.misc_util.get_build_architecture()[source]
numpy.distutils.misc_util.get_cmd(cmdname, _cache={})[source]
numpy.distutils.misc_util.get_data_files(data)[source]
numpy.distutils.misc_util.get_dependencies(sources)[source]
numpy.distutils.misc_util.get_ext_source_files(ext)[source]
numpy.distutils.misc_util.get_frame(level=0)[source]

Return frame object from call stack with given level.

numpy.distutils.misc_util.get_info(pkgname, dirs=None)[source]

Return an info dict for a given C library.

The info dict contains the necessary options to use the C library.

Parameters
pkgnamestr

Name of the package (should match the name of the .ini file, without the extension, e.g. foo for the file foo.ini).

dirssequence, optional

If given, should be a sequence of additional directories where to look for npy-pkg-config files. Those directories are searched prior to the NumPy directory.

Returns
infodict

The dictionary with build information.

Raises
PkgNotFound

If the package is not found.

Examples

To get the necessary information for the npymath library from NumPy:

>>> npymath_info = np.distutils.misc_util.get_info('npymath')
>>> npymath_info                                    
{'define_macros': [], 'libraries': ['npymath'], 'library_dirs':
['.../numpy/core/lib'], 'include_dirs': ['.../numpy/core/include']}

This info dict can then be used as input to a Configuration instance:

config.add_extension('foo', sources=['foo.c'], extra_info=npymath_info)
numpy.distutils.misc_util.get_language(sources)[source]

Determine language value (c,f77,f90) from sources

numpy.distutils.misc_util.get_lib_source_files(lib)[source]
numpy.distutils.misc_util.get_mathlibs(path=None)[source]

Return the MATHLIB line from numpyconfig.h

numpy.distutils.misc_util.get_num_build_jobs()[source]

Get number of parallel build jobs set by the –parallel command line argument of setup.py If the command did not receive a setting the environment variable NPY_NUM_BUILD_JOBS is checked. If that is unset, return the number of processors on the system, with a maximum of 8 (to prevent overloading the system if there a lot of CPUs).

Returns
outint

number of parallel jobs that can be run

numpy.distutils.misc_util.get_numpy_include_dirs()[source]
numpy.distutils.misc_util.get_pkg_info(pkgname, dirs=None)[source]

Return library info for the given package.

Parameters
pkgnamestr

Name of the package (should match the name of the .ini file, without the extension, e.g. foo for the file foo.ini).

dirssequence, optional

If given, should be a sequence of additional directories where to look for npy-pkg-config files. Those directories are searched prior to the NumPy directory.

Returns
pkginfoclass instance

The LibraryInfo instance containing the build information.

Raises
PkgNotFound

If the package is not found.
