build_helpers.py script

Build helpers for setup.py.

Includes package dependency checks and monkey-patch to numpy.distutils to work with Cython.

Notes

The original version of this file was adapted from NiPy project [1].

class build_helpers.Clean(dist)[source]

Distutils Command class to clean, enhanced to clean also files generated during python setup.py build_ext –inplace.

run(self)[source]

A command’s raison d’etre: carry out the action it exists to perform, controlled by the options initialized in ‘initialize_options()’, customized by other commands, the setup script, the command-line, and config files, and finalized in ‘finalize_options()’. All terminal output and filesystem interaction should be done by ‘run()’.

This method must be implemented by all command classes.

class build_helpers.DoxygenDocs(dist)[source]
description = 'generate docs by Doxygen'
run(self)[source]

A command’s raison d’etre: carry out the action it exists to perform, controlled by the options initialized in ‘initialize_options()’, customized by other commands, the setup script, the command-line, and config files, and finalized in ‘finalize_options()’. All terminal output and filesystem interaction should be done by ‘run()’.

This method must be implemented by all command classes.

class build_helpers.NoOptionsDocs(dist)[source]
finalize_options(self)[source]

Set final values for all the options that this command supports. This is always called as late as possible, ie. after any option assignments from the command-line or from other commands have been done. Thus, this is the place to code option dependencies: if ‘foo’ depends on ‘bar’, then it is safe to set ‘foo’ from ‘bar’ as long as ‘foo’ still has the same value it was assigned in ‘initialize_options()’.

This method must be implemented by all command classes.

initialize_options(self)[source]

Set default values for all the options that this command supports. Note that these defaults may be overridden by other commands, by the setup script, by config files, or by the command-line. Thus, this is not the place to code dependencies between options; generally, ‘initialize_options()’ implementations are just a bunch of “self.foo = None” assignments.

This method must be implemented by all command classes.

user_options = [('None', None, 'this command has no options')]
class build_helpers.SphinxHTMLDocs(dist)[source]
description = 'generate html docs by Sphinx'
run(self)[source]

A command’s raison d’etre: carry out the action it exists to perform, controlled by the options initialized in ‘initialize_options()’, customized by other commands, the setup script, the command-line, and config files, and finalized in ‘finalize_options()’. All terminal output and filesystem interaction should be done by ‘run()’.

This method must be implemented by all command classes.

class build_helpers.SphinxPDFDocs(dist)[source]
description = 'generate pdf docs by Sphinx'
run(self)[source]

A command’s raison d’etre: carry out the action it exists to perform, controlled by the options initialized in ‘initialize_options()’, customized by other commands, the setup script, the command-line, and config files, and finalized in ‘finalize_options()’. All terminal output and filesystem interaction should be done by ‘run()’.

This method must be implemented by all command classes.

build_helpers.generate_a_pyrex_source(self, base, ext_name, source, extension)[source]

Monkey patch for numpy build_src.build_src method

Uses Cython instead of Pyrex.

build_helpers.get_sphinx_make_command()[source]
build_helpers.have_good_cython()[source]
build_helpers.package_check(pkg_name, version=None, optional=False, checker=<class 'distutils.version.LooseVersion'>, version_getter=None, messages=None, show_only=False)[source]

Check if package pkg_name is present, and in correct version.

Parameters
pkg_namestr or sequence of str

The name of the package as imported into python. Alternative names (e.g. for different versions) may be given in a list.

versionstr, optional

The minimum version of the package that is required. If not given, the version is not checked.

optionalbool, optional

If False, raise error for absent package or wrong version; otherwise warn

checkercallable, optional

If given, the callable with which to return a comparable thing from a version string. The default is distutils.version.LooseVersion.

version_gettercallable, optional:

If given, the callable that takes pkg_name as argument, and returns the package version string - as in:

``version = version_getter(pkg_name)``

The default is equivalent to:

mod = __import__(pkg_name); version = mod.__version__``
messagesdict, optional

If given, the dictionary providing (some of) output messages.

show_onlybool

If True, do not raise exceptions, only show the package name and version information.

build_helpers.recursive_glob(top_dir, pattern)[source]

Utility function working like glob.glob(), but working recursively and returning generator.

Parameters
topdirstr

The top-level directory.

patternstr or list of str

The pattern or list of patterns to match.
