我们从Python开源项目中，提取了以下50个代码示例，用于说明如何使用pip._vendor.packaging.utils.canonicalize_name()。
def _get_index_urls_locations(self, project_name): """Returns the locations found via self.index_urls Checks the url_name on the main (first in the list) index and use this url_name to produce all locations """ def mkurl_pypi_url(url): loc = posixpath.join( url, urllib_parse.quote(canonicalize_name(project_name))) # For maximum compatibility with easy_install, ensure the path # ends in a trailing slash. Although this isn't in the spec # (and PyPI can handle it without the slash) some other index # implementations might break if they relied on easy_install's # behavior. if not loc.endswith('/'): loc = loc + '/' return loc return [mkurl_pypi_url(url) for url in self.index_urls]
def fmt_ctl_handle_mutual_exclude(value, target, other): new = value.split(',') while ':all:' in new: other.clear() target.clear() target.add(':all:') del new[:new.index(':all:') + 1] if ':none:' not in new: # Without a none, we want to discard everything as :all: covers it return for name in new: if name == ':none:': target.clear() continue name = canonicalize_name(name) other.discard(name) target.add(name)
def _get_candidates(self, link, package_name): can_not_cache = ( not self.cache_dir or not package_name or not link ) if can_not_cache: return [] canonical_name = canonicalize_name(package_name) formats = index.fmt_ctl_formats( self.format_control, canonical_name ) if not self.allowed_formats.intersection(formats): return [] root = self.get_path_for_link(link) try: return os.listdir(root) except OSError as err: if err.errno in {errno.ENOENT, errno.ENOTDIR}: return [] raise
