Subpackage Descriptions
single *pathspec*: Path Specification ============================== *pathspec* is a utility library for pattern matching of file paths. So far this only includes Git's wildmatch pattern matching which itself is derived from Rsync's wildmatch. Git uses wildmatch for its `gitignore`_ files. .. _`gitignore`: Tutorial -------- Say you have a "Projects" directory and you want to back it up, but only certain files, and ignore others depending on certain conditions:: >>> import pathspec >>> # The gitignore-style patterns for files to select, but we're including >>> # instead of ignoring. >>> spec = """ ... ... # This is a comment because the line begins with a hash: "#" ... ... # Include several project directories (and all descendants) relative to ... # the current directory. To reference a directory you must end with a ... # slash: "/" ... /project-a/ ... /project-b/ ... /project-c/ ... ... # Patterns can be negated by prefixing with exclamation mark: "!" ... ... # Ignore temporary files beginning or ending with "~" and ending with ... # ".swp". ... !~* ... !*~ ... !*.swp ... ... # These are python projects so ignore compiled python files from ... # testing. ... !*.pyc ... ... # Ignore the build directories but only directly under the project ... # directories. ... !/*/build/ ... ... """ We want to use the GitWildMatchPattern class to compile our patterns. The PathSpec class provides an interface around pattern implementations:: >>> spec = pathspec.PathSpec.from_lines(pathspec.patterns.GitWildMatchPattern, spec.splitlines()) That may be a mouthful but it allows for additional patterns to be implemented in the future without them having to deal with anything but matching the paths sent to them. GitWildMatchPattern is the implementation of the actual pattern which internally gets converted into a regular expression. PathSpec is a simple wrapper around a list of compiled patterns. To make things simpler, we can use the registered name for a pattern class instead of always having to provide a reference to the class itself. The GitWildMatchPattern class is registered as **gitwildmatch**:: >>> spec = pathspec.PathSpec.from_lines('gitwildmatch', spec.splitlines()) If we wanted to manually compile the patterns we can just do the following:: >>> patterns = map(pathspec.patterns.GitWildMatchPattern, spec.splitlines()) >>> spec = PathSpec(patterns) ``PathSpec.from_lines()`` is simply a class method which does just that. If you want to load the patterns from file, you can pass the file instance directly as well:: >>> with open('patterns.list', 'r') as fh: >>> spec = pathspec.PathSpec.from_lines('gitwildmatch', fh) You can perform matching on a whole directory tree with:: >>> matches = spec.match_tree('path/to/directory') Or you can perform matching on a specific set of file paths with:: >>> matches = spec.match_files(file_paths) Or check to see if an individual file matches:: >>> is_matched = spec.match_file(file_path) License
