clique

clique.DIGITS_PATTERN = '(?P<index>(?P<padding>0*)\\d+)'

Pattern for matching an index with optional padding.

clique.PATTERNS = {'frames': '\\.(?P<index>(?P<padding>0*)\\d+)\\.\\D+\\d?$', 'versions': 'v(?P<index>(?P<padding>0*)\\d+)'}

Common patterns that can be passed to assemble().

clique.assemble(iterable, patterns=None, minimum_items=2)[source]

Assemble items in iterable into discreet collections.

patterns may be specified as a list of regular expressions to limit the returned collection possibilities. Use this when interested in collections that only match specific patterns. Each pattern must contain the expression from DIGITS_PATTERN exactly once.

A selection of common expressions are available in PATTERNS.

Note

If a pattern is supplied as a string it will be automatically compiled to a re.RegexObject instance for convenience.

When patterns is not specified, collections are formed by examining all possible groupings of the items in iterable based around common numerical components.

minimum_items dictates the minimum number of items a collection must have in order to be included in the result. The default is 2, filtering out single item collections.

Return tuple of two lists (collections, remainder) where ‘collections’ is a list of assembled Collection instances and ‘remainder’ is a list of items that did not belong to any collection.

clique.parse(value, pattern='{head}{padding}{tail} [{ranges}]')[source]

Parse value into a Collection.

Use pattern to extract information from value. It may make use of the following keys:

  • head - Common leading part of the collection.
  • tail - Common trailing part of the collection.
  • padding - Padding value in %0d format.
  • range - Total range in the form start-end
  • ranges - Comma separated ranges of indexes.
  • holes - Comma separated ranges of missing indexes.

Note

holes only makes sense if range or ranges is also present.
