Helpers Module

This module regroups various helper functions which you can use when defining your custom processors or renderers.

Regular Expresssions Helpers:

The following helpers are convenience shortcuts for manipulating regex matches when handling custom tags.

tie.helpers.get_single_group(match, key=1)

Return one and only one group from the passed match object. If no group was defined in the matched regexp, return the whole match.

Parameters:

• match:

  A re.match object to extract the group from.

• key:

  Optionnal key argument to get a specific group. This can be either a list index or a string to get a named group. (See the re.MatchObject.group() method’s documentation if you don’t know how to get a specific group from a match object). Defaults to 1, to return the first defined group in the matching regex.
