fuzzyparsers 0.6

A collection of free-form input parsers (with special focus on dates)

The intent of the fuzzyparsers library is to provide a central place for functions to sanitize free form user input.

The library has two main parsers. The first is a prefix parser which compares a string to a list of strings and returns the unique element of the list which matches the prefix. An exception is thrown if the match is not unique.

>>> fuzzy_match(['aab','bba','abc'],'aa')
'aab'
>>> fuzzy_match(['aab','bba','abc'],'a')  # two strings starting with 'a'.
...
ValueError('ambiguous match',)

The second parser parses dates in various formats and returns a datetime.date object. Accepted formats include:

jan 12, 2003 jan 5 2004-3-5 +34 – 34 days in the future (relative to todays date) -4 – 4 days in the past (relative to todays date)

Fuzzyparsers is written by Joel B. Mohler and distributed under the terms of the GPL v2 (or later).

The doc-tests provide fair code coverage. Use the following command:

python -m doctest fuzzyparsers/*.py

To install fuzzyparsers, do the normal python thing (probably as root):

python setup.py install

or:
