scanf 1.3.3

A small scanf implementation

Python has powerful regular expressions but sometimes they are totally overkill when you just want to parse a simple-formatted string. C programmers use the scanf-function for these tasks (see link below).

This implementation of scanf translates the simple scanf-format into regular expressions. Unlike C you can be sure that there are no buffer overflows possible.

Original code from: http://code.activestate.com/recipes/502213-simple-scanf-implementation/

Modified original to make the %f more robust, as well as added %* modifier to skip fields.

Releases

1.0: 2010-10-11

• Initial release

1.1: 2010-10-13

• Changed regex from ‘match’ (only matches at beginning of line) to ‘search’ (matches anywhere in line)

• Bugfix - ignore cast for skipped fields

1.2: 2013-05-30

• Added ‘collapseWhitespace’ flag (defaults to True) to take the search string and replace all whitespace with regex string to match repeated whitespace. This enables better matching in log files where the data has been formatted for easier reading. These cases have variable amounts of whitespace between the columns, depending on the number of characters in the data itself.

1.3: 2016-01-18

• Added ‘extractdata’ function.

1.3.1 - 1.3.3: 2016-06-23

• Fixed various issues with metadata for PyPI
