KirbyBase 1.4 is now available at: http://www.netpromi.com/files/KirbyBase-1.4.zip What is KirbyBase? KirbyBase is a simple, pure-Python, plain-text, flat-file database management system that can be used either embedded in your application or in a client/server, multi-user mode. To find out more about KirbyBase, go to: http://www.netpromi.com/kirbybase.html Changes: Added two new database field types: datetime.date and datetime.datetime. They are stored as strings, but are input and output as instances of datetime.date and datetime.datetime respectively. You can use them just like any other field: you can use them as selection criteria (i.e. db.select('plane.tbl', ['began_service'], ['>=%s' % datetime.date(1937,12,31)) or use them to specify the sort order of the result set of a select statement (i.e. db.select('plane.tbl', ['name'], ['.*'], sortField='range', ascending=False)). Made a few internal optimizations when running queries that have resulted in a 15-20% speed increase when doing large queries or updates. Changed the name of all private methods from starting with two underscores to starting with one underscore based on a discussion in comp.lang.python as to how to properly name private variables.
