ANN: knife 0.5.1

[L. C. Rees]

knife is a powerful Python multitool loosely inspired by underscore.js
but remixed for maximum pythonicity. knife concentrates power normally
found dispersed across the universe of Python packages in one
convenient shrink-wrapped package.

knife works with Python 2.6, 2.7, and 3.2.

knife documentation can be found at http://readthedocs.org/docs/knife/en/latest/
or http://packages.python.org/knife/

3 second knife
---------------------

Things go in:

  >>> gauntlet = __(5, 4, 3, 2, 1)

Things get knifed:

  >>> gauntlet.initial().rest().slice(1, 2).last()

Things come out:

  >>> gauntlet.get()
  3

Slightly More
-------------------

knife features over 40 methods that can be chained into pipelines:

  >>> from knife import __
  >>> __(5, 4, 3, 2, 1).initial().rest().slice(1, 2).last().get()
  3

Or object-oriented style:

  >>> from knife import knife
  >>> oo = knife(('a', 1), ('b', 2), ('c', 3))
  >>> oo.wrap(dict)
  >>> oo.map()
  >>> oo.get()
  {'a': 1, 'b': 2, 'c': 3}

knife knives can roll thing in its pipeline back to the results of
the immediately preceding steps, a baseline snapshot, or even the
original
arguments.

  >>> undone = __(1, 2, 3).prepend(1, 2, 3, 4, 5, 6)
  >>> undone.peek()
  [1, 2, 3, 4, 5, 6, 1, 2, 3]
  >>> undone.append(1).undo().peek()
  [1, 2, 3, 4, 5, 6, 1, 2, 3]
  >>> undone.append(1, 2).undo(2).peek()
  [1, 2, 3, 4, 5, 6, 1, 2, 3, 1]
  undone.snapshot().append(1, 2).baseline().peek()
  [1, 2, 3, 4, 5, 6, 1, 2, 3, 1]
  undone.original().peek()
  [1, 2, 3]
  >>> one.original().minmax().pipe(two).merge().back().max().get()
  1000
  >>> one.original().minmax().pipe(two).merge().back().sum().get()
  1002
