boltons
=======

*boltons should be builtins.*

**Boltons** is a set of pure-Python utilities in the same spirit as —
and yet conspicuously missing from — the `the standard library`_,
including:

  * :func:`Atomic file saving <boltons.fileutils.atomic_save>`, bolted on with
    :mod:`~boltons.fileutils`
  * A highly-optimized :class:`~boltons.dictutils.OrderedMultiDict`,
    in :mod:`~boltons.dictutils`
  * Two types of :class:`~boltons.queueutils.PriorityQueue`, in
    :mod:`~boltons.queueutils`
  * :func:`Chunked <boltons.iterutils.chunked>` and
    :func:`windowed <boltons.iterutils.windowed>` iteration, in
    :mod:`~boltons.iterutils`
  * A full-featured :class:`~boltons.tbutils.TracebackInfo` type, for
    representing stack traces, in :mod:`~boltons.tbutils`

And that's just a small selection. As of |today|, ``boltons`` is
|b_type_count| types and |b_func_count| functions spread across
|b_mod_count| modules.

.. counts are appx 50, 75, and 23, respectively, as of initial docs writing

.. _the standard library: https://docs.python.org/2.7/library/index.html

Installation and Integration
----------------------------

Boltons can be added to a project in a few ways. There's the obvious one::

  pip install boltons

Then dozens of boltons are just an import away::

  from boltons.cacheutils import LRU
  my_cache = LRU()

Due to the nature of utilities, application developers might want to
consider other integration options. See the :ref:`Integration
<arch_integration>` section of the architecture document for more
details.

Boltons is tested against Python 2.6, 2.7, 3.4, and PyPy.

Third-party packages
--------------------

The majority of boltons strive to be "good enough" for a wide range of
basic uses, leaving advanced use cases to Python's `myriad specialized
3rd-party libraries`_. In many cases the respective ``boltons`` module
will describe 3rd-party alternatives worth investigating when use
cases outgrow ``boltons``. If you've found a natural "next-step"
library worth mentioning, :ref:`consider filing an issue <Gaps>`!

Gaps
----

Found something missing in the standard library that should be in
``boltons``? Found something missing in ``boltons``? First, take a
moment to read the very brief :doc:`architecture` statement to make
sure the functionality would be a good fit.

Then, if you are very motivated, submit `a Pull Request`_. Otherwise,
submit a short feature request on `the Issues page`_, and we will
figure something out.
