## enable the SQLite history

#  By default, IPython will put the history database in the IPython profile
#  directory.  If you would rather share one history among profiles, you can set
#  this value in each, so that they are consistent.
#  
#  Due to an issue with fcntl, SQLite is known to misbehave on some NFS mounts.
#  If you see IPython hanging, try setting this to something on a local disk,
#  e.g::
#  
#      ipython --HistoryManager.hist_file=/tmp/ipython_hist.sqlite

# BaseFormatter(Configurable) configuration

## A base formatter class that is configurable.

#  This formatter should usually be used as the base class of all formatters. It
#  is a traited :class:`Configurable` class and includes an extensible API for
#  users to determine how their objects are formatted. The following logic is
#  used to find a function to format an given object.
#  
#  1. The object is introspected to see if it has a method with the name
#     :attr:`print_method`. If is does, that object is passed to that method
#     for formatting.
#  2. If no print method is found, three internal dictionaries are consulted
#     to find print method: :attr:`singleton_printers`, :attr:`type_printers`
#     and :attr:`deferred_printers`.
#  
#  Users should use these dictionaries to register functions that will be used to
#  compute the format data for their objects (if those objects don't have the
#  special print methods). The easiest way of using these dictionaries is through
#  the :meth:`for_type` and :meth:`for_type_by_name` methods.
#  
#  If no function/callable is found to compute the format data, ``None`` is
#  returned and this format type is not used.

#  If the object cannot be pretty printed, :func:`repr` is used. See the
#  documentation of :mod:`IPython.lib.pretty` for details on how to write pretty
#  printers.  Here is a simple example::
#

#              return p.text('dtype(...)')
