format()

lsst.pex.config.history.format	(		config,
			name = None,

Format the history record for a configuration, or a specific
configuration field.

Parameters
----------
config : `lsst.pex.config.Config`
    A configuration instance.
name : `str`, optional
    The name of a configuration field to specifically format the history
    for. Otherwise the history of all configuration fields is printed.
writeSourceLine : `bool`, optional
    If `True`, prefix each printout line with the code filename and line
    number where the configuration event occurred. Default is `True`.
prefix : `str`, optional
    A prefix for to add to each printout line. This prefix occurs first,
    even before any source line. The default is an empty string.
verbose : `bool`, optional
    Default is `False`.
