[docs]def save(obj, filename=None, resources=None, title=None, state=None, **kwargs):
''' Save an HTML file with the data for the current document.
Will fall back to the default output state (or an explicitly provided
:class:`State` object) for ``filename``, ``resources``, or ``title`` if they
are not provided. If the filename is not given and not provided via output state,
it is derived from the script name (e.g. ``/foo/myplot.py`` will create
``/foo/myplot.html``)
Args:
obj (LayoutDOM object) : a Layout (Row/Column), Plot or Widget object to display
filename (str, optional) : filename to save document under (default: None)
If None, use the default state configuration.
resources (Resources, optional) : A Resources config to use (default: None)
If None, use the default state configuration, if there is one.
otherwise use ``resources.INLINE``.
title (str, optional) : a title for the HTML document (default: None)
If None, use the default state title value, if there is one.
Otherwise, use "Bokeh Plot"
state (State, optional) :
A :class:`State` object. If None, then the current default
implicit state is used. (default: None).
Returns:
str: the filename where the HTML file is saved.
