'''This Python Open Document Renderer (PodRenderer) loads a document
template (p_template) which is an ODT or ODS file with some elements
written in Python. Based on this template and some Python objects
defined in p_context, the renderer generates an ODT file (p_result)
that instantiates the p_template and fills it with objects from the
p_context.
- If p_result does not end with .odt or .ods, the Renderer will call
LibreOffice to perform a conversion. If p_forceOoCall is True, even
if p_result ends with .odt, LibreOffice will be called, not for
performing a conversion, but for updating some elements like indexes
(table of contents, etc) and sections containing links to external
files (which is the case, for example, if you use the default
function "document").
- If the Python interpreter which runs the current script is not
UNO-enabled, this script will run, in another process, a UNO-enabled
Python interpreter (whose path is p_pythonWithUnoPath) which will
call LibreOffice. In both cases, we will try to connect to
LibreOffice in server mode on port p_ooPort.
- If you plan to make "XHTML to OpenDocument" conversions, you may
specify a styles mapping in p_stylesMapping.
- If you specify a function in p_finalizeFunction, this function will
be called by the renderer before re-zipping the ODT/S result. This
way, you can still perform some actions on the content of the ODT/S
file before it is zipped and potentially converted. This function
must accept one arg: the absolute path to the temporary folder
containing the un-zipped content of the ODT/S result.
- If you set p_overwriteExisting to True, the renderer will overwrite
the result file. Else, an exception will be thrown if the result file
already exists.
- If p_raiseOnError is False (the default value), any error encountered
during the generation of the result file will be dumped into it, as
a Python traceback within a note. Else, the error will be raised.
- p_imageResolver allows POD to retrieve images, from "img" tags within
XHTML content. Indeed, POD may not be able (ie, may not have the
permission to) perform a HTTP GET on those images. Currently, the
resolver can only be a Zope application object.
