[IPython-dev] notebook-like format for IPythonQt sessions.

Ok i'm going to paste a fragment of a document about this topic (that I've
not noticed until today)

*The frontend would store, for now, 5 types of data:

#. Input: this is python/ipython code to be executed.

#. Output (python): result of executing Inputs.

#. Standard output: from subprocesses.

#. Standard error: from subprocesses.

#. Text: arbitrary text. For now, we'll just store plain text and will defer
to the user on how to format it, though it should be valid reST if it is
later to be converted into html/pdf.

The non-text cells would be stored on-disk as follows::

.. input-cell::
:id: 1


.. output-cell::
:id: 1


.. input-cell::
:id: 2


.. stdout-cell::
:id: 2

a.py b.py

.. input-cell::
:id: 3


.. stderr-cell::
:id: 3

sh: askdfj: command not found*

This document clears some ideas, since the natural way for an IPython's
frontend (not only IPythonQt) to load data is rst in wich Python's and
IPython's documentation is written.

Still I want to resume this discussion because there are still some points
to clear such exporting and importing formats or if the saved session should
write also the output, etc.

I want to do this because I think it is not  so difficult to implement and
it should be part of the first release.

best regards.
