It's possible, just embed FPC with the python "embedded" in OpenOffice.
During holydays I made successfully this test (on windows) and I am
still investigating on the details.
Sorry but by now I don't have documentation, work is in progress, if
someone is interested (and this thread shows how few people is
interested in this matter) I can give further details.
Can you give further details?
ok, I try to give a brief overview, here I talk of FPC but read that as
FPC/Lazarus, please:
look at the Python Documentation: Extending and Embedding
(http://docs.python.org/ext/ext.html)
This chapter explains the ways to use python with other applications, it
is C/C++ based but it is simple to translate all that in Pascal.
Here you can see the concepts of Extending python with C/C++/FPC and
Embedding python in C/C++/FPC.
With this in mind you have not to port Python for Delphi to Lazarus, you
can simply build a suite of (simple) units that make up the interface
with the pythonxx.dll or pythonxx.so libraries, and this is possible
respecting the multiplatform requirements of FPC.
Now, since you can easily launch python scripts or modules from an
application compiled with FPC it is also possible to bind this
application with the pythonxx.dll that OpenOffice installs with its
binaries. This is an ordinary python distribution integrated with
modules that interface python with the OO APIs.
Now you need to look at PyUno documentation
(http://udk.openoffice.org/python/python-bridge.html).
Here you can see how to use Python and the Python-UNO bridge to issue
commands to OpenOffice.
With FPC you can only excecute the python Uno Bridge outside of the
OpenOffice process, this is a bit slow, but it is enough to launch from
FPC a simple helloworld.py that opens an OOWriter document and writes in
the document the usual "HelloWorld!" string (I tested this on Windows,
and I have to test if it really works also on Linux).
(note: Issuing commands to OpenOffice can be easily done with Delphi,
this is explained in the OpenOffice SDK, but it uses the Uno OLE
automation bridge. Since OLE and COM is not available in other
platforms, FPC doesn't support them, so, this approach is not available
for it)
From here there is a lot of work and experimentation to do, since it is
not enough to call python scripts to issue commands, but it is essential
to exchange data from FPC<->Python<->Office.
that's all by now, this is the idea. I'd like to hear some feedback
about that...
bye
