How to find the python description of gr.*

Hi,

I have read Eric’s “howto-write-a-signal-processing-block”, but I still
got
a question. Is there anyway I could find the python description of gr.*
modules(or functions). I browsed both
“gnuradio-core/src/python/gnuradio/gr”
and “python2.6/dist-packages/gnuradio/gr”, but I found nothing but
several
swig generated files.

In howto_square_ff example, the command “import howto” imports SWIG
generated “howto.py” module and applies “howto.square_ff” block. But in
“tx_voive.py” example, how could I find the description of
“gr.message_sink”
or “gr.msg_queue” in python? It seems there’s not such a file called
“gr.py”. I think “gr.*” are also generated by SWIG from their C++ Class,
but
I simply can’t find them. Appreciate your help.

Thank you!

Milo,

A large part of what shows up in Python are C++ classes that have been
interfaced to Python using SWIG to generate the glue code.

For things like gr.msg_queue, look in the C++ documentation for
gr_msg_queue.

Go here (or build the docs in your own directory):

http://gnuradio.org/doc/doxygen/index.html

Then click on Class List in the left hand column.
Then click on gr_msg_queue.

I see that. Thank you, Eric!
