Where can I find gr and audio module?

Hello,

I am going through the GNUradio tutorials (the website ones and the ones

written by Dawei Shen). The codes in the tutorials import gr and audio
packages from gnuradio. I am searching for these modules (especially the gr
one) in http://gnuradio.org/doc/doxygen/group__usrp.html. I see a lot of
classes that are related with gr, e.g., gr_noise_source & other ones.
However, I did not find any module whose title is exactly ‘gr’.

In tutorial 6, Dawei Shen describes a few lines of the contents of gr. He
also mentions about a sub-folder titled ‘gr’ inside the ‘gnuradio’ folder
(/usr/local/python2.4/site-packages/gnuradio/gr/basic_flow_graph.py). I am
currently using gnuradio-3.3. I see subfolders titled gr-audio-jack,
gr-paper, etc. in the gnuradio folder. However, I don’t see a folder whose
title is exactly ‘gr’.

How can I see the contents of gr? I know that I am probably asking a
too
elementary question due to my limited knowledge in linux & OOP.

Thanks in advance!

Nazmul,
You mean like looking at the gr module to see what blocks are included
inside? You can just use “dir(gr)”, or something like:

for g in dir(gr):
print g

OR:

print “\n”.join([g for g in dir(gr)])

Both of these will print all available objects in gr, one per line.

Also, you can use iPython as a command-line Python interpreter shell. In
iPython, typing “dir(gr)” will print the objects as a column, too.
