[Discuss-gnuradio] How to put $HOME in Variable Config?

[Lapo Pieri]

Hi List,
I need to specify a path for the Variable Config block of gnuradio-companion
as "$HOME/.mdr/freq_f0.dat" so I specified "$HOME/.mdr/freq_f0.dat" in
"Config file" field of Variable Config block.
In generated python file appears:

    self._freq_config.read('$HOME/.mdr/freq_f0.dat')

that cannot works...

I usually do it in python using somethings like:

    env_home=os.environ["HOME"]
    cfg_dir=env_home+"/.mdr/"

and pass "cfg_dir+<filename>" where needed

Could you point me out how to do this in gnuradio-companion?

Many thanks!

Lapo
