Hi,

I’m trying to use the function get\_tags\_in\_window in an implementation  
of a  
gr.sync\_block in python. Apparently, this function is not visible to  
SWIG.

Does anyone have a hint on what I can do?

PS: get\_tags\_in\_range worked.

Thanks,

Hi Maiconkist,

this is a speciality of how SWIG wrapping of these core components is  
done in GNU Radio. get\_tags\_in\_window is brand new, if I’m not mistaken,  
and the author might simply have forgotten to add it to the wrapped  
functions.

You should just have a look at  
gnuradio-runtime/include/gnuradio/block\_gateway.h, and add the function  
missing.[1]

Anyway, since modifying GNU Radio might be more complicated than working  
around, get\_tags\_in\_window is nothing more than a get\_tags\_in\_range with  
the start and end added to nitems\_read(0).

Greetings,

[1] I’m quite busy right now, but if you could do that, push the changes  
to a github repo and open up a pull request, that would be awesome, I  
guess.
