There is no obvious way to get what is printed by gnubg.command() in a python variable. gnubg.command is really a kind of minimal catch-all to run whatever CLI command that has not equivalent in the python API.

It would make sense for it to do this, or to have a gnubg.show() function retunrning a string, but neither is currently available.

What you could do is to start with gnubg.board() and compute the pip counts, percentage difference and cube decision according to the 8/9/12 rule yourself.

I'm trying to create a GNUbg Python script that takes the 8912 theory output of a specific move and then add to the comments section of that move. The reason I need it in the comments is that I am trying to make the 8912 output show on the HTML export as an Annotation.

I have tried the following code:
s = gnubg.command('show 8912')
gnubg.command('annotate move comment "' + s + '"')

But it does not work because gnubg.command does not return anything. The output is written to the screen. I tried to capture stdout using regular Python stdout code, but it didn't work, so I assume because the script is running inside gnubg itself? I am launching the script using 'load python script_name.py' at the gnubg command prompt.

Any help would be appreciated on how to capture output from gnubg.command().

Thank you.
