Allow disabling verbosity #15

Open joshclimacell opened 6 years ago

joshclimacell commented 6 years ago

Hello,

The progress bar that gets emitted seems super useful for interactive analysis, but it is quite obtrusive when using richdem in non-interactive code, where the output gets jumbled all together. It'd be great if it could be disabled somehow, e.g. passing verbose=False.

r-barnes commented 5 years ago

This is a good idea. As a workaround until I have time to fix this, you could consider temporarily redirecting output:

https://stackoverflow.com/questions/6796492/temporarily-redirect-stdout-stderr

Does this help?

joshburkart commented 5 years ago

Ah, I tried that but it unfortunately didn't seem to work... I'm guessing contextlib.redirect_stdout only operates within Python and doesn't affect C++ stuff that writes directly to /dev/stdout? Anyways I can totally just eat the messages for now! 😁
