This works in Windows 8.. Thanks!

Thank you :) I'm using this for as part of it's tab completer function

I thought about using it for some stuff I'm writing it (thanks for providing it btw),
I forked it and added some 'caching' so it does not run all the tests again over and over:
It boosts it just a bit, 100k calls of the original get_terminal_size() took ~2.4 seconds, now it's just 1.8 seconds
(I'm not sure if that would be the pythonic way, I've just started learning python :'D)

Nice. License?

@maxbane I'm not sure how a license would work here, it was adapted from the script at which was adapted from

Hi jtriley I want to thank you for this script. I do a minor changes to it and using it for my own downloader script which is in github. I want to ask if it's ok for you.

Here is the script.

Great! I'll try to use this in my ffunenga/pipgh repo

Sweet, I'll be using a rendition of this in

For _get_terminal_size_tput, the subprocess calls should use subprocess.check_output, not subprocess.check_call.

The current code causes the size to be printed to the terminal, but the returned size will be (0,0) (that is, if tput successfully exits on each call).
