undefined method `get_screen_size' for Readline:Module about tty-screen HOT 6 CLOSED

That's interesting. I have no answer to that apart from the referenced commit which will ensure that if the method is not present it will simply move on to another check. One thing that may also be the reason for intermittent check of readline is that the io/console is checked first and if it suceeds it never checks readline. So it maybe the failure of loading the io/console that forces the readline check but that's just unconfirmed suspicion.

Once I've done all the checks on jruby and windows I will release a patch version. I'm also planning to release a new version this coming weekend that simplifies the TTY::Screen and removes the need for instatiation and provides just simple module. Also I may add new checks including calling ioctl etc... Who would imagine that getting terminal size is such a hard task!

Hey Kimmo,

Thanks for reporting this. I've had a quick look and I think this is due to the fact that Ruby readline is a wrapper over native OS readline implantation which varies across different systems. For example the get_screen_size doesn't exist on windows.

I hope I will find some time today, I'm going after work to repetitively pick up and put down some heavy items but should have enough time to release a fix.

I still need to perform few tests on Windows box and jruby to make sure all the methods for inferring size work as expected.

The strange thing is that @matti says it's occasional and doesn't happen 100% of the time. Also from the path I assume it's running on a mac.

yep, mac os sierra running in terraform local-exec.

Released v0.5.1 which should automatically be pulled through by all the parent tty dependencies that use it. I've checked all calls on Debian/Mac/Windows to fix pretty much all issues. So I hope you won't have any issues with the latest release. Can you please upgrade and let me know?
