Bring back readline capability?

[Paul Ivanov]

Hey everyone - 

I was mostly AFK as the prompt_toolkit stuff landed in IPython, but I keep coming across users who are bitten by various corner cases that I really think we should reconsider bringing back our original readline-based code. 

I've opened an issue where I link to a recent discussion on the Sage mailing list related to this as well as a few issue and sentiment from other users who have been affected.

https://github.com/ipython/ipython/issues/10364

This issue has been causing me to actually avoid IPython, so I'm willing to do the work to get this back in time for 6.0

Thanks Paul, I don't have strong feelings about bringing back readline
or not (fine with it). However should we fix those corner cases you
mention regardless?

I've +1 on the issue, it is likely to be more challenging than it might appear.

Hi folks,​

it would be great to hear from anyone who may have input one way or another on this issue, especially if your use case isn't already listed by Paul's summary (and if so, please provide specific details).  We'll look for a good solution and continue the discussion on the issue:

https://github.com/ipython/ipython/issues/10364

and the linked PR:

https://github.com/ipython/ipython/pull/10373

but feedback will be very valuable.

Cheers
