irb behaves strange in Ruby 2.6

Bug #15442: irb behaves strange in Ruby 2.6

Added by ana06 (Ana Maria Martinez Gomez) over 7 years ago. Updated about 7 years ago.

Assignee:

Target version:
-
ruby -v:
Ruby 2.6 (trunk)
Backport:
2.4: UNKNOWN, 2.5: UNKNOWN
[ruby-core:90633]

Description

When trying to press the UP, DOWN, LEFT and RIGHT keys in Ruby 2.6 strange characters are printed instead of moving (or showing the last executed instruction). This works properly for me in Ruby 2.5.

irb(main):004:0> ^[[A^[[A^[[B^[[C^[[D

The keyboard line editing behaviors are based on GNU Readline. Please install GNU Readline before you build Ruby.

For example, if you're using Ubuntu 18.10, run sudo apt install libreadline-dev and re-build Ruby.

You can check the availability of readline by this command line:

ruby -rreadline -ep

I think I didn't have current trunk version. It seems to work no. Sorry
