Date: Tue, 21 Jan 2020 08:23:10 +0000 (UTC) [thread overview]
Message-ID: <redmine.journal-83983.20200121082309.ec09fd31d075e165@ruby-lang.org> (raw)
In-Reply-To: redmine.issue-16510.20200115152201@ruby-lang.org
Issue #16510 has been updated by mame (Yusuke Endoh).
It works perfectly for me. I'm using GNOME Terminal (`GNOME Terminal 3.34.2 using VTE 0.58.2 +BIDI +GNUTLS`) in Ubuntu 19.10.

Bug #16510: irb crashes when hitting 'Home' or 'End' keys
https://bugs.ruby-lang.org/issues/16510#change-83983
* Author: packerbacker89 (Josh Johnson)
* Status: Open
* Priority: Normal
* Assignee:
* Target version:
* ruby -v: 2.7.0
* Backport: 2.5: UNKNOWN, 2.6: UNKNOWN, 2.7: UNKNOWN
----------------------------------------
There were similar bugs opened in the past few months, but they all appear to be closed.
System: Ruby 2.7.0, reline 0.1.2, irb 1.2.1
Open irb and hit the 'Home' or 'End' key on the keyboard. This should go to the beginning / end of the line. Instead, the console crashes and the following traceback is provided:

```
In addition, hitting the 'Insert', 'Page Up', and 'Page Down' keys result in odd characters shown in the console (such as "`^[[2~`"). This is only a minor issue compared to the console crash.
