Subject: [ruby-core:117706] [Ruby master Bug#20454] IRB echoes excessive input in dumb terminal
Date: Thu, 25 Apr 2024 13:23:42 +0000 (UTC)	[thread overview]
Message-ID: <redmine.issue-20454.20240425132342.3546@ruby-lang.org> (raw)

Issue #20454 has been reported by zonuexe (Kenta USAMI).

----------------------------------------
Bug #20454: IRB echoes excessive input in dumb terminal
https://bugs.ruby-lang.org/issues/20454

* Author: zonuexe (Kenta USAMI)
* Status: Open
* ruby -v: ruby 3.3.1 (2024-04-23 revision c56cd86388) [arm64-darwin23]
* Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN
----------------------------------------
When IRB is started on a terminal with the environment variable TERM=dumb, excessive output is generated as shown below.

A simple terminal such as Emacs shell-mode or comint-mode is assumed, but it should be possible to reproduce the following with a rich terminal such as iTerm.

Type 1[RET], 12[RET], 123[RET] on your keyboard in this order.

% TERM=dumb irb
irb(main):001> 1
irb(main):001> 1=> 1
irb(main):002> 12
irb(main):002> 1irb(main):002> 12=> 12
irb(main):003> 123
irb(main):003> 1irb(main):003> 12irb(main):003> 123=> 123

As arton-san says, you can avoid the problem by not using ReadlineInputMethod.
