Issue #20052 has been updated by rubyFeedback (robert heiler). Interesting. It seems to do some additional buffering? If it behaves differently to readline then this may be a bug in behaviour; at the least if it is not a bug then the user may want to be able to get the readline-behaviour and perhaps an option to toggle between these two (though I think the Readline behaviour makes more sense, so I assume this may be a bug indeed.) ---------------------------------------- Bug #20052: reline behaves oddly with redirect (non tty) https://bugs.ruby-lang.org/issues/20052#change-105607 * Author: mtasaka (Mamoru Tasaka) * Status: Open * Priority: Normal * ruby -v: ruby 3.3.0dev (2023-12-09 master 1cbe114d1c) [x86_64-linux] * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- Forwarded from cucumber/aruba testsute issue https://github.com/cucumber/aruba/issues/910 Looks line reline behaves oddly with redirect (non tty) With `ruby 3.2.2 (2023-03-30 revision e51014f9c0) [x86_64-linux]` and `Readline`: ``` $ echo 'foo' | ruby -e 'require "readline"; puts Readline.readline(">")' > bar.log ; cat bar.log
