Technical Background of Interactive CLI of Ruby 2.7
summary
Reline is a pure Ruby GNU Readline replacement that lands in Ruby 2.7 when system Readline is absent and powers a new multiline IRB, implemented as three layers: select(2)/kbhit getwch keyboard input layer, Emacs and Vi line‑editing bindings ported from GNU Readline, and string construction by environment encoding handling grapheme clusters not just codepoints. Reline is released to rubygems (reline 0.0.6) and IRB 1.1.0 ships but early releases contain Unicode and editing bugs that are actively fixed.
