Ruby loses readline standard library when the system doesn't have libreadline during Ruby installation, At https://bugs.ruby-lang.org/issues/11084, @hsbt (Hiroshi SHIBATA) proposed pure Ruby implementation. But I think that rb-readline is not good for Ruby standard library and I described it at http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-core/86213. The important reason for it personally is that rb-readline doesn't have vi mode.

So I'm implementing Reline for a new standard library as GNU Readline and existing ext/readline compatible. I can maintain it.

I don't think that Reline should replace ext/readline fully, it's just for fallback. But it's important for Ruby.

Reline does not seem to support bracketed paste mode:

$ ruby -v ruby 2.7.0p0 (2019-12-25 revision 647ee6f091) [x86_64-darwin18] $ # has 2 lines of input pbpaste "abc" .upcase $ # readline respects bracketed paste mode, reads in both lines ruby -r readline -e 'p Readline.readline "> "' > "abc" .upcase "\"abc\"\n.upcase" $ # reline does not support bracketed paste mode, reads them in as 2 separate lines ruby -r reline -e '2.times { p Reline.readline "> " }' > "abc" "\"abc\"" > .upcase ".upcase" $ cat ~/.inputrc | sed '/^$/q' set enable-bracketed-paste on set blink-matching-paren on set colored-completion-prefix on set colored-stats on set keyseq-timeout 250 set show-all-if-ambiguous on set visible-stats on 

I also checked one of the other config options (blink-matching-paren) and it blinks with readline, but not reline. Makes me wonder if it isn't reading the ~/.inputrc file (it may be Mac specific).

Reporting it here as the Github project doesn't seem to have an issues section.
