Hi,
GNU Emacs wraps many readline-using programs, but disables readline in favor of its own line-editing commands. However, it would be great for Emacs to still be able to access readline completions on demand; then Emacs would display those completions to the user in Emacs-y ways. Right now there's no support in Emacs for accessing these completions, so completion in such programs is usually reimplemented inside Emacs in ad-hoc ways, or isn't supported at all. How should we access these completions if we want to disable line-editing? What do you recommend? Is there an existing mechanism which would be suitable for this? Or could a new feature for this be added to readline? Thanks! P.S. a few links to some limited prior discussion: https://debbugs.gnu.org/cgi/bugreport.cgi?bug=26661 https://github.com/szermatt/emacs-bash-completion/issues/45#issuecomment-1336463080
