Hello, I have found two or three bugs regarding how Readline suggest file completions.
Config 1 (applies to bugs 1, 2, and 3): readline version: 8.2.013-1 (as per pacman -Q on Arch) Config 2 (applies to bugs 1 and 3): readline version: readline-common 8.2-1.3 (as per dpkg -l on Debian Stable) libreadline version: libreadline8:amd64 8.2-1.3 (as per dpkg -l on Debian Stable) Description and repeat instructions: Bug 1: `colored-completion-prefix' highlights the first character, even when not typed if `completion-prefix-display-length' is set to >= 1. Also, typed letters are not highlighted at all if the whole word suggestion matches the typed file and there is more than one suggestion. [chars] indicates highlighted character(s) $ bind 'set colored-completion-prefix on' $ bind 'set completion-prefix-display-length 10' $ ls /<tab><tab> [b]in/ [b]oot/ [d]ev/ [e]tc/ (output omitted) In this next example, /etc/group is not highlighted even when typed. $ ls /etc/group<tab><tab> group [group]- $ bind 'set completion-prefix-display-length 0' Now everything works fine ======================================================================== Bug 2: Readline sugguests directories with two consecutive consecutive slashes // when a matching glob is used on the command line. Happens even when all settings are turned off. $ ls /*/<tab><tab> # try /???/ as well bin// boot// dev// etc// Feature Request: I think it would be neat if Readline worked and highlighted glob characters. $ ls /??? Readline would then highlight [etc]/ and [hom]e/ ======================================================================== Bug 3: Underscores appear instead of ellipsis for `completion-prefix-display-length' if the readline suggestion ellipsis are before a period . This may be undocumented intended behavior, I am not sure. If this is a bug it may be worth keeping, but perhaps an update to the readline(3) man page is in order. $ bind 'set completion-prefix-display-length 3' $ touch test.txt testnodot $ ls test<tab><tab> ...nodot ___.txt Thank you for your time and for reading, Freddie Abell
