- A kind of FAQ for libreadline on Debian GNU/{Linux,Hurd}
- --------------------------------------------------------
-
- 0. symlinked directory completion behavior
-
- Starting with readline-4.2a, completion on symlinks that point
- to directories does not append the slash. To restore the behaviour
- found in readline-4.2, add to /etc/inputrc or ~/.inputrc:
-
- set mark-symlinked-directories on
-
- 1. reenable the paren matching feature in readline-4.1
-
- Add to /etc/inputrc or ~/.inputrc:
-
- set blink-matching-paren on
-
- 2. key bindings for ESC
-
- Consider the following .inputrc:
-
- set editing-mode vi
-
- keymap vi
- "\M-[D": backward-char
- "\M-[C": forward-char
- "\M-[A": previous-history
- "\M-[B": next-history
-
- And, just to be certain, set -o reports that vi is on.
-
- However, ESC k does not send me to the previous line.
-
- I'm guessing that this is a conflict between bash's concept of a meta
- keymap and its concept of vi's command-mode character -- which is to
- say that its data structures don't properly reflect its implementation.
-
- Note that if I remove the meta prefix, leaving lines like:
- "[A": previous-history
-
- That vi command mode keys work fine, and I can use the arrow keys in vi
- mode, *provided I'm already in command mode already*. In other words,
- bash is doing something wrong here such that it doesn't see the escape
- character at the begining of the key sequence even when in vi insert mode.
-
- Comment from the upstream author: "This guy destroyed the key binding for
- ESC, which effectively disabled vi command mode. It's not as simple as he
- paints it to be -- the binding for ESC in the vi insertion keymap *must*
- be a function because of the other things needed when switching
- from insert mode to command mode.
-
- If he wants to change something in vi's command mode, he needs
- to use `set keymap vi-command' and enter key bindings without
- the \M- prefix (as he discovered)."
