Hi,
I found some aspects of readline documentation that seem inconsistent to
me and I wanted to share them.
1. The difference between backward-kill-line and unix-line-discard
readline commands.
Documentation states:
backward-kill-line (C-x Rubout)
Kill backward to the beginning of the line.
unix-line-discard (C-u)
Kill backward from point to the beginning of the
line. The
killed text is saved on the kill-ring.
In both cases they kill from the point and killed text is saved in the
kill-ring.
2. Default key sequences vs. emacs key bindings [the default].
It is confusing to me that there are two defaults. Firstly, it can be read:
EDITING COMMANDS
The following is a list of the names of the commands and
the default
key sequences to which they are bound. Command names without
an accom‐
panying key sequence are unbound by default.
On the other hand, emacs editing command are default:
readline offers editing capabilities while the user is entering the
line. By default, the line editing commands are similar to
those of
emacs. A vi-style line editing interface is also available.
An explicit list of emacs commands is maintained and commands do not
always coincide (both being valid defaults in practice). For example,
instead of C-x Rubout for backward-kill-line, emacs has
"C-XC-?" backward-kill-line
3. Key-bindings in the emacs/vi list are written with capital letters
(C-A), but not in the section with the description (C-a).
Best regards,
Daniel
