Chapter 29. Command Line Editing
295
Variable names and values, where appropriate, are recognized without regard to case.
A great deal of run-time behavior is changeable with the following variables.
bell-style
Controls what happens when Readline wants to ring the terminal bell. If set to
none
, Read-
line never rings the bell. If set to
visible
, Readline uses a visible bell if one is available.
If set to
audible
(the default), Readline attempts to ring the terminal’s bell.
comment-begin
The string to insert at the beginning of the line when the
insert-comment
command is
executed. The default value is
"#"
.
completion-ignore-case
If set to
on
, Readline performs filename matching and completion in a case-insensitive
fashion. The default value is
off
.
completion-query-items
The number of possible completions that determines when the user is asked whether he
wants to see the list of possibilities. If the number of possible completions is greater than
this value, Readline will ask the user whether or not he wishes to view them; otherwise,
they are simply listed. This variable must be set to an integer value greater than or equal to
0. The default limit is
100
.
convert-meta
If set to
on
, Readline will convert characters with the eighth bit set to an ascii key sequence
by stripping the eighth bit and prefixing an [ESC] character, converting them to a meta-
prefixed key sequence. The default value is
on
.
disable-completion
If set to
On
, Readline will inhibit word completion. Completion characters will be inserted
into the line as if they had been mapped to
self-insert
. The default is
off
.
editing-mode
The
editing-mode
variable controls which default set of key bindings is used. By default,
Readline starts up in Emacs editing mode, where the keystrokes are most similar to Emacs.
This variable can be set to either
emacs
or
vi
.
enable-keypad
When set to
on
, Readline will try to enable the application keypad when it is called. Some
systems need this to enable the arrow keys. The default is
off
.
expand-tilde
If set to
on
, tilde expansion is performed when Readline attempts word completion. The
default is
off
.
If set to
on
, the history code attempts to place point at the same location on each history line
retrived with
previous-history
or
next-history
.
horizontal-scroll-mode
This variable can be set to either
on
or
off
. Setting it to
on
means that the text of the lines
being edited will scroll horizontally on a single screen line when they are longer than the
