The
file defines various settings to be used by the
editline(3)
library.
The format of each line is:
[prog:]command [arg [...]]
command
is one of the
editline(3)
builtin commands.
Refer to
Sx BUILTIN COMMANDS
for more information.
prog
is the program name string that a program defines when it calls
el_init3
to set up
editline(3),
which is usually
argv[0]command
will be executed for any program which matches
prog
prog
may also be a
regex(3)
style
regular expression, in which case
command
will be executed for any program that matches the regular expression.
If
prog
is absent,
command
is executed for all programs.
BUILTIN COMMANDS
The
editline
library has some builtin commands, which affect the way
that the line editing and history functions operate.
These are based on similar named builtins present in the
tcsh(1)
shell.
Without options, list all bound keys, and the editor command to which
each is bound.
If
key
is supplied, show the bindings for
key
If
key command
is supplied, bind
command
to
key
Options include:
-e
Bind all keys to the standard GNU Emacs-like bindings.
-v
Bind all keys to the standard
vi(1)Ns-like
bindings.
-a
List or change key bindings in the
vi(1)
mode alternate (command mode) key map.
-k
key
is interpreted as a symbolic arrow key name, which may be one of
`up'
`down'
`left'
or
`right'
-l
List all editor commands and a short description of each.
-r
Remove a key's binding.
-s
command
is taken as a literal string and treated as terminal input when
key
is typed.
Bound keys in
command
are themselves reinterpreted, and this continues for ten levels of
interpretation.
command
may be one of the commands documented in
Sx EDITOR COMMANDS
below, or another key.
key
and
command
can contain control characters of the form
`^ character
'
(e.g.
`^A )'
and the following backslashed escape sequences:
\a
Bell
\b
Backspace
\e
Escape
\f
Formfeed
\n
Newline
\r
Carriage return
\t
Horizontal tab
\v
Vertical tab
\ nnn
The ASCII character corresponding to the octal number
nnn
`\'
nullifies the special meaning of the following character,
if it has any, notably
`\'
and
`^'
echotc
[-sv
]
arg...
Exercise terminal capabilities given in
arg ...
If
arg
is
`baud'
`cols'
`lines'
`rows'
`meta or'
`tabs'
the value of that capability is printed, with
``yes''
or
``no''
indicating that the terminal does or does not have that capability.
-s
returns an empty string for non-existent capabilities, rather than
causing an error.
-v
causes messages to be verbose.
edit [on | off
]
Enable or disable the
editline
functionality in a program.
history list | size n | unique n
The
list
command lists all entries in the history.
The
size
command sets the history size to
n
entries.
The
unique
command controls if history should keep duplicate entries.
If
n
is non zero, only keep unique history entries.
If
n
is zero, then keep all entries (the default).
telltc
List the values of all the terminal capabilities (see
termcap(5)).
settc cap val
Set the terminal capability
cap
to
val
as defined in
termcap(5).
No sanity checking is done.
Control which tty modes that
will not allow the user to change.
-d
-q
or
-x
tells
setty
to act on the
`edit'
`quote'
or
`execute'
set of tty modes respectively; defaulting to
-x
Without other arguments,
setty
lists the modes in the chosen set which are fixed on
(`+mode'
)
or off
(`-mode'
)
-a
lists all tty modes in the chosen set regardless of the setting.
With
+mode-mode
or
mode
fixes
mode
on or off or removes control of
mode
in the chosen set.
Setty
can also be used to set tty characters to particular values using
char=value
If
value
is empty
then the character is set to
_POSIX_VDISABLE
