NAME¶
editrc —
configuration file for
editline library
SYNOPSIS¶
DESCRIPTION¶
The
editrc 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
BUILTIN
COMMANDS for more information.
prog is the program name string that a program defines
when it calls
el_init(3) 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.
The following builtin commands are available:
- bind
[-a]
[-e]
[-k]
[-l]
[-r]
[-s]
[-v]
[key
[command]]
- 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)-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
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.
- setty
[-a]
[-d]
[-q]
[-x]
[+mode]
[-mode]
[mode]
[char=c]
- Control which tty modes that editrc won't
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
.
