Avoid using parenthesis enclosure macros (.Pq and .Po/.Pc) with plain text. Not only this slows down the mdoc(7) processing significantly, but it also has an undesired (in this case) effect of disabling hyphenation within the entire enclosed block.

.Nm editrc

.Nd configuration file for editline library
|
|
.Sh SYNOPSIS
|
|
.Nm
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
file defines various settings to be used by the
|
|
.Xr editline 3
|
|
library.
|
|
.Pp
|
|
The format of each line is either:
|
|
.Dl prog:command [arg [...]]
|
|
or
|
|
.Dl command [arg [...]]
|
|
.Pp
|
|
.Ar command
|
|
is one of the
|
|
.Xr editline 3
|
|
builtin commands.
|
|
Refer to
|
|
.Sx BUILTIN COMMANDS
|
|
for more information.
|
|
.Pp
|
|
.Ar prog
|
|
is the program name string that a program defines when it calls
|
|
.Xr el_init 3
|
|
to setup
|
|
.Xr editline 3 ,
|
|
which is usually
|
|
.Va argv[0] .
|
|
.Ar command
|
|
will be executed for any program which matches
|
|
.Ar prog .
|
|
.Pp
|
|
.Ar prog
|
|
may also be a
|
|
.Xr regex 3
|
|
style
|
|
regular expression, in which case
|
|
.Ar command
|
|
will be executed for any program that matches the regular expression.
|
|
.Sh BUILTIN COMMANDS
|
|
The
|
|
.Nm 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
|
|
.Xr tcsh 1
|
|
shell.
|
|
.Pp
|
|
The following builtin commands are available:
|
|
.Bl -tag -width 4n
|
|
.It Ic bind Xo
|
|
.Op Fl a
|
|
.Op Fl e
|
|
.Op Fl k
|
|
.Op Fl l
|
|
.Op Fl r
|
|
.Op Fl s
|
|
.Op Fl v
|
|
.Op Ar key Op Ar command
|
|
.Xc
|
|
Without options, list all bound keys, and the editor command to which
|
|
each is bound.
|
|
If
|
|
.Ar key
|
|
is supplied, show the bindings for
|
|
.Ar key .
|
|
If
|
|
.Ar key command
|
|
is supplied, bind
|
|
.Ar command
|
|
to
|
|
.Ar key .
|
|
Options include:
|
|
.Bl -tag -width 4n
|
|
.It Fl e
|
|
Bind all keys to the standard GNU Emacs-like bindings.
|
|
.It Fl v
|
|
Bind all keys to the standard
|
|
.Xr vi 1 Ns -like
|
|
bindings.
|
|
.It Fl a
|
|
List or change key bindings in the
|
|
.Xr vi 1
|
|
mode alternate (command mode) key map.
|
|
.It Fl k
|
|
.Ar key
|
|
is interpreted as a symbolic arrow key name, which may be one of
|
|
.Sq up ,
|
|
.Sq down ,
|
|
.Sq left
|
|
or
|
|
.Sq right .
|
|
.It Fl l
|
|
List all editor commands and a short description of each.
|
|
.It Fl r
|
|
Remove a key's binding.
|
|
.It Fl s
|
|
.Ar command
|
|
is taken as a literal string and treated as terminal input when
|
|
.Ar key
|
|
is typed.
|
|
Bound keys in
|
|
.Ar command
|
|
are themselves reinterpreted, and this continues for ten levels of
|
|
interpretation.
|
|
.El
|
|
.Pp
|
|
.Ar key
|
|
and
|
|
.Ar command
|
|
can contain control characters of the form
|
|
.Sm off
|
|
.Sq No ^ Ar character
|
|
.Sm on
|

indicating that the terminal does or does not have that capability.
|
