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 set up .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. .Pp If .Ar prog is absent, .Ar command is executed for all programs. .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 Oo Fl aeklrsv Oc Op Ar key Op Ar command Without options and arguments, list all bound keys and macros, and the editor command or input string to which each one is bound. If only .Ar key is supplied, show the binding for that key or macro. If .Ar key command is supplied, bind the editor .Ar command to that key or macro. .Pp The options are as follows: .Bl -tag -width 4n .It Fl a List or change key bindings in the .Xr vi 1 mode alternate (command mode) key map. .It Fl e Bind all keys to the standard GNU Emacs-like bindings. .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 the binding of the key or macro .Ar key . .It Fl s Define a keyboard macro rather than a key binding or command macro: .Ar command is taken as a literal string and appended to the input queue whenever .Ar key is typed. Bound keys and macros in .Ar command are themselves reinterpreted, and this continues for ten levels of interpretation. .It Fl v Bind all keys to the standard .Xr vi 1 Ns -like bindings. .El .Pp The .Xr editline 7 manual documents all editor commands and contains more information about macros and the input queue. .Pp .Ar key and .Ar command can contain control characters of the form .Sm off .Sq No ^ Ar character .Sm on .Po e.g.\& .Sq ^A .Pc , and the following backslashed escape sequences: .Pp .Bl -tag -compact -offset indent -width 4n .It Ic \ea Bell .It Ic \eb Backspace .It Ic \ee Escape .It Ic \ef Formfeed .It Ic \en Newline .It Ic \er Carriage return .It Ic \et Horizontal tab .It Ic \ev Vertical tab .Sm off .It Sy \e Ar nnn .Sm on The ASCII character corresponding to the octal number .Ar nnn . .El .Pp .Sq \e nullifies the special meaning of the following character, if it has any, notably .Sq \e and .Sq ^ . .It Ic echotc Oo Fl sv Oc Ar arg Ar ... Exercise terminal capabilities given in .Ar arg ... . If .Ar arg is .Sq baud , .Sq cols , .Sq lines , .Sq rows , .Sq meta , or .Sq tabs , the value of that capability is printed, with .Dq yes or .Dq no indicating that the terminal does or does not have that capability. .Pp .Fl s returns an empty string for non-existent capabilities, rather than causing an error. .Fl v causes messages to be verbose. .It Ic edit Op Li on | Li off Enable or disable the .Nm editline functionality in a program. .It Ic history Ar list | Ar size Dv n | Ar unique Dv n The .Ar list command lists all entries in the history. The .Ar size command sets the history size to .Dv n entries. The .Ar unique command controls if history should keep duplicate entries. If .Dv n is non zero, only keep unique history entries. If .Dv n is zero, then keep all entries (the default). .It Ic settc Ar cap Ar val Set the terminal capability .Ar cap to .Ar val , as defined in .Xr termcap 5 . No sanity checking is done. .It Ic setty Oo Fl a Oc Oo Fl d Oc Oo Fl q Oc Oo Fl x Oc Oo Ar +mode Oc \ Oo Ar -mode Oc Oo Ar mode Oc Oo Ar char=c Oc Control which tty modes that .Nm won't allow the user to change. .Fl d , .Fl q or .Fl x tells .Ic setty to act on the .Sq edit , .Sq quote or .Sq execute set of tty modes respectively; defaulting to .Fl x . .Pp Without other arguments, .Ic setty lists the modes in the chosen set which are fixed on .Po .Sq +mode .Pc or off .Po .Sq -mode .Pc . .Fl a lists all tty modes in the chosen set regardless of the setting. With .Ar +mode , .Ar -mode or .Ar mode , fixes .Ar mode on or off or removes control of .Ar mode in the chosen set. .Pp .Ic Setty can also be used to set tty characters to particular values using .Ar char=value . If .Ar value is empty then the character is set to .Dv _POSIX_VDISABLE . .It Ic telltc List the values of all the terminal capabilities (see .Xr termcap 5 ) . .El .Sh ENVIRONMENT .Bl -tag -width "~/.editrcXXX" .It Ev EDITRC Names the default configuration file for the .Xr editline 3 library. .El .Sh FILES .Bl -tag -width "~/.editrcXXX" .It Pa ~/.editrc Last resort, if no other file is specified, user configuration file for the .Xr editline 3 library. .El .Sh SEE ALSO .Xr editline 3 , .Xr regex 3 , .Xr termcap 5 , .Xr editline 7 .Sh AUTHORS .An -nosplit The .Nm editline library was written by .An Christos Zoulas , and this manual was written by .An Luke Mewburn , with some sections inspired by .Xr tcsh 1 .
