NAME

     editrc — configuration file for editline library

SYNOPSIS

     editrc

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.
