+.Sh DESCRIPTION
+The
+.Nm
+library provides generic line editing, history and tokenization functions,
+similar to those found in
+.Xr sh 1 .
+.Pp
+These functions are available in the
+.Nm libedit
+library (which needs the
+.Nm libtermcap
+library).
+Programs should be linked with
+.Fl ledit ltermcap .
+.Sh LINE EDITING FUNCTIONS
+The line editing functions use a common data structure,
+.Fa EditLine ,
+which is created by
+.Fn el_init
+or
+.Fn el_init_fd
+and freed by
+.Fn el_end .
+.Pp
+The wide-character functions behave the same way as their narrow
+counterparts.
+.Pp
+The following functions are available:
+.Bl -tag -width 4n
+.It Fn el_init
+Initialise the line editor, and return a data structure
+to be used by all other line editing functions.
+.Fa prog
+is the name of the invoking program, used when reading the
+.Xr editrc 5
+file to determine which settings to use.
+.Fa fin ,
+.Fa fout
+and
+.Fa ferr
+are the input, output, and error streams (respectively) to use.
+In this documentation, references to
+.Dq the tty
+are actually to this input/output stream combination.
+.It Fn el_init_fd
+Like
+.Fn el_init
+but allows specifying file descriptors for the
+.Xr stdio 3
+corresponding streams, in case those were created with
+.Xr funopen 3 .
+.It Fn el_end
+Clean up and finish with
+.Fa e ,
+assumed to have been created with
+.Fn el_init
+or
+.Fn el_init_fd .
+.It Fn el_reset
+Reset the tty and the parser.
+This should be called after an error which may have upset the tty's
+state.
+.It Fn el_gets
+Read a line from the tty.
+.Fa count
+is modified to contain the number of characters read.
+Returns the line read if successful, or
+.Dv NULL
+if no characters were read or if an error occurred.
+If an error occurred,
+.Fa count
+is set to \-1 and
+.Dv errno
+contains the error code that caused it.
+The return value may not remain valid across calls to
+.Fn el_gets
+and must be copied if the data is to be retained.
+.It Fn el_getc
+Read a character from the tty.
+.Fa ch
+is modified to contain the character read.
+Returns the number of characters read if successful, \-1 otherwise,
+in which case
+.Dv errno
+can be inspected for the cause.
+.It Fn el_push
+Pushes
+.Fa str
+back onto the input stream.
+This is used by the macro expansion mechanism.
+Refer to the description of
+.Ic bind
+.Fl s
+in
+.Xr editrc 5
+for more information.
+.It Fn el_parse
+Parses the
+.Fa argv
+array (which is
+.Fa argc
+elements in size)
+to execute builtin
+.Nm
+commands.
+If the command is prefixed with
+.Dq prog :
+then
+.Fn el_parse
+will only execute the command if
+.Dq prog
+matches the
+.Fa prog
+argument supplied to
+.Fn el_init .
+The return value is
+\-1 if the command is unknown,
+0 if there was no error or
+.Dq prog
+didn't match, or
+1 if the command returned an error.
+Refer to
+.Xr editrc 5
+for more information.
+.It Fn el_set
+Set
+.Nm
+parameters.
+.Fa op
+determines which parameter to set, and each operation has its
+own parameter list.
+.Pp
+The following values for
+.Fa op
+are supported, along with the required argument list:
+.Bl -tag -width 4n
+.It Dv EL_PROMPT , Fa "char *(*f)(EditLine *)"
+Define prompt printing function as
+.Fa f ,
+which is to return a string that contains the prompt.
+.It Dv EL_PROMPT_ESC , Fa "char *(*f)(EditLine *)" , Fa "char c"
+Same as
+.Dv EL_PROMPT ,
+but the
+.Fa c
+argument indicates the start/stop literal prompt character.
+.Pp
+If a start/stop literal character is found in the prompt, the
+character itself
+is not printed, but characters after it are printed directly to the
+terminal without affecting the state of the current line.
+A subsequent second start/stop literal character ends this behavior.
+This is typically used to embed literal escape sequences that change the
+color/style of the terminal in the prompt.
+.Dv 0
+unsets it.
+.It Dv EL_REFRESH
+Re-display the current line on the next terminal line.
+.It Dv EL_RPROMPT , Fa "char *(*f)(EditLine *)"

+Set editing mode to
+.Fa mode ,
+which must be one of
+.Dq emacs
+or
+.Dq vi .
+.It Dv EL_SIGNAL , Fa "int flag"
+If
+.Fa flag
+is non-zero,
+.Nm
+will install its own signal handler for the following signals when
+reading command input:
+.Dv SIGCONT ,
+.Dv SIGHUP ,
+.Dv SIGINT ,
+.Dv SIGQUIT ,
+.Dv SIGSTOP ,
+.Dv SIGTERM ,
+.Dv SIGTSTP ,
+and
+.Dv SIGWINCH .
+Otherwise, the current signal handlers will be used.

+.Xr editrc 5
+for more information.
+.It Dv EL_ECHOTC , Fa "const char *" , Fa "..." , Dv NULL
+Perform the
+.Ic echotc
+builtin command.
+Refer to
+.Xr editrc 5
+for more information.
+.It Dv EL_SETTC , Fa "const char *" , Fa "..." , Dv NULL

+Fa "unsigned char (*func)(EditLine *e, int ch)"
+Add a user defined function,
+.Fn func ,
+referred to as
+.Fa name
+which is invoked when a key which is bound to
+.Fa name
+is entered.
+.Fa help
+is a description of
+.Fa name .
+At invocation time,
+.Fa ch
+is the key which caused the invocation.
+The return value of
+.Fn func
+should be one of:
+.Bl -tag -width "CC_REDISPLAY"
+.It Dv CC_NORM
+Add a normal character.
+.It Dv CC_NEWLINE
+End of line was entered.
+.It Dv CC_EOF

+At this time, it is the caller's responsibility to
+check this
+(using
+.Fn el_get )
+to determine if editing should be enabled or not.
+.It Dv EL_UNBUFFERED , Fa "int flag"
+If
+.Fa flag
+is zero,
+unbuffered mode is disabled (the default).
+In unbuffered mode,
+.Fn el_gets
+will return immediately after processing a single character.
+.It Dv EL_GETCFN , Fa "int (*f)(EditLine *, char *c)"
+Define the character reading function as
+.Fa f ,
+which is to return the number of characters read and store them in
+.Fa c .
+This function is called internally by
+.Fn el_gets

+.Sh NAME
+.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:
+.Dl [prog:]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 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 a Oc Oo Fl e Oc Oo Fl k Oc Oo Fl l Oc Oo Fl r Oc \
+Oo Fl s Oc Oo Fl v Oc Oo Ar key Oo Ar command Oc Oc
+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 command
+may be one of the commands documented in
+.Sx "EDITOR COMMANDS"
+below, or another key.
+.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 Ar ... .
+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 telltc
+List the values of all the terminal capabilities (see
+.Xr termcap 5 ) .
+.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 .
