+.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 libcurses
+library).
+Programs should be linked with
+.Fl ledit
+.Fl lcurses .
+.Sh LINE EDITING FUNCTIONS
+The line editing functions use a common data structure,
+.Fa EditLine ,
+which is created by
+.Fn el_init
+and freed by
+.Fn el_end .
+.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_end
+Clean up and finish with
+.Fa e ,
+assumed to have been created with
+.Fn el_init .
+.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.
+.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 *)"
+Define right side prompt printing function as
+.Fa f ,
+which is to return a string that contains the prompt.

+Define the right prompt printing function but with a literal escape character.
+.It Dv EL_TERMINAL , Fa "const char *type"

+.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.

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

+builtin command.
+Refer to
+.Xr editrc 5
+for more information.

+.Ic telltc
+builtin command.
+Refer to

+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 EL_EDITMODE , Fa "int flag"
+If
+.Fa flag
+is non-zero,
+editing is enabled (the default).
+Note that this is only an indication, and does not
+affect the operation of
+.Nm .
+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_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
+and
+.Fn el_getc .
+The builtin function can be set or restored with the special function
+name
+.Dq Dv EL_BUILTIN_GETCFN .
+.It Dv EL_CLIENTDATA , Fa "void *data"
+Register
+.Fa data

+return the start/stop literal prompt character in it.
+.It Dv EL_EDITOR , Fa "const char *"
+Return the name of the editor, which will be one of
+.Dq emacs
+or
+.Dq vi .
+.It Dv EL_GETTC , Fa "const char *name" , Fa "void *value"
+Return non-zero if
+.Fa name
