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 +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. +.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_RPROMPT , Fa "char *(*f)(EditLine *)" +Define right side prompt printing function as +.Fa f , +which is to return a string that contains the prompt. +.It Dv EL_TERMINAL , Fa "const char *type" +Define terminal type of the tty to be +.Fa type , +or to +.Ev TERM +if +.Fa type +is +.Dv NULL . +.It Dv EL_EDITOR , Fa "const char *mode" +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. +.It Dv EL_BIND , Xo +.Fa "const char *" , +.Fa "..." , +.Dv NULL +.Xc +Perform the +.Ic bind +builtin command. +Refer to +.Xr editrc 5 +for more information. +.It Dv EL_ECHOTC , Xo +.Fa "const char *" , +.Fa "..." , +.Dv NULL +.Xc +Perform the +.Ic echotc +builtin command. +Refer to +.Xr editrc 5 +for more information. +.It Dv EL_SETTC , Xo +.Fa "const char *" , +.Fa "..." , +.Dv NULL +.Xc +Perform the +.Ic settc +builtin command. +Refer to +.Xr editrc 5 +for more information. +.It Dv EL_SETTY , Xo +.Fa "const char *" , +.Fa "..." , +.Dv NULL +.Xc +Perform the +.Ic setty +builtin command. +Refer to +.Xr editrc 5 +for more information. +.It Dv EL_TELLTC , Xo +.Fa "const char *" , +.Fa "..." , +.Dv NULL +.Xc +Perform the +.Ic telltc +builtin command. +Refer to +.Xr editrc 5 +for more information. +.It Dv EL_ADDFN , Xo +.Fa "const char *name" , +.Fa "const char *help" , +.Fa "unsigned char (*func)(EditLine *e, int ch) +.Xc +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 +EOF was entered. +.It Dv CC_ARGHACK +Expecting further command input as arguments, do nothing visually. +.It Dv CC_REFRESH +Refresh display. +.It Dv CC_REFRESH_BEEP +Refresh display, and beep. +.It Dv CC_CURSOR +Cursor moved, so update and perform +.Dv CC_REFRESH. +.It Dv CC_REDISPLAY +Redisplay entire input line. +This is useful if a key binding outputs extra information. +.It Dv CC_ERROR +An error occurred. +Beep, and flush tty. +.It Dv CC_FATAL +Fatal error, reset

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 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. +.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 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

Fl v +Bind all keys to the standard +.Xr vi 1 -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

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 +List the history. +.It
