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 +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

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 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 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

Xo +.Op Fl sv +.Ar arg +.Ar ... +.Xc +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
