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 . +.Pp +The +.Nm +library respects the +.Ev LC_CTYPE +locale set by the application program and never uses +.Xr setlocale 3 +to change the locale. +The only locales supported are UTF-8 and the default C or POSIX locale. +If any other locale is set, behaviour is undefined. +.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 +Initialize the line editor, and return a data structure +to be used by all other line editing functions, or +.Dv NULL +on failure. +.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_wgetc +Read a wide character from the tty, respecting the current locale, +or from the input queue described in +.Xr editline 7 +if that is not empty, and store it in +.Fa wc . +If an invalid or incomplete character is found, it is discarded, +.Va errno +is set to +.Er EILSEQ , +and the next character is read and stored in +.Fa wc . +Returns 1 if a valid character was read, 0 on end of file, or \-1 on +.Xr read 2 +failure. +In the latter case, +.Va errno +is set to indicate the error. +.It Fn el_getc +Read a wide character as described for +.Fn el_wgetc +and return 0 on end of file or \-1 on failure. +If the wide character can be represented as a single-byte character, +convert it with +.Xr wctob 3 , +store the result in +.Fa ch , +and return 1; otherwise, set +.Va errno +to +.Er ERANGE +and return \-1. +In the C or POSIX locale, this simply reads a byte, but for any other +locale, including UTF-8, this is rarely useful. +.It Fn el_wpush +Push the wide character string +.Fa wcs +back onto the input queue described in +.Xr editline 7 . +If the queue overflows, for example due to a recursive macro, +or if an error occurs, for example because +.Fa wcs +is +.Dv NULL +or memory allocation fails, the function beeps at the user, +but does not report the problem to the caller. +.It Fn el_push +Use the current locale to convert the multibyte string +.Fa mbs +to a wide character string, and pass the result to +.Fn el_wpush . +.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. +Returns 0 on success, \-1 on failure. +.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. +Note that the literal escape character cannot be the last character in the +prompt, as the escape sequence is attached to the next character 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. +.It Dv EL_RPROMPT_ESC , Fa "char *(*f)(EditLine *)" , Fa "char c" +Define the right prompt printing function but with a literal escape character. +.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 , Fa "const char *" , Fa "..." , Dv NULL +Perform the +.Ic bind +builtin command. +Refer to +.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 +Perform the +.Ic settc +builtin command. +Refer to +.Xr editrc 5 +for more information. +.It Dv EL_SETTY , Fa "const char *" , Fa "..." , Dv NULL +Perform the +.Ic setty +builtin command. +Refer to +.Xr editrc 5 +for more information. +.It Dv EL_TELLTC , Fa "const char *" , Fa "..." , Dv NULL +Perform the +.Ic telltc +builtin command. +Refer to +.Xr editrc 5 +for more information. +.It Dv EL_ADDFN , Fa "const char *name" , Fa "const char *help" , \ +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 +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 tty to known state. +.El +.It Dv EL_HIST , Fa "History *(*func)(History *, int op, ...)" , \ +Fa "const char *ptr" +Defines which history function to use, which is usually +.Fn history . +.Fa ptr +should be the value returned by +.Fn history_init . +.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_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 "el_rfunc_t f" +Whenever reading a character, use the function +.Bd -ragged -offset indent -compact +.Ft int +.Fo f +.Fa "EditLine *e" +.Fa "wchar_t *wc" +.Fc +.Ed +which stores the character in +.Fa wc +and returns 1 on success, 0 on end of file, or \-1 on I/O or encoding +errors. +Functions internally using it include +.Fn el_wgets , +.Fn el_wgetc , +.Fn el_gets , +and +.Fn el_getc . +Initially, a builtin function is installed, and replacing it +is discouraged because writing such a function is very error prone. +The builtin function can be restored at any time by passing the +special value +.Dv EL_BUILTIN_GETCFN +instead of a function pointer. +.It Dv EL_CLIENTDATA , Fa "void *data" +Register +.Fa data +to be associated with this EditLine structure. +It can be retrieved with the corresponding +.Fn el_get +call. +.It Dv EL_SETFP , Fa "int fd" , Fa "FILE *fp" +Set the current +.Nm editline +file pointer for +.Dq input +.Fa fd += +.Dv 0 , +.Dq output +.Fa fd += +.Dv 1 , +or +.Dq error +.Fa fd += +.Dv 2 +from +.Fa fp . +.El +.It Fn el_get +Get +.Nm +parameters. +.Fa op +determines which parameter to retrieve into +.Fa result . +Returns 0 if successful, \-1 otherwise. +.Pp +The following values for +.Fa op +are supported, along with actual type of +.Fa result : +.Bl -tag -width 4n +.It Dv EL_PROMPT , Fa "char

+.Xr el_set 3 +was used to set +.Dv EL_EDITMODE +to 0, all input character bindings are disabled and all characters +typed are appended to the edit buffer. +In that case, the edit buffer is returned

em-universal-argument , +or +.Ic vi-zero . +When an argument is not provided, it defaults to 1. +For most editor commands, the effect of an argument is to repeatedly +execute the command that number of times. +.Pp +When talking about a character string from a left character to a +right character, the left character is included in the string, while +the right character is not included. +.Pp +If an editor command causes an error, the input character is discarded, +no action occurs, and the terminal bell is rung. +In case of a non-fatal error, the terminal bell is also rung, +but the editor command takes effect anyway. +.Pp +In the following list, the default key bindings are listed after +each editor command. +.Bl -tag -width 4n +.It Ic ed-argument-digit Pq vi command: 1 to 9; emacs:

ed-delete-next-char Pq vi command: x +Delete the character at the cursor position. +With an argument, delete that number of characters. +In emacs mode, it is an error if the cursor is at the end of the +edit buffer. +In vi mode, the last character in the edit buffer is deleted in +that case, and it is an error if the buffer is empty. +.It Ic ed-delete-prev-char Pq vi command: X, Ctrl-H, BS, Ctrl-?, DEL +Delete the character to the left of the cursor position. +With an argument, delete that number of characters. +It is an error if the cursor is at the beginning of the edit buffer. +.It Ic

the editor command +.Ic ed-sequence-lead-in , +.Nm +attempts to call a macro. +If the input character by itself forms the name of a macro, that +macro is executed. +Otherwise, additional input characters are read until the string +read forms the name of a macro, in which case that macro is executed, +or until the string read matches the beginning of none of the existing +macro names, in which case the string including the final, mismatching +character is discarded and the terminal bell is rung. +.Pp +There are two kinds of macros. +Command macros execute a single editor command. +Keyboard macros return a string of characters that is appended +as a new line to the +.Sx Input Queue . +.Pp +The following command macros are defined by default in vi command +mode and in emacs mode: +.Bl -column -offset indent "Esc O A, Esc O A" "em-exchange-mark" +.It Esc \&[ A, Esc O A Ta Ic ed-prev-history +.It Esc \&[ B, Esc O B Ta Ic ed-next-history +.It Esc \&[ C, Esc O C Ta Ic ed-next-char +.It Esc \&[ D, Esc O D Ta Ic ed-prev-char +.It Esc \&[ F, Esc O F Ta Ic ed-move-to-end +.It Esc \&[ H, Esc O H Ta Ic ed-move-to-beg +.El +.Pp +In vi command mode, they are also defined by default without the +initial escape character. +.Pp +In addition, the +.Nm +library tries to bind the strings generated by the arrow keys +as reported by the +.Xr terminfo 5 +database to these editor commands, unless that would clobber +user settings. +.Pp +In emacs mode, the two-character string +.Dq Ctrl-X Ctrl-X +is bound to the +.Ic em-exchange-mark +editor command. +.Ss Input Queue +The +.Nm +library maintains an input queue operated in FIFO mode. +Whenever it needs an input character, it takes the first character +from the first line of the input queue. +When the queue is empty, it reads from the terminal. +.Pp +A line can be appended to the end of the input queue in several ways: +.Bl -dash -offset indent +.It +By calling one of the keyboard +.Sx Macros . +.It +By calling the editor command +.Ic vi-redo . +.It +By calling the editor command +.Ic vi-alias . +.It +By pressing a key in emacs incremental search mode that doesn't +have a special meaning in that mode but returns to normal emacs +mode. +.It +If an application program directly calls the functions +.Xr el_push 3 +or +.Xr el_wpush 3 , +it can provide additional, program-specific ways +of appending to the input queue. +.El +.Sh SEE ALSO +.Xr mg 1 , +.Xr vi 1 , +.Xr editline 3 , +.Xr el_wgets 3 , +.Xr el_wpush 3 , +.Xr el_wset 3 , +.Xr editrc 5 +.Sh HISTORY +This manual page first appeared in +.Ox
