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 +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_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. 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. .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 "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 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 *(*f)(EditLine *)" , Fa "char *c" -Return a pointer to the function that displays the prompt in +Set .Fa f . +to a pointer to the function that displays the prompt. If .Fa c is not .Dv NULL , -return the start/stop literal prompt character in it. +set it to the start/stop literal prompt character. .It Dv EL_RPROMPT , Fa "char *(*f)(EditLine *)" , Fa "char *c" -Return a pointer to the function that displays the prompt in +Set .Fa f . +to a pointer to the function that displays the prompt.

If .Fa file is .Dv NULL , try .Pa $HOME/.editrc . Refer to .Xr editrc 5 for details on the format of .Fa file . .Fn el_source returns 0 on success and \-1 on error. .It Fn el_resize Must be called if the terminal size changes. If .Dv EL_SIGNAL has been set with .Fn el_set , then this is done automatically. Otherwise, it's the responsibility of the application to call .Fn el_resize on the appropriate occasions. .It Fn el_cursor Move the cursor to the right (if positive) or to the left (if negative) .Fa count characters. Returns the resulting offset of the cursor from the beginning of the line. .It Fn el_line Return the editing information for the current line in a .Fa LineInfo structure, which is defined as follows: .Bd -literal typedef struct lineinfo { const char *buffer; /* address of buffer */ const char *cursor; /* address of cursor */ const char *lastchar; /* address of last character */ } LineInfo; .Ed .Pp .Fa buffer is not NUL terminated. This function may be called after .Fn el_gets to obtain the .Fa LineInfo structure pertaining to line returned by that function, and from within user defined functions added with .Dv EL_ADDFN . .It Fn el_insertstr Insert .Fa str into the line at the cursor. Returns \-1 if .Fa str is empty or won't fit, and 0 otherwise. .It Fn el_deletestr Delete .Fa count characters before the cursor. .El .Sh HISTORY LIST FUNCTIONS The history functions use a common data structure, .Fa History , which is created by .Fn history_init and freed by .Fn history_end . .Pp The following functions are available: .Bl -tag -width 4n .It Fn history_init -Initialise the history list, and return a data structure +Initialize the history list, and return a data structure to be used by all other history list functions, or .Dv NULL on failure. .It Fn history_end Clean up and finish with .Fa h , assumed to have been created with .Fn history_init . .It Fn history Perform operation .Fa op on the history list, with optional arguments as needed by the operation. .Fa ev is changed accordingly to operation. The following values for .Fa op are supported, along with the required argument list: .Bl -tag -width 4n .It Dv H_SETSIZE , Fa "int size" Set size of history to .Fa size elements. .It Dv H_GETSIZE Get number of events currently in history. .It Dv H_END Cleans up and finishes with .Fa h , assumed to be created with .Fn history_init . .It Dv H_CLEAR Clear the history. .It Dv H_FUNC , Fa "void *ptr" , Fa "history_gfun_t first" , \ Fa "history_gfun_t next" , Fa "history_gfun_t last" , \ Fa "history_gfun_t prev" , Fa "history_gfun_t curr" , \ Fa "history_sfun_t set" , Fa "history_vfun_t clear" , \ Fa "history_efun_t enter" , Fa "history_efun_t add" Define functions to perform various history operations. .Fa ptr is the argument given to a function when it's invoked. .It Dv H_FIRST Return the first element in the history. .It Dv H_LAST Return the last element in the history. .It Dv H_PREV Return the previous element in the history. .It Dv H_NEXT Return the next element in the history. .It Dv H_CURR Return the current element in the history. .It Dv H_SET Set the cursor to point to the requested element. .It Dv H_ADD , Fa "const char *str" Append .Fa str to the current element of the history, or perform the .Dv H_ENTER operation with argument .Fa str if there is no current element. .It Dv H_APPEND , Fa "const char *str" Append .Fa str to the last new element of the history. .It Dv H_ENTER , Fa "const char *str" Add .Fa str as a new element to the history, and, if necessary, removing the oldest entry to keep the list to the created size. If .Dv H_SETUNIQUE has been called with a non-zero argument, the element will not be entered into the history if its contents match the ones of the current history element. If the element is entered .Fn history returns 1; if it is ignored as a duplicate returns 0. Finally .Fn history returns \-1 if an error occurred. .It Dv H_PREV_STR , Fa "const char *str" Return the closest previous event that starts with .Fa str . .It Dv H_NEXT_STR , Fa "const char *str" Return the closest next event that starts with .Fa str . .It Dv H_PREV_EVENT , Fa "int e" Return the previous event numbered .Fa e . .It Dv H_NEXT_EVENT , Fa "int e" Return the next event numbered .Fa e . .It Dv H_LOAD , Fa "const char *file" Load the history list stored in .Fa file . .It Dv H_SAVE , Fa "const char *file" Save the history list to .Fa file . .It Dv H_SAVE_FP , Fa "FILE *fp" Save the history list to the opened .Ft FILE pointer .Fa fp . .It Dv H_SETUNIQUE , Fa "int unique" Set flag that adjacent identical event strings should not be entered into the history. .It Dv H_GETUNIQUE Retrieve the current setting if adjacent identical elements should be entered into the history. .It Dv H_DEL , Fa "int e" Delete the event numbered .Fa e . This function is only provided for .Xr readline 3 compatibility. The caller is responsible for free'ing the string in the returned .Fa HistEvent . .El .Pp .Fn history returns \*[Gt]= 0 if the operation .Fa op succeeds. Otherwise, \-1 is returned and .Fa ev is updated to contain more details about the error. .El .Sh TOKENIZATION FUNCTIONS The tokenization functions use a common data structure, .Fa Tokenizer , which is created by .Fn tok_init and freed by .Fn tok_end . .Pp The following functions are available: .Bl -tag -width 4n .It Fn tok_init -Initialise the tokenizer, and return a data structure +Initialize the tokenizer, and return a data structure to be used by all other tokenizer functions. .Fa IFS contains the Input Field Separators, which defaults to .Aq space , .Aq tab , and .Aq newline if .Dv NULL . .It Fn tok_end Clean up and finish with .Fa t , assumed to have been created with .Fn tok_init . .It Fn tok_reset Reset the tokenizer state. Use after a line has been successfully tokenized by .Fn tok_line or .Fn tok_str and before a new line is to be tokenized. .It Fn tok_line Tokenize .Fa li , If successful, modify: .Fa argv to contain the words, .Fa argc to contain the number of words, .Fa cursorc (if not .Dv NULL ) to contain the index of the word containing the cursor, and .Fa cursoro (if not .Dv NULL ) to contain the offset within .Fa argv[cursorc] of the cursor. .Pp Returns 0 if successful, \-1 for an internal error, 1 for an unmatched single quote, 2 for an unmatched double quote, and 3 for a backslash quoted .Aq newline . A positive exit code indicates that another line should be read and tokenization attempted again. . .It Fn tok_str A simpler form of .Fn tok_line ; .Fa str is a NUL terminated string to tokenize. .El . .\"XXX.Sh EXAMPLES .\"XXX: provide some examples .Sh SEE ALSO .Xr sh 1 , .Xr signal 3 , .Xr termcap 3 , .Xr editrc 5 , .Xr termcap 5 .Sh HISTORY The .Nm library first appeared in .Bx 4.4 . .Dv CC_REDISPLAY appeared in .Nx 1.3 . .Dv CC_REFRESH_BEEP , .Dv EL_EDITMODE and the readline emulation appeared in .Nx 1.4 . .Dv EL_RPROMPT appeared in .Nx 1.5 . .Sh AUTHORS .An -nosplit The .Nm library was written by .An Christos Zoulas . .An Luke Mewburn wrote this manual and implemented .Dv CC_REDISPLAY , .Dv CC_REFRESH_BEEP , .Dv EL_EDITMODE , and .Dv EL_RPROMPT . .An Jaromir Dolecek implemented the readline emulation. .An Johny Mattsson implemented wide-character support. .Sh BUGS At this time, it is the responsibility of the caller to check the result of the .Dv EL_EDITMODE operation of .Fn el_get (after an .Fn el_source or .Fn el_parse ) to determine if .Nm should be used for further input.
