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

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 ,

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

be associated with this EditLine structure. It can be retrieved with -the corresponding -.Fn el_get -call. -.El -.It Fn el_get -Get -.Nm -parameters. -.Fa op -determines which parameter to retrieve into -.Fa result . -.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 *)" -Return a pointer to the function that displays the prompt. -.It Dv EL_RPROMPT , Fa "char *(*f)(EditLine *)" -Return a pointer to the function that displays the rightside prompt. -.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_SIGNAL , Fa "int *" -Return non-zero if -.Nm -has installed private signal handlers (see -.Fn el_get -above). -.It Dv EL_EDITMODE, Fa "int *" -Return non-zero if editing is enabled. -.It Dv EL_GETCFN, Fa "int (**f)(EditLine *, char *)" -Return a pointer to the function that read characters, which is equal to -``EL_BUILTIN_GETCFN'' in the case of the default builtin function. -.It Dv EL_CLIENTDATA , Fa "void **data" -Retrieve -.Fa data -previously registered with the corresponding -.Fn el_set -call. -.El -.It Fn el_source -Initialise -.Nm -by reading the contents of -.Fa file . -.Fn el_parse -is called for each line in -.Fa file . -If -.Fa file -is -.Dv NULL , -try -.Pa $PWD/.editrc -then -.Pa $HOME/.editrc . -Refer to -.Xr editrc 5 -for details on the format of -.Fa file . -.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_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;
