For such programs, the default behaviour of +Readline is sufficient. This section describes how to use Readline in +the simplest way possible, perhaps to replace calls in your code to +@code{gets ()}. + +@findex readline () +@cindex readline, function +The function @code{readline} prints a prompt and then reads and returns +a single line of text from the user. The line which @code{readline ()} +returns is allocated with @code{malloc ()}; you should @code{free ()} +the line when you are done with it. The declaration in ANSI C is + +@example +@code{char *readline (char *@var{prompt});} +@end example + +So, one might say +@example +@code{char *line = readline ("Enter a line: ");} +@end example +in order to read a line of text from the user. + +The line which is returned has the final newline removed, so only the +text of the line remains. + +If readline encounters an EOF while reading the line, and the line is +empty at that point, then @code{(char *)NULL} is returned. Otherwise, +the line is ended just as if a newline was typed. + +If you want the user to be able to get at the line later, (with +@key{C-p} for example), you must call @code{add_history ()} to save the +line away in a @dfn{history} list of such lines. + +@example +@code{add_history (line)}; +@end example + +For full details on the GNU History Library, see the associated manual. + +It is polite to avoid saving empty lines on the history list, since +no one has a burning need to reuse a blank line. Here is a function +which usefully replaces the standard @code{gets ()} library function: + +@example +/* A static variable for holding the line. */ +static char *my_gets_line = (char *)NULL; + +/* Read a string, and return a pointer to it. Returns NULL on EOF. */ +char * +my_gets () +@{ + /* If the buffer has already been allocated, return the memory + to the free pool. */ + if (my_gets_line != (char *)NULL) + free (my_gets_line); + + /* Get a line from the user. */ + my_gets_line = readline (""); + + /* If the line has any text in it, save it on the history. */ + if (my_get_line && *my_gets_line) + add_history (my_gets_line); + + return (my_gets_line); +@} +@end example + +The above code gives the user the default behaviour of @key{TAB} +completion: completion on file names. If you do not want readline to +complete on filenames, you can change the binding of the @key{TAB} key +with @code{rl_bind_key ()}. + +@findex rl_bind_key () + +@example +@code{int rl_bind_key (int @var{key}, (int (*)())@var{function});} +@end example + +@code{rl_bind_key ()} takes 2 arguments; @var{key} is the character that +you want to bind, and @var{function} is the address of the function to +run when @var{key} is pressed. Binding @key{TAB} to @code{rl_insert ()} +makes @key{TAB} just insert itself. + +@code{rl_bind_key ()} returns non-zero if @var{key} is not a valid +ASCII character code (between 0 and 255). + +@example +@code{rl_bind_key ('\t', rl_insert);} +@end example + +@node Custom Functions, Custom Completers, Default Behaviour, Readline Technical +@section Custom Functions + +Readline provides a great many functions for manipulating the text of +the line.

This is done by representing the function with a descriptive +name. The user is able to type the descriptive name when referring to +the function. Thus, in an init file, one might find + +@example +Meta-Rubout: backward-kill-word +@end example + +This binds @key{Meta-Rubout} to the function @emph{descriptively} named +@code{backward-kill-word}. You, as a programmer, should bind the +functions you write to descriptive names as well. Here is how to do +that. + +@defun rl_add_defun (char *name, Function *function, int key) +Add @var{name} to the list of named functions. Make @var{function} be +the function that gets called. If @var{key} is not -1, then bind it to +@var{function} using @code{rl_bind_key ()}. +@end defun + +Using this function alone is sufficient for most applications. It is +the recommended way to add a few functions to the default functions that +Readline has built in already. If you need to do more or different +things than adding a function to Readline, you may need to use the +underlying functions described below. + +@node Keymaps, Binding Keys, Function Naming, Custom Functions +@subsection Selecting a Keymap + +Key bindings take place on a @dfn{keymap}. The keymap is the +association between the keys that the user types and the functions that +get run. You can make your own keymaps, copy existing keymaps, and tell +Readline which keymap to use. + +@defun rl_make_bare_keymap () +Returns a new, empty keymap. The space for the keymap is allocated with +@code{malloc ()}; you should @code{free ()} it when you are done. +@end defun + +@defun rl_copy_keymap (Keymap map) +Return a new keymap which is a copy of @var{map}. +@end defun + +@defun rl_make_keymap () +Return a new keymap with the printing characters bound to rl_insert, +the lowercase Meta characters bound to run their equivalents, and +the Meta digits bound to produce numeric arguments. +@end defun + +@node Binding Keys, Function Writing, Keymaps, Custom Functions +@subsection Binding Keys + +You associate keys with functions through the keymap. Here are +the functions for doing that. + +@defun rl_bind_key (int key, Function *function) +Binds @var{key} to @var{function} in the currently selected keymap. +Returns non-zero in the case of an invalid @var{key}. +@end defun + +@defun rl_bind_key_in_map (int key, Function *function, Keymap map) +Bind @var{key} to @var{function} in @var{map}. Returns non-zero in the case +of an invalid @var{key}. +@end defun + +@defun rl_unbind_key (int key) +Make @var{key} do nothing in the currently selected keymap. +Returns non-zero in case of error. +@end defun + +@defun rl_unbind_key_in_map (int key, Keymap map) +Make @var{key} be bound to the null function in @var{map}. +Returns non-zero in case of error. +@end defun + +@node Function Writing, Allowing Undoing, Binding Keys, Custom Functions +@subsection Writing a New Function + +In order to write new functions for Readline, you need to know the +calling conventions for keyboard invoked functions, and the names of the +variables that describe the current state of the line gathered so far. + +@defvar char *rl_line_buffer +This is the line gathered so far. You are welcome to modify the +contents of this, but see Undoing, below. +@end defvar + +@defvar int rl_point +The offset of the current cursor position in @var{rl_line_buffer}. +@end defvar + +@defvar int rl_end +The number of characters present in @code{rl_line_buffer}.

In general, if a +function uses the numeric argument as a repeat count, it should be able +to do something useful with a negative argument as well as a positive +argument. At the very least, it should be aware that it can be passed a +negative argument. + +@node Allowing Undoing, , Function Writing, Custom Functions +@subsection Allowing Undoing + +Supporting the undo command is a painless thing to do, and makes your +function much more useful to the end user. It is certainly easy to try +something if you know you can undo it. I could use an undo function for +the stock market. + +If your function simply inserts text once, or deletes text once, and it +calls @code{rl_insert_text ()} or @code{rl_delete_text ()} to do it, then +undoing is already done for you automatically, and you can safely skip +this section. + +If you do multiple insertions or multiple deletions, or any combination +of these operations, you will want to group them together into one +operation. This can be done with @code{rl_begin_undo_group ()} and +@code{rl_end_undo_group ()}. + +@defun rl_begin_undo_group () +Begins saving undo information in a group construct. The undo +information usually comes from calls to @code{rl_insert_text ()} and +@code{rl_delete_text ()}, but they could be direct calls to +@code{rl_add_undo ()}. +@end defun + +@defun rl_end_undo_group () +Closes the current undo group started with @code{rl_begin_undo_group +()}. There should be exactly one call to @code{rl_end_undo_group ()} +for every call to @code{rl_begin_undo_group ()}. +@end defun + +Finally, if you neither insert nor delete text, but directly modify the +existing text (e.g. change its case), you call @code{rl_modifying ()} +once, just before you modify the text. You must supply the indices of +the text range that you are going to modify. + +@defun rl_modifying (int start, int end) +Tell Readline to save the text between @var{start} and @var{end} as a +single undo unit. It is assumed that subsequent to this call you will +modify that range of text in some way. +@end defun + +@subsection An Example + +Let us say that we are actually going to put an example here. + +@node Custom Completers, Variable Index, Custom Functions, Readline Technical + +Typically, a program that reads commands from the user has a way of +disambiguating between commands and data.
