+@node Programming with GNU Readline
+@chapter Programming with GNU Readline
+
+This chapter describes the interface between the @sc{gnu} Readline Library and
+other programs.  If you are a programmer, and you wish to include the
+features found in @sc{gnu} Readline
+such as completion, line editing, and interactive history manipulation
+in your own programs, this section is for you.
+
+@menu
+* Basic Behavior::	Using the default behavior of Readline.
+* Custom Functions::	Adding your own functions to Readline.
+* Readline Variables::			Variables accessible to custom
+					functions.
+* Readline Convenience Functions::	Functions which Readline supplies to
+					aid in writing your own custom

+@end menu
+
+@node Basic Behavior
+@section Basic Behavior
+
+Many programs provide a command line interface, such as @code{mail},
+@code{ftp}, and @code{sh}.  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()} or @code{fgets()}.
+
+@findex readline
+@cindex readline, function
+
+The function @code{readline()} prints a prompt @var{prompt}
+and then reads and returns a single line of text from the user.
+If @var{prompt} is @code{NULL} or the empty string, no prompt is displayed.
+The line @code{readline} returns is allocated with @code{malloc()};
+the caller should @code{free()} the line when it has finished with it.
+The declaration for @code{readline} in ANSI C is
+
+@example
+@code{char *readline (const char *@var{prompt});}
+@end example
+
+@noindent
+So, one might say
+@example
+@code{char *line = readline ("Enter a line: ");}
+@end example
+@noindent
+in order to read a line of text from the user.
+The line returned has the final newline removed, so only the
+text remains.
+
+If @code{readline} encounters an @code{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 had been 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
+
+@noindent
+For full details on the GNU History Library, see the associated manual.
+
+It is preferable to avoid saving empty lines on the history list, since
+users rarely have a burning need to reuse a blank line.  Here is
+a function which usefully replaces the standard @code{gets()} library
+function, and has the advantage of no static buffer to overflow:
+
+@example
+/* A static variable for holding the line. */
+static char *line_read = (char *)NULL;
+
+/* Read a string, and return a pointer to it.
+   Returns NULL on EOF. */
+char *
+rl_gets ()
+@{
+  /* If the buffer has already been allocated,
+     return the memory to the free pool. */
+  if (line_read)
+    @{
+      free (line_read);
+      line_read = (char *)NULL;
+    @}
+
+  /* Get a line from the user. */
+  line_read = readline ("");
+
+  /* If the line has any text in it,
+     save it on the history. */
+  if (line_read && *line_read)
+    add_history (line_read);
+
+  return (line_read);
+@}
+@end example
+
+This function 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()}.
+
+@example
+@code{int rl_bind_key (int @var{key}, rl_command_func_t *@var{function});}
+@end example
+
+@code{rl_bind_key()} takes two arguments: @var{key} is the character that
+you want to bind, and @var{function} is the address of the function to
+call when @var{key} is pressed.  Binding @key{TAB} to @code{rl_insert()}
+makes @key{TAB} insert itself.
+@code{rl_bind_key()} returns non-zero if @var{key} is not a valid
+ASCII character code (between 0 and 255).
+
+Thus, to disable the default @key{TAB} behavior, the following suffices:
+@example
+@code{rl_bind_key ('\t', rl_insert);}
+@end example
+
+This code should be executed once at the start of your program; you
+might write a function called @code{initialize_readline()} which
+performs this and other desired initializations, such as installing
+custom completers (@pxref{Custom Completers}).
+
+@node Custom Functions
+@section Custom Functions
+
+Readline provides many functions for manipulating the text of
+the line, but it isn't possible to anticipate the needs of all
+programs.  This section describes the various functions and variables
+defined within the Readline library which allow a user program to add
+customized functionality to Readline.
+
+Before declaring any functions that customize Readline's behavior, or
+using any functionality Readline provides in other code, an
+application writer should include the file @code{<readline/readline.h>}
+in any file that uses Readline's features.  Since some of the definitions
+in @code{readline.h} use the @code{stdio} library, the file
+@code{<stdio.h>} should be included before @code{readline.h}.
+
+@code{readline.h} defines a C preprocessor variable that should
+be treated as an integer, @code{RL_READLINE_VERSION}, which may
+be used to conditionally compile application code depending on
+the installed Readline version.  The value is a hexadecimal
+encoding of the major and minor version numbers of the library,
+of the form 0x@var{MMmm}.  @var{MM} is the two-digit major
+version number; @var{mm} is the two-digit minor version number. 
+For Readline 4.2, for example, the value of
+@code{RL_READLINE_VERSION} would be @code{0x0402}. 
+
+@menu
+* Readline Typedefs::	C declarations to make code readable.
+* Function Writing::	Variables and calling conventions.
+@end menu
+
+@node Readline Typedefs
+@subsection Readline Typedefs
+
+For readabilty, we declare a number of new object types, all pointers
+to functions.
+
+The reason for declaring these new types is to make it easier to write
+code describing pointers to C functions with appropriately prototyped
+arguments and return values.
+
+For instance, say we want to declare a variable @var{func} as a pointer
+to a function which takes two @code{int} arguments and returns an
+@code{int} (this is the type of all of the Readline bindable functions).
+Instead of the classic C declaration
+
+@code{int (*func)();}
+
+@noindent
+or the ANSI-C style declaration
+
+@code{int (*func)(int, int);}
+
+@noindent
+we may write
+
+@code{rl_command_func_t *func;}
+
+The full list of function pointer types available is
+
+@table @code
+@item typedef int rl_command_func_t (int, int);
+
+@item typedef char *rl_compentry_func_t (const char *, int);
+
+@item typedef char **rl_completion_func_t (const char *, int, int);
+
+@item typedef char *rl_quote_func_t (char *, int, char *);
+
+@item typedef char *rl_dequote_func_t (char *, int);
+
+@item typedef int rl_compignore_func_t (char **);
+
+@item typedef void rl_compdisp_func_t (char **, int, int);
+
+@item typedef int rl_hook_func_t (void);
+
+@item typedef int rl_getc_func_t (FILE *);
+
+@item typedef int rl_linebuf_func_t (char *, int);
+
+@item typedef int rl_intfunc_t (int);
+@item #define rl_ivoidfunc_t rl_hook_func_t
+@item typedef int rl_icpfunc_t (char *);
+@item typedef int rl_icppfunc_t (char **);
+
+@item typedef void rl_voidfunc_t (void);

+@item typedef void rl_vcpfunc_t (char *);
+@item typedef void rl_vcppfunc_t (char **);
+
+@end table
+
+@node Function Writing
+@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 read so far.
+
+The calling sequence for a command @code{foo} looks like
+
+@example
+@code{int foo (int count, int key)}
+@end example
+
+@noindent
+where @var{count} is the numeric argument (or 1 if defaulted) and
+@var{key} is the key that invoked this function.
+
+It is completely up to the function as to what should be done with the
+numeric argument.  Some functions use it as a repeat count, some
+as a flag, and others to choose alternate behavior (refreshing the current
+line as opposed to refreshing the screen, for example).  Some choose to
+ignore it.  In general, if a
+function uses the numeric argument as a repeat count, it should be able
+to do something useful with both negative and positive arguments.
+At the very least, it should be aware that it can be passed a
+negative argument.
+
+A command function should return 0 if its action completes successfully,
+and a non-zero value if some error occurs.
+This is the convention obeyed by all of the builtin Readline bindable
+command functions.
+
+@node Readline Variables
+@section Readline Variables
+
+These variables are available to function writers.
+
+@deftypevar {char *} rl_line_buffer
+This is the line gathered so far.  You are welcome to modify the
+contents of the line, but see @ref{Allowing Undoing}.  The
+function @code{rl_extend_line_buffer} is available to increase
+the memory allocated to @code{rl_line_buffer}.
+@end deftypevar
+
+@deftypevar int rl_point
+The offset of the current cursor position in @code{rl_line_buffer}
+(the @emph{point}).
+@end deftypevar
+
+@deftypevar int rl_end
+The number of characters present in @code{rl_line_buffer}.  When
+@code{rl_point} is at the end of the line, @code{rl_point} and
+@code{rl_end} are equal.
+@end deftypevar
+
+@deftypevar int rl_mark
+The @var{mark} (saved position) in the current line.  If set, the mark
+and point define a @emph{region}.
+@end deftypevar
+
+@deftypevar int rl_done
+Setting this to a non-zero value causes Readline to return the current
+line immediately.
+@end deftypevar
+
+@deftypevar int rl_num_chars_to_read
+Setting this to a positive value before calling @code{readline()} causes
+Readline to return after accepting that many characters, rather
+than reading up to a character bound to @code{accept-line}.
+@end deftypevar
+
+@deftypevar int rl_pending_input
+Setting this to a value makes it the next keystroke read.  This is a
+way to stuff a single character into the input stream.
+@end deftypevar
+
+@deftypevar int rl_dispatching
+Set to a non-zero value if a function is being called from a key binding;
+zero otherwise.  Application functions can test this to discover whether
+they were called directly or by Readline's dispatching mechanism.
+@end deftypevar
+
+@deftypevar int rl_erase_empty_line
+Setting this to a non-zero value causes Readline to completely erase
+the current line, including any prompt, any time a newline is typed as
+the only character on an otherwise-empty line.  The cursor is moved to

+
+@deftypevar {char *} rl_prompt
+The prompt Readline uses.  This is set from the argument to

+@end deftypevar
+
+@deftypevar int rl_already_prompted
+If an application wishes to display the prompt itself, rather than have
+Readline do it the first time @code{readline()} is called, it should set
+this variable to a non-zero value after displaying the prompt.
+The prompt must also be passed as the argument to @code{readline()} so
+the redisplay functions can update the display properly.

+An integer encoding the current version of the library.  The encoding is
+of the form 0x@var{MMmm}, where @var{MM} is the two-digit major version
+number, and @var{mm} is the two-digit minor version number.

+The stdio stream to which Readline performs output.
+If @code{NULL}, Readline defaults to @var{stdout}.
+@end deftypevar
+
+@deftypevar int rl_prefer_env_winsize
+If non-zero, Readline gives values found in the @env{LINES} and

+@node Function Naming
+@subsection Naming a Function
+
+The user can dynamically change the bindings of keys while using
+Readline.  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 the keystroke @key{Meta-Rubout} to the function
+@emph{descriptively} named @code{backward-kill-word}.  You, as the
+programmer, should bind the functions you write to descriptive names as
+well.  Readline provides a function for doing that:
+
+@deftypefun int rl_add_defun (const char *name, rl_command_func_t *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 deftypefun
+
+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.
+If you need to do something other than adding a function to Readline,
+you may need to use the underlying functions described below.
+
+@node Keymaps
+@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.
+
+@deftypefun Keymap rl_make_bare_keymap (void)
+Returns a new, empty keymap.  The space for the keymap is allocated with
+@code{malloc()}; the caller should free it by calling
+@code{rl_free_keymap()} when done.
+@end deftypefun
+
+@deftypefun Keymap rl_copy_keymap (Keymap map)
+Return a new keymap which is a copy of @var{map}.
+@end deftypefun
+
+@deftypefun Keymap rl_make_keymap (void)
+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 deftypefun
+
+@deftypefun void rl_discard_keymap (Keymap keymap)
+Free the storage associated with the data in @var{keymap}.
+The caller should free @var{keymap}.
+@end deftypefun
+
+@deftypefun void rl_free_keymap (Keymap keymap)
+Free all storage associated with @var{keymap}.  This calls
+@code{rl_discard_keymap} to free subordindate keymaps and macros.
+@end deftypefun
+
+Readline has several internal keymaps.  These functions allow you to
+change which keymap is active.
+
+@deftypefun Keymap rl_get_keymap (void)
+Returns the currently active keymap.
+@end deftypefun
+
+@deftypefun void rl_set_keymap (Keymap keymap)
+Makes @var{keymap} the currently active keymap.
+@end deftypefun
+
+@deftypefun Keymap rl_get_keymap_by_name (const char *name)
+Return the keymap matching @var{name}.  @var{name} is one which would
+be supplied in a @code{set keymap} inputrc line (@pxref{Readline Init File}).
+@end deftypefun
+
+@deftypefun {char *} rl_get_keymap_name (Keymap keymap)
+Return the name matching @var{keymap}.  @var{name} is one which would
+be supplied in a @code{set keymap} inputrc line (@pxref{Readline Init File}).
+@end deftypefun
+
+@node Binding Keys
+@subsection Binding Keys
+
+Key sequences are associate with functions through the keymap.
+Readline has several internal keymaps: @code{emacs_standard_keymap},
+@code{emacs_meta_keymap}, @code{emacs_ctlx_keymap},
+@code{vi_movement_keymap}, and @code{vi_insertion_keymap}.
+@code{emacs_standard_keymap} is the default, and the examples in
+this manual assume that.
+
+Since @code{readline()} installs a set of default key bindings the first
+time it is called, there is always the danger that a custom binding
+installed before the first call to @code{readline()} will be overridden.
+An alternate mechanism is to install custom key bindings in an
+initialization function assigned to the @code{rl_startup_hook} variable
+(@pxref{Readline Variables}).
+
+These functions manage key bindings.
+
+@deftypefun int rl_bind_key (int key, rl_command_func_t *function)

+
+@deftypefun int rl_generic_bind (int type, const char *keyseq, char *data, Keymap map)
+Bind the key sequence represented by the string @var{keyseq} to the arbitrary

+@node Allowing Undoing
+@subsection Allowing Undoing
+
+Supporting the undo command is a painless thing, and makes your
+functions much more useful.  It is certainly easy to try
+something if you know you can undo it.
+
+If your function simply inserts text once, or deletes text once, and
+uses @code{rl_insert_text()} or @code{rl_delete_text()} to do it, then
+undoing is already done for you automatically.
+
+If you do multiple insertions or multiple deletions, or any combination
+of these operations, you should group them together into one operation.
+This is done with @code{rl_begin_undo_group()} and
+@code{rl_end_undo_group()}.
+
+The types of events that can be undone are:
+
+@smallexample
+enum undo_code @{ UNDO_DELETE, UNDO_INSERT, UNDO_BEGIN, UNDO_END @}; 
+@end smallexample
+
+Notice that @code{UNDO_DELETE} means to insert some text, and
+@code{UNDO_INSERT} means to delete some text.  That is, the undo code
+tells what to undo, not how to undo it.  @code{UNDO_BEGIN} and
+@code{UNDO_END} are tags added by @code{rl_begin_undo_group()} and
+@code{rl_end_undo_group()}.
+
+@deftypefun int rl_begin_undo_group (void)
+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 could be the result of calls to
+@code{rl_add_undo()}.
+@end deftypefun
+
+@deftypefun int rl_end_undo_group (void)
+Closes the current undo group started with @code{rl_begin_undo_group
+()}.  There should be one call to @code{rl_end_undo_group()}
+for each call to @code{rl_begin_undo_group()}.
+@end deftypefun
+
+@deftypefun void rl_add_undo (enum undo_code what, int start, int end, char *text)
+Remember how to undo an event (according to @var{what}).  The affected
+text runs from @var{start} to @var{end}, and encompasses @var{text}.
+@end deftypefun
+
+@deftypefun void rl_free_undo_list (void)
+Free the existing undo list.
+@end deftypefun
+
+@deftypefun int rl_do_undo (void)
+Undo the first thing on the undo list.  Returns @code{0} if there was
+nothing to undo, non-zero if something was undone.
+@end deftypefun
+
+Finally, if you neither insert nor delete text, but directly modify the
+existing text (e.g., change its case), 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.
+
+@deftypefun int 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 you will subsequently modify
+that text.

+@node Readline Signal Handling
+@section Readline Signal Handling
+
+Signals are asynchronous events sent to a process by the Unix kernel,
+sometimes on behalf of another process.  They are intended to indicate
+exceptional events, like a user pressing the interrupt key on his terminal,
+or a network connection being broken.  There is a class of signals that can
+be sent to the process currently reading input from the keyboard.  Since
+Readline changes the terminal attributes when it is called, it needs to
+perform special processing when such a signal is received in order to
+restore the terminal to a sane state, or provide application writers with
+functions to do so manually. 
+
+Readline contains an internal signal handler that is installed for a
+number of signals (@code{SIGINT}, @code{SIGQUIT}, @code{SIGTERM},
+@code{SIGALRM}, @code{SIGTSTP}, @code{SIGTTIN}, and @code{SIGTTOU}).
+When one of these signals is received, the signal handler
+will reset the terminal attributes to those that were in effect before
+@code{readline()} was called, reset the signal handling to what it was
+before @code{readline()} was called, and resend the signal to the calling
+application.
+If and when the calling application's signal handler returns, Readline
+will reinitialize the terminal and continue to accept input.
+When a @code{SIGINT} is received, the Readline signal handler performs
+some additional work, which will cause any partially-entered line to be
+aborted (see the description of @code{rl_free_line_state()} below).
+
+There is an additional Readline signal handler, for @code{SIGWINCH}, which
+the kernel sends to a process whenever the terminal's size changes (for
+example, if a user resizes an @code{xterm}).  The Readline @code{SIGWINCH}
+handler updates Readline's internal screen size information, and then calls
+any @code{SIGWINCH} signal handler the calling application has installed. 
+Readline calls the application's @code{SIGWINCH} signal handler without
+resetting the terminal to its original state.  If the application's signal
+handler does more than update its idea of the terminal size and return (for
+example, a @code{longjmp} back to a main processing loop), it @emph{must}
+call @code{rl_cleanup_after_signal()} (described below), to restore the
+terminal state. 
+
+Readline provides two variables that allow application writers to
+control whether or not it will catch certain signals and act on them
+when they are received.  It is important that applications change the
+values of these variables only when calling @code{readline()}, not in
+a signal handler, so Readline's internal signal state is not corrupted.
+
+@deftypevar int rl_catch_signals
+If this variable is non-zero, Readline will install signal handlers for
+@code{SIGINT}, @code{SIGQUIT}, @code{SIGTERM}, @code{SIGALRM},
+@code{SIGTSTP}, @code{SIGTTIN}, and @code{SIGTTOU}.
+
+The default value of @code{rl_catch_signals} is 1.
+@end deftypevar
+
+@deftypevar int rl_catch_sigwinch
+If this variable is non-zero, Readline will install a signal handler for
+@code{SIGWINCH}.
+
+The default value of @code{rl_catch_sigwinch} is 1.
+@end deftypevar
+
+If an application does not wish to have Readline catch any signals, or
+to handle signals other than those Readline catches (@code{SIGHUP},
+for example), 
+Readline provides convenience functions to do the necessary terminal
+and internal state cleanup upon receipt of a signal.
+
+@deftypefun void rl_cleanup_after_signal (void)
+This function will reset the state of the terminal to what it was before
+@code{readline()} was called, and remove the Readline signal handlers for
+all signals, depending on the values of @code{rl_catch_signals} and
+@code{rl_catch_sigwinch}.
+@end deftypefun
+
+@deftypefun void rl_free_line_state (void)
+This will free any partial state associated with the current input line
+(undo information, any partial history entry, any partially-entered
+keyboard macro, and any partially-entered numeric argument).  This
+should be called before @code{rl_cleanup_after_signal()}.  The
+Readline signal handler for @code{SIGINT} calls this to abort the
+current input line.
+@end deftypefun
+
+@deftypefun void rl_reset_after_signal (void)
+This will reinitialize the terminal and reinstall any Readline signal
+handlers, depending on the values of @code{rl_catch_signals} and

+@end deftypefun
+
+If an application does not wish Readline to catch @code{SIGWINCH}, it may
+call @code{rl_resize_terminal()} or @code{rl_set_screen_size()} to force

+is received.
+
+@deftypefun void rl_echo_signal_char (int sig)
+If an application wishes to install its own signal handlers, but still
+have readline display characters that generate signals, calling this
+function with @var{sig} set to @code{SIGINT}, @code{SIGQUIT}, or
+@code{SIGTSTP} will display the character generating that signal.

+@end deftypefun
+
+If an application does not want to install a @code{SIGWINCH} handler, but

+@end menu
+
+@node How Completing Works
+@subsection How Completing Works
+
+In order to complete some text, the full list of possible completions
+must be available.  That is, it is not possible to accurately
+expand a partial word without knowing all of the possible words
+which make sense in that context.  The Readline library provides
+the user interface to completion, and two of the most common
+completion functions:  filename and username.  For completing other types
+of text, you must write your own completion function.  This section
+describes exactly what such functions must do, and provides an example.
+
+There are three major functions used to perform completion:
+
+@enumerate
+@item
+The user-interface function @code{rl_complete()}.  This function is
+called with the same arguments as other bindable Readline functions:
+@var{count} and @var{invoking_key}.
+It isolates the word to be completed and calls
+@code{rl_completion_matches()} to generate a list of possible completions.
+It then either lists the possible completions, inserts the possible
+completions, or actually performs the
+completion, depending on which behavior is desired.
+
+@item
+The internal function @code{rl_completion_matches()} uses an
+application-supplied @dfn{generator} function to generate the list of
+possible matches, and then returns the array of these matches.
+The caller should place the address of its generator function in
+@code{rl_completion_entry_function}.
+
+@item
+The generator function is called repeatedly from
+@code{rl_completion_matches()}, returning a string each time.  The
+arguments to the generator function are @var{text} and @var{state}.
+@var{text} is the partial word to be completed.  @var{state} is zero the
+first time the function is called, allowing the generator to perform
+any necessary initialization, and a positive non-zero integer for
+each subsequent call.  The generator function returns
+@code{(char *)NULL} to inform @code{rl_completion_matches()} that there are
+no more possibilities left.  Usually the generator function computes the
+list of possible completions when @var{state} is zero, and returns them
+one at a time on subsequent calls.  Each string the generator function
+returns as a match must be allocated with @code{malloc()}; Readline
+frees the strings when it has finished with them.
+Such a generator function is referred to as an
+@dfn{application-specific completion function}.
+
+@end enumerate
+
+@deftypefun int rl_complete (int ignore, int invoking_key)
+Complete the word at or before point.  You have supplied the function

+@end deftypefun
+
+@deftypevar {rl_compentry_func_t *} rl_completion_entry_function
+This is a pointer to the generator function for
+@code{rl_completion_matches()}.
+If the value of @code{rl_completion_entry_function} is
+@code{NULL} then the default filename generator
+function, @code{rl_filename_completion_function()}, is used.
+An @dfn{application-specific completion function} is a function whose

+return values are used to  generate possible completions.

+
+@node Completion Functions
+@subsection Completion Functions
+
+Here is the complete list of callable completion functions present in
+Readline.
+
+@deftypefun int rl_complete_internal (int what_to_do)
+Complete the word at or before point.  @var{what_to_do} says what to do
+with the completion.  A value of @samp{?} means list the possible
+completions.  @samp{TAB} means do standard completion.  @samp{*} means
+insert all of the possible completions.  @samp{!} means to display
+all of the possible completions, if there is more than one, as well as
+performing partial completion.  @samp{@@} is similar to @samp{!}, but
+possible completions are not listed if the possible completions share
+a common prefix.
+@end deftypefun
+
+@deftypefun int rl_complete (int ignore, int invoking_key)
+Complete the word at or before point.  You have supplied the function
+that does the initial simple matching selection algorithm (see
+@code{rl_completion_matches()} and @code{rl_completion_entry_function}).
+The default is to do filename
+completion.  This calls @code{rl_complete_internal()} with an
+argument depending on @var{invoking_key}.
+@end deftypefun
+
+@deftypefun int rl_possible_completions (int count, int invoking_key)
+List the possible completions.  See description of @code{rl_complete
+()}.  This calls @code{rl_complete_internal()} with an argument of
+@samp{?}.
+@end deftypefun
+
+@deftypefun int rl_insert_completions (int count, int invoking_key)
+Insert the list of possible completions into the line, deleting the
+partially-completed word.  See description of @code{rl_complete()}.
+This calls @code{rl_complete_internal()} with an argument of @samp{*}.
+@end deftypefun
+
+@deftypefun int rl_completion_mode (rl_command_func_t *cfunc)
+Returns the apppriate value to pass to @code{rl_complete_internal()}
+depending on whether @var{cfunc} was called twice in succession and
+the values of the @code{show-all-if-ambiguous} and
+@code{show-all-if-unmodified} variables.
+Application-specific completion functions may use this function to present
+the same interface as @code{rl_complete()}.
+@end deftypefun
+
+@deftypefun {char **} rl_completion_matches (const char *text, rl_compentry_func_t *entry_func)
+Returns an array of strings which is a list of completions for
+@var{text}.  If there are no completions, returns @code{NULL}.
+The first entry in the returned array is the substitution for @var{text}.
+The remaining entries are the possible completions.  The array is
+terminated with a @code{NULL} pointer.
+
+@var{entry_func} is a function of two args, and returns a
+@code{char *}.  The first argument is @var{text}.  The second is a
+state argument; it is zero on the first call, and non-zero on subsequent
+calls.  @var{entry_func} returns a @code{NULL}  pointer to the caller
+when there are no more matches.
+@end deftypefun
+
+@deftypefun {char *} rl_filename_completion_function (const char *text, int state)
+A generator function for filename completion in the general case.
+@var{text} is a partial filename.
+The Bash source is a useful reference for writing application-specific
+completion functions (the Bash completion functions call this and other
+Readline functions).
+@end deftypefun
+
+@deftypefun {char *} rl_username_completion_function (const char *text, int state)
+A completion generator for usernames.  @var{text} contains a partial
+username preceded by a random character (usually @samp{~}).  As with all
+completion generators, @var{state} is zero on the first call and non-zero
+for subsequent calls.
+@end deftypefun
+
+@node Completion Variables
+@subsection Completion Variables
+
+@deftypevar {rl_compentry_func_t *} rl_completion_entry_function
+A pointer to the generator function for @code{rl_completion_matches()}.
+@code{NULL} means to use @code{rl_filename_completion_function()},
+the default filename completer.
+@end deftypevar
+
+@deftypevar {rl_completion_func_t *} rl_attempted_completion_function
+A pointer to an alternative function to create matches.
+The function is called with @var{text}, @var{start}, and @var{end}.
+@var{start} and @var{end} are indices in @code{rl_line_buffer} defining
+the boundaries of @var{text}, which is a character string.
+If this function exists and returns @code{NULL}, or if this variable is
+set to @code{NULL}, then @code{rl_complete()} will call the value of
+@code{rl_completion_entry_function} to generate matches, otherwise the
+array of strings returned will be used.
+If this function sets the @code{rl_attempted_completion_over}
+variable to a non-zero value, Readline will not perform its default
+completion even if this function returns no matches.
+@end deftypevar
+
+@deftypevar {rl_quote_func_t *} rl_filename_quoting_function
+A pointer to a function that will quote a filename in an
+application-specific fashion.  This is called if filename completion is being
+attempted and one of the characters in @code{rl_filename_quote_characters}
+appears in a completed filename.  The function is called with
+@var{text}, @var{match_type}, and @var{quote_pointer}.  The @var{text}
+is the filename to be quoted.  The @var{match_type} is either
+@code{SINGLE_MATCH}, if there is only one completion match, or
+@code{MULT_MATCH}.  Some functions use this to decide whether or not to
+insert a closing quote character.  The @var{quote_pointer} is a pointer
+to any opening quote character the user typed.  Some functions choose
+to reset this character.
+@end deftypevar
+
+@deftypevar {rl_dequote_func_t *} rl_filename_dequoting_function
+A pointer to a function that will remove application-specific quoting
+characters from a filename before completion is attempted, so those
+characters do not interfere with matching the text against names in
+the filesystem.  It is called with @var{text}, the text of the word
+to be dequoted, and @var{quote_char}, which is the quoting character 
+that delimits the filename (usually @samp{'} or @samp{"}).  If
+@var{quote_char} is zero, the filename was not in an embedded string.
+@end deftypevar
+
+@deftypevar {rl_linebuf_func_t *} rl_char_is_quoted_p
+A pointer to a function to call that determines whether or not a specific
+character in the line buffer is quoted, according to whatever quoting
+mechanism the program calling Readline uses.  The function is called with
+two arguments: @var{text}, the text of the line, and @var{index}, the
+index of the character in the line.  It is used to decide whether a
+character found in @code{rl_completer_word_break_characters} should be
+used to break words for the completer.
+@end deftypevar
+
+@deftypevar {rl_compignore_func_t *} rl_ignore_some_completions_function
+This function, if defined, is called by the completer when real filename
+completion is done, after all the matching names have been generated.
+It is passed a @code{NULL} terminated array of matches.
+The first element (@code{matches[0]}) is the
+maximal substring common to all matches. This function can
+re-arrange the list of matches as required, but each element deleted
+from the array must be freed.
+@end deftypevar
+
+@deftypevar {rl_icppfunc_t *} rl_directory_completion_hook
+This function, if defined, is allowed to modify the directory portion
+of filenames Readline completes.  It is called with the address of a
+string (the current directory name) as an argument, and may modify that string.
+If the string is replaced with a new string, the old value should be freed.
+Any modified directory name should have a trailing slash.
+The modified value will be displayed as part of the completion, replacing
+the directory portion of the pathname the user typed.
+It returns an integer that should be non-zero if the function modifies
+its directory argument.
+It could be used to expand symbolic links or shell variables in pathnames.
+At the least, even if no other expansion is performed, this function should
+remove any quote characters from the directory name, because its result will
+be passed directly to @code{opendir()}.
+@end deftypevar
+
+@ignore
+@deftypevar extern rl_icppfunc_t *rl_directory_rewrite_hook;
+If non-zero, this is the address of a function to call when completing
+a directory name.  This function takes the address of the directory name
+to be modified as an argument.  Unlike @code{rl_directory_completion_hook},
+it only modifies the directory name used in @code{opendir}, not what is
+displayed when the possible completions are printed or inserted.  It is
+called before rl_directory_completion_hook.
+
+I'm not happy with how this worksyet, so it's undocumented.
+@end deftypevar
+@end ignore
+
+@deftypevar {rl_dequote_func_t *} rl_filename_rewrite_hook
+If non-zero, this is the address of a function called when reading
+directory entries from the filesystem for completion and comparing
+them to the partial word to be completed.  The function should
+perform any necesary application or system-specific conversion on
+the filename, such as converting between character sets or converting
+from a filesystem format to a character input format.
+The function takes two arguments: @var{fname}, the filename to be converted,
+and @var{fnlen}, its length in bytes.
+It must either return its first argument (if no conversion takes place)
+or the converted filename in newly-allocated memory.  The converted
+form is used to compare against the word to be completed, and, if it
+matches, is added to the list of matches.  Readline will free the
+allocated string.
+@end deftypevar
+
+@deftypevar {rl_compdisp_func_t *} rl_completion_display_matches_hook
+If non-zero, then this is the address of a function to call when
+completing a word would normally display the list of possible matches.
+This function is called in lieu of Readline displaying the list.
+It takes three arguments:
+(@code{char **}@var{matches}, @code{int} @var{num_matches}, @code{int} @var{max_length})
+where @var{matches} is the array of matching strings,
+@var{num_matches} is the number of strings in that array, and
+@var{max_length} is the length of the longest string in that array.
+Readline provides a convenience function, @code{rl_display_match_list},
+that takes care of doing the display to Readline's output stream.  That
+function may be called from this hook.
+@end deftypevar
+
+@deftypevar {const char *} rl_basic_word_break_characters
+The basic list of characters that signal a break between words for the
+completer routine.  The default value of this variable is the characters
+which break words for completion in Bash:
+@code{" \t\n\"\\'`@@$><=;|&@{("}.
+@end deftypevar
+
+@deftypevar {const char *} rl_basic_quote_characters
+A list of quote characters which can cause a word break.
+@end deftypevar
+
+@deftypevar {const char *} rl_completer_word_break_characters
+The list of characters that signal a break between words for
+@code{rl_complete_internal()}.  The default list is the value of
+@code{rl_basic_word_break_characters}.
+@end deftypevar
+
+@deftypevar {rl_cpvfunc_t *} rl_completion_word_break_hook
+If non-zero, this is the address of a function to call when Readline is
+deciding where to separate words for word completion.  It should return
+a character string like @code{rl_completer_word_break_characters} to be
+used to perform the current completion.  The function may choose to set
+@code{rl_completer_word_break_characters} itself.  If the function
+returns @code{NULL}, @code{rl_completer_word_break_characters} is used.
+@end deftypevar
+
+@deftypevar {const char *} rl_completer_quote_characters
+A list of characters which can be used to quote a substring of the line.
+Completion occurs on the entire substring, and within the substring
+@code{rl_completer_word_break_characters} are treated as any other character,
+unless they also appear within this list.
+@end deftypevar
+
+@deftypevar {const char *} rl_filename_quote_characters
+A list of characters that cause a filename to be quoted by the completer
+when they appear in a completed filename.  The default is the null string.
+@end deftypevar
+
+@deftypevar {const char *} rl_special_prefixes
+The list of characters that are word break characters, but should be
+left in @var{text} when it is passed to the completion function.
+Programs can use this to help determine what kind of completing to do.
+For instance, Bash sets this variable to "$@@" so that it can complete
+shell variables and hostnames.
+@end deftypevar
+
+@deftypevar int rl_completion_query_items
+Up to this many items will be displayed in response to a
+possible-completions call.  After that, readline asks the user if she is sure
+she wants to see them all.  The default value is 100.  A negative value 
+indicates that Readline should never ask the user.
+@end deftypevar
+
+@deftypevar {int} rl_completion_append_character
+When a single completion alternative matches at the end of the command
+line, this character is appended to the inserted completion text.  The
+default is a space character (@samp{ }).  Setting this to the null
+character (@samp{\0}) prevents anything being appended automatically.
+This can be changed in application-specific completion functions to
+provide the ``most sensible word separator character'' according to
+an application-specific command line syntax specification.
+@end deftypevar
+
+@deftypevar int rl_completion_suppress_append
+If non-zero, @var{rl_completion_append_character} is not appended to
+matches at the end of the command line, as described above.
+It is set to 0 before any application-specific completion function
+is called, and may only be changed within such a function.
+@end deftypevar
+
+@deftypevar int rl_completion_quote_character
+When Readline is completing quoted text, as delimited by one of the
+characters in @var{rl_completer_quote_characters}, it sets this variable
+to the quoting character found.
+This is set before any application-specific completion function is called.
+@end deftypevar
+
+@deftypevar int rl_completion_suppress_quote
+If non-zero, Readline does not append a matching quote character when
+performing completion on a quoted string.
+It is set to 0 before any application-specific completion function
+is called, and may only be changed within such a function.
+@end deftypevar
+
+@deftypevar int rl_completion_found_quote
+When Readline is completing quoted text, it sets this variable
+to a non-zero value if the word being completed contains or is delimited
+by any quoting characters, including backslashes.
+This is set before any application-specific completion function is called.
+@end deftypevar
+
+@deftypevar int rl_completion_mark_symlink_dirs
+If non-zero, a slash will be appended to completed filenames that are
+symbolic links to directory names, subject to the value of the
+user-settable @var{mark-directories} variable.
+This variable exists so that application-specific completion functions
+can override the user's global preference (set via the
+@var{mark-symlinked-directories} Readline variable) if appropriate.
+This variable is set to the user's preference before any
+application-specific completion function is called, so unless that
+function modifies the value, the user's preferences are honored.
+@end deftypevar
+
+@deftypevar int rl_ignore_completion_duplicates
+If non-zero, then duplicates in the matches are removed.
+The default is 1.
+@end deftypevar
+
+@deftypevar int rl_filename_completion_desired
+Non-zero means that the results of the matches are to be treated as
+filenames.  This is @emph{always} zero when completion is attempted,
+and can only be changed
+within an application-specific completion function.  If it is set to a
+non-zero value by such a function, directory names have a slash appended
+and Readline attempts to quote completed filenames if they contain any
+characters in @code{rl_filename_quote_characters} and
+@code{rl_filename_quoting_desired} is set to a non-zero value.
+@end deftypevar
+
+@deftypevar int rl_filename_quoting_desired
+Non-zero means that the results of the matches are to be quoted using
+double quotes (or an application-specific quoting mechanism) if the
+completed filename contains any characters in
+@code{rl_filename_quote_chars}.  This is @emph{always} non-zero
+when completion is attempted, and can only be changed within an
+application-specific completion function.
+The quoting is effected via a call to the function pointed to
+by @code{rl_filename_quoting_function}.
+@end deftypevar
+
+@deftypevar int rl_attempted_completion_over
+If an application-specific completion function assigned to
+@code{rl_attempted_completion_function} sets this variable to a non-zero
+value, Readline will not perform its default filename completion even
+if the application's completion function returns no matches.
+It should be set only by an application's completion function.
+@end deftypevar
+
+@deftypevar int rl_sort_completion_matches
+If an application sets this variable to 0, Readline will not sort the
+list of completions (which implies that it cannot remove any duplicate
+completions).  The default value is 1, which means that Readline will
+sort the completions and, depending on the value of
+@code{rl_ignore_completion_duplicates}, will attempt to remove duplicate
+matches.
+@end deftypevar
+
+@deftypevar int rl_completion_type
+Set to a character describing the type of completion Readline is currently
+attempting; see the description of @code{rl_complete_internal()}
+(@pxref{Completion Functions}) for the list of characters.
+This is set to the appropriate value before any application-specific
+completion function is called, allowing such functions to present
+the same interface as @code{rl_complete()}.
+@end deftypevar
+
+@deftypevar int rl_completion_invoking_key
+Set to the final character in the key sequence that invoked one of the
+completion functions that call @code{rl_complete_internal()}.  This is
+set to the appropriate value before any application-specific completion
+function is called.
+@end deftypevar
+
+@deftypevar int rl_inhibit_completion
+If this variable is non-zero, completion is inhibited.  The completion
+character will be inserted as any other bound to @code{self-insert}.
