+with the GNU History Library.
+It should be considered a technical guide.
+For information on the interactive use of GNU History, @pxref{Using
+History Interactively}.

+@node Introduction to History
+@section Introduction to History
+
+Many programs read input from the user a line at a time.  The GNU History
+library is able to keep track of those lines, associate arbitrary data with
+each line, and utilize information from previous lines in composing new
+ones.
+
+The programmer using the History library has available functions
+for remembering lines on a history list, associating arbitrary data
+with a line, removing lines from the list, searching through the list
+for a line containing an arbitrary text string, and referencing any line
+in the list directly.  In addition, a history @dfn{expansion} function
+is available which provides for a consistent user interface across
+different programs.
+
+The user using programs written with the History library has the
+benefit of a consistent user interface with a set of well-known
+commands for manipulating the text of previous lines and using that text
+in new commands.  The basic history manipulation commands are similar to
+the history substitution provided by @code{csh}.
+
+If the programmer desires, he can use the Readline library, which
+includes some history manipulation by default, and has the added
+advantage of command line editing.
+
+@node History Storage
+@section History Storage
+
+The history list is an array of history entries.  A history entry is
+declared as follows:
+
+@example
+typedef struct _hist_entry @{
+  char *line;
+  char *data;
+@} HIST_ENTRY;
+@end example
+
+The history list itself might therefore be declared as
+
+@example
+HIST_ENTRY **the_history_list;
+@end example
+
+The state of the History library is encapsulated into a single structure:
+
+@example
+/* A structure used to pass the current state of the history stuff around. */
+typedef struct _hist_state @{
+  HIST_ENTRY **entries;         /* Pointer to the entries themselves. */
+  int offset;                   /* The location pointer within this array. */
+  int length;                   /* Number of elements within this array. */
+  int size;                     /* Number of slots allocated to this array. */
+  int flags;
+@} HISTORY_STATE;
+@end example
+
+If the flags member includes @code{HS_STIFLED}, the history has been
+stifled.
+
+@node History Functions
+@section History Functions
+
+This section describes the calling sequence for the various functions
+present in GNU History.
+
+@menu
+* Initializing History and State Management::	Functions to call when you
+						want to use history in a
+						program.
+* History List Management::		Functions used to manage the list
+					of history entries.
+* Information About the History List::	Functions returning information about
+					the history list.
+* Moving Around the History List::	Functions used to change the position
+					in the history list.
+* Searching the History List::		Functions to search the history list
+					for entries containing a string.
+* Managing the History File::		Functions that read and write a file
+					containing the history list.
+* History Expansion::			Functions to perform csh-like history
+					expansion.
+@end menu
+
+@node Initializing History and State Management
+@subsection Initializing History and State Management
+
+This section describes functions used to initialize and manage
+the state of the History library when you want to use the history
+functions in your program.
+
+@deftypefun void using_history ()
+Begin a session in which the history functions might be used.  This
+initializes the interactive variables.
+@end deftypefun
+
+@deftypefun {HISTORY_STATE *} history_get_history_state ()
+Return a structure describing the current state of the input history.
+@end deftypefun
+
+@deftypefun void history_set_history_state (HISTORY_STATE *state)
+Set the state of the history list according to @var{state}.
+@end deftypefun
+
+@node History List Management
+@subsection History List Management
+
+These functions manage individual entries on the history list, or set
+parameters managing the list itself.
+
+@deftypefun void add_history (char *string)
+Place @var{string} at the end of the history list.  The associated data
+field (if any) is set to @code{NULL}.
+@end deftypefun
+
+@deftypefun {HIST_ENTRY *} remove_history (int which)
+Remove history entry at offset @var{which} from the history.  The
+removed element is returned so you can free the line, data,
+and containing structure.
+@end deftypefun
+
+@deftypefun {HIST_ENTRY *} replace_history_entry (int which, char *line, char *data)
+Make the history entry at offset @var{which} have @var{line} and @var{data}.
+This returns the old entry so you can dispose of the data.  In the case
+of an invalid @var{which}, a @code{NULL} pointer is returned.
+@end deftypefun
+
+@deftypefun void clear_history ()
+Clear the history list by deleting all the entries.
+@end deftypefun
+
+@deftypefun void stifle_history (int max)
+Stifle the history list, remembering only the last @var{max} entries.
+@end deftypefun
+
+@deftypefun int unstifle_history ()
+Stop stifling the history.  This returns the previous amount the
+history was stifled.  The value is positive if the history was
+stifled, negative if it wasn't.
+@end deftypefun
+
+@deftypefun int history_is_stifled ()
+Returns non-zero if the history is stifled, zero if it is not.
+@end deftypefun
+
+@node Information About the History List
+@subsection Information About the History List
+
+These functions return information about the entire history list or
+individual list entries.
+
+@deftypefun {HIST_ENTRY **} history_list ()
+Return a @code{NULL} terminated array of @code{HIST_ENTRY} which is the
+current input history.  Element 0 of this list is the beginning of time.
+If there is no history, return @code{NULL}.
+@end deftypefun
+
+@deftypefun int where_history ()
+Returns the offset of the current history element.
+@end deftypefun
+
+@deftypefun {HIST_ENTRY *} current_history ()
+Return the history entry at the current position, as determined by
+@code{where_history ()}.  If there is no entry there, return a @code{NULL}
+pointer.
+@end deftypefun
+
+@deftypefun {HIST_ENTRY *} history_get (int offset)
+Return the history entry at position @var{offset}, starting from
+@code{history_base}.  If there is no entry there, or if @var{offset}
+is greater than the history length, return a @code{NULL} pointer.
+@end deftypefun
+
+@deftypefun int history_total_bytes ()
+Return the number of bytes that the primary history entries are using.
+This function returns the sum of the lengths of all the lines in the
+history.
+@end deftypefun
+
+@node Moving Around the History List
+@subsection Moving Around the History List
+
+These functions allow the current index into the history list to be
+set or changed.
+
+@deftypefun int history_set_pos (int pos)
+Set the position in the history list to @var{pos}, an absolute index
+into the list.
+@end deftypefun
+
+@deftypefun {HIST_ENTRY *} previous_history ()
+Back up the current history offset to the previous history entry, and
+return a pointer to that entry.  If there is no previous entry, return
+a @code{NULL} pointer.
+@end deftypefun
+
+@deftypefun {HIST_ENTRY *} next_history ()
+Move the current history offset forward to the next history entry, and
+return the a pointer to that entry.  If there is no next entry, return
+a @code{NULL} pointer.
+@end deftypefun
+
+@node Searching the History List
+@subsection Searching the History List
+@cindex History Searching
+
+These functions allow searching of the history list for entries containing
+a specific string.  Searching may be performed both forward and backward
+from the current history position.  The search may be @dfn{anchored},
+meaning that the string must match at the beginning of the history entry.
+@cindex anchored search
+
+@deftypefun int history_search (char *string, int direction)
+Search the history for @var{string}, starting at the current history
+offset.  If @var{direction} < 0, then the search is through previous entries,
+else through subsequent.  If @var{string} is found, then
+the current history index is set to that history entry, and the value
+returned is the offset in the line of the entry where
+@var{string} was found.  Otherwise, nothing is changed, and a -1 is
+returned.
+@end deftypefun
+
+@deftypefun int history_search_prefix (char *string, int direction)
+Search the history for @var{string}, starting at the current history
+offset.  The search is anchored: matching lines must begin with
+@var{string}.  If @var{direction} < 0, then the search is through previous
+entries, else through subsequent.  If @var{string} is found, then the
+current history index is set to that entry, and the return value is 0. 
+Otherwise, nothing is changed, and a -1 is returned. 
+@end deftypefun
+
+@deftypefun int history_search_pos (char *string, int direction, int pos)
+Search for @var{string} in the history list, starting at @var{pos}, an
+absolute index into the list.  If @var{direction} is negative, the search
+proceeds backward from @var{pos}, otherwise forward.  Returns the absolute
+index of the history element where @var{string} was found, or -1 otherwise.
+@end deftypefun
+
+@node Managing the History File
+@subsection Managing the History File
+
+The History library can read the history from and write it to a file.
+This section documents the functions for managing a history file.
+
+@deftypefun int read_history (char *filename)
+Add the contents of @var{filename} to the history list, a line at a
+time.  If @var{filename} is @code{NULL}, then read from
+@file{~/.history}.  Returns 0 if successful, or errno if not.
+@end deftypefun
+
+@deftypefun int read_history_range (char *filename, int from, int to)
+Read a range of lines from @var{filename}, adding them to the history list.
+Start reading at line @var{from} and end at @var{to}.  If
+@var{from} is zero, start at the beginning.  If @var{to} is less than
+@var{from}, then read until the end of the file.  If @var{filename} is
+@code{NULL}, then read from @file{~/.history}.  Returns 0 if successful,
+or @code{errno} if not.
+@end deftypefun
+
+@deftypefun int write_history (char *filename)
+Write the current history to @var{filename}, overwriting @var{filename}
+if necessary.  If @var{filename} is
+@code{NULL}, then write the history list to @file{~/.history}.  Values
+returned are as in @code{read_history ()}.
+@end deftypefun
+
+@deftypefun int append_history (int nelements, char *filename)
+Append the last @var{nelements} of the history list to @var{filename}.
+@end deftypefun
+
+@deftypefun int history_truncate_file (char *filename, int nlines)
+Truncate the history file @var{filename}, leaving only the last
+@var{nlines} lines.
+@end deftypefun
+
+@node History Expansion
+@subsection History Expansion
+
+These functions implement @code{csh}-like history expansion.
+
+@deftypefun int history_expand (char *string, char **output)
+Expand @var{string}, placing the result into @var{output}, a pointer
+to a string (@pxref{History Interaction}).  Returns:
+@table @code
+@item 0
+If no expansions took place (or, if the only change in
+the text was the de-slashifying of the history expansion
+character);
+@item 1
+if expansions did take place;
+@item -1
+if there was an error in expansion;
+@item 2
+if the returned line should only be displayed, but not executed,
+as with the @code{:p} modifier (@pxref{Modifiers}).
+@end table
+
+If an error ocurred in expansion, then @var{output} contains a descriptive
+error message.
+@end deftypefun
+
+@deftypefun {char *} history_arg_extract (int first, int last, char *string)
+Extract a string segment consisting of the @var{first} through @var{last}
+arguments present in @var{string}.  Arguments are broken up as in Bash.
+@end deftypefun
+
+@deftypefun {char *} get_history_event (char *string, int *cindex, int qchar)
+Returns the text of the history event beginning at @var{string} +
+@var{*cindex}.  @var{*cindex} is modified to point to after the event
+specifier.  At function entry, @var{cindex} points to the index into
+@var{string} where the history event specification begins.  @var{qchar}
+is a character that is allowed to end the event specification in addition
+to the ``normal'' terminating characters.
+@end deftypefun
+
+@deftypefun {char **} history_tokenize (char *string)
+Return an array of tokens parsed out of @var{string}, much as the
+shell might.  The tokens are split on white space and on the
+characters @code{()<>;&|$}, and shell quoting conventions are
+obeyed.
+@end deftypefun
+
+@node History Variables
+@section History Variables
+
+This section describes the externally visible variables exported by
+the GNU History Library.
+
+@deftypevar int history_base
+The logical offset of the first entry in the history list.
+@end deftypevar
+
+@deftypevar int history_length
+The number of entries currently stored in the history list.
+@end deftypevar
+
+@deftypevar int max_input_history
+The maximum number of history entries.  This must be changed using
+@code{stifle_history ()}.
+@end deftypevar
+
+@deftypevar char history_expansion_char
+The character that starts a history event.  The default is @samp{!}.
+@end deftypevar
+
+@deftypevar char history_subst_char
+The character that invokes word substitution if found at the start of
+a line.  The default is @samp{^}.
+@end deftypevar
+
+@deftypevar char history_comment_char
+During tokenization, if this character is seen as the first character
+of a word, then it and all subsequent characters up to a newline are
+ignored, suppressing history expansion for the remainder of the line.
+This is disabled by default.
+@end deftypevar
+
+@deftypevar {char *} history_no_expand_chars
+The list of characters which inhibit history expansion if found immediately
+following @var{history_expansion_char}.  The default is whitespace and
+@samp{=}.
+@end deftypevar
+
+@deftypevar {char *} history_search_delimiter_chars
+The list of additional characters which can delimit a history search
+string, in addition to whitespace, @samp{:} and @samp{?} in the case of
+a substring search.  The default is empty.
+@end deftypevar
+
+@deftypevar int history_quotes_inhibit_expansion
+If non-zero, single-quoted words are not scanned for the history expansion
+character.  The default value is 0.
+@end deftypevar
+
+@deftypevar {Function *} history_inhibit_expansion_function
+This should be set to the address of a function that takes two arguments:
+a @code{char *} (@var{string}) and an integer index into that string (@var{i}).
+It should return a non-zero value if the history expansion starting at
+@var{string[i]} should not be performed; zero if the expansion should

+It is intended for use by applications like Bash that use the history
+expansion character for additional purposes.
+By default, this variable is set to NULL.

+@cindex command history
+@cindex history list
+
+When the @samp{-o history} option to the @code{set} builtin
+is enabled (@pxref{The Set Builtin}),
+the shell provides access to the @var{command history},
+the list of commands previously typed.  The text of the last
+@code{HISTSIZE}
+commands (default 500) is saved in a history list.  The shell
+stores each command in the history list prior to parameter and
+variable expansion
+but after history expansion is performed, subject to the
+values of the shell variables
+@code{HISTIGNORE} and @code{HISTCONTROL}.
+When the shell starts up, the history is initialized from the
+file named by the @code{HISTFILE} variable (default @file{~/.bash_history}).
+@code{HISTFILE} is truncated, if necessary, to contain no more than
+the number of lines specified by the value of the @code{HISTFILESIZE}
+variable.  When an interactive shell exits, the last
+@code{HISTSIZE} lines are copied from the history list to @code{HISTFILE}.
+If the @code{histappend} shell option is set (@pxref{Bash Builtins}),
+the lines are appended to the history file,
+otherwise the history file is overwritten.
+If @code{HISTFILE}
+is unset, or if the history file is unwritable, the history is
+not saved.  After saving the history, the history file is truncated
+to contain no more than @code{$HISTFILESIZE}
+lines.  If @code{HISTFILESIZE} is not set, no truncation is performed.
+
+The builtin command @code{fc} may be used to list or edit and re-execute
+a portion of the history list.
+The @code{history} builtin can be used to display or modify the history
+list and manipulate the history file.
+When using the command-line editing, search commands
+are available in each editing mode that provide access to the
+history list.
+
+The shell allows control over which commands are saved on the history
+list.  The @code{HISTCONTROL} and @code{HISTIGNORE}
+variables may be set to cause the shell to save only a subset of the
+commands entered.
+The @code{cmdhist}
+shell option, if enabled, causes the shell to attempt to save each
+line of a multi-line command in the same history entry, adding
+semicolons where necessary to preserve syntactic correctness.
+The @code{lithist}
+shell option causes the shell to save the command with embedded newlines
+instead of semicolons.

+@node Bash History Builtins
+@section Bash History Builtins
+@cindex history builtins
+
+Bash provides two builtin commands that allow you to manipulate the
+history list and history file.
+
+@table @code
+
+@item fc
+@comment btindex fc
+@example
+@code{fc [-e @var{ename}] [-nlr] [@var{first}] [@var{last}]}
+@code{fc -s [@var{pat}=@var{rep}] [@var{command}]}
+@end example
+
+Fix Command.  In the first form, a range of commands from @var{first} to
+@var{last} is selected from the history list.  Both @var{first} and
+@var{last} may be specified as a string (to locate the most recent
+command beginning with that string) or as a number (an index into the
+history list, where a negative number is used as an offset from the
+current command number).  If @var{last} is not specified it is set to
+@var{first}.  If @var{first} is not specified it is set to the previous
+command for editing and @minus{}16 for listing.  If the @samp{-l} flag is
+given, the commands are listed on standard output.  The @samp{-n} flag
+suppresses the command numbers when listing.  The @samp{-r} flag
+reverses the order of the listing.  Otherwise, the editor given by
+@var{ename} is invoked on a file containing those commands.  If
+@var{ename} is not given, the value of the following variable expansion
+is used: @code{$@{FCEDIT:-$@{EDITOR:-vi@}@}}.  This says to use the
+value of the @code{FCEDIT} variable if set, or the value of the
+@code{EDITOR} variable if that is set, or @code{vi} if neither is set.
+When editing is complete, the edited commands are echoed and executed.
+
+In the second form, @var{command} is re-executed after each instance
+of @var{pat} in the selected command is replaced by @var{rep}.
+
+A useful alias to use with the @code{fc} command is @code{r='fc -s'}, so
+that typing @samp{r cc} runs the last command beginning with @code{cc}
+and typing @samp{r} re-executes the last command (@pxref{Aliases}).
+
+@item history
+@comment btindex history
+@example
+history [-c] [@var{n}]
+history [-anrw] [@var{filename}]
+history -ps @var{arg}
+@end example
+
+Display the history list with line numbers.  Lines prefixed with
+with a @samp{*} have been modified.  An argument of @var{n} says
+to list only the last @var{n} lines.  Options, if supplied, have
+the following meanings:
+
+@table @code
+@item -w
+Write out the current history to the history file.
+
+@item -r
+Read the current history file and append its contents to
+the history list.
+
+@item -a
+Append the new
+history lines (history lines entered since the beginning of the
+current Bash session) to the history file.
+
+@item -n
+Append the history lines not already read from the history file
+to the current history list.  These are lines appended to the history
+file since the beginning of the current Bash session.
+
+@item -c
+Clear the history list.  This may be combined
+with the other options to replace the history list completely.
+
+@item -s
+The @var{arg}s are added to the end of
+the history list as a single entry.
+
+@item -p
+Perform history substitution on the @var{arg}s and display the result
+on the standard output, without storing the results in the history list.
+@end table
+
+When the @samp{-w}, @samp{-r}, @samp{-a}, or @samp{-n} option is
+used, if @var{filename}
+is given, then it is used as the history file.  If not, then
+the value of the @code{HISTFILE} variable is used.
+
+@end table
+@end ifset
+
+@node History Interaction
+@section History Expansion
+@cindex history expansion
+
+The History library provides a history expansion feature that is similar
+to the history expansion provided by @code{csh}.  This section
+describes the syntax used to manipulate the history information.
+
+History expansions introduce words from the history list into
+the input stream, making it easy to repeat commands, insert the
+arguments to a previous command into the current input line, or
+fix errors in previous commands quickly.
+
+History expansion takes place in two parts.  The first is to determine
+which line from the history list should be used during substitution.
+The second is to select portions of that line for inclusion into the
+current one.  The line selected from the history is called the
+@dfn{event}, and the portions of that line that are acted upon are
+called @dfn{words}.  Various @dfn{modifiers} are available to manipulate
+the selected words.  The line is broken into words in the same fashion
+that Bash does, so that several words
+surrounded by quotes are considered one word.
+History expansions are introduced by the appearance of the
+history expansion character, which is @samp{!} by default.
+@ifset BashFeatures
+Only @samp{\} and @samp{'} may be used to escape the history expansion
+character.
+@end ifset
+
+@ifset BashFeatures
+Several shell options settable with the @code{shopt}
+builtin (@pxref{Bash Builtins}) may be used to tailor
+the behavior of history expansion.  If the
+@code{histverify} shell option is enabled, and Readline
+is being used, history substitutions are not immediately passed to
+the shell parser.
+Instead, the expanded line is reloaded into the Readline
+editing buffer for further modification.
+If Readline is being used, and the @code{histreedit}
+shell option is enabled, a failed history expansion will be
+reloaded into the Readline editing buffer for correction.
+The @samp{-p} option to the @code{history} builtin command
+may be used to see what a history expansion will do before using it.
+The @samp{-s} option to the @code{history} builtin may be used to
+add commands to the end of the history list without actually executing
+them, so that they are available for subsequent recall.
+This is most useful in conjunction with Readline.
+
+The shell allows control of the various characters used by the
+history expansion mechanism with the @code{histchars} variable.

+
+@node Event Designators
+@subsection Event Designators
+@cindex event designators
+
+An event designator is a reference to a command line entry in the
+history list.
+@cindex history events
+
+@table @asis
+
+@item @code{!}
+Start a history substitution, except when followed by a space, tab,
+the end of the line, @samp{=} or @samp{(}.
+
+@item @code{!@var{n}}
+Refer to command line @var{n}.
+
+@item @code{!-@var{n}}
+Refer to the command @var{n} lines back.
+
+@item @code{!!}
+Refer to the previous command.  This is a synonym for @samp{!-1}.
+
+@item @code{!@var{string}}
+Refer to the most recent command starting with @var{string}.
+
+@item @code{!?@var{string}[?]}
+Refer to the most recent command containing @var{string}.  The trailing
+@samp{?} may be omitted if the @var{string} is followed immediately by
+a newline.
+
+@item @code{^@var{string1}^@var{string2}^}
+Quick Substitution.  Repeat the last command, replacing @var{string1}
+with @var{string2}.  Equivalent to
+@code{!!:s/@var{string1}/@var{string2}/}.
+
+@item @code{!#}
+The entire command line typed so far.
+
+@end table
+
+@node Word Designators
+@subsection Word Designators
+
+Word designators are used to select desired words from the event.
+A @samp{:} separates the event specification from the word designator.  It
+may be omitted if the word designator begins with a @samp{^}, @samp{$},
+@samp{*}, @samp{-}, or @samp{%}.  Words are numbered from the beginning
+of the line, with the first word being denoted by 0 (zero).  Words are
+inserted into the current line separated by single spaces.
+
+@table @code
+
+@item 0 (zero)
+The @code{0}th word.  For many applications, this is the command word.
+
+@item @var{n}
+The @var{n}th word.
+
+@item ^
+The first argument; that is, word 1.
+
+@item $
+The last argument.
+
+@item %
+The word matched by the most recent @samp{?@var{string}?} search.
+
+@item @var{x}-@var{y}
+A range of words; @samp{-@var{y}} abbreviates @samp{0-@var{y}}.
+
+@item *
+All of the words, except the @code{0}th.  This is a synonym for @samp{1-$}.
+It is not an error to use @samp{*} if there is just one word in the event;
+the empty string is returned in that case.
+
+@item @var{x}*
+Abbreviates @samp{@var{x}-$}
+
+@item @var{x}-
+Abbreviates @samp{@var{x}-$} like @samp{@var{x}*}, but omits the last word.
+
+@end table
+
+If a word designator is supplied without an event specification, the
+previous command is used as the event.
+
+@node Modifiers
+@subsection Modifiers
+
+After the optional word designator, you can add a sequence of one or more
+of the following modifiers, each preceded by a @samp{:}.
+
+@table @code
+
+@item h
+Remove a trailing pathname component, leaving only the head.
+
+@item t
+Remove all leading  pathname  components, leaving the tail.
+
+@item r
+Remove a trailing suffix of the form @samp{.@var{suffix}}, leaving
+the basename.
+
+@item e
+Remove all but the trailing suffix.
+
+@item p
+Print the new command but do not execute it.
+
+@ifset BashFeatures
+@item q
+Quote the substituted words, escaping further substitutions.
+
+@item x
+Quote the substituted words as with @samp{q},
+but break into words at spaces, tabs, and newlines.
+@end ifset
+
+@item s/@var{old}/@var{new}/
+Substitute @var{new} for the first occurrence of @var{old} in the
+event line.  Any delimiter may be used in place of @samp{/}.
+The delimiter may be quoted in @var{old} and @var{new}
+with a single backslash.  If @samp{&} appears in @var{new},
+it is replaced by @var{old}.  A single backslash will quote
+the @samp{&}.  The final delimiter is optional if it is the last
+character on the input line.
+
+@item &
+Repeat the previous substitution.
+
+@item g
+Cause changes to be applied over the entire event line.  Used in
+conjunction with @samp{s}, as in @code{gs/@var{old}/@var{new}/},
+or with @samp{&}.

+.SH DESCRIPTION
+.LP
+.B readline
+will read a line from the terminal
+and return it, using
+.B prompt
+as a prompt.  If 
+.B prompt
+is null, no prompt is issued.  The line returned is allocated with
+.IR malloc (3),
+so the caller must free it when finished.  The line returned
+has the final newline removed, so only the text of the line
+remains.
+.LP
+.B readline
+offers editing capabilities while the user is entering the
+line.
+By default, the line editing commands
+are similar to those of emacs.
+A vi\-style line editing interface is also available.
+.SH RETURN VALUE
+.LP
+.B readline
+returns the text of the line read.  A blank line
+returns the empty string.  If
+.B EOF
+is encountered while reading a line, and the line is empty,
+.B NULL
+is returned.  If an
+.B EOF
+is read with a non\-empty line, it is
+treated as a newline.
+.SH NOTATION
+.LP
+An emacs-style notation is used to denote
+keystrokes.  Control keys are denoted by C\-\fIkey\fR, e.g., C\-n
+means Control\-N.  Similarly, 
+.I meta
+keys are denoted by M\-\fIkey\fR, so M\-x means Meta\-X.  (On keyboards
+without a 
+.I meta
+key, M\-\fIx\fP means ESC \fIx\fP, i.e., press the Escape key
+then the
+.I x
+key.  This makes ESC the \fImeta prefix\fP.
+The combination M\-C\-\fIx\fP means ESC\-Control\-\fIx\fP,
+or press the Escape key
+then hold the Control key while pressing the
+.I x
+key.)
+.PP
+Readline commands may be given numeric
+.IR arguments ,
+which normally act as a repeat count.  Sometimes, however, it is the
+sign of the argument that is significant.  Passing a negative argument
+to a command that acts in the forward direction (e.g., \fBkill\-line\fP)
+causes that command to act in a backward direction.  Commands whose
+behavior with arguments deviates from this are noted.
+.PP
+When a command is described as \fIkilling\fP text, the text
+deleted is saved for possible future retrieval
+(\fIyanking\fP).  The killed text is saved in a
+\fIkill ring\fP.  Consecutive kills cause the text to be
+accumulated into one unit, which can be yanked all at once. 
+Commands which do not kill text separate the chunks of text
+on the kill ring.
+.SH INITIALIZATION FILE
+.LP
+Readline is customized by putting commands in an initialization
+file (the \fIinputrc\fP file).
+The name of this file is taken from the value of the
+.B INPUTRC
+environment variable.  If that variable is unset, the default is
+.IR ~/.inputrc .
+When a program which uses the readline library starts up, the
+init file is read, and the key bindings and variables are set.
+There are only a few basic constructs allowed in the
+readline init file.  Blank lines are ignored.
+Lines beginning with a \fB#\fP are comments.
+Lines beginning with a \fB$\fP indicate conditional constructs.
+Other lines denote key bindings and variable settings.
+Each program using this library may add its own commands
+and bindings.
+.PP
+For example, placing
+.RS
+.PP
+M\-Control\-u: universal\-argument
+.RE
+or
+.RS
+C\-Meta\-u: universal\-argument
+.RE
+into the 
+.I inputrc
+would make M\-C\-u execute the readline command
+.IR universal\-argument .
+.PP
+The following symbolic character names are recognized while
+processing key bindings:
+.IR RUBOUT ,
+.IR DEL ,
+.IR ESC ,
+.IR LFD ,
+.IR NEWLINE ,
+.IR RET ,
+.IR RETURN ,
+.IR SPC ,
+.IR SPACE ,
+and
+.IR TAB .
+In addition to command names, readline allows keys to be bound
+to a string that is inserted when the key is pressed (a \fImacro\fP).
+.PP
+.SS Key Bindings
+.PP
+The syntax for controlling key bindings in the
+.I inputrc
+file is simple.  All that is required is the name of the
+command or the text of a macro and a key sequence to which
+it should be bound. The name may be specified in one of two ways:
+as a symbolic key name, possibly with \fIMeta\-\fP or \fIControl\-\fP
+prefixes, or as a key sequence.
+When using the form \fBkeyname\fP:\^\fIfunction-name\fP or \fImacro\fP,
+.I keyname
+is the name of a key spelled out in English.  For example:
+.sp
+.RS
+Control\-u: universal\-argument
+.br
+Meta\-Rubout: backward\-kill\-word
+.br
+Control\-o: ">&output"
+.RE
+.LP
+In the above example,
+.I C\-u
+is bound to the function
+.BR universal\-argument ,
+.I M-DEL
+is bound to the function
+.BR backward\-kill\-word ,
+and
+.I C\-o
+is bound to run the macro
+expressed on the right hand side (that is, to insert the text
+.I >&output
+into the line).
+.PP
+In the second form, \fB"keyseq"\fP:\^\fIfunction\-name\fP or \fImacro\fP,
+.B keyseq
+differs from
+.B keyname
+above in that strings denoting
+an entire key sequence may be specified by placing the sequence
+within double quotes.  Some GNU Emacs style key escapes can be
+used, as in the following example.
+.sp
+.RS
+"\eC\-u": universal\-argument
+.br

+.I inputrc
+file with a statement of the form
+.RS
+.PP
+\fBset\fP \fIvariable\-name\fP \fIvalue\fP
+.RE
+.PP
+Except where noted, readline variables can take the values
+.B On
+or
+.BR Off .
+The variables and their default values are:
+.PP
+.PD 0
+.TP
+.B bell\-style (audible)
+Controls what happens when readline wants to ring the terminal bell.
+If set to \fBnone\fP, readline never rings the bell.  If set to
+\fBvisible\fP, readline uses a visible bell if one is available.
+If set to \fBaudible\fP, readline attempts to ring the terminal's bell.
+.TP
+.B comment\-begin (``#'')
+The string that is inserted in \fBvi\fP mode when the
+.B insert\-comment
+command is executed.
+This command is bound to
+.B M\-#
+in emacs mode and to
+.B #
+in vi command mode.
+.TP 
+.B completion\-ignore\-case (Off)
+If set to \fBOn\fP, readline performs filename matching and completion
+in a case\-insensitive fashion.
+.TP
+.B completion\-query\-items (100)
+This determines when the user is queried about viewing
+the number of possible completions
+generated by the \fBpossible\-completions\fP command.
+It may be set to any integer value greater than or equal to
+zero.  If the number of possible completions is greater than
+or equal to the value of this variable, the user is asked whether
+or not he wishes to view them; otherwise they are simply listed
+on the terminal.
+.TP
+.B convert\-meta (On)
+If set to \fBOn\fP, readline will convert characters with the
+eighth bit set to an ASCII key sequence
+by stripping the eighth bit and prepending an
+escape character (in effect, using escape as the \fImeta prefix\fP).
+.TP
+.B disable\-completion (Off)
+If set to \fBOn\fP, readline will inhibit word completion.  Completion 
+characters will be inserted into the line as if they had been
+mapped to \fBself-insert\fP.
+.TP
+.B editing\-mode (emacs)
+Controls whether readline begins with a set of key bindings similar
+to \fIemacs\fP or \fIvi\fP.
+.B editing\-mode
+can be set to either
+.B emacs
+or
+.BR vi .
+.TP
+.B enable\-keypad (Off)
+When set to \fBOn\fP, readline will try to enable the application
+keypad when it is called.  Some systems need this to enable the
+arrow keys.
+.TP
+.B expand\-tilde (Off)
+If set to \fBon\fP, tilde expansion is performed when readline
+attempts word completion.
+.TP
+.B horizontal\-scroll\-mode (Off)
+When set to \fBOn\fP, makes readline use a single line for display,
+scrolling the input horizontally on a single screen line when it
+becomes longer than the screen width rather than wrapping to a new line.
+.TP
+.B keymap (emacs)
+Set the current readline keymap.  The set of legal keymap names is
+\fIemacs, emacs-standard, emacs-meta, emacs-ctlx, vi, vi-move,
+vi-command\fP, and
+.IR vi-insert .
+\fIvi\fP is equivalent to \fIvi-command\fP; \fIemacs\fP is
+equivalent to \fIemacs-standard\fP.  The default value is
+.IR emacs ;
+the value of
+.B editing\-mode
+also affects the default keymap.
+.TP
+.B mark\-directories (On)
+If set to \fBOn\fP, complete<d directory names have a slash
+appended.
+.TP
+.B mark\-modified\-lines (Off)
+If set to \fBOn\fP, history lines that have been modified are displayed
+with a preceding asterisk (\fB*\fP).
+.TP
+.B meta\-flag (Off)
+If set to \fBOn\fP, readline will enable eight-bit input (that is,
+it will not strip the high bit from the characters it reads),
+regardless of what the terminal claims it can support.
+.TP
+.B output\-meta (Off)
+If set to \fBOn\fP, readline will display characters with the
+eighth bit set directly rather than as a meta-prefixed escape
+sequence.
+.TP
+.B print\-completions\-horizontally (Off)
+If set to \fBOn\fP, readline will display completions with matches
+sorted horizontally in alphabetical order, rather than down the screen.
+.TP
+.B show\-all\-if\-ambiguous (Off)
+This alters the default behavior of the completion functions.  If
+set to
+.BR on ,
+words which have more than one possible completion cause the
+matches to be listed immediately instead of ringing the bell.
+.TP
+.B visible\-stats (Off)
+If set to \fBOn\fP, a character denoting a file's type as reported  
+by \fBstat\fP(2) is appended to the filename when listing possible
+completions.
+.PD
+.SS Conditional Constructs
+.PP
+Readline implements a facility similar in spirit to the conditional
+compilation features of the C preprocessor which allows key
+bindings and variable settings to be performed as the result
+of tests.  There are four parser directives used.
+.IP \fB$if\fP
+The 
+.B $if
+construct allows bindings to be made based on the
+editing mode, the terminal being used, or the application using
+readline.  The text of the test extends to the end of the line;
+no characters are required to isolate it.
+.RS
+.IP \fBmode\fP
+The \fBmode=\fP form of the \fB$if\fP directive is used to test
+whether readline is in emacs or vi mode.
+This may be used in conjunction
+with the \fBset keymap\fP command, for instance, to set bindings in
+the \fIemacs-standard\fP and \fIemacs-ctlx\fP keymaps only if
+readline is starting out in emacs mode.
+.IP \fBterm\fP
+The \fBterm=\fP form may be used to include terminal-specific
+key bindings, perhaps to bind the key sequences output by the
+terminal's function keys.  The word on the right side of the
+.B =
+is tested against the full name of the terminal and the portion
+of the terminal name before the first \fB\-\fP.  This allows
+.I sun
+to match both
+.I sun
+and
+.IR sun\-cmd ,
+for instance.
+.IP \fBapplication\fP
+The \fBapplication\fP construct is used to include
+application-specific settings.  Each program using the readline
+library sets the \fIapplication name\fP, and an initialization
+file can test for a particular value.
+This could be used to bind key sequences to functions useful for
+a specific program.  For instance, the following command adds a
+key sequence that quotes the current or previous word in Bash:
+.sp 1
+.RS
+.nf
+\fB$if\fP bash
+# Quote the current or previous word
+"\eC-xq": "\eeb\e"\eef\e""
+\fB$endif\fP
+.fi
+.RE
+.RE
+.IP \fB$endif\fP
+This command, as seen in the previous example, terminates an
+\fB$if\fP command.
+.IP \fB$else\fP
+Commands in this branch of the \fB$if\fP directive are executed if
+the test fails.
+.IP \fB$include\fP
+This directive takes a single filename as an argument and reads commands
+and bindings from that file.  For example, the following directive
+would read \fI/etc/inputrc\fP:
+.sp 1
+.RS
+.nf
+\fB$include\fP \^ \fI/etc/inputrc\fP
+.fi 
+.RE
+.SH SEARCHING
+.PP
+Readline provides commands for searching through the command history
+for lines containing a specified string.
+There are two search modes:
+.I incremental
+and
+.IR non-incremental .
+.PP
+Incremental searches begin before the user has finished typing the
+search string.
+As each character of the search string is typed, readline displays
+the next entry from the history matching the string typed so far.
+An incremental search requires only as many characters as needed to
+find the desired history entry.
+The Escape character is used to terminate an incremental search.
+Control-J will also terminate the search.
+Control-G will abort an incremental search and restore the original
+line.
+When the search is terminated, the history entry containing the
+search string becomes the current line.
+To find other matching entries in the history list, type Control-S or
+Control-R as appropriate.
+This will search backward or forward in the history for the next
+line matching the search string typed so far.
+Any other key sequence bound to a readline command will terminate
+the search and execute that command.
+For instance, a \fInewline\fP will terminate the search and accept
+the line, thereby executing the command from the history list.
+.PP
+Non-incremental searches read the entire search string before starting
+to search for matching history lines.  The search string may be
+typed by the user or be part of the contents of the current line.
+.SH EDITING COMMANDS
+.PP
+The following is a list of the names of the commands and the default
+key sequences to which they are bound.
+Command names without an accompanying key sequence are unbound by default.

+.PD
+.SS Numeric Arguments
+.PP
+.PD 0
+.TP
+.B digit\-argument (M\-0, M\-1, ..., M\-\-)
+Add this digit to the argument already accumulating, or start a new
+argument.  M\-\- starts a negative argument.
+.TP
+.B universal\-argument
+This is another way to specify an argument.
+If this command is followed by one or more digits, optionally with a
+leading minus sign, those digits define the argument.
+If the command is followed by digits, executing
+.B universal\-argument
+again ends the numeric argument, but is otherwise ignored.
+As a special case, if this command is immediately followed by a
+character that is neither a digit or minus sign, the argument count
+for the next command is multiplied by four.
+The argument count is initially one, so executing this function the
+first time makes the argument count four, a second time makes the
+argument count sixteen, and so on.
+.PD
+.SS Completing
+.PP
+.PD 0
+.TP
+.B complete (TAB)
+Attempt to perform completion on the text before point.

+.TP
+.B menu\-complete
+Similar to \fBcomplete\fP, but replaces the word to be completed
+with a single match from the list of possible completions.
+Repeated execution of \fBmenu\-complete\fP steps through the list
+of possible completions, inserting each match in turn.
+At the end of the list of completions, the bell is rung and the
+original text is restored.
+An argument of \fIn\fP moves \fIn\fP positions forward in the list

+@node Programming with GNU Readline
+@chapter Programming with GNU Readline
+
+This chapter describes the interface between the GNU Readline Library and
+other programs.  If you are a programmer, and you wish to include the
+features found in 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 Completers::	Supplanting or supplementing Readline's
+			completion functions.
+@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 and then reads and returns
+a single line of text from the user.  The line @code{readline}
+returns is allocated with @code{malloc ()}; you should @code{free ()}
+the line when you are done with it.  The declaration for @code{readline}
+in ANSI C is
+
+@example
+@code{char *readline (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}, int (*@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.
+
+@menu
+* The Function Type::	C declarations to make code readable.
+* Function Writing::	Variables and calling conventions.
+@end menu
+
+@node The Function Type
+@subsection The Function Type
+
+For readabilty, we declare a new type of object, called
+@dfn{Function}.  A @code{Function} is a C function which
+returns an @code{int}.  The type declaration for @code{Function} is:
+
+@noindent
+@code{typedef int Function ();}
+
+The reason for declaring this new type is to make it easier to write
+code describing pointers to C functions.  Let us say we had a variable
+called @var{func} which was a pointer to a function.  Instead of the
+classic C declaration
+
+@code{int (*)()func;}
+
+@noindent
+we may write
+
+@code{Function *func;}
+
+@noindent
+Similarly, there are
+
+@example
+typedef void VFunction ();
+typedef char *CPFunction (); @r{and}
+typedef char **CPPFunction ();
+@end example
+
+@noindent
+for functions returning no value, @code{pointer to char}, and
+@code{pointer to pointer to char}, respectively.
+
+@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{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.
+
+@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}.
+@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 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_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 {char *} rl_prompt
+The prompt Readline uses.  This is set from the argument to
+@code{readline ()}, and should not be assigned to directly.
+@end deftypevar
+
+@deftypevar {char *} rl_library_version
+The version number of this revision of the library.
+@end deftypevar
+
+@deftypevar {char *} rl_terminal_name
+The terminal type, used for initialization.
+@end deftypevar
+
+@deftypevar {char *} rl_readline_name
+This variable is set to a unique name by each application using Readline.
+The value allows conditional parsing of the inputrc file
+(@pxref{Conditional Init Constructs}).
+@end deftypevar
+
+@deftypevar {FILE *} rl_instream
+The stdio stream from which Readline reads input.
+@end deftypevar
+
+@deftypevar {FILE *} rl_outstream
+The stdio stream to which Readline performs output.
+@end deftypevar
+
+@deftypevar {Function *} rl_startup_hook
+If non-zero, this is the address of a function to call just
+before @code{readline} prints the first prompt.
+@end deftypevar
+
+@deftypevar {Function *} rl_event_hook
+If non-zero, this is the address of a function to call periodically
+when readline is waiting for terminal input.
+@end deftypevar
+
+@deftypevar {Function *} rl_getc_function
+If non-zero, @code{readline} will call indirectly through this pointer
+to get a character from the input stream.  By default, it is set to
+@code{rl_getc}, the default @code{readline} character input function
+(@pxref{Utility Functions}).
+@end deftypevar
+
+@deftypevar {VFunction *} rl_redisplay_function
+If non-zero, @code{readline} will call indirectly through this pointer
+to update the display with the current contents of the editing buffer.
+By default, it is set to @code{rl_redisplay}, the default @code{readline}
+redisplay function (@pxref{Redisplay}).
+@end deftypevar
+
+@deftypevar {Keymap} rl_executing_keymap
+This variable is set to the keymap (@pxref{Keymaps}) in which the
+currently executing readline function was found.
+@end deftypevar

+@deftypevar {Keymap} rl_binding_keymap
+This variable is set to the keymap (@pxref{Keymaps}) in which the

+@end menu
+
+@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 (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 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 ()
+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 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 ()
+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 @var{keymap}.
+@end deftypefun
+
+Readline has several internal keymaps.  These functions allow you to
+change which keymap is active.
+
+@deftypefun Keymap rl_get_keymap ()
+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 (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)

+@subsection Binding Keys

+@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.
+
+These functions manage key bindings.
+
+@deftypefun int rl_bind_key (int key, Function *function)

+@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.  I could use an undo function for
+the stock market.
+
+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:
+
+@example
+enum undo_code @{ UNDO_DELETE, UNDO_INSERT, UNDO_BEGIN, UNDO_END @}; 
+@end example
+
+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 undo 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 ()
+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 ()
+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 free_undo_list ()
+Free the existing undo list.
+@end deftypefun
+
+@deftypefun int rl_do_undo ()
+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)

+that text.

+
+@deftypefun void rl_callback_read_char ()
+Whenever an application determines that keyboard input is available, it
+should call @code{rl_callback_read_char()}, which will read the next

+@node Custom Completers
+@section Custom Completers
+
+Typically, a program that reads commands from the user has a way of

+@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 Readline
+functions intended for interactive use:  @var{count} and
+@var{invoking_key}.  It isolates the word to be completed and calls
+@code{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{completion_matches ()} uses your
+@dfn{generator} function to generate the list of possible matches, and
+then returns the array of these matches.  You should place the address
+of your generator function in @code{rl_completion_entry_function}.
+
+@item
+The generator function is called repeatedly from
+@code{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.  When the generator function returns
+@code{(char *)NULL} this signals @code{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.
+
+@end enumerate
+
+@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{completion_matches ()}).  The default is to do filename completion.
+@end deftypefun
+
+@deftypevar {Function *} rl_completion_entry_function
+This is a pointer to the generator function for @code{completion_matches
+()}.  If the value of @code{rl_completion_entry_function} is
+@code{(Function *)NULL} then the default filename generator function,
+@code{filename_completion_function ()}, is used.
+@end deftypevar
+
+@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.
+@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{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 {char **} completion_matches (char *text, CPFunction *entry_func)
+Returns an array of @code{(char *)} which is a list of completions for
+@var{text}.  If there are no completions, returns @code{(char **)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 *} filename_completion_function (char *text, int state)
+A generator function for filename completion in the general case.  Note
+that completion in Bash is a little different because of all
+the pathnames that must be followed when looking up completions for a
+command.  The Bash source is a useful reference for writing custom
+completion functions.
+@end deftypefun
+
+@deftypefun {char *} username_completion_function (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 {Function *} rl_completion_entry_function

+@code{NULL} means to use @code{filename_entry_function ()}, the default
+filename completer.
+@end deftypevar
+
+@deftypevar {CPPFunction *} 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} saying
+what the boundaries of @var{text} are.  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.
+@end deftypevar
+
+@deftypevar {CPFunction *} 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 {CPFunction *} 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 {Function *} 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

+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_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 custom completion functions to
+provide the ``most sensible word separator character'' according to
+an application-specific command line syntax specification.
+@end deftypevar
+
+@deftypevar int rl_ignore_completion_duplicates
+If non-zero, then disallow duplicates in the matches.  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 on entry, and can only be changed
+within a completion entry generator function.  If it is set to a non-zero
+value, directory names have a slash appended and Readline attempts to
+quote completed filenames if they contain any embedded word break
+characters.
+@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
+on entry, and can only be changed within a completion entry generator
+function.  The quoting is effected via a call to the function pointed to
+by @code{rl_filename_quoting_function}.
+@end deftypevar
+
+@deftypevar int rl_inhibit_completion
+If this variable is non-zero, completion is inhibit<ed.  The completion
+character will be inserted as any other bound to @code{self-insert}.
+@end deftypevar
+
+@deftypevar {Function *} 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 {Function *} 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.  It could be used
+to expand symbolic links or shell variables in pathnames.

+@node Introduction and Notation
+@section Introduction to Line Editing
+
+The following paragraphs describe the notation used to represent
+keystrokes.
+
+The text @key{C-k} is read as `Control-K' and describes the character
+produced when the @key{k} key is pressed while the Control key
+is depressed.
+
+The text @key{M-k} is read as `Meta-K' and describes the character
+produced when the meta key (if you have one) is depressed, and the @key{k}
+key is pressed.  If you do not have a meta key, the identical keystroke
+can be generated by typing @key{ESC} @i{first}, and then typing @key{k}.
+Either process is known as @dfn{metafying} the @key{k} key.
+
+The text @key{M-C-k} is read as `Meta-Control-k' and describes the
+character produced by @dfn{metafying} @key{C-k}.
+
+In addition, several keys have their own names.  Specifically,
+@key{DEL}, @key{ESC}, @key{LFD}, @key{SPC}, @key{RET}, and @key{TAB} all
+stand for themselves when seen in this text, or in an init file
+(@pxref{Readline Init File}).
+
+@node Readline Interaction
+@section Readline Interaction
+@cindex interaction, readline
+
+Often during an interactive session you type in a long line of text,
+only to notice that the first word on the line is misspelled.  The
+Readline library gives you a set of commands for manipulating the text
+as you type it in, allowing you to just fix your typo, and not forcing
+you to retype the majority of the line.  Using these editing commands,
+you move the cursor to the place that needs correction, and delete or
+insert the text of the corrections.  Then, when you are satisfied with
+the line, you simply press @key{RETURN}.  You do not have to be at the
+end of the line to press @key{RETURN}; the entire line is accepted
+regardless of the location of the cursor within the line.

+
+@node Readline Bare Essentials
+@subsection Readline Bare Essentials
+@cindex notation, readline
+@cindex command editing
+@cindex editing command lines
+
+In order to enter characters into the line, simply type them.  The typed
+character appears where the cursor was, and then the cursor moves one
+space to the right.  If you mistype a character, you can use your
+erase character to back up and delete the mistyped character.
+
+Sometimes you may miss typing a character that you wanted to type, and
+not notice your error until you have typed several other characters.  In
+that case, you can type @key{C-b} to move the cursor to the left, and then
+correct your mistake.  Afterwards, you can move the cursor to the right
+with @key{C-f}.
+
+When you add text in the middle of a line, you will notice that characters
+to the right of the cursor are `pushed over' to make room for the text
+that you have inserted.  Likewise, when you delete text behind the cursor,
+characters to the right of the cursor are `pulled back' to fill in the
+blank space created by the removal of the text.  A list of the basic bare
+essentials for editing the text of an input line follows.
+
+@table @asis
+@item @key{C-b}
+Move back one character.
+@item @key{C-f}
+Move forward one character.
+@item @key{DEL}
+Delete the character to the left of the cursor.
+@item @key{C-d}
+Delete the character underneath the cursor.
+@item @w{Printing characters}
+Insert the character into the line at the cursor.
+@item @key{C-_}
+Undo the last editing command.  You can undo all the way back to an
+empty line.
+@end table
+
+@node Readline Movement Commands
+@subsection Readline Movement Commands
+
+
+The above table describes the most basic possible keystrokes that you need
+in order to do editing of the input line.  For your convenience, many
+other commands have been added in addition to @key{C-b}, @key{C-f},
+@key{C-d}, and @key{DEL}.  Here are some commands for moving more rapidly
+about the line.
+
+@table @key
+@item C-a
+Move to the start of the line.
+@item C-e
+Move to the end of the line.
+@item M-f
+Move forward a word, where a word is composed of letters and digits.
+@item M-b
+Move backward a word.
+@item C-l
+Clear the screen, reprinting the current line at the top.
+@end table
+
+Notice how @key{C-f} moves forward a character, while @key{M-f} moves
+forward a word.  It is a loose convention that control keystrokes
+operate on characters while meta keystrokes operate on words.
+
+@node Readline Killing Commands
+@subsection Readline Killing Commands
+
+@cindex killing text
+@cindex yanking text
+
+@dfn{Killing} text means to delete the text from the line, but to save
+it away for later use, usually by @dfn{yanking} (re-inserting)
+it back into the line.
+If the description for a command says that it `kills' text, then you can
+be sure that you can get the text back in a different (or the same)
+place later.
+
+When you use a kill command, the text is saved in a @dfn{kill-ring}.
+Any number of consecutive kills save all of the killed text together, so
+that when you yank it back, you get it all.  The kill
+ring is not line specific; the text that you killed on a previously
+typed line is available to be yanked back later, when you are typing
+another line.
+@cindex kill ring
+
+Here is the list of commands for killing text.
+
+@table @key
+@item C-k
+Kill the text from the current cursor position to the end of the line.
+
+@item M-d
+Kill from the cursor to the end of the current word, or if between
+words, to the end of the next word.
+
+@item M-DEL
+Kill from the cursor the start of the previous word, or if between
+words, to the start of the previous word.
+
+@item C-w
+Kill from the cursor to the previous whitespace.  This is different than
+@key{M-DEL} because the word boundaries differ.
+
+@end table
+
+Here is how to @dfn{yank} the text back into the line.  Yanking
+means to copy the most-recently-killed text from the kill buffer.
+
+@table @key
+@item C-y
+Yank the most recently killed text back into the buffer at the cursor.
+
+@item M-y
+Rotate the kill-ring, and yank the new top.  You can only do this if
+the prior command is @key{C-y} or @key{M-y}.
+@end table
+
+@node Readline Arguments
+@subsection Readline Arguments
+
+You can pass numeric arguments to Readline commands.  Sometimes the
+argument acts as a repeat count, other times it is the @i{sign} of the
+argument that is significant.  If you pass a negative argument to a
+command which normally acts in a forward direction, that command will
+act in a backward direction.  For example, to kill text back to the
+start of the line, you might type @samp{M-- C-k}.
+
+The general way to pass numeric arguments to a command is to type meta
+digits before the command.  If the first `digit' typed is a minus
+sign (@key{-}), then the sign of the argument will be negative.  Once
+you have typed one meta digit to get the argument started, you can type
+the remainder of the digits, and then the command.  For example, to give
+the @key{C-d} command an argument of 10, you could type @samp{M-1 0 C-d}.
+
+@node Searching
+@subsection Searching for Commands in the History
+
+Readline provides commands for searching through the command history
+@ifset BashFeatures
+(@pxref{Bash History Facilities})
+@end ifset
+for lines containing a specified string.
+There are two search modes:  @var{incremental} and @var{non-incremental}.
+
+Incremental searches begin before the user has finished typing the
+search string.
+As each character of the search string is typed, Readline displays
+the next entry from the history matching the string typed so far.
+An incremental search requires only as many characters as needed to
+find the desired history entry.
+The @key{ESC} character is used to terminate an incremental search.
+@key{C-j} will also terminate the search.
+@key{C-g} will abort an incremental search and restore the original line.
+When the search is terminated, the history entry containing the
+search string becomes the current line.
+To find other matching entries in the history list, type @key{C-s} or
+@key{C-r} as appropriate.
+This will search backward or forward in the history for the next
+entry matching the search string typed so far.
+Any other key sequence bound to a Readline command will terminate
+the search and execute that command.
+For instance, a @key{RET} will terminate the search and accept
+the line, thereby executing the command from the history list.
+
+Non-incremental searches read the entire search string before starting
+to search for matching history lines.  The search string may be
+typed by the user or be part of the contents of the current line.
+
+@node Readline Init File
+@section Readline Init File
+@cindex initialization file, readline
+
+Although the Readline library comes with a set of @code{emacs}-like
+keybindings installed by default, it is possible to use a different set
+of keybindings.
+Any user can customize programs that use Readline by putting
+commands in an @dfn{inputrc} file in his home directory.
+The name of this
+@ifset BashFeatures
+file is taken from the value of the shell variable @code{INPUTRC}.  If
+@end ifset
+@ifclear BashFeatures
+file is taken from the value of the environment variable @code{INPUTRC}.  If
+@end ifclear
+that variable is unset, the default is @file{~/.inputrc}.
+
+When a program which uses the Readline library starts up, the
+init file is read, and the key bindings are set.
+
+In addition, the @code{C-x C-r} command re-reads this init file, thus
+incorporating any changes that you might have made to it.
+
+@menu
+* Readline Init File Syntax::	Syntax for the commands in the inputrc file.
+
+* Conditional Init Constructs::	Conditional key bindings in the inputrc file.
+
+* Sample Init File::		An example inputrc file.
+@end menu
+
+@node Readline Init File Syntax
+@subsection Readline Init File Syntax
+
+There are only a few basic constructs allowed in the
+Readline init file.  Blank lines are ignored.
+Lines beginning with a @samp{#} are comments.
+Lines beginning with a @samp{$} indicate conditional
+constructs (@pxref{Conditional Init Constructs}).  Other lines
+denote variable settings and key bindings.
+
+@table @asis
+@item Variable Settings
+You can modify the run-time behavior of Readline by
+altering the values of variables in Readline
+using the @code{set} command within the init file.  Here is how to
+change from the default Emacs-like key binding to use
+@code{vi} line editing commands:
+
+@example
+set editing-mode vi
+@end example
+
+A great deal of run-time behavior is changeable with the following
+variables.
+
+@table @code
+
+@item bell-style
+@vindex bell-style
+Controls what happens when Readline wants to ring the terminal bell.
+If set to @samp{none}, Readline never rings the bell.  If set to
+@samp{visible}, Readline uses a visible bell if one is available.
+If set to @samp{audible} (the default), Readline attempts to ring
+the terminal's bell.
+
+@item comment-begin
+@vindex comment-begin
+The string to insert at the beginning of the line when the
+@code{insert-comment} command is executed.  The default value
+is @code{"#"}.
+
+@item completion-ignore-case
+If set to @samp{on}, Readline performs filename matching and completion
+in a case-insensitive fashion.
+The default value is @samp{off}.
+
+@item completion-query-items
+@vindex completion-query-items
+The number of possible completions that determines when the user is
+asked whether he wants to see the list of possibilities.  If the
+number of possible completions is greater than this value,
+Readline will ask the user whether or not he wishes to view
+them; otherwise, they are simply listed.  The default limit is
+@code{100}.
+
+@item convert-meta
+@vindex convert-meta
+If set to @samp{on}, Readline will convert characters with the
+eighth bit set to an ASCII key sequence by stripping the eighth
+bit and prepending an @key{ESC} character, converting them to a
+meta-prefixed key sequence.  The default value is @samp{on}.
+
+@item disable-completion
+@vindex disable-completion
+If set to @samp{On}, Readline will inhibit word completion.
+Completion  characters will be inserted into the line as if they had
+been mapped to @code{self-insert}.  The default is @samp{off}.
+
+@item editing-mode
+@vindex editing-mode
+The @code{editing-mode} variable controls which default set of
+key bindings is used.  By default, Readline starts up in Emacs editing
+mode, where the keystrokes are most similar to Emacs.  This variable can be
+set to either @samp{emacs} or @samp{vi}.
+
+@item enable-keypad
+@vindex enable-keypad
+When set to @samp{on}, Readline will try to enable the application
+keypad when it is called.  Some systems need this to enable the
+arrow keys.  The default is @samp{off}.
+
+@item expand-tilde
+@vindex expand-tilde
+If set to @samp{on}, tilde expansion is performed when Readline
+attempts word completion.  The default is @samp{off}.
+
+@item horizontal-scroll-mode
+@vindex horizontal-scroll-mode
+This variable can be set to either @samp{on} or @samp{off}.  Setting it
+to @samp{on} means that the text of the lines being edited will scroll
+horizontally on a single screen line when they are longer than the width
+of the screen, instead of wrapping onto a new screen line.  By default,
+this variable is set to @samp{off}.
+
+@item keymap
+@vindex keymap
+Sets Readline's idea of the current keymap for key binding commands.
+Acceptable @code{keymap} names are
+@code{emacs},
+@code{emacs-standard},
+@code{emacs-meta},
+@code{emacs-ctlx},
+@code{vi},
+@code{vi-command}, and
+@code{vi-insert}.
+@code{vi} is equivalent to @code{vi-command}; @code{emacs} is
+equivalent to @code{emacs-standard}.  The default value is @code{emacs}.
+The value of the @code{editing-mode} variable also affects the
+default keymap.
+
+@item mark-directories
+If set to @samp{on}, completed directory names have a slash
+appended.  The default is @samp{on}.
+
+@item mark-modified-lines
+@vindex mark-modified-lines
+This variable, when set to @samp{on}, causes Readline to display an
+asterisk (@samp{*}) at the start of history lines which have been modified.
+This variable is @samp{off} by default.
+
+@item input-meta
+@vindex input-meta
+@vindex meta-flag
+If set to @samp{on}, Readline will enable eight-bit input (it
+will not strip the eighth bit from the characters it reads),
+regardless of what the terminal claims it can support.  The
+default value is @samp{off}.  The name @code{meta-flag} is a
+synonym for this variable.
+
+@item output-meta
+@vindex output-meta
+If set to @samp{on}, Readline will display characters with the
+eighth bit set directly rather than as a meta-prefixed escape
+sequence.  The default is @samp{off}.
+
+@item print-completions-horizontally
+If set to @samp{on}, Readline will display completions with matches
+sorted horizontally in alphabetical order, rather than down the screen.
+The default is @samp{off}.
+
+@item show-all-if-ambiguous
+@vindex show-all-if-ambiguous
+This alters the default behavior of the completion functions.  If
+set to @samp{on}, 
+words which have more than one possible completion cause the
+matches to be listed immediately instead of ringing the bell.
+The default value is @samp{off}.
+
+@item visible-stats
+@vindex visible-stats
+If set to @samp{on}, a character denoting a file's type
+is appended to the filename when listing possible
+completions.  The default is @samp{off}.
+
+@end table
+
+@item Key Bindings
+The syntax for controlling key bindings in the init file is
+simple.  First you have to know the name of the command that you
+want to change.  The following sections contain tables of the command
+name, the default keybinding, if any, and a short description of what
+the command does.
+
+Once you know the name of the command, simply place the name of the key
+you wish to bind the command to, a colon, and then the name of the
+command on a line in the init file.  The name of the key
+can be expressed in different ways, depending on which is most
+comfortable for you.
+
+@table @asis
+@item @w{@var{keyname}: @var{function-name} or @var{macro}}
+@var{keyname} is the name of a key spelled out in English.  For example:
+@example
+Control-u: universal-argument
+Meta-Rubout: backward-kill-word
+Control-o: "> output"
+@end example
+
+In the above example, @key{C-u} is bound to the function
+@code{universal-argument}, and @key{C-o} is bound to run the macro
+expressed on the right hand side (that is, to insert the text
+@samp{> output} into the line).
+
+@item @w{"@var{keyseq}": @var{function-name} or @var{macro}}
+@var{keyseq} differs from @var{keyname} above in that strings
+denoting an entire key sequence can be specified, by placing
+the key sequence in double quotes.  Some GNU Emacs style key
+escapes can be used, as in the following example, but the
+special character names are not recognized.
+
+@example
+"\C-u": universal-argument
+"\C-x\C-r": re-read-init-file
+"\e[11~": "Function Key 1"
+@end example
+
+In the above example, @key{C-u} is bound to the function
+@code{universal-argument} (just as it was in the first example),
+@samp{@key{C-x} @key{C-r}} is bound to the function @code{re-read-init-file},
+and @samp{@key{ESC} @key{[} @key{1} @key{1} @key{~}} is bound to insert
+the text @samp{Function Key 1}.
+
+@end table
+
+The following GNU Emacs style escape sequences are available when
+specifying key sequences:
+
+@table @code
+@item @kbd{\C-}
+control prefix
+@item @kbd{\M-}
+meta prefix
+@item @kbd{\e}
+an escape character
+@item @kbd{\\}
+backslash
+@item @kbd{\"}
+@key{"}
+@item @kbd{\'}
+@key{'}
+@end table
+
+In addition to the GNU Emacs style escape sequences, a second
+set of backslash escapes is available:
+
+@table @code
+@item \a
+alert (bell)
+@item \b
+backspace
+@item \d
+delete
+@item \f
+form feed
+@item \n
+newline
+@item \r
+carriage return
+@item \t
+horizontal tab
+@item \v
+vertical tab
+@item \@var{nnn}
+the character whose ASCII code is the octal value @var{nnn}
+(one to three digits)
+@item \x@var{nnn}
+the character whose ASCII code is the hexadecimal value @var{nnn}
+(one to three digits)
+@end table
+
+When entering the text of a macro, single or double quotes must
+be used to indicate a macro definition.
+Unquoted text is assumed to be a function name.
+In the macro body, the backslash escapes described above are expanded.
+Backslash will quote any other character in the macro text,
+including @samp{"} and @samp{'}.
+For example, the following binding will make @samp{C-x \}
+insert a single @samp{\} into the line:
+@example
+"\C-x\\": "\\"
+@end example
+
+@end table
+
+@node Conditional Init Constructs
+@subsection Conditional Init Constructs
+
+Readline implements a facility similar in spirit to the conditional
+compilation features of the C preprocessor which allows key
+bindings and variable settings to be performed as the result
+of tests.  There are four parser directives used.
+
+@table @code
+@item $if
+The @code{$if} construct allows bindings to be made based on the
+editing mode, the terminal being used, or the application using
+Readline.  The text of the test extends to the end of the line;
+no characters are required to isolate it.
+
+@table @code
+@item mode
+The @code{mode=} form of the @code{$if} directive is used to test
+whether Readline is in @code{emacs} or @code{vi} mode.
+This may be used in conjunction
+with the @samp{set keymap} command, for instance, to set bindings in
+the @code{emacs-standard} and @code{emacs-ctlx} keymaps only if
+Readline is starting out in @code{emacs} mode.
+
+@item term
+The @code{term=} form may be used to include terminal-specific
+key bindings, perhaps to bind the key sequences output by the
+terminal's function keys.  The word on the right side of the
+@samp{=} is tested against both the full name of the terminal and
+the portion of the terminal name before the first @samp{-}.  This
+allows @code{sun} to match both @code{sun} and @code{sun-cmd},
+for instance.
+
+@item application
+The @var{application} construct is used to include
+application-specific settings.  Each program using the Readline
+library sets the @var{application name}, and you can test for it. 
+This could be used to bind key sequences to functions useful for
+a specific program.  For instance, the following command adds a
+key sequence that quotes the current or previous word in Bash:
+@example
+$if Bash
+# Quote the current or previous word
+"\C-xq": "\eb\"\ef\""
+$endif
+@end example
+@end table
+
+@item $endif
+This command, as seen in the previous example, terminates an
+@code{$if} command.
+
+@item $else
+Commands in this branch of the @code{$if} directive are executed if
+the test fails.
+
+@item $include
+This directive takes a single filename as an argument and reads commands
+and bindings from that file.
+@example
+$include /etc/inputrc
+@end example
+@end table
+
+@node Sample Init File
+@subsection Sample Init File

+@subsection Killing And Yanking
+
+@ftable @code
+
+@item kill-line (C-k)
+Kill the text from the current cursor position to the end of the line.
+
+@item backward-kill-line (C-x Rubout)
+Kill backward to the beginning of the line.
+
+@item unix-line-discard (C-u)
+Kill backward from the cursor to the beginning of the current line.
+The killed text is saved on the kill-ring.
+
+@item kill-whole-line ()
+Kill all characters on the current line, no matter where the
+cursor is.  By default, this is unbound.
+
+@item kill-word (M-d)
+Kill from the cursor to the end of the current word, or if between
+words, to the end of the next word.  Word boundaries are the same
+as @code{forward-word}.
+
+@item backward-kill-word (M-DEL)
+Kill the word behind the cursor.  Word boundaries are the same
+as @code{backward-word}.
+
+@item unix-word-rubout (C-w)
+Kill the word behind the cursor, using white space as a word
+boundary.  The killed text is saved on the kill-ring.
+
+@item delete-horizontal-space ()
+Delete all spaces and tabs around point.  By default, this is unbound.
+
+@item kill-region ()
+Kill the text between the point and the @emph{mark} (saved
+cursor position).  This text is referred to as the @var{region}.
+By default, this command is unbound.
+
+@item copy-region-as-kill ()
+Copy the text in the region to the kill buffer, so it can be yanked
+right away.  By default, this command is unbound.
+
+@item copy-backward-word ()
+Copy the word before point to the kill buffer.
+The word boundaries are the same as @code{backward-word}.
+By default, this command is unbound.
+
+@item copy-forward-word ()
+Copy the word following point to the kill buffer.
+The word boundaries are the same as @code{forward-word}.
+By default, this command is unbound.
+
+@item yank (C-y)
+Yank the top of the kill ring into the buffer at the current
+cursor position.
+
+@item yank-pop (M-y)
+Rotate the kill-ring, and yank the new top.  You can only do this if
+the prior command is yank or yank-pop.
+@end ftable
+
+@node Numeric Arguments
+@subsection Specifying Numeric Arguments
+@ftable @code
+
+@item digit-argument (M-0, M-1, ... M--)
+Add this digit to the argument already accumulating, or start a new
+argument.  @key{M--} starts a negative argument.
+
+@item universal-argument ()
+This is another way to specify an argument.
+If this command is followed by one or more digits, optionally with a
+leading minus sign, those digits define the argument.
+If the command is followed by digits, executing @code{universal-argument}
+again ends the numeric argument, but is otherwise ignored.
+As a special case, if this command is immediately followed by a
+character that is neither a digit or minus sign, the argument count
+for the next command is multiplied by four.
+The argument count is initially one, so executing this function the
+first time makes the argument count four, a second time makes the
+argument count sixteen, and so on.
+By default, this is not bound to a key.
+@end ftable
+
+@node Commands For Completion
+@subsection Letting Readline Type For You
+
+@ftable @code
+@item complete (TAB)
+Attempt to do completion on the text before the cursor.  This is
+application-specific.  Generally, if you are typing a filename
+argument, you can do filename completion; if you are typing a command,
+you can do command completion; if you are typing in a symbol to GDB, you
+can do symbol name completion; if you are typing in a variable to Bash,
+you can do variable name completion, and so on.
+@ifset BashFeatures
+Bash attempts completion treating the text as a variable (if the
+text begins with @samp{$}), username (if the text begins with
+@samp{~}), hostname (if the text begins with @samp{@@}), or
+command (including aliases and functions) in turn.  If none 
+of these produces a match, filename completion is attempted.
+@end ifset
+
+@item possible-completions (M-?)
+List the possible completions of the text before the cursor.
+
+@item insert-completions (M-*)
+Insert all completions of the text before point that would have
+been generated by @code{possible-completions}.
+
+@item menu-complete ()
+Similar to @code{complete}, but replaces the word to be completed
+with a single match from the list of possible completions.
+Repeated execution of @code{menu-complete} steps through the list
+of possible completions, inserting each match in turn.
+At the end of the list of completions, the bell is rung and the
+original text is restored.
+An argument of @var{n} moves @var{n} positions forward in the list
+of matches; a negative argument may be used to move backward
+through the list.
+This command is intended to be bound to @code{TAB}, but is unbound
+by default.
+
+@ifset BashFeatures
+@item complete-filename (M-/)
+Attempt filename completion on the text before point.
+
+@item possible-filename-completions (C-x /)
+List the possible completions of the text before point,
+treating it as a filename.
+
+@item complete-username (M-~)
+Attempt completion on the text before point, treating
+it as a username.
+
+@item possible-username-completions (C-x ~)
+List the possible completions of the text before point,
+treating it as a username.
+
+@item complete-variable (M-$)
+Attempt completion on the text before point, treating
+it as a shell variable.
+
+@item possible-variable-completions (C-x $)
+List the possible completions of the text before point,
+treating it as a shell variable.
+
+@item complete-hostname (M-@@)
+Attempt completion on the text before point, treating
+it as a hostname.
+
+@item possible-hostname-completions (C-x @@)
+List the possible completions of the text before point,
+treating it as a hostname.
+
+@item complete-command (M-!)
+Attempt completion on the text before point, treating
+it as a command name.  Command completion attempts to
+match the text against aliases, reserved words, shell
+functions, shell builtins, and finally executable filenames,
+in that order.
+
+@item possible-command-completions (C-x !)
+List the possible completions of the text before point,
+treating it as a command name.
+
+@item dynamic-complete-history (M-TAB)
+Attempt completion on the text before point, comparing
+the text against lines from the history list for possible
+completion matches.
+
+@item complete-into-braces (M-@{)
+Perform filename completion and return the list of possible completions
+enclosed within braces so the list is available to the shell
+(@pxref{Brace Expansion}).
+
+@end ifset
+@end ftable
+
+@node Keyboard Macros
+@subsection Keyboard Macros
+@ftable @code
+
+@item start-kbd-macro (C-x ()
+Begin saving the characters typed into the current keyboard macro.
+
+@item end-kbd-macro (C-x ))
+Stop saving the characters typed into the current keyboard macro
+and save the definition.
+
+@item call-last-kbd-macro (C-x e)
+Re-execute the last keyboard macro defined, by making the characters
+in the macro appear as if typed at the keyboard.
+
+@end ftable
+
+@node Miscellaneous Commands
+@subsection Some Miscellaneous Commands
+@ftable @code
+
+@item re-read-init-file (C-x C-r)
+Read in the contents of the inputrc file, and incorporate
+any bindings or variable assignments found there.
+
+@item abort (C-g)
+Abort the current editing command and
+ring the terminal's bell (subject to the setting of
+@code{bell-style}).
+
+@item do-uppercase-version (M-a, M-b, M-@var{x}, @dots{})
+If the metafied character @var{x} is lowercase, run the command
+that is bound to the corresponding uppercase character.
+
+@item prefix-meta (ESC)
+Make the next character typed be metafied.  This is for keyboards
+without a meta key.  Typing @samp{ESC f} is equivalent to typing
+@samp{M-f}.
+
+@item undo (C-_, C-x C-u)
+Incremental undo, separately remembered for each line.
+
+@item revert-line (M-r)
+Undo all changes made to this line.  This is like executing the @code{undo}
+command enough times to get back to the beginning.
+
+@item tilde-expand (M-~)
+Perform tilde expansion on the current word.
+
+@item set-mark (C-@@)
+Set the mark to the current point.  If a
+numeric argument is supplied, the mark is set to that position.
+
+@item exchange-point-and-mark (C-x C-x)
+Swap the point with the mark.  The current cursor position is set to
+the saved position, and the old cursor position is saved as the mark.
+
+@item character-search (C-])
+A character is read and point is moved to the next occurrence of that
+character.  A negative count searches for previous occurrences.
+
+@item character-search-backward (M-C-])
+A character is read and point is moved to the previous occurrence
+of that character.  A negative count searches for subsequent
+occurrences.
+
+@item insert-comment (M-#)
+The value of the @code{comment-begin}
+variable is inserted at the beginning of the current line,
+and the line is accepted as if a newline had been typed.
+@ifset BashFeatures
+This makes the current line a shell comment.
+@end ifset
+
+@item dump-functions ()
+Print all of the functions and their key bindings to the
+Readline output stream.  If a numeric argument is supplied,
+the output is formatted in such a way that it can be made part
+of an @var{inputrc} file.  This command is unbound by default.
+
+@item dump-variables ()
+Print all of the settable variables and their values to the
+Readline output stream.  If a numeric argument is supplied,
+the output is formatted in such a way that it can be made part
+of an @var{inputrc} file.  This command is unbound by default.
+
+@item dump-macros ()
+Print all of the Readline key sequences bound to macros and the
+strings they ouput.  If a numeric argument is supplied,
+the output is formatted in such a way that it can be made part
+of an @var{inputrc} file.  This command is unbound by default.
+
+@ifset BashFeatures
+@item glob-expand-word (C-x *)
+The word before point is treated as a pattern for pathname expansion,
+and the list of matching file names is inserted, replacing the word.
+
+@item glob-list-expansions (C-x g)
+The list of expansions that would have been generated by
+@code{glob-expand-word} is displayed, and the line is redrawn.
+
+@item display-shell-version (C-x C-v)
+Display version information about the current instance of Bash.
+
+@item shell-expand-line (M-C-e)
+Expand the line as the shell does.
+This performs alias and history expansion as well as all of the shell
+word expansions (@pxref{Shell Expansions}).
+
+@item history-expand-line (M-^)
+Perform history expansion on the current line.
+
+@item magic-space ()
+Perform history expansion on the current line and insert a space
+(@pxref{History Interaction}).
+
+@item alias-expand-line ()
+Perform alias expansion on the current line (@pxref{Aliases}).
+
+@item history-and-alias-expand-line ()
+Perform history and alias expansion on the current line.
+
+@item insert-last-argument (M-., M-_)
+A synonym for @code{yank-last-arg}.
+
+@item operate-and-get-next (C-o)
+Accept the current line for execution and fetch the next line
+relative to the current line from the history for editing.  Any
+argument is ignored.
+
+@item emacs-editing-mode (C-e)
+When in @code{vi} editing mode, this causes a switch back to
+@code{emacs} editing mode, as if the command @samp{set -o emacs} had
+been executed.
+
+@end ifset
+
+@end ftable
+
+@node Readline vi Mode
+@section Readline vi Mode
+
+While the Readline library does not have a full set of @code{vi}
+editing functions, it does contain enough to allow simple editing
+of the line.  The Readline @code{vi} mode behaves as specified in
+the @sc{POSIX} 1003.2 standard.
+
+@ifset BashFeatures
+In order to switch interactively between @code{emacs} and @code{vi}
+editing modes, use the @samp{set -o emacs} and @samp{set -o vi}
+commands (@pxref{The Set Builtin}).
+@end ifset
+@ifclear BashFeatures
+In order to switch interactively between @code{emacs} and @code{vi}
+editing modes, use the command M-C-j (toggle-editing-mode).
+@end ifclear
+The Readline default is @code{emacs} mode.
+
+When you enter a line in @code{vi} mode, you are already placed in
+`insertion' mode, as if you had typed an @samp{i}.  Pressing @key{ESC}
+switches you into `command' mode, where you can edit the text of the
+line with the standard @code{vi} movement keys, move to previous
+history lines with @samp{k} and subsequent lines with @samp{j}, and
+so forth.

+# In the interest of general portability, some common bourne shell
+# constructs were avoided because they weren't guaranteed to be available
+# in some earlier implementations.  I've tried to make this program as
+# portable as possible.  Welcome to unix, where the lowest common
+# denominator is rapidly diminishing.
+#
+# Among the more interesting lossages I noticed with some bourne shells
+# are:
+#     * No shell functions.
+#     * No `unset' builtin.
+#     * `shift' cannot take a numeric argument, and signals an error if
+#       there are no arguments to shift.

+.TH TEXI2HTML 1 "09/10/96"
+.AT 3
+.SH NAME
+texi2html \- a Texinfo to HTML converter
+.SH SYNOPSIS
+.B texi2html [options] file
+.PP
+.B texi2html -check [-verbose] files
+.SH DESCRIPTION
+.I Texi2html
+converts the given Texinfo file to a set of HTML files. It tries to handle
+most of the Texinfo commands. It creates hypertext links for cross-references,
+footnotes...
+.PP
+It also tries to add links from a reference to its corresponding entry in the
+bibliography (if any). It may also handle a glossary (see the
+.B \-glossary
+option).
+.PP
+.I Texi2html
+creates several files depending on the contents of the Texinfo file and on
+the chosen options (see FILES).
+.PP
+The HTML files created by
+.I texi2html
+are closer to TeX than to Info, that's why
+.I texi2html
+converts @iftex sections and not @ifinfo ones by default. You can reverse
+this with the \-expandinfo option.
+.SH OPTIONS
+.TP 12
+.B \-check
+Check the given file and give the list of all things that may be Texinfo commands.
+This may be used to check the output of
+.I texi2html
+to find the Texinfo commands that have been left in the HTML file.
+.TP
+.B \-expandinfo
+Expand @ifinfo sections, not @iftex ones.
+.TP
+.B \-glossary
+Use the section named 'Glossary' to build a list of terms and put links in the HTML
+document from each term toward its definition.
+.TP
+.B \-invisible \fIname\fP
+Use \fIname\fP to create invisible destination anchors for index links. This is a workaround
+for a known bug of many WWW browsers, including xmosaic.
+.TP
+.B \-I \fIdir\fP
+Look also in \fIdir\fP to find included files.
+.TP
+.B \-menu
+Show the Texinfo menus; by default they are ignored.
+.TP
+.B \-monolithic
+Output only one file, including the table of contents and footnotes.
+.TP
+.B \-number
+Number the sections.
+.TP
+.B \-split_chapter
+Split the output into several HTML files (one per main section:
+chapter, appendix...).
+.TP
+.B \-split_node
+Split the output into several HTML files (one per node).
+.TP
+.B \-usage
+Print usage instructions, listing the current available command-line options.
+.TP
+.B \-verbose
+Give a verbose output. Can be used with the
+.B \-check
+option.
+.PP
+.SH FILES
+By default
+.I texi2html
+creates the following files (foo being the name of the Texinfo file):
+.TP 16
+.B foo_toc.html
+The table of contents.
+.TP
+.B foo.html
+The document's contents.
+.TP
+.B foo_foot.html
+The footnotes (if any).
+.PP
+When used with the
+.B \-split
+option, it creates several files (one per chapter or node), named
+.B foo_n.html
+(n being the indice of the chapter or node), instead of the single
+.B foo.html
+file.
+.PP
+When used with the
+.B \-monolithic
+option, it creates only one file:
+.B foo.html
+.SH VARIABLES
+.I texi2html
+predefines the following variables: \fBhtml\fP, \fBtexi2html\fP.
+.SH ADDITIONAL COMMANDS
+.I texi2html
+implements the following non-Texinfo commands:
+.TP 16
+.B @ifhtml
+This indicates the start of an HTML section, this section will passed through
+without any modofication.
+.TP
+.B @end ifhtml
+This indcates the end of an HTML section.
+.SH VERSION
+This is \fItexi2html\fP version 1.51, 09/10/96.
+.PP
+The latest version of \fItexi2html\fP can be found in WWW, cf. URL
+http://wwwcn.cern.ch/dci/texi2html/
