| sect(Description)
 | |
| pindex(ZLE, use of)
 | |
| If the tt(ZLE) option is set (which it is by default in interactive shells)
 | |
| and the shell input is attached to the terminal, the user
 | |
| is able to edit command lines.
 | |
| 
 | |
| There are two display modes.  The first, multiline mode, is the
 | |
| default.  It only works if the tt(TERM) parameter is set to a valid
 | |
| terminal type that can move the cursor up.  The second, single line
 | |
| mode, is used if tt(TERM) is invalid or incapable of moving the
 | |
| cursor up, or if the tt(SINGLE_LINE_ZLE) option is set.
 | |
| pindex(SINGLE_LINE_ZLE, use of)
 | |
| cindex(ksh, editor mode)
 | |
| cindex(editor ksh style)
 | |
| This mode
 | |
| is similar to bf(ksh), and uses no termcap sequences.  If tt(TERM) is
 | |
| "emacs", the tt(ZLE) option will be unset by default.
 | |
| sect(Keymaps)
 | |
| cindex(keymaps)
 | |
| cindex(key bindings)
 | |
| cindex(bindings, key)
 | |
| A keymap in ZLE contains a set of bindings between key sequences
 | |
| and ZLE commands.  The empty key sequence cannot be bound.
 | |
| 
 | |
| There can be any number of keymaps at any time, and each keymap has one
 | |
| or more names.  If all of a keymap's names are deleted, it disappears.
 | |
| findex(bindkey, use of)
 | |
| tt(bindkey) can be used to manipulate keymap names.
 | |
| 
 | |
| Initially, there are four keymaps:
 | |
| 
 | |
| startsitem()
 | |
| sitem(tt(emacs))(EMACS emulation)
 | |
| sitem(tt(viins))(vi emulation - insert mode)
 | |
| sitem(tt(vicmd))(vi emulation - command mode)
 | |
| sitem(tt(.safe))(fallback keymap)
 | |
| endsitem()
 | |
| 
 | |
| The `tt(.safe)' keymap is special.  It can never be altered, and the name
 | |
| can never be removed.  However, it can be linked to other names, which can
 | |
| be removed.  In the future other special keymaps may be added; users should
 | |
| avoid using names beginning with `tt(.)' for their own keymaps.
 | |
| 
 | |
| vindex(VISUAL)
 | |
| vindex(EDITOR)
 | |
| In addition to these four names, either `tt(emacs)' or `tt(viins)' is
 | |
| also linked to the name `tt(main)'.  If one of the tt(VISUAL) or
 | |
| tt(EDITOR) environment variables contain the string `tt(vi)' when the shell
 | |
| starts up then it will be `tt(viins)', otherwise it will be `tt(emacs)'.
 | |
| tt(bindkey)'s tt(-e) and tt(-v)
 | |
| options provide a convenient way to override this default choice.
 | |
| 
 | |
| When the editor starts up, it will select the `tt(main)' keymap.
 | |
| If that keymap doesn't exist, it will use `tt(.safe)' instead.
 | |
| 
 | |
| In the `tt(.safe)' keymap, each single key is bound to tt(self-insert),
 | |
| except for ^J (line feed) and ^M (return) which are bound to tt(accept-line).
 | |
| This is deliberately not pleasant to use; if you are using it, it
 | |
| means you deleted the main keymap, and you should put it back.
 | |
| subsect(Reading Commands)
 | |
| When ZLE is reading a command from the terminal, it may read a sequence
 | |
| that is bound to some command and is also a prefix of a longer bound string.
 | |
| In this case ZLE will wait a certain time to see if more characters
 | |
| are typed, and if not (or they don't match any longer string) it will
 | |
| execute the binding.  This timeout is defined by the tt(KEYTIMEOUT) parameter;
 | |
| its default is 0.4 sec.  There is no timeout if the prefix string is not
 | |
| itself bound to a command.
 | |
| 
 | |
| As well as ZLE commands, key sequences can be bound to other strings, by using
 | |
| `tt(bindkey -s)'.
 | |
| When such a sequence is read, the replacement string is pushed back as input,
 | |
| and the command reading process starts again using these fake keystrokes.
 | |
| This input can itself invoke further replacement strings, but in order to
 | |
| detect loops the process will be stopped if there are twenty such replacements
 | |
| without a real command being read.
 | |
| 
 | |
| sect(Zle Builtins)
 | |
| cindex(zle, builtin commands)
 | |
| The ZLE module contains three related builtin commands. The tt(bindkey)
 | |
| command manipulates keymaps and key bindings; the tt(vared) command invokes
 | |
| ZLE on the value of a shell parameter; and the tt(zle) command manipulates
 | |
| editing widgets and allows command line access to ZLE commands from within
 | |
| shell functions.

| item(tt(bindkey) [ var(options) ] [ var(in-string) ])(
 | |
| tt(bindkey)'s options can be divided into three categories: keymap selection,
 | |
| operation selection, and others.  The keymap selection options are:
 | |
| 
 | |
| startitem()
 | |
| item(tt(-e))(
 | |
| Selects keymap `tt(emacs)', and also links it to `tt(main)'.
 | |
| )
 | |
| item(tt(-v))(
 | |
| Selects keymap `tt(viins)', and also links it to `tt(main)'.
 | |
| )
 | |
| item(tt(-a))(
 | |
| Selects keymap `tt(vicmd)'.
 | |
| )
 | |
| item(tt(-M))(
 | |
| The first non-option argument is used as a keymap name,
 | |
| and does not otherwise count as an argument.
 | |
| )
 | |
| enditem()
 | |
| 
 | |
| If a keymap selection is required and none of the options above are used, the
 | |
| `tt(main)' keymap is used.  Some operations do not permit a keymap to be
 | |
| selected, namely:
 | |
| 
 | |
| startitem()
 | |
| item(tt(-l))(
 | |
| List all existing keymap names.  If the tt(-L)
 | |
| option is also used, list in the form of tt(bindkey)
 | |
| commands to create the keymaps.
 | |
| )
 | |
| item(tt(-d))(
 | |
| Delete all existing keymaps and reset to the default state.
 | |
| )
 | |
| item(tt(-D) var(keymap) ...)(
 | |
| Delete the named var(keymap)s.
 | |
| )
 | |
| item(tt(-A) var(old-keymap new-keymap))(
 | |
| Make the var(new-keymap) name an alias for var(old-keymap), so that
 | |
| both names refer to the same keymap.  The names have equal standing;
 | |
| if either is deleted, the other remains.  If there is already a keymap
 | |
| with the var(new-keymap) name, it is deleted.
 | |
| )
 | |
| item(tt(-N) var(new-keymap) [ var(old-keymap) ])(
 | |
| Create a new keymap, named var(new-keymap).  If a keymap already has that
 | |
| name, it is deleted.  If an var(old-keymap) name is given, the new keymap
 | |
| is initialized to be a duplicate of it, otherwise the new keymap will
 | |
| be empty.
 | |
| )
 | |
| enditem()
 | |
| 
 | |
| To use a newly created keymap, it should be linked to tt(main).  Hence
 | |
| the sequence of commands to create and use a new keymap `tt(mymap)'
 | |
| initialized from the tt(emacs) keymap (which remains unchanged) is:
 | |
| 
 | |
| example(bindkey -N mymap emacs
 | |
| bindkey -A mymap main)
 | |
| 
 | |
| Note that while `tt(bindkey -A) var(newmap) tt(main)' will work when
 | |
| var(newmap) is tt(emacs) or tt(viins), it will not work for tt(vicmd), as
 | |
| switching from vi insert to command mode becomes impossible.
 | |
| 
 | |
| The following operations act on the `tt(main)' keymap if no keymap
 | |
| selection option was given:
 | |
| 
 | |
| startitem()
 | |
| item(tt(-m))(
 | |
| Add the built-in set of meta-key bindings to the selected keymap.
 | |
| Only keys that are unbound or bound to tt(self-insert) are affected.
 | |
| )
 | |
| item(tt(-r) var(in-string) ...)(
 | |
| Unbind the specified var(in-string)s in the selected keymap.
 | |
| This is exactly equivalent to binding the strings to tt(undefined-key).
 | |
| When tt(-R) is also used, interpret the var(in-string)s as ranges.
 | |
| )
 | |
| item(tt(-s) var(in-string out-string) ...)(
 | |
| Bind each var(in-string) to each var(out-string).
 | |
| When var(in-string) is typed, var(out-string) will be
 | |
| pushed back and treated as input to the line editor.
 | |
| When tt(-R) is also used, interpret the var(in-string)s as ranges.
 | |
| )
 | |
| item(var(in-string command) ...)(
 | |
| Bind each var(in-string) to each var(command).
 | |
| When tt(-R) is used, interpret the var(in-string)s as ranges.
 | |
| )
 | |
| item([ var(in-string) ])(
 | |
| List key bindings.  If an var(in-string) is specified, the binding of
 | |
| that string in the selected keymap is displayed.  Otherwise, all key
 | |
| bindings in the selected keymap are displayed.  (As a special case,
 | |
| if the tt(-e) or tt(-v) option is used alone, the keymap is em(not)
 | |
| displayed - the implicit linking of keymaps is the only thing that
 | |
| happens.)
 | |
| 
 | |
| When the option tt(-p) is used, the var(in-string) must be present.
 | |
| The listing shows all bindings which have the given key sequence as a
 | |
| prefix, not including any bindings for the key sequence itself.
 | |
| 
 | |
| When the tt(-L) option is used, the list is in the form of tt(bindkey)
 | |
| commands to create the key bindings.
 | |
| )
 | |
| enditem()
 | |
| 
 | |
| When the tt(-R) option is used as noted above, a valid range consists of
 | |
| two characters, with an optional `tt(-)' between them.  All characters
 | |
| between the two specified, inclusive, are bound as specified.
 | |
| 
 | |
| For either var(in-string) or var(out-string), the following
 | |
| escape sequences are recognised:
 | |
| 
 | |
| startsitem()
 | |
| sitem(tt(\a))(bell character)
 | |
| sitem(tt(\b))(backspace)
 | |
| sitem(tt(\e), tt(\E))(escape)
 | |
| sitem(tt(\f))(form feed)
 | |
| sitem(tt(\n))(linefeed (newline))
 | |
| sitem(tt(\r))(carriage return)
 | |
| sitem(tt(\t))(horizontal tab)
 | |
| sitem(tt(\v))(vertical tab)
 | |
| sitem(tt(\)var(NNN))(character code in octal)

 | |
| sitem(tt(\C)[tt(-)]var(X))(control character)
 | |
| sitem(tt(^)var(X))(control character)
 | |
| endsitem()
 | |
| 
 | |
| In all other cases, `tt(\)' escapes the following character.  Delete is
 | |
| written as `tt(^?)'.  Note that `tt(\M^?)' and `tt(^\M?)' are not the same,
 | |
| and that (unlike emacs), the bindings `tt(\M-)var(X)' and `tt(\e)var(X)'
 | |
| are entirely distinct, although they are initialized to the same bindings
 | |
| by `tt(bindkey -m)'.

 | |
| buffer, and the line editor is invoked.  When the editor exits,
 | |
| var(name) is set to the string value returned by the editor.
 | |
| When the tt(-c) flag is given, the parameter is created if it doesn't
 | |
| already exist.  The tt(-a) flag may be given with tt(-c) to create
 | |
| an array parameter, or the tt(-A) flag to create an associative array.
 | |

| If an array or array slice is being edited, separator characters as defined
 | |
| in tt($IFS) will be shown quoted with a backslash, as will backslashes
 | |
| themselves.  Conversely, when the edited text is split into an array, a
 | |
| backslash quotes an immediately following separator character or backslash;
 | |
| no other special handling of backslashes, or any handling of quotes, is
 | |
| performed.

| active.  When a trap exits, the shell checks to see if the display needs

 | |
| widgets.  In general, the trap function may need to test whether zle is
 | |
| loaded before using this method; if it is not, there is no point in loading
 | |
| it specially since the line editor will not be active.
 | |
| 
 | |

| Invoke the specified widget.  This can only be done when ZLE is
 | |
| active; normally this will be within a user-defined widget.
 | |

 | |
| saved and then restored after the call to tt(widget); `tt(-n) var(num)'
 | |
| sets the numerical argument temporarily to var(num), while `tt(-N)' sets it
 | |
| to the default, i.e. as if there were none.
 | |
| 
 | |
| Any further arguments will be passed to the widget.  If it is a shell
 | |
| function, these are passed down as positional parameters; for builtin
 | |
| widgets it is up to the widget in question what it does with them.
 | |
| Currently arguments are only handled by the incremental-search commands,
 | |
| the tt(history-search-forward) and tt(-backward) and the corresponding
 | |
| functions prefixed by tt(vi-), and by tt(universal-argument).  No error is
 | |
| flagged if the command does not use the arguments, or only uses some of
 | |
| them.
 | |

| The return status reflects the success or failure of the operation carried
 | |
| out by the widget, or if it is a user-defined widget the return status of

| 
 | |
| A non-zero return status causes the shell to beep when the widget exits,

| unless the tt(BEEP) options was unset or the widget was called via the

 | |
| All actions in the editor are performed by `widgets'.  A widget's job is
 | |
| simply to perform some small action.  The ZLE commands that key sequences
 | |
| in keymaps are bound to are in fact widgets.  Widgets can be user-defined
 | |
| or built in.
 | |
| 
 | |
| The standard widgets built in to ZLE are listed in Standard Widgets below.
 | |
| Other built-in widgets can be defined by other modules (see
 | |
| ifzman(zmanref(zshmodules))\
 | |
| ifnzman(noderef(Zsh Modules))\
 | |
| ).  Each built-in widget has two names: its normal canonical name, and the
 | |
| same name preceded by a `tt(.)'.  The `tt(.)' name is special: it can't be
 | |
| rebound to a different widget.  This makes the widget available even when
 | |
| its usual name has been redefined.
 | |
| 
 | |
| User-defined widgets are defined using `tt(zle -N)', and implemented
 | |
| as shell functions.  When the widget is executed, the corresponding
 | |
| shell function is executed, and can perform editing (or other) actions.
 | |
| It is recommended that user-defined widgets should not have names
 | |
| starting with `tt(.)'.
 | |
| sect(User-Defined Widgets)
 | |
| cindex(widgets, user-defined)
 | |
| User-defined widgets, being implemented as shell functions,
 | |
| can execute any normal shell command.  They can also run other widgets
 | |
| (whether built-in or user-defined) using the tt(zle) builtin command.
 | |
| The standard input of the function is closed to prevent external commands
 | |
| from unintentionally blocking ZLE by reading from the terminal, but
 | |
| tt(read -k) or tt(read -q) can be used to read characters.  Finally,
 | |
| they can examine and edit the ZLE buffer being edited by
 | |
| reading and setting the special parameters described below.
 | |
| 
 | |
| cindex(parameters, editor)
 | |
| cindex(parameters, zle)
 | |
| These special parameters are always available in widget functions, but
 | |
| are not in any way special outside ZLE.  If they have some normal value
 | |
| outside ZLE, that value is temporarily inaccessible, but will return
 | |
| when the widget function exits.  These special parameters in fact have
 | |
| local scope, like parameters created in a function using tt(local).
 | |
| 
 | |
| Inside completion widgets and traps called while ZLE is active, these
 | |
| parameters are available read-only.

| startitem()
 | |
| vindex(BUFFER)
 | |
| item(tt(BUFFER) (scalar))(
 | |
| The entire contents of the edit buffer.  If it is written to, the

 | |
| item(tt(NUMERIC) (integer))(
 | |
| The numeric argument. If no numeric argument was given, this parameter
 | |
| is unset. When this is set inside a widget function, builtin widgets
 | |
| called with the tt(zle) builtin command will use the value
 | |
| assigned. If it is unset inside a widget function, builtin widgets
 | |
| called behave as if no numeric argument was given.
 | |
| )
 | |
| vindex(PENDING)
 | |
| item(tt(PENDING) (integer))(
 | |
| The number of bytes pending for input, i.e. the number of bytes which have

 | |
| is not able to get this information, this parameter will always have a
 | |
| value of zero.

 | |
| currently in.

| vi command mode and vi insert mode
 | |
| (the `tt(emacs)', `tt(vicmd)' and `tt(viins)' keymaps, respectively).
 | |
| 
 | |
| Note that cursor keys are bound to movement keys in all three keymaps;
 | |
| the shell assumes that the cursor keys send the key sequences reported
 | |
| by the terminal-handling library (termcap or terminfo).  The key sequences
 | |
| shown in the list are those based on the VT100, common on many modern
 | |
| terminals, but in fact these are not necessarily bound.  In the case of the
 | |
| tt(viins) keymap, the initial escape character of the sequences serves also
 | |
| to return to the tt(vicmd) keymap: whether this happens is determined by
 | |
| the tt(KEYTIMEOUT) parameter, see ifzman(zmanref(zshparam))\
