+=head1 NAME
+
+vim_mode.pl
+
+=head1 DESCRIPTION
+
+An Irssi script to emulate some of the vi(m) features for the Irssi inputline.
+
+=head1 INSTALLATION
+
+Copy into your F<~/.irssi/scripts/> directory and load with
+C</SCRIPT LOAD vim_mode.pl>. You may wish to have it autoload in one of the
+L<usual ways|https://github.com/shabble/irssi-docs/wiki/Guide#Autorunning_Scripts>.
+
+=head2 DEPENDENCIES
+
+For proper :ex mode support, vim-mode requires the installation of F<uberprompt.pl>
+Uberprompt can be downloaded from:
+
+L<https://github.com/shabble/irssi-scripts/raw/master/prompt_info/uberprompt.pl>
+
+and follow the instructions at the top of that file for installation.
+
+If you don't need Ex-mode, you can run vim_mode.pl without the
+uberprompt.pl script, but it is strongly recommended that you use it.
+
+=head3 Irssi requirements
+
+0.8.12 and above should work fine. However the following features are
+disabled in irssi < 0.8.13:
+
+=over 4
+
+=item * C<j> C<k> (only with count, they work fine without count in older versions)
+
+=item * C<gg>, C<G>
+
+=back
+
+It is intended to work with at Irssi 0.8.12 and later versions. However some
+features are disabled in older versions (see below for details).
+
+Perl >= 5.8.1 is recommended for UTF-8 support (which can be disabled if
+necessary). Please report bugs in older versions as well, we'll try to fix
+them. Later versions of Perl are also faster, which is probably beneficial
+to a script of this size and complexity.
+
+=head2 SETUP
+
+Vim Mode provides certain feedback to the user, such as the currently active
+mode (command, insert, ex), and if switching buffers, which buffer(s) currently
+match the search terms.
+
+There are two ways to go about displaying this information, as described in
+the following sections:
+
+=head3 Statusbar Items
+
+Run the following command to add a statusbar item that shows which mode
+you're in.
+
+C</statusbar window add vim_mode>
+
+And the following to let C<:b [str]> display a list of channels matching your
+search string.
+
+C</statusbar window add vim_windows>
+
+B<Note:> Remember to C</save> after adding these statusbar items to make them
+permanent.
+
+B<Note:> If you would rather have these statusbar items on your prompt
+line rather than thte window statusbar, please follow these steps.
+
+For technical reasons, I<uberprompt> must occasionally call C</statusbar prompt
+reset>, which will remove or deactivate any manually added items on the prompt
+statusbar. To get around this, uberprompt provides two command hooks,
+C<uberprompt_load_hook> and C<uberprompt_unload_hook>. Both of these settings
+can contain one (or more, using C</EVAL>) commands to be executed when the prompt
+is enabled and disabled, respectively.
+
+See the L<uberprompt documentation|https://github.com/shabble/irssi-scripts/blob/master/prompt_info/README.pod> for further details.
+
+For I<right-aligned> items (that is, after the input field:
+
+=over 4
+
+=item 1 C</alias vm_add /^statusbar prompt add -after input -alignment right vim_mode>
+
+=item 2 C</alias vm_del /^statusbar prompt remove vim_mode>
+
+=item 3 C</set uberprompt_load_hook /^vm_add>
+
+=item 4 C</set uberprompt_unload_hook /^vm_del>
+
+=back
+
+For I<left-aligned> items (before the prompt):
+
+=over 4
+
+=item 1 C</alias vm_add /^statusbar prompt add -before prompt -alignment left vim_mode>
+
+=item 2 C</alias vm_del /^statusbar prompt remove vim_mode>
+
+=item 3 C</set uberprompt_load_hook /^vm_add>
+
+=item 4 C</set uberprompt_unload_hook /^vm_del>
+
+=back
+
+If you wish to add both C<vim_mode> and C<vim_windows> items, replace steps 1 and 2
+above with the following (right-aligned):
+
+=over 4
+
+=item 1 C</alias vm_add /^eval /^statusbar prompt add -after input -alightment right vim_mode ; /^statusbar prompt add -after input -alignment right vim_windows>
+
+=item 2 C</alias vm_del /^eval /^statusbar prompt remove vim_mode ; /^statusbar prompt remove vim_windows>
+
+=back
+
+and then complete stages 3 and 4 as above. Replace the C<-after> and C<-alignment>
+to suit your location preferences.
+
+B<Note:> It is also possible to place the items between the prompt and input field,
+by specifying C<-after prompt> or C<-before input> as appropriate.
+
+=head3 Expando Variables
+
+Vim mode augments the existing Irssi expando (automatic variables) with two
+additional ones: C<$vim_cmd_mode> and C<$vim_wins>.
+
+C<$vim_cmd_mode> is the equivalent of the C<vim_mode> statusbar item, and
+C<$vim_wins> is the counterpart of C<vim_windows>.
+
+They can be added to your theme, or inserted into your uberprompt using
+a command such as:
+
+"C</set uberprompt_format [$vim_cmd_mode] $*$uber] >"
+
+=head3 FILE-BASED CONFIGURATION
+
+Additionally to the irssi settings described in L<settings|/SETTINGS>, vim_mode
+can be configured through an external configuration file named "vim_moderc"
+located in F<~/.irssi/vim_moderc>. If available it's loaded on startup and every
+supported ex-command is run. Its syntax is similar to "vimrc". To (re)load it
+while vim_mode is running use C<:so[urce]>.
+
+Currently Supported ex-commands:
+
+=over 4
+
+=item * C<:map>
+
+=back
+
+=head1 USAGE
+
+The following section is divided into the different modes as supported by Vim itself:
+
+=head2 COMMAND MODE
+
+It supports most commonly used command mode features:
+
+=over 2
+
+=item * Insert/Command mode.
+
+C<Esc> and C<Ctrl-C> enter command mode. C</set vim_mode_cmd_seq j> allows
+to use C<jj> as Escape (any other character can be used as well).
+
+=item * Cursor motion:
+
+C<h l 0 ^ $ E<lt>SpaceE<gt> E<lt>BSE<gt> f t F T>
+
+=item * History motion:
+
+C<j k gg G> C<gg> moves to the oldest (first) history line. C<G> without a
+count moves to the current input line, with a count it goes to the I<count-th>
+history line (1 is the oldest).
+
+=item * Cursor word motion:
+
+C<w b ge e W gE B E>
+
+=item * Word objects (only the following work yet):
+
+C<aw aW>
+
+=item * Yank and paste:
+
+ C<y p P>
+
+=item * Change and delete:
+
+C<c d>
+
+=item * Delete at cursor:
+
+C<x X>
+
+=item * Replace at cursor:
+
+C<r>
+
+=item * Insert mode:
+
+C<i a I A>
+
+=item * Switch case:
+
+C<~>
+
+=item * Repeat change:
+
+C<.>
+
+=item * Repeat
+
+C<ftFT: ; ,>
+
+=item * Registers:
+
+C<"a-"z "" "0 "* "+ "_> (black hole)
+
+=item * Line-wise shortcuts:
+
+C<dd cc yy>
+
+=item * Shortcuts:
+
+C<s S C D>
+
+=item * Scroll the scrollback buffer:
+
+C<Ctrl-E Ctrl-D Ctrl-Y Ctrl-U Ctrl-F Ctrl-B>
+
+=item * Switch to last active window:
+
+C<Ctrl-6/Ctrl-^>
+
+=item * Switch split windows:
+
+<Ctrl-W j Ctrl-W k>
+
+=item * Undo/Redo:
+
+C<u Ctrl-R>
+
+=back
+
+Counts and combinations work as well, e.g. C<d5fx> or C<3iabcE<lt>escE<gt>>. Counts also work with mapped ex-commands (see below), e.g. if you map C<gb> to do C<:bn>, then C<2gb> will switch to the second next buffer. Repeat also supports counts.
+
+=head3 REGISTERS
+
+=over 4
+
+=item * Appending to register with C<"A-"Z>
+
+=item * C<""> is the default yank/delete register.
+
+=item * C<"0> contains the last yank (if no register was specified).
+
+=item * The special registers C<"* "+> both contain irssi's internal cut-buffer.
+
+=back
+
+=head2 INSERT MODE
+
+The following insert mode mappings are supported:
+
+=over 4
+
+=item * Insert register content: Ctrl-R x (where x is the register to insert)
+
+=back
+
+=head2 EX-MODE
+
+Ex-mode (activated by C<:> in command mode) supports the following commands:
+
+=over 4
+
+=item * Command History:
+
+C<E<lt>uparrowE<gt>> - cycle backwards through history
+
+C<E<lt>downarrowE<gt>> - cycle forwards through history
+
+C<:eh> - show ex history
+
+=item * Switching buffers:
+
+C<:[N]b [N]> - switch to channel number
+
+C<:b#> - switch to last channel
+
+C<:b> E<lt>partial-channel-nameE<gt>
+
+C<:b> <partial-server>/<partial-channel>
+
+C<:buffer {args}> (same as C<:b>)
+
+C<:[N]bn[ext] [N]> - switch to next window
+
+C<:[N]bp[rev] [N]> - switch to previous window
+
+=item * Close window:
+
+C<:[N]bd[elete] [N]>
+
+=item * Display windows:
+
+C<:ls>, C<:buffers>
+
+=item * Display registers:
+
+C<:reg[isters] {args}>, C<:di[splay] {args}>
+
+=item * Display undolist:
+
+C<:undol[ist]> (mostly used for debugging)
+
+=item * Source files:
+
+C<:so[urce]> - only sources vim_moderc at the moment,
+ F<{file}> not supported
+
+=item * Mappings:
+
+C<:map> - display custom mappings
+
+=item * Saving mappings:
+
+C<:mkv[imrc][!]> - like in Vim, but [file] not supported
+
+=item * Substitution:
+
+C<:s///> - I<i> and I<g> are supported as flags, only C<///> can be used as
+eparator, and it uses Perl regex syntax instead of Vim syntax.
+
+=item * Settings:
+
+C<:se[t]> - display all options
+
+C<:se[t] {option}> - display all matching options
+
+C<:se[t] {option} {value}> - change option to value
+
+=back
+
+=head3 MAPPINGS
+
+=head4 Commands
+
+=over 4
+
+=item * C<:map {lhs}> - display mappings starting with {lhs}
+
+=item * C<:map {lhs} {rhs}> - add mapping
+
+=item * C<:unm[ap] {lhs}> - remove custom mapping
+
+=back
+
+=head4 Parameters
+
+I<{lhs}> is the key combination to be mapped, I<{rhs}> the target. The
+C<E<lt>E<gt>> notation is used
+
+(e.g. C<E<lt>C-FE<gt>> is I<Ctrl-F>), case is ignored.
+ Supported C<E<lt>E<gt>> keys are:
+
+=over 4
+
+=item * C<E<lt>C-AE<gt>> - C<E<lt>C-ZE<gt>>,
+
+=item * C<E<lt>C-^E<gt>>, C<E<lt>C-6E<gt>>
+
+=item * C<E<lt>SpaceE<gt>>
+
+=item * C<E<lt>CRE<gt>> - Enter
+
+=item * C<E<lt>BSE<gt>> - Backspace
+
+=item * C<E<lt>NopE<gt>> - No-op (Do Nothing).
+
+=back
+
+Mapping ex-mode and irssi commands is supported. When mapping ex-mode commands
+the trailing C<E<lt>CrE<gt>> is not necessary. Only default mappings can be used
+in I<{rhs}>.
+
+Examples:
+
+=over 4
+
+=item * C<:map w W> - to remap w to work like W
+
+=item * C<:map gb :bnext> - to map gb to call :bnext
+
+=item * C<:map gB :bprev>
+
+=item * C<:map g1 :b 1> - to map g1 to switch to buffer 1
+
+=item * C<:map gb :b> - to map gb to :b, 1gb switches to buffer 1, 5gb to 5
+
+=item * C<:map E<lt>C-LE<gt> /clear> - map Ctrl-L to irssi command /clear
+
+=item * C<:map E<lt>C-GE<gt> /window goto 1>
+
+=item * C<:map E<lt>C-EE<gt> <Nop>> - disable E<lt>C-EE<gt>, it does nothing now
+
+=item * C<:unmap E<lt>C-EE<gt>> - restore default behavior of C<E<lt>C-EE<gt>>
+after disabling it
+
+=back
+
+Note that you must use C</> for irssi commands (like C</clear>), the current value
+of Irssi's cmdchars does B<not> work! This is necessary do differentiate between
+ex-commands and irssi commands.
+
+=head2 SETTINGS
+
+The settings are stored as irssi settings and can be set using C</set> as usual
+(prepend C<vim_mode_> to setting name) or using the C<:set> ex-command. The
+following settings are available:
+
+=over 4
+
+=item * utf8 - Support UTF-8 characters, boolean, default on
+
+=item * debug - Enable debug output, boolean, default off
+
+=item * cmd_seq - Char that when double-pressed simulates C<E<lt>EscE<gt>>, string, default '' (disabled)
+
+=item * start_cmd - Start every line in command mode, boolean, default off
+
+=item * max_undo_lines - Sze of the undo buffer. Integer, default 50 items.
+
+=item * ex_history_size - Number of items stored in the ex-mode history. Integer, default 100.
+
+=item * prompt_leading_space - Ddetermines whether ex mode prepends a space to the displayed input. Boolean, default on
+
+=back
+
+In contrast to irssi's settings, C<:set> accepts 0 and 1 as values for boolean
+settings, but only vim_mode's settings can be set/displayed.
+
+Examples:
+
+ :set cmd_seq=j # set cmd_seq to j
+ :set cmd_seq= # disable cmd_seq
+ :set debug=on # enable debug
+ :set debug=off # disable debug
+
+=head1 SUPPORT

+considered a bug and reported.

+How the input system for vim_mode should work.
+=============================================
+
+* insert mode mappings
+* normal (command) mode mappings
+* timeout for ambiguous mappings
+** but support for no timeout for some mappings (like Ctrl-R in insert mode)
+* maybe 'timeout' and 'ttimeout' settings (and 'timeoutlen' and 'ttimeoutlen')
+* partial commands/mappings (like :map a :b a which inserts ex mode and
+* displays :b a there without running any command)
+* support for mappings entering insert mode: :map gX itexthere<esc> (also without esc!)
+** (.) (repeat) for all (most) commands
+* more general command order: 3"ap doesn't work but "a3p does
+* arbitrary mappings, like 3dwjjihi<esc>10G (at the moment even :map Y y$ doesn't work)
+* support to disable mappings temporarily (:set paste, 'pastetoggle')
+* (better) support multiple bindings for the same action (especially <BS> and <C-H>)
+* unmapping of internal mappings (for example <C-C> to <Nop> as it's also used for colors in irssi)
+* better approach to detecting single ESC push (compared to F-keys or meta-* keys)
+
+We base the input model on a simple state machine.
+It can exist in any of 4 (5) states:
+ - insert mode
+ - insert escape mode
+ a transitional mode to distingush that we've received an escape char.
+ - command mode
+ - ex mode
+ - visual mode (can be mostly ignored for now, until I sort my overlays stuff
+ out)
+
+to swap between these modes, there are various bindings available.
+The most challenging is going from insert -> command. Typically this is done
+by a single push of the <esc> key, but C-c and <jj> are both alternatives that
+people use.
+
+The single entrypoint we have into the input system is detecting keystrokes.
+when a 'gui key pressed' signal is fired, we can receive, process and interrupt
+it such that it never gets passed to irssi proper.
+
+in order to detect single <esc> presses from their meta comrades, we operate
+as the following:
+
+if (key == 27) {
+ mode = insert_escape
+ add_timeout(short, check_escape_buffer)
+} elsif (mode == insert_escape) {
+ insert(key, escape_buffer)
+} else {
+ # do nothing
+}
+
+sub check_escape_buffer {
+# when the timeout fires, we can assume that only meta-keys would be fast enough
+# to insert additional characters into the buffer. In which case, we replay
+# them and clear the buffer.
+ mode = insert_mode;
+# if the buffer is otherwise empty, we have received a single escape press.
+ mode = command_mode;
+}

-# A script to emulate some of the vi(m) features for the Irssi inputline.
-#
-# It should work fine with at least 0.8.12 and later versions. However some
-# features are disabled in older versions (see below for details). Perl >=
-# 5.8.1 is recommended for UTF-8 support (which can be disabled if necessary).
-# Please report bugs in older versions as well, we'll try to fix them.
-#
-# Any behavior different from Vim (unless explicitly documented) should be
-# considered a bug and reported.
-#
-# NOTE: This script is still under heavy development, and there may be bugs.
-# Please submit reproducible sequences to the bug-tracker at:
-# http://github.com/shabble/irssi-scripts/issues
-#
-# or contact rudi_s or shabble on irc.freenode.net (#irssi and #irssi_vim)
-#
-#
-# Features:
-#
-# It supports most commonly used command mode features:
-#
-# * Insert/Command mode. Escape and Ctrl-C enter command mode.
-# /set vim_mode_cmd_seq j allows to use jj as Escape (any other character
-# can be used as well).
-# * Cursor motion: h l 0 ^ $ <Space> <BS> f t F T
-# * History motion: j k gg G
-# gg moves to the oldest (first) history line.
-# G without a count moves to the current input line, with a count it goes to
-# the count-th history line (1 is the oldest).
-# * Cursor word motion: w b ge e W gE B E
-# * Word objects (only the following work yet): aw aW
-# * Yank and paste: y p P
-# * Change and delete: c d
-# * Delete at cursor: x X
-# * Replace at cursor: r
-# * Insert mode: i a I A
-# * Switch case: ~
-# * Repeat change: .
-# * Repeat ftFT: ; ,
-# * Registers: "a-"z "" "0 "* "+ "_ (black hole)
-# Appending to register with "A-"Z
-# "" is the default yank/delete register.
-# "0 contains the last yank (if no register was specified).
-# The special registers "* "+ contain both irssi's cut-buffer.
-# * Line-wise shortcuts: dd cc yy
-# * Shortcuts: s S C D
-# * Scroll the scrollback buffer: Ctrl-E Ctrl-D Ctrl-Y Ctrl-U Ctrl-F Ctrl-B
-# * Switch to last active window: Ctrl-6/Ctrl-^
-# * Switch split windows: Ctrl-W j Ctrl-W k
-# * Undo/Redo: u Ctrl-R
-#
-# Counts and combinations work as well, e.g. d5fx or 3iabc<esc>. Counts also
-# work with mapped ex-commands (see below), e.g. if you map gb to do :bn, then
-# 2gb will switch to the second next buffer.
-# Repeat also supports counts.
-#
-# The following insert mode mappings are supported:
-#
-# * Insert register content: Ctrl-R x (where x is the register to insert)
-#
-# Ex-mode supports (activated by : in command mode) the following commands:
-#
-# * Switching buffers: :[N]b [N] - switch to channel number
-# :b# - switch to last channel
-# :b <partial-channel-name>
-# :b <partial-server>/<partial-channel>
-# :buffer {args} (same as :b)
-# :[N]bn[ext] [N] - switch to next window
-# :[N]bp[rev] [N] - switch to previous window
-# * Close window: :[N]bd[elete] [N]
-# * Display windows: :ls :buffers
-# * Display registers: :reg[isters] {args} :di[splay] {args}
-# * Display undolist: :undol[ist] (mostly used for debugging)
-# * Source files :so[urce] - only sources vim_moderc at the moment,
-# {file} not supported
-# * Mappings: :map - display custom mappings
-# :map {lhs} - display mappings starting with {lhs}
-# :map {lhs} {rhs} - add mapping
-# :unm[ap] {lhs} - remove custom mapping
-# * Save mappings: :mkv[imrc][!] - like in Vim, but [file] not supported
-# * Substitute: :s/// - i and g are supported as flags, only /// can be
-# used as separator, uses Perl regex instead of
-# Vim regex
-# * Settings: :se[t] - display all options
-# :se[t] {option} - display all matching options
-# :se[t] {option} {value} - change option to value
-#
-#
-# Mappings:
-#
-# {lhs} is the key combination to be mapped, {rhs} the target. The <> notation
-# is used (e.g. <C-F> is Ctrl-F), case is ignored. Supported <> keys:
-# <C-A>-<C-Z>, <C-^>, <C-6>, <Space>, <CR>, <BS>, <Nop>. Mapping ex-mode and
-# irssi commands is supported. When mapping ex-mode commands the trailing <Cr>
-# is not necessary. Only default mappings can be used in {rhs}.
-# Examples:
-# :map w W - to remap w to work like W
-# :map gb :bnext - to map gb to call :bnext
-# :map gB :bprev
-# :map g1 :b 1 - to map g1 to switch to buffer 1
-# :map gb :b - to map gb to :b, 1gb switches to buffer 1, 5gb to 5
-# :map <C-L> /clear - map Ctrl-L to irssi command /clear
-# :map <C-G> /window goto 1
-# :map <C-E> <Nop> - disable <C-E>, it does nothing now
-# :unmap <C-E> - restore default behavior of <C-E> after disabling it
-#
-# Note that you must use / for irssi commands (like /clear), the current value
-# of cmdchars does _not_ work! This is necessary do differentiate between
-# ex-commands and irssi commands.
-#
-#
-# Settings:
-#
-# The settings are stored as irssi settings and can be set using /set as usual
-# (prepend vim_mode_ to setting name) or using the :set ex-command. The
-# following settings are available:
-#
-# * utf8: support UTF-8 characters, boolean, default on
-# * debug: enable debug output, boolean, default off
-# * cmd_seq: char that when double-pressed simulates <esc>, string, default ''
-# * start_cmd: start every line in command mode, boolean, default off
-#
-# In contrast to irssi's settings, :set accepts 0 and 1 as values for boolean
-# settings, but only vim_mode's settings can be set/displayed.
-# Examples:
-# :set cmd_seq=j # set cmd_seq to j
-# :set cmd_seq= # disable cmd_seq
-# :set debug=on # enable debug
-# :set debug=off # disable debug
-#
-#
-# The following statusbar items are available:
-#
-# * vim_mode: displays current mode
-# * vim_windows: displays windows selected with :b
-#
-#
-# Configuration
-#
-# Additionally to the irssi settings described above vim_mode can be
-# configured through an external configuration file named "vim_moderc" located
-# in ~/.irssi/vim_moderc. If available it's loaded on startup and every
-# supported ex-command is run. It's syntax is similar to "vimrc". To (re)load
-# it while vim_mode is running use :so[urce].
-#
-# Supported ex-commands:
-#
-# * :map
-#
-#
-# Installation:
-#
-# As always copy the script into .irssi/scripts and load it with
-# /script load # vim_mode.pl
-#
-# Use the following command to get a statusbar item that shows which mode
-# you're in.
-#
-# /statusbar window add vim_mode
-#
-# And the following to let :b name display a list of matching channels
-#
-# /statusbar window add vim_windows
-#
-#
-# Dependencies:
-#
-# For proper :ex mode support, requires the installation of uberprompt.pl
-# Uberprompt can be downloaded from:
-#
-# http://github.com/shabble/irssi-scripts/raw/master/prompt_info/uberprompt.pl
-#
-# and follow the instructions at the top of that file for installation.
-#
-# If you don't need Ex-mode, you can run vim_mode.pl without the
-# uberprompt.pl script, but it is recommended.
-#
-#
-# Irssi requirements:
-#
-# 0.8.12 and above should work fine. However the following features are
-# disabled in irssi < 0.8.13:
-#
-# * j k (only with count, they work fine without count in older versions)
-# * gg G
-#
-#
-# Known bugs:
-#
-# * count before register doesn't work: e.g. 3"ap doesn't work, but "a3p does
-# * mapping an incomplete ex-command doesn't open the ex-mode with the partial
-# command (e.g. :map gb :b causes an error instead of opening the ex-mode
-# and displaying :b<cursor>)
-# * undo/redo positions are mostly wrong
-#
-#
-# TODO:
-# * History:
-# * /,?,n,N to search through history (like history_search.pl)
-# * Window switching (:b)
-# * Tab completion of window(-item) names
-# * non-sequential matches(?)
-#
-# WONTFIX - things we're not ever likely to do
-# * Macros
-#
-# THANKS:
-#
-# * estragib: a lot of testing and many bug reports and feature requests
-# * iaj: testing

+=head1 NAME
+
+vim_mode.pl
+
+=head1 DESCRIPTION
+
+An Irssi script to emulate some of the vi(m) features for the Irssi inputline.
+
+=head1 INSTALLATION
+
+Copy into your F<~/.irssi/scripts/> directory and load with
+C</SCRIPT LOAD vim_mode.pl>. You may wish to have it autoload in one of the
+L<usual ways|https://github.com/shabble/irssi-docs/wiki/Guide#Autorunning_Scripts>.
+
+=head2 DEPENDENCIES
+
+For proper :ex mode support, vim-mode requires the installation of F<uberprompt.pl>
+Uberprompt can be downloaded from:
+
+L<https://github.com/shabble/irssi-scripts/raw/master/prompt_info/uberprompt.pl>
+
+and follow the instructions at the top of that file for installation.
+
+If you don't need Ex-mode, you can run vim_mode.pl without the
+uberprompt.pl script, but it is strongly recommended that you use it.
+
+=head3 Irssi requirements
+
+0.8.12 and above should work fine. However the following features are
+disabled in irssi < 0.8.13:
+
+=over 4
+
+=item * C<j> C<k> (only with count, they work fine without count in older versions)
+
+=item * C<gg>, C<G>
+
+=back
+
+It is intended to work with at Irssi 0.8.12 and later versions. However some
+features are disabled in older versions (see below for details).
+
+Perl >= 5.8.1 is recommended for UTF-8 support (which can be disabled if
+necessary). Please report bugs in older versions as well, we'll try to fix
+them. Later versions of Perl are also faster, which is probably beneficial
+to a script of this size and complexity.
+
+=head2 SETUP
+
+Vim Mode provides certain feedback to the user, such as the currently active
+mode (command, insert, ex), and if switching buffers, which buffer(s) currently
+match the search terms.
+
+There are two ways to go about displaying this information, as described in
+the following sections:
+
+=head3 Statusbar Items
+
+Run the following command to add a statusbar item that shows which mode
+you're in.
+
+C</statusbar window add vim_mode>
+
+And the following to let C<:b [str]> display a list of channels matching your
+search string.
+
+C</statusbar window add vim_windows>
+
+B<Note:> Remember to C</save> after adding these statusbar items to make them
+permanent.
+
+B<Note:> If you would rather have these statusbar items on your prompt
+line rather than thte window statusbar, please follow these steps.
+
+For technical reasons, I<uberprompt> must occasionally call C</statusbar prompt
+reset>, which will remove or deactivate any manually added items on the prompt
+statusbar. To get around this, uberprompt provides two command hooks,
+C<uberprompt_load_hook> and C<uberprompt_unload_hook>. Both of these settings
+can contain one (or more, using C</EVAL>) commands to be executed when the prompt
+is enabled and disabled, respectively.
+
+See the L<uberprompt documentation|https://github.com/shabble/irssi-scripts/blob/master/prompt_info/README.pod> for further details.
+
+For I<right-aligned> items (that is, after the input field:
+
+=over 4
+
+=item 1 C</alias vm_add /^statusbar prompt add -after input -alignment right vim_mode>
+
+=item 2 C</alias vm_del /^statusbar prompt remove vim_mode>
+
+=item 3 C</set uberprompt_load_hook /^vm_add>
+
+=item 4 C</set uberprompt_unload_hook /^vm_del>
+
+=back
+
+For I<left-aligned> items (before the prompt):
+
+=over 4
+
+=item 1 C</alias vm_add /^statusbar prompt add -before prompt -alignment left vim_mode>
+
+=item 2 C</alias vm_del /^statusbar prompt remove vim_mode>
+
+=item 3 C</set uberprompt_load_hook /^vm_add>
+
+=item 4 C</set uberprompt_unload_hook /^vm_del>
+
+=back
+
+If you wish to add both C<vim_mode> and C<vim_windows> items, replace steps 1 and 2
+above with the following (right-aligned):
+
+=over 4
+
+=item 1 C</alias vm_add /^eval /^statusbar prompt add -after input -alightment right vim_mode ; /^statusbar prompt add -after input -alignment right vim_windows>
+
+=item 2 C</alias vm_del /^eval /^statusbar prompt remove vim_mode ; /^statusbar prompt remove vim_windows>
+
+=back
+
+and then complete stages 3 and 4 as above. Replace the C<-after> and C<-alignment>
+to suit your location preferences.
+
+B<Note:> It is also possible to place the items between the prompt and input field,
+by specifying C<-after prompt> or C<-before input> as appropriate.
+
+=head3 Expando Variables
+
+Vim mode augments the existing Irssi expando (automatic variables) with two
+additional ones: C<$vim_cmd_mode> and C<$vim_wins>.
+
+C<$vim_cmd_mode> is the equivalent of the C<vim_mode> statusbar item, and
+C<$vim_wins> is the counterpart of C<vim_windows>.
+
+They can be added to your theme, or inserted into your uberprompt using
+a command such as:
+
+"C</set uberprompt_format [$vim_cmd_mode] $*$uber] >"
+
+=head3 FILE-BASED CONFIGURATION
+
+Additionally to the irssi settings described in L<settings|/SETTINGS>, vim_mode
+can be configured through an external configuration file named "vim_moderc"
+located in F<~/.irssi/vim_moderc>. If available it's loaded on startup and every
+supported ex-command is run. Its syntax is similar to "vimrc". To (re)load it
+while vim_mode is running use C<:so[urce]>.
+
+Currently Supported ex-commands:
+
+=over 4
+
+=item * C<:map>
+
+=back
+
+=head1 USAGE
+
+The following section is divided into the different modes as supported by Vim itself:
+
+=head2 COMMAND MODE
+
+It supports most commonly used command mode features:
+
+=over 2
+
+=item * Insert/Command mode.
+
+C<Esc> and C<Ctrl-C> enter command mode. C</set vim_mode_cmd_seq j> allows
+to use C<jj> as Escape (any other character can be used as well).
+
+=item * Cursor motion:
+
+C<h l 0 ^ $ E<lt>SpaceE<gt> E<lt>BSE<gt> f t F T>
+
+=item * History motion:
+
+C<j k gg G> C<gg> moves to the oldest (first) history line. C<G> without a
+count moves to the current input line, with a count it goes to the I<count-th>
+history line (1 is the oldest).
+
+=item * Cursor word motion:
+
+C<w b ge e W gE B E>
+
+=item * Word objects (only the following work yet):
+
+C<aw aW>
+
+=item * Yank and paste:
+
+ C<y p P>
+
+=item * Change and delete:
+
+C<c d>
+
+=item * Delete at cursor:
+
+C<x X>
+
+=item * Replace at cursor:
+
+C<r>
+
+=item * Insert mode:
+
+C<i a I A>
+
+=item * Switch case:
+
+C<~>
+
+=item * Repeat change:
+
+C<.>
+
+=item * Repeat
+
+C<ftFT: ; ,>
+
+=item * Registers:
+
+C<"a-"z "" "0 "* "+ "_> (black hole)
+
+=item * Line-wise shortcuts:
+
+C<dd cc yy>
+
+=item * Shortcuts:
+
+C<s S C D>
+
+=item * Scroll the scrollback buffer:
+
+C<Ctrl-E Ctrl-D Ctrl-Y Ctrl-U Ctrl-F Ctrl-B>
+
+=item * Switch to last active window:
+
+C<Ctrl-6/Ctrl-^>
+
+=item * Switch split windows:
+
+<Ctrl-W j Ctrl-W k>
+
+=item * Undo/Redo:
+
+C<u Ctrl-R>
+
+=back
+
+Counts and combinations work as well, e.g. C<d5fx> or C<3iabcE<lt>escE<gt>>. Counts also work with mapped ex-commands (see below), e.g. if you map C<gb> to do C<:bn>, then C<2gb> will switch to the second next buffer. Repeat also supports counts.
+
+=head3 REGISTERS
+
+=over 4
+
+=item * Appending to register with C<"A-"Z>
+
+=item * C<""> is the default yank/delete register.
+
+=item * C<"0> contains the last yank (if no register was specified).
+
+=item * The special registers C<"* "+> both contain irssi's internal cut-buffer.
+
+=back
+
+=head2 INSERT MODE
+
+The following insert mode mappings are supported:
+
+=over 4
+
+=item * Insert register content: Ctrl-R x (where x is the register to insert)
+
+=back
+
+=head2 EX-MODE
+
+Ex-mode (activated by C<:> in command mode) supports the following commands:
+
+=over 4
+
+=item * Command History:
+
+C<E<lt>uparrowE<gt>> - cycle backwards through history
+
+C<E<lt>downarrowE<gt>> - cycle forwards through history
+
+C<:eh> - show ex history
+
+=item * Switching buffers:
+
+C<:[N]b [N]> - switch to channel number
+
+C<:b#> - switch to last channel
+
+C<:b> E<lt>partial-channel-nameE<gt>
+
+C<:b> <partial-server>/<partial-channel>
+
+C<:buffer {args}> (same as C<:b>)
+
+C<:[N]bn[ext] [N]> - switch to next window
+
+C<:[N]bp[rev] [N]> - switch to previous window
+
+=item * Close window:
+
+C<:[N]bd[elete] [N]>
+
+=item * Display windows:
+
+C<:ls>, C<:buffers>
+

+
+=over 4
+
+=item * C<:map {lhs}> - display mappings starting with {lhs}
+
+=item * C<:map {lhs} {rhs}> - add mapping
+
+=item * C<:unm[ap] {lhs}> - remove custom mapping
+
+=back
+
+=head4 Parameters
+
+I<{lhs}> is the key combination to be mapped, I<{rhs}> the target. The
+C<E<lt>E<gt>> notation is used
+
+(e.g. C<E<lt>C-FE<gt>> is I<Ctrl-F>), case is ignored.
+ Supported C<E<lt>E<gt>> keys are:
+
+=over 4
+
+=item * C<E<lt>C-AE<gt>> - C<E<lt>C-ZE<gt>>,
+
+=item * C<E<lt>C-^E<gt>>, C<E<lt>C-6E<gt>>
+
+=item * C<E<lt>SpaceE<gt>>
+
+=item * C<E<lt>CRE<gt>> - Enter
+
+=item * C<E<lt>BSE<gt>> - Backspace
+
+=item * C<E<lt>NopE<gt>> - No-op (Do Nothing).
+
+=back
+
+Mapping ex-mode and irssi commands is supported. When mapping ex-mode commands
+the trailing C<E<lt>CrE<gt>> is not necessary. Only default mappings can be used
+in I<{rhs}>.
+
+Examples:
+
+=over 4
+
+=item * C<:map w W> - to remap w to work like W
+
+=item * C<:map gb :bnext> - to map gb to call :bnext
+
+=item * C<:map gB :bprev>
+
+=item * C<:map g1 :b 1> - to map g1 to switch to buffer 1
+
+=item * C<:map gb :b> - to map gb to :b, 1gb switches to buffer 1, 5gb to 5
+
+=item * C<:map E<lt>C-LE<gt> /clear> - map Ctrl-L to irssi command /clear
+
+=item * C<:map E<lt>C-GE<gt> /window goto 1>
+
+=item * C<:map E<lt>C-EE<gt> <Nop>> - disable E<lt>C-EE<gt>, it does nothing now
+
+=item * C<:unmap E<lt>C-EE<gt>> - restore default behavior of C<E<lt>C-EE<gt>>
+after disabling it
+
+=back
+
+Note that you must use C</> for irssi commands (like C</clear>), the current value
+of Irssi's cmdchars does B<not> work! This is necessary do differentiate between
+ex-commands and irssi commands.
+
+=head2 SETTINGS
+
+The settings are stored as irssi settings and can be set using C</set> as usual
+(prepend C<vim_mode_> to setting name) or using the C<:set> ex-command. The
+following settings are available:
+
+=over 4
+
+=item * utf8 - Support UTF-8 characters, boolean, default on
+
+=item * debug - Enable debug output, boolean, default off
+
+=item * cmd_seq - Char that when double-pressed simulates C<E<lt>EscE<gt>>, string, default '' (disabled)
+
+=item * start_cmd - Start every line in command mode, boolean, default off
+
+=item * max_undo_lines - Sze of the undo buffer. Integer, default 50 items.
+
+=item * ex_history_size - Number of items stored in the ex-mode history. Integer, default 100.
+
+=item * prompt_leading_space - Ddetermines whether ex mode prepends a space to the displayed input. Boolean, default on
+
+=back
+
+In contrast to irssi's settings, C<:set> accepts 0 and 1 as values for boolean
+settings, but only vim_mode's settings can be set/displayed.
+
+Examples:
+
+ :set cmd_seq=j # set cmd_seq to j
+ :set cmd_seq= # disable cmd_seq
+ :set debug=on # enable debug
+ :set debug=off # disable debug
+
+=head1 SUPPORT
+
+Any behavior different from Vim (unless explicitly documented) should be
+considered a bug and reported.
+
+B<NOTE:> This script is still under heavy development, and there may be bugs.
+Please submit reproducible sequences to the bug-tracker at:
+L<http://github.com/shabble/irssi-scripts/issues/new>
