INTRODUCTION					*arpeggio-introduction*

*arpeggio* is a Vim plugin to define another type of |key-mapping| called
*arpeggio-key-mapping* -- it consists of 2 or more keys ({lhs}) and it will be
expanded to another key sequence ({rhs}) whenever all keys in {lhs} are
simultaneously pressed.  For example:
>
	Arpeggio inoremap jk  <Esc>
	" OR
	call arpeggio#map('i', '', 0, 'jk', '<Esc>')
<
With the above definition, you can input <Esc> in Insert mode by pressing "j"
and "k" simultaneously, while you can move the cursor by pressing "j" or "k"
solely.

The concept of this plugin is derived from Emacs' key-chord.el (*1), but there
are the following differences:

- Number of keys to be simultaneously pressed is unlimited.

- Custom delay for each key is supported (see |g:arpeggio_timeoutlens|).
  This is a generalization of space-chord.el (*2).

Requirements:
- Vim 7.2 or later

			If {lhs} is omitted, list all key mappings defined by
			|:Arpeggiomap| or others.


------------------------------------------------------------------------------
FUNCTIONS					*arpeggio-functions*

arpeggio#list({modes}, {options}, [{lhs}])	*arpeggio#list()*
			Function version of |:Arpeggiomap_l| and others.
			See |arpeggio#map()| for the details of arguments.

			For this function, {lhs} can be omitted or can be 0.
			If so, all arpeggio mappings defined in {modes} will
			be listed.

arpeggio#load()					*arpeggio#load()*
			Load this plugin if it is not loaded yet.  Otherwise,
			does nothing.  Call this function to ensure that
			|arpeggio-commands| are defined before you use one of
			them, especially, in your |vimrc|.

						*arpeggio#map()*
arpeggio#map({modes}, {options}, {remap-p}, {lhs}, {rhs})
			Function version of |:Arpeggiomap| and others.

			{modes}
				String.  Each character means one or more
				modes to define the given key mapping.  "n"
				means Normal mode, "v" means Visual mode and
				Select mode (the same as what |:vmap| does),
				and so forth.

			{options}
				String.  Each character means one of
				|:map-arguments|.  The meanings of characters
				are as follows:

				Char	Meaning ~
				b	<buffer>
				e	<expr>
				s	<silent>
				u	<unique>

				Other |:map-arguments| are not supported for
				arpeggio key mappings.

				Note that the meaning of <unique> is a bit
				differed as follows:

				- If a key in {lhs} is already mapped to
				  something other than a part of
				  |arpeggio-key-mapping|, an error will be
				  raised and defining of this mapping will be
				  aborted.

				- If {lhs} is already mapped to another
				  |arpeggio-key-mapping|, an error will be
				  raised and defining of this mapping will be
				  aborted.

			{remap-p}
				Number as a boolean.  True means that {rhs}
				will be remapped, and false means that {rhs}
				will not be remapped.

			{lhs}
				String.  This value must contain two or more
				keys.  Special keys such as <C-u> must be
				escaped with < and >, i.e., use '<C-u>' not
				"\<C-u>".

			{rhs}
				String.

arpeggio#unmap({modes}, {options}, {lhs})	*arpeggio#unmap()*
			Function version of |:Arpeggiounmap| and others.
			See |arpeggio#map()| for the details of arguments.


------------------------------------------------------------------------------
MAPPINGS					*arpeggio-mappings*

In the following description, {X} means a character in {lhs} which are used
for |:Arpeggiomap| and others.

{X}
			Mapped to internal stuffs.  Don't map {X} to anything.
			To customize the action for solely typed {X}, use
			|<Plug>(arpeggio-default:{X})| instead.

<Plug>(arpeggio-default:{X})			*<Plug>(arpeggio-default:{X})*
			Pseudo key sequence to customize the action whenever
			{X} is typed solely.  By default, this key sequence is
			mapped to {X} with no remapping.


------------------------------------------------------------------------------
VARIABLES					*arpeggio-variables*

g:arpeggio_timeoutlen	number  (default 40)	*g:arpeggio_timeoutlen*
			The time in milliseconds to determine whether typed
			keys are simultaneously pressed or not.

g:arpeggio_timeoutlens	Dictionary (default {})	*g:arpeggio_timeoutlens*
			Each key (in this dictionary) is a string of a key (on
			a keyboard), and each value is a number which means
			the same as |g:arpeggio_timeoutlen| but it is used
			only for the corresponding key.




==============================================================================
BUGS						*arpeggio-bugs*

- Not all keyboards have N-key rollover (*).  Though this plugin supports
  unlimited number of simultaneously pressed keys, 3 or more keys may not be
  inputted simultaneously.

  For keyboards which don't have N-key rollover, it's possible to emulate to
  simultaneously press 3 or more keys by pressing each key after another key
  in short time, i.e., arpeggio.

  (*) http://en.wikipedia.org/wiki/Rollover_(key)

- |arpeggio-key-mapping| may not be worked or may be conflicted with |@|
  and/or |key-mapping|.  Because recorded key sequence doesn't have any
  information about typing delay for each key.  So some keys may be treated as
  an arpeggio key mapping unexpectedly.

CHANGELOG					*arpeggio-changelog*

0.0.6	2010-04-20T12:24:42+09:00		*arpeggio-changelog-0.0.6*
	- Fix |arpeggio-commands| to behave the same as |:map| commands.  In
	  other words, " and keys after " in {rhs} for |arpeggio-commands| are
	  treated as a part of {rhs}.  Old versions don't behave so.
	- Fix minor bugs.
	- Revise the document a bit.
	- Revise additional syntax highlighting a bit.

0.0.5	2008-11-19T23:11:31+09:00		*arpeggio-changelog-0.0.5*
	- Remove the assumption on 'timeout' and 'ttimeout'.  Old version
	  assumes that "set timeout notimeout", but now their values can be
	  arbitrary.
	- Fix the bug that 'ttimeoutlen' can be interpreted as an unexpected
	  value because of the adjustment of 'timeout' and 'timeoutlen' for
	  arpeggio key mappings.

0.0.4	2008-11-10T02:38:07+09:00		*arpeggio-changelog-0.0.4*
	- Add syntax highlighting for |arpeggio-commands|.
	- Fix bugs of "noremap" version of |arpeggio-commands| such as
	  |:Arpeggionoremap| that {rhs} are remapped despite the meaning of
	  the commands.  (Thanks for id:ampmmn)

0.0.3	2008-11-09T10:37:46+09:00		*arpeggio-changelog-0.0.3*
	- Add |:Arpeggio|.
	- Support |:map-<unique>| for |arpeggio#map()| and other commands.
	- In |arpeggio#map()| and other commands, warn if a key in {lhs} is
	  already mapped to something other than a part of another
	  |arpeggio-key-mapping|.
	- Add custom 'timeoutlen' per key.  See |g:arpeggio_timeoutlens|.
	- Add a bit of completion for |arpeggio-commands|.

0.0.2	2008-11-07T22:16:51+09:00		*arpeggio-changelog-0.0.2*
	- Fix |:Arpeggionoremap| that allowed remapping but it should not do
	  so.  (Thanks for id:ampmmn)
	- Define |arpeggio-commands| and |arpeggio-variables| automatically
	  for interactive or other use.  (But you still have to call
	  |arpeggio#load()| to use them in vimrc.)

0.0.1	2008-11-06T09:34:19+09:00		*arpeggio-changelog-0.0.1*
	- Implement |arpeggio-commands|.
	- Add missing |arpeggio#list()|.
	- Revise minor stuffs.

0.0.0	2008-11-04T15:53:03+09:00		*arpeggio-changelog-0.0.0*
	- Initial version.
