/**
* ==VimperatorPlugin==
* @name copy.js
* @description enable to copy strings from a template (like CopyURL+)
* @description-ja テンプレートから文字列のコピーを可能にします（CopyURL+みたなもの）
* @minVersion 1.1
* @author teramako teramako@gmail.com
* @version 0.5a
* ==/VimperatorPlugin==
*
* Usage:
* :copy {copyString} -> copy the argument replaced some certain string
* :copy! {expr} -> evaluate the argument and copy the result
*
* e.g.)
* :copy %TITLE% -> copied the title of the current page
* :copy title -> same as `:copy %TITLE%' by default
* :copy! liberator.version -> copy the value of liberator.version
*
* If non-argument, used `default'
*
* label: template name which is command argument
* value: copy string
* the certian string is replace to ...
* %TITTLE% -> to the title of the current page
* %URL% -> to the URL of the current page
* %SEL% -> to the string of selection
* %HTMLSEL% -> to the html string of selection
*
* map: key map (optional)
*
* custom: {function} or {Array} (optional)
* {function}:
* execute the function and copy return value, if specified.
*
* {Array}:
* replaced to the {value} by normal way at first.
* and replace words matched {Array}[0] in the replaced string to {Array}[1].
* {Array}[0] is string or regexp
* {Array}[1] is string or function
* see http://developer.mozilla.org/en/docs/Core_JavaScript_1.5_Reference:Global_Objects:String:replace
*
* The copy_templates is a string variable which can set on
* vimperatorrc as following.
*
* let copy_templates = "[{ label: 'titleAndURL', value: '%TITLE%\n%URL%' }, { label: 'title', value: '%TITLE%' }]"
*
* or your can set it using inline JavaScript.
*
* javascript <<EOM
* liberator.globalVariables.copy_templates = [
* { label: 'titleAndURL', value: '%TITLE%\n%URL%' },
* { label: 'title', value: '%TITLE%', map: ',y' },
* { label: 'anchor', value: '<a href="%URL%">%TITLE%</a>' },
* { label: 'selanchor', value: '<a href="%URL%" title="%TITLE%">%SEL%</a>' },
* { label: 'htmlblockquote', value: '<blockquote cite="%URL%" title="%TITLE%">%HTMLSEL%</blockquote>' }
* { label: 'ASIN', value: 'copy ASIN code from Amazon', custom: function(){return content.document.getElementById('ASIN').value;} },
* ];
* EOM
