== Objects ==
- liberator.plugins.libly.$U
- liberator.plugins.libly.Request
- liberator.plugins.libly.Response
- liberator.plugins.libly.Wedata
== Logger ==
getLogger(prefix):
log(msg, level), echo(msg, flg), echoerr(msg)
のメソッドを持つ logger インスタンスを取得します。
ログの書式は prefix + ': ' + yyyy/MM/dd + msg となります。
== Object Utility ==
extend(dst, src):
オブジェクトを拡張します。
A(iterable):
オブジェクトを配列にします。
around(obj, name, func):
obj がもつ name 関数を、func に置き換えます。
func は
function (next, args) {...}
という形で呼ばれます。
next はオリジナルの関数を呼び出すための関数、
args はオリジナルの引数列です。
next には引数を渡す必要はありません。
bind(obj, func):
func に obj を bind します。
func内からは this で obj が参照できるようになります。
eval(text):
Sandbox による、window.eval を極力利用するようにします。
Snadbox が利用できない場合は、unsafe な window の eval が直接利用されます。
evalJson(str, toRemove):
str を decode します。
toRemove が true の場合、文字列の前後を1文字削除します。
"(key:value)" 形式の場合などに true を指定して下さい。
dateFormat(dtm, fmt):
Date型インスタンスを、指定されたフォーマットで文字列に変換します。
fmt を省略した場合、"%y/%M/%d %h:%m:%s" となります。
runnable(generator):
gererator を実行し、再帰的に resume する為の引数を渡します。
== Browser ==
getSelectedString:
window の選択文字列を返却します。
getUserAndPassword(hostname, formSubmitURL, username):
login-manager から [username, password] を取得します。
引数の username が省略された場合、検索された 1件目を返却します。
データが存在しない場合は、null を返却します。
== System ==
readDirectory(path, fileter, func):
path で指定したディレクトリから、filter で指定された正規表現に match する場合、
func をファイル名を引数にコールバックします。
filter は Function を指定することも可能です。
== HTML, XML, DOM, E4X ==
pathToURL(a, baseURL, doc):
相対パスを絶対パスに変換します。
getHTMLFragment(html):
<html>※1</html>
※1 の文字列を取得します。
stripTags(str, tags):
str から tags で指定されたタグを取り除いて返却します。
tags は文字列、または配列で指定して下さい。
createHTMLDocument(str, xmlns):
引数 str より、HTMLFragment を作成します。
getFirstNodeFromXPath(xpath, context):
xpath を評価しオブジェクトをを返却します。
getNodesFromXPath(xpath, context, callback, thisObj):
xpath を評価し snapshot の配列を返却します。
xmlSerialize(xml):
xml を文字列化します。
xmlToDom(node, doc, nodes):
for vimperator1.2.
@see vimperator2.0pre util.
getElementPosition(elem):
elem の offset を返却します。
return {top: 0, left: 0}
