// Vimperator plugin: uaSwitch

// Require: User Agent Switcher - https://addons.mozilla.org/firefox/addon/59
// Usage:
//   :ua MyUserAgent     - set user agent named MyUserAgent.
//   :ua Default         - reset user agent to default.
//   :ua!                - open user agent switcher setting dialog.
//   :ua                 - show current user agent.

 * ==VimperatorPlugin==
 * @name           feedSomeKeys 2
 * @description    feed some defined key events into the Web content
 * @description-ja 定義したkeyイベントをWebページ側へ送ってあげます
 * @author         teramako teramako@gmail.com
 * @version        2.0a
 * ==/VimperatorPlugin==
 *
 * 英語での説明を放棄する
 *
 * XXX: feedSomeKeys.js の改良版仕様を変更したのでフォーク
 *
 * keyイベント(正確にはkepressイベント)をWebコンテンツ側へ送る事を可能にするプラグイン
 * Gmailとかlivedoor ReaderとかGreasemonkeyでキーを割り当てている場合に活躍するでしょう。
 * それ以外の場面ではむしろ邪魔になる諸刃の剣
 *
 * :f[eed]map lhs [...]             -> lhsのキーマップをそのままWebコンテンツへ
 * :f[eed]map lhs,[num]rhs [...]    -> lhsのキーマップをrhsへ変換してWebコンテンツへ
 *                                     [num]はフレームの番号(省略時はトップウィンドウへイベントが送られる)
 * :f[eed]map -d[epth] {num} ...    -> {num}はフレームの番号で :fmap lhs1,{num}rhs1 lhs2,{num}rhs2 ... と同等
 *                                     Gmailの例を参照
 * :f[eed]map -v[key] ....          -> 仮想キーコードでイベントを送るように
 *
 * :fmapc
 * :feedmapclear            -> 全てを無に帰して元に戻す
 *
 * :f[eed]map! lhs ...      -> "!" をつけると、一旦すべてのfeedKeysを元に戻しての再定義
 *
 * autocmdと組み合わせる場合は
 * :autocmd LocationChange .* :fmapc
 * を最初に登録してください。でないと対象外のページに移ったときに設定が前のものを引きずることになります。
 *
 * また、下記設定例はvimperator 2.0pre用で1.2の場合は\を一つに削ってください。
 *
 * == LDR の場合 ==
 * :autocmd LocationChange .* :fmapc
 * :autocmd LocationChange reader\\.livedoor\\.com/reader :fmap j k s a p o v c <Space> <S-Space> z b < >
 *
 * とかやると幸せになれるかも。
 *
 * == Gmail の場合 ==
 * :autocmd LocationChange .* :fmapc
 * :autocmd LocationChange mail\\.google\\.com/mail :fmap -depth 4 c / j k n p o u e x s r a # [ ] z ? gi gs gt gd ga gc
 *
 * とかやると幸せになれるかもしれません。
 *
 * == Google Reader の場合 ==
 * :autocmd LocationChange .* :fmapc
 * :autocmd LocationChange www\\.google\\.co\\.jp/reader :fmap! -vkey j k n p m s t v A r S N P X O gh ga gs gt gu u / ?
 *
 * Greasemonkey LDRizeの場合などにも使用可
