== USAGE ==
Extended-hints mode ';m' to yank image URL and ';i' to save image are
available. These are default settings. You can change these by below
settings.
Ex-command ':downimageall' is also available. This is to download all
images of current page, but it effects heavy load to the server, you must
use carefully. We are NOT RESPONSIBLE for result of this command.
== SETTING ==
:image_extender_yank_key:
The key to yank image URL(default: 'm').
:image_extender_save_key:
The key to save image(default: 'i').
:image_extender_skip_prompt:
If this setted 'true', skip prompt to locate and name. Changing this value
will reflect dynamically. ':downimageall' command ignore this
setting(default: 'false').
== EXAMPLE ==
In .vimperatorrc
>||
image_extender_yank_key='g'
image_extender_save_key='e'
image_skip_prompt='true'
||<
In this settings, ';g' start extended-hints mode to yank image URL. ';e'
start it to save image, and prompt is not displayed at save operation.
]]></detail>
<detail lang="ja"><![CDATA[
== USAGE ==
画像の URL をヤンクする ';m' と 画像を保存する ';i' という拡張ヒントモードが使えるようになります。
これらはデフォルト設定です。後述する設定でキーを変更できます。
':downimageall' という ex コマンドも使えるようになります。
これは現在のページの画像をすべて保存するものですが、サーバに大きな負荷がかかるため注意して使ってください。
このコマンドの使用による結果は一切の責任を負いかねます。
== SETTING ==
:image_extender_yank_key:
画像 の URL をヤンクするキーです (デフォルト: 'm') 。
:image_extender_save_key:
画像を保存するキーです (デフォルト: 'i') 。
:image_extender_skip_prompt:
この値が 'true' の場合、保存する場所や名前を指定するダイアログは表示されません。
この値の変更は即座に反映されます。
':downimageall' コマンドはこの設定を無視します (デフォルト: 'false') 。
== EXAMPLE ==
.vimperatorrc の中で、
>||
image_extender_yank_key='g'
image_extender_save_key='e'
image_skip_prompt='true'
||<
と設定すると、 ';g' で画像の URL をヤンクする拡張ヒントモードが開始されます。
';e' で画像を保存しますが、その際ダイアログは表示されません。
