如何设置的iTunes 11或洗牌的AppleScript通过重复模式 [英] How to set iTunes 11 in shuffle or repeat mode via applescript

问题描述

根据 http://dougscripts.com/通过AppleScript的设置随机播放和重复模式在iTunes 11被打破。

According to http://dougscripts.com/ setting shuffle and repeat modes via applescript is broken in iTunes 11.

根据这个 StackOverflow的答案洗牌现在是一个独立的播放列表设置。

According to this stackoverflow answer shuffle is now a playlist independent setting.

因此​​，我试图通过用户界面来设置随机值，无论是由iTunes的LCD杂交显示器或通过菜单栏。所有我能得到试图点击洗牌按钮/菜单项时，无论是在LCD区域或菜单栏是未知的UI指数的错误。 （我是新来的AppleScript）。

Thus, I tried to set the shuffle value via the UI, either by the LCD-ish display of iTunes or via the menu bar. All I could get was "unknown UI index" errors when trying to click the shuffle button/menu item, either in the LCD area or the menu bar. (I'm new to applescript).

如果一些你能想出一个方法来切换随机播放模式的上的iTunes 11 ，那将是巨大的。另外的我倒是preFER的解决方案基于菜单栏，而不是液晶显示器，因为洗牌按钮并不总是在后者可见。

If some of you could come up with a way to toggle shuffle mode on iTunes 11, that would be great. Also I'd prefer a solution based on the menu bar rather than the LCD display since the shuffle button is not always visible in the latter.

在理想情况下，我倒是preFER通过基于UI的解决方案一个基于语义的解决方案，但我不知道是否有可能（如iTunes 11的AppleScript库似乎是因为它过时何况在播放列表项的洗牌属性）。

Ideally, I'd prefer a semantic-based solution over a UI-based solution but I'm not sure if it's possible (iTunes 11 applescript library seems to be outdate since it mention a "shuffle" property for "playlists" items).

推荐答案

我喜欢约翰·绍尔的方法这么多，我写我自己的一些干将/使用他的方法这些属性setter方法​​。它的作品很好，因为你没有使用它们之前激活的iTunes。无论如何，我想我会发布他们他们的帮助，任何人的情况下。您将获得或使用如下的类型（菜单项名称为蓝本），其值设置：

I liked John Sauer's approach so much I wrote myself some getters/setters for these properties using his approach. It's works well because you do not have to activate iTunes before using them. Anyway, I thought I'd post them in case they're of help to anyone. You will get or set their values using the "types" (modeled after the menu item names) as follows:

重复的类型是关，全部或一。

Repeat types are "Off", "All", or "One".

随机播放类型是关，通过歌，通过相册，或按分组

Shuffle types are "Off", "By Songs", "By Albums", or "By Groupings"

on getRepeatType() -- the return value is a string: Off/All/One
    tell application "System Events"
        tell process "iTunes"
            set menuItems to menu items of menu bar 1's menu bar item "Controls"'s menu 1's menu item "Repeat"'s menu 1
            set currentChoice to "unknown"
            repeat with anItem in menuItems
                try
                    set theResult to value of attribute "AXMenuItemMarkChar" of anItem
                    if theResult is not "" then
                        set currentChoice to name of anItem
                        exit repeat
                    end if
                end try
            end repeat
        end tell
    end tell
    return currentChoice
end getRepeatType

on setRepeatType(repeatType) -- repeatType is a string: Off/All/One
    set currentValue to my getRepeatType()
    ignoring case
        if currentValue is not repeatType then
            tell application "System Events" to tell process "iTunes"'s menu bar 1's menu bar item "Controls"'s menu 1's menu item "Repeat"'s menu 1
                if repeatType is "all" then
                    perform action "AXPress" of menu item "All"
                else if repeatType is "one" then
                    perform action "AXPress" of menu item "One"
                else
                    perform action "AXPress" of menu item "Off"
                end if
            end tell
        end if
    end ignoring
end setRepeatType

on getShuffleType() -- the return value is a string: Off/By Songs/By Albums/By Groupings
    tell application "System Events"
        tell process "iTunes"
            set menuItems to menu items of menu bar 1's menu bar item "Controls"'s menu 1's menu item "Shuffle"'s menu 1
            set onOffItemName to name of item 1 of menuItems
        end tell
    end tell

    -- is shuffle off
    ignoring case
        if onOffItemName contains " on " then return "Off"
    end ignoring

    -- shuffle is on so find how we are shuffling
    set currentChoice to "Unknown"
    tell application "System Events"
        tell process "iTunes"
            repeat with i from 2 to count of menuItems
                set anItem to item i of menuItems

                    set theResult to value of attribute "AXMenuItemMarkChar" of anItem

                        set currentChoice to name of anItem

    end tell
    return currentChoice

on setShuffleType(shuffleType) -- shuffleType is a string:  Off/By Songs/By Albums/By Groupings
    set currentValue to my getShuffleType()

    script subs
        on toggleShuffleOnOff()
            tell application "System Events" to perform action "AXPress" of (first menu item of process "iTunes"'s menu bar 1's menu bar item "Controls"'s menu 1's menu item "Shuffle"'s menu 1 whose name ends with "Shuffle")

    end script

    ignoring case
        if shuffleType contains "off" then -- we have to make sure it's off
            if currentValue does not contain "off" then subs's toggleShuffleOnOff()
