如何在applescript中运行带参数的DiffMerge？

Question

理想情况下，我有以下输入：

set appId to "com.sourcegear.DiffMerge"
set path1 to "/tmp/file1.txt"
set path2 to "/tmp/file2.txt"

并且需要使用带有给定参数的appId来运行应用程序。

我知道如何使用appId运行这个应用程序，但它不能通过参数。

tell application id appId to activate

或者我可以运行应用程序并传递参数，但我不知道如何从appId获取路径

set diff_path to "/Applications/pp/dev/DiffMerge.app/Contents/MacOS/DiffMerge"
set cmd to diff_path & " '" & path1 & "' '" & path2 & "'"
do shell script cmd

您知道如何使用args运行activate，或者如何从appId获取完整路径吗？

在这里不能完全确定您的全部意图，但假设您希望在applescript中利用diffmerge的命令行功能，请尝试如下所示：

set appID to "com.sourcegear.DiffMerge"
set appIDO to application id "com.sourcegear.DiffMerge"
set diff_path to quoted form of POSIX path of (path to appIDO) & "Contents/MacOS/DiffMerge"
set path1 to quoted form of "/tmp/file1.txt"
set path2 to quoted form of "/tmp/file2.txt"
set cmd to diff_path & space & path1 & space & path2
do shell script cmd

它将运行以下shell命令：

"'/Applications/pp/dev/DiffMerge.app/Contents/MacOS/DiffMerge' '/tmp/file1.txt' '/tmp/file2.txt'"

quoted form代码将文本括在单引号中，这样shell就不会对其进行进一步的解释。对于您的特定示例，这可能不是问题，但如果路径或文件名中有空格，应该不会导致错误。space做的是显而易见的事情。如果你愿意，你可以把上面的代码压缩成更少的几行。

要了解更多关于applescript如何处理'do shell‘的信息，请查阅苹果技术笔记TN2065 (很容易找到)。我应该补充说，activate命令不是此过程的一部分。该命令将使活动应用程序发生差异合并(取决于…可能导致窗口打开)。

更新：

path to appID触发了应用程序的启动，我不知道有任何方法可以抑制这一点。

可以拼凑到应用程序的命令行界面工具的路径，但它不是通用的-特别是在/Applications中的嵌套文件夹。

set sName to "DiffMerge"
set cName to "DiffMerge"

set aPath to path to (applications folder) as text
set sFol to ":Contents:MacOS:"
--> ":Contents:MacOS:"

set gApp to aPath & sName & ".app"
--> "MacHD:Applications:DiffMerge.app"

set cTool to aPath & gApp & sFol & cName
--> "MacHD:Applications:DiffMerge.app:Contents:MacOS:DiffMerge"

set cmdPath to quoted form of POSIX path of cTool
--> "'/Applications/DiffMerge.app/Contents/MacOS/DiffMerge'"


set path1 to quoted form of "/tmp/file1.txt"
set path2 to quoted form of "/tmp/file2.txt"

cmdPath & space & path1 & space & path2
--> "'/Applications/MacHD/Applications/DiffMerge.app/Contents/MacOS/DiffMerge' '/tmp/file1.txt' '/tmp/file2.txt'"
