git - POSIX 文件 "."作为别名导致 "CFURLGetFSRef was passed this URL which has no scheme"警告

Question

我正在使用 Araxis 提供的 applescripts，这样我就可以使用 Merge 来处理我的“git diff HEAD”命令。

但是，自升级到 Mountain Lion 后，每次运行命令时，我都会收到警告:

CFURLGetFSRef was passed this URL which has no scheme 
(the URL may not work with other CFURL routines): .

在脚本中，问题似乎是

set _file2 to (POSIX path of (POSIX file "." as alias)) & _file2

当我对路径进行硬编码而不是使用 "." 时，警告消失了。我已经尝试在 file:/// 之前添加，但是 POSIX path of 正在考虑将其中一个斜杠作为转义字符，因此路径变为 file:/Users/... 然后生成一个错误，因为有一个未知的模式(因为第二个斜杠被删除)。所以，我的问题是，获取当前位置的 POSIX 文件 的正确方法是什么(现在，在 Mountain Lion 中)？

添加完整脚本

#!/usr/bin/osascript
# This script is required to reorder the parameters sent by Git, so that they may be passed into the Merge Applescript API
on run args
  tell application "Araxis Merge"
    set _file1 to item 2 of args as text
    set _file2 to item 5 of args as text  

    if not _file1 starts with "/"
      set _file1 to (POSIX path of (POSIX file "." as alias)) & _file1
    end if

    if not _file2 starts with "/"
      set _file2 to (POSIX path of (POSIX file "." as alias)) & _file2
    end if


    set _document to compare {_file1, _file2}

    tell _document
      activate
    end tell
    repeat while exists _document
      delay 1
    end repeat
  end tell
end run

#!/usr/bin/osascript

on run args
  tell application "Araxis Merge"
    set _file1 to item 2 of args as text
    set _file2 to item 5 of args as text  

    if not _file1 starts with "/"
      set _file1 to (POSIX path of (POSIX file (do shell script "pwd") as alias)) & _file1
    end if

    if not _file2 starts with "/"
      set _file2 to (POSIX path of (POSIX file (do shell script "pwd") as alias)) & _file2
    end if

    set _document to compare {_file1, _file2}

    tell _document
      activate
    end tell
    repeat while exists _document
      delay 1
    end repeat
  end tell

osascript 每次显示警告 relative path is converted to an alias 10.8 日。

$ touch test.txt
$ osascript -e 'POSIX file "test.txt" as alias'
2012-12-19 09:43:49.300 osascript[16581:707] CFURLGetFSRef was passed this URL which has no scheme (the URL may not work with other CFURL routines): test.txt
alias HD:private:tmp:test.txt

这是另一种转换路径的方法:

osa() {
    osascript - "$PWD" "$@" <<'END'
on run argv
repeat with f in items 2 thru -1 of argv
if f does not start with "/" then set f to item 1 of argv & "/" & f
posix file f as alias
end
end
END
}

osa ~/Documents/ 1.txt

您也可以只重定向 stderr。

osa() {
    osascript - "$@" <<END 2> /dev/null
on run argv
POSIX file (item 1 of argv) as alias
end
END
}
osa test.txt
