AppleScript-Skype接口

| 我对AppleScript非常陌生。我发现此脚本可与GeekTool Geeklet一起使用,以显示在线Skype用户。当我运行AppleScript时,出现错误“ \ skype_id \”未定义。我找不到未定义的位置/原因。显然,该脚本在过去也可以使用。 这是错误: 错误“未定义变量skype_id。”来自“ skype_id \”的数字-2753 这是脚本:
on remvix(ix, ls)
if ls is {} then
    return {}
else if ix is 1 then
    return rest of ls
else
    return {item 1 of ls} & remvix(ix - 1, rest of ls)
end if
end remvix

on tail(astring, k)
return do shell script \"echo \'\" & astring & \"\' | awk \'{{i = \" & k & \"; while ( i <= NF-1 ) {printf $i \\\" \\\"; i++}; printf $i}}\'\"
end tail

property onlinegroup : 0

on getgroup()
tell application \"Skype\"
    if my checkgroup(onlinegroup) is true then
        return onlinegroup
    else
        set hardwired to send command \"search groups hardwired\" script name \"online users\"
        set hardwired to my tail(hardwired, 2)
        set hardwired to text items of hardwired
        repeat with i in hardwired
            if my checkgroup(i) is true then
                return i
            end if
        end repeat
    end if
end tell
end getgroup

on checkgroup(group_id)
tell application \"Skype\"
    set grouptype to send command \"get group \" & group_id & \" type\" script name \"online users\"
    set grouptype to my tail(grouptype, 4)
    if grouptype is \"ONLINE_FRIENDS\" then
        return true
    else
        return false
    end if
end tell
end checkgroup

property dropped : 0
set text item delimiters to \", \"
set onlineusers to {}
tell application \"System Events\"
set powerCheck to ((application processes whose (name is equal to \"Skype\")) count)

if powerCheck = 0 then
    set end of onlineusers to \" Skype not running\"
else
    tell application \"Skype\"
        set onlinegroup to my getgroup()
        set skype_id to send command \"get group \" & onlinegroup & \" users\"    script name \"online users\"
        set skype_id to my tail(skype_id, 4)
        set skype_id to text items of skype_id
        repeat with j from 1 to count skype_id
            if item j of skype_id is \"echo123\" then
                set skype_id_new to my remvix(j, skype_id)
                set dropped to 1
            end if
        end repeat
        if dropped is 1 then
            set skype_id to skype_id_new
        end if
        repeat with i in skype_id
            set aUser to send command \"get user \" & i & \" fullname\" script name \"online users\"
            set aUser to my tail(aUser, 4)
            if aUser is \"\" then set aUser to i
            set amoodtext to send command \"get user \" & i & \" mood_text\" script name \"online users\"
            set amoodtext to my tail(amoodtext, 4)
            if amoodtext is \"\" then
                set end of onlineusers to aUser
            else
                set end of onlineusers to aUser & \" (\" & amoodtext & \")\"
            end if
        end repeat

        if (count skype_id) > 0 then
            set item 1 of onlineusers to \" \" & item 1 of onlineusers
        else
            set beginning of onlineusers to \" No Contacts Online\"
        end if
        return onlineusers
    end tell
end if
end tell
在此先感谢您的帮助。

\'my tail \'是脚本自己的函数/处理程序,仅是awk(shell)脚本的包装。由于某种原因,该函数无法返回任何内容,并且我注意到它不包含任何错误检查。开始调试\'on tail \'块将很有用。例如,参数astring和k是否有意义?此错误处理代码可能会插入尾部处理程序的开头:
if ((class of astring) is not string) or ((class of k) is not integer) then
display dialog \"Screwy parameter sent to tail\" buttons {\"Rats\"} default button 1
error number -128 -- abort script entirely 
end if
如果找不到错误,则可能是awk行为异常,这似乎不太可能,但我想仍然可能。 只是一般的观察。我知道appleScript应该是一种友好,易用的语言(尽管不是),并且您可能是从其他人那里获得了此脚本,但是出于调试目的,您通过多次重新定义skype_id变量来寻求麻烦。 。 (这就是查克做出回应的原因)。
