dialog - 在后台显示和更新 applescript 输出

Question

我有一个简短而有趣的程序，可以在 applescript 中输出我的内部和外部 ip。

这里是 Applescript 代码:

set inIP to IPv4 address of (get system info)
set exIP to (do shell script "curl ipecho.net/plain")
display dialog "Internal: " & inIP & "
External: " & exIP

我希望它在后台不断更新，最好不要像现在那样在显示对话框功能中更新。

我不希望 显示对话框 不断弹出，因此我正在寻找例如，在 菜单栏 中显示 IP。

我不知道这是否可能与 Applescript 相关

Answer 1

从 10.10(我认为)开始，您可以直接在脚本编辑器中使用 ApplescriptOBJC 创建真正的应用程序。

我之前没有真正尝试过，但是一旦你开始，它比我预期的要容易。

将此代码粘贴到新的脚本编辑器 Applescript 文档中。

使用另存为...菜单选项将其保存为保持打开的应用程序。

然后将应用程序作为普通应用程序运行。

使用 OP 的原始 applescript 代码

use AppleScript version "2.4"
use scripting additions
use framework "Foundation"
use framework "AppKit"

property StatusItem : missing value

-- check we are running in foreground - YOU MUST RUN AS APPLICATION. to be thread safe and not crash
if not (current application's NSThread's isMainThread()) as boolean then
    display alert "This script must be run from the main thread." buttons {"Cancel"} as critical
    error number -128
end if

-- create an NSStatusBar
on makeStatusBar()
    set bar to current application's NSStatusBar's systemStatusBar

    set StatusItem to bar's statusItemWithLength:-1.0

    -- set up the initial NSStatusBars title
    StatusItem's setTitle:"IP"
end makeStatusBar

-- update statusBar
on displayIP(theDisplay)
    StatusItem's setTitle:theDisplay
end displayIP

--repeat run  update code
on idle

    --get the IPs
    set inIP to IPv4 address of (get system info)
    set exIP to (do shell script "curl ipecho.net/plain")

    set theDisplay to "Internal: " & inIP & " External: " & exIP

    my displayIP(theDisplay)
    return 30 -- run every 30 seconds

end idle
-- call to create initial NSStatusBar
my makeStatusBar()

应用设置为每 30 秒运行一次。它将使用您的 ips 更新菜单栏中的状态栏菜单。

我没有输入任何错误检查并将其留给您。

还请记住，如果您想在脚本编辑器中运行代码，请确保使用“运行应用程序”。

更新:1我已将内部 IP 地址代码更改为使用 NShost，它比“get system info”

更快且可能更可靠

更新:2

更新外部代码以使用 NSURL 请求而不是原始 Curl 执行 shell 脚本命令。

如果由于没有网络连接而导致获取外部 IP 地址失败...等，则可以更轻松地检查错误。

Curl 将返回有关失败原因的完整信息日志，恕我直言，这很痛苦。

更新的 AppleScript 代码

use AppleScript version "2.4"
use scripting additions
use framework "Foundation"
use framework "AppKit"

property StatusItem : missing value

-- check we are running in foreground - YOU MUST RUN AS APPLICATION. to be thread safe and not crash
if not (current application's NSThread's isMainThread()) as boolean then
    display alert "This script must be run from the main thread." buttons {"Cancel"} as critical
    error number -128
end if

-- create an NSStatusBar
on makeStatusBar()
    set bar to current application's NSStatusBar's systemStatusBar

    set StatusItem to bar's statusItemWithLength:-1.0

    -- set up the initial NSStatusBars title
    StatusItem's setTitle:"IP"
end makeStatusBar

-- update statusBar
on displayIP(theDisplay)
    StatusItem's setTitle:theDisplay
end displayIP

--repeat run  update code
on idle

    --get the IPs

    set stringAddress to ""
    --use NSHost to get the Internal IP address 
    set inIPAddresses to current application's NSHost's currentHost's addresses

    --work through each item to find the IP
    repeat with i from 1 to number of items in inIPAddresses
        set anAddress to (current application's NSString's stringWithString:(item i of inIPAddresses))
        set ipCheck to (anAddress's componentsSeparatedByString:".")
        set the Counter to (count of ipCheck)

        if (anAddress as string) does not start with "127" then
            if Counter is equal to 4 then
                set stringAddress to anAddress
                -- found a match lets exit the repeat
                exit repeat
            end if
        else
            set stringAddress to "Not available"
        end if
    end repeat

    -- Get extenal IP

    set anError to missing value
    set iPURL to (current application's NSURL's URLWithString:"http://ipecho.net/plain")

    set NSUTF8StringEncoding to 4
    set exIP to (current application's NSString's stringWithContentsOfURL:iPURL encoding:NSUTF8StringEncoding |error|:anError) as string
    if exIP contains missing value then
        set exIP to "Not available"
    end if



    set theDisplay to "Intl: " & stringAddress & " Extnl: " & exIP

    --call to update statusBar
    my displayIP(theDisplay)

    return 30 -- run every 30 seconds

end idle
-- call to create initial NSStatusBar
my makeStatusBar()

更新 3

这个将按照 OP 在评论中的要求进行。

它现在有一个下拉菜单，其中包含外部或内部两个选项。

选择一个或另一个菜单项将更改状态栏以显示所选 IP。

最后一个很快就拼凑起来了，所以不太漂亮。 :-)

(UPDATE 4它还会在退出应用程序和重新启动时保留选择。)
