macOS AppleScript: Return a value to the Terminal?

[RachitGupta]

Hi Guys,

I'm starting to learn AppleScript after moving from Windows.

How do I return a string back to the terminal after executing an AppleScript?

Thanks!

Use return:

return "hello world"

Hey,

I tried that, I saved it as an executable and then I went in terminal and typed "open test.app" and it opened and closed without outputting anything.

Am I supposed to include anything else in the program code other than that one line?

I think you want osascript instead. In Terminal type "man osascript" for more info.

AppleScript is more suited for working with applications, not running as a command-line tool. You might be better off using another language, such as Python or Ruby. What are you trying to do?

Edit: found this (new in Snow Leopard)

osascript now supports the log command; the output will be sent to stderr.

Are you wanting to use the string in a variable or just have it immediately print out?

Oh, I see.

What I'm trying to do is make an app (cross platform) that has to be able to tell what song you're listening to on iTunes. I don't know C, so I chose to go with Adobe Air because i'm a web developer and can basically write the adobe air app in javascript/html. Adobe Air on mac will call on an applescript via command line to find out what song is currently being played, because I don't see any other way to do it. When on Windows, it'll open a different program that works on Windows via command line.

The reason I chose AppleScript to work with Adobe Air is because finding what the name of the current track being played is very simple in AppleScript, and I couldn't find a simple example in C that I would be able to compile!

Yea, AppleScript is the right choice for what you want.

This may do what you need

osascript -e "tell application \"iTunes\" to return name of current track"

Thanks, I'm getting an error when I run this, though:

Rachit-Guptas-MacBookesktop silver$ osascript -e "tell application \"iTunes\" to return name of current track"

The last line, however, is the song that I'm listening to.
