# richTextSource

Returns the syntax-highlighted source code of the receiver if the receiver has been compiled and its source code is available.

## Declaration

```swift
var richTextSource: NSAttributedString? { get }
```

## Discussion

Discussion Returns nil otherwise. It is possible for an instance of NSAppleScript that has been instantiated with init(contentsOf:error:) to be a script for which the source code is not available, but is nonetheless executable.
