# inputFieldSeparator

A string to use as the delimiter between items in the string passed to the action through standard input.

## Declaration

```swift
var inputFieldSeparator: String { get }
```

## Discussion

Discussion The Automator framework converts the output from the previous action (which is usually in the form of a list or array) into a single string in which the array elements are concatenated by the input field separator. By default, this separator is the newline character (\n). You can override this method to, for example, return a null character (\0) to provide null-terminated strings for xargs -0.
