# init(selectedText:contextBefore:contextAfter:markedText:selectedRangeInMarkedText:)

Initializes a document with plain text strings that represent the selection and its surrounding context.

## Declaration

```swift
init(selectedText: String?, contextBefore: String?, contextAfter: String?, markedText: String?, selectedRangeInMarkedText: NSRange)
```

## Parameters

- `selectedText`: The currently selected text, or nil for a caret selection. Pass an empty string, not nil, when the selection consists of nontext — in that case, a single call to delete backward doesn’t remove content from the contextBefore parameter. This value can be empty if the selection falls outside the context’s area, even if selected text exists elsewhere in the document.
- `contextBefore`: A suffix of the text that precedes the selection, or nil if the selection is at the beginning of the document. This string needs to correspond to a range that contains no nontext content. If the string contains a number of backward-deletion repetitions, that same number of delete-backward calls needs to remove the corresponding text from the document. The string needs to begin on a word boundary, or outside of a word entirely.
- `contextAfter`: A prefix of the text that follows the selection, or nil if the selection is at the end of the document. This string needs to correspond to a range that contains no nontext content. The string needs to end on a word boundary, or outside of a word entirely.
- `markedText`: The current marked text, or nil if no marked text exists. This value can be empty if the marked text falls outside the context’s area, even if marked text exists elsewhere in the document.
- `selectedRangeInMarkedText`: The range of the current selection relative to the marked text range. Pass (NSNotFound, 0) to indicate no marked text.
