# `GSWritingDirection.isLeftToRight`

*Instance Property*

Whether the right-to-left glyph-progression bit is clear.

## Declaration

```swift
var isLeftToRight: Bool { get }
```

## Discussion

This is also `true` for bidirectional and vertical values. Use [`GSWritingDirection.isHorizontal`](/Core/GlyphsCore/GSWritingDirection/isHorizontal) to distinguish horizontal text.
