# startOfLine

An anchor that matches at the start of a line, including the start of
the input string.

```
static var startOfLine: Anchor { get }
```

## Discussion

This anchor is equivalent to `^` in regex syntax when the `m` option
has been enabled or `anchorsMatchLineEndings(true)` has been called.

For example, the following regexes are all equivalent:

- `Regex { Anchor.startOfLine }`
- `/(?m)^/` or `/(?m:^)/`
- `/^/.anchorsMatchLineEndings(true)`
