Handle link taps

[fishcharlie]

It would be great if there was a way to handle link taps within my own application as opposed to having swift-markdown-ui handle it for me.

This would allow for applications that set a custom browser to work, as well as in app browsers to work as well.

Hi @fishcharlie,

You can set a custom action to handle links in the openURL environment value.

Markdown {
  """
  Visit the [terms](https://www.example.com) and [conditions](https://apple.com).
  """
}
.environment(\.openURL, OpenURLAction { url in
  // Modify a state, execute an action, etc., based on 'url'
  return .handled
})

The example Demo application uses this technique in the Repository README section to scroll to the corresponding heading when the user taps an anchor link instead of opening it in Safari:

swift-markdown-ui/Examples/Demo/Demo/RepositoryReadmeView.swift

Lines 126 to 140 in 5f977ba

	func scrollToMarkdownHeadings(using scrollViewProxy: ScrollViewProxy) -> some View {
	self.environment(
	\.openURL,
	OpenURLAction { url in
	guard let fragment = url.fragment?.lowercased() else {
	return .systemAction
	}
	withAnimation {
	scrollViewProxy.scrollTo(fragment, anchor: .top)
	}
	return .handled
	}
	)
	}
	}
