Description

Adds jump to definition, including a new key command (control-command-J) to initiate a jump, and an interaction (command + mouse click). The destination(s) for a jump is provided via a new object protocol, provided via the SwiftUI API. The popover presented when multiple links are present reuses the completion window, with a slight modification so that it appears as a popover with an arrow rather than a floating window.

Detailed changes:

• Numerous fixes and improvements to the SuggestionController and SuggestionViewController, making them work when presented as a popover, as well as some resizing bugs.
• New CodeSuggestionPreviewView. Displays preview information for a code suggestion, including a syntax-highlighted source preview, documentation, and a path component.
  • This only appears when one of the three potential information is available, otherwise it is hidden.
  • This view is a visual effect view, so it will inherit the style of the suggestion controller from the user's theme with a slight tint.
• New JumpToDefinitionModel manages the mouse interaction, as well as providing the layer between the jump delegate and the code suggestion window.
• New JumpToDefinitionDelegate protocol defines how the editor can use the delegate object to query links and open them once selected.
