.bootstrap(raise_on_fail: false) ⇒ Extension

Loads the code for the extension that the user is currently working inside. The ‘hippo` command uses this to detect what actions should be taken.

Will silently swallow any exceptions that are raised when the file is required and return nil

Returns:

  • (Extension) —

    extension that was loaded, nil if none was found
