描述

  1. Run MacDown: the default blank document opens.
  2. Choose File > Open to open another document.

EXPECTED: The new document opens, and the default blank document is still there. (Incidentally I think it would be a good enhancement to close the default blank document when opening another document, if the default blank document has no unsaved changes.)

ACTUAL: The opened document window appears, but a message box appears reporting a caught exception, and saying that you can click Continue to run in an inconsistent state, but woe betide you.

  1. Click Continue.

EXPECTED: Not sure. Hopefully I can keep working! ACTUAL: MacDown crashes out.

WORKAROUND: Close the default document before opening the document you want to edit, and only have one document window open at once.

研究方向
Focus on the document opening workflow in MacDown, likely using NSDocument. Investigate the exception when opening a second document while the default blank document is open. Check for any existing fixes or discussions in the issue comments (7 comments). Look at the repository's commit history for similar fixes. The crash may be due to improper handling of multiple windows or document state.
