貢獻指南
研究方向
The error originates in the pigments package, specifically in color-buffer-element.coffee and pigments.coffee. Start by examining the stack trace: the error occurs when accessing 'id' of undefined in a loop over extraRenderedScreenLines. Look at the colorMarkerForMouseEvent and shouldDisplayContextMenu functions. The issue likely involves a missing or undefined marker object when the context menu is triggered. Check the relevant CoffeeScript files in the lib directory to understand the data flow and identify where the undefined value is passed.
