描述

This complicates parsing the output of GHC, and breaks the contract that is implied by -ddump-json. See #1955 for an example of when this comes up.

Two things I've found are: the header (see also #1956 for another issue related to this), and certain WARNING:s that are printed when the plugin finds false in a specification. Unsure if this second one is just a debug message that was forgotten to be switched off or something.

研究方向
Investigate the Liquid Haskell plugin code that prints messages when ddump json is enabled. Focus on the header output and any WARNING messages related to 'false' in specifications. Check the referenced issues #1955 and #1956 for context. Determine which parts of the code output non JSON and ensure they adhere to JSON format.
