I’m using Aeson to parse a JSON file in Haskell, and I’m letting Aeson auto-generate the parser by calling deriveJSON. Is there any way to view the code that Aeson generates? I tried calling deriveJSON at the command line, but the result from that function doesn’t derive Show, so it won’t print. Anyone know how to do this?
You can pass
-ddump-splicesto the compiler when compiling your code, which will output the generated parser code to the terminal. See this question that I asked a while ago for more information.
