Dumping ASTs

4 declarations

valueshowAstData :: Data a => BlankSrcSpan -> BlankEpAnnotations -> a -> SDoc

Show a GHC syntax tree. This parameterised because it is also used for comparing ASTs in ppr roundtripping tests, where the SrcSpan's are blanked out, to avoid comparing locations, only structure

valueshowAstDataFull :: Data a => a -> SDoc

Show the full AST as the compiler sees it.

datadata BlankSrcSpan

Should source spans be removed from output.
