* API Annotations: Keep track of unicode for linear arrow notationwip/az/unicode-hsscaledAlan Zimmerman2020-10-201-0/+1
| | | | | | | | | | | The linear arrow can be parsed as `%1 ->` or a direct single token unicode equivalent. Make sure that this distinction is captured in the parsed AST by using IsUnicodeSyntax where it appears, and introduce a new API Annotation, AnnMult to represent its location when unicode is not used. Updated haddock submodule
* ApiAnnotations : preserve parens in GADTsAlan Zimmerman2020-10-091-0/+39
| | | | | | | | | A cleanup in 7f418acf61e accidentally discarded some parens in ConDeclGADT. Make sure these stay in the AST in a usable format. Also ensure the AnnLolly does not get lost in a GADT.
* Use ADTs for parser errors/warningsSylvain Henry2020-10-011-4/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Haskell and Cmm parsers/lexers now report errors and warnings using ADTs defined in GHC.Parser.Errors. They can be printed using functions in GHC.Parser.Errors.Ppr. Some of the errors provide hints with a separate ADT (e.g. to suggest to turn on some extension). For now, however, hints are not consistent across all messages. For example some errors contain the hints in the main message. I didn't want to change any message with this patch. I expect these changes to be discussed and implemented later. Surprisingly, this patch enhances performance.

* New linear types syntax: a %p -> b (#18459)Vladislav Zavialov2020-09-291-3/+1
| | | | | | Implements GHC Proposal #356 Updates the haddock submodule.
* ApiAnnotations; tweaks for ghc-exactprint updateAlan Zimmerman2020-08-071-2/+3
| | | | | | Remove unused ApiAnns, add one for linear arrow. Include API Annotations for trailing comma in export list.
* Clean up haddock hyperlinks of GHC.* (part1)Takenobu Tani2020-06-251-6/+6
| | | | | | | | | | | | | | | | | | | This updates haddock comments only. This patch focuses to update for hyperlinks in GHC API's haddock comments, because broken links especially discourage newcomers. This includes the following hierarchies: - GHC.Hs.* - GHC.Core.* - GHC.Stg.* - GHC.Cmm.* - GHC.Types.* - GHC.Data.* - GHC.Builtin.* - GHC.Parser.* - GHC.Driver.* - GHC top
