brittany v0.12.0.0 Release Notes

Release Date: 2019-06-01 // almost 5 years ago
    • 👌 Support for ghc-8.6 (basic support, not necessarily all new syntactic extensions)
    • 👌 Support -XExplicitNamespaces and -XPatternSynonyms
    • 👍 Allow a --dry-run sort of operation via flag "-c/--check-mode" (thanks to Doug Beardsley @mightybyte)
    • 👍 Include file name in errors about unsupported syntax nodes (thanks to @5outh)
    • Partially implement layouting class instances: Layouts children, but falls back on ghc-exactprint for the instance head (thanks to Rupert Horlick @ruhatch)
    • Implement layouting for type synonyms (thanks to Rupert Horlick @ruhatch)
    • 👌 Support -XMagicHash, -XUnboxedTuples (thanks to Sergey Vinokurov @sergv)
    • 👌 Support -XQuasiQuotes (no formatting applied to the splices; they are simply retained without causing the dreaded "Unknown construct: HsSpliceE{}")
      • lconfig_allowHangingQuasiQuotes controls whether multi-line QuasiQuotes are allowed to start at the end of the current line, or whether they are always placed in new lines.

      • Stop removing empty lines before where keyword in a couple of cases
      • Fix functions with mixing prefix/infix style causing error (#234)
    • 🔄 Changes to layout:
      • Align usage of spaces for record update vs record construction (#126)
      • More indentation to import-hiding-paragraph (follow-up to #150 fix)
      • Record construction and update now are layouted in the same way (thanks to Evan Rutledge Borden @eborden)

    • 🏗 Various build-instructions and editor integrations
