From a5199600c39d25d7b71dcb2328000c1c49ad95a2 Mon Sep 17 00:00:00 2001 From: Alec Theriault Date: Wed, 6 Feb 2019 01:01:41 -0800 Subject: Better identifier parsing * '(<|>)' and '`elem`' now get parsed and rendered properly as links * 'DbModule'/'DbUnitId' now properly get split apart into two links * tuple names now get parsed properly * some more small niceties... The identifier parsing code is more precise and more efficient (although to be fair: it is also longer and in its own module). On the rendering side, we need to pipe through information about backticks/parens/neither all the way through from renaming to the backends. In terms of impact: a total of 35 modules in the entirety of the bootlib + ghc lib docs change. The only "regression" is things like '\0'. These should be changed to @\\0@ (the path by which this previously worked seems accidental). --- haddock-api/src/Haddock/Parser.hs | 19 ++++++++++++------- 1 file changed, 12 insertions(+), 7 deletions(-) (limited to 'haddock-api/src/Haddock/Parser.hs') diff --git a/haddock-api/src/Haddock/Parser.hs b/haddock-api/src/Haddock/Parser.hs index 8b7dda7c..6d5dc103 100644 --- a/haddock-api/src/Haddock/Parser.hs +++ b/haddock-api/src/Haddock/Parser.hs @@ -15,27 +15,32 @@ module Haddock.Parser ( parseParas import qualified Documentation.Haddock.Parser as P import Documentation.Haddock.Types -import Haddock.Types (NsRdrName(..)) +import Haddock.Types import DynFlags ( DynFlags ) import FastString ( fsLit ) import Lexer ( mkPState, unP, ParseResult(POk) ) import Parser ( parseIdentifier ) -import RdrName ( RdrName ) import SrcLoc ( mkRealSrcLoc, GenLocated(..) ) import StringBuffer ( stringToStringBuffer ) -parseParas :: DynFlags -> Maybe Package -> String -> MetaDoc mod NsRdrName + +parseParas :: DynFlags -> Maybe Package -> String -> MetaDoc mod (Wrap NsRdrName) parseParas d p = overDoc (P.overIdentifier (parseIdent d)) .
