Alan Zimmerman pushed to branch wip/az/exactprint-annotation-rationalisation at Glasgow Haskell Compiler / GHC Commits: f1dffcfe by Alan Zimmerman at 2026-08-11T20:33:59+01:00 EPA: Remove ListBanana / ListParens from AnnListBrackets - - - - - c753f41b by Alan Zimmerman at 2026-08-11T23:09:33+01:00 EPA: Tidy up mkHsDoPv, take AnnList directly And some extra stuff by accident. The main goal is to slim down AnnListBrackets to just have braces or none. This makes it clear that it serves only for lists which may have layout, and opens the route to use EpLayout instead of AnnListBrackets - - - - - 2fed12ec by Alan Zimmerman at 2026-08-12T18:50:45+01:00 EPA: Add specific layout field to AnnList - - - - - affb39d4 by Alan Zimmerman at 2026-08-12T21:06:15+01:00 EPA: Use EpaLocation in EpVirtualBraces reword: EPA Use vocurly as basis for AnnListLayout For the existing cases that populate AnnList. This also shows up AnnList usages that can never capture layout. - - - - - 23c18c09 by Alan Zimmerman at 2026-08-12T21:29:47+01:00 EPA Use vocurly as basis for AnnListLayout For the existing cases that populate AnnList.

It lays the groundwork for using them for exact print annotations - - - - - 6a641163 by Alan Zimmerman at 2026-08-12T21:29:47+01:00 WIP annclassdecl - - - - - 09e02068 by Alan Zimmerman at 2026-08-12T21:29:47+01:00 EPA: Update AnnClsInstDecl to contain AnnList It was already separately tracking the '{', '}' and leading ';' values. This aligns it with layout-introducing parser productions ('vocurly'), so the layout processing can be handled uniformly - - - - - cab6b18a by Alan Zimmerman at 2026-08-12T23:35:32+01:00 EPA: First pass implementation of HsList, for ClassDecls Just as a straight list replacement to start with, no payload. This shows the scope and invasiveness of the initial change - - - - - 3eb49aa3 by Alan Zimmerman at 2026-08-12T23:35:32+01:00 EPA: HsList attempt WIP - - - - - 9813d8dc by Alan Zimmerman at 2026-08-12T23:35:32+01:00 Enable ppr test for Haddock1.
