wiki:Commentary/Abbreviations

Version 12 (modified by megacz, 4 years ago) (diff)

I FIGURED IT OUT!!!! Rdr is an abbreviation for "parser"! How obvious!

Certain abbreviations are used pervasively throughout the GHC source code. A few, like "Tc", are easy to figure out. Others, like "Occ", are more challenging (in case you were wondering, none of GHC's code is Occult, except perhaps in the Latin sense)

See also: A similar list on the GHC Users' wiki.

  • "Occ" means "Occurrence"
    • However, in the context of OccName, "occurrence" actually means "unqualified"
  • "Rn" means "Renamer"
  • "Rdr" means "Parser" (do not ask me why, I don't know)
  • "Tc" means "TypeCheck{ing,er}"
  • "Lcl" means "Local"
  • "Gbl" means "Global"
  • "Loc" means "Location", as in SrcLoc
  • "Hs" means "Haskell Syntax" (generally as opposed to Core -- for example, Expr vs HsExpr)
