wiki:Commentary/Abbreviations

Version 20 (modified by dwincort, 3 years ago) (diff)

--

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 "classified (i.e. as a type name, value name, etc) but not qualified and not yet resolved"
  • "Rn" means "Renamer"
  • "Rts" means "Run Time System"
  • "Rdr" means "Parser" (or reader)
  • "Ds" means "Desugarer"
  • "Ty" means "Type"
  • "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?)
  • "Hsc" means "deals with compiling a single module and no more"
