Hi,
Is there a way to determine the order in which thunks are created and expanded/evaluated in Haskell (GHC)? I'm looking mainly at some existing interface but if there is only something in the GHC source it will suffice.
You'll want to look at STG (spineless tagless G-Machine). See here and the linked paper: http://www.haskell.org/haskellwiki/Ministg I don't know of any way to examine this for a running program. You can get GHC to spit out core and STG using -ddump-core and -ddump-stg flags: http://www.haskell.org/ghc/docs/6.12.2/html/users_guide/options-debugging.ht... I hope that helps, Jason
