Hello, I am attempting some genetic programming in Haskell.
Rather than defining my own data type for programs and writing my own interpreter, I want to use the template haskell expression data types and evaluate them with the rts's byte code interpreter. This gives me a nice fast interpreter that provides the statistics that I want. I could pretty print the template haskell and then execute the result string using the GHC module or hs-plugins, but I would like to save the pretty printing and parsing as normally the program generation time is important by GP. I have being looking at module TcSplice. I see that I need to run the TH expression through function convertToHsExpr, but after that I am stuck. This produces LHsExpr RdrName and I need to get CoreSyn.CoreExpr. What functions to use? dsLExpr :: LHsExpr Id -> DsM CoreSyn.CoreExpr seems one important step, but I haven't figured out how to get from LHtsExpr RdrName to LHsExpr Id. It would be nice to have standard GHC functionality to have the ability to compile and evaluate template haskell at runtime using the GHC library. Rene. _______________________________________________ Glasgow-haskell-users mailing list [email protected] http://www.haskell.org/mailman/listinfo/glasgow-haskell-users
