Yhc.Core format changes
by Neil Mitchell 30 Dec '06

30 Dec '06

Hi all, especially Dimitry, I've had to change the Yhc.Core format, sadly, so all Yhc.Core users will need to: 1) Pull a fresh copy 2) Clear their inst/lib/*.yca files 3) Rebuild yhc The change is minor, but important. This introduces a new form for the Core language, Lambda expressions. They are never used in the generated code by Yhc, and most transformations can successfully ignore them, but certain things require them, and when they do, there is pretty much no way around it. The extra constructor added is: CoreLam [String] CoreExpr Which has identical meaning to the Haskell construct: \arg1 arg2 -> expression Sorry for doing this, I really hope to never break the Core format again. Thanks Neil

Adding base libraries to yhc
by Christopher Lane Hinson 29 Dec '06

29 Dec '06

I posted on the bug tracker earlier about doing this and now I am actually attempting it. I went to darcs.haskell.org/packages/ and decided arbitrarily to start with Data.Map, which I copied into the packages/ directory in yhc. When I compile it complains about #if preprocessor statements, which enclose GHC specific code and could be commented out but also there is an #include and what looks like a macro that might actually be important. As I understand it the preprocessor is turned off in yhc (thus the error). As far as I can tell nothing else in packages/ uses preprocessor directives. Possibilities: 1) I should enable -cpp specifically for this file or globally for all of yhc, or just for packages/. (I'm not entirely sure how to get scons to do this but I need to take time and read the scons docs.) 2) I should remove and work around the preprocessor directives. If I start making changes how does yhc keep in sync with any changes that are made to the base packages upstream? 3) It doesn't matter. I should do whatever makes me happy. Please advise. Thanks. --Lane (Submitting this a second time because I snagged the moderation filter the first time.)
