| | | | | | | | | | | | | | | | | | | | | | | | | This commit replaces the old yacc parser with a Happy-generated one. Notes: - The generated .hs file is *big*. Best to use a recent version of Happy, and even better to add the -c flag to use unsafeCoerce# with ghc (versions 4.02+ please). - The lexer has grown all sorts of unsightly growths and should be put down as soon as possible. - Parse errors may result in strange diagnostics. I'm looking into this. - HsSyn now contains a few extra constructors due to the way patterns are parsed as expressions in the parser. - The layout rule is implemented according to the Haskell report. I found a couple of places in the libraries where we previously weren't adhering to this - in particular the rule about "nested contexts must be more indented than outer contexts". The rule is necessary to disambiguate in the presence of empty declaration lists.

| | | | | | | | | | | Be a little bit more user-friendly when encountering record puns, which is no longer supported by Haskell. Instead of a Plain Old Parse Error, print out foo.hs:11:11: Haskell 98 does not support 'punning' on records .... Hopefully that should give the user a big enough hint at what's going wrong..

| | | | | | | | | | | | | | | | | | | | | Another big commit from Simon. Actually, the last one didn't all go into the main trunk; because of a CVS glitch it ended up in the wrong branch. So this commit includes: * Scoped type variables * Warnings for unused variables should work now (they didn't before) * Simplifier improvements: - Much better treatment of strict arguments - Better treatment of bottoming Ids - No need for w/w split for fns that are merely strict - Fewer iterations needed, I hope * Less gratuitous renaming in interface files and abs C * OccName is a separate module, and is an abstract data type I think the whole Prelude and Exts libraries compile correctly. Something isn't quite right about typechecking existentials though.

| | | | | | | | | | | | | | | | | | | The Great Multi-Parameter Type Classes Merge. Notes from Simon (abridged): * Multi-parameter type classes are fully implemented. * Error messages from the type checker should be noticeably improved * Warnings for unused bindings (-fwarn-unused-names) * many other minor bug fixes. Internally there are the following changes * Removal of Haskell 1.2 compatibility. * Dramatic clean-up of the PprStyle stuff. * The type Type has been substantially changed. * The dictionary for each class is represented by a new data type for that purpose, rather than by a tuple.
