Fellow haskellers:

Haskell-mode 2.6 has been released.

Make that 2.6.1. Naturally, I broke something, but I think I'm about out of things to break now.

As it happens, the haskell-indentation mode (the new one) doesn't like hierarchical modules names. Something like:

 module Foo.Bar (\n

will begin at the beginning of the line, complaining about there being an operator (the '.').

Though you may not have broken it. :) I can't recall if that happened previously or not.

What seems to be going on is that haskell-indentation simply isn't prepared to deal with hierarchical module names at all, or qualified imports. The latter works because it interprets "Foo.bar" as actually using the operator (.), which it considers to be valid syntax. Operators are not valid in module statements, however. I'm going to try teaching it. Hopefully I won't break anything in the process. -- Svein Ove Aas

I also thought of some font-lock symbols you could consider adding to haskell-font-lock.el: ;; Nice bottom symbol (cons "undefined" (decode-char 'ucs #X22A5)) ;; Small case pi symbol (cons "pi" (decode-char 'ucs #X3C0)) ;; This one is less serious (cons "unsafePerformIO" (decode-char 'ucs #X2620)) I don't know if the predicate in the list of font-lock symbols can express this condition, but it would be nice to be able to replace 'a' and 'b' in types with lowercase alpha (U003B1) and beta (U003B1) symbols. But only in the context of a type. Regards, Roel

Thanks for the update. I am using it now and am very happy with it! No more tabtabtabtabtab to properly indent something. I did notice a bug in the declaration scanning part. Blocks of haddock comments are parsed as code. Code like this: {-| bla bla bla -} will be parsed as a variable "bla". If you remove the pipe symbol "|" the comment is skipped. I though it would be an easy fix in the declaration scanner but my elisp-fu is too weak :-( This bug makes the nice imenu almost useless in well documented code. Otherwise I am a very happy user!
