Why do you want to rewrite the indenter in Haskell? If haskell-mode has any external dependencies such as that one, it will most likely never make it into Emacs.

In no particular order: - For any given line, there are typically several possible indentations. We can cycle between these, but it's better to minimize them. - I want the parser to be as accurate as possible. This essentially means reimplementing haskell-src-exts, unless I *use* haskell-src-exts. - In many cases, the legal indentations depend on the types of the expressions involved. This can be figured out, but requires part of the code to be running in GHC *anyway*. - Elisp is a lousy language compared to haskell, and I don't really care about getting haskell-mode into the emacs distribution. It makes more sense to bundle it with GHC, if it has to be bundled. - Most of haskell-mode will work without this helper program, including the three other indentation modes. -- Svein Ove Aas
