http://hackage.haskell.org/cgi-bin/hackage-scripts/package/htags

htags is a tag file generator to enable extra functionality in editors like vim. It expands upon hasktags by using a full Haskell 98 parser and options for recursion.

Hi, I've just tried to install it and the build fails here (GHC 6.8.3) $ cabal update $ cabal install htags ──(Mon,Nov03)─┘ Resolving dependencies... Downloading htags-1.0... Configuring htags-1.0... Preprocessing executables for htags-1.0... Building htags-1.0... src/htags.hs:8:7: Could not find module `GenTags': Use -v to see a list of the files searched for. cabal: Error: some packages failed to install: htags-1.0 failed during the building phase. The exception was: exit: ExitFailure 1 Best regards, -- Nicolas Pouillard aka Ertai

htags is a tag file generator to enable extra functionality in editors like vim. It expands upon hasktags by using a full Haskell 98 parser and options for recursion. Maybe you want to take some ideas from my enhanced hasktags version: http://mawercer.de/~nix/hasktags.hs

It has some features such as indexing only the first of those three matches (if they are found within 5 lines).. foo :: MyType -> IO () foo (Bar _) = foo (Cee _) = It's still not perfect. How do you handle extensions and cpp stuff? I mean will your program still parse #ifdef foo = #else foo = #endif ? No it doesn't. I've tried it. It doesn't handle .lhs files as well. Maybe it would be nice to have one hasktag program providing different strategies on hackage which could by synchronized with the one distributed with ghc? For vim you can also add tag classes (eg telling vim wether a found token is a (f)unction or a (c)lass ..) See the output of my enhanced version to generate some examples. Apart from .lhs and #ifdefs htags seems to work fine. Marc
