I've been looking at the docs for Haddock at http://haskell.org/haddock/haddock-html-0.7/index.html but I can't seem to find any option to recursively traverse a directory generating hyperlinked docs for all modules anywhere in the directory or any sub directory etc.

Is there a simple undocumented flag I'm missing?

Haddock doesn't do this on its own, but Cabal can do it (./setup haddock). You do have to specify all the modules in the .cabal file though, so it's not really "traversing a directory".

Thanks for this suggestion. I've also got things to work quite well by using the following makefile on a Windows command shell (using a Win32 port of gnu make and based on a helpful example makefile received offlist): # Makefile for Haddock docs GHCFLAGS = -fglasgow-exts -fffi API_FILES := $(wildcard *.hs) # preprocess for Haddock %.haddock:%.hs ghc $(GHCFLAGS) -cpp -E -optP-P -D__HADDOCK__ $^ -o docs/$@ # generate docs docs: $(patsubst %.hs,%.haddock,$(API_FILES)) haddock -o docs -h $(addprefix docs/, $^) This works as long as all the subdirectories containing modules are explicitly listed in API_FILES, and the whole directory tree (including the docs directory) is manually created (for Windows, since Windows doesn't automatically create directories that don't exist when it tries to open a file for writing when the filename contains a path) - not a big problem since the directory tree only needs to be created once.
