I have the problem that I can't haddock literate modules (latex-style),

haddock -h -o docs Test.lhs Test.lhs:1:1: Parse error

the file begins with "\begin{code}".

Does anybody know what's up and what to do about it?

Haddock doesn't understand literate files on its own. The documentation describes how to get around this... er, well the documentation in CVS describes how to get around this, but the 0.6 docs on the web don't. Here's the relevant text: <section id="cpp"> <title>Using literate or pre-processed source</title> <para>Haddock only accepts plain, non-literate, Haskell source. This means that if you program in Literate Haskell, or you need to use the C pre-processor in your Haskell source, then you need to pre-process the files before feeding them to Haddock. This is easily accomplished using GHC; for example, suppose we have a Literate Haskell source file <filename>Foo.lhs</filename>, on which we also need to run the C pre-processor:</para> <screen> $ ghc -cpp -E -optP-P -D__HADDOCK__ Foo.lhs -o Foo.hs $ haddock -h Foo.hs ... </screen> <para>The <option>-E</option> option to GHC says "stop after pre-processing", the <option>-cpp</option> option turns on the C pre-processor, the <option>-optP-P</option> option tells the C pre-processor not to leave any extra dropping behind (see the description of the <option>-P</option> option in the gcc manual for details), and the <option>-D__HADDOCK__</option> option defines the symbol <literal>__HADDOCK__</literal> when pre-processing (this is sometimes handy if you need to any pre-processing conditionals in your source which depend on whether the source is going to be fed to Haddock).</para> </section> Cheers, Simon
