Hi I want literate Haskell, but where the literate bit forming a document is actually HTML, not latex. Does anyone have any idea how to go about this? For a start, how do I persuade GHC to run the file: C:\Documents\Uni\tagsoup>runhaskell index.html Warning: ignoring unrecognised input `index.html' <interactive>:1:108: attempting to use module `Main' (Main.hs) which is not loaded And leading on to that, how Cabal might be used to compile the file. Secondly, what tricks can people think of for placing the code inside - I have come up with: <code>
foo = 1 </code>
And: <code> <!-- \begin{code} --> foo = 1 \end{code} </code> I can then hide the trailing \end{code} with a margin-bottm: -2em. Does anyone have any other ideas? Thanks Neil

You could replace the "unlit" executable in the GHC library directory with one which knows how to extract Haskell code from HTML. -- brandon s. allbery [solaris,freebsd,perl,pugs,haskell] allbery@kf8nh.com system administrator [openafs,heimdal,too many hats] allbery@ece.cmu.edu electrical and computer engineering, carnegie mellon university KF8NH
Hi Brandon,
You could replace the "unlit" executable in the GHC library directory with one which knows how to extract Haskell code from HTML.
I want a solution so that I can write the tagsoup manual in an way that can actually be run - I'd rather not force any additional dependence on a custom unlit command. However, adding HTML-style literate code to a future Haskell standard might not be a bad idea. Thanks Neil

I think HTML entities will cause problems with that, though. <pre> blocks *might* work to some extent, though. -- brandon s. allbery [solaris,freebsd,perl,pugs,haskell] allbery@kf8nh.com system administrator [openafs,heimdal,too many hats] allbery@ece.cmu.edu electrical and computer engineering, carnegie mellon university KF8NH

In the mean time you could prototype it as a pre-processor in Cabal if you write the unlit code. Duncan

The numeric-quest library was the first and only one that I have seen in this style. I could only get it working both in GHC and a browser by creating links. Say Module.lhs Module.html -> Module.lhs http://darcs.haskell.org/numeric-quest/

I haven't thought this through, but maybe you could hide the trailing bit by : -- <!-- \end{code} --> Richard.
Hello, You can compile a .html file with: ghc --make -x lhs index.html if you write the code like this: <code>
foo = 1
</code>
N.B. You need an empty line between <code> and the code and one between
the code and </code>.
The -x flag doesn't seem to work for runhaskell, when I try this, I get
the message:
<interactive>:1:112:
attempting to use module `Main' (Main.hs) which is not loaded
Regards,
Henk-Jan

Hi All, Thanks for the general help on literate HTML. It seems that using bird-tick style literate works better than \begin{code} style. I tried it with my document, but quickly gave up - mainly because I decided literateness did not fit with what I was doing.
You can compile a .html file with: ghc --make -x lhs index.html
You can also load it in GHCi with:
ghci -x lhs index.html
The -x flag doesn't seem to work for runhaskell
I couldn't get it working either, so have raised a feature request bug. Thanks for everyone's help, Neil

Which has been merged into #1232: http://hackage.haskell.org/trac/ghc/ticket/1967#comment:1 -- vvv
