By the way, if someone on this list has got too much time, he could write something that would fulfill the goals of literate programming -- à la web and cweb. Knuth was able to make books with his source code. I believe that lhs2tex is great for classes about haskell or fp, but I never found it satisfying for programs with several modules, for instance.

They were under "/Users/username/.cabal/share/lhs2tex-1.15" and this path was not in the search path of lhs2TeX. I'm using Snow Leoprad. This might be a bug I guess?

Anyway, problem solved for me.

Best,

I am trying to get lhs2TeX to work. I installed the package using cabal, and now I try to run it on a very simple *.lhs file.

But it blames me and says user error, cannot find lhs2TeX.fmt:

lhs2TeX: user error (File `lhs2TeX.fmt' not found in search path:

And, when I check the search path, there really is no lhs2TeX.fmt file. Should I download it separately or something like that?

PS: Thanks for the great package to the authors!

Best, Ozgur Akgun

I think the main difference between cweb and literate haskell is that the former allows documentation _anywhere_, whereas with literate haskell you can't suddenly cut out of a code block to have a discussion on what the next line means (instead you need to have an explicit comment). Unless GHC[i] starts stripping out all non-code from literate haskell files and joining all the code blocks together, I'm not sure if this situation can be remedied.

Not quite; the lhs2tex documentation says you need to put those .fmt, .sty, etc. files in a texmf directory. -- Ivan Lazar Miljenovic Ivan.Miljenovic@gmail.com IvanMiljenovic.wordpress.com

Oh I assumed, cabal-installing lhs2tex would put those files into some place so that it can find them later :)

Where exactly in the documentation does it say I have to manually put them in my texmf dir?

Page 5 of http://people.cs.uu.nl/andres/lhs2tex/Guide2-1.15.pdf However, it appears I was mistaken regarding lhs2tex.fmt; instead it appears that the executable doesn't know where the .fmt file is to be found. You'll have to wait until Andres responds for clarification on this :s -- Ivan Lazar Miljenovic Ivan.Miljenovic@gmail.com IvanMiljenovic.wordpress.com
