Re: [Haskell-cafe] lhs2TeX: automatic line wrap within code blocks?

Dominique, thank you very much for your reply! Yes, that would work for the code-blocks, but I'd still prefer automatic line wrapping like in this example: http://www.bollchen.de/blog/2011/04/good-looking-line-breaks-with-the-listin... Also this does not solve the case of multi line results in eval-statements. But still, thanks again - and as my deadline draws nearer (this is homework in a security lecture) I may use your solution and also decrypt the text first and then copy the decrypted text into the source file (to get rid of the eval-statement).

David,

The easiest solution is probably to use multi-line string literals and line-wrap manually:

\begin{code} cyphertext = "rlkmlj, zlnift ekblvke pqc elvm if pzlp gblrk, akrlomk zk zle \  lfpiriglpke pzlp, if pzk flpojlb rcojmk cs knkfpm, morz qcobe ak pzk rcfeorp \  cs nkjriftkpcjiu, bklnkm pzk ljdv ofekj gjkpkfmk cs jlimift jkrjoipm lfe \  rlnlbjv" \end{code}

Hello,

I am currently using lhs2TeX for the first time and have encountered a problem which I am unable to solve myself: Some code lines are too long to fit into a single line of the output (PDF) file and thus go off the right edge of the page.

Consider the following example:

-------------------------------------

\documentclass{article} \usepackage[utf8]{inputenc}

%include polycode.fmt %options ghci \begin{document}

Our encrypted message:

\begin{code} cyphertext = "rlkmlj, zlnift ekblvke pqc elvm if pzlp gblrk, akrlomk zk zle lfpiriglpke pzlp, if pzk flpojlb rcojmk cs knkfpm, morz qcobe ak pzk rcfeorp cs nkjriftkpcjiu, bklnkm pzk ljdv ofekj gjkpkfmk cs jlimift jkrjoipm lfe rlnlbjv" \end{code}

Our decryption function:

\begin{code} decrypt = id \end{code}

The original message was:

\eval{decrypt cyphertext}

\end{document}

-------------------------------------

Converting this to .tex with lhs2TeX and to .pdf with pdflatex produces a PDF in which both instances of the cyphertext go off the right edge of the page.

Is there any way to tell lhs2TeX to allow/force line wrap within code blocks and eval-statements?

Thank you very much for any help!

David

P.S.: I have only found one prior discussion of my question (http://tex.stackexchange.com/questions/15048/how-to-typeset-a-multiline-text...) but to my understanding no real answer came out of that.
