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

[Dominique Devriese]

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}
