Hi Artem, I answer with inline lhs2Tex file. Hopefully it helps in your typed-code type-settings! cheers, Oleg. \documentclass{article} %include polycode.fmt \usepackage{hyperref} \hypersetup{pdfborder={0 0 0}} % in lhs2TeX.style there are % % \newcommand{\Conid}[1]{{\mathit #1}} % \newcommand{\Varid}[1]{{\mathit #1}} % \newcommand{\anonymous}{\_} % % We can renew these \usepackage{xcolor} \definecolor{darkred}{rgb}{.5,0,0} \definecolor{darkgreen}{rgb}{0,0.5,0} \definecolor{darkblue}{rgb}{0,0,.5} \definecolor{color4}{rgb}{0,.4,.4} \definecolor{color5}{rgb}{.4,.4,0} \renewcommand{\Conid}[1]{{\color{darkblue}\mathit #1}} % however types and constructors look the same, we can differentiate them though %format Foo = "{\color{darkred}\mathit Foo}" %format MkFoo = "{\color{darkgreen}\mathit Foo}" % Note how I "cheat" making MkFoo render as Foo! % We can also highlight operators %format + = "\mathbin{\color{color4}+}" % or symbols (note I also make thing look prettier)" %format plusFoo = "{\color{color5}\mathit plus_{Foo}}" %format ColorsInLhs2TeX = "{\text{Colors in lhs2\TeX}}" \begin{document} An example of colorful lhs2\TeX\ file. See the source at \url{https://github.com/phadej/gists/blob/master/posts/2018-06-21-colors-in-lhs2tex.tex}% \footnote{It's named tex to trick \emph{Pandoc} in my blog setup}, and the result PDF at \url{https://github.com/phadej/gists/blob/master/pdf/ColorsInLhs2TeX.pdf} \begin{code} module ColorsInLhs2TeX where newtype Foo = MkFoo Int plusFoo :: Foo -> Foo -> Int plusFoo (MkFoo n) (MkFoo m) = n + m \end{code} \end{document} On 21.06.2018 18:29, Artem Pelenitsyn wrote:
Dear Cafe,
In his recent Stitch manuscript, https://cs.brynmawr.edu/~rae/papers/2018/stitch/stitch.pdf https://cs.brynmawr.edu/%7Erae/papers/2018/stitch/stitch.pdf Richard Eisenberg mentions that he uses lhs2TeX to typeset Haskell listings, but I'm not aware of the support for colors in lhs2TeX. Can anyone suggest how to get such a nice code highlighting (presumably with lhs2TeX).
-- Best wishes, Artem
