I’m proud to announce the first release of my lhs2TeX-hl tool. For us who fancy using colours in our presentations or papers this should now go a whole lot easier. Go to the lhs2TeX-hl homepage!

Install it like this:

[bash] > cabal install lhs2TeX-hl [/bash]

lhs2TeX-hl is run before you run lhs2TeX and you supply it with the input file and the output file. A typical execution would look like this:

[bash] > lhs2TeX-hl -o MyPaper.fmt MyPaper.lhs > lhs2TeX -o MyPaper.Tex MyPaper.lhs > pdflatex MyPaper.tex [/bash]

It’s important to note here that you should’ve added the following line to your MyPaper.lhs file:

%include MyPaper.fmt

And that you have the following commands defined in your latex file:

\lhsCHkeyword
\lhsCHprelude
\lhsCHtype
\lhsCHlitNumber
\lhsCHconstructor
\lhsCHfunction
\lhsCHinfixoperator

For example, like this:

\definecolor{datatype}{RGB}{42,0,217}
\definecolor{class}{RGB}{197,11,16}
\definecolor{fieldname}{RGB}{0,0,162}
\definecolor{prelude}{RGB}{64,80,117}
\definecolor{numeral}{RGB}{0,0,205}
\definecolor{infixoperator}{RGB}{42,0,217}
\definecolor{constructor}{RGB}{0,161,0}
\definecolor{keyword}{RGB}{229,120,0}
\definecolor{special1}{RGB}{159,138,0}

\newcommand{\lhsCHfunction}[1]{\color{infixoperator}{{#1}}}
\newcommand{\lhsCHinfixoperator}[1]{\color{infixoperator}{{#1}}}
\newcommand{\lhsCHprelude}[1]{\color{prelude}{\mathbf{#1}}}
\newcommand{\lhsCHkeyword}[1]{\color{keyword}{\textbf{#1}}}
\newcommand{\lhsCHconstructor}[1]{\color{constructor}{\textbf{#1}}}
\newcommand{\lhsCHlitNumber}[1]{\color{numeral}{{#1}}}
\newcommand{\lhsCHtype}[1]{\color{datatype}{{#1}}}

And then you might end up with something that looks like this:
