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:

\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:
