agda2lagda: Convert Agda/Haskell text to literate Agda/Haskell text

Generate a LaTeX literate Agda/Haskell script from an Agda/Haskell script.

  • Single line comments are turned into ordinary LaTeX.

    • Paragraphs followed by a line of dashes are turned into \headings.
    • At the end of the file, extra block comment terminators are removed.
  • Comment blocks, if started on the 0th column, count as commenting out. These will be turned into TeX comments. Nested comments are not recognized.

  • The rest is interpreted as code and wrapped in a code environment.

Example: agda2lagda Foo.agda

Input: Foo.agda

Installation

These are standard installation instructions.

Last update of installation instructions: 2020-11-01.

From stackage.org

Requires stack.

stack update
stack install agda2lagda

From hackage.haskell.org

Requires GHC >= 8.0 and the Haskell Cabal.

cabal update
cabal install agda2lagda

From the repository

git clone https://github.com/andreasabel/agda2lagda.git
cd agda2lagda
cabal install

Alternatively to the last line, you can use stack. E.g. if you have GHC 8.10.2 installed, you can use this compiler as follows:

stack install --system-ghc --stack-yaml stack-8.10.2.yaml

Alternatively, stack can install the compiler for you:

stack install --stack-yaml stack-xx.yy.zz.yaml

The xx.yy.zz is a placeholder for the GHC version, choose one (for which there is a .yaml file).

At the time of writing, installation with these GHC versions has been tested: 8.0.2, 8.2.2, 8.4.4, 8.6.5, 8.8.4, 8.10.2.
