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 equal signs are turned into
\heading
s.
- Paragraphs followed by a line of dashes are turned into
\subheading
s.
- Consecutive paragraphs starting
*
are turned into an itemize
environment.
- 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.

Installation
These are standard installation instructions.
Last update of installation instructions: 2021-05-29.
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, 8.10.4, 9.0.1.
