MiniAgda

A prototypical dependently typed languages with sized types and variances.

Installation from Hackage

Requires ghc and cabal, for instance via the Haskell Platform or via ghcup. In a shell, type

  cabal update
  cabal install MiniAgda

Installation from Stackage

MiniAgda is not on Stackage because it depends on a specific version of haskell-src-exts rather than the latest version. You can install with stack from source though, see next section.

Installation from source

1. Obtain the sources.

   git clone https://github.com/andreasabel/miniagda
   cd miniagda

2. Checkout the desired version (optional): If you want to build a released version or a branch rather than the latest master, switch to this version/branch.

   git checkout $REF

   E.g. REF = v0.2022.3.11 for version 0.2022.3.11 or REF = unfold for branch unfold.

3. Building and running the tests (optional).

   • With cabal (requires ghc in your PATH):

     cabal build --enable-tests
     cabal test

     After building, you can run MiniAgda locally, e.g.:

     cabal run miniagda -- examples/Gcd/gcd.ma

   • With stack:

     stack build --stack-yaml=stack-$GHCVER.yaml
     stack test  --stack-yaml=stack-$GHCVER.yaml

     At the time of writing (2025-07-23), GHCVER can be any of 9.12, 9.10, 9.8, 9.6, and some older ones.

     After building, you can run MiniAgda locally, e.g.:

     stack run --stack-yaml=stack-9.12.yaml -- examples/Gcd/gcd.ma

     You can copy stack-$GHCVER.yaml for your choice of GHCVER into stack.yaml and drop the --stack-yaml argument from stack invocation.

4. Install.

   • With cabal (requires ghc in your PATH):

     cabal install

   • With stack:

     stack install --stack-yaml=stack-$GHCVER.yaml

   Note that the respective installation directory should be on your PATH.

Examples

See directories test/succeed/ and examples/.
