API documentation can be found on Hackage. For detailed explanation of the library design see paper "Hoopl: A Modular, Reusable Library for Dataflow Analysis and Transformation"

To build the library run:

cabal configure
cabal build
cabal install --enable-documentation

To run the tests in the testing/ folder run:

cabal configure --enable-tests
cabal test

To run the tests with the test coverage report run:

cabal configure --enable-tests --enable-coverage
cabal test

You'll need a Haskell Platform, which should include appropriate versions of Cabal and GHC.

Please follow Johan Tibell's Haskell Style Guide for all new/modified code.

In order to facilitate GHC development's workflow, the version in hoopl.cabal is to be bumped as soon as a change requires a respective version bump (according to the PVP) relative to the last released hoopl version.

1. Make sure hoopl passes Travis for all GHC versions in the build-matrix
2. Update Changelog (& git commit)
3. Generate source tarball via cabal sdist and upload a candidate to Hackage (see note below), and inspect the result.
4. If everything checks out, make an annotated and GPG-signed Git release tag: git tag -a -s v${VER} -m "hoopl ${VER}"
5. Publish (there's a button for that on Hackage) the package candidate
6. Work on next release

Note: To upload to Hackage,

cabal sdist
cabal upload dist/hoopl-*.tar.gz

However, it's recommended use the Hackage feature for uploading a candidate.
