Snap is a simple and fast web development framework and server written in Haskell. For more information about Snap, read the README.SNAP.md or visit the Snap project website at http://www.snapframework.com/.

This is top-level project for the Snap Framework, which contains:

• a library allowing Snap applications to recompile actions on the fly in development mode, with no performance loss in production mode.

• a "snaplet" API allowing web applications to be build from composable pieces.

The command-line utility snap for creating initial Snap applications used to be a part of this package. As of version 1.0, the snap command-line utility is no longer provided by this package. It is now provided by the package snap-templates.

After you clone the repository, change to the newly created snap directory and run

git submodule update --init --recursive

This updates all the Snap Framework dependencies to the correct version. The snap library is built using Cabal and Hackage. Now just run

cabal install

from the snap toplevel directory.

The haddock documentation can be built using 'cabal haddock'.

The docs get put in dist/doc/html/.

To build the test suite, run

$ cabal clean
$ cabal configure --enable-tests --enable-library-coverage
$ cabal build
$ cabal install --enable-tests

From here you can invoke the testsuite by running:

$ ./runTestsAndCoverage.sh

The testsuite generates an hpc test coverage report in dist/hpc.

1. Read Tutorial.lhs which is in the project_template/tutorial/src directory of the snap-template package.
2. Generate and read the haddock docs.
3. The test code has the nice property that it actually functions as a pretty good example app and covers a lot of the use cases.
4. If you're interested in the implementation, read design.md.
