+# What is Haskell?
|
|
|
+
|
|
|
+[Haskell](http://www.haskell.org) is a [lazy](http://en.wikibooks.org/wiki/Haskell/Laziness), functional, statically-typed programming language with advanced type system features such as higher-rank, higher-kinded parametric [polymorphism](http://en.wikibooks.org/wiki/Haskell/Polymorphism), monadic [effects](http://en.wikibooks.org/wiki/Haskell/Understanding_monads/IO), generalized algebraic data types ([GADT](http://en.wikibooks.org/wiki/Haskell/GADT)s), flexible [type classes](http://en.wikibooks.org/wiki/Haskell/Advanced_type_classes), associated [type families](http://en.wikipedia.org/wiki/Type_family), and more.

|
+Haskell's [`ghc`](http://www.haskell.org/ghc) is a [portable](https://ghc.haskell.org/trac/ghc/wiki/Platforms), [optimizing](http://benchmarksgame.alioth.debian.org/u64q/haskell.php) compiler with a foreign-function interface ([FFI](http://en.wikibooks.org/wiki/Haskell/FFI)), an [LLVM backend](https://www.haskell.org/ghc/docs/7.8.3/html/users_guide/code-generators.html), and sophisticated runtime support for [concurrency](http://en.wikibooks.org/wiki/Haskell/Concurrency), explicit/implicit [parallelism](http://community.haskell.org/~simonmar/pcph/), runtime [profiling](http://www.haskell.org/haskellwiki/ThreadScope), etc. Other Haskell tools like [`criterion`](http://www.serpentine.com/criterion/tutorial.html), [`quickcheck`](https://www.fpcomplete.com/user/pbv/an-introduction-to-quickcheck-testing), [`hpc`](http://www.haskell.org/haskellwiki/Haskell_program_coverage#Examples), and [`haddock`](http://en.wikipedia.org/wiki/Haddock_(software)) provide advanced benchmarking, property-based testing, code coverage, and documentation generation.

|
|
|
+A large number of production-quality Haskell libraries are available from [Hackage](https://hackage.haskell.org). The [`cabal`](https://www.fpcomplete.com/user/simonmichael/how-to-cabal-install) tool fetches packages and builds projects using the Hackage ecosystem.

+## Contents
|
|
|
+
|
|
|
+This image ships a minimal Haskell toolchain with the following packages:
|
|
|
+
|
|
|
+| package | version |
|
|
|
+|-----------------|------------|
|
|
|
+| `alex` | `3.1.3` |
|
|
|
+| `cabal-install` | `1.20.0.3` |
|
|
|
+| `happy` | `1.19.4` |
|
|
|
+| `ghc` | `7.8.3` |
|
|
|
+
|
|
|
+
|
|
|
+## Usage
|
|
|
+
|
|
|
+* Start an interactive interpreter session with `ghci`:
|
|
|
+
|
|
|
+```
|
|
|
+ $ docker run -it --rm haskell:7.8
|
|
|
+ GHCi, version 7.8.3: http://www.haskell.org/ghc/ :? for help
|
|
|
+ Loading package ghc-prim ... linking ... done.
|
|
|
+ Loading package integer-gmp ... linking ... done.
|
|
|
+ Loading package base ... linking ... done.
|
|
|
+ Prelude>
|
|
|
+```
|
|
|
+
|
|
|
+* Dockerize a [Hackage](http://hackage.haskell.org) app with a Dockerfile inheriting from the base image:
|
|
|
+
|
|
|
+```
|
|
|
+ FROM haskell:7.8
|
|
|
+ RUN cabal update && cabal install MazesOfMonad
|
|
|
+ VOLUME /root/.MazesOfMonad
|
|
|
+ ENTRYPOINT ["/root/.cabal/bin/mazesofmonad"]
|
|
|
+```
|
|
|
+
|
|
|
+* Iteratively develop then ship a Haskell app with a Dockerfile utilizing the
|
|
|
+build cache:
|
|
|
+
|
|
|
+```
|
|
|
+ FROM haskell:7.8
|
|
|
+
|
|
|
+ RUN cabal update
|
|
|
+
|
|
|
+ # Add .cabal file
|
|
|
+ ADD ./server/snap-example.cabal /opt/server/snap-example.cabal
|
|
|
+
|
|
|
+ # Docker will cache this command as a layer, freeing us up to
|
|
|
+ # modify source code without re-installing dependencies
|
|
|
+ RUN cd /opt/server && cabal install --only-dependencies -j4
|
|
|
+
|
|
|
+ # Add and Install Application Code
|
|
|
+ ADD ./server /opt/server
|
|
|
+ RUN cd /opt/server && cabal install
|
|
|
+
|
|
|
+ # Add installed cabal executables to PATH
|
|
|
+ ENV PATH /root/.cabal/bin:$PATH
|
|
|
+
|
|
|
+ # Default Command for Container
|
|
|
+ WORKDIR /opt/server
|
|
|
+ CMD ["snap-example"]
|
|
|
+```
|
|
|
+
|
|
|
+## Examples
|
|
|
+
|
|
|
+See the application snippet above in more detail in the [example snap application](https://github.com/darinmorrison/docker-haskell/tree/master/examples/7.8.3/snap).
