binary-parsers
==============
[](http://hackage.haskell.org/package/binary-parsers)
[](https://travis-ci.org/winterland1989/binary-parsers)
This package extends [binary](http://hackage.haskell.org/package/binary) with parsec/attoparsec style parsing combinators. It's useful when you want to deal with various binary format, and it's very fast. You can now write more complex `Binary` instances using comprehensive combinators, with serialisation packages like blaze-texual.
Binary's `Get` monad is designed to perform best on non-backtracking cases, but it still provides fast backtracking support via `Alternative` instance, it's overall an excellent alternative to attoparsec if you only deal with `ByteString`.
Building
--------
binary-parsers comes with a test suite modified from attoparsec, and a JSON parsing benchmarks. Here you go:
```
git clone https://github.com/winterland1989/binary-parsers.git
cd binary-parsers
cabal update
cabal configure --enable-tests --enable-benchmarks
cabal build
```
Run the test suite and benchmarks.
```
cabal test
cabal bench
```
