# json4s-spire: Spire wrappers for Json4s
[json4s-spire][1] is a collection of sane wrappers for basic [spire][2] number types to [json4s][3] Json AST representation, allowing
you to easily decompose spire values to Json and extract Json values into spire values. It is built for scala 2.10 and scala 2.11.
# Installation
Simply add the following dependency to `libraryDependencies`
"org.mdedetrich" %% "json4s-spire" % "1.3.0"
# Usage
[json4s-spire][1] comes with 2 modes, `withDouble` and `withDecimal`. `withDouble` converts `JDouble` to relevant [spire][2] types and vice versa,
where as `withDecimal` converts `JDecimal` to relevant spire types and vice versa
The `implicit val fixedScale` is needed due to the [spire][2] `FixedPoint` type. If you need to change between different `FixedPoint`s, you need
to create a different [json4s][3] `Formats` for each case
## withDecimal
```scala
implicit val fixedScale = FixedScale(10)
val formats = DefaultFormats.withBigDecimal ++ org.json4s.spire.Serializers.withDecimal
```
## withDouble
```scala
implicit val fixedScale = FixedScale(10)
val formats = DefaultFormats.withBigDecimal ++ org.json4s.spire.Serializers.withDouble
```
# TODO
* More non trivial test cases need to be added
