Tupler
A macro that converts case classes into a sequence of string tuples e.g. Seq[(String, String)]. The implementation
is naive and just calls .toString() on the fields of the case class.
Usage
The method Tupler.toTupleSeq is used to convert the case class, it requires an implicit Writes instance. The
Writes may be created using the Tupler.tupleWrites macro.
Example
case class Cat(name: String, colour: String, age: Int)
implicit val writes: Writes[Cat] = Tupler.tupleWrites[Cat]
val floydCat = Cat("floyd", "grey", 6)
val result = Tupler.toTupleSeq(floydCat)
assert(result === Seq(("name", "Floyd"), ("colour", "grey"), ("age", "6")))
Installing Tupler
-
clone the repository
-
publish locally
`sbt publish-local`
- include the dependency in your (Scala v2.10) project
`libraryDependencies += "com.tysonjh" %% "tupler" % "0.1-SNAPSHOT"`
Notes
Tupler is in very early development stages. Currently it's purpose is to sate my interest with macros. The intent is to explore its usefulness towards creating URL parameters.
