Urimplicit is a really simple Scala library that provides useful, implicit augmentations for the Java URI class.

To install add the following line to your SBT configuration:

libraryDependencies += "me.gladwell" %% "urimplicit" % "0.3.0"

To enable simply import the library into scope:

scala> import urimplicit._

This gives you the ability to concatenate relative URIs together using the + operator:

scala> new URI("http://example.org")
res0: java.net.URI = http://example.org

scala> res0 + "/test"
res1: urimplicit.URI = http://example.org/test

scala> new URI("/main")
res2: java.net.URI = /main

scala> res1 + res2
res4: urimplicit.URI = http://example.org/main

It also provides a useful URI companion class constructor to make URI creation more succinct:

scala> URI("http://example.org")
res0: java.net.URI = http://example.org

This library also provides the Uri object which can be used in pattern matching on URI objects and strings:

scala> def isAddress(address: String): Boolean =
     address match {
     case URI(_,_)  => true
     case _         => false
     }
isAddress: (address: String)Boolean

scala> isAddress("http://localhost:8080")
res0: Boolean = true

scala> isAddress("unknown")
res1: Boolean = false

You can also use the pattern matcher to extract host information from a URI:

scala> def host(address: URI): Option[String] =
     address match {
     case URI(_, host)  => Some(host)
     case _             => None
}
host: (address: String)Option[String]

scala> host(URI("http://localhost:8080"))
res2: Option[String] = Some(localhost)
