Scaladoc link checker plugin for sbt

sdlc checks links in HTML files against a scaladoc site. Unlike a regular link checker it understands scaladoc's fragment syntax. sdlc only needs HTML files as input and validates all links with a specified prefix, so it should work with any documentation tool that can output HTML (like Ornate or Paradox).

Add to project/plugins.sbt:

addSbtPlugin("com.github.sbt" % "sbt-sdlc" % "0.3.0")

Add add something like this to build.sbt:

lazy val root = project.in(file("."))
  .enablePlugins(SDLCPlugin)

sdlcBase := s"http://slick.typesafe.com/doc/${version.value}/api/"
sdlcCheckDir := (target in com.typesafe.sbt.SbtSite.SiteKeys.makeSite).value
sdlc := (sdlc dependsOn (doc in Compile)).value

Type sdlc to run in sbt.

The following setting keys are available:

    val sdlcDocDir = settingKey[File]("The directory containing scaladoc output")
    val sdlcBase = settingKey[String]("The base URI of the scaladoc output")
    val sdlcCheckDir = settingKey[File]("The directory containing HTML files to check")
    val sdlcVersion = settingKey[String]("The scaladoc format version (2.11/2.12/auto)")

By default the sdlc task does not depend on doc so it won't (re)build the scaladocs automatically. You have to add the dependency yourself (see above) if you want this behavior. sdlcDocDir is set to the scaladoc target directory. sdlcVersion is set to auto in order to auto-detect scaladoc 2.11 (or lower) and 2.12 (or higher) which use different link formats. In most cases you only need to set sdlcBase and sdlcCheckDir.
