sbt-paradox-project-info

A paradox directive that includes standardised project information in the generated documentation.

Usage

Add the Paradox plug-in as sbt plug-on

addSbtPlugin("com.lightbend.paradox" % "sbt-paradox-project-info" % <latest>)

Create a project info file in project/project-info.conf using HOCON format:

project-info {
  # version is overridden from the `projectInfoVersion` key (which defaults to sbt's project version)
  version: "current"
  scala-versions: ["2.12", "2.13"]
  jdk-versions: ["OpenJDK 8"]
  core {
    title: "The core project"
    // if undefined, sbt's crossScalaVersions are used
    scala-versions: ${project-info.scala-versions}
    jdk-versions: ${project-info.jdk-versions}
    jpms-name: "alpakka.core"
    snapshots: {
      text: "Snapshots are available"
      url: "snapshots.html"
      new-tab: false
    }
    issues: {
      url: "https://github.com/lightbend/sbt-paradox-project-info/issues"
      text: "Github issues"
    }
    release-notes: {
      url: "https://github.com/lightbend/sbt-paradox-project-info/releases"
      text: "Github releases"
    }
    api-docs: [
      {
        text: "Scaladoc"
        url: "https://developer.lightbend.com/docs/api/alpakka/"${project-info.version}"/akka/stream/alpakka/index.html"
      }
    ]

    ]
  }
}

Full Source

Use the @@project-info directive in the Paradox markdown files and reference the project by its sbt projectId (when using the project sbt macro it is the name of the val).

# The Test Kit

@@project-info { projectId="core" }

The quick brown fox...

Example

Readiness Levels

Readiness levels is a convenient way to show the support for different projects. In order to use readiness levels you first need to specify what they mean and how to render them, i.e.

import com.lightbend.paradox.projectinfo._
import com.lightbend.paradox.projectinfo.ParadoxProjectInfoPluginKeys._

readinessLevels ++= Map(
  "Supported" -> new ReadinessLevel {
    val name = "<b>This project is supported</b>"
  },
  "NotSupported" -> new ReadinessLevel {
    val name = "<b>This project is not supported</b>"
  }
)

It's also possible to abstract away the readinessLevels setting into a sbt plugin which is convenient if you are using the same configured levels in multiple projects (typical for an organization/company). For an example of this have a look here.

Then in your project/project-info.conf you can specify these readiness levels using the levels config path, i.e.

project-info {
  # version is overridden from the `projectInfoVersion` key (which defaults to sbt's project version)
  version: "current"
  scala-versions: ["2.12", "2.13"]
  jdk-versions: ["OpenJDK 8"]
  core {
    title: "The core project"
    // if undefined, sbt's crossScalaVersions are used
    scala-versions: ${project-info.scala-versions}
    jdk-versions: ${project-info.jdk-versions}
    jpms-name: "alpakka.core"
    snapshots: {
      text: "Snapshots are available"
      url: "snapshots.html"
      new-tab: false
    }
