Odds and ends for developers using Lightbend's Play Framework.

Playful offers features its author wishes were part of APIs included with Play Framework. It's starting small and will expand incrementally, focusing first on augmenting the iteratee and JSON libraries.

Everything you'll find here will be tested and considered production-ready (despite the low version number). What's not clear is whether this library will receive maintenance in the long term. (It may turn out to be redundant as Lightbend expands their offerings and adds features.) In the meantime, interested users might consider simply copying and pasting source code directly into their own projects. (Although updates will be published to public repositories.)

Release binaries are by Sonatype. If not already present, add these resolvers to your SBT project configuration:

resolvers += "Sonatype OSS (releases)" at "https://oss.sonatype.org/content/repositories/releases"
resolvers += "Sonatype OSS (snapshots)" at "https://oss.sonatype.org/content/repositories/snapshots"

And add Playful to your dependencies:

libraryDependencies += "com.github.michaelahlers" %% "playful" % "0.1.1-SNAPSHOT"

All contributions—advice, criticism, and assistance—are welcomed and strongly encouraged.

Apart from requiring Oracle's Java SE Development Kit 8 (JDK 8), this project is “batteries included.” Simply start Lightbend Activator from the project's root to get started (installing SBT is optional). It's recommended to use one of the following resources to obtain Java.

• Web Upd8 PPA
  • Best packages for Debian-based distributions (e.g., Debian, Ubuntu, Mint)
• Oracle Java SE Development Kit 8 Downloads
  • Packages for RPM-based distributions (e.g., RHEL, Fedora, CentOS).
  • Installer packages for OS X.
  • Installer packages for Windows.

From an SBT shell, the unit test suite is run with:

test

Specific tests with:

test-only ahlers.michael.playful.iteratee.EnumerateeOpsSpec

Test code coverage reports may be generated with:

;coverage;clean;test;coverageReport

There's currently a beginner's attempt at writing meaningful performance tests using ScalaMeter in src/bench. Benchmarks can be run with:

bench:test

API documentation is available with copious developer notes is included. From an SBT shell, generate it with:
