[TypeScript] 1 asset handling for [Play 2.0] 2, implemented as an [sbt] 3 plugin (very similar to Play's handling of CoffeeScript and LESS).

The plugin assumes the availability of the tsc - the TypeScript compiler executable. With node.js and npm installed, run

npm install -g typescript

to install tsc globally, thereby installing not only the module, but also the executable.

In your Play application folder, add

resolvers += "Sonatype OSS Snapshots Repository" at "http://oss.sonatype.org/content/groups/public"

addSbtPlugin("com.github.mumoshu" % "play2-typescript" % "0.1.2-SNAPSHOT")

to project/plugins.sbt.

The plugin automatically registers for compilation of app/assets/**/*.ts, that is all typescript files in your app/assets directory.

You may also want to import/export modules or classes across multiple .ts files, enable Google Closure Compiler in your project/Build.scala:

val main = PlayProject(appName, appVersion, appDependencies, mainLang = SCALA).settings(
    // Enable Google Closure Compiler to enable `require()` function utilized by TypeScript to enable importing modules at runtime.
    javascriptEntryPoints <<= baseDirectory(base => base / "app" / "assets" ** "*.js")
  )
)

• compile:resource-generators: The typescript file watcher is being added here
• play-typescript-entry-points: All files matching app/assets/**/*.ts, except files starting in an underscore
• play-typescript-options: A sequence of strings passed to typescript as command-line flags

This plugin is based on Juha Litola's [play-sass][play-sass] plugin for handling Sass assets.
