sbt-appengine 0.4.0

sbt-appengine + sbt-revolver = hot reloading dev server

One glaring omission in sbt-appengine when it was ported from @Yasushi's sbt-appengine-plugin was the ability to run development server locally from sbt shell.

sbt-appengine 0.4.0 adds a new task:

> appengine-dev-server

This (re)starts development server in the background managed by sbt-revolver. This also allows triggered redeployment:

> ~ appengine-dev-server

But wait there's more! By installing JRebel (there's a free Scala license) and setting the path as:

export JREBEL_PATH=/Applications/ZeroTurnaround/JRebel/jrebel.jar

development server launches under JRebel. This allows hot reloading:

> appengine-dev-server
> ~ package-war

You change your code, and it reflects to http://localhost:8080/ automatically. This feature was implemented by @philcali and @eed3si9n.

how to install

The use of sbt-revolver requires an additional resolver in plugins.sbt:

addSbtPlugin("com.eed3si9n" % "sbt-appengine" % "0.4.0")

resolvers ++= Seq(
  "spray repo" at "http://repo.spray.cc",
  Resolver.url("sbt-plugin-releases",
    url("http://scalasbt.artifactoryonline.com/scalasbt/sbt-plugin-releases/"))(Resolver.ivyStylePatterns)
)

treehugger 0.1.2

Self type annotations

Adds withSelf(...) to define self type annotations: 

CLASSDEF("C") withSelf("self", "T1", "T2") := BLOCK(
  VAL("x") := REF("self")
)

Type expressions

Adds TYPE_WITH(typ, ...) to define refined types. 

VAL("x", TYPE_REF("A") TYPE_WITH "B")

Adds TYPE_SINGLETON(tree) to define singleton types. 

VAL("x", TYPE_SINGLETON(THIS))

Bug fixes and minor enhancements

  • Fixes symbol and type name printing. #8
  • Adds withParents(...) to OBJECTDEF(...) and CASEOBJECTDEF(...). #10
  • Fixes TYPE_MAP to generate Map instead of scala.collection.Map.

treehugger 0.1.1

Function type contructors

Several ways were added to create function types. 

typ1 TYPE_=> typ2
TYPE_FUNCTION(typ, ..., r)
TYPE_FUNCTION(typ :: Nil, r)

Now accepting Iterables

DSL was expanded to accept Iterable[A] where it accepted vararg of A. Also implicit conversions were expanded to handle iterables. These changes should minimize explicit conversions that were necessary in the previous version: 

withTypeParams(sym.pipeParams map {TYPEVAR(_)})

Bug fixes and minor enhancements

  • Fixes param modifiers not printing. #1
  • Fixes passing args to parent constructors. #2
  • Adds withParams(...) to DEF(sym). #3
