=========

This started out as a lightweight replacement for those large DI frameworks

when all you need is to wire up a few objects. Features:

- no transitive dependencies apart from scala-library

- can instantiate any POJO (constructor args or bean setters)

- provides Configuration trait for enhancing user experience if desired

- configuration file format extremely easy to read and write

Example configuration file syntax:

================================================================================

configure SomeThing bob

  with SomeProperty 42

  with OtherProperty "hello world!"

end

configure OtherThing constructorDemo

  construct arg1

  construct reference bob

  with Property configure Helper with Name Alice end

  call start

end

================================================================================

Whitespace is arbitrary except within double-quoted strings. Names are given as

second argument to "configure" and may be referenced only after their

corresponding "end" token (no passing around unfinished objects). The list of

constructors is scanned to find one which is compatible with the arguments

given, where literals are tried to parse using java.lang.Integer.valueOf() and

friends. "with Prop" tries calling a single-argument method named "setProp"

which is compatible with the given argument type. After all is set and done,

parameterless methods may be called by specifying "call".

Most of the above is skipped for classes implementing the Configurable

interface, which may enable setter invocations by overriding useBeanSetters()

to return "true". Constructor arguments are not legal, as are method calls. All

arguments not successfully passed into bean setters are wrapped up and passed

into the configure() method. The finished object must be returned wrapped in a

Success. This scheme allows direct configuration as well as factories.

See COPYING for licensing information.

Have Fun!
