### Type Members

1. #### class CommandLine extends CommandLineConfig

   An instance of a command line, parsed according to a Spec.

2. #### trait CommandLineConfig extends AnyRef

3. #### abstract class FromString [+T] extends PartialFunction[String, T]

   A general mechanism for defining how a command line argument (always a String) is transformed into an arbitrary type.

   A general mechanism for defining how a command line argument (always a String) is transformed into an arbitrary type. A few example instances are in the companion object, but in general either IntFromString will suffice or you'll want custom transformers.

4. #### trait Instance extends Spec

   The trait mixed into each instance of a specification.

   The trait mixed into each instance of a specification.

5. #### trait Interpolation extends AnyRef

   Interpolation logic for generated files.

   Interpolation logic for generated files. The idea is to be able to write in terms of @@THIS@@ and @@THAT@@ and the reference specification knows enough to perform the substitutions. Warrants expansion.

6. #### trait Property extends Reference

7. #### class PropertyMapper extends ((String, String)) ⇒ List[String]

   Contains logic for translating a property key/value pair into equivalent command line arguments.

   Contains logic for translating a property key/value pair into equivalent command line arguments. The default settings will translate, given programInfo.runner == "foo" :

   foo.bar=true to --bar // if --bar is unary foo.bar=quux to --bar quux // if --bar is binary

8. #### trait Reference extends Spec

   Mixes in the specification trait and uses the vals therein to side-effect private accumulators.

   Mixes in the specification trait and uses the vals therein to side-effect private accumulators. From this emerges formatted help, lists of unary and binary arguments, an apply which can creates instances of the specification, and etc.

9. #### trait Spec extends AnyRef

   This trait works together with others in scala.tools.cmd to allow declaratively specifying a command line program, with many attendant benefits.

   This trait works together with others in scala.tools.cmd to allow declaratively specifying a command line program, with many attendant benefits. See scala.tools.cmd.DemoSpec for an example.

### Value Members

1. #### object CommandLineParser

   A simple (overly so) command line parser.

   A simple (overly so) command line parser. !!! This needs a thorough test suite to make sure quoting is done correctly and portably.

2. #### object FromString

3. #### object Interpolation

4. #### object Meta

   Meta-options for command line tools.

   Meta-options for command line tools. We could have all kinds of additional goodness here, but for now it's completion and script generation. See Demo for example usage.

5. #### object Opt

   Machinery for what amounts to a command line specification DSL.

   Machinery for what amounts to a command line specification DSL. It is designed so the same specification trait can be used for two different purposes: generating a singleton specification object (trait Reference) and providing well typed vals for every configurable option in response to any given set of arguments (trait Instance).
