Decorator TS parameters. New js rug instance per invocation #229

[kipz]

• add support for decorated parameters
• decorate actually just populates the 'parameters' property
  • totally backwards compatible and interchangeable

import {Project} from '@atomist/rug/model/Core'
import {ProjectEditor} from '@atomist/rug/operations/ProjectEditor'
import {File} from '@atomist/rug/model/Core'
import {parameter} from '@atomist/rug/operations/RugOperation'

class SimpleEditor implements ProjectEditor {
    name: string = "Simple"
    description: string = "A nice little editor"

    @parameter({pattern: "^.*$$", description: "foo bar"})
    content: string = "Test String";

    @parameter({pattern: "^\\d+$$", description: "A nice round number"})
    amount: number = 10;

    @parameter({pattern: "^\\d+$$", description: "A nice round number"})
    nope: boolean;

    edit(project: Project) {
       if(this.amount != 10) {
          throw new Error("Number should be 10!");
       }
       if(this.content != "woot") {
          throw new Error("Name should be woot");
       }
    }
  }
export let editor = new SimpleEditor()

I love the model. Would like to see some timing tests before merging.

Would be nicer to match

[johnsonr]

Would be nicer without casting.

No need to do it in this PR, but I added ability to load a TypeScript side file from the class path. Makes it easier to edit the TS. For example,

val jsed = TestUtils.editorInSideFile(this, "SimpleBanana.ts")

Where the TypeScript file is under test resources in the same package.
