This ensures we run in a clean directory, using our real distribution. It finds bugs like @internal APIs needed to type-check in the offline compiler, as well as problems in package.json. Also move tsc-wrapped under tools/@angular |

tsc-wrapped
This package is an internal dependency used by @angular/compiler-cli. Please use that instead.
This is a wrapper around TypeScript's tsc program that allows us to hook in extra extensions.
TypeScript will eventually have an extensibility model for arbitrary extensions. We don't want
to constrain their design with baggage from a legacy implementation, so this wrapper only
supports specific extensions developed by the Angular team:
- tsickle down-levels Decorators into Annotations so they can be tree-shaken
- tsickle can also optionally produce Closure Compiler-friendly code
- ./collector.ts emits an extra
.metadata.jsonfile for every.d.tsfile written, which retains metadata about decorators that is lost in the TS emit - @angular/compiler-cli extends this library to additionally generate template code
TypeScript Decorator metadata collector
The .d.ts format does not preserve information about the Decorators applied to symbols.
Some tools, such as Angular 2 template compiler, need access to statically analyzable
information about Decorators, so this library allows programs to produce a foo.metadata.json
to accompany a foo.d.ts file, and preserves the information that was lost in the declaration
emit.
