Add two transform parameters to aid in debugging the transformer
- `mirror_mode`, with values {`debug`, `none`, and `verbose`}
- `init_reflector`, with values {`true`, `false`}
`mirror_mode`:
- `debug`: Allow reflective access, but log a message if it is used
- `none`: Remove reflective access, `throw` if it is used. Default value
- `verbose`: Allow reflective access, log a stack trace if it is used
`init_reflector`: Whether to generate calls to our generated
`initReflector` code.
These will be useful to reveal areas where the transformer is not generating
appropriate code and to quickly see where reflective accesses occur.
When the pub mode is `transform_dynamic`, we run in MirrorMode.debug
with `init_reflector = false`. This is used for testing purposes.
Add a transformer for `di` which generates `.ng_deps.dart` files for all
`.dart` files it is run on. These `.ng_deps.dart` files register
metadata for any `@Injectable` classes.
Fix unit tests for changes introduced by the di transformer.
When using `pub (build|serve) --mode=ngstatic`, we will also generate
getters and setters, parse templates, and remove import of `dart:mirrors`
in the Angular transform. Because this is still relatively immature, we
use the mode to keep it opt-in for now.
Closes#700
Update summary:
- Removes the need for resolution, gaining transform speed at the cost
of some precision and ability to detect errors
- Generates type registrations in the package alongside their declarations
- Ensures that line numbers do not change in transformed user code
