Calls to methods annotated with `@pragma('dart2js:resource-identifier')` are tracked, with their primitive constant arguments, through to the `.js` file which contains the call.
- JavaScript annotations are attached to the JavaScript AST node for
the call.
- At the time of `.js` file printing, the JavaScript annotations are
collected and attributed to the file. This allows the construction
of a map from `.js` files to the 'resource identifiers' contained in
the file.
- Alongside the `main.js` file the resource identifiers are emitted in
a file called `main.js.resources.json`. This is controlled by the
`--write-resources` command line option.
- Serialization of JavaScript ASTs now serializes the attached
JavaScript annotations.
- The internal method used to implement deferred library loading is
annotated, to allow analysis of which deferred library parts load
other libraries.
pkg/js_ast was tweaked to make the pkg/js_ast was tweaked to make the
- pkg/js_ast was tweaked to make propagating the JavaScript annotations through the async transforms easier.
TODO:
- Annotate const constructors
- Add golden-style tests
