This patch refactors the interpolation parser to do so iteratively
rather than using a regex. Doing so prepares us for supporting granular
recovery on poorly-formed interpolations, for example when an
interpolation does not terminate (`{{ 1 + 2`) or is not terminated
properly (`{{ 1 + 2 {{ 2 + 3 }}`).

The compiler maintains an internal dependency graph of all resource
dependencies for application source files. This information can be useful
for tools that integrate the compiler and need to support file watching.
This change adds a `getResourceDependencies` method to the
`NgCompiler` class that allows compiler integrations to access resource
dependencies of files within the compilation.

This patch adds support for recovering well-formed (and near-complete)
ASTs for semantically malformed keyed reads and keyed writes. See the
added tests for details on the types of semantics we can now recover;
in particular, notice that some assumptions are made about the form of
a keyed read/write intended by a user. For example, in the malformed
expression `a[1 + = 2`, we assume that the user meant to write a binary
expression for the key of `a`, and assign that key the value `2`. In
particular, we now parse this as `a[1 + <empty expression>] = 2`. There
are some different interpretations that can be made here, but I think
this is reasonable.
The actual changes in the parser code are fairly minimal (a nice
surprise!); the biggest addition is a `writeContext` that marks whether
the `=` operator can serve as a recovery point after error detection.

Previously, when a heading was longer than the Table of Content's (TOC)
width and it had to be wrapped into multiple lines, it was hard to
distinguish the subsequent lines from other TOC entries (i.e. other
headings).
This commit makes it easier to visually distinguish wrapped heading
lines from other headings by reducing the spacing between wrapped lines
of the same heading (making it more obvious that they belong together).

Updates to rules_nodejs 2.2.0. This is the first major release in 7 months and includes a number of features as well
as breaking changes.
Release notes: https://github.com/bazelbuild/rules_nodejs/releases/tag/2.0.0
Features of note for angular/angular:
* stdout/stderr/exit code capture; this could be potentially be useful
* TypeScript (ts_project); a simpler tsc rule that ts_library that can be used in the repo where ts_library is too
heavy weight
Breaking changes of note for angular/angular:
* loading custom rules from npm packages: `ts_library` is no longer loaded from `@npm_bazel_typescript//:index.bzl`
(which no longer exists) but is now loaded from `@npm//@bazel/typescript:index.bzl`
* with the loading changes above, `load("@npm//:install_bazel_dependencies.bzl", "install_bazel_dependencies")` is
no longer needed in the WORKSPACE which also means that yarn_install does not need to run unless building/testing
a target that depends on @npm. In angular/angular this is a minor improvement as almost everything depends on @npm.
* @angular/bazel package is also updated in this PR to support the new load location; Angular + Bazel users that
require it for ng_package (ng_module is no longer needed in OSS with Angular 10) will need to load from
`@npm//@angular/bazel:index.bzl`. I investigated if it was possible to maintain backward compatability for the old
load location `@npm_angular_bazel` but it is not since the package itself needs to be updated to load from
`@npm//@bazel/typescript:index.bzl` instead of `@npm_bazel_typescript//:index.bzl` as it depends on ts_library
internals for ng_module.
* runfiles.resolve will now throw instead of returning undefined to match behavior of node require
Other changes in angular/angular:
* integration/bazel has been updated to use both ng_module and ts_libary with use_angular_plugin=true.
The latter is the recommended way for rules_nodejs users to compile Angular 10 with Ivy. Bazel + Angular ViewEngine is
supported with @angular/bazel <= 9.0.5 and Angular <= 8. There is still Angular ViewEngine example on rules_nodejs
https://github.com/bazelbuild/rules_nodejs/tree/stable/examples/angular_view_engine on these older versions but users
that want to update to Angular 10 and are on Bazel must switch to Ivy and at that point ts_library with
use_angular_plugin=true is more performant that ng_module. Angular example in rules_nodejs is configured this way
as well: https://github.com/bazelbuild/rules_nodejs/tree/stable/examples/angular. As an aside, we also have an
example of building Angular 10 with architect() rule directly instead of using ts_library with angular plugin:
https://github.com/bazelbuild/rules_nodejs/tree/stable/examples/angular_bazel_architect.
NB: ng_module is still required for angular/angular repository as it still builds ViewEngine & @angular/bazel
also provides the ng_package rule. ng_module can be removed in the future if ViewEngine is no longer needed in
angular repo.
* JSModuleInfo provider added to ng_module. this is for forward compat for future rules_nodejs versions.
@josephperrott, this touches `packages/bazel/src/external.bzl` which will make the sync to g3 non-trivial.

This commit re-organizes the `tslint.json` configuration file to more

apps. This makes it easier to see the difference with new CLI versions
in the future and keep our `tslint.json` up-to-date (while keeping our
own rules).

This commit only re-orders rules and removes redundant ones. It does not
change the linting behavior.

This commit adds the `AstHost` interface, along with implementations for
both Babel and TS.
It also implements the Babel vesion of the `AstFactory` interface, along
with a linker specific implementation of the `ImportGenerator` interface.
These classes will be used by the new "ng-linker" to transform prelinked
library code using a Babel plugin.

Issue triage _currently_ requires a component to be set and one of the following to be true for an issue to be
considered triaged:
* Marked as a bug _and_ has a severity _and_ has a frequency
* Mark as a feature
* Marked as a refactor
* Marked as a discussion
* Marked as "confusing"
* Marked as "use-case"
This PR changes the rules so that (in addition to the component), triage
requires:
* A priority label (P0 through P5)
* Marked as a feature
* Marked as a discussion
Triage may also apply additional, optional info labels to issues.
[This document outlines the new priority
scheme](https://docs.google.com/document/d/1mN2zWsr1pxChSTHC7UkOgl4PhhuoFONtG_zcMWeqLwA/preview).
While this PR is focused on issue triage and not PR triage, I have
changed the PR section triage to remove reference to the "effort: *" and
"risk: *" labels. Looking through recent PRs, Kapunahele is the only
person applying these, so it's clear that this bit is no longer widely
practiced.
This is just one step in the always-ongoing process of managing GitHub
labels. More adjustments will come over time. In writing this PR, I have
already unearthed a few more areas that can be polished in follow-ups.

In certain circumstances (errors during component constructor) the router outlet may not be activated before
redirecting to a new route. If the new route requires running guards and resolvers the current logic will throw
when accessing outlet.component due to an isActivated check within the property getter. This update brings the
logic inline with deactivateRouterAndItsChildren, namely checking outlet.isActivated before trying to access
outlet.component.

To verify the correctness of the linker output, we leverage the existing
compliance tests. The plan is to test the linker by running all compliance
tests using a full round trip of pre-linking and subsequently post-linking,
where the generated code should be identical to a full AOT compile.
This commit adds an additional Bazel target that runs the compliance
tests in partial mode. Follow-up work is required to implement the logic
for running the linker round trip.

This is a precursor to introducing the Angular linker. As an initial

Currently it is impossible to determine the source of a binding that
generates `BoundAttribute` because all bound attributes generated from a
microsyntax expression share the same source span.
For example, in
```html
<div *ngFor="let item of items; trackBy: trackByFn"></div>
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
source span for all `BoundAttribute`s generated from microsyntax
```
the `BoundAttribute` for both `ngForOf` and `ngForTrackBy`
share the same source span.
A lot of hacks were necessary in View Engine language service to work
around this limitation. It was done by inspecting the whole source span
then figuring out the relative position of the cursor.
With this change, we introduce a flag to set the binding span as the
source span of the `ParsedProperty` in Ivy AST.
This flag is needed so that we don't have to change VE ASTs.
Note that in the binding parser, we already set `bindingSpan` as the
source span for a `ParsedVariable`, and `keySpan` as the source span for
a literal attribute. This change makes the Ivy AST more consistent by
propagating the binding span to `ParsedProperty` as well.

In preparation for the Ivy Language service, add the same properties to AppComponent that appear in

This commit adds an API to `NgCompiler`, a method called
`getComponentsWithTemplateFile`. Given a filesystem path to an external
template file, it retrieves a `Set` (actually a `ReadonlySet`) of component
declarations which are using this template. In most cases, this will only be
a single component.
This information is easily determined by the compiler during analysis, but
is hard for a lot of Angular tooling (e.g. the language service) to infer
independently. Therefore, it makes sense to expose this as a compiler API.

Previously, when updating the dependency versions in
`aio/tools/examples/shared/package.json` (which contains all
dependencies used in docs examples projects), one had to manually go
through all boilerplate directories and update the `package.json` files
with the same versions.
This commit simplifies this task by automating it via a Node.js script.
