It is a compile-time error if the function immediately enclosing $a$ is not declared asynchronous. However, this error is simply a syntax error, because in the context of a normal function, \AWAIT{} has no special meaning.

'Invalid URL to reach another package',
'''
To reach an asset that belongs to another package, use `package:` URLs in
-Dart code, but in any other language (like HTML or CSS) use relative URLs.
+Dart code, but in any other language (like HTML or CSS) use relative URLs that
+first go all the way to the `packages/` directory.
-These are the rules you must follow to write URLs that refer to files in other
-packages:
-
- * If the file containing the relative URL is an entrypoint under `web`, use
- `packages/package_name/path_to_file`
-
- * If the file containing the URL is under `web`, but in a different directory
- than your entrypoint, walk out to the same level as the entrypoint first,
- then enter the `packages` directory.
-
- **Note**: If two entrypoints include the file under `web` containing the
- URL, either both entrypoints have to live in the same directory, or you need
- to move the file to the `lib` directory.
-
- * If the file containing the URL lives under `lib`, walk up as many levels as
- directories you have + 1. This is because code in `lib/a/b` is loaded from
- `packages/package_name/a/b`.
-
-The rules are easier to follow if you know how the code is laid out for
-Dartium before you build, and how it is laid out after you build it with `pub
-build`. Consider the following example:
-
- package a
- lib/
- |- a1.html
-
- web/
- |- a2.html
-
- package b
- lib/
- |- b1.html
- |- b2/
- |- b3.html
-
- package c
- lib/
- |- c3.html
-
- web/
- |- index.html
- |- index.dart
- |- c1/
- |- c2.html
-
-If your app is package `c`, then `pub get` generates a packages directory under
-the web directory, like this:
-
- web/
- |- index.html
- |- index.dart
- |- c1/
- | |- c2.html
- |- packages/
- |- a/
- | |- a1.html
- |- b/
- | |- b1.html
- | |- b2/
- | |- b3.html
- |- c/
- |- c3.html
-
-Note that no `lib` directory is under the `packages` directory.
-When you launch `web/index.html` in Dartium, Dartium loads `package:` imports from
-`web/packages/`.
-
-If you need to refer to any file in other packages from `index.html`, you can
-simply do `packages/package_name/path_to_file`. For example
-`packages/b/b2/b3.html`. From `index.html` you can also refer to files under the
-web directory of the same package using a simple relative URL, like
-`c1/c2.html`.
-
-However, if you want to load `a1.html` from `c2.html`, you need to reach out to
-the packages directory that lives next to your entrypoint and then load the file
-from there, for example `../packages/a/a1.html`. Because pub generates symlinks
-to the packages directory also under c1, you may be tempted to write
-`packages/a/a1.html`, but that is incorrect - it would yield a canonicalization
-error (see more below).
-
-If you want to load a file from the lib directory of your own package, you
-should also use a package URL. For example, `packages/c/c3.html` and not
-`../lib/c3.html`. This will allow you to write code in `lib` in a way that it
-can be used within and outside your package without making any changes to it.
-
-Because any time you reach inside a `lib/` directory you do so using a
-`packages/` URL, the rules for reaching into other files in other packages are
-always consistent: go up to exit the `packages` directory and go back inside to
-the file you are looking for. For example, to reach `a1.html` from `b3.html`
-you need to write `../../../packages/a/a1.html`.
-
-The motivation behind all these rules is that URLs need to work under many
-scenarios at once:
-
- * They need to work in Dartium without any code transformation: resolving the
- path in the context of a simple HTTP server, or using `file:///` URLs,
- should yield a valid path to assets. The `packages` directory is safe to use
- because pub already creates it next to entrypoints of your application.
-
- * They need to be canonical. To take advantage of caching, multiple URLs
- reaching the same asset should resolve to the same absolute URL.
-
- Also, in projects that use HTML imports (like polymer) tools support that
- you reach a library with either Dart imports or HTML imports, and correctly
- resolve them to be the same library. The rules are designed to allow tools
- to support this.
-
- For example, consider you have an import might like:
-
- <link rel=import href=packages/a/a.html>
-
- where a.html has `<script type="application/dart" src="a.dart">`. If your
- Dart entrypoint also loads `"package:a/a.dart"`, then a tool need to make
- sure that both versions of `a.dart` are loaded from the same URL. Otherwise,
- you may see errors at runtime like: `A is not a subtype of A`, which can be
- extremely confusing.
-
- When you follow the rules above, our tools can detect the pattern in the
- HTML-import URL containing `packages/` and canonicalize the import
- by converting `packages/a/a.dart` into `package:a/a.dart` under the hood.
-
- * They need to continue to be valid after applications are built.
- Technically this could be done automatically with pub transformers, but to
- make sure that code works also in Dartium with a simple HTTP Server,
- existing transformers do not fix URLs, they just detect inconsistencies and
- produce an error message like this one, instead.
+The rules for correctly writing these imports are subtle and have a lot of
+special cases. Please review
+<https://www.dartlang.org/polymer/app-directories.html> to learn
+more.

+/// A structure built from a glob that efficiently lists filesystem entities
+/// that match that glob.
+///
+/// This structure is designed to list the minimal number of physical
+/// directories necessary to find everything that matches the glob. For example,
+/// for the glob `foo/{bar,baz}/*`, there's no need to list the working
+/// directory or even `foo/`; only `foo/bar` and `foo/baz` should be listed.
+///
+/// This works by creating a tree of [_ListTreeNode]s, each of which corresponds
+/// to a single of directory nesting in the source glob. Each node has child
+/// nodes associated with globs ([_ListTreeNode.children]), as well as its own
+/// glob ([_ListTreeNode._validator]) that indicates which entities within that
+/// node's directory should be returned.
+///
+/// For example, the glob `foo/{*.dart,b*/*.txt}` creates the following tree:
+///
+/// .
+/// '-- "foo" (validator: "*.dart")
+/// '-- "b*" (validator: "*.txt"
+///
+/// If a node doesn't have a validator, we know we don't have to list it
+/// explicitly.
+///
+/// Nodes can also be marked as "recursive", which means they need to be listed
+/// recursively (usually to support `**`). In this case, they will have no
+/// children; instead, their validator will just encompass the globs that would
+/// otherwise be in their children. For example, the glob
+/// `foo/{**.dart,bar/*.txt}` creates a recursive node for `foo` with the
+/// validator `**.dart,bar/*.txt`.
+///
+/// If the glob contains multiple filesystem roots (e.g. `{C:/,D:/}*.dart`),
+/// each root will have its own tree of nodes. Relative globs use `.` as their
+/// root instead.

+#### 0.15.0-dev
+ * Added Polymer.forceReady method. This forces a ready state regardless of
+ whether or not there are still polymer-element declarations waiting for
+ their class definitions to be loaded.
+ * Added Polymer.waitingFor method. This returns a list of all polymer-element
+ declarations that are still waiting for their class definitions to be
+ loaded.
+ * Add runtime checking of the waitingFor queue and print to the console if a
+ deadlock situation is suspected to help diagnose the white screen of death.
+ * Added injectBoundHTML instance method. This can be used to dynamically
+ inject html that is bound to your current element into a target element.
+
+#### 0.14.3
+ * Warn if the same css file is inlined more than once,
+ [19996](http://dartbug.com/19996).
+ * Don't start moving elements from head to body until we find the first
+ import, [20826](http://dartbug.com/20826).
+ * Add option to not inject platform.js in the build output
+ [20865](http://dartbug.com/20865). To use, set `inject_platform_js` to
+ false in the polymer transformer config section of your pubspec.yaml:
+
+ transformers:
+ - polymer:
+ inject_platform_js: false
+ ...
+
+#### 0.14.2+1
+ * Fix findController function for js or dart wrapped elements. This fixes
+ event bindings when using paper-dialog and probably some other cases,
+ [20931](http://dartbug.com/20931).
+
+#### 0.14.2
+ * Polymer will now create helpful index pages in all folders containing entry
+ points and in their parent folders, in debug mode only
+ [20963](http://dartbug.com/20963).
+
+#### 0.14.1
+ * The build.dart file no longer requires a list of entry points, and you can
+ replace the entire file with `export 'package:polymer/default_build.dart';`
+ [20396](http://dartbug.com/20396).
+ * Inlined imports from the head of the document now get inserted inside a

<div id="code_transformers_2"><h3>Invalid URL to reach another package <a href="#code_transformers_2">#2</a></h3>
<p>To reach an asset that belongs to another package, use <code>package:</code> URLs in
-Dart code, but in any other language (like HTML or CSS) use relative URLs.</p>
-<p>These are the rules you must follow to write URLs that refer to files in other
-packages:</p><ul><li>
-<p>If the file containing the relative URL is an entrypoint under <code>web</code>, use
-<code>packages/package_name/path_to_file</code></p></li><li>
-<p>If the file containing the URL is under <code>web</code>, but in a different directory
-than your entrypoint, walk out to the same level as the entrypoint first,
-then enter the <code>packages</code> directory.</p>
-<p><strong>Note</strong>: If two entrypoints include the file under <code>web</code> containing the
-URL, either both entrypoints have to live in the same directory, or you need
-to move the file to the <code>lib</code> directory.</p></li><li>
-<p>If the file containing the URL lives under <code>lib</code>, walk up as many levels as
-directories you have + 1. This is because code in <code>lib/a/b</code> is loaded from
-<code>packages/package_name/a/b</code>.</p></li></ul>
-<p>The rules are easier to follow if you know how the code is laid out for
-Dartium before you build, and how it is laid out after you build it with <code>pub
-build</code>. Consider the following example:</p>
-<p> package a</p>
-<pre><code> lib/
- |- a1.html
-
- web/
- |- a2.html
-</code></pre>
-<p> package b</p>
-<pre><code> lib/
- |- b1.html
- |- b2/
- |- b3.html
-</code></pre>
-<p> package c</p>
-<pre><code> lib/
- |- c3.html
-
- web/
- |- index.html
- |- index.dart
- |- c1/
- |- c2.html
-</code></pre>
-<p>If your app is package <code>c</code>, then <code>pub get</code> generates a packages directory under
-the web directory, like this:</p>
-<pre><code> web/
- |- index.html
- |- index.dart
- |- c1/
- | |- c2.html
- |- packages/
- |- a/
- | |- a1.html
- |- b/
- | |- b1.html
- | |- b2/
- | |- b3.html
- |- c/
- |- c3.html
-</code></pre>
-<p>Note that no <code>lib</code> directory is under the <code>packages</code> directory.
-When you launch <code>web/index.html</code> in Dartium, Dartium loads <code>package:</code> imports from
-<code>web/packages/</code>.</p>
-<p>If you need to refer to any file in other packages from <code>index.html</code>, you can
-simply do <code>packages/package_name/path_to_file</code>. For example
-<code>packages/b/b2/b3.html</code>. From <code>index.html</code> you can also refer to files under the
-web directory of the same package using a simple relative URL, like
-<code>c1/c2.html</code>.</p>
-<p>However, if you want to load <code>a1.html</code> from <code>c2.html</code>, you need to reach out to
-the packages directory that lives next to your entrypoint and then load the file
-from there, for example <code>../packages/a/a1.html</code>. Because pub generates symlinks
-to the packages directory also under c1, you may be tempted to write
-<code>packages/a/a1.html</code>, but that is incorrect - it would yield a canonicalization
-error (see more below).</p>
-<p>If you want to load a file from the lib directory of your own package, you
-should also use a package URL. For example, <code>packages/c/c3.html</code> and not
-<code>../lib/c3.html</code>. This will allow you to write code in <code>lib</code> in a way that it
-can be used within and outside your package without making any changes to it.</p>
-<p>Because any time you reach inside a <code>lib/</code> directory you do so using a
-<code>packages/</code> URL, the rules for reaching into other files in other packages are
-always consistent: go up to exit the <code>packages</code> directory and go back inside to
-the file you are looking for. For example, to reach <code>a1.html</code> from <code>b3.html</code>
-you need to write <code>../../../packages/a/a1.html</code>.</p>
-<p>The motivation behind all these rules is that URLs need to work under many
-scenarios at once:</p><ul><li>
-<p>They need to work in Dartium without any code transformation: resolving the
-path in the context of a simple HTTP server, or using <code>file:///</code> URLs,
-should yield a valid path to assets. The <code>packages</code> directory is safe to use
-because pub already creates it next to entrypoints of your application.</p></li><li>
-<p>They need to be canonical. To take advantage of caching, multiple URLs
-reaching the same asset should resolve to the same absolute URL.</p>
-<p>Also, in projects that use HTML imports (like polymer) tools support that
-you reach a library with either Dart imports or HTML imports, and correctly
-resolve them to be the same library. The rules are designed to allow tools
-to support this.</p>
-<p>For example, consider you have an import might like:</p>
-<pre><code><link rel=import href=packages/a/a.html>
-</code></pre>
-<p>where a.html has <code><script type="application/dart" src="a.dart"></code>. If your
-Dart entrypoint also loads <code>"package:a/a.dart"</code>, then a tool need to make
-sure that both versions of <code>a.dart</code> are loaded from the same URL. Otherwise,
-you may see errors at runtime like: <code>A is not a subtype of A</code>, which can be
-extremely confusing.</p>
-<p>When you follow the rules above, our tools can detect the pattern in the
-HTML-import URL containing <code>packages/</code> and canonicalize the import
-by converting <code>packages/a/a.dart</code> into <code>package:a/a.dart</code> under the hood.</p></li><li>
-<p>They need to continue to be valid after applications are built.
-Technically this could be done automatically with pub transformers, but to
-make sure that code works also in Dartium with a simple HTTP Server,
-existing transformers do not fix URLs, they just detect inconsistencies and
-produce an error message like this one, instead.</p></li></ul>
+Dart code, but in any other language (like HTML or CSS) use relative URLs that

-A general-purpose serialization facility for Dart Objects.
-
-This provides the ability to save and restore objects to pluggable
-Formats using pluggable Rules.
-These rules can use mirrors or be hard-coded. The main principle
-is using only public APIs on the serialized objects, so changes to the
-internal representation do not break previous serializations. It also handles
-cycles, different representations, filling in known objects on the
-receiving side, and other issues. It is not as much intended for
-APIs using JSON to pass acyclic structures without class information,
-and is fairly heavweight and expensive for doing that compared to simpler
-approaches.

-/**
- * A general-purpose serialization facility for Dart objects.
- *
- * A [Serialization] is defined in terms of [SerializationRule]s and supports
- * reading and writing to different formats.
- *
- * For information on installing and importing this library, see the
- * [serialization package on pub.dartlang.org]
- * (http://pub.dartlang.org/packages/serialization).
- *
- * ## Setup
- *
- * A simple example of usage is
- *
- * var address = new Address();
- * address.street = 'N 34th';
- * address.city = 'Seattle';
- * var serialization = new Serialization()
- * ..addRuleFor(Address);
- * Map output = serialization.write(address);
- *
- * This creates a new serialization and adds a rule for address objects.
- * Then we ask the [Serialization] to write the address
- * and we get back a Map which is a [json]able representation of the state of
- * the address and related objects. Note that while the output in this case
- * is a [Map], the type will vary depending on which output format we've told
- * the [Serialization] to use.
- *
- * The version above used reflection to automatically identify the public
- * fields of the address object. We can also specify those fields explicitly.
- *
- * var serialization = new Serialization()
- * ..addRuleFor(Address,
- * constructor: "create",
- * constructorFields: ["number", "street"],
- * fields: ["city"]);
- *
- * This rule still uses reflection to access the fields, but does not try to
- * identify which fields to use, but instead uses only the "number" and "street"
- * fields that we specified. We may also want to tell it to identify the
- * fields, but to specifically omit certain fields that we don't want
- * serialized.
- *
- * var serialization = new Serialization()
- * ..addRuleFor(Address,
- * constructor: "",
- * excludeFields: ["other", "stuff"]);
- *
- * ## Writing rules
- *
- * We can also use a completely non-reflective rule to serialize and
- * de-serialize objects. This can be more work, but it does work in
- * dart2js, where mirrors are not yet implemented. We can specify this in two
- * ways. First, we can write our own SerializationRule class that has methods
- * for our Address class.
- *
- * class AddressRule extends CustomRule {
- * bool appliesTo(instance, Writer w) => instance.runtimeType == Address;
- * getState(instance) => [instance.street, instance.city];
- * create(state) => new Address();
- * setState(Address a, List state) {
- * a.street = state[0];
- * a.city = state[1];
- * }
- * }
- *
- * The class needs four different methods. The [CustomRule.appliesTo]
- * method tells us if
- * the rule should be used to write an object. In this example we use a test
- * based on runtimeType. We could also use an "is Address" test, but if Address
- * has subclasses that would find those as well, and we want a separate rule
- * for each. The [CustomRule.getState] method should
- * return all the state of the object that we want to recreate,
- * and should be either a Map or a List. If you want to write to human-readable
- * formats where it's useful to be able to look at the data as a map from
- * field names to values, then it's better to return it as a map. Otherwise it's
- * more efficient to return it as a list. You just need to be sure that the
- * [CustomRule.create] and [CustomRule.setState] methods interpret the data the
- * same way as [CustomRule.getState] does.
- *
- * The [CustomRule.create] method will create the new object and return it. While it's
- * possible to create the object and set all its state in this one method, that
- * increases the likelihood of problems with cycles. So it's better to use the
- * minimum necessary information in [CustomRule.create] and do more of the work
- * in [CustomRule.setState].
- *
- * The other way to do this is not creating a subclass, but by using a
- * [ClosureRule] and giving it functions for how to create
- * the address.
- *
- * addressToMap(a) => {"number" : a.number, "street" : a.street,
- * "city" : a.city};
- * createAddress(Map m) => new Address.create(m["number"], m["street"]);
- * fillInAddress(Address a, Map m) => a.city = m["city"];
- * var serialization = new Serialization()
- * ..addRule(
- * new ClosureRule(anAddress.runtimeType,
- * addressToMap, createAddress, fillInAddress);
- *
- * In this case we have created standalone functions rather than
- * methods in a subclass and we pass them to the constructor of
- * [ClosureRule]. In this case we've also had them use maps rather than
- * lists for the state, but either would work as long as the rule is
- * consistent with the representation it uses. We pass it the runtimeType
- * of the object, and functions equivalent to the methods on [CustomRule]
- *
- * ## Constant values
- *
- * There are cases where the constructor needs values that we can't easily get
- * from the serialized object. For example, we may just want to pass null, or a
- * constant value. To support this, we can specify as constructor fields
- * values that aren't field names. If any value isn't a String, or is a string
- * that doesn't correspond to a field name, it will be
- * treated as a constant and passed unaltered to the constructor.
- *
- * In some cases a non-constructor field should not be set using field
- * access or a setter, but should be done by calling a method. For example, it
- * may not be possible to set a List field "foo", and you need to call an
- * addFoo() method for each entry in the list. In these cases, if you are using
- * a BasicRule for the object you can call the setFieldWith() method.
- *
- * s..addRuleFor(FooHolder).setFieldWith("foo",
- * (parent, value) => for (var each in value) parent.addFoo(value));
- *
- * ## Writing
- *
- * To write objects, we use the write() method.
- *
- * var output = serialization.write(someObject);
- *
- * By default this uses a representation in which objects are represented as
- * maps keyed by field name, but in which references between objects have been
- * converted into Reference objects. This is then typically encoded as
- * a [json] string, but can also be used in other ways, e.g. sent to another
- * isolate.
- *
- * We can write objects in different formats by passing a [Format] object to
- * the [Serialization.write] method or by getting a [Writer] object.
- * The available formats
- * include the default, a simple "flat" format that doesn't include field names,
- * and a simple JSON format that produces output more suitable for talking to
- * services that expect JSON in a predefined format. Examples of these are
- *
- * Map output = serialization.write(address, new SimpleMapFormat());
- * List output = serialization.write(address, new SimpleFlatFormat());
- * var output = serialization.write(address, new SimpleJsonFormat());
- * Or, using a [Writer] explicitly
- * var writer = serialization.newWriter(new SimpleFlatFormat());
- * List output = writer.write(address);
- *
- * These representations are not yet considered stable.
- *
- * ## Reading
- *
- * To read objects, the corresponding [Serialization.read] method can be used.
- *
- * Address input = serialization.read(input);
- *
- * When reading, the serialization instance doing the reading must be configured
- * with compatible rules to the one doing the writing. It's possible for the
- * rules to be different, but they need to be able to read the same
- * representation. For most practical purposes right now they should be the
- * same. The simplest way to achieve this is by having the serialization
- * variable [Serialization.selfDescribing] be true. In that case the rules
- * themselves are also
- * stored along with the serialized data, and can be read back on the receiving
- * end. Note that this may not work for all rules or all formats. The
- * [Serialization.selfDescribing] variable is true by default, but the
- * [SimpleJsonFormat] does not support it, since the point is to provide a
- * representation in a form
- * other services might expect. Using CustomRule or ClosureRule also does not
- * yet work with the [Serialization.selfDescribing] variable.
- *
- * ## Named objects
- *
- * When reading, some object references should not be serialized, but should be
- * connected up to other instances on the receiving side. A notable example of
- * this is when serialization rules have been stored. Instances of BasicRule
- * take a [ClassMirror] in their constructor, and we cannot serialize those. So
- * when we read the rules, we must provide a Map<String, Object> which maps from
- * the simple name of classes we are interested in to a [ClassMirror]. This can
- * be provided either in the [Serialization.namedObjects],
- * or as an additional parameter to the reading and writing methods on the
- * [Reader] or [Writer] respectively.
- *
- * new Serialization()
- * ..addRuleFor(Person, constructorFields: ["name"])
- * ..namedObjects['Person'] = reflect(new Person()).type;

The goal is to allow users to avoid the \n most obvious pitfalls and do so without compromising performance significantly. \n For ShadowDOM styling that's not covered here, a set of best practices\n can be provided that should allow users to accomplish more complex styling.\n\n The following is a list of specific ShadowDOM styling features and a brief\n discussion of the approach used to shim.\n\n Shimmed features:\n\n * :host, :host-context: ShadowDOM allows styling of the shadowRoot's host\n element using the :host rule. To shim this feature, the :host styles are \n reformatted and prefixed with a given scope name and promoted to a \n document level stylesheet.\n For example, given a scope name of .foo, a rule like this:\n \n :host {\n background: red;\n }\n }\n \n becomes:\n \n .foo {\n background: red;\n }\n \n * encapsultion: Styles defined within ShadowDOM, apply only to \n dom inside the ShadowDOM. Polymer uses one of two techniques to imlement\n this feature.\n \n By default, rules are prefixed with the host element tag name \n as a descendant selector. This ensures styling does not leak out of the 'top'\n of the element's ShadowDOM. For example,\n\n div {\n font-weight: bold;\n }\n \n becomes:\n\n x-foo div {\n font-weight: bold;\n }\n \n becomes:\n\n\n Alternatively, if Platform.ShadowCSS.strictStyling is set to true then \n selectors are scoped by adding an attribute selector suffix to each\n simple selector that contains the host element tag name. Each element \n in the element's ShadowDOM template is also given the scope attribute. \n Thus, these rules match only elements that have the scope attribute.\n For example, given a scope name of x-foo, a rule like this:\n \n div {\n font-weight: bold;\n }\n \n becomes:\n \n div[x-foo] {\n font-weight: bold;\n }\n\n Note that elements that are dynamically added to a scope must have the scope\n selector added to them manually.\n\n * upper/lower bound encapsulation: Styles which are defined outside a\n shadowRoot should not cross the ShadowDOM boundary and should not apply\n inside a shadowRoot.\n\n This styling behavior is not emulated. Some possible ways to do this that \n were rejected due to complexity and/or performance concerns include: (1) reset\n every possible property for every possible selector for a given scope name;\n (2) re-implement css in javascript.\n \n As an alternative, users should make sure to use selectors\n specific to the scope in which they are working.\n \n * ::distributed: This behavior is not emulated. It's often not necessary\n to style the contents of a specific insertion point and instead, descendants\n of the host element can be styled selectively. Users can also create an \n extra node around an insertion point and style that node's contents\n via descendent selectors. For example, with a shadowRoot like this:\n \n <style>\n ::content(div) {\n background: red;\n }\n </style>\n <content></content>\n \n could become:\n \n <style>\n / *@polyfill .content-container div * / \n ::content(div) {\n background: red;\n }\n </style>\n <div class=\"content-container\">\n <content></content>\n </div>\n \n Note the use of @polyfill in the comment above a ShadowDOM specific style\n declaration. This is a directive to the styling shim to use the selector \n in comments in lieu of the next selector when running under polyfill.\n*/\n(function(scope) {\n\nvar ShadowCSS = {\n strictStyling: false,\n registry: {},\n // Shim styles for a given root associated with a name and extendsName\n // 1. cache root styles by name\n // 2. optionally tag root nodes with scope name\n // 3. shim polyfill directives /* @polyfill */ and /* @polyfill-rule */\n // 4. shim :host and scoping\n shimStyling: function(root, name, extendsName) {\n var scopeStyles = this.prepareRoot(root, name, extendsName);\n var typeExtension = this.isTypeExtension(extendsName);\n var scopeSelector = this.makeScopeSelector(name, typeExtension);\n // use caching to make working with styles nodes easier and to facilitate\n // lookup of extendee\n var cssText = stylesToCssText(scopeStyles, true);\n cssText = this.scopeCssText(cssText, scopeSelector);\n // cache shimmed css on root for user extensibility\n if (root) {\n root.shimmedStyle = cssText;\n }\n // add style to document\n this.addCssToDocument(cssText, name);\n },\n /*\n * Shim a style element with the given selector.

The goal is to allow users to avoid the \n most obvious pitfalls and do so without compromising performance significantly. \n For ShadowDOM styling that's not covered here, a set of best practices\n can be provided that should allow users to accomplish more complex styling.\n\n The following is a list of specific ShadowDOM styling features and a brief\n discussion of the approach used to shim.\n\n Shimmed features:\n\n * :host, :host-context: ShadowDOM allows styling of the shadowRoot's host\n element using the :host rule. To shim this feature, the :host styles are \n reformatted and prefixed with a given scope name and promoted to a \n document level stylesheet.\n For example, given a scope name of .foo, a rule like this:\n \n :host {\n background: red;\n }\n }\n \n becomes:\n \n .foo {\n background: red;\n }\n \n * encapsultion: Styles defined within ShadowDOM, apply only to \n dom inside the ShadowDOM. Polymer uses one of two techniques to imlement\n this feature.\n \n By default, rules are prefixed with the host element tag name \n as a descendant selector. This ensures styling does not leak out of the 'top'\n of the element's ShadowDOM. For example,\n\n div {\n font-weight: bold;\n }\n \n becomes:\n\n x-foo div {\n font-weight: bold;\n }\n \n becomes:\n\n\n Alternatively, if Platform.ShadowCSS.strictStyling is set to true then \n selectors are scoped by adding an attribute selector suffix to each\n simple selector that contains the host element tag name. Each element \n in the element's ShadowDOM template is also given the scope attribute. \n Thus, these rules match only elements that have the scope attribute.\n For example, given a scope name of x-foo, a rule like this:\n \n div {\n font-weight: bold;\n }\n \n becomes:\n \n div[x-foo] {\n font-weight: bold;\n }\n\n Note that elements that are dynamically added to a scope must have the scope\n selector added to them manually.\n\n * upper/lower bound encapsulation: Styles which are defined outside a\n shadowRoot should not cross the ShadowDOM boundary and should not apply\n inside a shadowRoot.\n\n This styling behavior is not emulated. Some possible ways to do this that \n were rejected due to complexity and/or performance concerns include: (1) reset\n every possible property for every possible selector for a given scope name;\n (2) re-implement css in javascript.\n \n As an alternative, users should make sure to use selectors\n specific to the scope in which they are working.\n \n * ::distributed: This behavior is not emulated. It's often not necessary\n to style the contents of a specific insertion point and instead, descendants\n of the host element can be styled selectively. Users can also create an \n extra node around an insertion point and style that node's contents\n via descendent selectors. For example, with a shadowRoot like this:\n \n <style>\n ::content(div) {\n background: red;\n }\n </style>\n <content></content>\n \n could become:\n \n <style>\n / *@polyfill .content-container div * / \n ::content(div) {\n background: red;\n }\n </style>\n <div class=\"content-container\">\n <content></content>\n </div>\n \n Note the use of @polyfill in the comment above a ShadowDOM specific style\n declaration. This is a directive to the styling shim to use the selector \n in comments in lieu of the next selector when running under polyfill.\n*/\n(function(scope) {\n\nvar ShadowCSS = {\n strictStyling: false,\n registry: {},\n // Shim styles for a given root associated with a name and extendsName\n // 1. cache root styles by name\n // 2. optionally tag root nodes with scope name\n // 3. shim polyfill directives /* @polyfill */ and /* @polyfill-rule */\n // 4. shim :host and scoping\n shimStyling: function(root, name, extendsName) {\n var scopeStyles = this.prepareRoot(root, name, extendsName);\n var typeExtension = this.isTypeExtension(extendsName);\n var scopeSelector = this.makeScopeSelector(name, typeExtension);\n // use caching to make working with styles nodes easier and to facilitate\n // lookup of extendee\n var cssText = stylesToCssText(scopeStyles, true);\n cssText = this.scopeCssText(cssText, scopeSelector);\n // cache shimmed css on root for user extensibility\n if (root) {\n root.shimmedStyle = cssText;\n }\n // add style to document\n this.addCssToDocument(cssText, name);\n },\n /*\n * Shim a style element with the given selector.

The goal is to allow users to avoid the \n most obvious pitfalls and do so without compromising performance significantly. \n For ShadowDOM styling that's not covered here, a set of best practices\n can be provided that should allow users to accomplish more complex styling.\n\n The following is a list of specific ShadowDOM styling features and a brief\n discussion of the approach used to shim.\n\n Shimmed features:\n\n * :host, :host-context: ShadowDOM allows styling of the shadowRoot's host\n element using the :host rule. To shim this feature, the :host styles are \n reformatted and prefixed with a given scope name and promoted to a \n document level stylesheet.\n For example, given a scope name of .foo, a rule like this:\n \n :host {\n background: red;\n }\n }\n \n becomes:\n \n .foo {\n background: red;\n }\n \n * encapsultion: Styles defined within ShadowDOM, apply only to \n dom inside the ShadowDOM. Polymer uses one of two techniques to imlement\n this feature.\n \n By default, rules are prefixed with the host element tag name \n as a descendant selector. This ensures styling does not leak out of the 'top'\n of the element's ShadowDOM. For example,\n\n div {\n font-weight: bold;\n }\n \n becomes:\n\n x-foo div {\n font-weight: bold;\n }\n \n becomes:\n\n\n Alternatively, if Platform.ShadowCSS.strictStyling is set to true then \n selectors are scoped by adding an attribute selector suffix to each\n simple selector that contains the host element tag name. Each element \n in the element's ShadowDOM template is also given the scope attribute. \n Thus, these rules match only elements that have the scope attribute.\n For example, given a scope name of x-foo, a rule like this:\n \n div {\n font-weight: bold;\n }\n \n becomes:\n \n div[x-foo] {\n font-weight: bold;\n }\n\n Note that elements that are dynamically added to a scope must have the scope\n selector added to them manually.\n\n * upper/lower bound encapsulation: Styles which are defined outside a\n shadowRoot should not cross the ShadowDOM boundary and should not apply\n inside a shadowRoot.\n\n This styling behavior is not emulated. Some possible ways to do this that \n were rejected due to complexity and/or performance concerns include: (1) reset\n every possible property for every possible selector for a given scope name;\n (2) re-implement css in javascript.\n \n As an alternative, users should make sure to use selectors\n specific to the scope in which they are working.\n \n * ::distributed: This behavior is not emulated. It's often not necessary\n to style the contents of a specific insertion point and instead, descendants\n of the host element can be styled selectively. Users can also create an \n extra node around an insertion point and style that node's contents\n via descendent selectors. For example, with a shadowRoot like this:\n \n <style>\n ::content(div) {\n background: red;\n }\n </style>\n <content></content>\n \n could become:\n \n <style>\n / *@polyfill .content-container div * / \n ::content(div) {\n background: red;\n }\n </style>\n <div class=\"content-container\">\n <content></content>\n </div>\n \n Note the use of @polyfill in the comment above a ShadowDOM specific style\n declaration. This is a directive to the styling shim to use the selector \n in comments in lieu of the next selector when running under polyfill.\n*/\n(function(scope) {\n\nvar ShadowCSS = {\n strictStyling: false,\n registry: {},\n // Shim styles for a given root associated with a name and extendsName\n // 1. cache root styles by name\n // 2. optionally tag root nodes with scope name\n // 3. shim polyfill directives /* @polyfill */ and /* @polyfill-rule */\n // 4. shim :host and scoping\n shimStyling: function(root, name, extendsName) {\n var scopeStyles = this.prepareRoot(root, name, extendsName);\n var typeExtension = this.isTypeExtension(extendsName);\n var scopeSelector = this.makeScopeSelector(name, typeExtension);\n // use caching to make working with styles nodes easier and to facilitate\n // lookup of extendee\n var cssText = stylesToCssText(scopeStyles, true);\n cssText = this.scopeCssText(cssText, scopeSelector);\n // cache shimmed css on root for user extensibility\n if (root) {\n root.shimmedStyle = cssText;\n }\n // add style to document\n this.addCssToDocument(cssText, name);\n },\n /*\n * Shim a style element with the given selector.
