+# lit-html 2.0
+
+Efficient, Expressive, Extensible HTML templates in JavaScript
+
+[![Build Status](https://github.com/lit/lit/workflows/Tests/badge.svg)](https://github.com/lit/lit/actions?query=workflow%3ATests)
+[![Published on npm](https://img.shields.io/npm/v/lit-html.svg?logo=npm)](https://www.npmjs.com/package/lit-html)
+[![Join our Discord](https://img.shields.io/badge/discord-join%20chat-5865F2.svg?logo=discord&logoColor=fff)](https://lit.dev/discord/)
+[![Mentioned in Awesome Lit](https://awesome.re/mentioned-badge.svg)](https://github.com/web-padawan/awesome-lit)
+
+lit-html is the template system that powers the [Lit](https://lit.dev) library for building fast web components. When using `lit-html` to develop web components, most users should import lit-html via the [`lit`](https://www.npmjs.com/package/lit) package rather than installing and importing from `lit-html` directly.
+
+## About this release
+
+This is a stable release of `lit-html` 2.0 (part of the Lit 2.0 release). If upgrading from previous versions of `lit-html`, please note the minor breaking changes from lit-html 1.0 in the [Upgrade Guide](https://lit.dev/docs/releases/upgrade/).
+
+## Documentation
+
+Full documentation is available at [lit.dev](https://lit.dev).
+
+## Overview
+
+`lit-html` lets you write [HTML templates](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/template) in JavaScript with [template literals](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Template_literals).
+
+lit-html templates are plain JavaScript and combine the familiarity of writing HTML with the power of JavaScript. lit-html takes care of efficiently rendering templates to DOM, including efficiently updating the DOM with new values.
+
+```javascript
+import {html, render} from 'lit-html';
+
+// This is a lit-html template function. It returns a lit-html template.
+const helloTemplate = (name) => html`<div>Hello ${name}!</div>`;
+
+// This renders <div>Hello Steve!</div> to the document body
+render(helloTemplate('Steve'), document.body);
+
+// This updates to <div>Hello Kevin!</div>, but only updates the ${name} part
+render(helloTemplate('Kevin'), document.body);
+```
+
+`lit-html` provides two main exports:
+
+- `html`: A JavaScript [template tag](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Template_literals#Tagged_template_literals) used to produce a `TemplateResult`, which is a container for a template, and the values that should populate the template.
+- `render()`: A function that renders a `TemplateResult` to a DOM container, such as an element or shadow root.
+
+## Installation
+
+```bash
+$ npm install lit-html
+```
+
+Or use from `lit`:
+
+```bash
+$ npm install lit
+```

+/**
+ * Overview:
+ *
+ * This module is designed to add support for an async `setValue` API and
+ * `disconnected` callback to directives with the least impact on the core
+ * runtime or payload when that feature is not used.
+ *
+ * The strategy is to introduce a `AsyncDirective` subclass of
+ * `Directive` that climbs the "parent" tree in its constructor to note which
+ * branches of lit-html's "logical tree" of data structures contain such
+ * directives and thus need to be crawled when a subtree is being cleared (or
+ * manually disconnected) in order to run the `disconnected` callback.
+ *
+ * The "nodes" of the logical tree include Parts, TemplateInstances (for when a
+ * TemplateResult is committed to a value of a ChildPart), and Directives; these
+ * all implement a common interface called `DisconnectableChild`. Each has a
+ * `_$parent` reference which is set during construction in the core code, and a
+ * `_$disconnectableChildren` field which is initially undefined.
+ *
+ * The sparse tree created by means of the `AsyncDirective` constructor
+ * crawling up the `_$parent` tree and placing a `_$disconnectableChildren` Set
+ * on each parent that includes each child that contains a
+ * `AsyncDirective` directly or transitively via its children. In order to
+ * notify connection state changes and disconnect (or reconnect) a tree, the
+ * `_$notifyConnectionChanged` API is patched onto ChildParts as a directive
+ * climbs the parent tree, which is called by the core when clearing a part if
+ * it exists. When called, that method iterates over the sparse tree of
+ * Set<DisconnectableChildren> built up by AsyncDirectives, and calls
+ * `_$notifyDirectiveConnectionChanged` on any directives that are encountered
+ * in that tree, running the required callbacks.
+ *
+ * A given "logical tree" of lit-html data-structures might look like this:
+ *
+ *  ChildPart(N1) _$dC=[D2,T3]
+ *   ._directive
+ *     AsyncDirective(D2)
+ *   ._value // user value was TemplateResult
+ *     TemplateInstance(T3) _$dC=[A4,A6,N10,N12]
+ *      ._$parts[]

+ *           AsyncDirective(D13)

+ *             ChildPart(N14) _$dC=[D15]

+ *                    ._directives[]
+ *                      AsyncDirective(D22)
+ *                      Directive(D23) _$dC=[D24]

+ * ChildPart will _clear() itself, and so we need to disconnect the "value" of
+ * the ChildPart (but not its directive). In this case, when `_clear()` calls
+ * `_$notifyConnectionChanged()`, we don't iterate all of the
+ * _$disconnectableChildren, rather we do a value-specific disconnection: i.e.
+ * since the _value was an Array<ChildPart> (because an iterable had been
+ * committed), we iterate the array of ChildParts (N14, N16) and run
+ * `setConnected` on them (which does recurse down the full tree of
+ * `_$disconnectableChildren` below it, and also removes N14 and N16 from N12's
+ * `_$disconnectableChildren`). Once the values have been disconnected, we then
+ * check whether the ChildPart(N12)'s list of `_$disconnectableChildren` is empty
+ * (and would remove it from its parent TemplateInstance(T3) if so), but since
+ * it would still contain its directive D13, it stays in the disconnectable
+ * tree.
+ *
+ * Example 2: In the course of Example 1, `setConnected` will reach
+ * ChildPart(N16); in this case the entire part is being disconnected, so we
+ * simply iterate all of N16's `_$disconnectableChildren` (D17,T18) and
+ * recursively run `setConnected` on them. Note that we only remove children
+ * from `_$disconnectableChildren` for the top-level values being disconnected
+ * on a clear; doing this bookkeeping lower in the tree is wasteful since it's
+ * all being thrown away.
+ *
+ * Example 3: If the LitElement containing the entire tree above becomes
+ * disconnected, it will run `childPart.setConnected()` (which calls
+ * `childPart._$notifyConnectionChanged()` if it exists); in this case, we
+ * recursively run `setConnected()` over the entire tree, without removing any
+ * children from `_$disconnectableChildren`, since this tree is required to
+ * re-connect the tree, which does the same operation, simply passing
+ * `isConnected: true` down the tree, signaling which callback to run.

+ * A directive that repeats a series of values (usually `TemplateResults`)
+ * generated from an iterable, and updates those items efficiently when the
+ * iterable changes based on user-provided `keys` associated with each item.
+ *
+ * Note that if a `keyFn` is provided, strict key-to-DOM mapping is maintained,
+ * meaning previous DOM for a given key is moved into the new position if
+ * needed, and DOM will never be reused with values for different keys (new DOM
+ * will always be created for new keys). This is generally the most efficient
+ * way to use `repeat` since it performs minimum unnecessary work for insertions
+ * and removals.
+ *
+ * The `keyFn` takes two parameters, the item and its index, and returns a unique key value.
+ *
+ * ```js
+ * html`
+ *   <ol>
+ *     ${repeat(this.items, (item) => item.id, (item, index) => {
+ *       return html`<li>${index}: ${item.name}</li>`;
+ *     })}
+ *   </ol>
+ * `
+ * ```
+ *
+ * **Important**: If providing a `keyFn`, keys *must* be unique for all items in a
+ * given call to `repeat`. The behavior when two or more items have the same key
+ * is undefined.
+ *
+ * If no `keyFn` is provided, this directive will perform similar to mapping
+ * items to values, and DOM will be reused against potentially different items.

+        //   from either end and pass each other before we get to this
+        //   case and removals would be handled in the final while loop
+        //   without needing to generate the map.
+        //
+        // * Example below: The key at `oldTail` was removed (no longer
+        //   in the `newKeyToIndexMap`), so remove that part from the
+        //   DOM and advance just the `oldTail` pointer.

+        //         newHead ^           ^ newTail
+        //
+        // * Once head and tail cannot move, any mismatches are due to
+        //   either new or moved items; if a new key is in the previous
+        //   "old key to old index" map, move the old part to the new
+        //   location, otherwise create and insert a new part. Note
+        //   that when moving an old part we null its position in the
+        //   oldParts array if it lies between the head and tail so we
+        //   know to skip it when the pointers get there.
+        //
+        // * Example below: neither head nor tail match, and neither
+        //   were removed; so find the `newHead` key in the
+        //   `oldKeyToIndexMap`, and move that old part's DOM into the
+        //   next head position (before `oldParts[oldHead]`). Last,
+        //   null the part in the `oldPart` array since it was
+        //   somewhere in the remaining oldParts still to be scanned
+        //   (between the head and tail pointers) so that we know to
+        //   skip that old part on future iterations.
+        //
+        //         oldHead v        v oldTail
+        //   oldKeys:  [0, 1, -, 3, 4, 5, 6]
+        //   newParts: [0, 2,  ,  ,  ,  , 6] <- stuck: update & move 2
+        //   newKeys:  [0, 2, 1, 4, 3, 7, 6]    into place and advance

+        //         newHead ^           ^ newTail
+        //
+        // * Note that for moves/insertions like the one above, a part
+        //   inserted at the head pointer is inserted before the
+        //   current `oldParts[oldHead]`, and a part inserted at the
+        //   tail pointer is inserted before `newParts[newTail+1]`. The
+        //   seeming asymmetry lies in the fact that new parts are
+        //   moved into place outside in, so to the right of the head
+        //   pointer are old parts, and to the right of the tail
+        //   pointer are new parts.
+        //
+        // * We always restart back from the top of the algorithm,
+        //   allowing matching and simple updates in place to
+        //   continue...
+        //
+        // * Example below: the head pointers once again match, so
+        //   simply update part 1 and record it in the `newParts`
+        //   array.  Last, advance both head pointers.
+        //
+        //         oldHead v        v oldTail
+        //   oldKeys:  [0, 1, -, 3, 4, 5, 6]
+        //   newParts: [0, 2, 1,  ,  ,  , 6] <- heads matched: update 1
+        //   newKeys:  [0, 2, 1, 4, 3, 7, 6]    and advance both oldHead
+        //                                      & newHead
+        //            newHead ^        ^ newTail
+        //
+        // * As mentioned above, items that were moved as a result of
+        //   being stuck (the final else clause in the code below) are
+        //   marked with null, so we always advance old pointers over
+        //   these so we're comparing the next actual old value on
+        //   either end.
+        //
+        // * Example below: `oldHead` is null (already placed in

+        //   important to the algorithm, as long as the null checks
+        //   come first (to ensure we're always working on valid old
+        //   parts) and that the final else clause comes last (since

+        //   moves of contiguous items in linear time, in the minimum
+        //   number of moves. As the number of multiple moves where LIS

+/**
+ * A directive that repeats a series of values (usually `TemplateResults`)
+ * generated from an iterable, and updates those items efficiently when the
+ * iterable changes based on user-provided `keys` associated with each item.
+ *
+ * Note that if a `keyFn` is provided, strict key-to-DOM mapping is maintained,
+ * meaning previous DOM for a given key is moved into the new position if
+ * needed, and DOM will never be reused with values for different keys (new DOM
+ * will always be created for new keys). This is generally the most efficient
+ * way to use `repeat` since it performs minimum unnecessary work for insertions
+ * and removals.
+ *
+ * The `keyFn` takes two parameters, the item and its index, and returns a unique key value.
+ *
+ * ```js
+ * html`
+ *   <ol>
+ *     ${repeat(this.items, (item) => item.id, (item, index) => {
+ *       return html`<li>${index}: ${item.name}</li>`;
+ *     })}
+ *   </ol>
+ * `
+ * ```
+ *
+ * **Important**: If providing a `keyFn`, keys *must* be unique for all items in a
+ * given call to `repeat`. The behavior when two or more items have the same key
+ * is undefined.
+ *
+ * If no `keyFn` is provided, this directive will perform similar to mapping
+ * items to values, and DOM will be reused against potentially different items.

+/**
+ * Renders one of a series of values, including Promises, to a Part.
+ *
+ * Values are rendered in priority order, with the first argument having the
+ * highest priority and the last argument having the lowest priority. If a
+ * value is a Promise, low-priority values will be rendered until it resolves.
+ *
+ * The priority of values can be used to create placeholder content for async
+ * data. For example, a Promise with pending content can be the first,
+ * highest-priority, argument, and a non_promise loading indicator template can
+ * be used as the second, lower-priority, argument. The loading indicator will
+ * render immediately, and the primary content will render when the Promise
+ * resolves.
+ *
+ * Example:
+ *
+ * ```js
+ * const content = fetch('./content.txt').then(r => r.text());
+ * html`${until(content, html`<span>Loading...</span>`)}`
+ * ```
