+# amap-jsapi-loader
+amap-jsapi-loader 是高德开放平台官网提供的地图 JSAPI 的加载器，可帮助开发者快速定位、有效避免加载引用地图 JSAPI 各种错误用法。
+
+
+该加载器具有以下特性：
+* 支持以 普通JS 和 npm包 两种方式使用；
+* 有效避免错误异步加载导致的 JSAPI 资源加载不完整问题；
+* 对于加载混用多个版本 JSAPI 的错误用法给予报错处理；
+* 对于不合法加载引用 JSAPI 给予报错处理；
+* 支持指定 JSAPI 版本；
+* 支持插件加载；
+* 允许多次执行加载操作，网络资源不会重复请求，便于大型工程模块管理；
+
+
+# USAGE
+
+## AMapLoader.load方法参数说明
+```js
+AMapLoader.load({
+    "key": "",              // 申请好的Web端开发者Key，首次调用 load 时必填
+    "version": "2.0",   // 指定要加载的 JSAPI 的版本，缺省时默认为 1.4.15
+    "plugins": []           // 需要使用的的插件列表，如比例尺'AMap.Scale'等
+    "AMapUI": {             // 是否加载 AMapUI，缺省不加载
+        "version": '1.1',   // AMapUI 缺省 1.1
+        "plugins":[],       // 需要加载的 AMapUI ui插件
+    },
+    "Loca":{                // 是否加载 Loca， 缺省不加载
+        "version": '1.3.2'  // Loca 版本，缺省 1.3.2
+    },
+}).then(()=>{
+    window.AMap.xx;
+    window.AMapUI.xx;
+    window.Loca.xx
+});
+
+```
+
+## AMapUI
+
+AMapUI 用法和官网有一点点区别。通过 AMapUI.xx 来获取组件
+```js
+AMapLoader.load({
+    key: '',//首次load必填
+    version: '2.0',
+    AMapUI: {
+        version: '1.1',
+        plugins: ['overlay/SimpleMarker'],
+    }
+}).then((AMap) => {
+    map = new AMap.Map('container');
+
+    // !!! 通过 AMap.SimpleMarker 获取组件
+    new AMapUI.SimpleMarker({
+        //前景文字
+        iconLabel: 'A',
+        //图标主题
+        iconTheme: 'default',
+        //背景图标样式
+        iconStyle: 'red',
+        map: map,
+        position: map.getCenter()
+    });
+}).catch((e) => {
+    console.error(e);
+});
+```
+
+
+# 使用
+#### 以普通 JS 方式使用 Loader
+尚未发布在线Loader，可将 dist/index.js 复制到项目下
+```
+<script src="../dist/index.js"></script>
+<script>
+    AMapLoader.load({
+        key:'',//首次load必填
+        version:'2.0',
+        plugins:['AMap.Scale']
+    }).then((AMap)=>{
+        map = new AMap.Map('container');
+        map.addControl(new AMap.Scale())
+    }).catch((e)=>{
+        console.error(e);
+    });   
+</script>
+```
+#### 以 NPM 包方式使用 Loader
+安装
+```
+tnpm i @alife/amap-jsapi-loader --save-dev
+```
+使用
+```
+import AMapLoader from '@alife/amap-jsapi-loader';
+
+AMapLoader.load().then((AMap)=>{
+    map = new AMap.Map('container');
+}).catch(e=>{
+    console.log(e);
+})
+

+## API
+
+### ansiRegex([options])
+
+Returns a regex for matching ANSI escape codes.
+
+#### options
+
+##### onlyFirst
+
+Type: `boolean`<br>
+Default: `false` *(Matches any ANSI escape codes in a string)*
+
+Match only the first ANSI escape.
+
+
+## FAQ
+
+### Why do you test for codes not in the ECMA 48 standard?
+
+Some of the codes we run as a test are codes that we acquired finding various lists of non-standard or manufacturer specific codes. We test for both standard and non-standard codes, as most of them follow the same or similar format and can be safely matched in strings without the risk of removing actual string content. There are a few non-standard control codes that do not follow the traditional format (i.e. they end in numbers) thus forcing us to exclude them from the test because we cannot reliably match them.
+
+On the historical side, those ECMA standards were established in the early 90's whereas the VT100, for example, was designed in the mid/late 70's. At that point in time, control codes were still pretty ungoverned and engineers used them for a multitude of things, namely to activate hardware ports that may have been proprietary. Somewhere else you see a similar 'anarchy' of codes is in the x86 architecture for processors; there are a ton of "interrupts" that can mean different things on certain brands of processors, most of which have been phased out.

+// NOTE: If conversion goes to 16 colors or 256 colors, the original color
+//       may be degraded to fit that color palette. This means terminals
+//       that do not support 16 million colors will best-match the

+console.log(style.color.ansi16m.hex('#ABCDEF') + 'Hello world!' + style.color.close);
+```
+
+## API
+
+Each style has an `open` and `close` property.
+
+
+## Styles

+
+## Advanced usage
+
+By default, you get a map of styles, but the styles are also available as groups. They are non-enumerable so they don't show up unless you access them explicitly. This makes it easier to expose only a subset in a higher-level module.
+
+- `style.modifier`
+- `style.color`
+- `style.bgColor`
+
+###### Example
+
+```js
+console.log(style.color.green.open);
+```
+
+Raw escape codes (i.e. without the CSI escape prefix `\u001B[` and render mode postfix `m`) are available under `style.codes`, which returns a `Map` with the open codes as keys and close codes as values.
+
+###### Example
+
+```js
+console.log(style.codes.get(36));
+//=> 39
+```
+
+
+## [256 / 16 million (TrueColor) support](https://gist.github.com/XVilka/8346728)
+
+`ansi-styles` uses the [`color-convert`](https://github.com/Qix-/color-convert) package to allow for converting between various colors and ANSI escapes, with support for 256 and 16 million colors.
+
+To use these, call the associated conversion function with the intended output, for example:
+
+```js
+style.color.ansi.rgb(100, 200, 15); // RGB to 16 color ansi foreground code
+style.bgColor.ansi.rgb(100, 200, 15); // RGB to 16 color ansi background code
+
+style.color.ansi256.hsl(120, 100, 60); // HSL to 256 color ansi foreground code
+style.bgColor.ansi256.hsl(120, 100, 60); // HSL to 256 color ansi foreground code
+
+style.color.ansi16m.hex('#C0FFEE'); // Hex (RGB) to 16 million color foreground code
+style.bgColor.ansi16m.hex('#C0FFEE'); // Hex (RGB) to 16 million color background code
+```

+base64-js
+=========
+
+`base64-js` does basic base64 encoding/decoding in pure JS.
+
+[![build status](https://secure.travis-ci.org/beatgammit/base64-js.png)](http://travis-ci.org/beatgammit/base64-js)
+
+Many browsers already have base64 encoding/decoding functionality, but it is for text data, not all-purpose binary data.
+
+Sometimes encoding/decoding binary data in the browser is useful, and that is what this module does.
+
+## install
+
+With [npm](https://npmjs.org) do:
+
+`npm install base64-js` and `var base64js = require('base64-js')`
+
+For use in web browsers do:
+
+`<script src="base64js.min.js"></script>`
+
+## methods
+
+`base64js` has three exposed functions, `byteLength`, `toByteArray` and `fromByteArray`, which both take a single argument.
+
+* `byteLength` - Takes a base64 string and returns length of byte array
+* `toByteArray` - Takes a base64 string and returns a byte array
+* `fromByteArray` - Takes a byte array and returns a base64 string

+# Buffer Fill
+
+A [ponyfill](https://ponyfill.com) for `Buffer.fill`.
+
+Works as Node.js: `v6.4.0` <br>
+Works on Node.js: `v0.10.0`
+
+## Installation
+
+```sh
+npm install --save buffer-fill
+```
+
+## Usage
+
+```js
+const fill = require('buffer-fill')
+const buf = Buffer.allocUnsafe(5)
+
+console.log(buf.fill(8))
+//=> <Buffer 08 08 08 08 08>
+
+console.log(buf.fill(9, 2, 4))
+//=> <Buffer 08 08 09 09 08>
+
+console.log(buf.fill('linus', 'latin1'))
+//=> <Buffer 6c 69 6e 75 73>
+
+console.log(buf.fill('\u0222'))
+//=> <Buffer c8 a2 c8 a2 c8>
+```
+
+## API
+
+### fill(buf, value[, offset[, end]][, encoding])
+
+- `value` &lt;String&gt; | &lt;Buffer&gt; | &lt;Integer&gt; The value to fill `buf` with
+- `offset` &lt;Integer&gt; Where to start filling `buf`. **Default:** `0`
+- `end` &lt;Integer&gt; Where to stop filling `buf` (not inclusive). **Default:** `buf.length`
+- `encoding` &lt;String&gt; If `value` is a string, this is its encoding. **Default:** `'utf8'`
+- Return: &lt;Buffer&gt; A reference to `buf`
+
+Fills `buf` with the specified `value`. If the `offset` and `end` are not given,
+the entire `buf` will be filled. This is meant to be a small simplification to
+allow the creation and filling of a `Buffer` to be done on a single line.
+
+If the final write of a `fill()` operation falls on a multi-byte character, then
+only the first bytes of that character that fit into `buf` are written.

+# Buffer From
+
+A [ponyfill](https://ponyfill.com) for `Buffer.from`, uses native implementation if available.
+
+## Installation
+
+```sh
+npm install --save buffer-from
+```
+
+## Usage
+
+```js
+const bufferFrom = require('buffer-from')
+
+console.log(bufferFrom([1, 2, 3, 4]))
+//=> <Buffer 01 02 03 04>
+
+const arr = new Uint8Array([1, 2, 3, 4])

+
+## API
+
+### bufferFrom(array)
+
+- `array` &lt;Array&gt;
+
+Allocates a new `Buffer` using an `array` of octets.
+
+### bufferFrom(arrayBuffer[, byteOffset[, length]])
+
+- `arrayBuffer` &lt;ArrayBuffer&gt; The `.buffer` property of a TypedArray or ArrayBuffer
+- `byteOffset` &lt;Integer&gt; Where to start copying from `arrayBuffer`. **Default:** `0`
+- `length` &lt;Integer&gt; How many bytes to copy from `arrayBuffer`. **Default:** `arrayBuffer.length - byteOffset`
+
+When passed a reference to the `.buffer` property of a TypedArray instance, the
+newly created `Buffer` will share the same allocated memory as the TypedArray.
+
+The optional `byteOffset` and `length` arguments specify a memory range within
+the `arrayBuffer` that will be shared by the `Buffer`.
+
+### bufferFrom(buffer)
+
+- `buffer` &lt;Buffer&gt; An existing `Buffer` to copy data from
+
+Copies the passed `buffer` data onto a new `Buffer` instance.
+
+### bufferFrom(string[, encoding])
+
+- `string` &lt;String&gt; A string to encode.
+- `encoding` &lt;String&gt; The encoding of `string`. **Default:** `'utf8'`
+
+Creates a new `Buffer` containing the given JavaScript string `string`. If
+provided, the `encoding` parameter identifies the character encoding of
+`string`.

+[saucelabs-url]: https://saucelabs.com/u/buffer
+
+With [browserify](http://browserify.org), simply `require('buffer')` or use the `Buffer` global and you will get this module.
+
+The goal is to provide an API that is 100% identical to
+[node's Buffer API](https://nodejs.org/api/buffer.html). Read the
+[official docs](https://nodejs.org/api/buffer.html) for the full list of properties,
+instance methods, and class methods that are supported.
+
+## features
+
+- Manipulate binary data like a boss, in all browsers!
+- Super fast. Backed by Typed Arrays (`Uint8Array`/`ArrayBuffer`, not `Object`)
+- Extremely small bundle size (**6.75KB minified + gzipped**, 51.9KB with comments)
+- Excellent browser support (Chrome, Firefox, Edge, Safari 9+, IE 11, iOS 9+, Android, etc.)
+- Preserves Node API exactly, with one minor difference (see below)
+- Square-bracket `buf[4]` notation works!
+- Does not modify any browser prototypes or put anything on `window`
+- Comprehensive test suite (including all buffer tests from node.js core)
+
+## `buffer` for enterprise
+
+Available as part of the Tidelift Subscription.
+
+The maintainers of `buffer` and thousands of other packages are working with Tidelift to deliver commercial support and maintenance for the open source dependencies you use to build your applications. Save time, reduce risk, and improve code health, while paying the maintainers of the exact dependencies you use. [Learn more.](https://tidelift.com/subscription/pkg/npm-buffer?utm_source=npm-buffer&utm_medium=referral&utm_campaign=enterprise&utm_term=repo)
+
+## install
+
+To use this module directly (without browserify), install it:
+
+```bash
+npm install buffer
+```
+
+This module was previously called **native-buffer-browserify**, but please use **buffer**
+from now on.
+
+If you do not use a bundler, you can use the [standalone script](https://bundle.run/buffer).
+
+## usage
+
+The module's API is identical to node's `Buffer` API. Read the
+[official docs](https://nodejs.org/api/buffer.html) for the full list of properties,
+instance methods, and class methods that are supported.
+
+As mentioned above, `require('buffer')` or use the `Buffer` global with
+[browserify](http://browserify.org) and this module will automatically be included
+in your bundle. Almost any npm module will work in the browser, even if it assumes that
+the node `Buffer` API will be available.
+
+To depend on this module explicitly (without browserify), require it like this:
+
+```js
+var Buffer = require('buffer/').Buffer  // note: the trailing slash is important!
+```
+
+To require this module explicitly, use `require('buffer/')` which tells the node.js module
+lookup algorithm (also used by browserify) to use the **npm module** named `buffer`
+instead of the **node.js core** module named `buffer`!
+
+
+## how does it work?
+
+The Buffer constructor returns instances of `Uint8Array` that have their prototype
+changed to `Buffer.prototype`. Furthermore, `Buffer` is a subclass of `Uint8Array`,
+so the returned instances will have all the node `Buffer` methods and the
+`Uint8Array` methods. Square bracket notation works as expected -- it returns a
+single octet.
+
+The `Uint8Array` prototype remains unmodified.
+
+
+## tracking the latest node api
+
+This module tracks the Buffer API in the latest (unstable) version of node.js. The Buffer
+API is considered **stable** in the
+[node stability index](https://nodejs.org/docs/latest/api/documentation.html#documentation_stability_index),
+so it is unlikely that there will ever be breaking changes.
+Nonetheless, when/if the Buffer API changes in node, this module's API will change
+accordingly.
+
+## related packages
+
+- [`buffer-reverse`](https://www.npmjs.com/package/buffer-reverse) - Reverse a buffer
+- [`buffer-xor`](https://www.npmjs.com/package/buffer-xor) - Bitwise xor a buffer
+- [`is-buffer`](https://www.npmjs.com/package/is-buffer) - Determine if an object is a Buffer without including the whole `Buffer` package
+
+## conversion packages
+
+### convert typed array to buffer
+
+Use [`typedarray-to-buffer`](https://www.npmjs.com/package/typedarray-to-buffer) to convert any kind of typed array to a `Buffer`. Does not perform a copy, so it's super fast.
+
+### convert buffer to typed array
+
+`Buffer` is a subclass of `Uint8Array` (which is a typed array). So there is no need to explicitly convert to typed array. Just use the buffer as a `Uint8Array`.
+
+### convert blob to buffer
+
+Use [`blob-to-buffer`](https://www.npmjs.com/package/blob-to-buffer) to convert a `Blob` to a `Buffer`.
+
+### convert buffer to blob
+
+To convert a `Buffer` to a `Blob`, use the `Blob` constructor:
+
+```js
+var blob = new Blob([ buffer ])
+```
+
+Optionally, specify a mimetype:
+
+```js
+var blob = new Blob([ buffer ], { type: 'text/html' })
+```
+
+### convert arraybuffer to buffer
+
+To convert an `ArrayBuffer` to a `Buffer`, use the `Buffer.from` function. Does not perform a copy, so it's super fast.
+
+```js
+var buffer = Buffer.from(arrayBuffer)
+```
+
+### convert buffer to arraybuffer
+
+To convert a `Buffer` to an `ArrayBuffer`, use the `.buffer` property (which is present on all `Uint8Array` objects):
+
+```js
+var arrayBuffer = buffer.buffer.slice(
+  buffer.byteOffset, buffer.byteOffset + buffer.byteLength
+)
+```
+
+Alternatively, use the [`to-arraybuffer`](https://www.npmjs.com/package/to-arraybuffer) module.
+
+## performance
+
+See perf tests in `/perf`.
+
+`BrowserBuffer` is the browser `buffer` module (this repo). `Uint8Array` is included as a
+sanity check (since `BrowserBuffer` uses `Uint8Array` under the hood, `Uint8Array` will
+always be at least a bit faster). Finally, `NodeBuffer` is the node.js buffer module,
+which is included to compare against.
+
+NOTE: Performance has improved since these benchmarks were taken. PR welcome to update the README.

+## Testing the project
+
+First, install the project:
+
+    npm install
+
+Then, to run tests in Node.js, run:
+
+    npm run test-node
+
+To test locally in a browser, you can run:
+
+    npm run test-browser-es5-local # For ES5 browsers that don't support ES6
+    npm run test-browser-es6-local # For ES6 compliant browsers
+
+This will print out a URL that you can then open in a browser to run the tests, using [airtap](https://www.npmjs.com/package/airtap).
+
+To run automated browser tests using Saucelabs, ensure that your `SAUCE_USERNAME` and `SAUCE_ACCESS_KEY` environment variables are set, then run:
+
+    npm test
+
+This is what's run in Travis, to check against various browsers. The list of browsers is kept in the `bin/airtap-es5.yml` and `bin/airtap-es6.yml` files.

+# Contributing guide
+
+Want to contribute to Clipboard.js? Awesome!
+There are many ways you can contribute, see below.
+
+## Opening issues
+
+Open an issue to report bugs or to propose new features.
+
+- Reporting bugs: describe the bug as clearly as you can, including steps to reproduce, what happened and what you were expecting to happen. Also include browser version, OS and other related software's (npm, Node.js, etc) versions when applicable.
+
+- Proposing features: explain the proposed feature, what it should do, why it is useful, how users should use it. Give us as much info as possible so it will be easier to discuss, access and implement the proposed feature. When you're unsure about a certain aspect of the feature, feel free to leave it open for others to discuss and find an appropriate solution.
+
+## Proposing pull requests
+
+Pull requests are very welcome. Note that if you are going to propose drastic changes, be sure to open an issue for discussion first, to make sure that your PR will be accepted before you spend effort coding it.
+
+Fork the Clipboard.js repository, clone it locally and create a branch for your proposed bug fix or new feature. Avoid working directly on the master branch.
+
+Implement your bug fix or feature, write tests to cover it and make sure all tests are passing (run a final `npm test` to make sure everything is correct). Then commit your changes, push your bug fix/feature branch to the origin (your forked repo) and open a pull request to the upstream (the repository you originally forked)'s master branch.
+
+## Documentation
+
+Documentation is extremely important and takes a fair deal of time and effort to write and keep updated. Please submit any and all improvements you can make to the repository's docs.
+
+## Known issues
+If you're using npm@3 you'll probably face some issues related to peerDependencies.

+![Killing Flash](https://img.shields.io/badge/killing-flash-brightgreen.svg?style=flat)
+
+> Modern copy to clipboard. No Flash. Just 3kb gzipped.
+
+<a href="https://clipboardjs.com/"><img width="728" src="https://cloud.githubusercontent.com/assets/398893/16165747/a0f6fc46-349a-11e6-8c9b-c5fd58d9099c.png" alt="Demo"></a>
+
+## Why
+
+Copying text to the clipboard shouldn't be hard. It shouldn't require dozens of steps to configure or hundreds of KBs to load. But most of all, it shouldn't depend on Flash or any bloated framework.
+
+That's why clipboard.js exists.
+
+## Install
+
+You can get it on npm.
+
+```
+npm install clipboard --save
+```
+
+Or if you're not into package management, just [download a ZIP](https://github.com/zenorocha/clipboard.js/archive/master.zip) file.
+
+## Setup
+
+First, include the script located on the `dist` folder or load it from [a third-party CDN provider](https://github.com/zenorocha/clipboard.js/wiki/CDN-Providers).
+
+```html
+<script src="dist/clipboard.min.js"></script>
+```
+
+Now, you need to instantiate it by [passing a DOM selector](https://github.com/zenorocha/clipboard.js/blob/master/demo/constructor-selector.html#L18), [HTML element](https://github.com/zenorocha/clipboard.js/blob/master/demo/constructor-node.html#L16-L17), or [list of HTML elements](https://github.com/zenorocha/clipboard.js/blob/master/demo/constructor-nodelist.html#L18-L19).
+
+```js
+new ClipboardJS('.btn');
+```
+
+Internally, we need to fetch all elements that matches with your selector and attach event listeners for each one. But guess what? If you have hundreds of matches, this operation can consume a lot of memory.
+
+For this reason we use [event delegation](https://stackoverflow.com/questions/1687296/what-is-dom-event-delegation) which replaces multiple event listeners with just a single listener. After all, [#perfmatters](https://twitter.com/hashtag/perfmatters).
+
+# Usage
+
+We're living a _declarative renaissance_, that's why we decided to take advantage of [HTML5 data attributes](https://developer.mozilla.org/en-US/docs/Web/Guide/HTML/Using_data_attributes) for better usability.
+
+### Copy text from another element
+
+A pretty common use case is to copy content from another element. You can do that by adding a `data-clipboard-target` attribute in your trigger element.
+
+The value you include on this attribute needs to match another's element selector.
+
+<a href="https://clipboardjs.com/#example-target"><img width="473" alt="example-2" src="https://cloud.githubusercontent.com/assets/398893/9983467/a4946aaa-5fb1-11e5-9780-f09fcd7ca6c8.png"></a>
+
+```html
+<!-- Target -->
+<input id="foo" value="https://github.com/zenorocha/clipboard.js.git">
+
+<!-- Trigger -->
+<button class="btn" data-clipboard-target="#foo">
+    <img src="assets/clippy.svg" alt="Copy to clipboard">
+</button>
+```
+
+### Cut text from another element
+
+Additionally, you can define a `data-clipboard-action` attribute to specify if you want to either `copy` or `cut` content.
+
+If you omit this attribute, `copy` will be used by default.
+
+<a href="https://clipboardjs.com/#example-action"><img width="473" alt="example-3" src="https://cloud.githubusercontent.com/assets/398893/10000358/7df57b9c-6050-11e5-9cd1-fbc51d2fd0a7.png"></a>
+
+```html
+<!-- Target -->
+<textarea id="bar">Mussum ipsum cacilds...</textarea>
+
+<!-- Trigger -->
+<button class="btn" data-clipboard-action="cut" data-clipboard-target="#bar">
+    Cut to clipboard
+</button>
+```
+
+As you may expect, the `cut` action only works on `<input>` or `<textarea>` elements.
+
+### Copy text from attribute
+
+Truth is, you don't even need another element to copy its content from. You can just include a `data-clipboard-text` attribute in your trigger element.
+
+<a href="https://clipboardjs.com/#example-text"><img width="147" alt="example-1" src="https://cloud.githubusercontent.com/assets/398893/10000347/6e16cf8c-6050-11e5-9883-1c5681f9ec45.png"></a>
+
+```html
+<!-- Trigger -->
+<button class="btn" data-clipboard-text="Just because you can doesn't mean you should — clipboard.js">
+    Copy to clipboard
+</button>
+```
+
+## Events
+
+There are cases where you'd like to show some user feedback or capture what has been selected after a copy/cut operation.
+
+That's why we fire custom events such as `success` and `error` for you to listen and implement your custom logic.
+
+```js
+var clipboard = new ClipboardJS('.btn');
+
+clipboard.on('success', function(e) {
+    console.info('Action:', e.action);
+    console.info('Text:', e.text);
+    console.info('Trigger:', e.trigger);
+
+    e.clearSelection();
+});
+
+clipboard.on('error', function(e) {
+    console.error('Action:', e.action);
+    console.error('Trigger:', e.trigger);
+});
+```
+
+For a live demonstration, go to this [site](https://clipboardjs.com/) and open your console.
+
+## Tooltips
+
+Each application has different design needs, that's why clipboard.js does not include any CSS or built-in tooltip solution.
+
+The tooltips you see on the [demo site](https://clipboardjs.com/) were built using [GitHub's Primer](https://primer.style/css/components/tooltips). You may want to check that out if you're looking for a similar look and feel.
+
+## Advanced Options
+
+If you don't want to modify your HTML, there's a pretty handy imperative API for you to use. All you need to do is declare a function, do your thing, and return a value.
+
+For instance, if you want to dynamically set a `target`, you'll need to return a Node.
+
+```js
+new ClipboardJS('.btn', {
+    target: function(trigger) {
+        return trigger.nextElementSibling;
+    }
+});
+```
+
+If you want to dynamically set a `text`, you'll return a String.
+
+```js
+new ClipboardJS('.btn', {
+    text: function(trigger) {
+        return trigger.getAttribute('aria-label');
+    }
+});
+```
+
+For use in Bootstrap Modals or with any other library that changes the focus you'll want to set the focused element as the `container` value.
+
+```js
+new ClipboardJS('.btn', {
+    container: document.getElementById('modal')
+});
+```
+
+Also, if you are working with single page apps, you may want to manage the lifecycle of the DOM more precisely. Here's how you clean up the events and objects that we create.
+
+```js
+var clipboard = new ClipboardJS('.btn');
+clipboard.destroy();
+```
+
+## Browser Support
+
+This library relies on both [Selection](https://developer.mozilla.org/en-US/docs/Web/API/Selection) and [execCommand](https://developer.mozilla.org/en-US/docs/Web/API/Document/execCommand) APIs. The first one is [supported by all browsers](https://caniuse.com/#search=selection) while the second one is supported in the following browsers.
+
+| <img src="https://clipboardjs.com/assets/images/chrome.png" width="48px" height="48px" alt="Chrome logo"> | <img src="https://clipboardjs.com/assets/images/edge.png" width="48px" height="48px" alt="Edge logo"> | <img src="https://clipboardjs.com/assets/images/firefox.png" width="48px" height="48px" alt="Firefox logo"> | <img src="https://clipboardjs.com/assets/images/ie.png" width="48px" height="48px" alt="Internet Explorer logo"> | <img src="https://clipboardjs.com/assets/images/opera.png" width="48px" height="48px" alt="Opera logo"> | <img src="https://clipboardjs.com/assets/images/safari.png" width="48px" height="48px" alt="Safari logo"> |
+|:---:|:---:|:---:|:---:|:---:|:---:|
+| 42+ ✔ | 12+ ✔ | 41+ ✔ | 9+ ✔ | 29+ ✔ | 10+ ✔ |
+
+The good news is that clipboard.js gracefully degrades if you need to support older browsers. All you have to do is show a tooltip saying `Copied!` when `success` event is called and `Press Ctrl+C to copy` when `error` event is called because the text is already selected.
+
+You can also check if clipboard.js is supported or not by running `ClipboardJS.isSupported()`, that way you can hide copy/cut buttons from the UI.
+
+## Bonus
+
+A browser extension that adds a "copy to clipboard" button to every code block on *GitHub, MDN, Gist, StackOverflow, StackExchange, npm, and even Medium.*
+
+Install for [Chrome](https://chrome.google.com/webstore/detail/codecopy/fkbfebkcoelajmhanocgppanfoojcdmg) and [Firefox](https://addons.mozilla.org/en-US/firefox/addon/codecopy/).

+[![Coverage Status](https://coveralls.io/repos/yargs/cliui/badge.svg?branch=)](https://coveralls.io/r/yargs/cliui?branch=)
+[![NPM version](https://img.shields.io/npm/v/cliui.svg)](https://www.npmjs.com/package/cliui)

+
+easily create complex multi-column command-line-interfaces.
+
+## Example
+
+```js
+var ui = require('cliui')()
+
+ui.div('Usage: $0 [command] [options]')
+
+ui.div({
+  text: 'Options:',
+  padding: [2, 0, 2, 0]
+})
+
+ui.div(
+  {
+    text: "-f, --file",
+    width: 20,
+    padding: [0, 4, 0, 4]
+  },
+  {
+    text: "the file to load." +
+      chalk.green("(if this description is long it wraps).")
+    ,
+    width: 20
+  },
+  {
+    text: chalk.red("[required]"),
+    align: 'right'
+  }
+)
+
+console.log(ui.toString())
+```
+

+
+## Layout DSL
+
+cliui exposes a simple layout DSL:
+
+If you create a single `ui.div`, passing a string rather than an
+object:
+
+* `\n`: characters will be interpreted as new rows.
+* `\t`: characters will be interpreted as new columns.
+* `\s`: characters will be interpreted as padding.
+
+**as an example...**
+
+```js
+var ui = require('./')({
+  width: 60
+})
+
+ui.div(
+  'Usage: node ./bin/foo.js\n' +
+  '  <regex>\t  provide a regex\n' +
+  '  <glob>\t  provide a glob\t [required]'
+)
+
+console.log(ui.toString())
+```
+
+**will output:**
+
+```shell
+Usage: node ./bin/foo.js
+  <regex>  provide a regex
+  <glob>   provide a glob          [required]
+```
+
+## Methods
+
+```js
+cliui = require('cliui')
+```
+
+### cliui({width: integer})
+
+Specify the maximum width of the UI being generated.
+If no width is provided, cliui will try to get the current window's width and use it, and if that doesn't work, width will be set to `80`.
+
+### cliui({wrap: boolean})
+
+Enable or disable the wrapping of text in a column.
+
+### cliui.div(column, column, column)
+
+Create a row with any number of columns, a column
+can either be a string, or an object with the following
+options:
+
+* **text:** some text to place in the column.
+* **width:** the width of a column.
+* **align:** alignment, `right` or `center`.
+* **padding:** `[top, right, bottom, left]`.
+* **border:** should a border be placed around the div?
+
+### cliui.span(column, column, column)
+
+Similar to `div`, except the next row will be appended without
+a new line being created.
+
+### cliui.resetOutput()
+
+Resets the UI elements of the current cliui instance, maintaining the values
+set for `width` and `wrap`.

+# color-convert
+
+[![Build Status](https://travis-ci.org/Qix-/color-convert.svg?branch=master)](https://travis-ci.org/Qix-/color-convert)
+
+Color-convert is a color conversion library for JavaScript and node.
+It converts all ways between `rgb`, `hsl`, `hsv`, `hwb`, `cmyk`, `ansi`, `ansi16`, `hex` strings, and CSS `keyword`s (will round to closest):
+
+```js
+var convert = require('color-convert');
+
+convert.rgb.hsl(140, 200, 100);             // [96, 48, 59]
+convert.keyword.rgb('blue');                // [0, 0, 255]
+
+var rgbChannels = convert.rgb.channels;     // 3
+var cmykChannels = convert.cmyk.channels;   // 4
+var ansiChannels = convert.ansi16.channels; // 1
+```
+
+# Install
+
+```console
+$ npm install color-convert
+```
+
+# API
+
+Simply get the property of the _from_ and _to_ conversion that you're looking for.
+
+All functions have a rounded and unrounded variant. By default, return values are rounded. To get the unrounded (raw) results, simply tack on `.raw` to the function.
+
+All 'from' functions have a hidden property called `.channels` that indicates the number of channels the function expects (not including alpha).
+
+```js
+var convert = require('color-convert');
+
+// Hex to LAB
+convert.hex.lab('DEADBF');         // [ 76, 21, -2 ]
+convert.hex.lab.raw('DEADBF');     // [ 75.56213190997677, 20.653827952644754, -2.290532499330533 ]
+
+// RGB to CMYK
+convert.rgb.cmyk(167, 255, 4);     // [ 35, 0, 98, 0 ]
+convert.rgb.cmyk.raw(167, 255, 4); // [ 34.509803921568626, 0, 98.43137254901961, 0 ]
+```
+
+### Arrays
+All functions that accept multiple arguments also support passing an array.
+
+Note that this does **not** apply to functions that convert from a color that only requires one value (e.g. `keyword`, `ansi256`, `hex`, etc.)
+
+```js

+## Routing
+
+Conversions that don't have an _explicitly_ defined conversion (in [conversions.js](conversions.js)), but can be converted by means of sub-conversions (e.g. XYZ -> **RGB** -> CMYK), are automatically routed together. This allows just about any color model supported by `color-convert` to be converted to any other model, so long as a sub-conversion path exists. This is also true for conversions requiring more than one step in between (e.g. LCH -> **LAB** -> **XYZ** -> **RGB** -> Hex).
+
+Keep in mind that extensive conversions _may_ result in a loss of precision, and exist only to be complete. For a list of "direct" (single-step) conversions, see [conversions.js](conversions.js).
