+
+This little beautifier will reformat and re-indent bookmarklets, ugly
+JavaScript, unpack scripts packed by Dean Edward’s popular packer,
+as well as partly deobfuscate scripts processed by the npm package
+[javascript-obfuscator](https://github.com/javascript-obfuscator/javascript-obfuscator).
+
+Open [beautifier.io](https://beautifier.io/) to try it out.  Options are available via the UI.
+
+# Contributors Needed
+I'm putting this front and center above because existing owners have very limited time to work on this project currently.
+This is a popular project and widely used but it desperately needs contributors who have time to commit to fixing both
+customer facing bugs and underlying problems with the internal design and implementation.
+
+If you are interested, please take a look at the [CONTRIBUTING.md](https://github.com/beautify-web/js-beautify/blob/main/CONTRIBUTING.md) then fix an issue marked with the ["Good first issue"](https://github.com/beautify-web/js-beautify/issues?q=is%3Aissue+is%3Aopen+label%3A%22good+first+issue%22) label and submit a PR. Repeat as often as possible.  Thanks!
+
+
+# Installation
+
+You can install the beautifier for node.js or python.
+
+## Node.js JavaScript
+
+You may install the NPM package `js-beautify`. When installed globally, it provides an executable `js-beautify` script. As with the Python script, the beautified result is sent to `stdout` unless otherwise configured.
+
+```bash
+$ npm -g install js-beautify
+$ js-beautify foo.js
+```
+
+You can also use `js-beautify` as a `node` library (install locally, the `npm` default):
+
+```bash
+$ npm install js-beautify
+```
+
+## Node.js JavaScript (vNext)
+
+The above install the latest stable release. To install beta or RC versions:
+
+```bash
+$ npm install js-beautify@next
+```
+
+## Web Library
+The beautifier can be added on your page as web library.
+
+JS Beautifier is hosted on two CDN services: [cdnjs](https://cdnjs.com/libraries/js-beautify) and rawgit.
+
+To pull the latest version from one of these services include one set of the script tags below in your document:
+```html
+<script src="https://cdnjs.cloudflare.com/ajax/libs/js-beautify/1.14.0/beautify.js"></script>
+<script src="https://cdnjs.cloudflare.com/ajax/libs/js-beautify/1.14.0/beautify-css.js"></script>
+<script src="https://cdnjs.cloudflare.com/ajax/libs/js-beautify/1.14.0/beautify-html.js"></script>
+
+<script src="https://cdnjs.cloudflare.com/ajax/libs/js-beautify/1.14.0/beautify.min.js"></script>
+<script src="https://cdnjs.cloudflare.com/ajax/libs/js-beautify/1.14.0/beautify-css.min.js"></script>
+<script src="https://cdnjs.cloudflare.com/ajax/libs/js-beautify/1.14.0/beautify-html.min.js"></script>
+
+<script src="https://cdn.rawgit.com/beautify-web/js-beautify/v1.14.0/js/lib/beautify.js"></script>
+<script src="https://cdn.rawgit.com/beautify-web/js-beautify/v1.14.0/js/lib/beautify-css.js"></script>
+<script src="https://cdn.rawgit.com/beautify-web/js-beautify/v1.14.0/js/lib/beautify-html.js"></script>
+```
+
+Older versions are available by changing the version number.
+
+Disclaimer: These are free services, so there are [no uptime or support guarantees](https://github.com/rgrove/rawgit/wiki/Frequently-Asked-Questions#i-need-guaranteed-100-uptime-should-i-use-cdnrawgitcom).
+
+
+## Python
+To install the Python version of the beautifier:
+
+```bash
+$ pip install jsbeautifier
+```
+Unlike the JavaScript version, the Python version can only reformat JavaScript. It does not work against HTML or CSS files, but you can install _css-beautify_ for CSS:
+
+```bash
+$ pip install cssbeautifier
+```
+
+# Usage
+You can beautify javascript using JS Beautifier in your web browser, or on the command-line using node.js or python.
+
+## Web Browser
+Open [beautifier.io](https://beautifier.io/).  Options are available via the UI.
+
+## Web Library
+The script tags above expose three functions: `js_beautify`, `css_beautify`, and `html_beautify`.
+
+## Node.js JavaScript
+
+When installed globally, the beautifier provides an executable `js-beautify` script. The beautified result is sent to `stdout` unless otherwise configured.
+
+```bash
+$ js-beautify foo.js
+```
+
+To use `js-beautify` as a `node` library (after install locally), import and call the appropriate beautifier method for javascript (js), css, or html.  All three method signatures are `beautify(code, options)`. `code` is the string of code to be beautified. options is an object with the settings you would like used to beautify the code.
+
+The configuration option names are the same as the CLI names but with underscores instead of dashes.  For example, `--indent-size 2 --space-in-empty-paren` would be `{ indent_size: 2, space_in_empty_paren: true }`.
+
+```js
+var beautify = require('js-beautify').js,
+    fs = require('fs');
+
+fs.readFile('foo.js', 'utf8', function (err, data) {
+    if (err) {
+        throw err;
+    }
+    console.log(beautify(data, { indent_size: 2, space_in_empty_paren: true }));
+});
+```
+
+## Python
+After installing, to beautify using Python:
+
+```bash
+$ js-beautify file.js
+```
+
+Beautified output goes to `stdout` by default.
+
+To use `jsbeautifier` as a library is simple:
+
+```python
+import jsbeautifier
+res = jsbeautifier.beautify('your javascript string')
+res = jsbeautifier.beautify_file('some_file.js')
+```
+
+...or, to specify some options:
+
+```python
+opts = jsbeautifier.default_options()
+opts.indent_size = 2
+opts.space_in_empty_paren = True
+res = jsbeautifier.beautify('some javascript', opts)
+```
+
+The configuration option names are the same as the CLI names but with underscores instead of dashes.  The example above would be set on the command-line as `--indent-size 2 --space-in-empty-paren`.
+
+
+# Options

+```
+
+Which correspond to the underscored option keys for both library interfaces
+
+**defaults per CLI options**
+```json
+{
+    "indent_size": 4,
+    "indent_char": " ",
+    "indent_with_tabs": false,
+    "editorconfig": false,
+    "eol": "\n",
+    "end_with_newline": false,
+    "indent_level": 0,
+    "preserve_newlines": true,
+    "max_preserve_newlines": 10,
+    "space_in_paren": false,
+    "space_in_empty_paren": false,
+    "jslint_happy": false,
+    "space_after_anon_function": false,
+    "space_after_named_function": false,
+    "brace_style": "collapse",
+    "unindent_chained_methods": false,
+    "break_chained_methods": false,
+    "keep_array_indentation": false,
+    "unescape_strings": false,
+    "wrap_line_length": 0,
+    "e4x": false,
+    "comma_first": false,
+    "operator_position": "before-newline",
+    "indent_empty_lines": false,
+    "templating": ["auto"]
+}
+```
+
+**defaults not exposed in the cli**
+```json
+{
+  "eval_code": false,
+  "space_before_conditional": true
+}
+```
+
+Notice not all defaults are exposed via the CLI.  Historically, the Python and
+JS APIs have not been 100% identical. There are still a
+few other additional cases keeping us from 100% API-compatibility.
+
+
+## Loading settings from environment or .jsbeautifyrc (JavaScript-Only)
+
+In addition to CLI arguments, you may pass config to the JS executable via:
+
+ * any `jsbeautify_`-prefixed environment variables
+ * a `JSON`-formatted file indicated by the `--config` parameter
+ * a `.jsbeautifyrc` file containing `JSON` data at any level of the filesystem above `$PWD`
+
+Configuration sources provided earlier in this stack will override later ones.
+
+## Setting inheritance and Language-specific overrides
+
+The settings are a shallow tree whose values are inherited for all languages, but
+can be overridden.  This works for settings passed directly to the API in either implementation.
+In the Javascript implementation, settings loaded from a config file, such as .jsbeautifyrc, can also use inheritance/overriding.
+
+Below is an example configuration tree showing all the supported locations
+for language override nodes.  We'll use `indent_size` to discuss how this configuration would behave, but any number of settings can be inherited or overridden:
+
+```json
+{
+    "indent_size": 4,
+    "html": {
+        "end_with_newline": true,
+        "js": {
+            "indent_size": 2
+        },
+        "css": {
+            "indent_size": 2
+        }
+    },
+    "css": {
+        "indent_size": 1
+    },
+    "js": {
+       "preserve-newlines": true
+    }
+}
+```
+
+Using the above example would have the following result:
+
+* HTML files
+  * Inherit `indent_size` of 4 spaces from the top-level setting.
+  * The files would also end with a newline.
+  * JavaScript and CSS inside HTML
+    * Inherit the HTML `end_with_newline` setting.
+    * Override their indentation to 2 spaces.
+* CSS files
+  * Override the top-level setting to an `indent_size` of 1 space.
+* JavaScript files
+  * Inherit `indent_size` of 4 spaces from the top-level setting.
+  * Set `preserve-newlines` to `true`.
+
+## CSS & HTML
+
+In addition to the `js-beautify` executable, `css-beautify` and `html-beautify`
+are also provided as an easy interface into those scripts. Alternatively,
+`js-beautify --css` or `js-beautify --html` will accomplish the same thing, respectively.
+
+```js
+// Programmatic access
+var beautify_js = require('js-beautify'); // also available under "js" export
+var beautify_css = require('js-beautify').css;
+var beautify_html = require('js-beautify').html;
+
+// All methods accept two arguments, the string to be beautified, and an options object.
+```
+
+The CSS & HTML beautifiers are much simpler in scope, and possess far fewer options.
+
+```text
+CSS Beautifier Options:
+  -s, --indent-size                  Indentation size [4]
+  -c, --indent-char                  Indentation character [" "]

+  -e, --eol                          Character(s) to use as line terminators. (default newline - "\\n")
+  -n, --end-with-newline             End output with newline
+  -b, --brace-style                  [collapse|expand] ["collapse"]
+  -L, --selector-separator-newline   Add a newline between multiple selectors
+  -N, --newline-between-rules        Add a newline between CSS rules
+  --indent-empty-lines               Keep indentation on empty lines
+
+HTML Beautifier Options:
+  -s, --indent-size                  Indentation size [4]
+  -c, --indent-char                  Indentation character [" "]
+  -t, --indent-with-tabs             Indent with tabs, overrides -s and -c
+  -e, --eol                          Character(s) to use as line terminators. (default newline - "\\n")
+  -n, --end-with-newline             End output with newline
+  -p, --preserve-newlines            Preserve existing line-breaks (--no-preserve-newlines disables)
+  -m, --max-preserve-newlines        Maximum number of line-breaks to be preserved in one chunk [10]
+  -I, --indent-inner-html            Indent <head> and <body> sections. Default is false.
+  -b, --brace-style                  [collapse-preserve-inline|collapse|expand|end-expand|none] ["collapse"]
+  -S, --indent-scripts               [keep|separate|normal] ["normal"]
+  -w, --wrap-line-length             Maximum characters per line (0 disables) [250]
+  -A, --wrap-attributes              Wrap attributes to new lines [auto|force|force-aligned|force-expand-multiline|aligned-multiple|preserve|preserve-aligned] ["auto"]
+  -i, --wrap-attributes-indent-size  Indent wrapped attributes to after N characters [indent-size] (ignored if wrap-attributes is "aligned")
+  -d, --inline                       List of tags to be considered inline tags
+  -U, --unformatted                  List of tags (defaults to inline) that should not be reformatted
+  -T, --content_unformatted          List of tags (defaults to pre) whose content should not be reformatted
+  -E, --extra_liners                 List of tags (defaults to [head,body,/html] that should have an extra newline before them.
+  --editorconfig                     Use EditorConfig to set up the options
+  --indent_scripts                   Sets indent level inside script tags ("normal", "keep", "separate")
+  --unformatted_content_delimiter    Keep text content together between this string [""]
+  --indent-empty-lines               Keep indentation on empty lines
+  --templating                       List of templating languages (auto,none,django,erb,handlebars,php,smarty) ["auto"] auto = none in JavaScript, all in html
+```
+
+## Directives
+
+Directives let you control the behavior of the Beautifier from within your source files. Directives are placed in comments inside the file.  Directives are in the format `/* beautify {name}:{value} */` in CSS and JavaScript. In HTML they are formatted as `<!-- beautify {name}:{value} -->`.
+
+### Ignore directive
+
+The `ignore` directive makes the beautifier completely ignore part of a file, treating it as literal text that is not parsed.
+The input below will remain unchanged after beautification:
+
+```js
+// Use ignore when the content is not parsable in the current language, JavaScript in this case.
+var a =  1;
+/* beautify ignore:start */
+ {This is some strange{template language{using open-braces?
+/* beautify ignore:end */
+```
+
+### Preserve directive
+
+NOTE: this directive only works in HTML and JavaScript, not CSS.
+
+The `preserve` directive makes the Beautifier parse and then keep the existing formatting of a section of code.
+
+The input below will remain unchanged after beautification:
+
+```js
+// Use preserve when the content is valid syntax in the current language, JavaScript in this case.
+// This will parse the code and preserve the existing formatting.
+/* beautify preserve:start */
+{
+    browserName: 'internet explorer',
+    platform:    'Windows 7',
+    version:     '8'
+}
+/* beautify preserve:end */
+```
