-
-A tiny JavaScript debugging utility modelled after Node.js core's debugging
-technique. Works in Node.js and web browsers.
-
-## Installation
-
-```bash
-$ npm install debug
-```
-
-## Usage
-
-`debug` exposes a function; simply pass this function the name of your module, and it will return a decorated version of `console.error` for you to pass debug statements to. This will allow you to toggle the debug output for different parts of your module as well as the module as a whole.
-
-Example [_app.js_](./examples/node/app.js):
-
-```js
-var debug = require('debug')('http')
-  , http = require('http')
-  , name = 'My App';
-
-// fake app
-
-debug('booting %o', name);
-
-http.createServer(function(req, res){
-  debug(req.method + ' ' + req.url);
-  res.end('hello\n');
-}).listen(3000, function(){
-  debug('listening');
-});
-
-// fake worker of some kind
-
-require('./worker');
-```
-
-Example [_worker.js_](./examples/node/worker.js):
-
-```js
-var a = require('debug')('worker:a')
-  , b = require('debug')('worker:b');
-
-function work() {
-  a('doing lots of uninteresting work');
-  setTimeout(work, Math.random() * 1000);
-}
-
-work();
-
-function workb() {
-  b('doing some work');
-  setTimeout(workb, Math.random() * 2000);
-}
-
-workb();
-```
-
-The `DEBUG` environment variable is then used to enable these based on space or
-comma-delimited names.
-
-Here are some examples:
-
-screen shot 2017-08-08 at 12 53 04 pm
-screen shot 2017-08-08 at 12 53 38 pm
-screen shot 2017-08-08 at 12 53 25 pm
-
-#### Windows command prompt notes
-
-##### CMD
-
-On Windows the environment variable is set using the `set` command.
-
-```cmd
-set DEBUG=*,-not_this
-```
-
-Example:
-
-```cmd
-set DEBUG=* & node app.js
-```
-
-##### PowerShell (VS Code default)
-
-PowerShell uses different syntax to set environment variables.
-
-```cmd
-$env:DEBUG = "*,-not_this"
-```
-
-Example:
-
-```cmd
-$env:DEBUG='app';node app.js
-```
-
-Then, run the program to be debugged as usual.
-
-npm script example:
-```js
-  "windowsDebug": "@powershell -Command $env:DEBUG='*';node app.js",
-```
-
-## Namespace Colors
-
-Every debug instance has a color generated for it based on its namespace name.
-This helps when visually parsing the debug output to identify which debug instance
-a debug line belongs to.
-
-#### Node.js
-
-In Node.js, colors are enabled when stderr is a TTY. You also _should_ install
-the [`supports-color`](https://npmjs.org/supports-color) module alongside debug,
-otherwise debug will only use a small handful of basic colors.
-
-
-
-#### Web Browser
-
-Colors are also enabled on "Web Inspectors" that understand the `%c` formatting

-## Millisecond diff
-
-When actively developing an application it can be useful to see when the time spent between one `debug()` call and the next. Suppose for example you invoke `debug()` before requesting a resource, and after as well, the "+NNNms" will show you how much time was spent between calls.
-
-
-
-When stdout is not a TTY, `Date#toISOString()` is used, making it more useful for logging the debug information as shown below:
-
-
-
-
-## Conventions
-
-If you're using this in one or more of your libraries, you _should_ use the name of your library so that developers may toggle debugging as desired without guessing names. If you have more than one debuggers you _should_ prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser".  If you append a "*" to the end of your name, it will always be enabled regardless of the setting of the DEBUG environment variable.  You can then use it for normal output as well as debug output.
-
-## Wildcards
-
-The `*` character may be used as a wildcard. Suppose for example your library has
-debuggers named "connect:bodyParser", "connect:compress", "connect:session",
-instead of listing all three with
-`DEBUG=connect:bodyParser,connect:compress,connect:session`, you may simply do
-`DEBUG=connect:*`, or to run everything using this module simply use `DEBUG=*`.
-
-You can also exclude specific debuggers by prefixing them with a "-" character.
-For example, `DEBUG=*,-connect:*` would include all debuggers except those
-starting with "connect:".
-
-## Environment Variables
-
-When running through Node.js, you can set a few environment variables that will
-change the behavior of the debug logging:
-
-| Name      | Purpose                                         |
-|-----------|-------------------------------------------------|
-| `DEBUG`   | Enables/disables specific debugging namespaces. |
-| `DEBUG_HIDE_DATE` | Hide date from debug output (non-TTY).  |
-| `DEBUG_COLORS`| Whether or not to use colors in the debug output. |
-| `DEBUG_DEPTH` | Object inspection depth.                    |
-| `DEBUG_SHOW_HIDDEN` | Shows hidden properties on inspected objects. |
-
-
-__Note:__ The environment variables beginning with `DEBUG_` end up being
-converted into an Options object that gets used with `%o`/`%O` formatters.
-See the Node.js documentation for
-[`util.inspect()`](https://nodejs.org/api/util.html#util_util_inspect_object_options)
-for the complete list.
-
-## Formatters
-
-Debug uses [printf-style](https://wikipedia.org/wiki/Printf_format_string) formatting.
-Below are the officially supported formatters:
-
-| Formatter | Representation |
-|-----------|----------------|
-| `%O`      | Pretty-print an Object on multiple lines. |
-| `%o`      | Pretty-print an Object all on a single line. |
-| `%s`      | String. |
-| `%d`      | Number (both integer and float). |
-| `%j`      | JSON. Replaced with the string '[Circular]' if the argument contains circular references. |
-| `%%`      | Single percent sign ('%'). This does not consume an argument. |
-
-
-### Custom formatters
-
-You can add custom formatters by extending the `debug.formatters` object.
-For example, if you wanted to add support for rendering a Buffer as hex with
-`%h`, you could do something like:
-
-```js
-const createDebug = require('debug')
-createDebug.formatters.h = (v) => {
-  return v.toString('hex')
-}
-
-// …elsewhere
-const debug = createDebug('foo')
-debug('this is hex: %h', new Buffer('hello world'))
-//   foo this is hex: 68656c6c6f20776f726c6421 +0ms
-```
-
-
-## Browser Support
-
-You can build a browser-ready script using [browserify](https://github.com/substack/node-browserify),
-or just use the [browserify-as-a-service](https://wzrd.in/) [build](https://wzrd.in/standalone/debug@latest),
-if you don't want to build it yourself.
-
-Debug's enable state is currently persisted by `localStorage`.
-Consider the situation shown below where you have `worker:a` and `worker:b`,
-and wish to debug both. You can enable this using `localStorage.debug`:
-
-```js
-localStorage.debug = 'worker:*'
-```
-
-And then refresh the page.
-
-```js
-a = debug('worker:a');
-b = debug('worker:b');
-
-setInterval(function(){
-  a('doing some work');
-}, 1000);
-
-setInterval(function(){
-  b('doing some work');
-}, 1200);
-```
-
-In Chromium-based web browsers (e.g. Brave, Chrome, and Electron), the JavaScript console will—by default—only show messages logged by `debug` if the "Verbose" log level is _enabled_.
-
-
-
-## Output streams
-
-  By default `debug` will log to stderr, however this can be configured per-namespace by overriding the `log` method:
-
-Example [_stdout.js_](./examples/node/stdout.js):
-
-```js
-var debug = require('debug');
-var error = debug('app:error');
-
-// by default stderr is used
-error('goes to stderr!');
-
-var log = debug('app:log');
-// set this namespace to log via console.log
-log.log = console.log.bind(console); // don't forget to bind to console!
-log('goes to stdout');
-error('still goes to stderr!');
-
-// set all output to go via console.info
-// overrides all per-namespace log settings
-debug.log = console.info.bind(console);
-error('now goes to stdout via console.info');
-log('still goes to stdout, but via console.info now');
-```
-
-## Extend
-You can simply extend debugger 
-```js
-const log = require('debug')('auth');
-
-//creates new debug instance with extended namespace
-const logSign = log.extend('sign');
-const logLogin = log.extend('login');
-
-log('hello'); // auth hello
-logSign('hello'); //auth:sign hello
-logLogin('hello'); //auth:login hello
-```
-
-## Set dynamically
-
-You can also enable debug dynamically by calling the `enable()` method :
-
-```js
-let debug = require('debug');
-
-console.log(1, debug.enabled('test'));
-
-debug.enable('test');
-console.log(2, debug.enabled('test'));
-
-debug.disable();
-console.log(3, debug.enabled('test'));
-
-```
-
-print :   
-```
-1 false
-2 true
-3 false
-```
-
-Usage :  
-`enable(namespaces)`  
-`namespaces` can include modes separated by a colon and wildcards.
-   
-Note that calling `enable()` completely overrides previously set DEBUG variable : 
-
-```
-$ DEBUG=foo node -e 'var dbg = require("debug"); dbg.enable("bar"); console.log(dbg.enabled("foo"))'
-=> false
-```
-
-`disable()`
-
-Will disable all namespaces. The functions returns the namespaces currently
-enabled (and skipped). This can be useful if you want to disable debugging
-temporarily without knowing what was enabled to begin with.
-
-For example:
-
-```js
-let debug = require('debug');
-debug.enable('foo:*,-foo:bar');
-let namespaces = debug.disable();
-debug.enable(namespaces);
-```
-
-Note: There is no guarantee that the string will be identical to the initial
-enable string, but semantically they will be identical.
-
-## Checking whether a debug target is enabled
-
-After you've created a debug instance, you can determine whether or not it is
-enabled by checking the `enabled` property:
-
-```javascript
-const debug = require('debug')('http');
-
-if (debug.enabled) {
-  // do stuff...
-}
-```
-
-You can also manually toggle this property to force the debug instance to be
-enabled or disabled.
-
-## Usage in child processes
-
-Due to the way `debug` detects if the output is a TTY or not, colors are not shown in child processes when `stderr` is piped. A solution is to pass the `DEBUG_COLORS=1` environment variable to the child process.  
-For example:
-
-```javascript
-worker = fork(WORKER_WRAP_PATH, [workerPath], {
-  stdio: [
-    /* stdin: */ 0,
-    /* stdout: */ 'pipe',
-    /* stderr: */ 'pipe',
-    'ipc',
-  ],
-  env: Object.assign({}, process.env, {
-    DEBUG_COLORS: 1 // without this settings, colors won't be shown
-  }),
-});
-
-worker.stderr.pipe(process.stderr, { end: false });
-```

-
-[![Build Status](https://github.com/hexojs/hexo-renderer-stylus/workflows/Tester/badge.svg)](https://github.com/hexojs/hexo-renderer-stylus/actions/workflows/tester.yml)
-[![NPM version](https://badge.fury.io/js/hexo-renderer-stylus.svg)](https://www.npmjs.com/package/hexo-renderer-stylus)
-[![Coverage Status](https://img.shields.io/coveralls/hexojs/hexo-renderer-stylus.svg)](https://coveralls.io/r/hexojs/hexo-renderer-stylus?branch=master)
-
-Add support for [Stylus] with [nib] and other plugins.
-
-## Install
-
-Prerequisites:
-- Hexo 3: >= 0.2
-- Hexo 2: 0.1.x
-
-``` bash
-$ npm install hexo-renderer-stylus --save
-```
-
-## Options
-
-You can configure this plugin in `_config.yml`.
-
-``` yaml
-stylus:
-  compress: false
-  sourcemaps:
-    comment: true
-    inline: true
-    sourceRoot: ''
-    basePath: .
-  plugins: 'nib'
-```
-
-- **compress** - Compress generated CSS (default: `false`)
-- **sourcemaps**
-  - **comment** - Adds a comment with the `sourceMappingURL` to the generated CSS (default: `true`)
-  - **inline** - Inlines the sourcemap with full source text in base64 format (default: `false`)
-  - **sourceRoot** - `sourceRoot` property of the generated sourcemap
-  - **basePath** - Base path from which sourcemap and all sources are relative (default: `.`)
-- **plugins** - Stylus plugin(s) (default: `nib`)
-
-## Setting Stylus variables
-
-It is possible to set variables that can be used in Stylus.
-The purpose of setting variable is to avoid direct modification of the Stylus code,
-and thus to make themes more generic
-
-For example, instead of hardcoding:
-```stylus
-div
- color #FFCC44
-```
-
-You can refer to a variable:
-```stylus
-div
- color convert(hexo-config("moody_red"))
-```
-
-And in your **theme's** configuration, you can define this variable:
-```yml
-moody_red: "#8B0001"
-```
-
-(The "convert" function above is here to convert the string into an actual stylus color)
-
-You can also use the theme_config variable in the main `_config.yml`:
-```yml
-theme_config:
-  moody_red: "#8B0001"
-```
-
-[Stylus]: https://stylus-lang.com/
-[nib]: https://stylus.github.io/nib/
-
-## Extensibility
-
-This plugin provide a filter `stylus:renderer` to allows you extend it. When there's something you cannot do in Stylus, define it in JavaScript!
-
-For example, to define some global variable:
-
-```js
-hexo.extend.filter.register('stylus:renderer', function(style) {
-  style
-    // we may define a global variable by passing a `Node`
-    .define('has-canvas', require('stylus').nodes.false);
-    // stylus also casts JavaScript values to their Stylus equivalents when possible
-    .define('families', ['Helvetica Neue', 'Helvetica', 'sans-serif'])
-    // also allows you to provide a JavaScript-defined function to Stylus
-    .define('get-list', function(){
-      return ['foo', 'bar', 'baz'];
-    });
-})
-```
-
-Save the file in "scripts/" folder and run Hexo as usual.
-
-Notice: for more JavaScript api, refer to stylus's [documentation](https://stylus-lang.com/docs/js.html).

-[![Build Status](https://travis-ci.org/zeit/ms.svg?branch=master)](https://travis-ci.org/zeit/ms)
-[![Join the community on Spectrum](https://withspectrum.github.io/badge/badge.svg)](https://spectrum.chat/zeit)
-
-Use this package to easily convert various time formats to milliseconds.
-
-## Examples
-
-```js
-ms('2 days')  // 172800000
-ms('1d')      // 86400000
-ms('10h')     // 36000000
-ms('2.5 hrs') // 9000000
-ms('2h')      // 7200000
-ms('1m')      // 60000
-ms('5s')      // 5000
-ms('1y')      // 31557600000
-ms('100')     // 100
-ms('-3 days') // -259200000
-ms('-1h')     // -3600000
-ms('-200')    // -200
-```
-
-### Convert from Milliseconds
-
-```js
-ms(60000)             // "1m"
-ms(2 * 60000)         // "2m"
-ms(-3 * 60000)        // "-3m"
-ms(ms('10 hours'))    // "10h"
-```
-
-### Time Format Written-Out
-
-```js
-ms(60000, { long: true })             // "1 minute"
-ms(2 * 60000, { long: true })         // "2 minutes"
-ms(-3 * 60000, { long: true })        // "-3 minutes"
-ms(ms('10 hours'), { long: true })    // "10 hours"
-```
-
-## Features
-
-- Works both in [Node.js](https://nodejs.org) and in the browser
-- If a number is supplied to `ms`, a string with a unit is returned
-- If a string that contains the number is supplied, it returns it as a number (e.g.: it returns `100` for `'100'`)
-- If you pass a string with a number and a valid unit, the number of equivalent milliseconds is returned
-
-## Related Packages
-
-- [ms.macro](https://github.com/knpwrs/ms.macro) - Run `ms` as a macro at build-time.
-
-## Caught a Bug?
-
-1. [Fork](https://help.github.com/articles/fork-a-repo/) this repository to your own GitHub account and then [clone](https://help.github.com/articles/cloning-a-repository/) it to your local device
-2. Link the package to the global module directory: `npm link`
-3. Within the module you want to test your local development instance of ms, just link it to the dependencies: `npm link ms`. Instead of the default one from npm, Node.js will now use your clone of ms!
-
-As always, you can run the tests using: `npm test`

-### Generating a source map
-
-In depth guide:
-[**Compiling to JavaScript, and Debugging with Source Maps**](https://hacks.mozilla.org/2013/05/compiling-to-javascript-and-debugging-with-source-maps/)
-
-#### With SourceNode (high level API)
-
-```js
-function compile(ast) {
-  switch (ast.type) {
-  case 'BinaryExpression':
-    return new SourceNode(
-      ast.location.line,
-      ast.location.column,
-      ast.location.source,
-      [compile(ast.left), " + ", compile(ast.right)]
-    );
-  case 'Literal':
-    return new SourceNode(
-      ast.location.line,
-      ast.location.column,
-      ast.location.source,
-      String(ast.value)
-    );
-  // ...
-  default:
-    throw new Error("Bad AST");
-  }
-}
-
-var ast = parse("40 + 2", "add.js");
-console.log(compile(ast).toStringWithSourceMap({
-  file: 'add.js'
-}));
-// { code: '40 + 2',
-//   map: [object SourceMapGenerator] }
-```
-
-#### With SourceMapGenerator (low level API)
-
-```js
-var map = new SourceMapGenerator({
-  file: "source-mapped.js"
-});
-
-map.addMapping({
-  generated: {
-    line: 10,
-    column: 35
-  },
-  source: "foo.js",
-  original: {
-    line: 33,
-    column: 2
-  },
-  name: "christopher"
-});
-
-console.log(map.toString());
-// '{"version":3,"file":"source-mapped.js","sources":["foo.js"],"names":["christopher"],"mappings":";;;;;;;;;mCAgCEA"}'
-```
-
-## API
-
-Get a reference to the module:
-
-```js
-// Node.js
-var sourceMap = require('source-map');
-
-// Browser builds
-var sourceMap = window.sourceMap;
-
-// Inside Firefox
-const sourceMap = require("devtools/toolkit/sourcemap/source-map.js");
-```
-
-### SourceMapConsumer
-
-A `SourceMapConsumer` instance represents a parsed source map which we can query
-for information about the original file positions by giving it a file position
-in the generated source.
-
-#### SourceMapConsumer.initialize(options)
-
-When using `SourceMapConsumer` outside of node.js, for example on the Web, it
-needs to know from what URL to load `lib/mappings.wasm`. You must inform it by
-calling `initialize` before constructing any `SourceMapConsumer`s.
-
-The options object has the following properties:
-
-* `"lib/mappings.wasm"`: A `String` containing the URL of the
-  `lib/mappings.wasm` file, or an `ArrayBuffer` with the contents of `lib/mappings.wasm`.
-
-```js
-sourceMap.SourceMapConsumer.initialize({
-  "lib/mappings.wasm": "https://example.com/source-map/lib/mappings.wasm"
-});
-```
-
-#### new SourceMapConsumer(rawSourceMap)
-
-The only parameter is the raw source map (either as a string which can be
-`JSON.parse`'d, or an object). According to the spec, source maps have the
-following attributes:
-
-* `version`: Which version of the source map spec this map is following.
-
-* `sources`: An array of URLs to the original source files.
-
-* `names`: An array of identifiers which can be referenced by individual
-  mappings.
-
-* `sourceRoot`: Optional. The URL root from which all sources are relative.
-
-* `sourcesContent`: Optional. An array of contents of the original source files.
-
-* `mappings`: A string of base64 VLQs which contain the actual mappings.
-
-* `file`: Optional. The generated filename this source map is associated with.
-
-The promise of the constructed souce map consumer is returned.
-
-When the `SourceMapConsumer` will no longer be used anymore, you must call its
-`destroy` method.
-
-```js
-const consumer = await new sourceMap.SourceMapConsumer(rawSourceMapJsonData);
-doStuffWith(consumer);
-consumer.destroy();
-```
-
-Alternatively, you can use `SourceMapConsumer.with` to avoid needing to remember
-to call `destroy`.
-
-#### SourceMapConsumer.with
-
-Construct a new `SourceMapConsumer` from `rawSourceMap` and `sourceMapUrl`
-(see the `SourceMapConsumer` constructor for details. Then, invoke the `async
-function f(SourceMapConsumer) -> T` with the newly constructed consumer, wait
-for `f` to complete, call `destroy` on the consumer, and return `f`'s return
-value.
-
-You must not use the consumer after `f` completes!
-
-By using `with`, you do not have to remember to manually call `destroy` on
-the consumer, since it will be called automatically once `f` completes.
-
-```js
-const xSquared = await SourceMapConsumer.with(
-  myRawSourceMap,
-  null,
-  async function (consumer) {
-    // Use `consumer` inside here and don't worry about remembering
-    // to call `destroy`.
-
-    const x = await whatever(consumer);
-    return x * x;
-  }
-);
-
-// You may not use that `consumer` anymore out here; it has
-// been destroyed. But you can use `xSquared`.
-console.log(xSquared);
-```
-
-#### SourceMapConsumer.prototype.destroy()
-
-Free this source map consumer's associated wasm data that is manually-managed.
-
-```js
-consumer.destroy();
-```
-
-Alternatively, you can use `SourceMapConsumer.with` to avoid needing to remember
-to call `destroy`.
-
-#### SourceMapConsumer.prototype.computeColumnSpans()
-
-Compute the last column for each generated mapping. The last column is
-inclusive.
-
-```js
-// Before:
-consumer.allGeneratedPositionsFor({ line: 2, source: "foo.coffee" })
-// [ { line: 2,
-//     column: 1 },
-//   { line: 2,
-//     column: 10 },
-//   { line: 2,
-//     column: 20 } ]
-
-consumer.computeColumnSpans();
-
-// After:
-consumer.allGeneratedPositionsFor({ line: 2, source: "foo.coffee" })
-// [ { line: 2,
-//     column: 1,
-//     lastColumn: 9 },
-//   { line: 2,
-//     column: 10,
-//     lastColumn: 19 },
-//   { line: 2,
-//     column: 20,
-//     lastColumn: Infinity } ]
-```
-
-#### SourceMapConsumer.prototype.originalPositionFor(generatedPosition)
-
-Returns the original source, line, and column information for the generated
-source's line and column positions provided. The only argument is an object with
-the following properties:
-
-* `line`: The line number in the generated source.  Line numbers in
-  this library are 1-based (note that the underlying source map

-
-Returns all generated line and column information for the original source, line,
-and column provided. If no column is provided, returns all mappings
-corresponding to a either the line we are searching for or the next closest line
-that has any mappings. Otherwise, returns all mappings corresponding to the

-```
-
-#### SourceMapConsumer.prototype.hasContentsOfAllSources()
-
-Return true if we have the embedded source content for every source listed in
-the source map, false otherwise.
-
-In other words, if this method returns `true`, then
-`consumer.sourceContentFor(s)` will succeed for every source `s` in
-`consumer.sources`.
-
-```js
-// ...
-if (consumer.hasContentsOfAllSources()) {
-  consumerReadyCallback(consumer);

-  fetchSources(consumer, consumerReadyCallback);
-}
-// ...
-```
-
-#### SourceMapConsumer.prototype.sourceContentFor(source[, returnNullOnMissing])

-  every time that `callback` is called.
-
-* `order`: Either `SourceMapConsumer.GENERATED_ORDER` or
-  `SourceMapConsumer.ORIGINAL_ORDER`. Specifies whether you want to iterate over
-  the mappings sorted by the generated file's line/column order or the
-  original's source/line/column order, respectively. Defaults to
-  `SourceMapConsumer.GENERATED_ORDER`.
-
-```js

-### SourceMapGenerator
-
-An instance of the SourceMapGenerator represents a source map which is being
-built incrementally.
-
-#### new SourceMapGenerator([startOfSourceMap])
-
-You may pass an object with the following properties:
-
-* `file`: The filename of the generated source that this source map is
-  associated with.
-
-* `sourceRoot`: A root for all relative URLs in this source map.
-
-* `skipValidation`: Optional. When `true`, disables validation of mappings as
-  they are added. This can improve performance but should be used with
-  discretion, as a last resort. Even then, one should avoid using this flag when
-  running tests, if possible.
-
-```js
-var generator = new sourceMap.SourceMapGenerator({
-  file: "my-generated-javascript-file.js",
-  sourceRoot: "http://example.com/app/js/"
-});
-```
-
-#### SourceMapGenerator.fromSourceMap(sourceMapConsumer)
-
-Creates a new `SourceMapGenerator` from an existing `SourceMapConsumer` instance.
-
-* `sourceMapConsumer` The SourceMap.
-
-```js
-var generator = sourceMap.SourceMapGenerator.fromSourceMap(consumer);
-```
-
-#### SourceMapGenerator.prototype.addMapping(mapping)
-
-Add a single mapping from original source line and column to the generated
-source's line and column for this source map being created. The mapping object
-should have the following properties:
-
-* `generated`: An object with the generated line and column positions.
-
-* `original`: An object with the original line and column positions.
-
-* `source`: The original source file (relative to the sourceRoot).
-
-* `name`: An optional original token name for this mapping.
-
-```js
-generator.addMapping({
-  source: "module-one.scm",
-  original: { line: 128, column: 0 },
-  generated: { line: 3, column: 456 }
-})
-```
-
-#### SourceMapGenerator.prototype.setSourceContent(sourceFile, sourceContent)
-
-Set the source content for an original source file.
-
-* `sourceFile` the URL of the original source file.
-
-* `sourceContent` the content of the source file.
-
-```js
-generator.setSourceContent("module-one.scm",
-                           fs.readFileSync("path/to/module-one.scm"))
-```
-
-#### SourceMapGenerator.prototype.applySourceMap(sourceMapConsumer[, sourceFile[, sourceMapPath]])
-
-Applies a SourceMap for a source file to the SourceMap.
-Each mapping to the supplied source file is rewritten using the
-supplied SourceMap. Note: The resolution for the resulting mappings
-is the minimum of this map and the supplied map.
-
-* `sourceMapConsumer`: The SourceMap to be applied.
-
-* `sourceFile`: Optional. The filename of the source file.
-  If omitted, sourceMapConsumer.file will be used, if it exists.
-  Otherwise an error will be thrown.
-
-* `sourceMapPath`: Optional. The dirname of the path to the SourceMap
-  to be applied. If relative, it is relative to the SourceMap.
-
-  This parameter is needed when the two SourceMaps aren't in the same
-  directory, and the SourceMap to be applied contains relative source
-  paths. If so, those relative source paths need to be rewritten
-  relative to the SourceMap.
-
-  If omitted, it is assumed that both SourceMaps are in the same directory,
-  thus not needing any rewriting. (Supplying `'.'` has the same effect.)
-
-#### SourceMapGenerator.prototype.toString()
-
-Renders the source map being generated to a string.
-
-```js
-generator.toString()
-// '{"version":3,"sources":["module-one.scm"],"names":[],"mappings":"...snip...","file":"my-generated-javascript-file.js","sourceRoot":"http://example.com/app/js/"}'
-```
-
-### SourceNode
-
-SourceNodes provide a way to abstract over interpolating and/or concatenating
-snippets of generated JavaScript source code, while maintaining the line and
-column information associated between those snippets and the original source
-code. This is useful as the final intermediate representation a compiler might
-use before outputting the generated JS and source map.

-  if it isn't associated with an original column.  The column number
-  is 0-based.
-
-* `source`: The original source's filename; null if no filename is provided.
-
-* `chunk`: Optional. Is immediately passed to `SourceNode.prototype.add`, see
-  below.

-```
-
-#### SourceNode.prototype.walk(fn)

-function is called once for each snippet of JS and is passed that snippet and
-the its original associated source's line/column location.
-
-* `fn`: The traversal function.
-
-```js
-var node = new SourceNode(1, 2, "a.js", [

-c.setSourceContent("c.js", "original c");
-
-var node = new SourceNode(null, null, null, [a, b, c]);
-node.walkSourceContents(function (source, contents) { console.log("WALK:", source, ":", contents); })

-var node = new SourceNode(null, null, null, [ lhs, operand, rhs ]);
-var joinedNode = node.join(" ");
-```
-
-#### SourceNode.prototype.replaceRight(pattern, replacement)

-  "dos",
-  [
-    "tres",
-    new SourceNode(5, 6, "c.js", "quatro")
-  ]
-]);

-/**
- * An IndexedSourceMapConsumer instance represents a parsed source map which
- * we can query for information. It differs from BasicSourceMapConsumer in
- * that it takes "indexed" source maps (i.e. ones with a "sections" field) as
- * input.
- *
- * The first parameter is a raw source map (either as a JSON string, or already
- * parsed to an object). According to the spec for indexed source maps, they
- * have the following attributes:
- *
- *   - version: Which version of the source map spec this map is following.
- *   - file: Optional. The generated file this source map is associated with.
- *   - sections: A list of section definitions.
- *
- * Each value under the "sections" field has two fields:
- *   - offset: The offset into the original specified at which this section
- *       begins to apply, defined as an object with a "line" and "column"
- *       field.
- *   - map: A source map definition. This source map could also be indexed,
- *       but doesn't have to be.
- *
- * Instead of the "map" field, it's also possible to have a "url" field
- * specifying a URL to retrieve a source map from, but that's currently
- * unsupported.
- *
- * Here's an example source map, taken from the source map spec[0], but
- * modified to omit a section which uses the "url" field.
- *
- *  {
- *    version : 3,
- *    file: "app.js",
- *    sections: [{
- *      offset: {line:100, column:10},
- *      map: {
- *        version : 3,
- *        file: "section.js",
- *        sources: ["foo.js", "bar.js"],
- *        names: ["src", "maps", "are", "fun"],
- *        mappings: "AAAA,E;;ABCDE;"
- *      }
- *    }],
- *  }
- *
- * The second parameter, if given, is a string whose value is the URL
- * at which the source map was found.  This URL is used to compute the
- * sources array.

- * Options:
- *
- *    `force`     Always re-compile
- *    `src`       Source directory used to find .styl files,
- *                a string or function accepting `(path)` of request.
- *    `dest`      Destination directory used to output .css files,
- *                a string or function accepting `(path)` of request,
- *                when undefined defaults to `src`.
- *    `compile`   Custom compile function, accepting the arguments
- *                `(str, path)`.
- *    `compress`  Whether the output .css files should be compressed
- *    `firebug`   Emits debug infos in the generated CSS that can
- *                be used by the FireStylus Firebug plugin
- *    `linenos`   Emits comments in the generated CSS indicating
- *                the corresponding Stylus line
- *    'sourcemap' Generates a sourcemap in sourcemaps v3 format
- *
- * Examples:
- *
- * Here we set up the custom compile function so that we may
- * set the `compress` option, or define additional functions.
- *
- * By default the compile function simply sets the `filename`
- * and renders the CSS.

- *          .set('filename', path)
- *          .set('compress', true);
- *      }
- *
- * Pass the middleware to Connect, grabbing .styl files from this directory
- * and saving .css files to _./public_. Also supplying our custom `compile` function.
- *
- * Following that we have a `static()` layer setup to serve the .css
- * files generated by Stylus.
