If this setting is specified then non-relative - * names will be resolved relative to baseUrl: i.e. if baseUrl is '/a/b' then candidate location to resolve module name 'c/d' will - * be '/a/b/c/d' - * - paths - this setting can only be used when baseUrl is specified. allows to tune how non-relative module names - * will be resolved based on the content of the module name. - * Structure of 'paths' compiler options - * 'paths': { - * pattern-1: [...substitutions], - * pattern-2: [...substitutions], - * ... - * pattern-n: [...substitutions] - * } - * Pattern here is a string that can contain zero or one '*' character. During module resolution module name will be matched against - * all patterns in the list. Matching for patterns that don't contain '*' means that module name must be equal to pattern respecting the case. - * If pattern contains '*' then to match pattern "*" module name must start with the and end with . - * denotes part of the module name between and . - * If module name can be matches with multiple patterns then pattern with the longest prefix will be picked. - * After selecting pattern we'll use list of substitutions to get candidate locations of the module and the try to load module - * from the candidate location. - * Substitution is a string that can contain zero or one '*'. To get candidate location from substitution we'll pick every - * substitution in the list and replace '*' with string. If candidate location is not rooted it - * will be converted to absolute using baseUrl. - * For example: - * baseUrl: /a/b/c - * "paths": { - * // match all module names - * "*": [ - * "*", // use matched name as is, - * // will be looked as /a/b/c/ - * - * "folder1/*" // substitution will convert matched name to 'folder1/', - * // since it is not rooted then final candidate location will be /a/b/c/folder1/ - * ], - * // match module names that start with 'components/' - * "components/*": [ "/root/components/*" ] // substitution will convert /components/folder1/ to '/root/components/folder1/', - * // it is rooted so it will be final candidate location - * } - * - * 'rootDirs' allows the project to be spreaded across multiple locations and resolve modules with relative names as if - * they were in the same location. For example lets say there are two files - * '/local/src/content/file1.ts' - * '/shared/components/contracts/src/content/protocols/file2.ts' - * After bundling content of '/shared/components/contracts/src' will be merged with '/local/src' so - * if file1 has the following import 'import {x} from "./protocols/file2"' it will be resolved successfully in runtime. - * 'rootDirs' provides the way to tell compiler that in order to get the whole project it should behave as if content of all - * root dirs were merged together. - * I.e. for the example above 'rootDirs' will have two entries: [ '/local/src', '/shared/components/contracts/src' ]. - * Compiler will first convert './protocols/file2' into absolute path relative to the location of containing file: - * '/local/src/content/protocols/file2' and try to load it - failure. - * Then it will search 'rootDirs' looking for a longest matching prefix of this absolute path and if such prefix is found - absolute path will - * be converted to a path relative to found rootDir entry './content/protocols/file2' (*). As a last step compiler will check all remaining - * entries in 'rootDirs', use them to build absolute path out of (*) and try to resolve module from this location. - */ - function tryLoadModuleUsingOptionalResolutionSettings(extensions, moduleName, containingDirectory, loader, state) { - var resolved = tryLoadModuleUsingPathsIfEligible(extensions, moduleName, loader, state);

Furthermore, the order of iterations is not - * guaranteed, as it is host-dependent. Therefore, when presented with the symbol `foo` from module 'y' alone, we - * may not be sure whether or not it should go in the list. So, we’ll take the following steps: - * - * 1. Resolve alias `foo` from 'y' to the export declaration in 'x', get the symbol there, and see if that symbol is - * already in Bucket A (symbols we already know will be returned). If it is, put `foo` from 'y' in Bucket B - * (symbols that are aliases to symbols in Bucket A). If it’s not, put it in Bucket C. - * 2. Next, imagine we see `foo` from module 'z'. Again, we resolve the alias to the nearest export, which is in 'y'. - * At this point, if that nearest export from 'y' is in _any_ of the three buckets, we know the symbol in 'z' - * should never be returned in the final list, so put it in Bucket B. - * 3. Next, imagine we see `foo` from module 'x', the original. Syntactically, it doesn’t look like a re-export, so - * we can just check Bucket C to see if we put any aliases to the original in there. If they exist, throw them out. - * Put this symbol in Bucket A. - * 4. After we’ve iterated through every symbol of every module, any symbol left in Bucket C means that step 3 didn’t - * occur for that symbol---that is, the original symbol is not in Bucket A, so we should include the alias.

Sometimes it's called a "filter", -// but that's not a great name for it, since that implies a thing where -// some bits pass through, and others are simply ignored. (That would -// be a valid example of a transform, of course.) -// -// While the output is causally related to the input, it's not a -// necessarily symmetric or synchronous transformation. For example, -// a zlib stream might take multiple plain-text writes(), and then -// emit a single compressed chunk some time in the future. -// -// Here's how this works: -// -// The Transform stream has all the aspects of the readable and writable -// stream classes. When you write(chunk), that calls _write(chunk,cb) -// internally, and returns false if there's a lot of pending writes -// buffered up. When you call read(), that calls _read(n) until -// there's enough pending readable data buffered up. -// -// In a transform stream, the written data is placed in a buffer. When -// _read(n) is called, it transforms the queued up data, calling the -// buffered _write cb's as it consumes chunks. If consuming a single -// written chunk would result in multiple output chunks, then the first -// outputted bit calls the readcb, and subsequent chunks just go into -// the read buffer, and will cause it to emit 'readable' if necessary. -// -// This way, back-pressure is actually determined by the reading side, -// since _read has to be called to start processing a new chunk. However, -// a pathological inflate type of transform can cause excessive buffering -// here. For example, imagine a stream where every byte of input is -// interpreted as an integer from 0-255, and then results in that many -// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in -// 1kb of data being output. In this case, you could write a very small -// amount of input, and end up with a very large amount of output. In -// such a pathological inflating mechanism, there'd be no way to tell -// the system to stop doing the transform. A single 4MB write could -// cause the system to run out of memory. -// -// However, even in such a pathological case, only a single written chunk -// would be consumed, and then the rest would wait (un-transformed) until -// the results of the previous transformed chunk were consumed. - - - -module.exports = Transform; - -var Duplex = __webpack_require__(361); -/**/ -var util = Object.create(__webpack_require__(286)); -util.inherits = __webpack_require__(689); -/**/ -util.inherits(Transform, Duplex); +function asyncGeneratorStep(gen, resolve, reject, _next, _throw, key, arg) { try { var info = gen[key](arg); var value = info.value; } catch (error) { reject(error); return; } if (info.done) { resolve(value); } else { Promise.resolve(value).then(_next, _throw); } } -function afterTransform(er, data) { - var ts = this._transformState; - ts.transforming = false; +function _asyncToGenerator(fn) { return function () { var self = this, args = arguments; return new Promise(function (resolve, reject) { var gen = fn.apply(self, args); function _next(value) { asyncGeneratorStep(gen, resolve, reject, _next, _throw, "next", value); } function _throw(err) { asyncGeneratorStep(gen, resolve, reject, _next, _throw, "throw", err); } _next(undefined); }); }; } - var cb = ts.writecb; +function ownKeys(object, enumerableOnly) { var keys = Object.keys(object); if (Object.getOwnPropertySymbols) { var symbols = Object.getOwnPropertySymbols(object); if (enumerableOnly) symbols = symbols.filter(function (sym) { return Object.getOwnPropertyDescriptor(object, sym).enumerable; }); keys.push.apply(keys, symbols); } return keys; } - if (!cb) { - return this.emit('error', new Error('write callback called multiple times')); - } +function _objectSpread(target) { for (var i = 1; i < arguments.length; i++) { var source = arguments[i] != null ?

Sometimes it's called a "filter", +// but that's not a great name for it, since that implies a thing where +// some bits pass through, and others are simply ignored. (That would +// be a valid example of a transform, of course.) +// +// While the output is causally related to the input, it's not a +// necessarily symmetric or synchronous transformation. For example, +// a zlib stream might take multiple plain-text writes(), and then +// emit a single compressed chunk some time in the future. +// +// Here's how this works: +// +// The Transform stream has all the aspects of the readable and writable +// stream classes. When you write(chunk), that calls _write(chunk,cb) +// internally, and returns false if there's a lot of pending writes +// buffered up. When you call read(), that calls _read(n) until +// there's enough pending readable data buffered up. +// +// In a transform stream, the written data is placed in a buffer. When +// _read(n) is called, it transforms the queued up data, calling the +// buffered _write cb's as it consumes chunks. If consuming a single +// written chunk would result in multiple output chunks, then the first +// outputted bit calls the readcb, and subsequent chunks just go into +// the read buffer, and will cause it to emit 'readable' if necessary. +// +// This way, back-pressure is actually determined by the reading side, +// since _read has to be called to start processing a new chunk. However, +// a pathological inflate type of transform can cause excessive buffering +// here. For example, imagine a stream where every byte of input is +// interpreted as an integer from 0-255, and then results in that many +// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in +// 1kb of data being output. In this case, you could write a very small +// amount of input, and end up with a very large amount of output. In +// such a pathological inflating mechanism, there'd be no way to tell +// the system to stop doing the transform. A single 4MB write could +// cause the system to run out of memory. +// +// However, even in such a pathological case, only a single written chunk +// would be consumed, and then the rest would wait (un-transformed) until +// the results of the previous transformed chunk were consumed. - return newNode(type, content, line, column); - } - /** - * @param {Number} i Token's index number - * @returns {Number} - */ - function checkRuleset(i) { - var start = i; - var l = void 0; - if (i >= tokensLength) return 0; +module.exports = Transform; - if (l = checkSelectorsGroup(i)) i += l;else return 0; +var Duplex = __webpack_require__(877); - if (l = checkSC(i)) i += l; +/**/ +var util = Object.create(__webpack_require__(286)); +util.inherits = __webpack_require__(689); +/**/ - if (l = checkBlock(i)) i += l;else return 0; +util.inherits(Transform, Duplex); - return i - start; - } +function afterTransform(er, data) { + var ts = this._transformState; + ts.transforming = false; - function getRuleset() { - var type = NodeType.RulesetType; - var token = tokens[pos]; - var line = token.ln; - var column = token.col; - var content = [].concat(getSelectorsGroup(), getSC(), getBlock()); + var cb = ts.writecb; - return newNode(type, content, line, column); - } + if (!cb) { + return this.emit('error', new Error('write callback called multiple times')); + } - /** - * Check if token is marked as a space (if it's a space or a tab - * or a line break). - * @param {Number} i - * @returns {Number} Number of spaces in a row starting with the given token. - */ - function checkS(i) { - return i < tokensLength && tokens[i].ws ?

Sometimes it's called a "filter", +// but that's not a great name for it, since that implies a thing where +// some bits pass through, and others are simply ignored. (That would +// be a valid example of a transform, of course.) +// +// While the output is causally related to the input, it's not a +// necessarily symmetric or synchronous transformation. For example, +// a zlib stream might take multiple plain-text writes(), and then +// emit a single compressed chunk some time in the future. +// +// Here's how this works: +// +// The Transform stream has all the aspects of the readable and writable +// stream classes. When you write(chunk), that calls _write(chunk,cb) +// internally, and returns false if there's a lot of pending writes +// buffered up. When you call read(), that calls _read(n) until +// there's enough pending readable data buffered up. +// +// In a transform stream, the written data is placed in a buffer. When +// _read(n) is called, it transforms the queued up data, calling the +// buffered _write cb's as it consumes chunks. If consuming a single +// written chunk would result in multiple output chunks, then the first +// outputted bit calls the readcb, and subsequent chunks just go into +// the read buffer, and will cause it to emit 'readable' if necessary. +// +// This way, back-pressure is actually determined by the reading side, +// since _read has to be called to start processing a new chunk. However, +// a pathological inflate type of transform can cause excessive buffering +// here. For example, imagine a stream where every byte of input is +// interpreted as an integer from 0-255, and then results in that many +// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in +// 1kb of data being output. In this case, you could write a very small +// amount of input, and end up with a very large amount of output. In +// such a pathological inflating mechanism, there'd be no way to tell +// the system to stop doing the transform. A single 4MB write could +// cause the system to run out of memory. +// +// However, even in such a pathological case, only a single written chunk +// would be consumed, and then the rest would wait (un-transformed) until +// the results of the previous transformed chunk were consumed. - return i - start; - } - /** - * Get node with a property - * @returns {Array} `['property', x]` - */ - function getProperty3() { - var type = NodeType.PropertyType; - var token = tokens[pos]; - var line = token.ln; - var column = token.col; - var content = [getVariable()]; +module.exports = Transform; - return newNode(type, content, line, column); - } +var _require$codes = __webpack_require__(38).codes, + ERR_METHOD_NOT_IMPLEMENTED = _require$codes.ERR_METHOD_NOT_IMPLEMENTED, + ERR_MULTIPLE_CALLBACK = _require$codes.ERR_MULTIPLE_CALLBACK, + ERR_TRANSFORM_ALREADY_TRANSFORMING = _require$codes.ERR_TRANSFORM_ALREADY_TRANSFORMING, + ERR_TRANSFORM_WITH_LENGTH_0 = _require$codes.ERR_TRANSFORM_WITH_LENGTH_0; - /** - * Check if token is part of a custom property - * @param {Number} i Token's index number - * @return {Number} Length of the property - */ - function checkCustomProperty(i) { - var start = i; - var l = void 0; +var Duplex = __webpack_require__(831); - if (i >= tokensLength) return 0; +__webpack_require__(689)(Transform, Duplex); - if (tokens[i].type !== TokenType.HyphenMinus || tokens[i + 1] && tokens[i + 1].type !== TokenType.HyphenMinus) return 0; +function afterTransform(er, data) { + var ts = this._transformState; + ts.transforming = false; + var cb = ts.writecb; - // Skip `--` - i += 2; + if (cb === null) { + return this.emit('error', new ERR_MULTIPLE_CALLBACK()); + } - if (l = checkIdent(i)) i += l;else return 0; + ts.writechunk = null; + ts.writecb = null; + if (data != null) // single equals check for both `null` and `undefined` + this.push(data); + cb(er); + var rs = this._readableState; + rs.reading = false; - return i - start; - } + if (rs.needReadable || rs.length < rs.highWaterMark) { + this._read(rs.highWaterMark); + } +} - /** - * Get node with a custom property - * @return {Node} - */ - function getCustomProperty() { - var type = NodeType.CustomPropertyType; - var token = tokens[pos]; - var line = token.ln; - var column = token.col; +function Transform(options) { + if (!(this instanceof Transform)) return new Transform(options); + Duplex.call(this, options); + this._transformState = { + afterTransform: afterTransform.bind(this), + needTransform: false, + transforming: false, + writecb: null, + writechunk: null, + writeencoding: null + }; // start out asking for a readable event once data is transformed. - // Skip `--` - pos += 2; + this._readableState.needReadable = true; // we have implemented the _read method, and done the other things + // that Readable wants before the first _read call, so unset the + // sync guard flag. - var content = [getIdent()]; + this._readableState.sync = false; - return newNode(type, content, line, column); - } + if (options) { + if (typeof options.transform === 'function') this._transform = options.transform; + if (typeof options.flush === 'function') this._flush = options.flush; + } // When the writable side finishes, then flush out anything remaining. - /** - * Check if token is a colon - * @param {Number} i Token's index number - * @returns {Number} `1` if token is a colon, otherwise `0` - */ - function checkPropertyDelim(i) { - return i < tokensLength && tokens[i].type === TokenType.Colon ? 1 : 0; - } - /** - * Get node with a colon - * @returns {Array} `['propertyDelim']` - */ - function getPropertyDelim() { - var type = NodeType.PropertyDelimType; - var token = tokens[pos]; - var line = token.ln; - var column = token.col; - var content = ':'; + this.on('prefinish', prefinish); +} - // Skip `:`. - pos++; +function prefinish() { + var _this = this; - return newNode(type, content, line, column); - } + if (typeof this._flush === 'function' && !this._readableState.destroyed) { + this._flush(function (er, data) { + done(_this, er, data); + }); + } else { + done(this, null, null); + } +} - /** - * @param {Number} i Token's index number - * @returns {Number} - */ - function checkPseudo(i) { - return checkPseudoe(i) || checkPseudoc(i); - } +Transform.prototype.push = function (chunk, encoding) { + this._transformState.needTransform = false; + return Duplex.prototype.push.call(this, chunk, encoding); +}; // This is the part where you do stuff! +// override this function in implementation classes. +// 'chunk' is an input chunk. +// +// Call `push(newChunk)` to pass along transformed output +// to the readable side.

Sometimes it's called a "filter", +// but that's not a great name for it, since that implies a thing where +// some bits pass through, and others are simply ignored. (That would +// be a valid example of a transform, of course.) +// +// While the output is causally related to the input, it's not a +// necessarily symmetric or synchronous transformation. For example, +// a zlib stream might take multiple plain-text writes(), and then +// emit a single compressed chunk some time in the future. +// +// Here's how this works: +// +// The Transform stream has all the aspects of the readable and writable +// stream classes. When you write(chunk), that calls _write(chunk,cb) +// internally, and returns false if there's a lot of pending writes +// buffered up. When you call read(), that calls _read(n) until +// there's enough pending readable data buffered up. +// +// In a transform stream, the written data is placed in a buffer. When +// _read(n) is called, it transforms the queued up data, calling the +// buffered _write cb's as it consumes chunks. If consuming a single +// written chunk would result in multiple output chunks, then the first +// outputted bit calls the readcb, and subsequent chunks just go into +// the read buffer, and will cause it to emit 'readable' if necessary. +// +// This way, back-pressure is actually determined by the reading side, +// since _read has to be called to start processing a new chunk. However, +// a pathological inflate type of transform can cause excessive buffering +// here. For example, imagine a stream where every byte of input is +// interpreted as an integer from 0-255, and then results in that many +// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in +// 1kb of data being output. In this case, you could write a very small +// amount of input, and end up with a very large amount of output. In +// such a pathological inflating mechanism, there'd be no way to tell +// the system to stop doing the transform. A single 4MB write could +// cause the system to run out of memory. +// +// However, even in such a pathological case, only a single written chunk +// would be consumed, and then the rest would wait (un-transformed) until +// the results of the previous transformed chunk were consumed. - content.push(getNamespacePrefix()); - if (checkCommentML(pos)) content.push(getCommentML()); - content.push(getNamespaceSeparator()); +module.exports = Transform; - return newNode(type, content, line, column); - } +var Duplex = __webpack_require__(959); - /** - * (1) `|` - */ - function checkNamePrefix2(i) { - return checkNamespaceSeparator(i); - } +/**/ +var util = Object.create(__webpack_require__(286)); +util.inherits = __webpack_require__(689); +/**/ - function getNamePrefix2() { - var type = NodeType.NamePrefixType; - var token = tokens[pos]; - var line = token.ln; - var column = token.col; - var content = [getNamespaceSeparator()]; +util.inherits(Transform, Duplex); - return newNode(type, content, line, column); - } +function afterTransform(er, data) { + var ts = this._transformState; + ts.transforming = false; - /** - * (1) `*` - * (2) `panda` - */ - function checkNamespacePrefix(i) { - if (i >= tokensLength) return 0; + var cb = ts.writecb; - var l = void 0; + if (!cb) { + return this.emit('error', new Error('write callback called multiple times')); + } - if (tokens[i].type === TokenType.Asterisk) return 1;else if (l = checkIdentOrInterpolation(i)) return l;else return 0; - } + ts.writechunk = null; + ts.writecb = null; - function getNamespacePrefix() { - var type = NodeType.NamespacePrefixType; - var token = tokens[pos]; - var line = token.ln; - var column = token.col; - var content = []; + if (data != null) // single equals check for both `null` and `undefined` + this.push(data); - if (token.type === TokenType.Asterisk) { - var asteriskNode = newNode(NodeType.IdentType, '*', line, column); - content.push(asteriskNode); - pos++; - } else if (checkIdentOrInterpolation(pos)) content = content.concat(getIdentOrInterpolation()); + cb(er); - return newNode(type, content, line, column); - } + var rs = this._readableState; + rs.reading = false; + if (rs.needReadable || rs.length < rs.highWaterMark) { + this._read(rs.highWaterMark); + } +} - /** - * (1) `|` - */ - function checkNamespaceSeparator(i) { - if (i >= tokensLength) return 0; +function Transform(options) { + if (!(this instanceof Transform)) return new Transform(options); - if (tokens[i].type !== TokenType.VerticalLine) return 0; + Duplex.call(this, options); - // Return false if `|=` - [attr|=value] - if (tokens[i + 1] && tokens[i + 1].type === TokenType.EqualsSign) return 0; + this._transformState = { + afterTransform: afterTransform.bind(this), + needTransform: false, + transforming: false, + writecb: null, + writechunk: null, + writeencoding: null + }; - return 1; - } + // start out asking for a readable event once data is transformed. + this._readableState.needReadable = true; - function getNamespaceSeparator() { - var type = NodeType.NamespaceSeparatorType; - var token = tokens[pos]; - var line = token.ln; - var column = token.col; - var content = '|'; + // we have implemented the _read method, and done the other things + // that Readable wants before the first _read call, so unset the + // sync guard flag. + this._readableState.sync = false; - pos++; - return newNode(type, content, line, column); - } + if (options) { + if (typeof options.transform === 'function') this._transform = options.transform; - module.exports = function (_tokens, context) { - tokens = _tokens; - tokensLength = tokens.length; - pos = 0; + if (typeof options.flush === 'function') this._flush = options.flush; + } - return contexts[context](); - }; + // When the writable side finishes, then flush out anything remaining. + this.on('prefinish', prefinish); +} -/***/ }), -/* 28 */ -/***/ (function(module, exports, __nested_webpack_require_550779__) { +function prefinish() { + var _this = this; - 'use strict'; + if (typeof this._flush === 'function') { + this._flush(function (er, data) { + done(_this, er, data); + }); + } else { + done(this, null, null); + } +} - module.exports = function (css, tabSize) { - var TokenType = __nested_webpack_require_550779__(13); +Transform.prototype.push = function (chunk, encoding) { + this._transformState.needTransform = false; + return Duplex.prototype.push.call(this, chunk, encoding); +}; - var tokens = []; - var urlMode = false; - var c = void 0; // Current character - var cn = void 0; // Next character - var pos = 0; - var tn = 0; - var ln = 1; - var col = 1; +// This is the part where you do stuff! +// override this function in implementation classes. +// 'chunk' is an input chunk. +// +// Call `push(newChunk)` to pass along transformed output +// to the readable side.

The function receives one or two arguments: - * * a `results` object, containing the results of the previously executed - * functions, only passed if the task has any dependencies, - * * a `callback(err, result)` function, which must be called when finished, - * passing an `error` (which can be `null`) and the result of the function's - * execution. - * @param {number} [concurrency=Infinity] - An optional `integer` for - * determining the maximum number of tasks that can be run in parallel. By - * default, as many as possible. - * @param {Function} [callback] - An optional callback which is called when all - * the tasks have been completed. It receives the `err` argument if any `tasks` - * pass an error to their callback. Results are always returned; however, if an - * error occurs, no further `tasks` will be performed, and the results object - * will only contain partial results. Invoked with (err, results). - * @returns undefined - * @example - * - * async.auto({ - * // this function will just be passed a callback - * readData: async.apply(fs.readFile, 'data.txt', 'utf-8'), - * showData: ['readData', function(results, cb) { - * // results.readData is the file's contents - * // ... - * }] - * }, callback); - * - * async.auto({ - * get_data: function(callback) { - * console.log('in get_data'); - * // async code to get some data - * callback(null, 'data', 'converted to array'); - * }, - * make_folder: function(callback) { - * console.log('in make_folder'); - * // async code to create a directory to store a file in - * // this is run at the same time as getting the data - * callback(null, 'folder'); - * }, - * write_file: ['get_data', 'make_folder', function(results, callback) { - * console.log('in write_file', JSON.stringify(results)); - * // once there is some data and the directory exists, - * // write the data to a file in the directory - * callback(null, 'filename'); - * }], - * email_link: ['write_file', function(results, callback) { - * console.log('in email_link', JSON.stringify(results)); - * // once the file is written let's email a link to it... - * // results.write_file contains the filename returned by write_file. - * callback(null, {'file':results.write_file, 'email':'user@example.com'}); - * }] - * }, function(err, results) { - * console.log('err = ', err); - * console.log('results = ', results); - * }); - */ -var auto = function (tasks, concurrency, callback) { - if (typeof concurrency === 'function') { - // concurrency is optional, shift the args. - callback = concurrency; - concurrency = null; - } - callback = once(callback || noop); - var keys$$1 = keys(tasks); - var numTasks = keys$$1.length; - if (!numTasks) { - return callback(null); - } - if (!concurrency) { - concurrency = numTasks; +class Node { + constructor(parser, pos, loc) { + this.type = ""; + this.start = pos; + this.end = 0; + this.loc = new SourceLocation(loc); + if (parser && parser.options.ranges) this.range = [pos, 0]; + if (parser && parser.filename) this.loc.filename = parser.filename; + } + + __clone() { + const newNode = new Node(); + const keys = Object.keys(this); + + for (let i = 0, length = keys.length; i < length; i++) { + const key = keys[i]; + + if (key !== "leadingComments" && key !== "trailingComments" && key !== "innerComments") { + newNode[key] = this[key]; + } } - var results = {}; - var runningTasks = 0; - var hasError = false; + return newNode; + } - var listeners = Object.create(null); +} - var readyTasks = []; +class NodeUtils extends UtilParser { + startNode() { + return new Node(this, this.state.start, this.state.startLoc); + } - // for cycle detection: - var readyToCheck = []; // tasks that have been identified as reachable - // without the possibility of returning to an ancestor task - var uncheckedDependencies = {}; + startNodeAt(pos, loc) { + return new Node(this, pos, loc); + } - baseForOwn(tasks, function (task, key) { - if (!isArray(task)) { - // no dependencies - enqueueTask(key, [task]); - readyToCheck.push(key); - return; - } + startNodeAtNode(type) { + return this.startNodeAt(type.start, type.loc.start); + } - var dependencies = task.slice(0, task.length - 1); - var remainingDependencies = dependencies.length; - if (remainingDependencies === 0) { - enqueueTask(key, task); - readyToCheck.push(key); - return; - } - uncheckedDependencies[key] = remainingDependencies; + finishNode(node, type) { + return this.finishNodeAt(node, type, this.state.lastTokEnd, this.state.lastTokEndLoc); + } - arrayEach(dependencies, function (dependencyName) { - if (!tasks[dependencyName]) { - throw new Error('async.auto task `' + key + - '` has a non-existent dependency `' + - dependencyName + '` in ' + - dependencies.join(', ')); - } - addListener(dependencyName, function () { - remainingDependencies--; - if (remainingDependencies === 0) { - enqueueTask(key, task); - } - }); - }); - }); + finishNodeAt(node, type, pos, loc) { - checkForDeadlocks(); - processQueue(); + node.type = type; + node.end = pos; + node.loc.end = loc; + if (this.options.ranges) node.range[1] = pos; + this.processComment(node); + return node; + } - function enqueueTask(key, task) { - readyTasks.push(function () { - runTask(key, task); - }); + resetStartLocation(node, start, startLoc) { + node.start = start; + node.loc.start = startLoc; + if (this.options.ranges) node.range[0] = start; + } + + resetEndLocation(node, end = this.state.lastTokEnd, endLoc = this.state.lastTokEndLoc) { + node.end = end; + node.loc.end = endLoc; + if (this.options.ranges) node.range[1] = end; + } + + resetStartLocationFromNode(node, locationNode) { + this.resetStartLocation(node, locationNode.start, locationNode.loc.start); + } + +} + +const unwrapParenthesizedExpression = node => { + return node.type === "ParenthesizedExpression" ?

It receives the `err` argument if any `tasks` - * pass an error to their callback, and a `results` object with any completed - * task results, similar to `auto`. - * @example - * - * // The example from `auto` can be rewritten as follows: - * async.autoInject({ - * get_data: function(callback) { - * // async code to get some data - * callback(null, 'data', 'converted to array'); - * }, - * make_folder: function(callback) { - * // async code to create a directory to store a file in - * // this is run at the same time as getting the data - * callback(null, 'folder'); - * }, - * write_file: function(get_data, make_folder, callback) { - * // once there is some data and the directory exists, - * // write the data to a file in the directory - * callback(null, 'filename'); - * }, - * email_link: function(write_file, callback) { - * // once the file is written let's email a link to it... - * // write_file contains the filename returned by write_file. - * callback(null, {'file':write_file, 'email':'user@example.com'}); - * } - * }, function(err, results) { - * console.log('err = ', err); - * console.log('email_link = ', results.email_link); - * }); - * - * // If you are using a JS minifier that mangles parameter names, `autoInject` - * // will not work with plain functions, since the parameter names will be - * // collapsed to a single letter identifier.

Sometimes it's called a "filter", -// but that's not a great name for it, since that implies a thing where -// some bits pass through, and others are simply ignored. (That would -// be a valid example of a transform, of course.) -// -// While the output is causally related to the input, it's not a -// necessarily symmetric or synchronous transformation. For example, -// a zlib stream might take multiple plain-text writes(), and then -// emit a single compressed chunk some time in the future. -// -// Here's how this works: -// -// The Transform stream has all the aspects of the readable and writable -// stream classes. When you write(chunk), that calls _write(chunk,cb) -// internally, and returns false if there's a lot of pending writes -// buffered up. When you call read(), that calls _read(n) until -// there's enough pending readable data buffered up. -// -// In a transform stream, the written data is placed in a buffer. When -// _read(n) is called, it transforms the queued up data, calling the -// buffered _write cb's as it consumes chunks. If consuming a single -// written chunk would result in multiple output chunks, then the first -// outputted bit calls the readcb, and subsequent chunks just go into -// the read buffer, and will cause it to emit 'readable' if necessary. -// -// This way, back-pressure is actually determined by the reading side, -// since _read has to be called to start processing a new chunk. However, -// a pathological inflate type of transform can cause excessive buffering -// here. For example, imagine a stream where every byte of input is -// interpreted as an integer from 0-255, and then results in that many -// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in -// 1kb of data being output. In this case, you could write a very small -// amount of input, and end up with a very large amount of output. In -// such a pathological inflating mechanism, there'd be no way to tell -// the system to stop doing the transform. A single 4MB write could -// cause the system to run out of memory. -// -// However, even in such a pathological case, only a single written chunk -// would be consumed, and then the rest would wait (un-transformed) until -// the results of the previous transformed chunk were consumed. +var _stringify2 = _interopRequireDefault(__webpack_require__(880)); +var _warnOnce = _interopRequireDefault(__webpack_require__(666)); +var _result = _interopRequireDefault(__webpack_require__(585)); -module.exports = Transform; +var _parse = _interopRequireDefault(__webpack_require__(439)); -var Duplex = __webpack_require__(877); +function _interopRequireDefault(obj) { return obj && obj.__esModule ? obj : { default: obj }; } -/**/ -var util = Object.create(__webpack_require__(286)); -util.inherits = __webpack_require__(689); -/**/ +function _defineProperties(target, props) { for (var i = 0; i < props.length; i++) { var descriptor = props[i]; descriptor.enumerable = descriptor.enumerable || false; descriptor.configurable = true; if ("value" in descriptor) descriptor.writable = true; Object.defineProperty(target, descriptor.key, descriptor); } } -util.inherits(Transform, Duplex); +function _createClass(Constructor, protoProps, staticProps) { if (protoProps) _defineProperties(Constructor.prototype, protoProps); if (staticProps) _defineProperties(Constructor, staticProps); return Constructor; } -function afterTransform(er, data) { - var ts = this._transformState; - ts.transforming = false; +function isPromise(obj) { + return typeof obj === 'object' && typeof obj.then === 'function'; +} +/** + * A Promise proxy for the result of PostCSS transformations. + * + * A `LazyResult` instance is returned by {@link Processor#process}. + * + * @example + * const lazy = postcss([autoprefixer]).process(css) + */ - var cb = ts.writecb; - if (!cb) { - return this.emit('error', new Error('write callback called multiple times')); +var LazyResult = +/*#__PURE__*/ +function () { + function LazyResult(processor, css, opts) { + this.stringified = false; + this.processed = false; + var root; + + if (typeof css === 'object' && css !== null && css.type === 'root') { + root = css; + } else if (css instanceof LazyResult || css instanceof _result.default) { + root = css.root; + + if (css.map) { + if (typeof opts.map === 'undefined') opts.map = {}; + if (!opts.map.inline) opts.map.inline = false; + opts.map.prev = css.map; + } + } else { + var parser = _parse.default; + if (opts.syntax) parser = opts.syntax.parse; + if (opts.parser) parser = opts.parser; + if (parser.parse) parser = parser.parse; + + try { + root = parser(css, opts); + } catch (error) { + this.error = error; + } + } + + this.result = new _result.default(processor, root, opts); } + /** + * Returns a {@link Processor} instance, which will be used + * for CSS transformations. + * + * @type {Processor} + */ - ts.writechunk = null; - ts.writecb = null; - if (data != null) // single equals check for both `null` and `undefined` - this.push(data); + var _proto = LazyResult.prototype; - cb(er); + /** + * Processes input CSS through synchronous plugins + * and calls {@link Result#warnings()}. + * + * @return {Warning[]} Warnings from plugins. + */ + _proto.warnings = function warnings() { + return this.sync().warnings(); + } + /** + * Alias for the {@link LazyResult#css} property. + * + * @example + * lazy + '' === lazy.css + * + * @return {string} Output CSS. + */ + ; - var rs = this._readableState; - rs.reading = false; - if (rs.needReadable || rs.length < rs.highWaterMark) { - this._read(rs.highWaterMark); + _proto.toString = function toString() { + return this.css; } -} + /** + * Processes input CSS through synchronous and asynchronous plugins + * and calls `onFulfilled` with a Result instance.

Sometimes it's called a "filter", +// but that's not a great name for it, since that implies a thing where +// some bits pass through, and others are simply ignored. (That would +// be a valid example of a transform, of course.) +// +// While the output is causally related to the input, it's not a +// necessarily symmetric or synchronous transformation. For example, +// a zlib stream might take multiple plain-text writes(), and then +// emit a single compressed chunk some time in the future. +// +// Here's how this works: +// +// The Transform stream has all the aspects of the readable and writable +// stream classes. When you write(chunk), that calls _write(chunk,cb) +// internally, and returns false if there's a lot of pending writes +// buffered up. When you call read(), that calls _read(n) until +// there's enough pending readable data buffered up. +// +// In a transform stream, the written data is placed in a buffer. When +// _read(n) is called, it transforms the queued up data, calling the +// buffered _write cb's as it consumes chunks. If consuming a single +// written chunk would result in multiple output chunks, then the first +// outputted bit calls the readcb, and subsequent chunks just go into +// the read buffer, and will cause it to emit 'readable' if necessary. +// +// This way, back-pressure is actually determined by the reading side, +// since _read has to be called to start processing a new chunk. However, +// a pathological inflate type of transform can cause excessive buffering +// here. For example, imagine a stream where every byte of input is +// interpreted as an integer from 0-255, and then results in that many +// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in +// 1kb of data being output. In this case, you could write a very small +// amount of input, and end up with a very large amount of output. In +// such a pathological inflating mechanism, there'd be no way to tell +// the system to stop doing the transform. A single 4MB write could +// cause the system to run out of memory. +// +// However, even in such a pathological case, only a single written chunk +// would be consumed, and then the rest would wait (un-transformed) until +// the results of the previous transformed chunk were consumed. -/**/ -var pna = __webpack_require__(822);

Sometimes it's called a "filter", -// but that's not a great name for it, since that implies a thing where -// some bits pass through, and others are simply ignored. (That would -// be a valid example of a transform, of course.) -// -// While the output is causally related to the input, it's not a -// necessarily symmetric or synchronous transformation. For example, -// a zlib stream might take multiple plain-text writes(), and then -// emit a single compressed chunk some time in the future. -// -// Here's how this works: -// -// The Transform stream has all the aspects of the readable and writable -// stream classes. When you write(chunk), that calls _write(chunk,cb) -// internally, and returns false if there's a lot of pending writes -// buffered up. When you call read(), that calls _read(n) until -// there's enough pending readable data buffered up. -// -// In a transform stream, the written data is placed in a buffer. When -// _read(n) is called, it transforms the queued up data, calling the -// buffered _write cb's as it consumes chunks. If consuming a single -// written chunk would result in multiple output chunks, then the first -// outputted bit calls the readcb, and subsequent chunks just go into -// the read buffer, and will cause it to emit 'readable' if necessary. -// -// This way, back-pressure is actually determined by the reading side, -// since _read has to be called to start processing a new chunk. However, -// a pathological inflate type of transform can cause excessive buffering -// here. For example, imagine a stream where every byte of input is -// interpreted as an integer from 0-255, and then results in that many -// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in -// 1kb of data being output. In this case, you could write a very small -// amount of input, and end up with a very large amount of output. In -// such a pathological inflating mechanism, there'd be no way to tell -// the system to stop doing the transform. A single 4MB write could -// cause the system to run out of memory. -// -// However, even in such a pathological case, only a single written chunk -// would be consumed, and then the rest would wait (un-transformed) until -// the results of the previous transformed chunk were consumed. - - -module.exports = Transform; - -var _require$codes = __webpack_require__(38).codes, - ERR_METHOD_NOT_IMPLEMENTED = _require$codes.ERR_METHOD_NOT_IMPLEMENTED, - ERR_MULTIPLE_CALLBACK = _require$codes.ERR_MULTIPLE_CALLBACK, - ERR_TRANSFORM_ALREADY_TRANSFORMING = _require$codes.ERR_TRANSFORM_ALREADY_TRANSFORMING, - ERR_TRANSFORM_WITH_LENGTH_0 = _require$codes.ERR_TRANSFORM_WITH_LENGTH_0; - -var Duplex = __webpack_require__(831); - -__webpack_require__(689)(Transform, Duplex); - -function afterTransform(er, data) { - var ts = this._transformState; - ts.transforming = false; - var cb = ts.writecb; - - if (cb === null) { - return this.emit('error', new ERR_MULTIPLE_CALLBACK()); - } - - ts.writechunk = null; - ts.writecb = null; - if (data != null) // single equals check for both `null` and `undefined` - this.push(data); - cb(er); - var rs = this._readableState; - rs.reading = false; - - if (rs.needReadable || rs.length < rs.highWaterMark) { - this._read(rs.highWaterMark); - } -} - -function Transform(options) { - if (!(this instanceof Transform)) return new Transform(options); - Duplex.call(this, options); - this._transformState = { - afterTransform: afterTransform.bind(this), - needTransform: false, - transforming: false, - writecb: null, - writechunk: null, - writeencoding: null - }; // start out asking for a readable event once data is transformed. - - this._readableState.needReadable = true; // we have implemented the _read method, and done the other things - // that Readable wants before the first _read call, so unset the - // sync guard flag. - - this._readableState.sync = false; - - if (options) { - if (typeof options.transform === 'function') this._transform = options.transform; - if (typeof options.flush === 'function') this._flush = options.flush; - } // When the writable side finishes, then flush out anything remaining. - - - this.on('prefinish', prefinish); -} - -function prefinish() { - var _this = this; - - if (typeof this._flush === 'function' && !this._readableState.destroyed) { - this._flush(function (er, data) { - done(_this, er, data); - }); - } else { - done(this, null, null); - } -} - -Transform.prototype.push = function (chunk, encoding) { - this._transformState.needTransform = false; - return Duplex.prototype.push.call(this, chunk, encoding); -}; // This is the part where you do stuff! -// override this function in implementation classes. -// 'chunk' is an input chunk. -// -// Call `push(newChunk)` to pass along transformed output -// to the readable side.

Sometimes it's called a "filter", -// but that's not a great name for it, since that implies a thing where -// some bits pass through, and others are simply ignored. (That would -// be a valid example of a transform, of course.) -// -// While the output is causally related to the input, it's not a -// necessarily symmetric or synchronous transformation. For example, -// a zlib stream might take multiple plain-text writes(), and then -// emit a single compressed chunk some time in the future. -// -// Here's how this works: -// -// The Transform stream has all the aspects of the readable and writable -// stream classes. When you write(chunk), that calls _write(chunk,cb) -// internally, and returns false if there's a lot of pending writes -// buffered up. When you call read(), that calls _read(n) until -// there's enough pending readable data buffered up. -// -// In a transform stream, the written data is placed in a buffer. When -// _read(n) is called, it transforms the queued up data, calling the -// buffered _write cb's as it consumes chunks. If consuming a single -// written chunk would result in multiple output chunks, then the first -// outputted bit calls the readcb, and subsequent chunks just go into -// the read buffer, and will cause it to emit 'readable' if necessary. -// -// This way, back-pressure is actually determined by the reading side, -// since _read has to be called to start processing a new chunk. However, -// a pathological inflate type of transform can cause excessive buffering -// here. For example, imagine a stream where every byte of input is -// interpreted as an integer from 0-255, and then results in that many -// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in -// 1kb of data being output. In this case, you could write a very small -// amount of input, and end up with a very large amount of output. In -// such a pathological inflating mechanism, there'd be no way to tell -// the system to stop doing the transform. A single 4MB write could -// cause the system to run out of memory. -// -// However, even in such a pathological case, only a single written chunk -// would be consumed, and then the rest would wait (un-transformed) until -// the results of the previous transformed chunk were consumed. - - - -module.exports = Transform; - -var Duplex = __webpack_require__(959); - -/**/ -var util = Object.create(__webpack_require__(286)); -util.inherits = __webpack_require__(689); -/**/ - -util.inherits(Transform, Duplex); - -function afterTransform(er, data) { - var ts = this._transformState; - ts.transforming = false; - - var cb = ts.writecb; - - if (!cb) { - return this.emit('error', new Error('write callback called multiple times')); - } - - ts.writechunk = null; - ts.writecb = null; - - if (data != null) // single equals check for both `null` and `undefined` - this.push(data); - - cb(er); - - var rs = this._readableState; - rs.reading = false; - if (rs.needReadable || rs.length < rs.highWaterMark) { - this._read(rs.highWaterMark); - } -} - -function Transform(options) { - if (!(this instanceof Transform)) return new Transform(options); - - Duplex.call(this, options); - - this._transformState = { - afterTransform: afterTransform.bind(this), - needTransform: false, - transforming: false, - writecb: null, - writechunk: null, - writeencoding: null - }; - - // start out asking for a readable event once data is transformed. - this._readableState.needReadable = true; - - // we have implemented the _read method, and done the other things - // that Readable wants before the first _read call, so unset the - // sync guard flag. - this._readableState.sync = false; - - if (options) { - if (typeof options.transform === 'function') this._transform = options.transform; - - if (typeof options.flush === 'function') this._flush = options.flush; - } - - // When the writable side finishes, then flush out anything remaining. - this.on('prefinish', prefinish); -} - -function prefinish() { - var _this = this; - - if (typeof this._flush === 'function') { - this._flush(function (er, data) { - done(_this, er, data); - }); - } else { - done(this, null, null); - } -} - -Transform.prototype.push = function (chunk, encoding) { - this._transformState.needTransform = false; - return Duplex.prototype.push.call(this, chunk, encoding); -}; - -// This is the part where you do stuff! -// override this function in implementation classes. -// 'chunk' is an input chunk. -// -// Call `push(newChunk)` to pass along transformed output -// to the readable side.
