+
+# CSS Declaration Sorter
+[![npm][npm-badge]][npm]
+
+A Node.js module and [PostCSS] plugin to sort CSS, SCSS or Less declarations based on their property names. Ensuring styling is organized, more consistent and in order... The goal of this package is to sort the source code of a project in the build process or to decrease the distributed CSS gzipped size.
+
+Check out [the Prettier plugin](https://github.com/Siilwyn/prettier-plugin-css-order) for usage with a variety of file formats.
+
+## Niceness
+- Up-to-date CSS properties fetched from the [MDN Compatibility Data](https://github.com/mdn/browser-compat-data/) project.
+- Choose your wanted order or provide your own.
+- Nested rules sorting support.
+- SCSS and Less support when combined with either [postcss-scss](https://github.com/postcss/postcss-scss) or [postcss-less](https://github.com/webschik/postcss-less).
+- Thought-out sorting orders out of the box, **approved by their authors**.
+
+## Alphabetical example
+Input:
+```css
+body {
+    display: block;
+    animation: none;
+    color: #C55;
+    border: 0;
+}
+```
+
+Output:
+```css
+body {
+    animation: none;
+    border: 0;
+    color: #C55;
+    display: block;
+}
+```
+
+## Built-in sorting orders
+- Alphabetical  
+`alphabetical`  
+*Default, order in a simple alphabetical manner from a - z.*
+
+- [SMACSS](http://smacss.com/book/formatting#grouping)  
+`smacss`  
+*Order from most important, flow affecting properties, to least important properties.*
+  1. Box
+  2. Border
+  3. Background
+  4. Text
+  5. Other
+
+- [Concentric CSS](https://github.com/brandon-rhodes/Concentric-CSS)  
+`concentric-css`  
+*Order properties applying outside the box model, moving inward to intrinsic changes.*
+  1. Positioning
+  2. Visibility
+  3. Box model
+  4. Dimensions
+  5. Text
+
+## Usage
+Following the PostCSS plugin guidelines, this package depends on PostCSS as a peer dependency:  
+`npm install postcss css-declaration-sorter --save-dev`
+
+### CLI
+This module does not include its own CLI but works with the official [PostCSS CLI](https://github.com/postcss/postcss-cli). To use the examples below, the `postcss-cli` package is a required dependency.
+
+Piping out result from file:  
+`postcss input.css --use css-declaration-sorter | cat`
+
+Sorting multiple files by overwriting:  
+`postcss *.css --use css-declaration-sorter --replace --no-map`
+
+Sorting all files in a directory with SCSS syntax using [postcss-scss](https://github.com/postcss/postcss-scss) by overwriting:  
+`postcss ./src/**/*.scss --syntax postcss-scss --use css-declaration-sorter --replace --no-map`
+
+Sorting all files in the directory with SCSS syntax and SMACSS order by overwriting, using `package.json` configuration:  
+```json
+"postcss": {
+  "syntax": "postcss-scss",
+  "map": false,
+  "plugins": {
+    "css-declaration-sorter": { "order": "smacss" }
+  }
+}
+```
+
+`postcss ./src/**/*.scss --replace --config package.json`
+
+### Vanilla JS
+```js
+import postcss from 'postcss';
+import { cssDeclarationSorter } from 'css-declaration-sorter';
+
+postcss([cssDeclarationSorter({ order: 'smacss' })])
+  .process('a { color: hyperblue; display: block; }', { from: undefined })
+  .then(result => console.log(
+    result.css === 'a { display: block; color: hyperblue; }'
+  ));
+```

+
+## API
+### cssDeclarationSorter({ order, keepOverrides })
+
+#### order
+Type: `string` or `function`  
+Default: `alphabetical`  
+Options: `alphabetical`, `smacss`, `concentric-css`
+
+Provide the name of one of the built-in sort orders or a comparison function that is passed to ([`Array.sort`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/sort)). This function receives two declaration names and is expected to return `-1`, `0` or `1` depending on the wanted order.
+
+#### keepOverrides
+Type: `Boolean`  
+Default: `false`  
+
+To prevent breaking legacy CSS where shorthand declarations override longhand declarations (also taking into account vendor prefixes) this option can enabled. For example `animation-name: some; animation: greeting;` will be kept in this order when `keepOverrides` is `true`.

+
+A CSS selector compiler and engine
+
+## What?
+
+As a **compiler**, css-select turns CSS selectors into functions that tests if
+elements match them.
+
+As an **engine**, css-select looks through a DOM tree, searching for elements.
+Elements are tested "from the top", similar to how browsers execute CSS
+selectors.
+
+In its default configuration, css-select queries the DOM structure of the
+[`domhandler`](https://github.com/fb55/domhandler) module (also known as
+htmlparser2 DOM). To query alternative DOM structures, see [`Options`](#options)
+below.
+
+**Features:**
+
+-   🔬 Full implementation of CSS3 selectors, as well as most CSS4 selectors
+-   🧪 Partial implementation of jQuery/Sizzle extensions (see
+    [cheerio-select](https://github.com/cheeriojs/cheerio-select) for the
+    remaining selectors)
+-   🧑‍🔬 High test coverage, including the full test suites from Sizzle, Qwery and
+    NWMatcher.
+-   🥼 Reliably great performance
+
+## Why?
+
+Most CSS engines written in JavaScript execute selectors left-to-right. That
+means thet execute every component of the selector in order, from left to right
+_(duh)_. As an example: For the selector `a b`, these engines will first query
+for `a` elements, then search these for `b` elements. (That's the approach of
+eg. [`Sizzle`](https://github.com/jquery/sizzle),
+[`nwmatcher`](https://github.com/dperini/nwmatcher/) and
+[`qwery`](https://github.com/ded/qwery).)
+
+While this works, it has some downsides: Children of `a`s will be checked
+multiple times; first, to check if they are also `a`s, then, for every superior
+`a` once, if they are `b`s. Using
+[Big O notation](http://en.wikipedia.org/wiki/Big_O_notation), that would be
+`O(n^(k+1))`, where `k` is the number of descendant selectors (that's the space
+in the example above).
+
+The far more efficient approach is to first look for `b` elements, then check if
+they have superior `a` elements: Using big O notation again, that would be
+`O(n)`. That's called right-to-left execution.
+
+And that's what css-select does – and why it's quite performant.
+
+## How does it work?
+
+By building a stack of functions.
+
+_Wait, what?_
+
+Okay, so let's suppose we want to compile the selector `a b`, for right-to-left
+execution. We start by _parsing_ the selector. This turns the selector into an
+array of the building blocks. That's what the
+[`css-what`](https://github.com/fb55/css-what) module is for, if you want to
+have a look.
+
+Anyway, after parsing, we end up with an array like this one:
+
+```js
+[
+    { type: "tag", name: "a" },
+    { type: "descendant" },
+    { type: "tag", name: "b" },
+];
+```
+
+(Actually, this array is wrapped in another array, but that's another story,
+involving commas in selectors.)
+
+Now that we know the meaning of every part of the selector, we can compile it.
+That is where things become interesting.
+
+The basic idea is to turn every part of the selector into a function, which
+takes an element as its only argument. The function checks whether a passed
+element matches its part of the selector: If it does, the element is passed to
+the next function representing the next part of the selector. That function does
+the same. If an element is accepted by all parts of the selector, it _matches_
+the selector and double rainbow ALL THE WAY.
+
+As said before, we want to do right-to-left execution with all the big O
+improvements. That means elements are passed from the rightmost part of the
+selector (`b` in our example) to the leftmost (~~which would be `c`~~ of course
+`a`).
+
+For traversals, such as the _descendant_ operating the space between `a` and
+`b`, we walk up the DOM tree, starting from the element passed as argument.
+
+_//TODO: More in-depth description. Implementation details. Build a spaceship._
+
+## API
+
+```js
+const CSSselect = require("css-select");
+```
+
+**Note:** css-select throws errors when invalid selectors are passed to it.This
+is done to aid with writing css selectors, but can be unexpected when processing
+arbitrary strings.
+
+#### `CSSselect.selectAll(query, elems, options)`
+
+Queries `elems`, returns an array containing all matches.
+
+-   `query` can be either a CSS selector or a function.
+-   `elems` can be either an array of elements, or a single element. If it is an
+    element, its children will be queried.
+-   `options` is described below.
+
+Aliases: `default` export, `CSSselect.iterate(query, elems)`.
+
+#### `CSSselect.compile(query, options)`
+
+Compiles the query, returns a function.
+
+#### `CSSselect.is(elem, query, options)`
+
+Tests whether or not an element is matched by `query`. `query` can be either a
+CSS selector or a function.
+
+#### `CSSselect.selectOne(query, elems, options)`
+
+Arguments are the same as for `CSSselect.selectAll(query, elems)`. Only returns
+the first match, or `null` if there was no match.
+
+### Options
+
+All options are optional.
+
+-   `xmlMode`: When enabled, tag names will be case-sensitive. Default: `false`.
+-   `rootFunc`: The last function in the stack, will be called with the last
+    element that's looked at.
+-   `adapter`: The adapter to use when interacting with the backing DOM
+    structure. By default it uses the `domutils` module.
+-   `context`: The context of the current query. Used to limit the scope of
+    searches. Can be matched directly using the `:scope` pseudo-selector.
+-   `cacheResults`: Allow css-select to cache results for some selectors,
+    sometimes greatly improving querying performance. Disable this if your
+    document can change in between queries with the same compiled selector.
+    Default: `true`.
+
+#### Custom Adapters
+
+A custom adapter must match the interface described
+[here](https://github.com/fb55/css-select/blob/1aa44bdd64aaf2ebdfd7f338e2e76bed36521957/src/types.ts#L6-L96).
+
+You may want to have a look at [`domutils`](https://github.com/fb55/domutils) to
+see the default implementation, or at
+[`css-select-browser-adapter`](https://github.com/nrkn/css-select-browser-adapter/blob/master/index.js)
+for an implementation backed by the DOM.

+
+- Dropped support for Node < 8
+- Updated dev deps (fixed `npm audit` issues)

+- Lexer
+    - Added [bracketed range notation](https://drafts.csswg.org/css-values-4/#numeric-ranges) support and related refactoring

+    - Added support for multiple token string matching
+    - Improved `<custom-ident>` production matching to claim the keyword only if no other unfulfilled production can claim it (#101)
+    - Improved `<length>` production matching to claim "unitless zero" only if no other unfulfilled production can claim it

+    - Fixed large `||`- and `&&`-group matching, matching continues from the beginning on term match (#85)
+    - Fixed checking that value has `var()` occurrences when value is a string (such values can't be matched on syntax currently and fail with specific error that can be used for ignorance in validation tools)
+    - Fixed `<declaration-value>` and `<any-value>` matching when a value contains a function, parentheses or braces
+
+## 1.0.0-alpha.30 (July 3, 2019)
+
+- Bumped `mdn/data` to `~2.0.3`
+    - Removed type removals from `mdn/data` due to lack of some generic types and specific lexer restictions (since lexer was reworked, see below)
+    - Reduced and updated patches
+- Tokenizer
+    - Reworked tokenizer itself to compliment [CSS Syntax Module Level 3](https://drafts.csswg.org/css-syntax/#tokenization)
+    - `Tokenizer` class splitted into several abstractions:
+        - Added `TokenStream` class
+        - Added `OffsetToLocation` class
+        - Added `tokenize()` function that creates `TokenStream` instance for given string or updates a `TokenStream` instance passed as second parameter
+        - Removed `Tokenizer` class
+    - Removed `Raw` token type
+    - Renamed `Identifier` token type to `Ident`
+    - Added token types: `Hash`, `BadString`, `BadUrl`, `Delim`, `Percentage`, `Dimension`, `Colon`, `Semicolon`, `Comma`, `LeftSquareBracket`, `RightSquareBracket`, `LeftParenthesis`, `RightParenthesis`, `LeftCurlyBracket`, `RightCurlyBracket`
+    - Replaced `Punctuator` with `Delim` token type, that excludes specific characters with its own token type like `Colon`, `Semicolon` etc
+    - Removed `findCommentEnd`, `findStringEnd`, `findDecimalNumberEnd`, `findNumberEnd`, `findEscapeEnd`, `findIdentifierEnd` and `findUrlRawEnd` helper function
+    - Removed `SYMBOL_TYPE`, `PUNCTUATION` and `STOP_URL_RAW` dictionaries
+    - Added `isDigit`, `isHexDigit`, `isUppercaseLetter`, `isLowercaseLetter`, `isLetter`, `isNonAscii`, `isNameStart`, `isName`, `isNonPrintable`, `isNewline`, `isWhiteSpace`, `isValidEscape`, `isIdentifierStart`, `isNumberStart`, `consumeEscaped`, `consumeName`, `consumeNumber` and `consumeBadUrlRemnants` helper functions
+- Parser
+    - Changed parsing algorithms to work with new token type set
+    - Changed `HexColor` consumption in way to relax checking a value, i.e. now `value` is a sequence of one or more name chars
+    - Added `&` as a property hack
+    - Relaxed `var()` parsing to only check that a first arguments is an identifier (not a custom property name as before)
+- Lexer
+    - Reworked syntax matching to relay on token set only (having AST is optional now)
+    - Extended `Lexer#match()`, `Lexer#matchType()` and `Lexer#matchProperty()` methods to take a string as value, beside AST as a value
+    - Extended `Lexer#match()` method to take a string as a syntax, beside of syntax descriptor
+    - Reworked generic types:
+        - Removed `<attr()>`, `<url>` (moved to patch) and `<progid>` types
+        - Added types:
+            - Related to token types: `<ident-token>`, `<function-token>`, `<at-keyword-token>`, `<hash-token>`, `<string-token>`, `<bad-string-token>`, `<url-token>`, `<bad-url-token>`, `<delim-token>`, `<number-token>`, `<percentage-token>`, `<dimension-token>`, `<whitespace-token>`, `<CDO-token>`, `<CDC-token>`, `<colon-token>`, `<semicolon-token>`, `<comma-token>`, `<[-token>`, `<]-token>`, `<(-token>`, `<)-token>`, `<{-token>` and `<}-token>`
+            - Complex types: `<an-plus-b>`, `<urange>`, `<custom-property-name>`, `<declaration-value>`, `<any-value>` and `<zero>`
+        - Renamed `<unicode-range>` to `<urange>` as per spec
+        - Renamed `<expression>` (IE legacy extension) to `<-ms-legacy-expression>` and may to be removed in next releases
+
+## 1.0.0-alpha.29 (May 30, 2018)
+
+- Lexer
+    - Syntax matching was completely reworked. Now it's token-based and uses state machine. Public API has not changed. However, some internal data structures have changed. Most significal change in syntax match result tree structure, it's became token-based instead of node-based.
+    - Grammar
+        - Changed grammar tree format:
+            - Added `Token` node type to represent a single code point (`<delim-token>`)
+            - Added `Multiplier` that wraps a single node (`term` property)
+            - Added `AtKeyword` to represent `<at-keyword-token>`
+            - Removed `Slash` and `Percent` node types, they are replaced for a node with `Token` type
+            - Changed `Function` to represent `<function-token>` with no children
+            - Removed `multiplier` property from `Group`
+        - Changed `generate()` method:
+            - Method takes an `options` as second argument now (`generate(node, forceBraces, decorator)` -> `generate(node, options)`). Two options are supported: `forceBraces` and `decorator`
+            - When a second parameter is a function it treats as `decorate` option value, i.e. `generate(node, fn)` -> `generate(node, { decorate: fn })`
+            - Decorate function invokes with additional parameter – a reference to a node
+- Tokenizer
+    - Renamed `Atrule` const to `AtKeyword`
+
+## 1.0.0-alpha.28 (February 19, 2018)
+
+- Renamed `lexer.grammar.translate()` method into `generate()`
+- Fixed `<'-webkit-font-smoothing'>` and `<'-moz-osx-font-smoothing'>` syntaxes (#75)
+- Added vendor keywords for `<'overflow'>` property syntax (#76)
+- Pinned `mdn-data` to `~1.1.0` and fixed issues with some updated property syntaxes
+
+## 1.0.0-alpha.27 (January 14, 2018)
+
+- Generator
+    - Changed node's `generate()` methods invocation, methods now take a node as a single argument and context (i.e. `this`) that have methods: `chunk()`, `node()` and `children()`
+    - Renamed `translate()` to `generate()` and changed to take `options` argument
+    - Removed `translateMarkup(ast, enter, leave)` method, use `generate(ast, { decorator: (handlers) => { ... }})` instead
+    - Removed `translateWithSourceMap(ast)`, use `generate(ast, { sourceMap: true })` instead
+    - Changed to support for children as an array
+- Walker
+    - Changed `walk()` to take an `options` argument instead of handler, with `enter`, `leave`, `visit` and `reverse` options (`walk(ast, fn)` is still works and equivalent to `walk(ast, { enter: fn })`)
+    - Removed `walkUp(ast, fn)`, use `walk(ast, { leave: fn })`
+    - Removed `walkRules(ast, fn)`, use `walk(ast, { visit: 'Rule', enter: fn })` instead
+    - Removed `walkRulesRight(ast, fn)`, use `walk(ast, { visit: 'Rule', reverse: true, enter: fn })` instead
+    - Removed `walkDeclarations(ast, fn)`, use `walk(ast, { visit: 'Declaration', enter: fn })` instead
+    - Changed to support for children as array in most cases (`reverse: true` will fail on arrays since they have no `forEachRight()` method)
+- Misc
+    - List
+        - Added `List#forEach()` method
+        - Added `List#forEachRight()` method
+        - Added `List#filter()` method
+        - Changed `List#map()` method to return a `List` instance instead of `Array`
+        - Added `List#push()` method, similar to `List#appendData()` but returns nothing
+        - Added `List#pop()` method
+        - Added `List#unshift()` method, similar to `List#prependData()` but returns nothing
+        - Added `List#shift()` method
+        - Added `List#prependList()` method
+        - Changed `List#insert()`, `List#insertData()`, `List#appendList()` and `List#insertList()` methods to return a list that performed an operation
+    - Changed `keyword()` method
+        - Changed `name` field to include a vendor prefix
+        - Added `basename` field to contain a name without a vendor prefix
+        - Added `custom` field that contain a `true` when keyword is a custom property reference
+    - Changed `property()` method
+        - Changed `name` field to include a vendor prefix
+        - Added `basename` field to contain a name without any prefixes, i.e. a hack and a vendor prefix
+    - Added `vendorPrefix()` method
+    - Added `isCustomProperty()` method
+
+## 1.0.0-alpha.26 (November 9, 2017)
+
+- Tokenizer
+    - Added `Tokenizer#isBalanceEdge()` method
+    - Removed `Tokenizer.endsWith()` method
+- Parser
+    - Made the parser tolerant to errors by default
+    - Removed `tolerant` parser option (no parsing modes anymore)
+    - Removed `property` parser option (a value parsing does not depend on property name anymore)
+    - Canceled error for a handing semicolon in a block
+    - Canceled error for unclosed `Brackets`, `Function` and `Parentheses` when EOF is reached
+    - Fixed error when prelude ends with a comment for at-rules with custom prelude consumer
+    - Relaxed at-rule parsing:
+        - Canceled error when EOF is reached after a prelude
+        - Canceled error for an at-rule with custom block consumer when at-rule has no block (just don't apply consumer in that case)
+        - Canceled error on at-rule parsing when it occurs outside prelude or block (at-rule is converting to `Raw` node)
+        - Allowed for any at-rule to have a prelude and a block, even if it's invalid per at-rule syntax (the responsibility for this check is moved to lexer, since it's possible to construct a AST with such errors)
+    - Made a declaration value a safe parsing point (i.e. error on value parsing lead to a value is turning into `Raw` node, not a declaration as before)
+    - Excluded surrounding white spaces and comments from a `Raw` node that represents a declaration value
+    - Changed `Value` parse handler to return a node only with type `Value` (previously it returned a `Raw` node in some cases)
+    - Fixed issue with `onParseError()` is not invoked for errors occured on selector or declaration value parsing in some cases
+    - Changed using of `onParseError()` to stop parsing if handler throws an exception
+- Lexer
+    - Changed `grammar.walk()` to invoke passed handler on entering to node rather than on leaving the node
+    - Improved `grammar.walk()` to take a walk handler pair as an object, i.e. `walk(node, { enter: fn, leave: fn })`
+    - Changed `Lexer#match*()` methods to take a node of any type, but with a `children` field
+    - Added `Lexer#match(syntax, node)` method
+    - Fixed `Lexer#matchType()` method to stop return a positive result for the CSS wide keywords
+
+## 1.0.0-alpha25 (October 9, 2017)
+
+- Parser
+    - Added fallback node as argument to `onParseError()` handler
+    - Fixed raw consuming in tolerant mode when selector is invalid (greedy consuming and redundant warnings)
+    - Fixed exception in tolerant mode caused by unknown at-rule with unclosed block
+    - Changed handling of semicolons:
+        - Hanging semicolon inside declaration blocks raise an error or turns into a `Raw` node in tolerant mode instead of being ignored
+        - Semicolon outside of declaration blocks opens a `Rule` node as part of selector instead of being ignored
+    - Aligned `parseAtrulePrelude` behaviour to `parseRulePrelude`
+        - Removed `Raw` node wraping into `AtrulePrelude` when `parseAtrulePrelude` is disabled
+        - Removed error emitting when at-rule has a custom prelude customer but no prelude is found (it should be validated by a lexer later)
+- Generator
+    - Fixed performance issue with `translateWithSourceMap()`, flattening the string (because of mixing building string and indexing into it) turned it into a quadratic algorithm (approximate numbers can be found in [the quiz created by this case](https://gist.github.com/lahmatiy/ea25d0e623d88ca9848384b5707d52d9))
+- Added support for a single solidus hack for `property()`
+- Minor fixes for custom errors
+
+## 1.0.0-alpha24 (September 14, 2017)
+
+- Improved CSSTree to be stable for standart build-in objects extension (#58)
+- Parser
+    - Renamed rule's `selector` to `prelude`. The reasons: [spec names this part so](https://www.w3.org/TR/css-syntax-3/#qualified-rule), and this branch can contain not only a selector (`SelectorList`) but also a raw payload (`Raw`). What's changed:
+        - Renamed `Rule.selector` to `Rule.prelude`
+        - Renamed `parseSelector` parser option to `parseRulePrelude`
+        - Removed option for selector parse in `SelectorList`
+- Lexer
+    - Fixed undefined positions in a error when match a syntax to empty or white space only value
+    - Improved `Lexer#checkStructure()`
+        - Return a warning as an object with node reference and message
+        - No exception on unknown node type, return a warning instead
+
+## 1.0.0-alpha23 (September 10, 2017)
+
+- Fixed `Tokenizer#getRawLength()`'s false positive balance match to the end of input in some cases (#56)
+- Rename walker's entry point methods to be the same as CSSTree exposed methods (i.e. `walk()`, `walkUp()` etc)
+- Rename at-rule's `expression` to `prelude` (since [spec names it so](https://www.w3.org/TR/css-syntax-3/#at-rule))
+    - `AtruleExpression` node type → `AtrulePrelude`
+    - `Atrule.expression` field → `Atrule.prelude`
+    - `parseAtruleExpression` parser's option → `parseAtrulePrelude`
+    - `atruleExpression` parse context → `atrulePrelude`
+    - `atruleExpression` walk context reference → `atrulePrelude`
+
+## 1.0.0-alpha22 (September 8, 2017)
+
+- Parser
+    - Fixed exception on parsing of unclosed `{}-block` in tolerant mode
+    - Added tolerant mode support for `DeclarationList`
+    - Added standalone entry point, i.e. default parser can be used via `require('css-tree/lib/parser')` (#47)
+- Generator
+    - Changed generator to produce `+n` when `AnPlusB.a` is `+1` to be "round-trip" with parser
+    - Added standalone entry point, i.e. default generators can be used via `require('css-tree/lib/generator')`
+- Walker
+    - Added standalone entry point, i.e. default walkers can be used via `require('css-tree/lib/walker')` (#47)
+- Lexer
+    - Added `default` keyword to the list of invalid values for `<custom-ident>` (since it reversed per [spec](https://www.w3.org/TR/css-values/#custom-idents))
+- Convertors (`toPlainObject()` and `fromPlainObject()`) moved to `lib/convertor` (entry point is `require('css-tree/lib/convertor')`)
+
+## 1.0.0-alpha21 (September 5, 2017)
+
+- Tokenizer
+    - Added `Raw` token type
+    - Improved tokenization of `url()` with raw as url to be more spec complient
+    - Added `Tokenizer#balance` array computation on token layout
+    - Added `Tokenizer#getRawLength()` to compute a raw length with respect of block balance
+    - Added `Tokenizer#getTokenStart(offset)` method to get token start offset by token index
+    - Added `idx` and `balance` fields to each token of `Tokenizer#dump()` method result
+- Parser
+    - Added `onParseError` option
+    - Reworked node parsers that consume a `Raw` node to use a new approach. Since now a `Raw` node builds in `parser#Raw()` function only
+    - Changed semantic of `parser#Raw()`, it takes 5 parameters now (it might to be changed in future)
+    - Changed `parser#tolerantParse()` to pass a start token index to fallback function instead of source offset
+    - Fixed `AtruleExpression` consuming in tolerant mode
+    - Atrule handler to convert an empty `AtruleExpression` node into `null`
+    - Changed `AtruleExpression` handler to always return a node (before it could return a `null` in some cases)
+- Lexer
+    - Fixed comma match node for `#` multiplier
+    - Added reference name to `SyntaxReferenceError`
+- Additional fixes on custom errors
+- Reduced possible corruption of base config by `syntax.fork()`
+
+## 1.0.0-alpha20 (August 28, 2017)
+
+- Tokenizer
+    - Added `Atrule` token type (`<at-rule-token>` per spec)
+    - Added `Function` token type (`<function-token>` per spec)
+    - Added `Url` token type
+    - Replaced `Tokenizer#getTypes()` method with `Tokenizer#dump()` to get all tokens as an array
+    - Renamed `Tokenizer.TYPE.Whitespace` to `Tokenizer.TYPE.WhiteSpace`
+    - Renamed `Tokenizer.findWhitespaceEnd()` to `Tokenizer.findWhiteSpaceEnd()`
+- Parser
+    - Added initial implementation of tollerant mode (turn on by passing `tolerant: true` option). In this mode parse errors are never occour and any invalid part of CSS turns into a `Raw` node. Current safe points: `Atrule`, `AtruleExpression`, `Rule`, `Selector` and `Declaration`. Feature is experimental and further improvements are planned.
+    - Changed `Atrule.expression` to contain a `AtruleExpression` node or `null` only (other node types is wrapping into a `AtruleExpression` node)
+    - Renamed `AttributeSelector.operator` to `AttributeSelector.matcher`
+- Generator
+    - `translate()` method is now can take a function as second argument, that recieves every generated chunk. When no function is passed, default handler is used, it concats all the chunks and method returns a string.
+- Lexer
+    - Used [mdn/data](https://github.com/mdn/data) package as source of lexer's grammar instead of local dictionaries
+    - Added `x` unit to `<resolution>` generic type
+    - Improved match tree:
+        - Omited Group (sequences) match nodes
+        - Omited empty match nodes (for terms with `zero or more` multipliers)
+        - Added `ASTNode` node type to contain a reference to AST node
+        - Fixed node duplication (uncompleted match were added to tree)
+        - Added AST node reference in match nodes
+        - Added comma match node by `#` multiplier
+    - Grammar
+        - Changed `translate()` function to get a handler as third argument (optional). That handler recieves result of node traslation and can be used for decoration purposes. See [example](https://github.com/csstree/docs/blob/04c65af44477b5ea05feb373482898122b2a4528/docs/syntax.html#L619-L627)
+        - Added `SyntaxParseError` to grammar export
+        - Reworked group and multipliers representation in syntax tree:
+            - Replaced `Sequence` for `Group` node type (`Sequence` node type removed)
+            - Added `explicit` boolean property for `Group`
+            - Only groups can have a multiplier now (other node types is wrapping into a single term implicit group when multiplier is applied)
+            - Renamed `nonEmpty` Group's property to `disallowEmpty`
+            - Added optimisation for syntax tree by dropping redundant root `Group` when it contains a single `Group` term (return this `Group` as a result)
+    - Changed lexer's match functionality
+        - Changed `Lexer#matchProperty()` and `Lexer#matchType()` to return an object instead of match tree. A match tree stores in `matched` field when AST is matched to grammar successfully, otherwise an error in `error` field. The result object also has some methods to test AST node against a match tree: `getTrace()`, `isType()`, `isProperty()` and `isKeyword()`
+        - Added `Lexer#matchDeclaration()` method
+        - Removed `Lexer#lastMatchError` (error stores in match result object in `error` field)
+    - Added initial implementation of search for AST segments (new lexer methods: `Lexer#findValueSegments()`, `Lexer#findDeclarationValueSegments()` and `Lexer#findAllSegments`)
+    - Implemented `SyntaxReferenceError` for unknown property and type references
+- Renamed field in resulting object of `property()` function: `variable` → `custom`
+- Fixed issue with readonly properties (e.g. `line` and `column`) of `Error` and exception on attempt to write in iOS Safari
+
+## 1.0.0-alpha19 (April 24, 2017)
+
+- Extended `List` class with new methods:
+    - `List#prepend(item)`
+    - `List#prependData(data)`
+    - `List#insertData(data)`
+    - `List#insertList(list)`
+    - `List#replace(item, itemOrList)`
+

+
+- Added `atrule` walk context (#39)
+- Changed a result of generate method for `AnPlusB`, `AttributeSelector`, `Function`, `MediaFeature` and `Ratio` ([1e95877](https://github.com/csstree/csstree/commit/1e9587710efa8e9338bcf0bc794b4b45f286231d))

+- Exposed `Parser` class
+- Added `startOffset` option to `Tokenizer` (constructor and `setSource()` method)
+- Added fallback functions for default (`readSequenceFallback`) and selector (`readSelectorSequenceFallback`) sequence readers
+- Fixed edge cases for `AnPlusB`
+- Fixed wrong whitespace ignoring in `Selector` consumer
+
+## 1.0.0-alpha15 (February 8, 2017)

+CSSTree is a tool set for CSS: [fast](https://github.com/postcss/benchmark) detailed parser (CSS → AST), walker (AST traversal), generator (AST → CSS) and lexer (validation and matching) based on specs and browser implementations. The main goal is to be efficient and W3C specs compliant, with focus on CSS analyzing and source-to-source transforming tasks.
+
+> NOTE: The library isn't in final shape and needs further improvements (e.g. AST format and API are subjects to change in next major versions). However it's stable enough and used by projects like [CSSO](https://github.com/css/csso) (CSS minifier) and [SVGO](https://github.com/svg/svgo) (SVG optimizer) in production.
+
+## Features
+
+- **Detailed parsing with an adjustable level of detail**
+
+  By default CSSTree parses CSS as detailed as possible, i.e. each single logical part is representing with its own AST node (see [AST format](docs/ast.md) for all possible node types). The parsing detail level can be changed through [parser options](docs/parsing.md#parsesource-options), for example, you can disable parsing of selectors or declaration values for component parts.
+
+- **Tolerant to errors by design**
+
+  Parser behaves as [spec says](https://www.w3.org/TR/css-syntax-3/#error-handling): "When errors occur in CSS, the parser attempts to recover gracefully, throwing away only the minimum amount of content before returning to parsing as normal". The only thing the parser departs from the specification is that it doesn't throw away bad content, but wraps it in a special node type (`Raw`) that allows processing it later.
+
+- **Fast and efficient**
+
+  CSSTree is created with focus on performance and effective memory consumption. Therefore it's [one of the fastest CSS parsers](https://github.com/postcss/benchmark) at the moment.
+
+- **Syntax validation**
+
+  The build-in lexer can test CSS against syntaxes defined by W3C. CSSTree uses [mdn/data](https://github.com/mdn/data/) as a basis for lexer's dictionaries and extends it with vendor specific and legacy syntaxes. Lexer can only check the declaration values currently, but this feature will be extended to other parts of the CSS in the future.

+
+## Usage
+
+Install with npm:
+
+```
+> npm install css-tree
+```
+
+Basic usage:
+
+```js
+var csstree = require('css-tree');
+
+// parse CSS to AST
+var ast = csstree.parse('.example { world: "!" }');
+
+// traverse AST and modify it
+csstree.walk(ast, function(node) {
+    if (node.type === 'ClassSelector' && node.name === 'example') {
+        node.name = 'hello';
+    }
+});
+
+// generate CSS from AST
+console.log(csstree.generate(ast));
+// .hello{world:"!"}
+```
+
+Syntax matching:
+
+```js
+// parse CSS to AST as a declaration value
+var ast = csstree.parse('red 1px solid', { context: 'value' });
+
+// match to syntax of `border` property
+var matchResult = csstree.lexer.matchProperty('border', ast);
+
+// check first value node is a <color>
+console.log(matchResult.isType(ast.children.first(), 'color'));
+// true
+
+// get a type list matched to a node
+console.log(matchResult.getTrace(ast.children.first()));
+// [ { type: 'Property', name: 'border' },
+//   { type: 'Type', name: 'color' },
+//   { type: 'Type', name: 'named-color' },
+//   { type: 'Keyword', name: 'red' } ]
+```
