# 5.0.0
- Allow escaped dot within class name.
- Update PostCSS to 7.0.7 (patch)
# 5.0.0-rc.4
- Fixed and issue where comments immediately after an insensitive
(in attribute) were not parsed correctly.
- Updated `cssesc` to 2.0.0 (major).
- Removed outdated integration tests.
- Added tests for custom selectors, tags with attributes, the universal
selector with pseudos, and tokens after combinators.
# 5.0.0-rc.1
To ease adoption of the v5.0 release, we have relaxed the node version
check performed by npm at installation time to allow for node 4, which
remains officially unsupported, but likely to continue working for the
time being.
# 5.0.0-rc.0
This release has **BREAKING CHANGES** that were required to fix regressions
in 4.0.0 and to make the Combinator Node API consistent for all combinator
types. Please read carefully.
## Summary of Changes
* The way a descendent combinator that isn't a single space character (E.g. `.a .b`) is stored in the AST has changed.
* Named Combinators (E.g. `.a /for/ .b`) are now properly parsed as a combinator.
* It is now possible to look up a node based on the source location of a character in that node and to query nodes if they contain some character.
* Several bug fixes that caused the parser to hang and run out of memory when a `/` was encountered have been fixed.
* The minimum supported version of Node is now `v6.0.0`.
### Changes to the Descendent Combinator
In prior releases, the value of a descendant combinator with multiple spaces included all the spaces.
* `.a .b`: Extra spaces are now stored as space before.
- Old & Busted:
- `combinator.value === " "`
- New hotness:
- `combinator.value === " " && combinator.spaces.before === " "`
* `.a /*comment*/.b`: A comment at the end of the combinator causes extra space to become after space.
- Old & Busted:
- `combinator.value === " "`
- `combinator.raws.value === " /*comment/"`
- New hotness:
- `combinator.value === " "`
- `combinator.spaces.after === " "`
- `combinator.raws.spaces.after === " /*comment*/"`
* `.a<newline>.b`: whitespace that doesn't start or end with a single space character is stored as a raw value.
- Old & Busted:
- `combinator.value === "\n"`
- `combinator.raws.value === undefined`
- New hotness:
- `combinator.value === " "`
- `combinator.raws.value === "\n"`
### Support for "Named Combinators"
Although, nonstandard and unlikely to ever become a standard, combinators like `/deep/` and `/for/` are now properly supported.
Because they've been taken off the standardization track, there is no spec-official name for combinators of the form `/<ident>/`. However, I talked to [Tab Atkins](https://twitter.com/tabatkins) and we agreed to call them "named combinators" so now they are called that.
Before this release such named combinators were parsed without intention and generated three nodes of type `"tag"` where the first and last nodes had a value of `"/"`.
* `.a /for/ .b` is parsed as a combinator.
- Old & Busted:
- `root.nodes[0].nodes[1].type === "tag"`
- `root.nodes[0].nodes[1].value === "/"`
- New hotness:
- `root.nodes[0].nodes[1].type === "combinator"`
- `root.nodes[0].nodes[1].value === "/for/"`
* `.a /F\6fR/ .b` escapes are handled and uppercase is normalized.
- Old & Busted:
- `root.nodes[0].nodes[2].type === "tag"`
- `root.nodes[0].nodes[2].value === "F\\6fR"`
- New hotness:
- `root.nodes[0].nodes[1].type === "combinator"`
- `root.nodes[0].nodes[1].value === "/for/"`
- `root.nodes[0].nodes[1].raws.value === "/F\\6fR/"`
### Source position checks and lookups
A new API was added to look up a node based on the source location.
```js
const selectorParser = require("postcss-selector-parser");
// You can find the most specific node for any given character
let combinator = selectorParser.astSync(".a > .b").atPosition(1,4);
combinator.toString() === " > ";
// You can check if a node includes a specific character
// Whitespace surrounding the node that is owned by that node
// is included in the check.
[2,3,4,5,6].map(column => combinator.isAtPosition(1, column));
// => [false, true, true, true, false]
```
# 4.0.0
This release has **BREAKING CHANGES** that were required to fix bugs regarding values with escape sequences. Please read carefully.
* **Identifiers with escapes** - CSS escape sequences are now hidden from the public API by default.
The normal value of a node like a class name or ID, or an aspect of a node such as attribute
selector's value, is unescaped. Escapes representing Non-ascii characters are unescaped into
unicode characters. For example: `bu\tton, .\31 00, #i\2764\FE0Fu, [attr="value is \"quoted\""]`
will parse respectively to the values `button`, `100`, `i❤️u`, `value is "quoted"`.
The original escape sequences for these values can be found in the corresponding property name
in `node.raws`. Where possible, deprecation warnings were added, but the nature
of escape handling makes it impossible to detect what is escaped or not. Our expectation is
that most users are neither expecting nor handling escape sequences in their use of this library,
and so for them, this is a bug fix. Users who are taking care to handle escapes correctly can
now update their code to remove the escape handling and let us do it for them.
* **Mutating values with escapes** - When you make an update to a node property that has escape handling
The value is assumed to be unescaped, and any special characters are escaped automatically and
the corresponding `raws` value is immediately updated. This can result in changes to the original
escape format. Where the exact value of the escape sequence is important there are methods that
allow both values to be set in conjunction. There are a number of new convenience methods for
manipulating values that involve escapes, especially for attributes values where the quote mark
is involved. See https://github.com/postcss/postcss-selector-parser/pull/133 for an extensive
write-up on these changes.
**Upgrade/API Example**
In `3.x` there was no unescape handling and internal consistency of several properties was the caller's job to maintain. It was very easy for the developer
to create a CSS file that did not parse correctly when some types of values
were in use.
```js
const selectorParser = require("postcss-selector-parser");
let attr = selectorParser.attribute({attribute: "id", operator: "=", value: "a-value"});
attr.value; // => "a-value"
attr.toString(); // => [id=a-value]
// Add quotes to an attribute's value.
// All these values have to be set by the caller to be consistent:
// no internal consistency is maintained.
attr.raws.unquoted = attr.value
attr.value = "'" + attr.value + "'";
attr.value; // => "'a-value'"
attr.quoted = true;
attr.toString(); // => "[id='a-value']"
```
In `4.0` there is a convenient API for setting and mutating values
that may need escaping. Especially for attributes.
```js
const selectorParser = require("postcss-selector-parser");

```
# 3.1.2
* Fix: Removed dot-prop dependency since it's no longer written in es5.
# 3.1.1
* Fix: typescript definitions weren't in the published package.
# 3.1.0
* Fixed numerous bugs in attribute nodes relating to the handling of comments
and whitespace. There's significant changes to `attrNode.spaces` and `attrNode.raws` since the `3.0.0` release.
* Added `Attribute#offsetOf(part)` to get the offset location of
attribute parts like `"operator"` and `"value"`. This is most
often added to `Attribute#sourceIndex` for error reporting.
# 3.0.0
## Breaking changes
* Some tweaks to the tokenizer/attribute selector parsing mean that whitespace
locations might be slightly different to the 2.x code.
* Better attribute selector parsing with more validation; postcss-selector-parser
no longer uses regular expressions to parse attribute selectors.
* Added an async API (thanks to @jacobp100); the default `process` API is now
async, and the sync API is now accessed through `processSync` instead.
* `process()` and `processSync()` now return a string instead of the Processor
instance.
* Tweaks handling of Less interpolation (thanks to @jwilsson).
* Removes support for Node 0.12.
## Other changes
* `ast()` and `astSync()` methods have been added to the `Processor`. These
return the `Root` node of the selectors after processing them.
* `transform()` and `transformSync()` methods have been added to the
`Processor`. These return the value returned by the processor callback
after processing the selectors.
* Set the parent when inserting a node (thanks to @chriseppstein).
* Correctly adjust indices when using insertBefore/insertAfter (thanks to @tivac).
* Fixes handling of namespaces with qualified tag selectors.
* `process`, `ast` and `transform` (and their sync variants) now accept a
`postcss` rule node. When provided, better errors are generated and selector
processing is automatically set back to the rule selector (unless the `updateSelector` option is set to `false`.)
* Now more memory efficient when tokenizing selectors.
### Upgrade hints
The pattern of:
`rule.selector = processor.process(rule.selector).result.toString();`
is now:
`processor.processSync(rule)`
# 2.2.3
* Resolves an issue where the parser would not reduce multiple spaces between an
ampersand and another simple selector in lossy mode (thanks to @adam-26).
# 2.2.2
* No longer hangs on an unescaped semicolon; instead the parser will throw
an exception for these cases.
# 2.2.1
* Allows a consumer to specify whitespace tokens when creating a new Node
(thanks to @Semigradsky).
# 2.2.0
* Added a new option to normalize whitespace when parsing the selector string
(thanks to @adam-26).
# 2.1.1
* Better unquoted value handling within attribute selectors
(thanks to @evilebottnawi).
# 2.1.0
* Added: Use string constants for all node types & expose them on the main
parser instance (thanks to @Aweary).
# 2.0.0
This release contains the following breaking changes:
* Renamed all `eachInside` iterators to `walk`. For example, `eachTag` is now
`walkTags`, and `eachInside` is now `walk`.
* Renamed `Node#removeSelf()` to `Node#remove()`.
* Renamed `Container#remove()` to `Container#removeChild()`.
* Renamed `Node#raw` to `Node#raws` (thanks to @davidtheclark).
* Now parses `&` as the *nesting* selector, rather than a *tag* selector.
* Fixes misinterpretation of Sass interpolation (e.g. `#{foo}`) as an
id selector (thanks to @davidtheclark).
and;
* Fixes parsing of attribute selectors with equals signs in them
(e.g. `[data-attr="foo=bar"]`) (thanks to @montmanu).
* Adds `quoted` and `raw.unquoted` properties to attribute nodes
(thanks to @davidtheclark).
# 1.3.3
* Fixes an infinite loop on `)` and `]` tokens when they had no opening pairs.
Now postcss-selector-parser will throw when it encounters these lone tokens.
# 1.3.2
* Now uses plain integers rather than `str.charCodeAt(0)` for compiled builds.
# 1.3.1
* Update flatten to v1.x (thanks to @shinnn).
# 1.3.0
* Adds a new node type, `String`, to fix a crash on selectors such as
`foo:bar("test")`.
# 1.2.1
* Fixes a crash when the parser encountered a trailing combinator.
# 1.2.0
* A more descriptive error is thrown when the parser expects to find a
pseudo-class/pseudo-element (thanks to @ashelley).
* Adds support for line/column locations for selector nodes, as well as a
`Node#sourceIndex` method (thanks to @davidtheclark).
# 1.1.4
* Fixes a crash when a selector started with a `>` combinator. The module will
now no longer throw if a selector has a leading/trailing combinator node.
# 1.1.3
* Fixes a crash on `@` tokens.
# 1.1.2
* Fixes an infinite loop caused by using parentheses in a non-pseudo element
context.
# 1.1.1
* Fixes a crash when a backslash ended a selector string.
# 1.1.0
* Adds support for replacing multiple nodes at once with `replaceWith`
(thanks to @jonathantneal).
* Parser no longer throws on sequential IDs and trailing commas, to support
parsing of selector hacks.
# 1.0.1
* Fixes using `insertAfter` and `insertBefore` during iteration.
# 1.0.0
* Adds `clone` and `replaceWith` methods to nodes.
* Adds `insertBefore` and `insertAfter` to containers.
* Stabilises API.
# 0.0.5
* Fixes crash on extra whitespace inside a pseudo selector's parentheses.
* Adds sort function to the container class.
* Enables the parser to pass its input through without transforming.
* Iteration-safe `each` and `eachInside`.
# 0.0.4
* Tidy up redundant duplication.
* Fixes a bug where the parser would loop infinitely on universal selectors
inside pseudo selectors.
* Adds `length` getter and `eachInside`, `map`, `reduce` to the container class.
* When a selector has been removed from the tree, the root node will no longer
cast it to a string.
* Adds node type iterators to the container class (e.g. `eachComment`).
* Adds filter function to the container class.
* Adds split function to the container class.
* Create new node types by doing `parser.id(opts)` etc.
* Adds support for pseudo classes anywhere in the selector.
# 0.0.3
* Adds `next` and `prev` to the node class.
* Adds `first` and `last` getters to the container class.
* Adds `every` and `some` iterators to the container class.
* Add `empty` alias for `removeAll`.
* Combinators are now types of node.
* Fixes the at method so that it is not an alias for `index`.
* Tidy up creation of new nodes in the parser.
* Refactors how namespaces are handled for consistency & less redundant code.
* Refactors AST to use `nodes` exclusively, and eliminates excessive nesting.
* Fixes nested pseudo parsing.
* Fixes whitespace parsing.
# 0.0.2
* Adds support for namespace selectors.
* Adds support for selectors joined by escaped spaces - such as `.\31\ 0`.
# 0.0.1
* Initial release.

# postcss-selector-parser [![Build Status](https://travis-ci.org/postcss/postcss-selector-parser.svg?branch=master)](https://travis-ci.org/postcss/postcss-selector-parser)
> Selector parser with built in methods for working with selector strings.
## Install
With [npm](https://npmjs.com/package/postcss-selector-parser) do:
```
npm install postcss-selector-parser
```
## Quick Start
```js
const parser = require('postcss-selector-parser');
const transform = selectors => {
selectors.walk(selector => {
// do something with the selector
console.log(String(selector))
});
};
const transformed = parser(transform).processSync('h1, h2, h3');
```
To normalize selector whitespace:
```js
const parser = require('postcss-selector-parser');
const normalized = parser().processSync('h1, h2, h3', {lossless: false});
// -> h1,h2,h3
```
Async support is provided through `parser.process` and will resolve a Promise
with the resulting selector string.
## API
Please see [API.md](API.md).
## Credits
* Huge thanks to Andrey Sitnik (@ai) for work on PostCSS which helped
accelerate this module's development.
