[![Build Status](https://github.com/mck89/peast/actions/workflows/test.yml/badge.svg)](https://github.com/mck89/peast/actions/workflows/test.yml)
**Peast** _(PHP ECMAScript Abstract Syntax Tree)_ is a PHP 5.4+ library that parses JavaScript code, according to [ECMAScript specification](http://www.ecma-international.org/publications/standards/Ecma-262.htm), and generates an abstract syntax tree following the [ESTree standard](https://github.com/estree/estree).
Installation
-------------
Include the following requirement to your composer.json:
```json
{
"require": {
"mck89/peast": "dev-master"
}
}
```
Run `composer install` to install the package.
Then in your script include the autoloader and you can start using Peast:
```php
require_once "vendor/autoload.php";
$source = "var a = 1"; // Your JavaScript code
$ast = Peast\Peast::latest($source, $options)->parse(); // Parse it!
```
Known issues
-------------
When Xdebug is enabled and Peast is used to scan code that contains deeply nested functions, this fatal error can appear:
```
PHP Fatal error: Maximum function nesting level of '512' reached, aborting!
```
or
```
PHP Warning: Uncaught Error: Xdebug has detected a possible infinite loop, and aborted your script with a stack depth of '256' frames
```
To prevent this you can set `xdebug.max_nesting_level` to a higher value, such as 512.

AST generation and tokenization
==========
AST generation
-------------
To generate AST (abstract syntax tree) for your JavaScript code just write:
```php
$source = "var a = 1"; //JavaScript code
$ast = Peast\Peast::latest($source, $options)->parse();
```
The previous code generates this structure:
```
Peast\Syntax\Node\Program
getSourceType() => "script"
getBody() => array(
Peast\Syntax\Node\VariableDeclaration
getKind() => "var"
getDeclarations() => array(
Peast\Syntax\Node\VariableDeclarator
getId() => Peast\Syntax\Node\Identifier
getName() => "a"
getInit() => Peast\Syntax\Node\NumericLiteral
getFormat() => "decimal"
getValue() => 1
)
)
```
Tokenization
-------------
To tokenize your JavaScript code just write:
```php
$source = "var a = 1"; //JavaScript code
$tokens = Peast\Peast::latest($source, $options)->tokenize();
```
This function produces an array of tokens from your code:
```
array(
Peast\Syntax\Token
getType() => "Keyword"
getValue() => "var"
Peast\Syntax\Token
getType() => "Identifier"
getValue() => "a"
Peast\Syntax\Token
getType() => "Punctuator"
getValue() => "="
Peast\Syntax\Token
getType() => "Numeric"
getValue() => "1"
)
```
EcmaScript version
-------------
Peast can parse different versions of EcmaScript, you can choose the version by using the relative method on the main class.
Available methods are:
* ```Peast::ES2015(source, options)``` or ```Peast::ES6(source, options)```: parse using EcmaScript 2015 (ES6) syntax
* ```Peast::ES2016(source, options)``` or ```Peast::ES7(source, options)```: parse using EcmaScript 2016 (ES7) syntax
* ```Peast::ES2017(source, options)``` or ```Peast::ES8(source, options)```: parse using EcmaScript 2017 (ES8) syntax
* ```Peast::ES2018(source, options)``` or ```Peast::ES9(source, options)```: parse using EcmaScript 2018 (ES9) syntax
* ```Peast::ES2019(source, options)``` or ```Peast::ES10(source, options)```: parse using EcmaScript 2019 (ES10) syntax
* ```Peast::ES2020(source, options)``` or ```Peast::ES11(source, options)```: parse using EcmaScript 2020 (ES11) syntax
* ```Peast::ES2021(source, options)``` or ```Peast::ES12(source, options)```: parse using EcmaScript 2021 (ES12) syntax
* ```Peast::ES2022(source, options)``` or ```Peast::ES13(source, options)```: parse using EcmaScript 2022 (ES13) syntax
* ```Peast::ES2023(source, options)``` or ```Peast::ES14(source, options)```: parse using EcmaScript 2023 (ES14) syntax
* ```Peast::ES2024(source, options)``` or ```Peast::ES15(source, options)```: parse using EcmaScript 2024 (ES15) syntax
* ```Peast::ES2025(source, options)``` or ```Peast::ES16(source, options)```: parse using EcmaScript 2025 (ES16) syntax
* ```Peast::latest(source, options)```: parse using the latest EcmaScript syntax version implemented
Options
-------------
In the examples above you may have noticed the `$options` parameter. This parameter is an associative array that specifies parsing settings for the parser. Available options are:
* "sourceType": this can be one of the source type constants defined in the Peast class:
* `Peast\Peast::SOURCE_TYPE_SCRIPT`: this is the default source type and indicates that the code is a script, this means that `import` and `export` keywords are not parsed
* `Peast\Peast::SOURCE_TYPE_MODULE`: this indicates that the code is a module and it activates the parsing of `import` and `export` keywords
* "comments" (from version 1.5): enables comments parsing and attaches the comments to the nodes in the tree. You can get comments attached to nodes using `getLeadingComments` and `getTrailingComments` methods.
* "jsx" (from version 1.8): enables parsing of JSX syntax.
* "sourceEncoding": to specify the encoding of the code to parse, if not specified the parser will assume UTF-8.
* "strictEncoding": if false the parser will handle invalid UTF8 characters in the source code by replacing them with the character defined in the "mbstring.substitute_character" ini setting, otherwise it will throw an exception. (available from version 1.9.4)
Differences from ESTree
-------------
There is only one big difference from ESTree: parenthesized expressions. This type of expressions have been introduced to let the user know if when an expression is wrapped in round brackets. For example `(a + b)` is a parenthesized expression and generates a ParenthesizedExpression node.
From version 1.3, literals have their own classes: `StringLiteral`, `NumericLiteral`, `BooleanLiteral` and `NullLiteral`.
From version 1.8, when parsing JSX, 2 new token types are emitted: `JSXIdentifier`, that represents a valid JSX identifier, and `JSXText`, that represents text inside JSX elements and fragments.
From version 1.13.7, the new `rawName` property has been added to `Identifiers` nodes. This property reports the raw name of the identifier with unconverted unicode escape sequences.

Querying By Selector
==========
**_From version 1.12_**
Inspired by [esquery](https://github.com/estools/esquery) project, Peast allows you to query the generated AST using a syntax similar to CSS selectors.
This can be done using the **Query** class:
```php
//Generate the AST
$ast = Peast\Peast::latest($source, $options)->parse();
//Query the AST
$query = new Peast\Query($ast, $options);
$query->find("Literal[value='search me']");
```
Or you can use the shortcut method on the `Program` node (the one returned by Peast parser):
```php
//Generate the AST
$ast = Peast\Peast::latest($source, $options)->parse();
//Query the AST
$query = $ast->query("Literal[value='search me']");
```
The shortcut method returns a Query instance.
Options
-------------
The Query class constructor takes an optional associative array of options.
Available options are:
* "encoding": to specify the encoding of the selector, if not specified the parser will assume UTF-8.
Methods
-------------
### find
The `find` method searches node that match the given selector starting from the current matching nodes.
For example this code matches `FunctionDeclaration` nodes and then finds all the descendant `Literal` nodes:
```php
$ast->query("FunctionDeclaration")->find("Literal");
```
### filter
The `filter` method filters the current matching nodes and keeps only those that respect the given selector.
For example this code matches `Literal` nodes and then keeps only the nodes whose value is 2:
```php
$ast->query("FunctionDeclaration")->filter("[value=2]");
```
### count
The `count` method returns the number of current matching nodes.
You can also use the builtin `count` function:
```php
$ast->query("FunctionDeclaration")->count();
//Or
count($ast->query("FunctionDeclaration"));
```
### get
The `get` method returns the node at the given index:
```php
//Returns the first matching node
$ast->query("FunctionDeclaration")->get(0);
```
Iteration
-------------
You can use the Query object in a foreach to loop all the matching nodes:
```php
foreach ($ast->query("FunctionDeclaration") as $node) {
//...
}
```
Selectors syntax
-------------
Note that Peast tries to preserve the order of the nodes in the AST, but that is not always possible, so you shouldn't rely on that.
### Filter by type
You can filter nodes by their type simply writing it.
For example `Literal` matches all the nodes whose type is Literal.
### Filter by attribute
You can filter nodes by their attributes writing the name and optionally the value inside square brackets.
There are several types of attribute filters:
* `[value]` matches all the nodes that have a `value` attribute, without checking its value
* `[value="test"]` matches all the nodes whose `value` attribute equals to the string "test"
* `[value^="test"]` matches all the nodes whose `value` attribute starts with the string "test"
* `[value*="test"]` matches all the nodes whose `value` attribute contains the string "test"
* `[value$="test"]` matches all the nodes whose `value` attribute ends with the string "test"
* `[value>2]` matches all the nodes whose `value` attribute is greater than 2
* `[value>=2]` matches all the nodes whose `value` attribute is greater or equals to 2
* `[value<2]` matches all the nodes whose `value` attribute is lower than 2
* `[value<=2]` matches all the nodes whose `value` attribute is lower or equals to 2
In attributes filters the type is very important because a selector like `[value="2"]` will match a node whose `value` attribute is the string "2" but not 2 as number.
Available types are:
* Strings: `[value="a"]` or `[value='a']`
* Integer numbers: `[value=123]` or `[value=0xFFF]` or `[value=0b11011]` or `[value=0o77]`
* Decimal numbers: `[value=1.23]`
* Booleans: `[value=true]` or `[value=false]`
* Null: `[value=null]`
Strings can be escaped using the backslash character, for example `[value='That\'s great']` will find a value that equals to the string "That's great".
You can perform case-insensitive comparison using this syntax `[value='search' i]`.
You can also search using a regexp in this way: `[value=/test\d+/i]`.
Sometimes it's useful to check also inner attributes, you can do it by separating attributes name with a dot.
For example `FunctionDeclaration[id.name='funcName']` matches all `FunctionDeclaration` whose `id` attribute has a `name` attribute with the value "funcName".
### Filter by pseudo selector
Pseudo selectors begin with `:` and can optionally accept arguments wrapped in parentheses.
There are 3 groups of pseudo selectors:
###### Simple pseudo selector
These selectors don't accept any argument.
* `:first-child` matches nodes that are the first child of their parent
* `:last-child` matches nodes that are the first child of their parent
* `:pattern` matches nodes that implement the `Pattern` interface
* `:statement` matches nodes that implement the `Statement` interface
* `:expression` matches nodes that implement the `Expression` interface
* `:declaration` matches nodes that implement the `Declaration` interface
###### Positional pseudo selector
These selectors accept a number or a An+B syntax, where A represents the step and B is the starting offset.
Remember that the index is 1-based, so the first node is 1.
You can read more about the arguments accepted by these select on [MDN](https://developer.mozilla.org/en-US/docs/Web/CSS/:nth-child).
* `:nth-child` matches nodes that respects the given index in their parent children list. For example: `:nth-child(5n+3)` matches every 5th node starting from the 3rd one.
* `:nth-last-child` matches nodes that respects the given index in their parent children list, starting from the end. For example: `:nth-last-child(1)` matches a node that is the last child of its parent.
You can also use `even` and `odd` as arguments to match even and odds nodes.
###### Inner selector pseudo selector
These selectors accept a inner selector.
* `:is` matches a node that respect the given selector. For example `Literal:is([value=2], [value=3])` matches `Literal` nodes whose `value` is 2 or 3
* `:not` matches a node that do not respect the given selector. For example `Literal:not([value=2], [value=3])` matches `Literal` nodes whose `value` is not 2 or 3
* `:has` matches a node whose descendant match the given selector. For example `AssignmentExpression:has(Literal[value="string""])` matches `AssignmentExpression` nodes that contain `Literal` nodes whose `value` is "string"
### Combinators
Combinators are used for match other nodes relative to the current.
* Descendant: the space can be used to match descendant nodes. For example `AssignmentExpression Literal` matches `Literal` nodes inside `AssignmentExpression` nodes, even if they are not direct children
* Children: the `>` character can be used to match child nodes. For example `ArrayExpression > Literal` matches a `Literal` nodes that are children of `ArrayExpression` nodes
* Adjacent Sibling: the `+` character can be used to match nodes that follow other nodes. For example `FunctionDeclaration + VariableDeclaration` matches the first `VariableDeclaration` nodes that follow `FunctionDeclaration` nodes
* General Sibling: the `~` character can be used to match all the nodes that follow other nodes. For example `FunctionDeclaration ~ VariableDeclaration` matches all the `VariableDeclaration` nodes that follow `FunctionDeclaration` nodes
### Groups
A selector can contain multiple selector groups separated by commas.
For example: `Literal, ArrayExpression` match all the `Literal` and `ArrayExpression` nodes.

Rendering
==========
**_From version 1.2_**
To render an AST generated by Peast you need to create an instance of the **Renderer** class and associate a **Formatter** to it:
```php
$source = "var a;";
//Generate the AST
$ast = Peast\Peast::latest($source, $options)->parse();
//Create the renderer
$renderer = new Peast\Renderer;
//Associate the formatter
$renderer->setFormatter(new Peast\Formatter\PrettyPrint);
//Render the AST
echo $renderer->render($ast); //"var a;"
```
Formatters
-------------
A Formatter specifies how the Renderer must format the nodes to produce the output.
Peast implements 3 formatters: **PrettyPrint**, **Compact** and **Expanded**.
For example using this source code:
```js
if (fn(param)) alert("Ok");
else alert("Fail");
```
##### PrettyPrint
Produces a well formatted version of the code.
```js
if (fn(param)) {
alert("Ok");
} else {
alert("Fail");
}
```
##### Compact
Produces a compact version of the code by removing whitespaces and optional brackets.
```js
if (fn(param))alert("Ok");else alert("Fail");
```
##### Expanded
An expanded version of PrettyPrint.
```js
if ( fn( param ) )
{
alert( "Ok" );
} else
{
alert( "Fail" );
}
```
Custom Formatter
-------------
Peast allows you to create your own formatter.
You can do it by creating a class that extends `Peast\Formatter\Base` class and overwriting its protected properties:
```php
class MyFormatter extends Peast\Formatter\Base {
//Use Windows style line endings
protected $newLine = "\r\n";
}
$renderer = new Peast\Renderer;
$renderer->setFormatter(new MyFormatter);
echo $renderer->render($ast);
```
Available properties are:
* `$newLine`: line separator string (default: `"\n"`)
* `$indentation`: indentation string (default: `"\t"`)
* `$newLineBeforeCurlyBracket`: if true, open curly brackets of code blocks will be put on a new line (default: `false`)
* `$alwaysWrapBlocks`: if true, curly brackets around code blocks will always be inserted, also when they are optional (default: `true`)
* `$spacesAroundOperators`: if true, a space will be inserted before and after operators (default: `true`)
* `$spacesInsideRoundBrackets`: if true, content inside round brackets will be surrounded by spaces (default: `false`)
Shortcut method
-------------
Every syntax node has its own `render` method that you can use as a shortcut.
For example:
```php
$ast = Peast\Peast::latest($source, $options)->parse();
$ast->render(new Peast\Formatter\PrettyPrint);
//Equivalent to
$ast = Peast\Peast::latest($source, $options)->parse();
$renderer = new Peast\Renderer;
$renderer->setFormatter(new Peast\Formatter\PrettyPrint);
$renderer->render($ast);
```
Comments rendering
-------------
**_From version 1.14_**
Comments can be rendered by passing `true` to the formatter constructor:
```php
$ast = Peast\Peast::latest($source, array("comments" => true))->parse();
$ast->render(new Peast\Formatter\PrettyPrint(true));
```
Note that comments can be rendered only when parser is enabled to collect them, to do this you must set the `comments` option to `true`.
Also note that only PrettyPrint and Expanded formatters allow comments rendering, while Compact does not allow it by default.

Tree Traversing
==========
**_From version 1.1_**
To traverse an AST generated by Peast you can use the **Traverser** class:
```php
//Generate the AST
$ast = Peast\Peast::latest($source, $options)->parse();
//Set up the Traverser
$traverser = new Peast\Traverser;
$traverser->addFunction(function ($node) {
//Do something with the current node
});
//Start traversing
$traverser->traverse($ast);
```
You can add one or more functions to the Traverser using the `addFunction` method. These functions receive the current traversed node while the Traverser runs on the tree.
The `traverse` method runs the traversing starting from the given node.
Options
-------------
**_From version 1.12_**
The Traverser class constructor takes an optional associative array of options.
Available options are:
* "skipStartingNode": by default the traversing begins with the starting node passed to the `traverse` method. If this option is set to true the starting node will be ignored.
* "passParentNode": by default the functions added to the Traverser receive the traversed node as the only argument. if this option is set to true the node's parent node will be passed as second argument to all the functions. Note that the parent node is calculated during traversing, so for the starting node it will always be null.
Tree manipulation
-------------
Functions added to the Traverser instance can alter the tree during the traversing by modifying, replacing or removing the node they receive and they can also control the behaviour of the Traverser to make it stop or skip the node's children.
Traverser class provides some constants to perform these operations:
* `Traverser::REMOVE_NODE`: removes the node
* `Traverser::DONT_TRAVERSE_CHILD_NODES`: skips the node's children
* `Traverser::STOP_TRAVERSING`: stops the traversing
The action that will be executed depends on the value returned by the functions.
If you want to remove a node the function must return the `Traverser::REMOVE_NODE` constant:
```php
$traverser->addFunction(function ($node) {
//Remove all literal nodes
if ($node->getType() === "Literal") {
return Peast\Traverser::REMOVE_NODE;
}
});
```
If you want to control the traversing you can return `Traverser::DONT_TRAVERSE_CHILD_NODES` or `Traverser::STOP_TRAVERSING` constants:
```php
$traverser->addFunction(function ($node) {
//Skip nodes inside array expressions
if ($node->getType() === "ArrayExpression") {
return Peast\Traverser::DONT_TRAVERSE_CHILD_NODES;
}
//Stop the traversing when an identifier named "stop" is found
elseif ($node->getType() === "Identifier" && $node->getName() === "stop") {
return Peast\Traverser::STOP_TRAVERSING;
}
});
```
You can also return a combination of these constants:
```php
$traverser->addFunction(function ($node) {
//Remove the string "test" and then stop the traversing
if ($node->getType() === "Literal" && $node->getValue() === "test") {
return Peast\Traverser::REMOVE_NODE | Peast\Traverser::STOP_TRAVERSING;
}
});
```
To replace a node you must return the replacement node:
```php
$traverser->addFunction(function ($node) {
//Replace the number 2 with 1
if ($node->getType() === "Literal" && $node->getValue() === 2) {
$literal = new \Peast\Syntax\Node\NumericLiteral();
return $literal->setValue(1);
}
});
```
You can also control the traversing and replace a node in the same function:
```php
$traverser->addFunction(function ($node) {
//Replace an array expression with an object expression without traversing its children
if ($node->getType() === "ArrayExpression") {
$obj = new \Peast\Syntax\Node\ObjectExpression();
return array($obj, Peast\Traverser::DONT_TRAVERSE_CHILD_NODES);
}
});
```
If the function returns any other value or nothing, no action will be executed and you can modify nodes without altering the tree structure:
```php
use Peast\Syntax\Node\StringLiteral;
$traverser->addFunction(function ($node) {
//Make all the strings uppercase
if ($node->getType() === "Literal" && $node instanceof StringLiteral) {
$node->setValue(strtoupper($node->getValue()));
}
});
```
Shortcut method
-------------
Every node implements a `traverse` method as a shortcut to initialize a traverser on itself:
```php
$traversingFn = function ($node) { /* ... */ };
//Traverse $ast node
$ast->traverse($traversingFn, $options);
//Equivalent to
$traverser = new Peast\Traverser;
$traverser->addFunction($traversingFn)->traverse($ast);
```
