# ESLint Scope
|
|
|
|
ESLint Scope is the [ECMAScript](http://www.ecma-international.org/publications/standards/Ecma-262.htm) scope analyzer used in ESLint. It is a fork of [escope](http://github.com/estools/escope).
|
|
|
|
## Usage
|
|
|
|
Install:
|
|
|
|
```
|
|
npm i eslint-scope --save
|
|
```
|
|
|
|
Example:
|
|
|
|
```js
|
|
var eslintScope = require('eslint-scope');
|
|
var espree = require('espree');
|
|
var estraverse = require('estraverse');
|
|
|
|
var ast = espree.parse(code);
|
|
var scopeManager = eslintScope.analyze(ast);
|
|
|
|
var currentScope = scopeManager.acquire(ast); // global scope
|
|
|
|
estraverse.traverse(ast, {
|
|
enter: function(node, parent) {
|
|
// do stuff
|
|
|
|
if (/Function/.test(node.type)) {
|
|
currentScope = scopeManager.acquire(node); // get current function scope
|
|
}
|
|
},
|
|
leave: function(node, parent) {
|
|
if (/Function/.test(node.type)) {
|
|
currentScope = currentScope.upper; // set to parent scope
|
|
}
|
|
|
|
// do stuff
|
|
}
|
|
});
|
|
```
