    ESLint Scope

    ESLint Scope is the ECMAScript scope analyzer used in ESLint. It is a fork of escope.

    Usage

    Install:

    npm i eslint-scope --save
    

    Example:

    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
        }
    });
