Espree is now built on top of [Acorn](https://github.com/ternjs/acorn), which has a modular architecture that allows extension of core functionality. The goal of Espree is to produce output that is similar to Esprima with a similar API so that it can be used in place of Esprima.\n\n## Usage\n\nInstall:\n\n```\nnpm i espree --save\n```\n\nAnd in your Node.js code:\n\n```javascript\nvar espree = require(\"espree\");\n\nvar ast = espree.parse(code);\n```\n\nThere is a second argument to `parse()` that allows you to specify various options:\n\n```javascript\nvar espree = require(\"espree\");\n\nvar ast = espree.parse(code, {\n\n    // attach range information to each node\n    range: true,\n\n    // attach line/column location information to each node\n    loc: true,\n\n    // create a top-level comments array containing all comments\n    comment: true,\n\n    // attach comments to the closest relevant node as leadingComments and\n    // trailingComments\n    attachComment: true,\n\n    // create a top-level tokens array containing all tokens\n    tokens: true,\n\n    // set to 3, 5 (default), 6, 7, or 8 to specify the version of ECMAScript syntax you want to use. \n    // You can also set to 2015 (same as 6), 2016 (same as 7), or 2017 (same as 8) to use the year-based naming.\n    ecmaVersion: 5,\n\n    // specify which type of script you're parsing (script or module, default is script)\n    sourceType: \"script\",\n\n    // specify additional language features\n    ecmaFeatures: {\n\n        // enable JSX parsing\n        jsx: true,\n\n        // enable return in global scope\n        globalReturn: true,\n\n        // enable implied strict mode (if ecmaVersion >= 5)\n        impliedStrict: true,\n\n        // allow experimental object rest/spread\n        experimentalObjectRestSpread: true\n    }\n});\n```\n\n## Esprima Compatibility Going Forward\n\nThe primary goal is to produce the exact same AST structure and tokens as Esprima, and that takes precedence over anything else. (The AST structure being the [ESTree](https://github.com/estree/estree) API with JSX extensions.) Separate from that, Espree may deviate from what Esprima outputs in terms of where and how comments are attached, as well as what additional information is available on AST nodes. That is to say, Espree may add more things to the AST nodes than Esprima does but the overall AST structure produced will be the same.\n\nEspree may also deviate from Esprima in the interface it exposes.\n\n## Contributing\n\nIssues and pull requests will be triaged and responded to as quickly as possible. We operate under the [ESLint Contributor Guidelines](http://eslint.org/docs/developer-guide/contributing), so please be sure to read them before contributing. If you're not sure where to dig in, check out the [issues](https://github.com/eslint/espree/issues).\n\nEspree is licensed under a permissive BSD 2-clause license.\n\n## Build Commands\n\n* `npm test` - run all linting and tests\n* `npm run lint` - run all linting\n* `npm run browserify` - creates a version of Espree that is usable in a browser\n\n## Differences from Espree 2.x\n\n* The `tokenize()` method does not use `ecmaFeatures`. Any string will be tokenized completely based on ECMAScript 6 semantics.\n* Trailing whitespace no longer is counted as part of a node.\n* `let` and `const` declarations are no longer parsed by default. You must opt-in using `ecmaFeatures.blockBindings`.\n* The `esparse` and `esvalidate` binary scripts have been removed.\n* There is no `tolerant` option. We will investigate adding this back in the future.\n\n## Known Incompatibilities\n\nIn an effort to help those wanting to transition from other parsers to Espree, the following is a list of noteworthy incompatibilities with other parsers. These are known differences that we do not intend to change.\n\n### Esprima 1.2.2\n\n* Esprima counts trailing whitespace as part of each AST node while Espree does not. In Espree, the end of a node is where the last token occurs.\n* Espree does not parse `let` and `const` declarations by default.\n* Error messages returned for parsing errors are different.\n* There are two addition properties on every node and token: `start` and `end`. These represent the same data as `range` and are used internally by Acorn.\n\n### Esprima 2.x\n\n* Esprima 2.x uses a different comment attachment algorithm that results in some comments being added in different places than Espree. The algorithm Espree uses is the same one used in Esprima 1.2.2.\n\n## Frequently Asked Questions\n\n### Why another parser\n\n[ESLint](http://eslint.org) had been relying on Esprima as its parser from the beginning. While that was fine when the JavaScript language was evolving slowly, the pace of development increased dramatically and Esprima had fallen behind. ESLint, like many other tools reliant on Esprima, has been stuck in using new JavaScript language features until Esprima updates, and that caused our users frustration.\n\nWe decided the only way for us to move forward was to create our own parser, bringing us inline with JSHint and JSLint, and allowing us to keep implementing new features as we need them. We chose to fork Esprima instead of starting from scratch in order to move as quickly as possible with a compatible API.\n\nWith Espree 2.0.0, we are no longer a fork of Esprima but rather a translation layer between Acorn and Esprima syntax. This allows us to put work back into a community-supported parser (Acorn) that is continuing to grow and evolve while maintaining an Esprima-compatible parser for those utilities still built on Esprima.\n\n### Have you tried working with Esprima?\n\nYes. Since the start of ESLint, we've regularly filed bugs and feature requests with Esprima and will continue to do so. However, there are some different philosophies around how the projects work that need to be worked through. The initial goal was to have Espree track Esprima and eventually merge the two back together, but we ultimately decided that building on top of Acorn was a better choice due to Acorn's plugin support.\n\n### Why don't you just use Acorn?\n\nAcorn is a great JavaScript parser that produces an AST that is compatible with Esprima. Unfortunately, ESLint relies on more than just the AST to do its job. It relies on Esprima's tokens and comment attachment features to get a complete picture of the source code. We investigated switching to Acorn, but the inconsistencies between Esprima and Acorn created too much work for a project like ESLint.\n\nWe are building on top of Acorn, however, so that we can contribute back and help make Acorn even better.\n\n### What ECMAScript 6 features do you support?\n\nAll of them.\n\n### What ECMAScript 7/2016 features do you support?\n\nThere is only one ECMAScript 7 syntax change: the exponentiation operator. Espree supports this.\n\n### What ECMAScript 2017 features do you support?\n\nBecause ECMAScript 2017 is still under development, we are implementing features as they are finalized. Currently, Espree supports:\n\n* `async` functions\n* Trailing commas in function declarations and calls (including arrow functions and concise methods)\n\n### How do you determine which experimental features to support?\n\nIn general, we do not support experimental JavaScript features. We may make exceptions from time to time depending on the maturity of the features.\n",readmeFilename:"README.md",repository:{type:"git",url:"git+https://github.com/eslint/espree.git"},scripts:{alpharelease:"eslint-prelease alpha",betarelease:"eslint-prelease

The available options are:\n\n* `unwrap` - set to `true` to delete the leading `/**`, any `*` that begins a line, and the trailing `*/` from the source text. Default: `false`.\n* `tags` - an array of tags to return. When specified, Doctrine returns only tags in this array. For example, if `tags` is `["param"]`, then only `@param` tags will be returned. Default: `null`.\n* `recoverable` - set to `true` to keep parsing even when syntax errors occur. Default: `false`.\n* `sloppy` - set to `true` to allow optional parameters to be specified in brackets (`@param {string} [foo]`). Default: `false`.\n* `lineNumbers` - set to `true` to add `lineNumber` to each node, specifying the line on which the node is found in the source. Default: `false`.\n\nHere\'s a simple example:\n\n```js\nvar ast = doctrine.parse(\n    [\n        "/**",\n        " * This function comment is parsed by doctrine",\n        " * @param {{ok:String}} userName",\n        "*/"\n    ].join(\'\\n\'), { unwrap: true });\n```\n\nThis example returns the following AST:\n\n    {\n        "description": "This function comment is parsed by doctrine",\n        "tags": [\n            {\n                "title": "param",\n                "description": null,\n                "type": {\n                    "type": "RecordType",\n                    "fields": [\n                        {\n                            "type": "FieldType",\n                            "key": "ok",\n                            "value": {\n                                "type": "NameExpression",\n                                "name": "String"\n                            }\n                        }\n                    ]\n                },\n                "name": "userName"\n            }\n        ]\n    }\n\nSee the [demo page](http://eslint.org/doctrine/demo/) more detail.\n\n## Team\n\nThese folks keep the project moving and are resources for help:\n\n* Nicholas C.

We operate under the [ESLint Contributor Guidelines](http://eslint.org/docs/developer-guide/contributing), so please be sure to read them before contributing. If you\'re not sure where to dig in, check out the [issues](https://github.com/eslint/doctrine/issues).\n\n## Frequently Asked Questions\n\n### Can I pass a whole JavaScript file to Doctrine?\n\nNo. Doctrine can only parse JSDoc comments, so you\'ll need to pass just the JSDoc comment to Doctrine in order to work.\n\n\n### License\n\n#### doctrine\n\nCopyright JS Foundation and other contributors, https://js.foundation\n\nLicensed under the Apache License, Version 2.0 (the "License");\nyou may not use this file except in compliance with the License.\nYou may obtain a copy of the License at\n\n    http://www.apache.org/licenses/LICENSE-2.0\n\nUnless required by applicable law or agreed to in writing, software\ndistributed under the License is distributed on an "AS IS" BASIS,\nWITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.\nSee the License for the specific language governing permissions and\nlimitations under the License.\n\n#### esprima\n\nsome of functions is derived from esprima\n\nCopyright (C) 2012, 2011 [Ariya Hidayat](http://ariya.ofilabs.com/about)\n (twitter: [@ariyahidayat](http://twitter.com/ariyahidayat)) and other contributors.\n\nRedistribution and use in source and binary forms, with or without\nmodification, are permitted provided that the following conditions are met:\n\n  * Redistributions of source code must retain the above copyright\n    notice, this list of conditions and the following disclaimer.\n\n  * Redistributions in binary form must reproduce the above copyright\n    notice, this list of conditions and the following disclaimer in the\n    documentation and/or other materials provided with the distribution.\n\nTHIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS "AS IS"\nAND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE\nIMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE\nARE DISCLAIMED.

Status](https://travis-ci.org/estools/esrecurse.svg?branch=master)](https://travis-ci.org/estools/esrecurse)\n\nEsrecurse ([esrecurse](https://github.com/estools/esrecurse)) is\n[ECMAScript](https://www.ecma-international.org/publications/standards/Ecma-262.htm)\nrecursive traversing functionality.\n\n### Example Usage\n\nThe following code will output all variables declared at the root of a file.\n\n```javascript\nesrecurse.visit(ast, {\n    XXXStatement: function (node) {\n        this.visit(node.left);\n        // do something...\n        this.visit(node.right);\n    }\n});\n```\n\nWe can use `Visitor` instance.\n\n```javascript\nvar visitor = new esrecurse.Visitor({\n    XXXStatement: function (node) {\n        this.visit(node.left);\n        // do something...\n        this.visit(node.right);\n    }\n});\n\nvisitor.visit(ast);\n```\n\nWe can inherit `Visitor` instance easily.\n\n```javascript\nclass Derived extends esrecurse.Visitor {\n    constructor()\n    {\n        super(null);\n    }\n\n    XXXStatement(node) {\n    }\n}\n\n```javascript\nfunction DerivedVisitor() {\n    esrecurse.Visitor.call(/* this for constructor */  this  /* visitor object automatically becomes this. */);\n}\nutil.inherits(DerivedVisitor, esrecurse.Visitor);\nDerivedVisitor.prototype.XXXStatement = function (node) {\n    this.visit(node.left);\n    // do something...\n    this.visit(node.right);\n};\n```\n\nAnd you can invoke default visiting operation inside custom visit operation.\n\n```javascript\nfunction DerivedVisitor() {\n    esrecurse.Visitor.call(/* this for constructor */  this  /* visitor object automatically becomes this. */);\n}\nutil.inherits(DerivedVisitor, esrecurse.Visitor);\nDerivedVisitor.prototype.XXXStatement = function (node) {\n    // do something...\n    this.visitChildren(node);\n};\n```\n\nThe `childVisitorKeys` option does customize the behavoir of `this.visitChildren(node)`.\nWe can use user-defined node types.\n\n```javascript\n// This tree contains a user-defined `TestExpression` node.\nvar tree = {\n    type: 'TestExpression',\n\n    // This 'argument' is the property containing the other **node**.\n    argument: {\n        type: 'Literal',\n        value: 20\n    },\n\n    // This 'extended' is the property not containing the other **node**.\n    extended: true\n};\nesrecurse.visit(\n    ast,\n    {\n        Literal: function (node) {\n            // do something...\n        }\n    },\n    {\n        // Extending the existing traversing rules.\n        childVisitorKeys: {\n            // TargetNodeName: [ 'keys', 'containing', 'the', 'other', '**node**' ]\n            TestExpression: ['argument']\n        }\n    }\n);\n```\n\nWe can use the `fallback` option as well.\nIf the `fallback` option is `\"iteration\"`, `esrecurse` would visit all enumerable properties of unknown nodes.\nPlease note circular references cause the stack overflow. AST might have circular references in additional properties for some purpose (e.g. `node.parent`).\n\n```javascript\nesrecurse.visit(\n    ast,\n    {\n        Literal: function (node) {\n            // do something...\n        }\n    },\n    {\n        fallback: 'iteration'\n    }\n);\n```\n\nIf the `fallback` option is a function, `esrecurse` calls this function to determine the enumerable properties of unknown nodes.\nPlease note circular references cause the stack overflow. AST might have circular references in additional properties for some purpose (e.g. `node.parent`).\n\n```javascript\nesrecurse.visit(\n    ast,\n    {\n        Literal: function (node) {\n            // do something...\n        }\n    },\n    {\n        fallback: function (node) {\n            return Object.keys(node).filter(function(key) {\n                return key !== 'argument'\n            });\n        }\n    }\n);\n```\n\n### License\n\nCopyright (C) 2014 [Yusuke Suzuki](https://github.com/Constellation)\n (twitter: [@Constellation](https://twitter.com/Constellation)) and other contributors.\n\nRedistribution and use in source and binary forms, with or without\nmodification, are permitted provided that the following conditions are met:\n\n  * Redistributions of source code must retain the above copyright\n    notice, this list of conditions and the following disclaimer.\n\n  * Redistributions in binary form must reproduce the above copyright\n    notice, this list of conditions and the following disclaimer in the\n    documentation and/or other materials provided with the distribution.\n\nTHIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS \"AS IS\"\nAND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE\nIMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE\nARE DISCLAIMED.

The available options are:\n\n* `unwrap` - set to `true` to delete the leading `/**`, any `*` that begins a line, and the trailing `*/` from the source text. Default: `false`.\n* `tags` - an array of tags to return. When specified, Doctrine returns only tags in this array. For example, if `tags` is `["param"]`, then only `@param` tags will be returned. Default: `null`.\n* `recoverable` - set to `true` to keep parsing even when syntax errors occur. Default: `false`.\n* `sloppy` - set to `true` to allow optional parameters to be specified in brackets (`@param {string} [foo]`). Default: `false`.\n* `lineNumbers` - set to `true` to add `lineNumber` to each node, specifying the line on which the node is found in the source. Default: `false`.\n\nHere\'s a simple example:\n\n```js\nvar ast = doctrine.parse(\n    [\n        "/**",\n        " * This function comment is parsed by doctrine",\n        " * @param {{ok:String}} userName",\n        "*/"\n    ].join(\'\\n\'), { unwrap: true });\n```\n\nThis example returns the following AST:\n\n    {\n        "description": "This function comment is parsed by doctrine",\n        "tags": [\n            {\n                "title": "param",\n                "description": null,\n                "type": {\n                    "type": "RecordType",\n                    "fields": [\n                        {\n                            "type": "FieldType",\n                            "key": "ok",\n                            "value": {\n                                "type": "NameExpression",\n                                "name": "String"\n                            }\n                        }\n                    ]\n                },\n                "name": "userName"\n            }\n        ]\n    }\n\nSee the [demo page](http://eslint.org/doctrine/demo/) more detail.\n\n## Team\n\nThese folks keep the project moving and are resources for help:\n\n* Nicholas C.
