+# AST Types ![CI](https://github.com/benjamn/ast-types/workflows/CI/badge.svg)
+
+This module provides an efficient, modular,
+[Esprima](https://github.com/ariya/esprima)-compatible implementation of
+the [abstract syntax
+tree](http://en.wikipedia.org/wiki/Abstract_syntax_tree) type hierarchy
+pioneered by the [Mozilla Parser
+API](https://developer.mozilla.org/en-US/docs/SpiderMonkey/Parser_API).
+
+Installation
+---
+
+From NPM:
+
+    npm install ast-types
+
+From GitHub:
+
+    cd path/to/node_modules
+    git clone git://github.com/benjamn/ast-types.git
+    cd ast-types
+    npm install .
+
+Basic Usage
+---
+```js
+import assert from "assert";
+import {
+  namedTypes as n,
+  builders as b,
+} from "ast-types";
+
+var fooId = b.identifier("foo");
+var ifFoo = b.ifStatement(fooId, b.blockStatement([
+  b.expressionStatement(b.callExpression(fooId, []))
+]));
+
+assert.ok(n.IfStatement.check(ifFoo));
+assert.ok(n.Statement.check(ifFoo));
+assert.ok(n.Node.check(ifFoo));
+
+assert.ok(n.BlockStatement.check(ifFoo.consequent));
+assert.strictEqual(
+  ifFoo.consequent.body[0].expression.arguments.length,
+  0,
+);
+
+assert.strictEqual(ifFoo.test, fooId);
+assert.ok(n.Expression.check(ifFoo.test));
+assert.ok(n.Identifier.check(ifFoo.test));
+assert.ok(!n.Statement.check(ifFoo.test));
+```
+
+AST Traversal
+---
+
+Because it understands the AST type system so thoroughly, this library
+is able to provide excellent node iteration and traversal mechanisms.
+
+If you want complete control over the traversal, and all you need is a way
+of enumerating the known fields of your AST nodes and getting their
+values, you may be interested in the primitives `getFieldNames` and
+`getFieldValue`:
+```js
+import {
+  getFieldNames,
+  getFieldValue,
+} from "ast-types";
+
+const partialFunExpr = { type: "FunctionExpression" };
+
+// Even though partialFunExpr doesn't actually contain all the fields that
+// are expected for a FunctionExpression, types.getFieldNames knows:
+console.log(getFieldNames(partialFunExpr));
+// [ 'type', 'id', 'params', 'body', 'generator', 'expression',
+//   'defaults', 'rest', 'async' ]
+
+// For fields that have default values, types.getFieldValue will return
+// the default if the field is not actually defined.
+console.log(getFieldValue(partialFunExpr, "generator"));
+// false
+```
+
+Two more low-level helper functions, `eachField` and `someField`, are
+defined in terms of `getFieldNames` and `getFieldValue`:
+```js
+// Iterate over all defined fields of an object, including those missing
+// or undefined, passing each field name and effective value (as returned
+// by getFieldValue) to the callback. If the object has no corresponding
+// Def, the callback will never be called.
+export function eachField(object, callback, context) {
+  getFieldNames(object).forEach(function(name) {
+    callback.call(this, name, getFieldValue(object, name));
+  }, context);
+}
+
+// Similar to eachField, except that iteration stops as soon as the
+// callback returns a truthy value. Like Array.prototype.some, the final
+// result is either true or false to indicates whether the callback
+// returned true for any element or not.
+export function someField(object, callback, context) {
+  return getFieldNames(object).some(function(name) {
+    return callback.call(this, name, getFieldValue(object, name));
+  }, context);
+}
+```
+
+So here's how you might make a copy of an AST node:
+```js
+import { eachField } from "ast-types";
+const copy = {};
+eachField(node, function(name, value) {
+  // Note that undefined fields will be visited too, according to
+  // the rules associated with node.type, and default field values
+  // will be substituted if appropriate.
+  copy[name] = value;
+})
+```
+
+But that's not all! You can also easily visit entire syntax trees using
+the powerful `types.visit` abstraction.
+
+Here's a trivial example of how you might assert that `arguments.callee`
+is never used in `ast`:
+```js
+import assert from "assert";
+import {
+  visit,
+  namedTypes as n,
+} from "ast-types";
+
+visit(ast, {
+  // This method will be called for any node with .type "MemberExpression":
+  visitMemberExpression(path) {
+    // Visitor methods receive a single argument, a NodePath object
+    // wrapping the node of interest.
+    var node = path.node;
+
+    if (
+      n.Identifier.check(node.object) &&
+      node.object.name === "arguments" &&
+      n.Identifier.check(node.property)
+    ) {
+      assert.notStrictEqual(node.property.name, "callee");
+    }
+
+    // It's your responsibility to call this.traverse with some
+    // NodePath object (usually the one passed into the visitor
+    // method) before the visitor method returns, or return false to
+    // indicate that the traversal need not continue any further down
+    // this subtree.
+    this.traverse(path);
+  }
+});
+```
+
+Here's a slightly more involved example of transforming `...rest`
+parameters into browser-runnable ES5 JavaScript:
+
+```js
+import { builders as b, visit } from "ast-types";
+
+// Reuse the same AST structure for Array.prototype.slice.call.
+var sliceExpr = b.memberExpression(
+  b.memberExpression(
+    b.memberExpression(
+      b.identifier("Array"),
+      b.identifier("prototype"),
+      false
+    ),
+    b.identifier("slice"),
+    false
+  ),
+  b.identifier("call"),
+  false
+);
+
+visit(ast, {
+  // This method will be called for any node whose type is a subtype of
+  // Function (e.g., FunctionDeclaration, FunctionExpression, and
+  // ArrowFunctionExpression). Note that types.visit precomputes a
+  // lookup table from every known type to the appropriate visitor
+  // method to call for nodes of that type, so the dispatch takes
+  // constant time.
+  visitFunction(path) {
+    // Visitor methods receive a single argument, a NodePath object
+    // wrapping the node of interest.
+    const node = path.node;
+
+    // It's your responsibility to call this.traverse with some
+    // NodePath object (usually the one passed into the visitor
+    // method) before the visitor method returns, or return false to
+    // indicate that the traversal need not continue any further down
+    // this subtree. An assertion will fail if you forget, which is
+    // awesome, because it means you will never again make the
+    // disastrous mistake of forgetting to traverse a subtree. Also
+    // cool: because you can call this method at any point in the
+    // visitor method, it's up to you whether your traversal is
+    // pre-order, post-order, or both!
+    this.traverse(path);
+
+    // This traversal is only concerned with Function nodes that have
+    // rest parameters.
+    if (!node.rest) {
+      return;
+    }
+
+    // For the purposes of this example, we won't worry about functions
+    // with Expression bodies.
+    n.BlockStatement.assert(node.body);
+
+    // Use types.builders to build a variable declaration of the form
+    //
+    //   var rest = Array.prototype.slice.call(arguments, n);
+    //
+    // where `rest` is the name of the rest parameter, and `n` is a
+    // numeric literal specifying the number of named parameters the
+    // function takes.
+    const restVarDecl = b.variableDeclaration("var", [
+      b.variableDeclarator(
+        node.rest,
+        b.callExpression(sliceExpr, [
+          b.identifier("arguments"),
+          b.literal(node.params.length)
+        ])
+      )
+    ]);
+
+    // Similar to doing node.body.body.unshift(restVarDecl), except
+    // that the other NodePath objects wrapping body statements will
+    // have their indexes updated to accommodate the new statement.
+    path.get("body", "body").unshift(restVarDecl);
+
+    // Nullify node.rest now that we have simulated the behavior of
+    // the rest parameter using ordinary JavaScript.
+    path.get("rest").replace(null);
+
+    // There's nothing wrong with doing node.rest = null, but I wanted
+    // to point out that the above statement has the same effect.
+    assert.strictEqual(node.rest, null);
+  }
+});
+```
+
+Here's how you might use `types.visit` to implement a function that
+determines if a given function node refers to `this`:
+
+```js
+function usesThis(funcNode) {
+  n.Function.assert(funcNode);
+  var result = false;
+
+  visit(funcNode, {
+    visitThisExpression(path) {
+      result = true;
+
+      // The quickest way to terminate the traversal is to call
+      // this.abort(), which throws a special exception (instanceof
+      // this.AbortRequest) that will be caught in the top-level
+      // types.visit method, so you don't have to worry about
+      // catching the exception yourself.
+      this.abort();
+    },
+
+    visitFunction(path) {
+      // ThisExpression nodes in nested scopes don't count as `this`
+      // references for the original function node, so we can safely
+      // avoid traversing this subtree.
+      return false;
+    },
+
+    visitCallExpression(path) {
+      const node = path.node;
+
+      // If the function contains CallExpression nodes involving
+      // super, those expressions will implicitly depend on the
+      // value of `this`, even though they do not explicitly contain
+      // any ThisExpression nodes.
+      if (this.isSuperCallExpression(node)) {
+        result = true;
+        this.abort(); // Throws AbortRequest exception.
+      }
+
+      this.traverse(path);
+    },
+
+    // Yes, you can define arbitrary helper methods.
+    isSuperCallExpression(callExpr) {
+      n.CallExpression.assert(callExpr);
+      return this.isSuperIdentifier(callExpr.callee)
+          || this.isSuperMemberExpression(callExpr.callee);
+    },
+
+    // And even helper helper methods!
+    isSuperIdentifier(node) {
+      return n.Identifier.check(node.callee)
+          && node.callee.name === "super";
+    },
+
+    isSuperMemberExpression(node) {
+      return n.MemberExpression.check(node.callee)
+          && n.Identifier.check(node.callee.object)
+          && node.callee.object.name === "super";
+    }
+  });
+
+  return result;
+}
+```
+
+As you might guess, when an `AbortRequest` is thrown from a subtree, the
+exception will propagate from the corresponding calls to `this.traverse`
+in the ancestor visitor methods. If you decide you want to cancel the
+request, simply catch the exception and call its `.cancel()` method. The
+rest of the subtree beneath the `try`-`catch` block will be abandoned, but
+the remaining siblings of the ancestor node will still be visited.
+
+NodePath
+---
+
+The `NodePath` object passed to visitor methods is a wrapper around an AST
+node, and it serves to provide access to the chain of ancestor objects
+(all the way back to the root of the AST) and scope information.
+
+In general, `path.node` refers to the wrapped node, `path.parent.node`
+refers to the nearest `Node` ancestor, `path.parent.parent.node` to the
+grandparent, and so on.
+
+Note that `path.node` may not be a direct property value of
+`path.parent.node`; for instance, it might be the case that `path.node` is
+an element of an array that is a direct child of the parent node:
+```js
+path.node === path.parent.node.elements[3]
+```
+in which case you should know that `path.parentPath` provides
+finer-grained access to the complete path of objects (not just the `Node`
+ones) from the root of the AST:
+```js
+// In reality, path.parent is the grandparent of path:
+path.parentPath.parentPath === path.parent
+
+// The path.parentPath object wraps the elements array (note that we use
+// .value because the elements array is not a Node):
+path.parentPath.value === path.parent.node.elements
+
+// The path.node object is the fourth element in that array:
+path.parentPath.value[3] === path.node
+
+// Unlike path.node and path.value, which are synonyms because path.node
+// is a Node object, path.parentPath.node is distinct from
+// path.parentPath.value, because the elements array is not a
+// Node. Instead, path.parentPath.node refers to the closest ancestor
+// Node, which happens to be the same as path.parent.node:
+path.parentPath.node === path.parent.node
+
+// The path is named for its index in the elements array:
+path.name === 3
+
+// Likewise, path.parentPath is named for the property by which
+// path.parent.node refers to it:
+path.parentPath.name === "elements"
+
+// Putting it all together, we can follow the chain of object references
+// from path.parent.node all the way to path.node by accessing each
+// property by name:
+path.parent.node[path.parentPath.name][path.name] === path.node
+```
+
+These `NodePath` objects are created during the traversal without
+modifying the AST nodes themselves, so it's not a problem if the same node
+appears more than once in the AST (like `Array.prototype.slice.call` in
+the example above), because it will be visited with a distict `NodePath`
+each time it appears.
+
+Child `NodePath` objects are created lazily, by calling the `.get` method
+of a parent `NodePath` object:
+```js
+// If a NodePath object for the elements array has never been created
+// before, it will be created here and cached in the future:
+path.get("elements").get(3).value === path.value.elements[3]
+
+// Alternatively, you can pass multiple property names to .get instead of
+// chaining multiple .get calls:
+path.get("elements", 0).value === path.value.elements[0]
+```
+
+`NodePath` objects support a number of useful methods:
+```js
+// Replace one node with another node:
+var fifth = path.get("elements", 4);
+fifth.replace(newNode);
+
+// Now do some stuff that might rearrange the list, and this replacement
+// remains safe:
+fifth.replace(newerNode);
+
+// Replace the third element in an array with two new nodes:
+path.get("elements", 2).replace(
+  b.identifier("foo"),
+  b.thisExpression()
+);
+
+// Remove a node and its parent if it would leave a redundant AST node:
+//e.g. var t = 1, y =2; removing the `t` and `y` declarators results in `var undefined`.
+path.prune(); //returns the closest parent `NodePath`.
+
+// Remove a node from a list of nodes:
+path.get("elements", 3).replace();
+
+// Add three new nodes to the beginning of a list of nodes:
+path.get("elements").unshift(a, b, c);
+
+// Remove and return the first node in a list of nodes:
+path.get("elements").shift();
+
+// Push two new nodes onto the end of a list of nodes:
+path.get("elements").push(d, e);
+
+// Remove and return the last node in a list of nodes:
+path.get("elements").pop();
+
+// Insert a new node before/after the seventh node in a list of nodes:
+var seventh = path.get("elements", 6);
+seventh.insertBefore(newNode);
+seventh.insertAfter(newNode);
+
+// Insert a new element at index 5 in a list of nodes:
+path.get("elements").insertAt(5, newNode);
+```
+
+Scope
+---
+
+The object exposed as `path.scope` during AST traversals provides
+information about variable and function declarations in the scope that
+contains `path.node`. See [scope.ts](lib/scope.ts) for its public
+interface, which currently includes `.isGlobal`, `.getGlobalScope()`,
+`.depth`, `.declares(name)`, `.lookup(name)`, and `.getBindings()`.
+
+Custom AST Node Types
+---
+
+The `ast-types` module was designed to be extended. To that end, it
+provides a readable, declarative syntax for specifying new AST node types,
+based primarily upon the `require("ast-types").Type.def` function:
+```js
+import {
+  Type,
+  builtInTypes,
+  builders as b,
+  finalize,
+} from "ast-types";
+
+const { def } = Type;
+const { string } = builtInTypes;
+
+// Suppose you need a named File type to wrap your Programs.
+def("File")
+  .bases("Node")
+  .build("name", "program")
+  .field("name", string)
+  .field("program", def("Program"));
+
+// Prevent further modifications to the File type (and any other
+// types newly introduced by def(...)).
+finalize();
+
+// The b.file builder function is now available. It expects two
+// arguments, as named by .build("name", "program") above.
+const main = b.file("main.js", b.program([
+  // Pointless program contents included for extra color.
+  b.functionDeclaration(b.identifier("succ"), [
+    b.identifier("x")
+  ], b.blockStatement([
+    b.returnStatement(
+      b.binaryExpression(
+        "+", b.identifier("x"), b.literal(1)
+      )
+    )
+  ]))
+]));
+
+assert.strictEqual(main.name, "main.js");
+assert.strictEqual(main.program.body[0].params[0].name, "x");
+// etc.
+
+// If you pass the wrong type of arguments, or fail to pass enough
+// arguments, an AssertionError will be thrown.
+
+b.file(b.blockStatement([]));
+// ==> AssertionError: {"body":[],"type":"BlockStatement","loc":null} does not match type string
+
+b.file("lib/types.js", b.thisExpression());
+// ==> AssertionError: {"type":"ThisExpression","loc":null} does not match type Program
+```
+
+The `def` syntax is used to define all the default AST node types found in
+[babel-core.ts](def/babel-core.ts),
+[babel.ts](def/babel.ts),
+[core.ts](def/core.ts),
+[es-proposals.ts](def/es-proposals.ts),
+[es6.ts](def/es6.ts),
+[es7.ts](def/es7.ts),
+[es2020.ts](def/es2020.ts),
+[esprima.ts](def/esprima.ts),
+[flow.ts](def/flow.ts),
+[jsx.ts](def/jsx.ts),
+[type-annotations.ts](def/type-annotations.ts),
+and
+[typescripts.ts](def/typescripts.ts),
+so you have
+no shortage of examples to learn from.

+# tslib
+
+This is a runtime library for [TypeScript](https://www.typescriptlang.org/) that contains all of the TypeScript helper functions.
+
+This library is primarily used by the `--importHelpers` flag in TypeScript.
+When using `--importHelpers`, a module that uses helper functions like `__extends` and `__assign` in the following emitted file:
+
+```ts
+var __assign = (this && this.__assign) || Object.assign || function(t) {
+    for (var s, i = 1, n = arguments.length; i < n; i++) {
+        s = arguments[i];
+        for (var p in s) if (Object.prototype.hasOwnProperty.call(s, p))
+            t[p] = s[p];
+    }
+    return t;
+};
+exports.x = {};
+exports.y = __assign({}, exports.x);
+
+```
+
+will instead be emitted as something like the following:
+
+```ts
+var tslib_1 = require("tslib");
+exports.x = {};
+exports.y = tslib_1.__assign({}, exports.x);
+```
+
+Because this can avoid duplicate declarations of things like `__extends`, `__assign`, etc., this means delivering users smaller files on average, as well as less runtime overhead.
+For optimized bundles with TypeScript, you should absolutely consider using `tslib` and `--importHelpers`.
+
+# Installing
+
+For the latest stable version, run:
+
+## npm
+
+```sh
+# TypeScript 3.9.2 or later
+npm install tslib
+
+# TypeScript 3.8.4 or earlier
+npm install tslib@^1
+
+# TypeScript 2.3.2 or earlier
+npm install tslib@1.6.1
+```
+
+## yarn
+
+```sh
+# TypeScript 3.9.2 or later
+yarn add tslib
+
+# TypeScript 3.8.4 or earlier
+yarn add tslib@^1
+
+# TypeScript 2.3.2 or earlier
+yarn add tslib@1.6.1
+```
+
+## bower
+
+```sh
+# TypeScript 3.9.2 or later
+bower install tslib
+
+# TypeScript 3.8.4 or earlier
+bower install tslib@^1
+
+# TypeScript 2.3.2 or earlier
+bower install tslib@1.6.1
+```
+
+## JSPM
+
+```sh
+# TypeScript 3.9.2 or later
+jspm install tslib
+
+# TypeScript 3.8.4 or earlier
+jspm install tslib@^1
+
+# TypeScript 2.3.2 or earlier
+jspm install tslib@1.6.1
+```
+
+# Usage
+
+Set the `importHelpers` compiler option on the command line:
+
+```
+tsc --importHelpers file.ts
+```
+
+or in your tsconfig.json:
+
+```json
+{
+    "compilerOptions": {
+        "importHelpers": true
+    }
+}
+```
+
+#### For bower and JSPM users
+
+You will need to add a `paths` mapping for `tslib`, e.g. For Bower users:
+
+```json
+{
+    "compilerOptions": {
+        "module": "amd",
+        "importHelpers": true,
+        "baseUrl": "./",
+        "paths": {
+            "tslib" : ["bower_components/tslib/tslib.d.ts"]
+        }
+    }
+}
+```
+
+For JSPM users:
+
+```json
+{
+    "compilerOptions": {
+        "module": "system",
+        "importHelpers": true,
+        "baseUrl": "./",
+        "paths": {
+            "tslib" : ["jspm_packages/npm/tslib@2.x.y/tslib.d.ts"]
+        }
+    }
+}
+```
+
+## Deployment
+
+- Choose your new version number
+- Set it in `package.json` and `bower.json`
+- Create a tag: `git tag [version]`
+- Push the tag: `git push --tags`
+- Create a [release in GitHub](https://github.com/microsoft/tslib/releases)
+- Run the [publish to npm](https://github.com/microsoft/tslib/actions?query=workflow%3A%22Publish+to+NPM%22) workflow
+
+Done.
