-var partialFunExpr = { type: "FunctionExpression" }; - -// Even though partialFunExpr doesn't actually contain all the fields that -// are expected for a FunctionExpression, types.getFieldNames knows: -console.log(types.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(types.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. -exports.eachField = function(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. -exports.someField = function(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 -var copy = {}; -require("ast-types").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 -var assert = require("assert"); -var types = require("ast-types"); -var n = types.namedTypes; - -types.visit(ast, { - // This method will be called for any node with .type "MemberExpression": - visitMemberExpression: function(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 -var b = types.builders; - -// 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 -); - -types.visit(ast, { - // This method will be called for any node whose type is a subtype of - // Function (e.g., FunctionDeclaration, FunctionExpression, and - // ArrowFunctionExpression).

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. - var 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; - - types.visit(funcNode, { - visitThisExpression: function(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: function(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: function(path) { - var 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: function(callExpr) { - n.CallExpression.assert(callExpr); - return this.isSuperIdentifier(callExpr.callee) - || this.isSuperMemberExpression(callExpr.callee); - }, - - // And even helper helper methods! - isSuperIdentifier: function(node) { - return n.Identifier.check(node.callee) - && node.callee.name === "super"; - }, - - isSuperMemberExpression: function(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.js](lib/scope.js) 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 -var types = require("ast-types"); -var def = types.Type.def; -var string = types.builtInTypes.string; -var b = types.builders; - -// 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(...)). -types.finalize(); - -// The b.file builder function is now available.

- -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([]));
