# Acorn
|
||||
|
||||
[](https://travis-ci.org/marijnh/acorn)
|
||||
[](https://www.npmjs.org/package/acorn)
|
||||
[Author funding status: ](https://marijnhaverbeke.nl/fund/)
|
||||
|
||||
A tiny, fast JavaScript parser, written completely in JavaScript.
|
||||
|
||||
## Installation
|
||||
|
||||
The easiest way to install acorn is with [`npm`][npm].
|
||||
|
||||
[npm]: http://npmjs.org
|
||||
|
||||
```sh
|
||||
npm install acorn
|
||||
```
|
||||
|
||||
Alternately, download the source.
|
||||
|
||||
```sh
|
||||
git clone https://github.com/marijnh/acorn.git
|
||||
```
|
||||
|
||||
## Components
|
||||
|
||||
When run in a CommonJS (node.js) or AMD environment, exported values
|
||||
appear in the interfaces exposed by the individual files, as usual.
|
||||
When loaded in the browser (Acorn works in any JS-enabled browser more
|
||||
recent than IE5) without any kind of module management, a single
|
||||
global object `acorn` will be defined, and all the exported properties
|
||||
will be added to that.
|
||||
|
||||
### Main parser
|
||||
|
||||
This is implemented in `dist/acorn.js`, and is what you get when you
|
||||
`require("acorn")` in node.js.
|
||||
|
||||
**parse**`(input, options)` is used to parse a JavaScript program.
|
||||
The `input` parameter is a string, `options` can be undefined or an
|
||||
object setting some of the options listed below. The return value will
|
||||
be an abstract syntax tree object as specified by the
|
||||
[ESTree spec][estree].
|
||||
|
||||
When encountering a syntax error, the parser will raise a
|
||||
`SyntaxError` object with a meaningful message. The error object will
|
||||
have a `pos` property that indicates the character offset at which the
|
||||
error occurred, and a `loc` object that contains a `{line, column}`
|
||||
object referring to that same position.
|
||||
|
||||
[estree]: https://github.com/estree/estree
|
||||
|
||||
- **ecmaVersion**: Indicates the ECMAScript version to parse. Must be
|
||||
either 3, 5, or 6. This influences support for strict mode, the set
|
||||
of reserved words, and support for new syntax features. Default is 5.
|
||||
|
||||
- **sourceType**: Indicate the mode the code should be parsed in. Can be
|
||||
either `"script"` or `"module"`.
|
||||
|
||||
- **onInsertedSemicolon**: If given a callback, that callback will be
|
||||
called whenever a missing semicolon is inserted by the parser. The
|
||||
callback will be given the character offset of the point where the
|
||||
semicolon is inserted as argument, and if `locations` is on, also a
|
||||
`{line, column}` object representing this position.
|
||||
|
||||
- **onTrailingComma**: Like `onInsertedSemicolon`, but for trailing
|
||||
commas.
|
||||
|
||||
- **allowReserved**: If `false`, using a reserved word will generate
|
||||
an error. Defaults to `true`. When given the value `"never"`,
|
||||
reserved words and keywords can also not be used as property names
|
||||
(as in Internet Explorer's old parser).
|
||||
|
||||
- **allowReturnOutsideFunction**: By default, a return statement at
|
||||
the top level raises an error. Set this to `true` to accept such
|
||||
code.
|
||||
|
||||
- **allowImportExportEverywhere**: By default, `import` and `export`
|
||||
declarations can only appear at a program's top level. Setting this
|
||||
option to `true` allows them anywhere where a statement is allowed.
|
||||
|
||||
- **allowHashBang**: When this is enabled (off by default), if the
|
||||
code starts with the characters `#!` (as in a shellscript), the
|
||||
first line will be treated as a comment.
|
||||
|
||||
- **locations**: When `true`, each node has a `loc` object attached
|
||||
with `start` and `end` subobjects, each of which contains the
|
||||
one-based line and zero-based column numbers in `{line, column}`
|
||||
form. Default is `false`.
|
||||
|
||||
- **onToken**: If a function is passed for this option, each found
|
||||
token will be passed in same format as `tokenize()` returns.
|
||||
|
||||
If array is passed, each found token is pushed to it.
|
||||
|
||||
Note that you are not allowed to call the parser from the
|
||||
callback—that will corrupt its internal state.
|
||||
|
||||
- **onComment**: If a function is passed for this option, whenever a
|
||||
comment is encountered the function will be called with the
|
||||
following parameters:
|
||||
|
||||
- `block`: `true` if the comment is a block comment, false if it
|
||||
is a line comment.
|
||||
- `text`: The content of the comment.
|
||||
- `start`: Character offset of the start of the comment.
|
||||
- `end`: Character offset of the end of the comment.
|
||||
|
||||
When the `locations` options is on, the `{line, column}` locations
|
||||
of the comment’s start and end are passed as two additional
|
||||
parameters.
|
||||
|
||||
If array is passed for this option, each found comment is pushed
|
||||
to it as object in Esprima format:
|
||||
|
||||
```javascript
|
||||
{
|
||||
"type": "Line" | "Block",
|
||||
"value": "comment text",
|
||||
"range": ...,
|
||||
"loc": ...
|
||||
}
|
||||
```
|
||||
|
||||
Note that you are not allowed to call the parser from the
|
||||
callback—that will corrupt its internal state.
|
||||
|
||||
- **ranges**: Nodes have their start and end characters offsets
|
||||
recorded in `start` and `end` properties (directly on the node,
|
||||
rather than the `loc` object, which holds line/column data. To also
|
||||
add a [semi-standardized][range] `range` property holding a
|
||||
`[start, end]` array with the same numbers, set the `ranges` option
|
||||
to `true`.
|
||||
|
||||
- **program**: It is possible to parse multiple files into a single
|
||||
AST by passing the tree produced by parsing the first file as the
|
||||
`program` option in subsequent parses. This will add the toplevel
|
||||
forms of the parsed file to the "Program" (top) node of an existing
|
||||
parse tree.
|
||||
|
||||
- **sourceFile**: When the `locations` option is `true`, you can pass
|
||||
this option to add a `source` attribute in every node’s `loc`
|
||||
object. Note that the contents of this option are not examined or
|
||||
processed in any way; you are free to use whatever format you
|
||||
choose.
|
||||
|
||||
- **directSourceFile**: Like `sourceFile`, but a `sourceFile` property
|
||||
will be added directly to the nodes, rather than the `loc` object.
|
||||
|
||||
- **preserveParens**: If this option is `true`, parenthesized expressions
|
||||
are represented by (non-standard) `ParenthesizedExpression` nodes
|
||||
that have a single `expression` property containing the expression
|
||||
inside parentheses.
|
||||
|
||||
[range]: https://bugzilla.mozilla.org/show_bug.cgi?id=745678
|
||||
|
||||
**parseExpressionAt**`(input, offset, options)` will parse a single
|
||||
expression in a string, and return its AST. It will not complain if
|
||||
there is more of the string left after the expression.
|
||||
|
||||
**getLineInfo**`(input, offset)` can be used to get a `{line,
|
||||
column}` object for a given program string and character offset.
|
||||
|
||||
**tokenizer**`(input, options)` returns an object with a `getToken`
|
||||
method that can be called repeatedly to get the next token, a `{start,
|
||||
end, type, value}` object (with added `loc` property when the
|
||||
`locations` option is enabled and `range` property when the `ranges`
|
||||
option is enabled). When the token's type is `tokTypes.eof`, you
|
||||
should stop calling the method, since it will keep returning that same
|
||||
token forever.
|
||||
|
||||
In ES6 environment, returned result can be used as any other
|
||||
protocol-compliant iterable:
|
||||
|
||||
```javascript
|
||||
for (let token of acorn.tokenize(str)) {
|
||||
// iterate over the tokens
|
||||
}
|
||||
|
||||
// transform code to array of tokens:
|
||||
var tokens = [...acorn.tokenize(str)];
|
||||
```
|
||||
|
||||
**tokTypes** holds an object mapping names to the token type objects
|
||||
that end up in the `type` properties of tokens.
|
||||
|
||||
#### Note on using with [Escodegen][escodegen]
|
||||
|
||||
Escodegen supports generating comments from AST, attached in
|
||||
Esprima-specific format. In order to simulate same format in
|
||||
Acorn, consider following example:
|
||||
|
||||
```javascript
|
||||
var comments = [], tokens = [];
|
||||
|
||||
var ast = acorn.parse('var x = 42; // answer', {
|
||||
// collect ranges for each node
|
||||
ranges: true,
|
||||
// collect comments in Esprima's format
|
||||
onComment: comments,
|
||||
// collect token ranges
|
||||
onToken: tokens
|
||||
});
|
||||
|
||||
// attach comments using collected information
|
||||
escodegen.attachComments(ast, comments, tokens);
|
||||
|
||||
// generate code
|
||||
console.log(escodegen.generate(ast, {comment: true}));
|
||||
// > 'var x = 42; // answer'
|
||||
```
|
||||
|
||||

|
||||
|
||||
#### Using Acorn in an environment with a Content Security Policy
|
||||
|
||||
Some contexts, such as Chrome Web Apps, disallow run-time code evaluation.
|
||||
Acorn uses `new Function` to generate fast functions that test whether
|
||||
a word is in a given set, and will trigger a security error when used
|
||||
in a context with such a
|
||||
[Content Security Policy](http://www.html5rocks.com/en/tutorials/security/content-security-policy/#eval-too)
|
||||
(see [#90](https://github.com/marijnh/acorn/issues/90) and
|
||||
[#123](https://github.com/marijnh/acorn/issues/123)).
|
||||
|
||||
The `dist/acorn_csp.js` file in the distribution (which is built
|
||||
by the `bin/without_eval` script) has the generated code inlined, and
|
||||
can thus run without evaluating anything.
|
||||
|
||||
### dist/acorn_loose.js ###
|
||||
|
||||
This file implements an error-tolerant parser. It exposes a single
|
||||
function. The loose parser is accessible in node.js via `require("acorn/dist/acorn_loose")`.
|
||||
|
||||
**parse_dammit**`(input, options)` takes the same arguments and
|
||||
returns the same syntax tree as the `parse` function in `acorn.js`,
|
||||
but never raises an error, and will do its best to parse syntactically
|
||||
invalid code in as meaningful a way as it can. It'll insert identifier
|
||||
nodes with name `"✖"` as placeholders in places where it can't make
|
||||
sense of the input. Depends on `acorn.js`, because it uses the same
|
||||
tokenizer.
|
||||
|
||||
### dist/walk.js ###
|
||||
|
||||
Implements an abstract syntax tree walker. Will store its interface in
|
||||
`acorn.walk` when loaded without a module system.
|
||||
|
||||
**simple**`(node, visitors, base, state)` does a 'simple' walk over
|
||||
a tree. `node` should be the AST node to walk, and `visitors` an
|
||||
object with properties whose names correspond to node types in the
|
||||
[ESTree spec][estree]. The properties should contain functions
|
||||
that will be called with the node object and, if applicable the state
|
||||
at that point. The last two arguments are optional. `base` is a walker
|
||||
algorithm, and `state` is a start state. The default walker will
|
||||
simply visit all statements and expressions and not produce a
|
||||
meaningful state. (An example of a use of state it to track scope at
|
||||
each point in the tree.)
|
||||
|
||||
**ancestor**`(node, visitors, base, state)` does a 'simple' walk over
|
||||
a tree, building up an array of ancestor nodes (including the current node)
|
||||
and passing the array to callbacks in the `state` parameter.
|
||||
|
||||
**recursive**`(node, state, functions, base)` does a 'recursive'
|
||||
walk, where the walker functions are responsible for continuing the
|
||||
walk on the child nodes of their target node. `state` is the start
|
||||
state, and `functions` should contain an object that maps node types
|
||||
to walker functions. Such functions are called with `(node, state, c)`
|
||||
arguments, and can cause the walk to continue on a sub-node by calling
|
||||
the `c` argument on it with `(node, state)` arguments. The optional
|
||||
`base` argument provides the fallback walker functions for node types
|
||||
that aren't handled in the `functions` object. If not given, the
|
||||
default walkers will be used.
|
||||
|
||||
**make**`(functions, base)` builds a new walker object by using the
|
||||
walker functions in `functions` and filling in the missing ones by
|
||||
taking defaults from `base`.
|
||||
|
||||
**findNodeAt**`(node, start, end, test, base, state)` tries to
|
||||
locate a node in a tree at the given start and/or end offsets, which
|
||||
satisfies the predicate `test`. `start` end `end` can be either `null`
|
||||
(as wildcard) or a number. `test` may be a string (indicating a node
|
||||
type) or a function that takes `(nodeType, node)` arguments and
|
||||
returns a boolean indicating whether this node is interesting. `base`
|
||||
and `state` are optional, and can be used to specify a custom walker.
|
||||
Nodes are tested from inner to outer, so if two nodes match the
|
||||
boundaries, the inner one will be preferred.
|
||||
|
||||
**findNodeAround**`(node, pos, test, base, state)` is a lot like
|
||||
`findNodeAt`, but will match any node that exists 'around' (spanning)
|
||||
the given position.
|
||||
|
||||
**findNodeAfter**`(node, pos, test, base, state)` is similar to
|
||||
`findNodeAround`, but will match all nodes *after* the given position
|
||||
(testing outer nodes before inner nodes).
|
||||
|
||||
## Command line interface
|
||||
|
||||
The `bin/acorn` utility can be used to parse a file from the command
|
||||
line. It accepts as arguments its input file and the following
|
||||
options:
|
||||
|
||||
- `--ecma3|--ecma5|--ecma6`: Sets the ECMAScript version to parse. Default is
|
||||
version 5.
|
||||
|
||||
- `--locations`: Attaches a "loc" object to each node with "start" and
|
||||
"end" subobjects, each of which contains the one-based line and
|
||||
zero-based column numbers in `{line, column}` form.
|
||||
|
||||
- `--allow-hash-bang`: If the code starts with the characters #! (as in a shellscript), the first line will be treated as a comment.
|
||||
|
||||
- `--compact`: No whitespace is used in the AST output.
|
||||
|
||||
- `--silent`: Do not output the AST, just return the exit status.
|
||||
|
||||
- `--help`: Print the usage information and quit.
|
||||
|
||||
The utility spits out the syntax tree as JSON data.
|
||||
|
||||
## Build system
|
||||
|
||||
Acorn is written in ECMAScript 6, as a set of small modules, in the
|
||||
project's `src` directory, and compiled down to bigger ECMAScript 3
|
||||
files in `dist` using [Browserify](http://browserify.org) and
|
||||
[Babel](http://babeljs.io/). If you are already using Babel, you can
|
||||
consider including the modules directly.
|
||||
|
||||
The command-line test runner (`npm test`) uses the ES6 modules. The
|
||||
browser-based test page (`test/index.html`) uses the compiled modules.
|
||||
The `bin/build-acorn.js` script builds the latter from the former.
|
||||
|
||||
If you are working on Acorn, you'll probably want to try the code out
|
||||
directly, without an intermediate build step. In your scripts, you can
|
||||
register the Babel require shim like this:
|
||||
|
||||
require("babel-core/register")
|
||||
|
||||
That will allow you to directly `require` the ES6 modules.
|
||||
|
||||
## Plugins
|
||||
|
||||
Acorn is designed support allow plugins which, within reasonable
|
||||
bounds, redefine the way the parser works. Plugins can add new token
|
||||
types and new tokenizer contexts (if necessary), and extend methods in
|
||||
the parser object. This is not a clean, elegant API—using it requires
|
||||
an understanding of Acorn's internals, and plugins are likely to break
|
||||
whenever those internals are significantly changed. But still, it is
|
||||
_possible_, in this way, to create parsers for JavaScript dialects
|
||||
without forking all of Acorn. And in principle it is even possible to
|
||||
combine such plugins, so that if you have, for example, a plugin for
|
||||
parsing types and a plugin for parsing JSX-style XML literals, you
|
||||
could load them both and parse code with both JSX tags and types.
|
||||
|
||||
A plugin should register itself by adding a property to
|
||||
`acorn.plugins`, which holds a function. Calling `acorn.parse`, a
|
||||
`plugins` option can be passed, holding an object mapping plugin names
|
||||
to configuration values (or just `true` for plugins that don't take
|
||||
options). After the parser object has been created, the initialization
|
||||
functions for the chosen plugins are called with `(parser,
|
||||
configValue)` arguments. They are expected to use the `parser.extend`
|
||||
method to extend parser methods. For example, the `readToken` method
|
||||
could be extended like this:
|
||||
|
||||
```javascript
|
||||
parser.extend("readToken", function(nextMethod) {
|
||||
return function(code) {
|
||||
console.log("Reading a token!")
|
||||
return nextMethod.call(this, code)
|
||||
}
|
||||
})
|
||||
```
|
||||
|
||||
The `nextMethod` argument passed to `extend`'s second argument is the
|
||||
previous value of this method, and should usually be called through to
|
||||
whenever the extended method does not handle the call itself.
|
||||
|
||||
There is a proof-of-concept JSX plugin in the [`jsx`
|
||||
branch](https://github.com/marijnh/acorn/tree/jsx) branch of the
|
||||
Github repository.

// Acorn: Loose parser
|
||||
//
|
||||
// This module provides an alternative parser (`parse_dammit`) that
|
||||
// exposes that same interface as `parse`, but will try to parse
|
||||
// anything as JavaScript, repairing syntax error the best it can.
|
||||
// There are circumstances in which it will raise an error and give
|
||||
// up, but they are very rare. The resulting AST will be a mostly
|
||||
// valid JavaScript AST (as per the [Mozilla parser API][api], except
|
||||
// that:
|
||||
//
|
||||
// - Return outside functions is allowed
|
||||
//
|
||||
// - Label consistency (no conflicts, break only to existing labels)
|
||||
// is not enforced.
|
||||
//
|
||||
// - Bogus Identifier nodes with a name of `"✖"` are inserted whenever
|
||||
// the parser got too confused to return anything meaningful.
|
||||
//
|
||||
// [api]: https://developer.mozilla.org/en-US/docs/SpiderMonkey/Parser_API
|
||||
//
|
||||
// The expected use for this is to *first* try `acorn.parse`, and only
|
||||
// if that fails switch to `parse_dammit`. The loose parser might
|
||||
// parse badly indented code incorrectly, so **don't** use it as
|
||||
// your default parser.
|
||||
//
|
||||
// Quite a lot of acorn.js is duplicated here. The alternative was to
|
||||
// add a *lot* of extra cruft to that file, making it less readable
|
||||
// and slower. Copying and editing the code allowed me to make
|
||||
// invasive changes and simplifications without creating a complicated
|
||||
// tangle.
