The default value of the `ecmaVersion` option is now 6 (used to be 5).
|
||||
|
||||
Support for comprehension syntax (which was dropped from the draft spec) has been removed.
|
||||
|
||||
### Fixes
|
||||
|
||||
`let` and `yield` are now “contextual keywords”, meaning you can mostly use them as identifiers in ES5 non-strict code.
|
||||
|
||||
A parenthesized class or function expression after `export default` is now parsed correctly.
|
||||
|
||||
### New features
|
||||
|
||||
When `ecmaVersion` is set to 7, Acorn will parse the exponentiation operator (`**`).
|
||||
|
||||
The identifier character ranges are now based on Unicode 8.0.0.
|
||||
|
||||
Plugins can now override the `raiseRecoverable` method to override the way non-critical errors are handled.
|
||||
|
||||
## 2.7.0 (2016-01-04)
|
||||
|
||||
### Fixes
|
||||
|
||||
Stop allowing rest parameters in setters.
|
||||
|
||||
Disallow `y` rexexp flag in ES5.
|
||||
|
||||
Disallow `\00` and `\000` escapes in strict mode.
|
||||
|
||||
Raise an error when an import name is a reserved word.
|
||||
|
||||
## 2.6.2 (2015-11-10)
|
||||
|
||||
### Fixes
|
||||
|
||||
Don't crash when no options object is passed.
|
||||
|
||||
## 2.6.0 (2015-11-09)
|
||||
|
||||
### Fixes
|
||||
|
||||
Add `await` as a reserved word in module sources.
|
||||
|
||||
Disallow `yield` in a parameter default value for a generator.
|
||||
|
||||
Forbid using a comma after a rest pattern in an array destructuring.
|
||||
|
||||
### New features
|
||||
|
||||
Support parsing stdin in command-line tool.
|
||||
|
||||
## 2.5.0 (2015-10-27)
|
||||
|
||||
### Fixes
|
||||
|
||||
Fix tokenizer support in the command-line tool.
|
||||
|
||||
Stop allowing `new.target` outside of functions.
|
||||
|
||||
Remove legacy `guard` and `guardedHandler` properties from try nodes.
|
||||
|
||||
Stop allowing multiple `__proto__` properties on an object literal in strict mode.
|
||||
|
||||
Don't allow rest parameters to be non-identifier patterns.
|
||||
|
||||
Check for duplicate paramter names in arrow functions.

# Acorn
|
||||
|
||||
A tiny, fast JavaScript parser written in JavaScript.
|
||||
|
||||
## Community
|
||||
|
||||
Acorn is open source software released under an
|
||||
[MIT license](https://github.com/acornjs/acorn/blob/master/acorn/LICENSE).
|
||||
|
||||
You are welcome to
|
||||
[report bugs](https://github.com/acornjs/acorn/issues) or create pull
|
||||
requests on [github](https://github.com/acornjs/acorn). For questions
|
||||
and discussion, please use the
|
||||
[Tern discussion forum](https://discuss.ternjs.net).
|
||||
|
||||
## Installation
|
||||
|
||||
The easiest way to install acorn is from [`npm`](https://www.npmjs.com/):
|
||||
|
||||
```sh
|
||||
npm install acorn
|
||||
```
|
||||
|
||||
Alternately, you can download the source and build acorn yourself:
|
||||
|
||||
```sh
|
||||
git clone https://github.com/acornjs/acorn.git
|
||||
cd acorn
|
||||
npm install
|
||||
```
|
||||
|
||||
## Interface
|
||||
|
||||
**parse**`(input, options)` is the main interface to the library. 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](https://github.com/estree/estree).
|
||||
|
||||
```javascript
|
||||
let acorn = require("acorn");
|
||||
console.log(acorn.parse("1 + 1"));
|
||||
```
|
||||
|
||||
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 string offset at which the
|
||||
error occurred, and a `loc` object that contains a `{line, column}`
|
||||
object referring to that same position.
|
||||
|
||||
Options can be provided by passing a second argument, which should be
|
||||
an object containing any of these fields:
|
||||
|
||||
- **ecmaVersion**: Indicates the ECMAScript version to parse. Must be
|
||||
either 3, 5, 6 (2015), 7 (2016), 8 (2017), 9 (2018), 10 (2019) or 11
|
||||
(2020, partial support). This influences support for strict mode,
|
||||
the set of reserved words, and support for new syntax features.
|
||||
Default is 10.
|
||||
|
||||
**NOTE**: Only 'stage 4' (finalized) ECMAScript features are being
|
||||
implemented by Acorn. Other proposed new features can be implemented
|
||||
through plugins.
|
||||
|
||||
- **sourceType**: Indicate the mode the code should be parsed in. Can be
|
||||
either `"script"` or `"module"`. This influences global strict mode
|
||||
and parsing of `import` and `export` declarations.
|
||||
|
||||
**NOTE**: If set to `"module"`, then static `import` / `export` syntax
|
||||
will be valid, even if `ecmaVersion` is less than 6.
|
||||
|
||||
- **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` for `ecmaVersion` 3, `false` for higher
|
||||
versions. 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.
|
||||
|
||||
- **allowAwaitOutsideFunction**: By default, `await` expressions can
|
||||
only appear inside `async` functions. Setting this option to
|
||||
`true` allows to have top-level `await` expressions. They are
|
||||
still not allowed in non-`async` functions, though.
|
||||
|
||||
- **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 tokens returned from
|
||||
`tokenizer().getToken()`.
|
||||
|
||||
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",
|
||||
"start": Number,
|
||||
"end": Number,
|
||||
// If `locations` option is on:
|
||||
"loc": {
|
||||
"start": {line: Number, column: Number}
|
||||
"end": {line: Number, column: Number}
|
||||
},
|
||||
// If `ranges` option is on:
|
||||
"range": [Number, Number]
|
||||
}
|
||||
```
|
||||
|
||||
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](https://bugzilla.mozilla.org/show_bug.cgi?id=745678)
|
||||
`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 (regardless of the `location` option) 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.
|
||||
|
||||
**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.
|
||||
|
||||
**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.tokenizer(str)) {
|
||||
// iterate over the tokens
|
||||
}
|
||||
|
||||
// transform code to array of tokens:
|
||||
var tokens = [...acorn.tokenizer(str)];
|
||||
```
|
||||
|
||||
**tokTypes** holds an object mapping names to the token type objects
|
||||
that end up in the `type` properties of tokens.
|
||||
|
||||
**getLineInfo**`(input, offset)` can be used to get a `{line,
|
||||
column}` object for a given program string and offset.
|
||||
|
||||
### The `Parser` class
|
||||
|
||||
Instances of the **`Parser`** class contain all the state and logic
|
||||
that drives a parse. It has static methods `parse`,
|
||||
`parseExpressionAt`, and `tokenizer` that match the top-level
|
||||
functions by the same name.
|
||||
|
||||
When extending the parser with plugins, you need to call these methods
|
||||
on the extended version of the class. To extend a parser with plugins,
|
||||
you can use its static `extend` method.
|
||||
|
||||
```javascript
|
||||
var acorn = require("acorn");
|
||||
var jsx = require("acorn-jsx");
|
||||
var JSXParser = acorn.Parser.extend(jsx());
|
||||
JSXParser.parse("foo(<bar/>)");
|
||||
```
|
||||
|
||||
The `extend` method takes any number of plugin values, and returns a
|
||||
new `Parser` class that includes the extra parser logic provided by
|
||||
the plugins.
|
||||
|
||||
## 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|--ecma7|--ecma8|--ecma9|--ecma10`: Sets the ECMAScript version
|
||||
to parse. Default is version 9.
|
||||
|
||||
- `--module`: Sets the parsing mode to `"module"`. Is set to `"script"` otherwise.
|
||||
|
||||
- `--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.
