# Dynamic import support in acorn
|
||||||
|
|
||||||
|
This is plugin for [Acorn](http://marijnhaverbeke.nl/acorn/) - a tiny, fast JavaScript parser, written completely in JavaScript.
|
||||||
|
|
||||||
|
For more information, check out the [proposal repo](https://github.com/tc39/proposal-dynamic-import).
|
||||||
|
|
||||||
|
## Usage
|
||||||
|
|
||||||
|
You can use this module directly in order to get Acorn instance with plugin installed:
|
||||||
|
|
||||||
|
```js
|
||||||
|
import acorn from 'acorn-dynamic-import';
|
||||||
|
// or...
|
||||||
|
const acorn = require('acorn-dynamic-import').default;
|
||||||
|
```
|
||||||
|
|
||||||
|
Or you can use `inject.js` for injecting plugin into your own version of Acorn like this:
|
||||||
|
|
||||||
|
```js
|
||||||
|
const acorn = require('acorn-dynamic-import/lib/inject').default(require('./custom-acorn'));
|
||||||
|
```
|
||||||
|
|
||||||
|
Then, use the `plugins` option whenever you need to support dynamicImport while parsing:
|
||||||
|
|
||||||
|
```js
|
||||||
|
const ast = acorn.parse(code, {
|
||||||
|
plugins: { dynamicImport: true }
|
||||||
|
});
|
||||||
|
```
|
||||||
|
|
||||||
|

|
||||||
|
## 4.0.11 (2017-02-07)
|
||||||
|
|
||||||
|
### Bug fixes
|
||||||
|
|
||||||
|
Allow all forms of member expressions to be parenthesized as lvalue.
|
||||||
|
|
||||||
|
## 4.0.10 (2017-02-07)
|
||||||
|
|
||||||
|
### Bug fixes
|
||||||
|
|
||||||
|
Don't expect semicolons after default-exported functions or classes,
|
||||||
|
even when they are expressions.
|
||||||
|
|
||||||
|
Check for use of `'use strict'` directives in non-simple parameter
|
||||||
|
functions, even when already in strict mode.
|
||||||
|
|
||||||
|
## 4.0.9 (2017-02-06)
|
||||||
|
|
||||||
|
### Bug fixes
|
||||||
|
|
||||||
|
Fix incorrect error raised for parenthesized simple assignment
|
||||||
|
targets, so that `(x) = 1` parses again.
|
||||||
|
|
||||||
|
## 4.0.8 (2017-02-03)
|
||||||
|
|
||||||
|
### Bug fixes
|
||||||
|
|
||||||
|
Solve spurious parenthesized pattern errors by temporarily erring on
|
||||||
|
the side of accepting programs that our delayed errors don't handle
|
||||||
|
correctly yet.
|
||||||
|
|
||||||
|
## 4.0.7 (2017-02-02)
|
||||||
|
|
||||||
|
### Bug fixes
|
||||||
|
|
||||||
|
Accept invalidly rejected code like `(x).y = 2` again.
|
||||||
|
|
||||||
|
Don't raise an error when a function _inside_ strict code has a
|
||||||
|
non-simple parameter list.
|
||||||
|
|
||||||
|
## 4.0.6 (2017-02-02)
|
||||||
|
|
||||||
|
### Bug fixes
|
||||||
|
|
||||||
|
Fix exponential behavior (manifesting itself as a complete hang for
|
||||||
|
even relatively small source files) introduced by the new 'use strict'
|
||||||
|
check.
|
||||||
|
|
||||||
|
## 4.0.5 (2017-02-02)
|
||||||
|
|
||||||
|
### Bug fixes
|
||||||
|
|
||||||
|
Disallow parenthesized pattern expressions.
|
||||||
|
|
||||||
|
Allow keywords as export names.
|
||||||
|
|
||||||
|
Don't allow the `async` keyword to be parenthesized.
|
||||||
|
|
||||||
|
Properly raise an error when a keyword contains a character escape.
|
||||||
|
|
||||||
|
Allow `"use strict"` to appear after other string literal expressions.
|
||||||
|
|
||||||
|
Disallow labeled declarations.
|
||||||
|
|
||||||
|
## 4.0.4 (2016-12-19)
|
||||||
|
|
||||||
|
### Bug fixes
|
||||||
|
|
||||||
|
Fix issue with loading acorn_loose.js with an AMD loader.
|
||||||
|
|
||||||
|
Fix crash when `export` was followed by a keyword that can't be
|
||||||
|
exported.
|
||||||
|
|
||||||
|
## 4.0.3 (2016-08-16)
|
||||||
|
|
||||||
|
### Bug fixes
|
||||||
|
|
||||||
|
Allow regular function declarations inside single-statement `if`
|
||||||
|
branches in loose mode. Forbid them entirely in strict mode.
|
||||||
|
|
||||||
|
Properly parse properties named `async` in ES2017 mode.
|
||||||
|
|

|
### New features
|
||||||
|
|
||||||
|
Visitors created with `visit.make` now have their base as _prototype_,
|
||||||
|
rather than copying properties into a fresh object.
|
||||||
|
|
||||||
|
Make it possible to use `visit.ancestor` with a walk state.
|
||||||
|
|
||||||
|
## 3.1.0 (2016-04-18)
|
||||||
|
|

|
||||||
|
|
||||||
|
## 3.0.0 (2016-02-10)
|
||||||
|
|
||||||
|
### Breaking changes
|
||||||
|
|
||||||
|
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.
|
||||||
|
|
||||||
|
Make sure the loose parser always attaches a `local` property to
|
||||||
|
`ImportNamespaceSpecifier` nodes.
|
||||||
|
|
||||||
|
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.
|
||||||
|
|
||||||
|

||||||
|
|
||||||

||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
Disallow `yield` in a parameter default value for a generator.
|
||||||
|
|
||||||
|
Forbid using a comma after a rest pattern in an array destructuring.

||||||
|
|
||||||
|
Support parsing stdin in command-line tool.
|
||||||
|
|
||||||
|
## 2.5.2 (2015-10-27)
|
||||||
|
|
||||||
|
### Fixes
|
||||||
|
|
||||||
|
Fix bug where the walker walked an exported `let` statement as an
|
||||||
|
expression.
|
||||||
|
|
||||||
|
## 2.5.0 (2015-10-27)
|
||||||
|
|
||||||
|
### Fixes
|
||||||
|
|
||||||
|

|
||||||
|
sources.
|
||||||
|
|
||||||
|
Stop allowing `new.target` outside of functions.
|
||||||
|
|
||||||
|
Remove legacy `guard` and `guardedHandler` properties from try nodes.
|
||||||

|
||||||
|
strict mode.
|

|
A tiny, fast JavaScript parser, written completely in JavaScript.
|
||||||
|
|
||||||
|
## Community
|
||||||
|
|
||||||
|
Acorn is open source software released under an
|
||||||
|
[MIT license](https://github.com/ternjs/acorn/blob/master/LICENSE).
|
||||||
|
|
||||||
|
You are welcome to
|
||||||
|
[report bugs](https://github.com/ternjs/acorn/issues) or create pull
|
||||||
|
requests on [github](https://github.com/ternjs/acorn). For questions
|
||||||
|
and discussion, please use the
|
||||||
|
[Tern discussion forum](https://discuss.ternjs.net).
|
||||||
|
|
||||||
|
## Installation
|
||||||
|
|
||||||
|
The easiest way to install acorn is with [`npm`][npm].
|
||||||
|
|
||||||
|
[npm]: https://www.npmjs.com/
|
||||||
|
|
||||||
|
```sh
|
||||||
|
npm install acorn
|
||||||
|
```
|
||||||
|
|
||||||
|
Alternately, download the source.
|
||||||
|
|
||||||
|
```sh
|
||||||
|
git clone https://github.com/ternjs/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, 6 (2015), 7 (2016), or 8 (2017). This influences support for strict
|
||||||
|
mode, the set of reserved words, and support for new syntax features.
|
||||||
|
Default is 7.
|
||||||
|
|
||||||
|
**NOTE**: Only 'stage 4' (finalized) ECMAScript features are being
|
||||||
|
implemented by Acorn.
|
||||||
|
|
||||||
|
- **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.
|
||||||
|
|
||||||
|
- **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.
|
||||||
|
|
||||||
|
- **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][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 (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.
|
||||||
|
|
||||||
|
[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.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.
|
||||||
|
|
||||||
|
#### 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'
|
||||||
|
```

### 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 is 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 the callbacks as a third 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` and `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|--ecma7`: Sets the ECMAScript version to parse. Default is
|
||||||
|
version 5.
|
||||||
|
|
||||||
|
- `--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.
|
||||||
|
|
||||||
|
## 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.
|
||||||
|
|
||||||
|
Similarly, the loose parser allows plugins to register themselves via
|
||||||
|
`acorn.pluginsLoose`. The extension mechanism is the same as for the
|
||||||
|
normal parser:
|
||||||
|
|
||||||
|
```javascript
|
||||||
|
looseParser.extend("readToken", function(nextMethod) {
|
||||||
|
return function() {
|
||||||
|
console.log("Reading a token in the loose parser!")
|
||||||
|
return nextMethod.call(this)
|
||||||
|
}
|
||||||
|
})
|
||||||
|
```
|
||||||
|
|
||||||
|

// A recursive descent parser operates by defining functions for all

// syntactic elements, and recursively calling those, each function
|
||||||
|
// advancing the input stream and returning an AST node. Precedence
|
||||||
|
// of constructs (for example, the fact that `!x[1]` means `!(x[1])`
|
||||||
|
// instead of `(!x)[1]` is handled by the fact that the parser
|
||||||
|
// function that parses unary prefix operators is called first, and
|
||||||
|
// in turn calls the function that parses `[]` subscripts — that
|
||||||
|
// way, it'll receive the node for `x[1]` already parsed, and wraps
|
||||||
|
// *that* in the unary operator node.
|
||||||
|
//
|
||||||
|
// Acorn uses an [operator precedence parser][opp] to handle binary
|
||||||
|
// operator precedence, because it is much more compact than using
|
||||||
|
// the technique outlined above, which uses different, nesting
|

// functions to specify precedence, for all of the ten binary

// 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.

targets, so that `(x) = 1` parses again.
|
||||||
|
|
||||||
|
## 4.0.8 (2017-02-03)
|
||||||
|
|
||||||
|
### Bug fixes
|
||||||
|

||||||
|
even relatively small source files) introduced by the new 'use strict'
|
||||||
|
check.
|
||||||
|
|
||||||
|
## 4.0.5 (2017-02-02)

||||||
|
|
||||||
|
### Bug fixes
|
||||||
|
|
||||||
|
The parser now raises errors on duplicated export names.
|
||||||
|
|
||||||
|
`arguments` and `eval` can now be used in shorthand properties.
|
||||||
|
|
||||||
|

|
||||||
|
rather than copying properties into a fresh object.
|
||||||
|
|
||||||
|
Make it possible to use `visit.ancestor` with a walk state.
|
||||||
|
|
||||||
|
## 3.1.0 (2016-04-18)
|
||||||
|
|

|
||||||
|
|
||||||
|
### Breaking changes

|
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.
|
||||||
|
|

||||||
|
### New features
|
||||||
|
|
||||||
|
When `ecmaVersion` is set to 7, Acorn will parse the exponentiation
|
||||||

||||||
|
|
||||||
|
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.
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
### Fixes
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
Make sure the loose parser always attaches a `local` property to
|
||||||
|
`ImportNamespaceSpecifier` nodes.
|
||||||
|
|
||||||
|
Disallow `y` rexexp flag in ES5.
|
||||||

||||||
|
|

|
||||||
|

A tiny, fast JavaScript parser, written completely in JavaScript.
|
||||||
|
|
||||||
|
## Community
|
||||||
|
|
||||||
|
Acorn is open source software released under an
|
||||||
|
[MIT license](https://github.com/acornjs/acorn/blob/master/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 with [`npm`][npm].
|
||||||
|
|
||||||
|
[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
|
||||||
|
npm run build
|
||||||
|
```
|
||||||
|
|
||||||
|
## 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, 6 (2015), 7 (2016), 8 (2017), 9 (2018) or 10 (2019, partial
|
||||||
|
support). This influences support for strict mode, the set of
|
||||||
|
reserved words, and support for new syntax features. Default is 7.
|
||||||
|
|
||||||
|
**NOTE**: Only 'stage 4' (finalized) ECMAScript features are being
|
||||||
|
implemented by Acorn.
|
||||||
|
|
||||||
|
- **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.
|
||||||
|
|
||||||
|
- **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][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 (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.
|
||||||
|
|
||||||
|
[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.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.
|
||||||
|
|
||||||
|
#### 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'
|
||||||
|
```

### 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 is to track scope at
|
||||||
|
each point in the tree.)
|
||||||
|
|
||||||
|
```js
|
||||||
|
const acorn = require("acorn")
|
||||||
|
const walk = require("acorn/dist/walk")
|
||||||
|
|
||||||
|
walk.simple(acorn.parse("let x = 10"), {
|
||||||
|
Literal(node) {
|
||||||
|
console.log(`Found a literal: ${node.value}`)
|
||||||
|
}
|
||||||
|
})
|
||||||
|
```
|
||||||
|
|
||||||
|
**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 the callbacks as a third parameter.
|
||||||
|
|
||||||
|
```js
|
||||||
|
const acorn = require("acorn")
|
||||||
|
const walk = require("acorn/dist/walk")
|
||||||
|
|
||||||
|
walk.ancestor(acorn.parse("foo('hi')"), {
|
||||||
|
Literal(_, ancestors) {
|
||||||
|
console.log("This literal's ancestors are:",
|
||||||
|
ancestors.map(n => n.type))
|
||||||
|
}
|
||||||
|
})
|
||||||
|
```
|
||||||
|
|
||||||
|
**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`.
|
||||||
|
|
||||||
|
**full**`(node, callback, base, state)` does a 'full'
|
||||||
|
walk over a tree, calling the callback with the arguments (node, state, type)
|
||||||
|
for each node
|
||||||
|
|
||||||
|
**fullAncestor**`(node, callback, base, state)` does a 'full' walk over
|
||||||
|
a tree, building up an array of ancestor nodes (including the current node)
|
||||||
|
and passing the array to the callbacks as a third parameter.
|
||||||
|
|
||||||
|
```js
|
||||||
|
const acorn = require("acorn")
|
||||||
|
const walk = require("acorn/dist/walk")
|
||||||
|
|
||||||
|
walk.full(acorn.parse("1 + 1"), node => {
|
||||||
|
console.log(`There's a ${node.type} node at ${node.ch}`)
|
||||||
|
})
|
||||||
|
```
|
||||||
|
|
||||||
|
**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` and `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|--ecma7|--ecma8|--ecma9|--ecma10`: Sets the ECMAScript version
|
||||||
|
to parse. Default is version 7.
|
||||||
|
|
||||||
|
- `--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.
|
||||||
|
|
||||||
|
## 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.
|
||||||
|
|
||||||
|
Similarly, the loose parser allows plugins to register themselves via
|
||||||
|
`acorn.pluginsLoose`. The extension mechanism is the same as for the
|
||||||
|
normal parser:
|
||||||
|
|
||||||
|
```javascript
|
||||||
|
looseParser.extend("readToken", function(nextMethod) {
|
||||||
|
return function() {
|
||||||
|
console.log("Reading a token in the loose parser!")
|
||||||
|
return nextMethod.call(this)
|
||||||
|
}
|
||||||
|
})
|
||||||
|
```
|
||||||
|
|
||||||
|
