# @nodelib/fs.scandir
> List files and directories inside the specified directory.
## :bulb: Highlights
The package is aimed at obtaining information about entries in the directory.
* :moneybag: Returns useful information: `name`, `path`, `dirent` and `stats` (optional).
* :gear: On Node.js 10.10+ uses the mechanism without additional calls to determine the entry type. See [`old` and `modern` mode](#old-and-modern-mode).
* :link: Can safely work with broken symbolic links.
## Install
```console
npm install @nodelib/fs.scandir
```
## Usage
```ts
import * as fsScandir from '@nodelib/fs.scandir';
fsScandir.scandir('path', (error, stats) => { /* … */ });
```
## API
### .scandir(path, [optionsOrSettings], callback)
Returns an array of plain objects ([`Entry`](#entry)) with information about entry for provided path with standard callback-style.
```ts
fsScandir.scandir('path', (error, entries) => { /* … */ });
fsScandir.scandir('path', {}, (error, entries) => { /* … */ });
fsScandir.scandir('path', new fsScandir.Settings(), (error, entries) => { /* … */ });
```
### .scandirSync(path, [optionsOrSettings])
Returns an array of plain objects ([`Entry`](#entry)) with information about entry for provided path.
```ts
const entries = fsScandir.scandirSync('path');
const entries = fsScandir.scandirSync('path', {});
const entries = fsScandir.scandirSync(('path', new fsScandir.Settings());
```
#### path
* Required: `true`
* Type: `string | Buffer | URL`
A path to a file. If a URL is provided, it must use the `file:` protocol.
#### optionsOrSettings
* Required: `false`
* Type: `Options | Settings`
* Default: An instance of `Settings` class
An [`Options`](#options) object or an instance of [`Settings`](#settingsoptions) class.
> :book: When you pass a plain object, an instance of the `Settings` class will be created automatically. If you plan to call the method frequently, use a pre-created instance of the `Settings` class.
### Settings([options])
A class of full settings of the package.
```ts
const settings = new fsScandir.Settings({ followSymbolicLinks: false });
const entries = fsScandir.scandirSync('path', settings);
```
## Entry
* `name` — The name of the entry (`unknown.txt`).
* `path` — The path of the entry relative to call directory (`root/unknown.txt`).
* `dirent` — An instance of [`fs.Dirent`](./src/types/index.ts) class. On Node.js below 10.10 will be emulated by [`DirentFromStats`](./src/utils/fs.ts) class.
* `stats` (optional) — An instance of `fs.Stats` class.
For example, the `scandir` call for `tools` directory with one directory inside:
```ts
{
dirent: Dirent { name: 'typedoc', /* … */ },
name: 'typedoc',
path: 'tools/typedoc'
}
```
## Options
### stats
* Type: `boolean`
* Default: `false`
Adds an instance of `fs.Stats` class to the [`Entry`](#entry).
> :book: Always use `fs.readdir` without the `withFileTypes` option. ??TODO??
### followSymbolicLinks
* Type: `boolean`
* Default: `false`
Follow symbolic links or not. Call `fs.stat` on symbolic link if `true`.
### `throwErrorOnBrokenSymbolicLink`
* Type: `boolean`
* Default: `true`
Throw an error when symbolic link is broken if `true` or safely use `lstat` call if `false`.
### `pathSegmentSeparator`
* Type: `string`
* Default: `path.sep`
By default, this package uses the correct path separator for your OS (`\` on Windows, `/` on Unix-like systems). But you can set this option to any separator character(s) that you want to use instead.
### `fs`
* Type: [`FileSystemAdapter`](./src/adapters/fs.ts)
* Default: A default FS methods
By default, the built-in Node.js module (`fs`) is used to work with the file system. You can replace any method with your own.
```ts
interface FileSystemAdapter {
lstat?: typeof fs.lstat;
stat?: typeof fs.stat;
lstatSync?: typeof fs.lstatSync;
statSync?: typeof fs.statSync;
readdir?: typeof fs.readdir;
readdirSync?: typeof fs.readdirSync;
}
const settings = new fsScandir.Settings({
fs: { lstat: fakeLstat }
});
```
## `old` and `modern` mode
This package has two modes that are used depending on the environment and parameters of use.
### old
* Node.js below `10.10` or when the `stats` option is enabled
When working in the old mode, the directory is read first (`fs.readdir`), then the type of entries is determined (`fs.lstat` and/or `fs.stat` for symbolic links).
### modern
* Node.js 10.10+ and the `stats` option is disabled
In the modern mode, reading the directory (`fs.readdir` with the `withFileTypes` option) is combined with obtaining information about its entries. An additional call for symbolic links (`fs.stat`) is still present.
This mode makes fewer calls to the file system. It's faster.

# @nodelib/fs.stat
> Get the status of a file with some features.
## :bulb: Highlights
Wrapper around standard method `fs.lstat` and `fs.stat` with some features.
* :beginner: Normally follows symbolic link.
* :gear: Can safely work with broken symbolic link.
## Install
```console
npm install @nodelib/fs.stat
```
## Usage
```ts
import * as fsStat from '@nodelib/fs.stat';
fsStat.stat('path', (error, stats) => { /* … */ });
```
## API
### .stat(path, [optionsOrSettings], callback)
Returns an instance of `fs.Stats` class for provided path with standard callback-style.
```ts
fsStat.stat('path', (error, stats) => { /* … */ });
fsStat.stat('path', {}, (error, stats) => { /* … */ });
fsStat.stat('path', new fsStat.Settings(), (error, stats) => { /* … */ });
```
### .statSync(path, [optionsOrSettings])
Returns an instance of `fs.Stats` class for provided path.
```ts
const stats = fsStat.stat('path');
const stats = fsStat.stat('path', {});
const stats = fsStat.stat('path', new fsStat.Settings());
```
#### path
* Required: `true`
* Type: `string | Buffer | URL`
A path to a file. If a URL is provided, it must use the `file:` protocol.
#### optionsOrSettings
* Required: `false`
* Type: `Options | Settings`
* Default: An instance of `Settings` class
An [`Options`](#options) object or an instance of [`Settings`](#settings) class.
> :book: When you pass a plain object, an instance of the `Settings` class will be created automatically. If you plan to call the method frequently, use a pre-created instance of the `Settings` class.
### Settings([options])
A class of full settings of the package.
```ts
const settings = new fsStat.Settings({ followSymbolicLink: false });
const stats = fsStat.stat('path', settings);
```
## Options
### `followSymbolicLink`
* Type: `boolean`
* Default: `true`
Follow symbolic link or not. Call `fs.stat` on symbolic link if `true`.
### `markSymbolicLink`
* Type: `boolean`
* Default: `false`
Mark symbolic link by setting the return value of `isSymbolicLink` function to always `true` (even after `fs.stat`).
> :book: Can be used if you want to know what is hidden behind a symbolic link, but still continue to know that it is a symbolic link.
### `throwErrorOnBrokenSymbolicLink`
* Type: `boolean`
* Default: `true`
Throw an error when symbolic link is broken if `true` or safely return `lstat` call if `false`.
### `fs`
* Type: [`FileSystemAdapter`](./src/adapters/fs.ts)
* Default: A default FS methods
By default, the built-in Node.js module (`fs`) is used to work with the file system. You can replace any method with your own.
```ts
interface FileSystemAdapter {
lstat?: typeof fs.lstat;
stat?: typeof fs.stat;
lstatSync?: typeof fs.lstatSync;
statSync?: typeof fs.statSync;
}
const settings = new fsStat.Settings({
fs: { lstat: fakeLstat }
});
```

# @nodelib/fs.walk
> A library for efficiently walking a directory recursively.
## :bulb: Highlights
* :moneybag: Returns useful information: `name`, `path`, `dirent` and `stats` (optional).
* :rocket: On Node.js 10.10+ uses the mechanism without additional calls to determine the entry type for performance reasons. See [`old` and `modern` mode](https://github.com/nodelib/nodelib/blob/master/packages/fs/fs.scandir/README.md#old-and-modern-mode).
* :gear: Built-in directories/files and error filtering system.
* :link: Can safely work with broken symbolic links.
## Install
```console
npm install @nodelib/fs.walk
```
## Usage
```ts
import * as fsWalk from '@nodelib/fs.walk';
fsWalk.walk('path', (error, entries) => { /* … */ });
```
## API
### .walk(path, [optionsOrSettings], callback)
Reads the directory recursively and asynchronously. Requires a callback function.
> :book: If you want to use the Promise API, use `util.promisify`.
```ts
fsWalk.walk('path', (error, entries) => { /* … */ });
fsWalk.walk('path', {}, (error, entries) => { /* … */ });
fsWalk.walk('path', new fsWalk.Settings(), (error, entries) => { /* … */ });
```
### .walkStream(path, [optionsOrSettings])
Reads the directory recursively and asynchronously. [Readable Stream](https://nodejs.org/dist/latest-v12.x/docs/api/stream.html#stream_readable_streams) is used as a provider.
```ts
const stream = fsWalk.walkStream('path');
const stream = fsWalk.walkStream('path', {});
const stream = fsWalk.walkStream('path', new fsWalk.Settings());
```
### .walkSync(path, [optionsOrSettings])
Reads the directory recursively and synchronously. Returns an array of entries.
```ts
const entries = fsWalk.walkSync('path');
const entries = fsWalk.walkSync('path', {});
const entries = fsWalk.walkSync('path', new fsWalk.Settings());
```
#### path
* Required: `true`
* Type: `string | Buffer | URL`
A path to a file. If a URL is provided, it must use the `file:` protocol.
#### optionsOrSettings
* Required: `false`
* Type: `Options | Settings`
* Default: An instance of `Settings` class
An [`Options`](#options) object or an instance of [`Settings`](#settings) class.
> :book: When you pass a plain object, an instance of the `Settings` class will be created automatically. If you plan to call the method frequently, use a pre-created instance of the `Settings` class.
### Settings([options])
A class of full settings of the package.
```ts
const settings = new fsWalk.Settings({ followSymbolicLinks: true });
const entries = fsWalk.walkSync('path', settings);
```
## Entry
* `name` — The name of the entry (`unknown.txt`).
* `path` — The path of the entry relative to call directory (`root/unknown.txt`).
* `dirent` — An instance of [`fs.Dirent`](./src/types/index.ts) class.
* [`stats`] — An instance of `fs.Stats` class.
## Options
### basePath
* Type: `string`
* Default: `undefined`
By default, all paths are built relative to the root path. You can use this option to set custom root path.
In the example below we read the files from the `root` directory, but in the results the root path will be `custom`.
```ts
fsWalk.walkSync('root'); // → ['root/file.txt']
fsWalk.walkSync('root', { basePath: 'custom' }); // → ['custom/file.txt']
```
### concurrency
* Type: `number`
* Default: `Infinity`
The maximum number of concurrent calls to `fs.readdir`.
> :book: The higher the number, the higher performance and the load on the File System. If you want to read in quiet mode, set the value to `4 * os.cpus().length` (4 is default size of [thread pool work scheduling](http://docs.libuv.org/en/v1.x/threadpool.html#thread-pool-work-scheduling)).
### deepFilter
* Type: [`DeepFilterFunction`](./src/settings.ts)
* Default: `undefined`
A function that indicates whether the directory will be read deep or not.
```ts
// Skip all directories that starts with `node_modules`
const filter: DeepFilterFunction = (entry) => !entry.path.startsWith('node_modules');
```
### entryFilter
* Type: [`EntryFilterFunction`](./src/settings.ts)
* Default: `undefined`
A function that indicates whether the entry will be included to results or not.
```ts
// Exclude all `.js` files from results
const filter: EntryFilterFunction = (entry) => !entry.name.endsWith('.js');
```
### errorFilter
* Type: [`ErrorFilterFunction`](./src/settings.ts)
* Default: `undefined`
A function that allows you to skip errors that occur when reading directories.
For example, you can skip `ENOENT` errors if required:
```ts
// Skip all ENOENT errors
const filter: ErrorFilterFunction = (error) => error.code == 'ENOENT';
```
### stats
* Type: `boolean`
* Default: `false`
Adds an instance of `fs.Stats` class to the [`Entry`](#entry).
> :book: Always use `fs.readdir` with additional `fs.lstat/fs.stat` calls to determine the entry type.
### followSymbolicLinks
* Type: `boolean`
* Default: `false`
Follow symbolic links or not. Call `fs.stat` on symbolic link if `true`.
### `throwErrorOnBrokenSymbolicLink`
* Type: `boolean`
* Default: `true`
Throw an error when symbolic link is broken if `true` or safely return `lstat` call if `false`.
### `pathSegmentSeparator`
* Type: `string`
* Default: `path.sep`
By default, this package uses the correct path separator for your OS (`\` on Windows, `/` on Unix-like systems). But you can set this option to any separator character(s) that you want to use instead.
### `fs`
* Type: `FileSystemAdapter`
* Default: A default FS methods
By default, the built-in Node.js module (`fs`) is used to work with the file system. You can replace any method with your own.
```ts
interface FileSystemAdapter {
lstat: typeof fs.lstat;
stat: typeof fs.stat;
lstatSync: typeof fs.lstatSync;
statSync: typeof fs.statSync;
readdir: typeof fs.readdir;
readdirSync: typeof fs.readdirSync;
}
const settings = new fsWalk.Settings({
fs: { lstat: fakeLstat }
});
```

# acorn-node change log
All notable changes to this project will be documented in this file.
This project adheres to [Semantic Versioning](http://semver.org/).
## 1.8.2
* Revert a breaking change in import.meta parsing.
## 1.8.1
* Fix crash in compiled private-class-elements code.
## 1.8.0
* Upgrade acorn to v7.
For backwards compatibility, `acorn-node` still uses the `Import` node type for dynamic imports, _NOT_ `ImportExpression` like acorn v7 and estree.
* Add numeric separator support:
```js
var a = 10_000_000_000_000_000_000_000_000n;
```
## 1.7.0
* Add class instance fields support:
```js
class X {
pub = 1;
#priv = 2;
}
```
* Add class static fields support:
```js
class X {
static pub = 1;
static #priv = 2;
}
```
* Add `export * as ns` support when `sourceType` is 'module':
```js
export * as ns from './ns.mjs';
```
## 1.6.2
* Allow dynamic `import()` in scripts.
* Update minimum dependency versions, fixing a peerDependency warning.
* Add Node 10 and 11 to CI.
## 1.6.1
* Update acorn-dynamic-import to v4.
## 1.6.0
* Upgrade acorn to v6.
* Add bigint support.
## 1.5.2
* Upgrade acorn to support optional catch binding in the AST walker.
## 1.5.1
* Fix tests on Node <= 0.12.
## 1.5.0
* Add tests for async iteration, optional catch binding, import.meta,
dynamic import, bigint (currently unsupported).
* Add import.meta support. (`sourceType: 'module'` only)
* Add dynamic import support. (`sourceType: 'module'` only)
* Fix optional catch binding support in the walker.
## 1.4.0
* Upgrade acorn to 5.6, which supports optional catch bindings and other
new syntax features.
* Set ecmaVersion to 2019 to opt in to optional catch bindings etc.
## 1.3.0

# acorn-node
[Acorn](https://github.com/acornjs/acorn) preloaded with plugins for syntax parity with recent Node versions.
It also includes versions of the plugins compiled with [Bublé](https://github.com/rich-harris/buble), so they can be run on old Node versions (0.6 and up).
[![npm][npm-image]][npm-url]
[![travis][travis-image]][travis-url]
[![standard][standard-image]][standard-url]
[npm-image]: https://img.shields.io/npm/v/acorn-node.svg?style=flat-square
[npm-url]: https://www.npmjs.com/package/acorn-node
[travis-image]: https://img.shields.io/travis/browserify/acorn-node/master.svg?style=flat-square

[standard-image]: https://img.shields.io/badge/code%20style-standard-brightgreen.svg?style=flat-square
[standard-url]: http://npm.im/standard
## Install
```
npm install acorn-node
```
## Usage
```js
var acorn = require('acorn-node')
```
The API is the same as [acorn](https://github.com/acornjs/acorn), but the following syntax features are enabled by default:
- Bigint syntax `10n`
- Numeric separators syntax `10_000`
- Public and private class instance fields
- Public and private class static fields
- Dynamic `import()`
- The `import.meta` property
- `export * as ns from` syntax
And the following options have different defaults from acorn, to match Node modules:
- `ecmaVersion: 2019`
- `allowHashBang: true`
- `allowReturnOutsideFunction: true`
```js
var walk = require('acorn-node/walk')
```
The Acorn syntax tree walker. Comes preconfigured for the syntax plugins if necessary.
See the [acorn documentation](https://github.com/acornjs/acorn#distwalkjs) for details.

# Acorn AST walker
An abstract syntax tree walker for the
[ESTree](https://github.com/estree/estree) format.
## Community
Acorn is open source software released under an
[MIT license](https://github.com/acornjs/acorn/blob/master/acorn-walk/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-walk
```
Alternately, you can download the source and build acorn yourself:
```sh
git clone https://github.com/acornjs/acorn.git
cd acorn
npm install
```
## Interface
An algorithm for recursing through a syntax tree is stored as an
object, with a property for each tree node type holding a function
that will recurse through such a node. There are several ways to run
such a walker.
**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](https://github.com/estree/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-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-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-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).
