# Color Contast Checker
An accessibility checker tool for validating the color contrast based on WCAG 2.0 and WCAG 2.1 standard.
The formula (L1/L2) for contrast is based on [ISO-9241-3] and [ANSI-HFES-100-1988] standards as described here :
http://www.w3.org/TR/2008/REC-WCAG20-20081211/#relativeluminancedef
http://www.w3.org/TR/WCAG20/#contrast-ratiodef
https://www.w3.org/TR/WCAG21/#contrast-minimum
It also supports shorthand color codes e.g #FFF or #000 etc.
https://www.w3.org/TR/2001/WD-css3-color-20010305#colorunits
Installation:
------------
```
npm install color-contrast-checker
```
or using package.json
```
{
"name": "my-app",
..
"devDependencies": {
..
"color-contrast-checker": "2.1.0"
}
}
```
Then do `npm install`
Usage:
-----
To check specific WCAG levels
```
var ccc = new ColorContrastChecker();
var color1 = "#FFFFFF";
var color2 = "#000000;
if (ccc.isLevelAA(color1, color2, 14)) {
alert("Valid Level AA");
} else {
alert("Invalid Contrast");
}
```
To check custom ratios
```
var ccc = new ColorContrastChecker();
var color1 = "#FFFFFF";
var color2 = "#000000;
var customRatio = 5.7;
// No need for font size, now that we are using a custom ratio.
// This is because we are no longer checking against WCAG requirements.
if (ccc.isLevelCustom(color1, color2, customRatio)) {
alert("Above given ratio");
} else {
alert("Invalid Contrast");
}
```
Advanced Usage:
--------------
You can pass pairs and get results:
```
var pairs = [
{
'colorA': '#000000',
'colorB': '#000000', // All should fail
'fontSize': 14
},
{
'colorA': '#000000',
'colorB': '#FFFFFF', //All should pass
'fontSize': 14
},
{
'colorA': '#000000',
'colorB': '#848484', //AAA should fail
'fontSize': 14
},
{
'colorA': '#000000',
'colorB': '#848484', //All should pass (because of font)
'fontSize': 19
},
{
'colorA': '#000000',
'colorB': '#757575', //AA should pass AAA should fail
'fontSize': 14
},
{
'colorA': '#000000',
'colorB': '#656565', //All should fail
'fontSize': 14
}
];
var results = ccc.checkPairs(pairs);
```
The result will look like this:
```
[
{
'WCAG_AA' : false,
'WCAG_AAA': false
},
{
'WCAG_AA' : true,
'WCAG_AAA': true
},
{
'WCAG_AA' : true,
'WCAG_AAA': false
},
{
'WCAG_AA' : true,
'WCAG_AAA': true
},
{
'WCAG_AA' : true,
'WCAG_AAA': false
},
{
'WCAG_AA' : false,
'WCAG_AAA': false
}
]
```
## Tests

A cross platform solution to node's spawn and spawnSync.
## Installation
Node.js version 8 and up:
`$ npm install cross-spawn`
Node.js version 7 and under:
`$ npm install cross-spawn@6`
## Why
Node has issues when using spawn on Windows:
- It ignores [PATHEXT](https://github.com/joyent/node/issues/2318)
- It does not support [shebangs](https://en.wikipedia.org/wiki/Shebang_(Unix))
- Has problems running commands with [spaces](https://github.com/nodejs/node/issues/7367)
- Has problems running commands with posix relative paths (e.g.: `./my-folder/my-executable`)
- Has an [issue](https://github.com/moxystudio/node-cross-spawn/issues/82) with command shims (files in `node_modules/.bin/`), where arguments with quotes and parenthesis would result in [invalid syntax error](https://github.com/moxystudio/node-cross-spawn/blob/e77b8f22a416db46b6196767bcd35601d7e11d54/test/index.test.js#L149)
- No `options.shell` support on node `<v4.8`
All these issues are handled correctly by `cross-spawn`.
There are some known modules, such as [win-spawn](https://github.com/ForbesLindesay/win-spawn), that try to solve this but they are either broken or provide faulty escaping of shell arguments.
## Usage
Exactly the same way as node's [`spawn`](https://nodejs.org/api/child_process.html#child_process_child_process_spawn_command_args_options) or [`spawnSync`](https://nodejs.org/api/child_process.html#child_process_child_process_spawnsync_command_args_options), so it's a drop in replacement.
```js
const spawn = require('cross-spawn');
// Spawn NPM asynchronously
const child = spawn('npm', ['list', '-g', '-depth', '0'], { stdio: 'inherit' });
// Spawn NPM synchronously
const result = spawn.sync('npm', ['list', '-g', '-depth', '0'], { stdio: 'inherit' });
```
## Caveats
### Using `options.shell` as an alternative to `cross-spawn`
Starting from node `v4.8`, `spawn` has a `shell` option that allows you run commands from within a shell. This new option solves
the [PATHEXT](https://github.com/joyent/node/issues/2318) issue but:
- It's not supported in node `<v4.8`
- You must manually escape the command and arguments which is very error prone, specially when passing user input
- There are a lot of other unresolved issues from the [Why](#why) section that you must take into account
If you are using the `shell` option to spawn a command in a cross platform way, consider using `cross-spawn` instead. You have been warned.
### `options.shell` support
While `cross-spawn` adds support for `options.shell` in node `<v4.8`, all of its enhancements are disabled.
This mimics the Node.js behavior. More specifically, the command and its arguments will not be automatically escaped nor shebang support will be offered. This is by design because if you are using `options.shell` you are probably targeting a specific platform anyway and you don't want things to get into your way.
### Shebangs support
While `cross-spawn` handles shebangs on Windows, its support is limited. More specifically, it just supports `#!/usr/bin/env <program>` where `<program>` must not contain any arguments.
If you would like to have the shebang support improved, feel free to contribute via a pull-request.
Remember to always test your code on Windows!
## Tests
`$ npm test`
`$ npm test -- --watch` during development

[![Coverage Status](https://codecov.io/gh/sindresorhus/execa/branch/main/graph/badge.svg)](https://codecov.io/gh/sindresorhus/execa)
> Process execution for humans
## Why
This package improves [`child_process`](https://nodejs.org/api/child_process.html) methods with:
- Promise interface.
- [Strips the final newline](#stripfinalnewline) from the output so you don't have to do `stdout.trim()`.
- Supports [shebang](https://en.wikipedia.org/wiki/Shebang_(Unix)) binaries cross-platform.
- [Improved Windows support.](https://github.com/IndigoUnited/node-cross-spawn#why)
- Higher max buffer. 100 MB instead of 200 KB.
- [Executes locally installed binaries by name.](#preferlocal)
- [Cleans up spawned processes when the parent process dies.](#cleanup)
- [Get interleaved output](#all) from `stdout` and `stderr` similar to what is printed on the terminal. [*(Async only)*](#execasyncfile-arguments-options)
- [Can specify file and arguments as a single string without a shell](#execacommandcommand-options)
- More descriptive errors.
## Install
```sh
npm install execa
```
## Usage
```js
import {execa} from 'execa';
const {stdout} = await execa('echo', ['unicorns']);
console.log(stdout);
//=> 'unicorns'
```
### Pipe the child process stdout to the parent
```js
import {execa} from 'execa';
execa('echo', ['unicorns']).stdout.pipe(process.stdout);
```
### Handling Errors
```js
import {execa} from 'execa';
// Catching an error
try {
await execa('unknown', ['command']);
} catch (error) {
console.log(error);
/*
{
message: 'Command failed with ENOENT: unknown command spawn unknown ENOENT',
errno: -2,
code: 'ENOENT',
syscall: 'spawn unknown',
path: 'unknown',
spawnargs: ['command'],
originalMessage: 'spawn unknown ENOENT',
shortMessage: 'Command failed with ENOENT: unknown command spawn unknown ENOENT',
command: 'unknown command',
escapedCommand: 'unknown command',
stdout: '',
stderr: '',
all: '',
failed: true,
timedOut: false,
isCanceled: false,
killed: false
}
*/
}
```
### Cancelling a spawned process
```js
import {execa} from 'execa';
const abortController = new AbortController();
const subprocess = execa('node', [], {signal: abortController.signal});
setTimeout(() => {
abortController.abort();
}, 1000);
try {
await subprocess;
} catch (error) {
console.log(subprocess.killed); // true
console.log(error.isCanceled); // true
}
```
### Catching an error with the sync method
```js
import {execaSync} from 'execa';
try {
execaSync('unknown', ['command']);
} catch (error) {
console.log(error);
/*
{
message: 'Command failed with ENOENT: unknown command spawnSync unknown ENOENT',
errno: -2,
code: 'ENOENT',
syscall: 'spawnSync unknown',
path: 'unknown',
spawnargs: ['command'],
originalMessage: 'spawnSync unknown ENOENT',
shortMessage: 'Command failed with ENOENT: unknown command spawnSync unknown ENOENT',
command: 'unknown command',
escapedCommand: 'unknown command',
stdout: '',
stderr: '',
all: '',
failed: true,
timedOut: false,
isCanceled: false,
killed: false
}
*/
}
```
### Kill a process
Using SIGTERM, and after 2 seconds, kill it with SIGKILL.
```js
const subprocess = execa('node');
setTimeout(() => {
subprocess.kill('SIGTERM', {
forceKillAfterTimeout: 2000
});
}, 1000);
```
## API
### execa(file, arguments, options?)
Execute a file. Think of this as a mix of [`child_process.execFile()`](https://nodejs.org/api/child_process.html#child_process_child_process_execfile_file_args_options_callback) and [`child_process.spawn()`](https://nodejs.org/api/child_process.html#child_process_child_process_spawn_command_args_options).
No escaping/quoting is needed.
Unless the [`shell`](#shell) option is used, no shell interpreter (Bash, `cmd.exe`, etc.) is used, so shell features such as variables substitution (`echo $PATH`) are not allowed.
Returns a [`child_process` instance](https://nodejs.org/api/child_process.html#child_process_class_childprocess) which:
- is also a `Promise` resolving or rejecting with a [`childProcessResult`](#childProcessResult).
- exposes the following additional methods and properties.
#### kill(signal?, options?)
Same as the original [`child_process#kill()`](https://nodejs.org/api/child_process.html#child_process_subprocess_kill_signal) except: if `signal` is `SIGTERM` (the default value) and the child process is not terminated after 5 seconds, force it by sending `SIGKILL`.
##### options.forceKillAfterTimeout
Type: `number | false`\
Default: `5000`
Milliseconds to wait for the child process to terminate before sending `SIGKILL`.
Can be disabled with `false`.
#### all
Type: `ReadableStream | undefined`
Stream combining/interleaving [`stdout`](https://nodejs.org/api/child_process.html#child_process_subprocess_stdout) and [`stderr`](https://nodejs.org/api/child_process.html#child_process_subprocess_stderr).
This is `undefined` if either:
- the [`all` option](#all-2) is `false` (the default value)
- both [`stdout`](#stdout-1) and [`stderr`](#stderr-1) options are set to [`'inherit'`, `'ipc'`, `Stream` or `integer`](https://nodejs.org/dist/latest-v6.x/docs/api/child_process.html#child_process_options_stdio)
### execaSync(file, arguments?, options?)
Execute a file synchronously.
Returns or throws a [`childProcessResult`](#childProcessResult).
### execaCommand(command, options?)
Same as [`execa()`](#execafile-arguments-options) except both file and arguments are specified in a single `command` string. For example, `execa('echo', ['unicorns'])` is the same as `execaCommand('echo unicorns')`.
If the file or an argument contains spaces, they must be escaped with backslashes. This matters especially if `command` is not a constant but a variable, for example with `__dirname` or `process.cwd()`. Except for spaces, no escaping/quoting is needed.
The [`shell` option](#shell) must be used if the `command` uses shell-specific features (for example, `&&` or `||`), as opposed to being a simple `file` followed by its `arguments`.
### execaCommandSync(command, options?)
Same as [`execaCommand()`](#execacommand-command-options) but synchronous.
Returns or throws a [`childProcessResult`](#childProcessResult).
### execaNode(scriptPath, arguments?, options?)
Execute a Node.js script as a child process.
Same as `execa('node', [scriptPath, ...arguments], options)` except (like [`child_process#fork()`](https://nodejs.org/api/child_process.html#child_process_child_process_fork_modulepath_args_options)):
- the current Node version and options are used. This can be overridden using the [`nodePath`](#nodepath-for-node-only) and [`nodeOptions`](#nodeoptions-for-node-only) options.
- the [`shell`](#shell) option cannot be used
- an extra channel [`ipc`](https://nodejs.org/api/child_process.html#child_process_options_stdio) is passed to [`stdio`](#stdio)
### childProcessResult
Type: `object`
Result of a child process execution. On success this is a plain object. On failure this is also an `Error` instance.
The child process [fails](#failed) when:
- its [exit code](#exitcode) is not `0`
- it was [killed](#killed) with a [signal](#signal)
- [timing out](#timedout)
- [being canceled](#iscanceled)
- there's not enough memory or there are already too many child processes
#### command
Type: `string`
The file and arguments that were run, for logging purposes.
This is not escaped and should not be executed directly as a process, including using [`execa()`](#execafile-arguments-options) or [`execaCommand()`](#execacommandcommand-options).
#### escapedCommand
Type: `string`
Same as [`command`](#command) but escaped.
This is meant to be copy and pasted into a shell, for debugging purposes.
Since the escaping is fairly basic, this should not be executed directly as a process, including using [`execa()`](#execafile-arguments-options) or [`execaCommand()`](#execacommandcommand-options).
#### exitCode
Type: `number`
The numeric exit code of the process that was run.
#### stdout
Type: `string | Buffer`
The output of the process on stdout.
#### stderr
Type: `string | Buffer`
The output of the process on stderr.
#### all
Type: `string | Buffer | undefined`
The output of the process with `stdout` and `stderr` interleaved.
This is `undefined` if either:
- the [`all` option](#all-2) is `false` (the default value)
- `execaSync()` was used
#### failed
Type: `boolean`
Whether the process failed to run.
#### timedOut
Type: `boolean`
Whether the process timed out.
#### isCanceled
Type: `boolean`
Whether the process was canceled.
You can cancel the spawned process using the [`signal`](#signal-1) option.
#### killed
Type: `boolean`
Whether the process was killed.
#### signal
Type: `string | undefined`
The name of the signal that was used to terminate the process. For example, `SIGFPE`.
If a signal terminated the process, this property is defined and included in the error message. Otherwise it is `undefined`.
#### signalDescription
Type: `string | undefined`
A human-friendly description of the signal that was used to terminate the process. For example, `Floating point arithmetic error`.
If a signal terminated the process, this property is defined and included in the error message. Otherwise it is `undefined`. It is also `undefined` when the signal is very uncommon which should seldomly happen.
#### message
Type: `string`
Error message when the child process failed to run. In addition to the [underlying error message](#originalMessage), it also contains some information related to why the child process errored.
The child process [stderr](#stderr) then [stdout](#stdout) are appended to the end, separated with newlines and not interleaved.
#### shortMessage
Type: `string`
This is the same as the [`message` property](#message) except it does not include the child process stdout/stderr.
#### originalMessage
Type: `string | undefined`
Original error message. This is the same as the `message` property except it includes neither the child process stdout/stderr nor some additional information added by Execa.
This is `undefined` unless the child process exited due to an `error` event or a timeout.
### options
Type: `object`
#### cleanup
Type: `boolean`\
Default: `true`
Kill the spawned process when the parent process exits unless either:
- the spawned process is [`detached`](https://nodejs.org/api/child_process.html#child_process_options_detached)
- the parent process is terminated abruptly, for example, with `SIGKILL` as opposed to `SIGTERM` or a normal exit
#### preferLocal
Type: `boolean`\
Default: `false`
Prefer locally installed binaries when looking for a binary to execute.\
If you `$ npm install foo`, you can then `execa('foo')`.
#### localDir
Type: `string | URL`\
Default: `process.cwd()`
Preferred path to find locally installed binaries in (use with `preferLocal`).
Using a `URL` is only supported in Node.js `14.18.0`, `16.14.0` or above.
#### execPath
Type: `string`\
Default: `process.execPath` (Current Node.js executable)
Path to the Node.js executable to use in child processes.
This can be either an absolute path or a path relative to the [`cwd` option](#cwd).
Requires [`preferLocal`](#preferlocal) to be `true`.
For example, this can be used together with [`get-node`](https://github.com/ehmicky/get-node) to run a specific Node.js version in a child process.
#### buffer
Type: `boolean`\
Default: `true`
Buffer the output from the spawned process. When set to `false`, you must read the output of [`stdout`](#stdout-1) and [`stderr`](#stderr-1) (or [`all`](#all) if the [`all`](#all-2) option is `true`). Otherwise the returned promise will not be resolved/rejected.
If the spawned process fails, [`error.stdout`](#stdout), [`error.stderr`](#stderr), and [`error.all`](#all) will contain the buffered data.
#### input
Type: `string | Buffer | stream.Readable`
Write some input to the `stdin` of your binary.\
Streams are not allowed when using the synchronous methods.
#### stdin
Type: `string | number | Stream | undefined`\
Default: `pipe`
Same options as [`stdio`](https://nodejs.org/dist/latest-v6.x/docs/api/child_process.html#child_process_options_stdio).
#### stdout
Type: `string | number | Stream | undefined`\
Default: `pipe`
Same options as [`stdio`](https://nodejs.org/dist/latest-v6.x/docs/api/child_process.html#child_process_options_stdio).
#### stderr
Type: `string | number | Stream | undefined`\
Default: `pipe`
Same options as [`stdio`](https://nodejs.org/dist/latest-v6.x/docs/api/child_process.html#child_process_options_stdio).
#### all
Type: `boolean`\
Default: `false`
Add an `.all` property on the [promise](#all) and the [resolved value](#all-1). The property contains the output of the process with `stdout` and `stderr` interleaved.
#### reject
Type: `boolean`\
Default: `true`
Setting this to `false` resolves the promise with the error instead of rejecting it.
#### stripFinalNewline
Type: `boolean`\
Default: `true`
Strip the final [newline character](https://en.wikipedia.org/wiki/Newline) from the output.
#### extendEnv
Type: `boolean`\
Default: `true`
Set to `false` if you don't want to extend the environment variables when providing the `env` property.
---
Execa also accepts the below options which are the same as the options for [`child_process#spawn()`](https://nodejs.org/api/child_process.html#child_process_child_process_spawn_command_args_options)/[`child_process#exec()`](https://nodejs.org/api/child_process.html#child_process_child_process_exec_command_options_callback)
#### cwd
Type: `string | URL`\
Default: `process.cwd()`
Current working directory of the child process.
Using a `URL` is only supported in Node.js `14.18.0`, `16.14.0` or above.
#### env
Type: `object`\
Default: `process.env`
Environment key-value pairs. Extends automatically from `process.env`. Set [`extendEnv`](#extendenv) to `false` if you don't want this.
#### argv0
Type: `string`
Explicitly set the value of `argv[0]` sent to the child process. This will be set to `file` if not specified.
#### stdio
Type: `string | string[]`\
Default: `pipe`
Child's [stdio](https://nodejs.org/api/child_process.html#child_process_options_stdio) configuration.
#### serialization
Type: `string`\
Default: `'json'`
Specify the kind of serialization used for sending messages between processes when using the [`stdio: 'ipc'`](#stdio) option or [`execaNode()`](#execanodescriptpath-arguments-options):
- `json`: Uses `JSON.stringify()` and `JSON.parse()`.
- `advanced`: Uses [`v8.serialize()`](https://nodejs.org/api/v8.html#v8_v8_serialize_value)
Requires Node.js `13.2.0` or later.
[More info.](https://nodejs.org/api/child_process.html#child_process_advanced_serialization)
#### detached
Type: `boolean`
Prepare child to run independently of its parent process. Specific behavior [depends on the platform](https://nodejs.org/api/child_process.html#child_process_options_detached).
#### uid
Type: `number`
Sets the user identity of the process.
#### gid
Type: `number`
Sets the group identity of the process.
#### shell
Type: `boolean | string`\
Default: `false`
If `true`, runs `file` inside of a shell. Uses `/bin/sh` on UNIX and `cmd.exe` on Windows. A different shell can be specified as a string. The shell should understand the `-c` switch on UNIX or `/d /s /c` on Windows.
We recommend against using this option since it is:
- not cross-platform, encouraging shell-specific syntax.
- slower, because of the additional shell interpretation.
- unsafe, potentially allowing command injection.
#### encoding
Type: `string | null`\
Default: `utf8`
Specify the character encoding used to decode the `stdout` and `stderr` output. If set to `null`, then `stdout` and `stderr` will be a `Buffer` instead of a string.
#### timeout
Type: `number`\
Default: `0`
If timeout is greater than `0`, the parent will send the signal identified by the `killSignal` property (the default is `SIGTERM`) if the child runs longer than timeout milliseconds.
#### maxBuffer
Type: `number`\
Default: `100_000_000` (100 MB)
Largest amount of data in bytes allowed on `stdout` or `stderr`.
#### killSignal
Type: `string | number`\
Default: `SIGTERM`
Signal value to be used when the spawned process will be killed.
#### signal
Type: [`AbortSignal`](https://developer.mozilla.org/en-US/docs/Web/API/AbortSignal)
You can abort the spawned process using [`AbortController`](https://developer.mozilla.org/en-US/docs/Web/API/AbortController).
When `AbortController.abort()` is called, [`.isCanceled`](#iscanceled) becomes `false`.
*Requires Node.js 16 or later.*
#### windowsVerbatimArguments
Type: `boolean`\
Default: `false`
If `true`, no quoting or escaping of arguments is done on Windows. Ignored on other platforms. This is set to `true` automatically when the `shell` option is `true`.
#### windowsHide
Type: `boolean`\
Default: `true`
On Windows, do not create a new console window. Please note this also prevents `CTRL-C` [from working](https://github.com/nodejs/node/issues/29837) on Windows.
#### nodePath *(For `.node()` only)*
Type: `string`\
Default: [`process.execPath`](https://nodejs.org/api/process.html#process_process_execpath)
Node.js executable used to create the child process.
#### nodeOptions *(For `.node()` only)*
Type: `string[]`\
Default: [`process.execArgv`](https://nodejs.org/api/process.html#process_process_execargv)
List of [CLI options](https://nodejs.org/api/cli.html#cli_options) passed to the Node.js executable.
## Tips
### Retry on error
Gracefully handle failures by using automatic retries and exponential backoff with the [`p-retry`](https://github.com/sindresorhus/p-retry) package:
```js
import pRetry from 'p-retry';
const run = async () => {
const results = await execa('curl', ['-sSL', 'https://sindresorhus.com/unicorn']);
return results;
};
console.log(await pRetry(run, {retries: 5}));
```
### Save and pipe output from a child process
Let's say you want to show the output of a child process in real-time while also saving it to a variable.
```js
import {execa} from 'execa';
const subprocess = execa('echo', ['foo']);
subprocess.stdout.pipe(process.stdout);
const {stdout} = await subprocess;
console.log('child output:', stdout);
```
### Redirect output to a file
```js
import {execa} from 'execa';
const subprocess = execa('echo', ['foo'])
subprocess.stdout.pipe(fs.createWriteStream('stdout.txt'))
```
### Redirect input from a file
```js
import {execa} from 'execa';
const subprocess = execa('cat')
fs.createReadStream('stdin.txt').pipe(subprocess.stdin)
```
### Execute the current package's binary
```js
import {getBinPathSync} from 'get-bin-path';
const binPath = getBinPathSync();
const subprocess = execa(binPath);
```
`execa` can be combined with [`get-bin-path`](https://github.com/ehmicky/get-bin-path) to test the current package's binary. As opposed to hard-coding the path to the binary, this validates that the `package.json` `bin` field is correctly set up.

## API
The methods returns a promise that resolves when the `end` event fires on the stream, indicating that there is no more data to be read. The stream is switched to flowing mode.
### getStream(stream, options?)
Get the `stream` as a string.
#### options
Type: `object`
##### encoding
Type: `string`\
Default: `'utf8'`
[Encoding](https://nodejs.org/api/buffer.html#buffer_buffer) of the incoming stream.
##### maxBuffer
Type: `number`\
Default: `Infinity`
Maximum length of the returned string. If it exceeds this value before the stream ends, the promise will be rejected with a `getStream.MaxBufferError` error.
### getStream.buffer(stream, options?)
Get the `stream` as a buffer.
It honors the `maxBuffer` option as above, but it refers to byte length rather than string length.
### getStream.array(stream, options?)
Get the `stream` as an array of values.
It honors both the `maxBuffer` and `encoding` options. The behavior changes slightly based on the encoding chosen:
- When `encoding` is unset, it assumes an [object mode stream](https://nodesource.com/blog/understanding-object-streams/) and collects values emitted from `stream` unmodified. In this case `maxBuffer` refers to the number of items in the array (not the sum of their sizes).
- When `encoding` is set to `buffer`, it collects an array of buffers. `maxBuffer` refers to the summed byte lengths of every buffer in the array.
- When `encoding` is set to anything else, it collects an array of strings. `maxBuffer` refers to the summed character lengths of every string in the array.
## Errors
If the input stream emits an `error` event, the promise will be rejected with the error. The buffered data will be attached to the `bufferedData` property of the error.
```js
(async () => {
try {
await getStream(streamThatErrorsAtTheEnd('unicorn'));
} catch (error) {
console.log(error.bufferedData);
//=> 'unicorn'
}
})()
```
## FAQ
### How is this different from [`concat-stream`](https://github.com/maxogden/concat-stream)?
This module accepts a stream instead of being one and returns a promise instead of using a callback. The API is simpler and it only supports returning a string, buffer, or array. It doesn't have a fragile type inference. You explicitly choose what you want. And it doesn't depend on the huge `readable-stream` package.

Human-friendly process signals.
This is a map of known process signals with some information about each signal.
Unlike
[`os.constants.signals`](https://nodejs.org/api/os.html#os_signal_constants)
this includes:
- human-friendly [descriptions](#description)
- [default actions](#action), including whether they [can be prevented](#forced)
- whether the signal is [supported](#supported) by the current OS
# Example
```js
import { signalsByName, signalsByNumber } from 'human-signals'
console.log(signalsByName.SIGINT)
// {
// name: 'SIGINT',
// number: 2,
// description: 'User interruption with CTRL-C',
// supported: true,
// action: 'terminate',
// forced: false,
// standard: 'ansi'
// }
console.log(signalsByNumber[8])
// {
// name: 'SIGFPE',
// number: 8,
// description: 'Floating point arithmetic error',
// supported: true,
// action: 'core',
// forced: false,
// standard: 'ansi'
// }
```
# Install
```bash
npm install human-signals
```
This package is an ES module and must be loaded using
[an `import` or `import()` statement](https://gist.github.com/sindresorhus/a39789f98801d908bbc7ff3ecc99d99c),
not `require()`.
# Usage
## signalsByName
_Type_: `object`
Object whose keys are signal [names](#name) and values are
[signal objects](#signal).
## signalsByNumber
_Type_: `object`
Object whose keys are signal [numbers](#number) and values are
[signal objects](#signal).
## signal
_Type_: `object`
Signal object with the following properties.
### name
_Type_: `string`
Standard name of the signal, for example `'SIGINT'`.
### number
_Type_: `number`
Code number of the signal, for example `2`. While most `number` are
cross-platform, some are different between different OS.
### description
_Type_: `string`
Human-friendly description for the signal, for example
`'User interruption with CTRL-C'`.
### supported
_Type_: `boolean`
Whether the current OS can handle this signal in Node.js using
[`process.on(name, handler)`](https://nodejs.org/api/process.html#process_signal_events).
The list of supported signals
[is OS-specific](https://github.com/ehmicky/cross-platform-node-guide/blob/main/docs/6_networking_ipc/signals.md#cross-platform-signals).
### action
_Type_: `string`\
_Enum_: `'terminate'`, `'core'`, `'ignore'`, `'pause'`, `'unpause'`
What is the default action for this signal when it is not handled.
### forced
_Type_: `boolean`
Whether the signal's default action cannot be prevented. This is `true` for
`SIGTERM`, `SIGKILL` and `SIGSTOP`.
### standard
_Type_: `string`\
_Enum_: `'ansi'`, `'posix'`, `'bsd'`, `'systemv'`, `'other'`
Which standard defined that signal.

# isexe
Minimal module to check if a file is executable, and a normal file.
Uses `fs.stat` and tests against the `PATHEXT` environment variable on
Windows.
## USAGE
```javascript
var isexe = require('isexe')
isexe('some-file-name', function (err, isExe) {
if (err) {
console.error('probably file does not exist or something', err)
} else if (isExe) {
console.error('this thing can be run')
} else {
console.error('cannot be run')
}
})
// same thing but synchronous, throws errors
var isExe = isexe.sync('some-file-name')
// treat errors as just "not executable"
isexe('maybe-missing-file', { ignoreErrors: true }, callback)
var isExe = isexe.sync('maybe-missing-file', { ignoreErrors: true })
```
## API
### `isexe(path, [options], [callback])`
Check if the path is executable. If no callback provided, and a
global `Promise` object is available, then a Promise will be returned.
Will raise whatever errors may be raised by `fs.stat`, unless
`options.ignoreErrors` is set to true.
### `isexe.sync(path, [options])`
Same as `isexe` but returns the value and throws any errors raised.
### Options
* `ignoreErrors` Treat all errors as "no, this is not executable", but
don't raise them.
* `uid` Number to use as the user id
* `gid` Number to use as the group id
* `pathExt` List of path extensions to use instead of `PATHEXT`
environment variable on Windows.

# merge-stream
Merge (interleave) a bunch of streams.
[![build status](https://secure.travis-ci.org/grncdr/merge-stream.svg?branch=master)](http://travis-ci.org/grncdr/merge-stream)
## Synopsis
```javascript
var stream1 = new Stream();
var stream2 = new Stream();
var merged = mergeStream(stream1, stream2);
var stream3 = new Stream();
merged.add(stream3);
merged.isEmpty();
//=> false
```
## Description
This is adapted from [event-stream](https://github.com/dominictarr/event-stream) separated into a new module, using Streams3.
## API
### `mergeStream`
Type: `function`
Merges an arbitrary number of streams. Returns a merged stream.
#### `merged.add`
A method to dynamically add more sources to the stream. The argument supplied to `add` can be either a source or an array of sources.
#### `merged.isEmpty`
A method that tells you if the merged stream is empty.
When a stream is "empty" (aka. no sources were added), it could not be returned to a gulp task.
So, we could do something like this:
```js
stream = require('merge-stream')();
// Something like a loop to add some streams to the merge stream
// stream.add(streamA);
// stream.add(streamB);
return stream.isEmpty() ? null : stream;
```
## Gulp example
An example use case for **merge-stream** is to combine parts of a task in a project's **gulpfile.js** like this:
```js
const gulp = require('gulp');
const htmlValidator = require('gulp-w3c-html-validator');
const jsHint = require('gulp-jshint');
const mergeStream = require('merge-stream');
function lint() {
return mergeStream(
gulp.src('src/*.html')
.pipe(htmlValidator())
.pipe(htmlValidator.reporter()),
gulp.src('src/*.js')
.pipe(jsHint())
.pipe(jsHint.reporter())
);
}
gulp.task('lint', lint);
```

> Make a function mimic another one
Useful when you wrap a function in another function and like to preserve the original name and other properties.
## Install
```
$ npm install mimic-fn
```
## Usage
```js
import mimicFunction from 'mimic-fn';
function foo() {}
foo.unicorn = '🦄';
function wrapper() {
return foo();
}
console.log(wrapper.name);
//=> 'wrapper'
mimicFunction(wrapper, foo);

//=> 'foo'
console.log(wrapper.unicorn);
//=> '🦄'
console.log(String(wrapper));
//=> '/* Wrapped with wrapper() */\nfunction foo() {}'
```
## API
### mimicFunction(to, from, options?)
Modifies the `to` function to mimic the `from` function. Returns the `to` function.
`name`, `displayName`, and any other properties of `from` are copied. The `length` property is not copied. Prototype, class, and inherited properties are copied.
`to.toString()` will return the same as `from.toString()` but prepended with a `Wrapped with to()` comment.
#### to
Type: `Function`
Mimicking function.
#### from
Type: `Function`
Function to mimic.
#### options
Type: `object`
##### ignoreNonConfigurable
Type: `boolean`\
Default: `false`
Skip modifying [non-configurable properties](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/getOwnPropertyDescriptor#Description) instead of throwing an error.

# npm-run-path
> Get your [PATH](https://en.wikipedia.org/wiki/PATH_(variable)) prepended with locally installed binaries
In [npm run scripts](https://docs.npmjs.com/cli/run-script) you can execute locally installed binaries by name. This enables the same outside npm.
## Install
```sh
npm install npm-run-path
```
## Usage
```js
import childProcess from 'node:child_process';
import {npmRunPath, npmRunPathEnv} from 'npm-run-path';
console.log(process.env.PATH);
//=> '/usr/local/bin'
console.log(npmRunPath());
//=> '/Users/sindresorhus/dev/foo/node_modules/.bin:/Users/sindresorhus/dev/node_modules/.bin:/Users/sindresorhus/node_modules/.bin:/Users/node_modules/.bin:/node_modules/.bin:/usr/local/bin'
// `foo` is a locally installed binary
childProcess.execFileSync('foo', {
env: npmRunPathEnv()
});
```
## API
### npmRunPath(options?)
Returns the augmented PATH string.
#### options
Type: `object`
##### cwd
Type: `string | URL`\
Default: `process.cwd()`
The working directory.
##### path
Type: `string`\
Default: [`PATH`](https://github.com/sindresorhus/path-key)
The PATH to be appended.
Set it to an empty string to exclude the default PATH.
##### execPath
Type: `string`\
Default: `process.execPath`
The path to the current Node.js executable. Its directory is pushed to the front of PATH.
This can be either an absolute path or a path relative to the [`cwd` option](#cwd).
### npmRunPathEnv(options?)
Returns the augmented [`process.env`](https://nodejs.org/api/process.html#process_process_env) object.
#### options
Type: `object`
##### cwd
Type: `string | URL`\
Default: `process.cwd()`
The working directory.
##### env
Type: `object`
Accepts an object of environment variables, like `process.env`, and modifies the PATH using the correct [PATH key](https://github.com/sindresorhus/path-key). Use this if you're modifying the PATH for use in the `child_process` options.
##### execPath
Type: `string`\
Default: `process.execPath`
The path to the Node.js executable to use in child processes if that is different from the current one. Its directory is pushed to the front of PATH.
This can be either an absolute path or a path relative to the [`cwd` option](#cwd).

# onetime
> Ensure a function is only called once
When called multiple times it will return the return value from the first call.
*Unlike the module [once](https://github.com/isaacs/once), this one isn't naughty and extending `Function.prototype`.*
## Install
```
$ npm install onetime
```
## Usage
```js
import onetime from 'onetime';
let index = 0;
const foo = onetime(() => ++index);
foo(); //=> 1
foo(); //=> 1
foo(); //=> 1
onetime.callCount(foo); //=> 3
```
```js
import onetime from 'onetime';
const foo = onetime(() => {}, {throw: true});
foo();
foo();
//=> Error: Function `foo` can only be called once
```
## API
### onetime(fn, options?)
Returns a function that only calls `fn` once.
#### fn
Type: `Function`
Function that should only be called once.
#### options
Type: `object`
##### throw
Type: `boolean`\
Default: `false`
Throw an error when called more than once.
### onetime.callCount(fn)
Returns a number representing how many times `fn` has been called.
Note: It throws an error if you pass in a function that is not wrapped by `onetime`.
```js
import onetime from 'onetime';
const foo = onetime(() => {});
foo();
foo();
foo();
console.log(onetime.callCount(foo));
//=> 3
```
#### fn
Type: `Function`
Function to get call count from.
