Define argument flags.
The key is the flag name in camel-case and the value is an object with any of:
- `type`: Type of value. (Possible values: `string` `boolean` `number`)
- `alias`: Usually used to define a short flag alias.
- `default`: Default value when the flag is not specified.
- `isRequired`: Determine if the flag is required.
If it's only known at runtime whether the flag is required or not you can pass a Function instead of a boolean, which based on the given flags and other non-flag arguments should decide if the flag is required.
- `isMultiple`: Indicates a flag can be set multiple times. Values are turned into an array. (Default: false)
Multiple values are provided by specifying the flag multiple times, for example, `$ foo -u rainbow -u cat`. Space- or comma-separated values are *not* supported.
Note that flags are always defined using a camel-case key (`myKey`), but will match arguments in kebab-case (`--my-key`).
@example
```
flags: {
unicorn: {
type: 'string',
alias: 'u',
default: ['rainbow', 'cat'],
isMultiple: true,
isRequired: (flags, input) => {
if (flags.otherFlag) {
return true;
}
return false;
}
}

# hosted-git-info
This will let you identify and transform various git hosts URLs between
protocols. It also can tell you what the URL is for the raw path for
particular file for direct access without git.
## Example
```javascript
var hostedGitInfo = require("hosted-git-info")
var info = hostedGitInfo.fromUrl("git@github.com:npm/hosted-git-info.git", opts)
/* info looks like:
{
type: "github",
domain: "github.com",
user: "npm",
project: "hosted-git-info"
}
*/
```
If the URL can't be matched with a git host, `null` will be returned. We
can match git, ssh and https urls. Additionally, we can match ssh connect
strings (`git@github.com:npm/hosted-git-info`) and shortcuts (eg,
`github:npm/hosted-git-info`). GitHub specifically, is detected in the case
of a third, unprefixed, form: `npm/hosted-git-info`.
If it does match, the returned object has properties of:
* info.type -- The short name of the service
* info.domain -- The domain for git protocol use
* info.user -- The name of the user/org on the git host
* info.project -- The name of the project on the git host
## Version Contract
The major version will be bumped any time…
* The constructor stops accepting URLs that it previously accepted.
* A method is removed.
* A method can no longer accept the number and type of arguments it previously accepted.
* A method can return a different type than it currently returns.
Implications:
* I do not consider the specific format of the urls returned from, say
`.https()` to be a part of the contract. The contract is that it will
return a string that can be used to fetch the repo via HTTPS. But what
that string looks like, specifically, can change.
* Dropping support for a hosted git provider would constitute a breaking
change.
## Usage
### var info = hostedGitInfo.fromUrl(gitSpecifier[, options])
* *gitSpecifer* is a URL of a git repository or a SCP-style specifier of one.
* *options* is an optional object. It can have the following properties:
* *noCommittish* — If true then committishes won't be included in generated URLs.
* *noGitPlus* — If true then `git+` won't be prefixed on URLs.
## Methods
All of the methods take the same options as the `fromUrl` factory. Options
provided to a method override those provided to the constructor.
* info.file(path, opts)
Given the path of a file relative to the repository, returns a URL for
directly fetching it from the githost. If no committish was set then
`master` will be used as the default.
For example `hostedGitInfo.fromUrl("git@github.com:npm/hosted-git-info.git#v1.0.0").file("package.json")`
would return `https://raw.githubusercontent.com/npm/hosted-git-info/v1.0.0/package.json`
* info.shortcut(opts)
eg, `github:npm/hosted-git-info`
* info.browse(path, fragment, opts)
eg, `https://github.com/npm/hosted-git-info/tree/v1.2.0`,
`https://github.com/npm/hosted-git-info/tree/v1.2.0/package.json`,
`https://github.com/npm/hosted-git-info/tree/v1.2.0/REAMDE.md#supported-hosts`
* info.bugs(opts)
eg, `https://github.com/npm/hosted-git-info/issues`
* info.docs(opts)
eg, `https://github.com/npm/hosted-git-info/tree/v1.2.0#readme`
* info.https(opts)
eg, `git+https://github.com/npm/hosted-git-info.git`
* info.sshurl(opts)
eg, `git+ssh://git@github.com/npm/hosted-git-info.git`
* info.ssh(opts)
eg, `git@github.com:npm/hosted-git-info.git`
* info.path(opts)
eg, `npm/hosted-git-info`
* info.tarball(opts)
eg, `https://github.com/npm/hosted-git-info/archive/v1.2.0.tar.gz`
* info.getDefaultRepresentation()
Returns the default output type. The default output type is based on the
string you passed in to be parsed
* info.toString(opts)
Uses the getDefaultRepresentation to call one of the other methods to get a URL for
this resource. As such `hostedGitInfo.fromUrl(url).toString()` will give
you a normalized version of the URL that still uses the same protocol.
Shortcuts will still be returned as shortcuts, but the special case github
form of `org/project` will be normalized to `github:org/project`.
SSH connect strings will be normalized into `git+ssh` URLs.
## Supported hosts
Currently this supports GitHub, Bitbucket and GitLab. Pull requests for
additional hosts welcome.

# normalize-package-data
[![Build Status](https://travis-ci.org/npm/normalize-package-data.svg?branch=master)](https://travis-ci.org/npm/normalize-package-data)
normalize-package-data exports a function that normalizes package metadata. This data is typically found in a package.json file, but in principle could come from any source - for example the npm registry.
normalize-package-data is used by [read-package-json](https://npmjs.org/package/read-package-json) to normalize the data it reads from a package.json file. In turn, read-package-json is used by [npm](https://npmjs.org/package/npm) and various npm-related tools.
## Installation
```
npm install normalize-package-data
```
## Usage
Basic usage is really simple. You call the function that normalize-package-data exports. Let's call it `normalizeData`.
```javascript
normalizeData = require('normalize-package-data')
packageData = require("./package.json")
normalizeData(packageData)
// packageData is now normalized
```
#### Strict mode
You may activate strict validation by passing true as the second argument.
```javascript
normalizeData = require('normalize-package-data')
packageData = require("./package.json")
normalizeData(packageData, true)
// packageData is now normalized
```
If strict mode is activated, only Semver 2.0 version strings are accepted. Otherwise, Semver 1.0 strings are accepted as well. Packages must have a name, and the name field must not have contain leading or trailing whitespace.
#### Warnings
Optionally, you may pass a "warning" function. It gets called whenever the `normalizeData` function encounters something that doesn't look right. It indicates less than perfect input data.
```javascript
normalizeData = require('normalize-package-data')
packageData = require("./package.json")
warnFn = function(msg) { console.error(msg) }
normalizeData(packageData, warnFn)
// packageData is now normalized. Any number of warnings may have been logged.
```
You may combine strict validation with warnings by passing `true` as the second argument, and `warnFn` as third.
When `private` field is set to `true`, warnings will be suppressed.
### Potential exceptions
If the supplied data has an invalid name or version vield, `normalizeData` will throw an error. Depending on where you call `normalizeData`, you may want to catch these errors so can pass them to a callback.
## What normalization (currently) entails
* The value of `name` field gets trimmed (unless in strict mode).
* The value of the `version` field gets cleaned by `semver.clean`. See [documentation for the semver module](https://github.com/isaacs/node-semver).
* If `name` and/or `version` fields are missing, they are set to empty strings.
* If `files` field is not an array, it will be removed.
* If `bin` field is a string, then `bin` field will become an object with `name` set to the value of the `name` field, and `bin` set to the original string value.
* If `man` field is a string, it will become an array with the original string as its sole member.
* If `keywords` field is string, it is considered to be a list of keywords separated by one or more white-space characters. It gets converted to an array by splitting on `\s+`.
* All people fields (`author`, `maintainers`, `contributors`) get converted into objects with name, email and url properties.
* If `bundledDependencies` field (a typo) exists and `bundleDependencies` field does not, `bundledDependencies` will get renamed to `bundleDependencies`.
* If the value of any of the dependencies fields (`dependencies`, `devDependencies`, `optionalDependencies`) is a string, it gets converted into an object with familiar `name=>value` pairs.
* The values in `optionalDependencies` get added to `dependencies`. The `optionalDependencies` array is left untouched.
* As of v2: Dependencies that point at known hosted git providers (currently: github, bitbucket, gitlab) will have their URLs canonicalized, but protocols will be preserved.
* As of v2: Dependencies that use shortcuts for hosted git providers (`org/proj`, `github:org/proj`, `bitbucket:org/proj`, `gitlab:org/proj`, `gist:docid`) will have the shortcut left in place. (In the case of github, the `org/proj` form will be expanded to `github:org/proj`.) THIS MARKS A BREAKING CHANGE FROM V1, where the shorcut was previously expanded to a URL.
* If `description` field does not exist, but `readme` field does, then (more or less) the first paragraph of text that's found in the readme is taken as value for `description`.
* If `repository` field is a string, it will become an object with `url` set to the original string value, and `type` set to `"git"`.
* If `repository.url` is not a valid url, but in the style of "[owner-name]/[repo-name]", `repository.url` will be set to git+https://github.com/[owner-name]/[repo-name].git
* If `bugs` field is a string, the value of `bugs` field is changed into an object with `url` set to the original string value.
* If `bugs` field does not exist, but `repository` field points to a repository hosted on GitHub, the value of the `bugs` field gets set to an url in the form of https://github.com/[owner-name]/[repo-name]/issues . If the repository field points to a GitHub Gist repo url, the associated http url is chosen.
* If `bugs` field is an object, the resulting value only has email and url properties. If email and url properties are not strings, they are ignored. If no valid values for either email or url is found, bugs field will be removed.
* If `homepage` field is not a string, it will be removed.
* If the url in the `homepage` field does not specify a protocol, then http is assumed. For example, `myproject.org` will be changed to `http://myproject.org`.
* If `homepage` field does not exist, but `repository` field points to a repository hosted on GitHub, the value of the `homepage` field gets set to an url in the form of https://github.com/[owner-name]/[repo-name]#readme . If the repository field points to a GitHub Gist repo url, the associated http url is chosen.
### Rules for name field
If `name` field is given, the value of the name field must be a string. The string may not:
* start with a period.
* contain the following characters: `/@\s+%`
* contain any characters that would need to be encoded for use in urls.
* resemble the word `node_modules` or `favicon.ico` (case doesn't matter).
### Rules for version field
If `version` field is given, the value of the version field must be a valid *semver* string, as determined by the `semver.valid` method. See [documentation for the semver module](https://github.com/isaacs/node-semver).
### Rules for license field
The `license`/`licence` field should be a valid *SPDX license expression* or one of the special values allowed by [validate-npm-package-license](https://npmjs.com/package/validate-npm-package-license). See [documentation for the license field in package.json](https://docs.npmjs.com/files/package.json#license).

<!-- Commented out until they actually show anything
[![npm dependents](https://badgen.net/npm/dependents/type-fest)](https://www.npmjs.com/package/type-fest?activeTab=dependents) [![npm downloads](https://badgen.net/npm/dt/type-fest)](https://www.npmjs.com/package/type-fest)
-->
Many of the types here should have been built-in. You can help by suggesting some of them to the [TypeScript project](https://github.com/Microsoft/TypeScript/blob/master/CONTRIBUTING.md).
Either add this package as a dependency or copy-paste the needed types. No credit required. 👌
PR welcome for additional commonly needed types and docs improvements. Read the [contributing guidelines](.github/contributing.md) first.
## Install
```
$ npm install type-fest
```
*Requires TypeScript >=3.2*
## Usage
```ts
import {Except} from 'type-fest';
type Foo = {
unicorn: string;
rainbow: boolean;
};
type FooWithoutRainbow = Except<Foo, 'rainbow'>;
//=> {unicorn: string}
```
## API
Click the type names for complete docs.
### Basic
- [`Primitive`](source/basic.d.ts) - Matches any [primitive value](https://developer.mozilla.org/en-US/docs/Glossary/Primitive).
- [`Class`](source/basic.d.ts) - Matches a [`class` constructor](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Classes).
- [`TypedArray`](source/basic.d.ts) - Matches any [typed array](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/TypedArray), like `Uint8Array` or `Float64Array`.
- [`JsonObject`](source/basic.d.ts) - Matches a JSON object.
- [`JsonArray`](source/basic.d.ts) - Matches a JSON array.
- [`JsonValue`](source/basic.d.ts) - Matches any valid JSON value.
- [`ObservableLike`](source/basic.d.ts) - Matches a value that is like an [Observable](https://github.com/tc39/proposal-observable).
### Utilities
- [`Except`](source/except.d.ts) - Create a type from an object type without certain keys. This is a stricter version of [`Omit`](https://www.typescriptlang.org/docs/handbook/release-notes/typescript-3-5.html#the-omit-helper-type).
- [`Mutable`](source/mutable.d.ts) - Convert an object with `readonly` keys into a mutable object. The inverse of `Readonly<T>`.
- [`Merge`](source/merge.d.ts) - Merge two types into a new type. Keys of the second type overrides keys of the first type.
- [`MergeExclusive`](source/merge-exclusive.d.ts) - Create a type that has mutually exclusive keys.
- [`RequireAtLeastOne`](source/require-at-least-one.d.ts) - Create a type that requires at least one of the given keys.
- [`RequireExactlyOne`](source/require-one.d.ts) - Create a type that requires exactly a single key of the given keys and disallows more.
- [`PartialDeep`](source/partial-deep.d.ts) - Create a deeply optional version of another type. Use [`Partial<T>`](https://github.com/Microsoft/TypeScript/blob/2961bc3fc0ea1117d4e53bc8e97fa76119bc33e3/src/lib/es5.d.ts#L1401-L1406) if you only need one level deep.
- [`ReadonlyDeep`](source/readonly-deep.d.ts) - Create a deeply immutable version of an `object`/`Map`/`Set`/`Array` type. Use [`Readonly<T>`](https://github.com/Microsoft/TypeScript/blob/2961bc3fc0ea1117d4e53bc8e97fa76119bc33e3/src/lib/es5.d.ts#L1415-L1420) if you only need one level deep.
- [`LiteralUnion`](source/literal-union.d.ts) - Create a union type by combining primitive types and literal types without sacrificing auto-completion in IDEs for the literal type part of the union. Workaround for [Microsoft/TypeScript#29729](https://github.com/Microsoft/TypeScript/issues/29729).
- [`Promisable`](source/promisable.d.ts) - Create a type that represents either the value or the value wrapped in `PromiseLike`.
- [`Opaque`](source/opaque.d.ts) - Create an [opaque type](https://codemix.com/opaque-types-in-javascript/).
- [`SetOptional`](source/set-optional.d.ts) - Create a type that makes the given keys optional.
- [`SetRequired`](source/set-required.d.ts) - Create a type that makes the given keys required.
### Miscellaneous
- [`PackageJson`](source/package-json.d.ts) - Type for [npm's `package.json` file](https://docs.npmjs.com/creating-a-package-json-file).
## Declined types
*If we decline a type addition, we will make sure to document the better solution here.*
- [`Diff` and `Spread`](https://github.com/sindresorhus/type-fest/pull/7) - The PR author didn't provide any real-world use-cases and the PR went stale. If you think this type is useful, provide some real-world use-cases and we might reconsider.
- [`Dictionary`](https://github.com/sindresorhus/type-fest/issues/33) - You only save a few characters (`Dictionary<number>` vs `Record<string, number>`) from [`Record`](https://github.com/Microsoft/TypeScript/blob/2961bc3fc0ea1117d4e53bc8e97fa76119bc33e3/src/lib/es5.d.ts#L1429-L1434), which is more flexible and well-known. Also, you shouldn't use an object as a dictionary. We have `Map` in JavaScript now.
## Tips
### Built-in types
There are many advanced types most users don't know about.
- [`Partial<T>`](https://github.com/Microsoft/TypeScript/blob/2961bc3fc0ea1117d4e53bc8e97fa76119bc33e3/src/lib/es5.d.ts#L1401-L1406) - Make all properties in `T` optional.

Allows creating a union type by combining primitive types and literal types without sacrificing auto-completion in IDEs for the literal type part of the union.

# read-pkg-up [![Build Status](https://travis-ci.org/sindresorhus/read-pkg-up.svg?branch=master)](https://travis-ci.org/sindresorhus/read-pkg-up)
> Read the closest package.json file
## Why
- [Finds the closest package.json](https://github.com/sindresorhus/find-up)
- [Gracefully handles filesystem issues](https://github.com/isaacs/node-graceful-fs)
- [Throws more helpful JSON errors](https://github.com/sindresorhus/parse-json)
- [Normalizes the data](https://github.com/npm/normalize-package-data#what-normalization-currently-entails)
## Install
```
$ npm install read-pkg-up
```
## Usage
```js
const readPkgUp = require('read-pkg-up');
(async () => {
console.log(await readPkgUp());
/*
{
packageJson: {
name: 'awesome-package',
version: '1.0.0',
},
path: '/Users/sindresorhus/dev/awesome-package/package.json'
}
*/
})();
```
## API
### readPkgUp(options?)
Returns a `Promise<object>` or `Promise<undefined>` if no `package.json` was found.
### readPkgUp.sync(options?)
Returns the result object or `undefined` if no `package.json` was found.
#### options
Type: `object`
##### cwd
Type: `string`\
Default: `process.cwd()`
Directory to start looking for a package.json file.
##### normalize
Type: `boolean`\
Default: `true`
[Normalize](https://github.com/npm/normalize-package-data#what-normalization-currently-entails) the package data.

# hosted-git-info
This will let you identify and transform various git hosts URLs between
protocols. It also can tell you what the URL is for the raw path for
particular file for direct access without git.
## Example
```javascript
var hostedGitInfo = require("hosted-git-info")
var info = hostedGitInfo.fromUrl("git@github.com:npm/hosted-git-info.git", opts)
/* info looks like:
{
type: "github",
domain: "github.com",
user: "npm",
project: "hosted-git-info"
}
*/
```
If the URL can't be matched with a git host, `null` will be returned. We
can match git, ssh and https urls. Additionally, we can match ssh connect
strings (`git@github.com:npm/hosted-git-info`) and shortcuts (eg,
`github:npm/hosted-git-info`). Github specifically, is detected in the case
of a third, unprefixed, form: `npm/hosted-git-info`.
If it does match, the returned object has properties of:
* info.type -- The short name of the service
* info.domain -- The domain for git protocol use
* info.user -- The name of the user/org on the git host
* info.project -- The name of the project on the git host
## Version Contract
The major version will be bumped any time…
* The constructor stops accepting URLs that it previously accepted.
* A method is removed.
* A method can no longer accept the number and type of arguments it previously accepted.
* A method can return a different type than it currently returns.
Implications:
* I do not consider the specific format of the urls returned from, say
`.https()` to be a part of the contract. The contract is that it will
return a string that can be used to fetch the repo via HTTPS. But what
that string looks like, specifically, can change.
* Dropping support for a hosted git provider would constitute a breaking
change.
## Usage
### var info = hostedGitInfo.fromUrl(gitSpecifier[, options])
* *gitSpecifer* is a URL of a git repository or a SCP-style specifier of one.
* *options* is an optional object. It can have the following properties:
* *noCommittish* — If true then committishes won't be included in generated URLs.
* *noGitPlus* — If true then `git+` won't be prefixed on URLs.
## Methods
All of the methods take the same options as the `fromUrl` factory. Options
provided to a method override those provided to the constructor.
* info.file(path, opts)
Given the path of a file relative to the repository, returns a URL for
directly fetching it from the githost. If no committish was set then
`master` will be used as the default.
For example `hostedGitInfo.fromUrl("git@github.com:npm/hosted-git-info.git#v1.0.0").file("package.json")`
would return `https://raw.githubusercontent.com/npm/hosted-git-info/v1.0.0/package.json`
* info.shortcut(opts)
eg, `github:npm/hosted-git-info`
* info.browse(path, fragment, opts)
eg, `https://github.com/npm/hosted-git-info/tree/v1.2.0`,
`https://github.com/npm/hosted-git-info/tree/v1.2.0/package.json`,
`https://github.com/npm/hosted-git-info/tree/v1.2.0/REAMDE.md#supported-hosts`
* info.bugs(opts)
eg, `https://github.com/npm/hosted-git-info/issues`
* info.docs(opts)
eg, `https://github.com/npm/hosted-git-info/tree/v1.2.0#readme`
* info.https(opts)
eg, `git+https://github.com/npm/hosted-git-info.git`
* info.sshurl(opts)
eg, `git+ssh://git@github.com/npm/hosted-git-info.git`
* info.ssh(opts)
eg, `git@github.com:npm/hosted-git-info.git`
* info.path(opts)
eg, `npm/hosted-git-info`
* info.tarball(opts)
eg, `https://github.com/npm/hosted-git-info/archive/v1.2.0.tar.gz`
* info.getDefaultRepresentation()
Returns the default output type. The default output type is based on the
string you passed in to be parsed
* info.toString(opts)
Uses the getDefaultRepresentation to call one of the other methods to get a URL for
this resource. As such `hostedGitInfo.fromUrl(url).toString()` will give
you a normalized version of the URL that still uses the same protocol.
Shortcuts will still be returned as shortcuts, but the special case github
form of `org/project` will be normalized to `github:org/project`.
SSH connect strings will be normalized into `git+ssh` URLs.
## Supported hosts
Currently this supports Github, Bitbucket and Gitlab. Pull requests for
additional hosts welcome.

# normalize-package-data [![Build Status](https://travis-ci.org/npm/normalize-package-data.png?branch=master)](https://travis-ci.org/npm/normalize-package-data)
normalize-package-data exports a function that normalizes package metadata. This data is typically found in a package.json file, but in principle could come from any source - for example the npm registry.
normalize-package-data is used by [read-package-json](https://npmjs.org/package/read-package-json) to normalize the data it reads from a package.json file. In turn, read-package-json is used by [npm](https://npmjs.org/package/npm) and various npm-related tools.
## Installation
```
npm install normalize-package-data
```
## Usage
Basic usage is really simple. You call the function that normalize-package-data exports. Let's call it `normalizeData`.
```javascript
normalizeData = require('normalize-package-data')
packageData = require("./package.json")
normalizeData(packageData)
// packageData is now normalized
```
#### Strict mode
You may activate strict validation by passing true as the second argument.
```javascript
normalizeData = require('normalize-package-data')
packageData = require("./package.json")
normalizeData(packageData, true)
// packageData is now normalized
```
If strict mode is activated, only Semver 2.0 version strings are accepted. Otherwise, Semver 1.0 strings are accepted as well. Packages must have a name, and the name field must not have contain leading or trailing whitespace.
#### Warnings
Optionally, you may pass a "warning" function. It gets called whenever the `normalizeData` function encounters something that doesn't look right. It indicates less than perfect input data.
```javascript
normalizeData = require('normalize-package-data')
packageData = require("./package.json")
warnFn = function(msg) { console.error(msg) }
normalizeData(packageData, warnFn)
// packageData is now normalized. Any number of warnings may have been logged.
```
You may combine strict validation with warnings by passing `true` as the second argument, and `warnFn` as third.
When `private` field is set to `true`, warnings will be suppressed.
### Potential exceptions
If the supplied data has an invalid name or version vield, `normalizeData` will throw an error. Depending on where you call `normalizeData`, you may want to catch these errors so can pass them to a callback.
## What normalization (currently) entails
* The value of `name` field gets trimmed (unless in strict mode).
* The value of the `version` field gets cleaned by `semver.clean`. See [documentation for the semver module](https://github.com/isaacs/node-semver).
* If `name` and/or `version` fields are missing, they are set to empty strings.
* If `files` field is not an array, it will be removed.
* If `bin` field is a string, then `bin` field will become an object with `name` set to the value of the `name` field, and `bin` set to the original string value.
* If `man` field is a string, it will become an array with the original string as its sole member.
* If `keywords` field is string, it is considered to be a list of keywords separated by one or more white-space characters. It gets converted to an array by splitting on `\s+`.
* All people fields (`author`, `maintainers`, `contributors`) get converted into objects with name, email and url properties.
* If `bundledDependencies` field (a typo) exists and `bundleDependencies` field does not, `bundledDependencies` will get renamed to `bundleDependencies`.
* If the value of any of the dependencies fields (`dependencies`, `devDependencies`, `optionalDependencies`) is a string, it gets converted into an object with familiar `name=>value` pairs.
* The values in `optionalDependencies` get added to `dependencies`. The `optionalDependencies` array is left untouched.
* As of v2: Dependencies that point at known hosted git providers (currently: github, bitbucket, gitlab) will have their URLs canonicalized, but protocols will be preserved.
* As of v2: Dependencies that use shortcuts for hosted git providers (`org/proj`, `github:org/proj`, `bitbucket:org/proj`, `gitlab:org/proj`, `gist:docid`) will have the shortcut left in place. (In the case of github, the `org/proj` form will be expanded to `github:org/proj`.) THIS MARKS A BREAKING CHANGE FROM V1, where the shorcut was previously expanded to a URL.
* If `description` field does not exist, but `readme` field does, then (more or less) the first paragraph of text that's found in the readme is taken as value for `description`.
* If `repository` field is a string, it will become an object with `url` set to the original string value, and `type` set to `"git"`.
* If `repository.url` is not a valid url, but in the style of "[owner-name]/[repo-name]", `repository.url` will be set to git+https://github.com/[owner-name]/[repo-name].git
* If `bugs` field is a string, the value of `bugs` field is changed into an object with `url` set to the original string value.
* If `bugs` field does not exist, but `repository` field points to a repository hosted on GitHub, the value of the `bugs` field gets set to an url in the form of https://github.com/[owner-name]/[repo-name]/issues . If the repository field points to a GitHub Gist repo url, the associated http url is chosen.
* If `bugs` field is an object, the resulting value only has email and url properties. If email and url properties are not strings, they are ignored. If no valid values for either email or url is found, bugs field will be removed.
* If `homepage` field is not a string, it will be removed.
* If the url in the `homepage` field does not specify a protocol, then http is assumed. For example, `myproject.org` will be changed to `http://myproject.org`.
* If `homepage` field does not exist, but `repository` field points to a repository hosted on GitHub, the value of the `homepage` field gets set to an url in the form of https://github.com/[owner-name]/[repo-name]#readme . If the repository field points to a GitHub Gist repo url, the associated http url is chosen.
### Rules for name field
If `name` field is given, the value of the name field must be a string. The string may not:
* start with a period.
* contain the following characters: `/@\s+%`
* contain any characters that would need to be encoded for use in urls.
* resemble the word `node_modules` or `favicon.ico` (case doesn't matter).
### Rules for version field
If `version` field is given, the value of the version field must be a valid *semver* string, as determined by the `semver.valid` method. See [documentation for the semver module](https://github.com/isaacs/node-semver).
### Rules for license field
The `license` field should be a valid *SPDX license expression* or one of the special values allowed by [validate-npm-package-license](https://npmjs.com/package/validate-npm-package-license). See [documentation for the license field in package.json](https://docs.npmjs.com/files/package.json#license).

semver(1) -- The semantic versioner for npm
===========================================
## Install
```bash
npm install --save semver
````
## Usage
As a node module:
```js
const semver = require('semver')
semver.valid('1.2.3') // '1.2.3'
semver.valid('a.b.c') // null
semver.clean(' =v1.2.3 ') // '1.2.3'
semver.satisfies('1.2.3', '1.x || >=2.5.0 || 5.0.0 - 7.2.3') // true
semver.gt('1.2.3', '9.8.7') // false
semver.lt('1.2.3', '9.8.7') // true
semver.minVersion('>=1.0.0') // '1.0.0'
semver.valid(semver.coerce('v2')) // '2.0.0'
semver.valid(semver.coerce('42.6.7.9.3-alpha')) // '42.6.7'
```
As a command-line utility:
```
$ semver -h
A JavaScript implementation of the https://semver.org/ specification
Copyright Isaac Z. Schlueter
Usage: semver [options] <version> [<version> [...]]
Prints valid versions sorted by SemVer precedence
Options:
-r --range <range>
Print versions that match the specified range.
-i --increment [<level>]
Increment a version by the specified level. Level can
be one of: major, minor, patch, premajor, preminor,
prepatch, or prerelease. Default level is 'patch'.
Only one version may be specified.
--preid <identifier>
Identifier to be used to prefix premajor, preminor,
prepatch or prerelease version increments.
-l --loose
Interpret versions and ranges loosely
-p --include-prerelease
Always include prerelease versions in range matching
-c --coerce
Coerce a string into SemVer if possible
(does not imply --loose)
Program exits successfully if any valid version satisfies
all supplied ranges, and prints all satisfying versions.
If no satisfying versions are found, then exits failure.
Versions are printed in ascending order, so supplying
multiple versions to the utility will just sort them.
```
## Versions
A "version" is described by the `v2.0.0` specification found at
<https://semver.org/>.
A leading `"="` or `"v"` character is stripped off and ignored.
## Ranges
A `version range` is a set of `comparators` which specify versions
that satisfy the range.
A `comparator` is composed of an `operator` and a `version`. The set
of primitive `operators` is:
* `<` Less than
* `<=` Less than or equal to
* `>` Greater than
* `>=` Greater than or equal to
* `=` Equal. If no operator is specified, then equality is assumed,
so this operator is optional, but MAY be included.
For example, the comparator `>=1.2.7` would match the versions
`1.2.7`, `1.2.8`, `2.5.3`, and `1.3.9`, but not the versions `1.2.6`
or `1.1.0`.
Comparators can be joined by whitespace to form a `comparator set`,
which is satisfied by the **intersection** of all of the comparators
it includes.
A range is composed of one or more comparator sets, joined by `||`. A
version matches a range if and only if every comparator in at least
one of the `||`-separated comparator sets is satisfied by the version.
For example, the range `>=1.2.7 <1.3.0` would match the versions
`1.2.7`, `1.2.8`, and `1.2.99`, but not the versions `1.2.6`, `1.3.0`,
or `1.1.0`.
The range `1.2.7 || >=1.2.9 <2.0.0` would match the versions `1.2.7`,
`1.2.9`, and `1.4.6`, but not the versions `1.2.8` or `2.0.0`.
### Prerelease Tags
If a version has a prerelease tag (for example, `1.2.3-alpha.3`) then
it will only be allowed to satisfy comparator sets if at least one
comparator with the same `[major, minor, patch]` tuple also has a
prerelease tag.
For example, the range `>1.2.3-alpha.3` would be allowed to match the
version `1.2.3-alpha.7`, but it would *not* be satisfied by
`3.4.5-alpha.9`, even though `3.4.5-alpha.9` is technically "greater
than" `1.2.3-alpha.3` according to the SemVer sort rules. The version
range only accepts prerelease tags on the `1.2.3` version. The
version `3.4.5` *would* satisfy the range, because it does not have a
prerelease flag, and `3.4.5` is greater than `1.2.3-alpha.7`.
The purpose for this behavior is twofold. First, prerelease versions
frequently are updated very quickly, and contain many breaking changes
that are (by the author's design) not yet fit for public consumption.
Therefore, by default, they are excluded from range matching
semantics.
Second, a user who has opted into using a prerelease version has
clearly indicated the intent to use *that specific* set of
alpha/beta/rc versions. By including a prerelease tag in the range,
the user is indicating that they are aware of the risk. However, it
is still not appropriate to assume that they have opted into taking a
similar risk on the *next* set of prerelease versions.
Note that this behavior can be suppressed (treating all prerelease
versions as if they were normal versions, for the purpose of range
matching) by setting the `includePrerelease` flag on the options
object to any
[functions](https://github.com/npm/node-semver#functions) that do
range matching.
#### Prerelease Identifiers
The method `.inc` takes an additional `identifier` string argument that
will append the value of the string as a prerelease identifier:
```javascript
semver.inc('1.2.3', 'prerelease', 'beta')
// '1.2.4-beta.0'
```
command-line example:
```bash
$ semver 1.2.3 -i prerelease --preid beta
1.2.4-beta.0
```
Which then can be used to increment further:
```bash
$ semver 1.2.4-beta.0 -i prerelease
1.2.4-beta.1
```
### Advanced Range Syntax
Advanced range syntax desugars to primitive comparators in
deterministic ways.
Advanced ranges may be combined in the same way as primitive
comparators using white space or `||`.
#### Hyphen Ranges `X.Y.Z - A.B.C`
Specifies an inclusive set.
* `1.2.3 - 2.3.4` := `>=1.2.3 <=2.3.4`
If a partial version is provided as the first version in the inclusive
range, then the missing pieces are replaced with zeroes.
* `1.2 - 2.3.4` := `>=1.2.0 <=2.3.4`
If a partial version is provided as the second version in the
inclusive range, then all versions that start with the supplied parts
of the tuple are accepted, but nothing that would be greater than the
provided tuple parts.
* `1.2.3 - 2.3` := `>=1.2.3 <2.4.0`
* `1.2.3 - 2` := `>=1.2.3 <3.0.0`
#### X-Ranges `1.2.x` `1.X` `1.2.*` `*`
Any of `X`, `x`, or `*` may be used to "stand in" for one of the
numeric values in the `[major, minor, patch]` tuple.
* `*` := `>=0.0.0` (Any version satisfies)
* `1.x` := `>=1.0.0 <2.0.0` (Matching major version)
* `1.2.x` := `>=1.2.0 <1.3.0` (Matching major and minor versions)
A partial version range is treated as an X-Range, so the special
character is in fact optional.
* `""` (empty string) := `*` := `>=0.0.0`
* `1` := `1.x.x` := `>=1.0.0 <2.0.0`
* `1.2` := `1.2.x` := `>=1.2.0 <1.3.0`
#### Tilde Ranges `~1.2.3` `~1.2` `~1`
Allows patch-level changes if a minor version is specified on the
comparator. Allows minor-level changes if not.
* `~1.2.3` := `>=1.2.3 <1.(2+1).0` := `>=1.2.3 <1.3.0`
* `~1.2` := `>=1.2.0 <1.(2+1).0` := `>=1.2.0 <1.3.0` (Same as `1.2.x`)
* `~1` := `>=1.0.0 <(1+1).0.0` := `>=1.0.0 <2.0.0` (Same as `1.x`)
* `~0.2.3` := `>=0.2.3 <0.(2+1).0` := `>=0.2.3 <0.3.0`
* `~0.2` := `>=0.2.0 <0.(2+1).0` := `>=0.2.0 <0.3.0` (Same as `0.2.x`)
* `~0` := `>=0.0.0 <(0+1).0.0` := `>=0.0.0 <1.0.0` (Same as `0.x`)
* `~1.2.3-beta.2` := `>=1.2.3-beta.2 <1.3.0` Note that prereleases in
the `1.2.3` version will be allowed, if they are greater than or
equal to `beta.2`. So, `1.2.3-beta.4` would be allowed, but
`1.2.4-beta.2` would not, because it is a prerelease of a
different `[major, minor, patch]` tuple.
#### Caret Ranges `^1.2.3` `^0.2.5` `^0.0.4`
Allows changes that do not modify the left-most non-zero digit in the
`[major, minor, patch]` tuple. In other words, this allows patch and
minor updates for versions `1.0.0` and above, patch updates for
versions `0.X >=0.1.0`, and *no* updates for versions `0.0.X`.
Many authors treat a `0.x` version as if the `x` were the major
"breaking-change" indicator.
Caret ranges are ideal when an author may make breaking changes
between `0.2.4` and `0.3.0` releases, which is a common practice.
However, it presumes that there will *not* be breaking changes between
`0.2.4` and `0.2.5`. It allows for changes that are presumed to be
additive (but non-breaking), according to commonly observed practices.
* `^1.2.3` := `>=1.2.3 <2.0.0`
* `^0.2.3` := `>=0.2.3 <0.3.0`
* `^0.0.3` := `>=0.0.3 <0.0.4`
* `^1.2.3-beta.2` := `>=1.2.3-beta.2 <2.0.0` Note that prereleases in
the `1.2.3` version will be allowed, if they are greater than or
equal to `beta.2`. So, `1.2.3-beta.4` would be allowed, but
`1.2.4-beta.2` would not, because it is a prerelease of a
different `[major, minor, patch]` tuple.
* `^0.0.3-beta` := `>=0.0.3-beta <0.0.4` Note that prereleases in the
`0.0.3` version *only* will be allowed, if they are greater than or
equal to `beta`. So, `0.0.3-pr.2` would be allowed.
When parsing caret ranges, a missing `patch` value desugars to the
number `0`, but will allow flexibility within that value, even if the
major and minor versions are both `0`.
* `^1.2.x` := `>=1.2.0 <2.0.0`
* `^0.0.x` := `>=0.0.0 <0.1.0`
* `^0.0` := `>=0.0.0 <0.1.0`
A missing `minor` and `patch` values will desugar to zero, but also
allow flexibility within those values, even if the major version is
zero.
* `^1.x` := `>=1.0.0 <2.0.0`
* `^0.x` := `>=0.0.0 <1.0.0`
### Range Grammar
Putting all this together, here is a Backus-Naur grammar for ranges,
for the benefit of parser authors:
```bnf
range-set ::= range ( logical-or range ) *
logical-or ::= ( ' ' ) * '||' ( ' ' ) *
range ::= hyphen | simple ( ' ' simple ) * | ''
hyphen ::= partial ' - ' partial
simple ::= primitive | partial | tilde | caret
primitive ::= ( '<' | '>' | '>=' | '<=' | '=' ) partial
partial ::= xr ( '.' xr ( '.' xr qualifier ? )? )?
xr ::= 'x' | 'X' | '*' | nr
nr ::= '0' | ['1'-'9'] ( ['0'-'9'] ) *
tilde ::= '~' partial
caret ::= '^' partial
qualifier ::= ( '-' pre )? ( '+' build )?
pre ::= parts
build ::= parts
parts ::= part ( '.' part ) *
part ::= nr | [-0-9A-Za-z]+
```
## Functions
All methods and classes take a final `options` object argument. All
options in this object are `false` by default. The options supported
are:
- `loose` Be more forgiving about not-quite-valid semver strings.
(Any resulting output will always be 100% strict compliant, of
course.) For backwards compatibility reasons, if the `options`
argument is a boolean value instead of an object, it is interpreted
to be the `loose` param.
- `includePrerelease` Set to suppress the [default
behavior](https://github.com/npm/node-semver#prerelease-tags) of
excluding prerelease tagged versions from ranges unless they are
explicitly opted into.
Strict-mode Comparators and Ranges will be strict about the SemVer
strings that they parse.
* `valid(v)`: Return the parsed version, or null if it's not valid.
* `inc(v, release)`: Return the version incremented by the release
type (`major`, `premajor`, `minor`, `preminor`, `patch`,
`prepatch`, or `prerelease`), or null if it's not valid
* `premajor` in one call will bump the version up to the next major
version and down to a prerelease of that major version.
`preminor`, and `prepatch` work the same way.
* If called from a non-prerelease version, the `prerelease` will work the
same as `prepatch`. It increments the patch version, then makes a
prerelease. If the input version is already a prerelease it simply
increments it.
* `prerelease(v)`: Returns an array of prerelease components, or null
if none exist. Example: `prerelease('1.2.3-alpha.1') -> ['alpha', 1]`
* `major(v)`: Return the major version number.
* `minor(v)`: Return the minor version number.
* `patch(v)`: Return the patch version number.
* `intersects(r1, r2, loose)`: Return true if the two supplied ranges
or comparators intersect.
* `parse(v)`: Attempt to parse a string as a semantic version, returning either
a `SemVer` object or `null`.
### Comparison
* `gt(v1, v2)`: `v1 > v2`
* `gte(v1, v2)`: `v1 >= v2`
* `lt(v1, v2)`: `v1 < v2`
* `lte(v1, v2)`: `v1 <= v2`
* `eq(v1, v2)`: `v1 == v2` This is true if they're logically equivalent,
even if they're not the exact same string. You already know how to
compare strings.
* `neq(v1, v2)`: `v1 != v2` The opposite of `eq`.
* `cmp(v1, comparator, v2)`: Pass in a comparison string, and it'll call
the corresponding function above. `"==="` and `"!=="` do simple
string comparison, but are included for completeness. Throws if an
invalid comparison string is provided.
* `compare(v1, v2)`: Return `0` if `v1 == v2`, or `1` if `v1` is greater, or `-1` if
`v2` is greater. Sorts in ascending order if passed to `Array.sort()`.
* `rcompare(v1, v2)`: The reverse of compare. Sorts an array of versions
in descending order when passed to `Array.sort()`.
* `diff(v1, v2)`: Returns difference between two versions by the release type
(`major`, `premajor`, `minor`, `preminor`, `patch`, `prepatch`, or `prerelease`),
or null if the versions are the same.
### Comparators
* `intersects(comparator)`: Return true if the comparators intersect
### Ranges
* `validRange(range)`: Return the valid range or null if it's not valid
* `satisfies(version, range)`: Return true if the version satisfies the
range.
* `maxSatisfying(versions, range)`: Return the highest version in the list
that satisfies the range, or `null` if none of them do.
* `minSatisfying(versions, range)`: Return the lowest version in the list
that satisfies the range, or `null` if none of them do.
* `minVersion(range)`: Return the lowest version that can possibly match
the given range.
* `gtr(version, range)`: Return `true` if version is greater than all the
versions possible in the range.
* `ltr(version, range)`: Return `true` if version is less than all the
versions possible in the range.
* `outside(version, range, hilo)`: Return true if the version is outside
the bounds of the range in either the high or low direction. The
`hilo` argument must be either the string `'>'` or `'<'`. (This is
the function called by `gtr` and `ltr`.)
* `intersects(range)`: Return true if any of the ranges comparators intersect
Note that, since ranges may be non-contiguous, a version might not be
greater than a range, less than a range, *or* satisfy a range! For
example, the range `1.2 <1.2.9 || >2.0.0` would have a hole from `1.2.9`
until `2.0.0`, so the version `1.2.10` would not be greater than the
range (because `2.0.1` satisfies, which is higher), nor less than the
range (since `1.2.8` satisfies, which is lower), and it also does not
satisfy the range.
If you want to know if a version satisfies or does not satisfy a
range, use the `satisfies(version, range)` function.
### Coercion
* `coerce(version)`: Coerces a string to semver if possible
This aims to provide a very forgiving translation of a non-semver string to
semver. It looks for the first digit in a string, and consumes all
remaining characters which satisfy at least a partial semver (e.g., `1`,
`1.2`, `1.2.3`) up to the max permitted length (256 characters). Longer
versions are simply truncated (`4.6.3.9.2-alpha2` becomes `4.6.3`). All
surrounding text is simply ignored (`v3.4 replaces v3.3.1` becomes
`3.4.0`). Only text which lacks digits will fail coercion (`version one`
is not valid). The maximum length for any semver component considered for
coercion is 16 characters; longer components will be ignored
(`10000000000000000.4.7.4` becomes `4.7.4`). The maximum value for any
semver component is `Number.MAX_SAFE_INTEGER || (2**53 - 1)`; higher value
components are invalid (`9999999999999999.4.7.4` is likely invalid).

Many of the types here should have been built-in. You can help by suggesting some of them to the [TypeScript project](https://github.com/Microsoft/TypeScript/blob/master/CONTRIBUTING.md).
Either add this package as a dependency or copy-paste the needed types. No credit required. 👌
PR welcome for additional commonly needed types and docs improvements. Read the [contributing guidelines](.github/contributing.md) first.
## Install
```
$ npm install type-fest
```
*Requires TypeScript >=3.2*
## Usage
```ts
import {Except} from 'type-fest';
type Foo = {
unicorn: string;
rainbow: boolean;
};
type FooWithoutRainbow = Except<Foo, 'rainbow'>;
//=> {unicorn: string}
```
## API
Click the type names for complete docs.
### Basic
- [`Primitive`](source/basic.d.ts) - Matches any [primitive value](https://developer.mozilla.org/en-US/docs/Glossary/Primitive).
- [`Class`](source/basic.d.ts) - Matches a [`class` constructor](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Classes).
- [`TypedArray`](source/basic.d.ts) - Matches any [typed array](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/TypedArray), like `Uint8Array` or `Float64Array`.
- [`JsonObject`](source/basic.d.ts) - Matches a JSON object.
- [`JsonArray`](source/basic.d.ts) - Matches a JSON array.
- [`JsonValue`](source/basic.d.ts) - Matches any valid JSON value.
- [`ObservableLike`](source/basic.d.ts) - Matches a value that is like an [Observable](https://github.com/tc39/proposal-observable).
### Utilities
- [`Except`](source/except.d.ts) - Create a type from an object type without certain keys. This is a stricter version of [`Omit`](https://www.typescriptlang.org/docs/handbook/release-notes/typescript-3-5.html#the-omit-helper-type).
- [`Mutable`](source/mutable.d.ts) - Convert an object with `readonly` properties into a mutable object. Inverse of `Readonly<T>`.
- [`Merge`](source/merge.d.ts) - Merge two types into a new type. Keys of the second type overrides keys of the first type.
- [`MergeExclusive`](source/merge-exclusive.d.ts) - Create a type that has mutually exclusive properties.
- [`RequireAtLeastOne`](source/require-at-least-one.d.ts) - Create a type that requires at least one of the given properties.
- [`ReadonlyDeep`](source/readonly-deep.d.ts) - Create a deeply immutable version of a `object`/`Map`/`Set`/`Array` type.
- [`LiteralUnion`](source/literal-union.d.ts) - Create a union type by combining primitive types and literal types without sacrificing auto-completion in IDEs for the literal type part of the union. Workaround for [Microsoft/TypeScript#29729](https://github.com/Microsoft/TypeScript/issues/29729).
- [`Promisable`](source/promisable.d.ts) - Create a type that represents either the value or the value wrapped in `PromiseLike`.
### Miscellaneous
- [`PackageJson`](source/package-json.d.ts) - Type for [npm's `package.json` file](https://docs.npmjs.com/creating-a-package-json-file).
## Declined types
*If we decline a type addition, we will make sure to document the better solution here.*
- [`Diff` and `Spread`](https://github.com/sindresorhus/type-fest/pull/7) - The PR author didn't provide any real-world use-cases and the PR went stale. If you think this type is useful, provide some real-world use-cases and we might reconsider.
## Tips
### Built-in types
There are many advanced types most users don't know about.
- [`Partial<T>`](https://github.com/Microsoft/TypeScript/blob/2961bc3fc0ea1117d4e53bc8e97fa76119bc33e3/src/lib/es5.d.ts#L1401-L1406) - Make all properties in `T` optional.
- [`Required<T>`](https://github.com/Microsoft/TypeScript/blob/2961bc3fc0ea1117d4e53bc8e97fa76119bc33e3/src/lib/es5.d.ts#L1408-L1413) - Make all properties in `T` required.
- [`Readonly<T>`](https://github.com/Microsoft/TypeScript/blob/2961bc3fc0ea1117d4e53bc8e97fa76119bc33e3/src/lib/es5.d.ts#L1415-L1420) - Make all properties in `T` readonly.
- [`Pick<T, K>`](https://github.com/Microsoft/TypeScript/blob/2961bc3fc0ea1117d4e53bc8e97fa76119bc33e3/src/lib/es5.d.ts#L1422-L1427) - From `T`, pick a set of properties whose keys are in the union `K`.
- [`Record<K, T>`](https://github.com/Microsoft/TypeScript/blob/2961bc3fc0ea1117d4e53bc8e97fa76119bc33e3/src/lib/es5.d.ts#L1429-L1434) - Construct a type with a set of properties `K` of type `T`.
- [`Exclude<T, U>`](https://github.com/Microsoft/TypeScript/blob/2961bc3fc0ea1117d4e53bc8e97fa76119bc33e3/src/lib/es5.d.ts#L1436-L1439) - Exclude from `T` those types that are assignable to `U`.
- [`Extract<T, U>`](https://github.com/Microsoft/TypeScript/blob/2961bc3fc0ea1117d4e53bc8e97fa76119bc33e3/src/lib/es5.d.ts#L1441-L1444) - Extract from `T` those types that are assignable to `U`.
- [`NonNullable<T>`](https://github.com/Microsoft/TypeScript/blob/2961bc3fc0ea1117d4e53bc8e97fa76119bc33e3/src/lib/es5.d.ts#L1446-L1449) - Exclude `null` and `undefined` from `T`.
- [`Parameters<T>`](https://github.com/Microsoft/TypeScript/blob/2961bc3fc0ea1117d4e53bc8e97fa76119bc33e3/src/lib/es5.d.ts#L1451-L1454) - Obtain the parameters of a function type in a tuple.
- [`ConstructorParameters<T>`](https://github.com/Microsoft/TypeScript/blob/2961bc3fc0ea1117d4e53bc8e97fa76119bc33e3/src/lib/es5.d.ts#L1456-L1459) - Obtain the parameters of a constructor function type in a tuple.
- [`ReturnType<T>`](https://github.com/Microsoft/TypeScript/blob/2961bc3fc0ea1117d4e53bc8e97fa76119bc33e3/src/lib/es5.d.ts#L1461-L1464) Obtain the return type of a function type.
- [`InstanceType<T>`](https://github.com/Microsoft/TypeScript/blob/2961bc3fc0ea1117d4e53bc8e97fa76119bc33e3/src/lib/es5.d.ts#L1466-L1469) Obtain the instance type of a constructor function type.

The benefits of a stricter type are avoiding typos and allowing the compiler to pick up on rename refactors automatically.

Allows creating a union type by combining primitive types and literal types without sacrificing auto-completion in IDEs for the literal type part of the union.
Currently, when a union type of a primitive type is combined with literal types, TypeScript loses all information about the combined literals. Thus, when such type is used in an IDE with autocompletion, no suggestions are made for the declared literals.
This type is a workaround for [Microsoft/TypeScript#29729](https://github.com/Microsoft/TypeScript/issues/29729). It will be removed as soon as it's not needed anymore.

This type works with a helper type, called `Without`. `Without<FirstType, SecondType>` produces a type that has only keys from `FirstType` which are not present on `SecondType` and sets the value type for these keys to `never`. This helper type is then used in `MergeExclusive` to remove keys from either `FirstType` or `SecondType`.

# read-pkg [![Build Status](https://travis-ci.org/sindresorhus/read-pkg.svg?branch=master)](https://travis-ci.org/sindresorhus/read-pkg)
> Read a package.json file
## Why
- [Gracefully handles filesystem issues](https://github.com/isaacs/node-graceful-fs)
- [Throws more helpful JSON errors](https://github.com/sindresorhus/parse-json)
- [Normalizes the data](https://github.com/npm/normalize-package-data#what-normalization-currently-entails)
## Install
```
$ npm install read-pkg
```
## Usage
```js
const readPkg = require('read-pkg');
(async () => {
console.log(await readPkg());
//=> {name: 'read-pkg', …}
console.log(await readPkg({cwd: 'some-other-directory'}));
//=> {name: 'unicorn', …}
})();
```
## API
### readPkg(options?)
Returns a `Promise<object>` with the parsed JSON.
### readPkg.sync(options?)
Returns the parsed JSON.
#### options
Type: `object`
##### cwd
Type: `string`<br>
Default: `process.cwd()`
Current working directory.
##### normalize
Type: `boolean`<br>
Default: `true`
[Normalize](https://github.com/npm/normalize-package-data#what-normalization-currently-entails) the package data.

# changes log
## 7.3.0
* Add `subset(r1, r2)` method to determine if `r1` range is entirely
contained by `r2` range.
## 7.2.3
* Fix handling of `includePrelease` mode where version ranges like `1.0.0 -
2.0.0` would include `3.0.0-pre` and not `1.0.0-pre`.
## 7.2.2
* Fix bug where `2.0.0-pre` would be included in `^1.0.0` if
`includePrerelease` was set to true.
## 7.2.0
* Add `simplifyRange` method to attempt to generate a more human-readable
range expression that is equivalent to a supplied range, for a given set
of versions.
## 7.1.2
* Remove fancy lazy-loading logic, as it was causing problems for webpack
users.
## 7.1.0
* Add `require('semver/preload')` to load the entire module without using
lazy getter methods.
## 7.0.0
* Refactor module into separate files for better tree-shaking
* Drop support for very old node versions, use const/let, `=>` functions,
and classes.
## 6.3.0
* Expose the token enum on the exports
## 6.2.0
* Coerce numbers to strings when passed to semver.coerce()
* Add `rtl` option to coerce from right to left
## 6.1.3
* Handle X-ranges properly in includePrerelease mode
## 6.1.2
* Do not throw when testing invalid version strings
## 6.1.1
* Add options support for semver.coerce()
* Handle undefined version passed to Range.test
## 6.1.0
* Add semver.compareBuild function
* Support `*` in semver.intersects
## 6.0
* Fix `intersects` logic.
This is technically a bug fix, but since it is also a change to behavior
that may require users updating their code, it is marked as a major
version increment.
## 5.7
* Add `minVersion` method
## 5.6
* Move boolean `loose` param to an options object, with
backwards-compatibility protection.
* Add ability to opt out of special prerelease version handling with
the `includePrerelease` option flag.
## 5.5
* Add version coercion capabilities
## 5.4
* Add intersection checking
## 5.3
* Add `minSatisfying` method
## 5.2
* Add `prerelease(v)` that returns prerelease components
## 5.1
* Add Backus-Naur for ranges
* Remove excessively cute inspection methods
## 5.0
* Remove AMD/Browserified build artifacts
* Fix ltr and gtr when using the `*` range
* Fix for range `*` with a prerelease identifier

semver(1) -- The semantic versioner for npm
===========================================
## Install
```bash
npm install semver
````
## Usage
As a node module:
```js
const semver = require('semver')
semver.valid('1.2.3') // '1.2.3'
semver.valid('a.b.c') // null
semver.clean(' =v1.2.3 ') // '1.2.3'
semver.satisfies('1.2.3', '1.x || >=2.5.0 || 5.0.0 - 7.2.3') // true
semver.gt('1.2.3', '9.8.7') // false
semver.lt('1.2.3', '9.8.7') // true
semver.minVersion('>=1.0.0') // '1.0.0'
semver.valid(semver.coerce('v2')) // '2.0.0'
semver.valid(semver.coerce('42.6.7.9.3-alpha')) // '42.6.7'
```
You can also just load the module for the function that you care about, if
you'd like to minimize your footprint.
```js
// load the whole API at once in a single object
const semver = require('semver')
// or just load the bits you need
// all of them listed here, just pick and choose what you want
// classes
const SemVer = require('semver/classes/semver')
const Comparator = require('semver/classes/comparator')
const Range = require('semver/classes/range')
// functions for working with versions
const semverParse = require('semver/functions/parse')
const semverValid = require('semver/functions/valid')

const semverInc = require('semver/functions/inc')
const semverDiff = require('semver/functions/diff')
const semverMajor = require('semver/functions/major')

const semverCompareBuild = require('semver/functions/compare-build')
const semverSort = require('semver/functions/sort')
const semverRsort = require('semver/functions/rsort')
// low-level comparators between versions
const semverGt = require('semver/functions/gt')
const semverLt = require('semver/functions/lt')
const semverEq = require('semver/functions/eq')
const semverNeq = require('semver/functions/neq')
const semverGte = require('semver/functions/gte')
const semverLte = require('semver/functions/lte')
const semverCmp = require('semver/functions/cmp')
const semverCoerce = require('semver/functions/coerce')
// working with ranges
const semverSatisfies = require('semver/functions/satisfies')
const semverMaxSatisfying = require('semver/ranges/max-satisfying')
const semverMinSatisfying = require('semver/ranges/min-satisfying')
const semverToComparators = require('semver/ranges/to-comparators')
const semverMinVersion = require('semver/ranges/min-version')
const semverValidRange = require('semver/ranges/valid')
const semverOutside = require('semver/ranges/outside')
const semverGtr = require('semver/ranges/gtr')
const semverLtr = require('semver/ranges/ltr')
const semverIntersects = require('semver/ranges/intersects')
const simplifyRange = require('semver/ranges/simplify')
const rangeSubset = require('semver/ranges/subset')
```
As a command-line utility:
```
$ semver -h
A JavaScript implementation of the https://semver.org/ specification
Copyright Isaac Z. Schlueter
Usage: semver [options] <version> [<version> [...]]
Prints valid versions sorted by SemVer precedence
Options:
-r --range <range>
Print versions that match the specified range.
-i --increment [<level>]
Increment a version by the specified level. Level can
be one of: major, minor, patch, premajor, preminor,
prepatch, or prerelease. Default level is 'patch'.

```
## Versions
A "version" is described by the `v2.0.0` specification found at
<https://semver.org/>.
A leading `"="` or `"v"` character is stripped off and ignored.
## Ranges
A `version range` is a set of `comparators` which specify versions
that satisfy the range.
A `comparator` is composed of an `operator` and a `version`. The set
of primitive `operators` is:
* `<` Less than
* `<=` Less than or equal to
* `>` Greater than
* `>=` Greater than or equal to
* `=` Equal. If no operator is specified, then equality is assumed,
so this operator is optional, but MAY be included.
For example, the comparator `>=1.2.7` would match the versions
`1.2.7`, `1.2.8`, `2.5.3`, and `1.3.9`, but not the versions `1.2.6`
or `1.1.0`.
Comparators can be joined by whitespace to form a `comparator set`,
which is satisfied by the **intersection** of all of the comparators
it includes.
A range is composed of one or more comparator sets, joined by `||`. A
version matches a range if and only if every comparator in at least
one of the `||`-separated comparator sets is satisfied by the version.
For example, the range `>=1.2.7 <1.3.0` would match the versions
`1.2.7`, `1.2.8`, and `1.2.99`, but not the versions `1.2.6`, `1.3.0`,
or `1.1.0`.
The range `1.2.7 || >=1.2.9 <2.0.0` would match the versions `1.2.7`,
`1.2.9`, and `1.4.6`, but not the versions `1.2.8` or `2.0.0`.
### Prerelease Tags
If a version has a prerelease tag (for example, `1.2.3-alpha.3`) then
it will only be allowed to satisfy comparator sets if at least one
comparator with the same `[major, minor, patch]` tuple also has a
prerelease tag.
For example, the range `>1.2.3-alpha.3` would be allowed to match the
version `1.2.3-alpha.7`, but it would *not* be satisfied by
`3.4.5-alpha.9`, even though `3.4.5-alpha.9` is technically "greater
than" `1.2.3-alpha.3` according to the SemVer sort rules. The version
range only accepts prerelease tags on the `1.2.3` version. The
version `3.4.5` *would* satisfy the range, because it does not have a
prerelease flag, and `3.4.5` is greater than `1.2.3-alpha.7`.
The purpose for this behavior is twofold. First, prerelease versions
frequently are updated very quickly, and contain many breaking changes
that are (by the author's design) not yet fit for public consumption.
Therefore, by default, they are excluded from range matching
semantics.
Second, a user who has opted into using a prerelease version has
clearly indicated the intent to use *that specific* set of
alpha/beta/rc versions. By including a prerelease tag in the range,
the user is indicating that they are aware of the risk. However, it
is still not appropriate to assume that they have opted into taking a
similar risk on the *next* set of prerelease versions.
Note that this behavior can be suppressed (treating all prerelease
versions as if they were normal versions, for the purpose of range
matching) by setting the `includePrerelease` flag on the options
object to any
[functions](https://github.com/npm/node-semver#functions) that do
range matching.
#### Prerelease Identifiers
The method `.inc` takes an additional `identifier` string argument that
will append the value of the string as a prerelease identifier:
```javascript
semver.inc('1.2.3', 'prerelease', 'beta')
// '1.2.4-beta.0'
```
command-line example:
```bash
$ semver 1.2.3 -i prerelease --preid beta
1.2.4-beta.0
```
Which then can be used to increment further:
```bash
$ semver 1.2.4-beta.0 -i prerelease
1.2.4-beta.1
```
### Advanced Range Syntax
Advanced range syntax desugars to primitive comparators in
deterministic ways.
Advanced ranges may be combined in the same way as primitive
comparators using white space or `||`.
#### Hyphen Ranges `X.Y.Z - A.B.C`
Specifies an inclusive set.
* `1.2.3 - 2.3.4` := `>=1.2.3 <=2.3.4`
If a partial version is provided as the first version in the inclusive
range, then the missing pieces are replaced with zeroes.
* `1.2 - 2.3.4` := `>=1.2.0 <=2.3.4`
If a partial version is provided as the second version in the
inclusive range, then all versions that start with the supplied parts
of the tuple are accepted, but nothing that would be greater than the
provided tuple parts.
* `1.2.3 - 2.3` := `>=1.2.3 <2.4.0-0`
* `1.2.3 - 2` := `>=1.2.3 <3.0.0-0`
#### X-Ranges `1.2.x` `1.X` `1.2.*` `*`
Any of `X`, `x`, or `*` may be used to "stand in" for one of the
numeric values in the `[major, minor, patch]` tuple.
* `*` := `>=0.0.0` (Any version satisfies)
* `1.x` := `>=1.0.0 <2.0.0-0` (Matching major version)
* `1.2.x` := `>=1.2.0 <1.3.0-0` (Matching major and minor versions)
A partial version range is treated as an X-Range, so the special
character is in fact optional.
* `""` (empty string) := `*` := `>=0.0.0`
* `1` := `1.x.x` := `>=1.0.0 <2.0.0-0`
* `1.2` := `1.2.x` := `>=1.2.0 <1.3.0-0`
#### Tilde Ranges `~1.2.3` `~1.2` `~1`
Allows patch-level changes if a minor version is specified on the
comparator. Allows minor-level changes if not.
* `~1.2.3` := `>=1.2.3 <1.(2+1).0` := `>=1.2.3 <1.3.0-0`
* `~1.2` := `>=1.2.0 <1.(2+1).0` := `>=1.2.0 <1.3.0-0` (Same as `1.2.x`)
* `~1` := `>=1.0.0 <(1+1).0.0` := `>=1.0.0 <2.0.0-0` (Same as `1.x`)
* `~0.2.3` := `>=0.2.3 <0.(2+1).0` := `>=0.2.3 <0.3.0-0`
* `~0.2` := `>=0.2.0 <0.(2+1).0` := `>=0.2.0 <0.3.0-0` (Same as `0.2.x`)
* `~0` := `>=0.0.0 <(0+1).0.0` := `>=0.0.0 <1.0.0-0` (Same as `0.x`)
* `~1.2.3-beta.2` := `>=1.2.3-beta.2 <1.3.0-0` Note that prereleases in
the `1.2.3` version will be allowed, if they are greater than or
equal to `beta.2`. So, `1.2.3-beta.4` would be allowed, but
`1.2.4-beta.2` would not, because it is a prerelease of a
different `[major, minor, patch]` tuple.
#### Caret Ranges `^1.2.3` `^0.2.5` `^0.0.4`
Allows changes that do not modify the left-most non-zero element in the
`[major, minor, patch]` tuple. In other words, this allows patch and
minor updates for versions `1.0.0` and above, patch updates for
versions `0.X >=0.1.0`, and *no* updates for versions `0.0.X`.
Many authors treat a `0.x` version as if the `x` were the major
"breaking-change" indicator.
Caret ranges are ideal when an author may make breaking changes
between `0.2.4` and `0.3.0` releases, which is a common practice.
However, it presumes that there will *not* be breaking changes between
`0.2.4` and `0.2.5`. It allows for changes that are presumed to be
additive (but non-breaking), according to commonly observed practices.
* `^1.2.3` := `>=1.2.3 <2.0.0-0`
* `^0.2.3` := `>=0.2.3 <0.3.0-0`
* `^0.0.3` := `>=0.0.3 <0.0.4-0`
* `^1.2.3-beta.2` := `>=1.2.3-beta.2 <2.0.0-0` Note that prereleases in
the `1.2.3` version will be allowed, if they are greater than or
equal to `beta.2`. So, `1.2.3-beta.4` would be allowed, but
`1.2.4-beta.2` would not, because it is a prerelease of a
different `[major, minor, patch]` tuple.
* `^0.0.3-beta` := `>=0.0.3-beta <0.0.4-0` Note that prereleases in the
`0.0.3` version *only* will be allowed, if they are greater than or
equal to `beta`. So, `0.0.3-pr.2` would be allowed.
When parsing caret ranges, a missing `patch` value desugars to the
number `0`, but will allow flexibility within that value, even if the
major and minor versions are both `0`.
* `^1.2.x` := `>=1.2.0 <2.0.0-0`
* `^0.0.x` := `>=0.0.0 <0.1.0-0`
* `^0.0` := `>=0.0.0 <0.1.0-0`
A missing `minor` and `patch` values will desugar to zero, but also
allow flexibility within those values, even if the major version is
zero.
* `^1.x` := `>=1.0.0 <2.0.0-0`
* `^0.x` := `>=0.0.0 <1.0.0-0`
### Range Grammar
Putting all this together, here is a Backus-Naur grammar for ranges,
for the benefit of parser authors:
```bnf
range-set ::= range ( logical-or range ) *
logical-or ::= ( ' ' ) * '||' ( ' ' ) *
range ::= hyphen | simple ( ' ' simple ) * | ''
hyphen ::= partial ' - ' partial
simple ::= primitive | partial | tilde | caret
primitive ::= ( '<' | '>' | '>=' | '<=' | '=' ) partial
partial ::= xr ( '.' xr ( '.' xr qualifier ? )? )?
xr ::= 'x' | 'X' | '*' | nr
nr ::= '0' | ['1'-'9'] ( ['0'-'9'] ) *
tilde ::= '~' partial
caret ::= '^' partial
qualifier ::= ( '-' pre )? ( '+' build )?
pre ::= parts
build ::= parts
parts ::= part ( '.' part ) *
part ::= nr | [-0-9A-Za-z]+
```
## Functions
All methods and classes take a final `options` object argument. All
options in this object are `false` by default. The options supported
are:
- `loose` Be more forgiving about not-quite-valid semver strings.
(Any resulting output will always be 100% strict compliant, of
course.) For backwards compatibility reasons, if the `options`
argument is a boolean value instead of an object, it is interpreted
to be the `loose` param.
- `includePrerelease` Set to suppress the [default
behavior](https://github.com/npm/node-semver#prerelease-tags) of
excluding prerelease tagged versions from ranges unless they are
explicitly opted into.
Strict-mode Comparators and Ranges will be strict about the SemVer
strings that they parse.
* `valid(v)`: Return the parsed version, or null if it's not valid.
* `inc(v, release)`: Return the version incremented by the release
type (`major`, `premajor`, `minor`, `preminor`, `patch`,
`prepatch`, or `prerelease`), or null if it's not valid
* `premajor` in one call will bump the version up to the next major
version and down to a prerelease of that major version.
`preminor`, and `prepatch` work the same way.
* If called from a non-prerelease version, the `prerelease` will work the
same as `prepatch`. It increments the patch version, then makes a
prerelease. If the input version is already a prerelease it simply
increments it.
* `prerelease(v)`: Returns an array of prerelease components, or null
if none exist. Example: `prerelease('1.2.3-alpha.1') -> ['alpha', 1]`
* `major(v)`: Return the major version number.
* `minor(v)`: Return the minor version number.
* `patch(v)`: Return the patch version number.
* `intersects(r1, r2, loose)`: Return true if the two supplied ranges
or comparators intersect.
* `parse(v)`: Attempt to parse a string as a semantic version, returning either
a `SemVer` object or `null`.
### Comparison
* `gt(v1, v2)`: `v1 > v2`
* `gte(v1, v2)`: `v1 >= v2`
* `lt(v1, v2)`: `v1 < v2`
* `lte(v1, v2)`: `v1 <= v2`
* `eq(v1, v2)`: `v1 == v2` This is true if they're logically equivalent,
even if they're not the exact same string. You already know how to
compare strings.
* `neq(v1, v2)`: `v1 != v2` The opposite of `eq`.
* `cmp(v1, comparator, v2)`: Pass in a comparison string, and it'll call
the corresponding function above. `"==="` and `"!=="` do simple
string comparison, but are included for completeness. Throws if an
invalid comparison string is provided.
* `compare(v1, v2)`: Return `0` if `v1 == v2`, or `1` if `v1` is greater, or `-1` if
`v2` is greater. Sorts in ascending order if passed to `Array.sort()`.
* `rcompare(v1, v2)`: The reverse of compare. Sorts an array of versions
in descending order when passed to `Array.sort()`.
* `compareBuild(v1, v2)`: The same as `compare` but considers `build` when two versions
are equal. Sorts in ascending order if passed to `Array.sort()`.
`v2` is greater. Sorts in ascending order if passed to `Array.sort()`.
* `diff(v1, v2)`: Returns difference between two versions by the release type
(`major`, `premajor`, `minor`, `preminor`, `patch`, `prepatch`, or `prerelease`),
or null if the versions are the same.
### Comparators
* `intersects(comparator)`: Return true if the comparators intersect
### Ranges
* `validRange(range)`: Return the valid range or null if it's not valid
* `satisfies(version, range)`: Return true if the version satisfies the
range.
* `maxSatisfying(versions, range)`: Return the highest version in the list
that satisfies the range, or `null` if none of them do.
* `minSatisfying(versions, range)`: Return the lowest version in the list
that satisfies the range, or `null` if none of them do.
* `minVersion(range)`: Return the lowest version that can possibly match
the given range.
* `gtr(version, range)`: Return `true` if version is greater than all the
versions possible in the range.
* `ltr(version, range)`: Return `true` if version is less than all the
versions possible in the range.
* `outside(version, range, hilo)`: Return true if the version is outside
the bounds of the range in either the high or low direction. The
`hilo` argument must be either the string `'>'` or `'<'`. (This is
the function called by `gtr` and `ltr`.)
* `intersects(range)`: Return true if any of the ranges comparators intersect
* `simplifyRange(versions, range)`: Return a "simplified" range that
matches the same items in `versions` list as the range specified. Note
that it does *not* guarantee that it would match the same versions in all
cases, only for the set of versions provided. This is useful when
generating ranges by joining together multiple versions with `||`
programmatically, to provide the user with something a bit more
ergonomic. If the provided range is shorter in string-length than the
generated range, then that is returned.
* `subset(subRange, superRange)`: Return `true` if the `subRange` range is
entirely contained by the `superRange` range.
Note that, since ranges may be non-contiguous, a version might not be
greater than a range, less than a range, *or* satisfy a range! For
example, the range `1.2 <1.2.9 || >2.0.0` would have a hole from `1.2.9`
until `2.0.0`, so the version `1.2.10` would not be greater than the
range (because `2.0.1` satisfies, which is higher), nor less than the
range (since `1.2.8` satisfies, which is lower), and it also does not
satisfy the range.
If you want to know if a version satisfies or does not satisfy a
range, use the `satisfies(version, range)` function.
### Coercion
* `coerce(version, options)`: Coerces a string to semver if possible
This aims to provide a very forgiving translation of a non-semver string to
semver. It looks for the first digit in a string, and consumes all
remaining characters which satisfy at least a partial semver (e.g., `1`,
`1.2`, `1.2.3`) up to the max permitted length (256 characters). Longer
versions are simply truncated (`4.6.3.9.2-alpha2` becomes `4.6.3`). All
surrounding text is simply ignored (`v3.4 replaces v3.3.1` becomes
`3.4.0`). Only text which lacks digits will fail coercion (`version one`
is not valid). The maximum length for any semver component considered for
coercion is 16 characters; longer components will be ignored
(`10000000000000000.4.7.4` becomes `4.7.4`). The maximum value for any
semver component is `Number.MAX_SAFE_INTEGER || (2**53 - 1)`; higher value
components are invalid (`9999999999999999.4.7.4` is likely invalid).
If the `options.rtl` flag is set, then `coerce` will return the right-most
coercible tuple that does not share an ending index with a longer coercible
tuple. For example, `1.2.3.4` will return `2.3.4` in rtl mode, not
`4.0.0`. `1.2.3/4` will return `4.0.0`, because the `4` is not a part of
any other overlapping SemVer tuple.
### Clean
* `clean(version)`: Clean a string to be a valid semver if possible
This will return a cleaned and trimmed semver version. If the provided
version is not valid a null will be returned. This does not work for
ranges.
ex.
* `s.clean(' = v 2.1.5foo')`: `null`
* `s.clean(' = v 2.1.5foo', { loose: true })`: `'2.1.5-foo'`
* `s.clean(' = v 2.1.5-foo')`: `null`
* `s.clean(' = v 2.1.5-foo', { loose: true })`: `'2.1.5-foo'`
* `s.clean('=v2.1.5')`: `'2.1.5'`
* `s.clean(' =v2.1.5')`: `2.1.5`
* `s.clean(' 2.1.5 ')`: `'2.1.5'`
* `s.clean('~1.0.0')`: `null`
