# ignore
`ignore` is a manager, filter and parser which implemented in pure JavaScript according to the .gitignore [spec](http://git-scm.com/docs/gitignore).
Pay attention that [`minimatch`](https://www.npmjs.org/package/minimatch) does not work in the gitignore way. To filter filenames according to .gitignore file, I recommend this module.
##### Tested on
- Linux + Node: `0.8` - `7.x`
- Windows + Node: `0.10` - `7.x`, node < `0.10` is not tested due to the lack of support of appveyor.
Actually, `ignore` does not rely on any versions of node specially.
Since `4.0.0`, ignore will no longer support `node < 6` by default, to use in node < 6, `require('ignore/legacy')`. For details, see [CHANGELOG](https://github.com/kaelzhang/node-ignore/blob/master/CHANGELOG.md).
## Table Of Main Contents
- [Usage](#usage)
- [`Pathname` Conventions](#pathname-conventions)
- [Guide for 2.x -> 3.x](#upgrade-2x---3x)
- [Guide for 3.x -> 4.x](#upgrade-3x---4x)
- See Also:
- [`glob-gitignore`](https://www.npmjs.com/package/glob-gitignore) matches files using patterns and filters them according to gitignore rules.
## Usage
```js
import ignore from 'ignore'
const ig = ignore().add(['.abc/*', '!.abc/d/'])
```
### Filter the given paths
```js
const paths = [
'.abc/a.js', // filtered out
'.abc/d/e.js' // included
]
ig.filter(paths) // ['.abc/d/e.js']
ig.ignores('.abc/a.js') // true
```
### As the filter function
```js
paths.filter(ig.createFilter()); // ['.abc/d/e.js']
```
### Win32 paths will be handled
```js
ig.filter(['.abc\\a.js', '.abc\\d\\e.js'])
// if the code above runs on windows, the result will be
// ['.abc\\d\\e.js']
```
## Why another ignore?
- `ignore` is a standalone module, and is much simpler so that it could easy work with other programs, unlike [isaacs](https://npmjs.org/~isaacs)'s [fstream-ignore](https://npmjs.org/package/fstream-ignore) which must work with the modules of the fstream family.
- `ignore` only contains utility methods to filter paths according to the specified ignore rules, so
- `ignore` never try to find out ignore rules by traversing directories or fetching from git configurations.
- `ignore` don't cares about sub-modules of git projects.
- Exactly according to [gitignore man page](http://git-scm.com/docs/gitignore), fixes some known matching issues of fstream-ignore, such as:
- '`/*.js`' should only match '`a.js`', but not '`abc/a.js`'.
- '`**/foo`' should match '`foo`' anywhere.
- Prevent re-including a file if a parent directory of that file is excluded.
- Handle trailing whitespaces:
- `'a '`(one space) should not match `'a '`(two spaces).
- `'a \ '` matches `'a '`
- All test cases are verified with the result of `git check-ignore`.
# Methods
## .add(pattern: string | Ignore): this
## .add(patterns: Array<string | Ignore>): this
- **pattern** `String | Ignore` An ignore pattern string, or the `Ignore` instance
- **patterns** `Array<String | Ignore>` Array of ignore patterns.
Adds a rule or several rules to the current manager.
Returns `this`
Notice that a line starting with `'#'`(hash) is treated as a comment. Put a backslash (`'\'`) in front of the first hash for patterns that begin with a hash, if you want to ignore a file with a hash at the beginning of the filename.
```js
ignore().add('#abc').ignores('#abc') // false
ignore().add('\#abc').ignores('#abc') // true
```
`pattern` could either be a line of ignore pattern or a string of multiple ignore patterns, which means we could just `ignore().add()` the content of a ignore file:
```js
ignore()
.add(fs.readFileSync(filenameOfGitignore).toString())
.filter(filenames)
```
`pattern` could also be an `ignore` instance, so that we could easily inherit the rules of another `Ignore` instance.
## <strike>.addIgnoreFile(path)</strike>
REMOVED in `3.x` for now.
To upgrade `ignore@2.x` up to `3.x`, use
```js
import fs from 'fs'
if (fs.existsSync(filename)) {
ignore().add(fs.readFileSync(filename).toString())
}
```
instead.
## .filter(paths: Array<Pathname>): Array<Pathname>
```ts
type Pathname = string
```
Filters the given array of pathnames, and returns the filtered array.
- **paths** `Array.<Pathname>` The array of `pathname`s to be filtered.
### `Pathname` Conventions:
#### 1. `Pathname` should be a `path.relative()`d pathname
`Pathname` should be a string that have been `path.join()`ed, or the return value of `path.relative()` to the current directory.
```js
// WRONG
ig.ignores('./abc')
// WRONG, for it will never happen.
// If the gitignore rule locates at the root directory,
// `'/abc'` should be changed to `'abc'`.
// ```
// path.relative('/', '/abc') -> 'abc'
// ```
ig.ignores('/abc')
// Right
ig.ignores('abc')
// Right
ig.ignores(path.join('./abc')) // path.join('./abc') -> 'abc'
```
In other words, each `Pathname` here should be a relative path to the directory of the gitignore rules.
Suppose the dir structure is:
```
/path/to/your/repo
|-- a
| |-- a.js
|
|-- .b
|
|-- .c
|-- .DS_store
```
Then the `paths` might be like this:
```js
[
'a/a.js'
'.b',
'.c/.DS_store'
]
```
Usually, you could use [`glob`](http://npmjs.org/package/glob) with `option.mark = true` to fetch the structure of the current directory:
```js
import glob from 'glob'
glob('**', {
// Adds a / character to directory matches.
mark: true
}, (err, files) => {
if (err) {
return console.error(err)
}
let filtered = ignore().add(patterns).filter(files)
console.log(filtered)
})
```
#### 2. filenames and dirnames
`node-ignore` does NO `fs.stat` during path matching, so for the example below:
```js
ig.add('config/')
// `ig` does NOT know if 'config' is a normal file, directory or something
ig.ignores('config') // And it returns `false`
ig.ignores('config/') // returns `true`
```
Specially for people who develop some library based on `node-ignore`, it is important to understand that.
## .ignores(pathname: Pathname): boolean
> new in 3.2.0
Returns `Boolean` whether `pathname` should be ignored.
```js
ig.ignores('.abc/a.js') // true
```
## .createFilter()
Creates a filter function which could filter an array of paths with `Array.prototype.filter`.
Returns `function(path)` the filter function.
## `options.ignorecase` since 4.0.0
Similar as the `core.ignorecase` option of [git-config](https://git-scm.com/docs/git-config), `node-ignore` will be case insensitive if `options.ignorecase` is set to `true` (default value), otherwise case sensitive.
```js
const ig = ignore({
ignorecase: false
})
ig.add('*.png')
ig.ignores('*.PNG') // false
```
****
# Upgrade Guide
## Upgrade 2.x -> 3.x
- All `options` of 2.x are unnecessary and removed, so just remove them.
- `ignore()` instance is no longer an [`EventEmitter`](nodejs.org/api/events.html), and all events are unnecessary and removed.
- `.addIgnoreFile()` is removed, see the [.addIgnoreFile](#addignorefilepath) section for details.
## Upgrade 3.x -> 4.x
Since `4.0.0`, `ignore` will no longer support node < 6, to use `ignore` in node < 6:
```js
var ignore = require('ignore/legacy')
```

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 >=3.4*
## 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-exactly-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.
- [`ValueOf`](source/value-of.d.ts) - Create a union of the given object's values, and optionally specify which keys to get the values from.
- [`PromiseValue`](source/promise-value.d.ts) - Returns the type that is wrapped inside a `Promise`.
- [`AsyncReturnType`](source/async-return-type.d.ts) - Unwrap the return type of a function that returns a `Promise`.
- [`ConditionalKeys`](source/conditional-keys.d.ts) - Extract keys from a shape where values extend the given `Condition` type.
- [`ConditionalPick`](source/conditional-pick.d.ts) - Like `Pick` except it selects properties from a shape where the values extend the given `Condition` type.
- [`ConditionalExcept`](source/conditional-except.d.ts) - Like `Omit` except it removes properties from a shape where the values extend the given `Condition` type.
- [`UnionToIntersection`](source/union-to-intersection.d.ts) - Convert a union type to an intersection type.
- [`Stringified`](source/stringified.d.ts) - Create a type with the keys of the given type changed to `string` type.
- [`FixedLengthArray`](source/fixed-length-array.d.ts) - Create a type that represents an array of the given type and length.
- [`IterableElement`](source/iterable-element.d.ts) - Get the element type of an `Iterable`/`AsyncIterable`. For example, an array or a generator.
- [`Entry`](source/entry.d.ts) - Create a type that represents the type of an entry of a collection.
- [`Entries`](source/entries.d.ts) - Create a type that represents the type of the entries of a collection.
- [`SetReturnType`](source/set-return-type.d.ts) - Create a function type with a return type of your choice and the same parameters as the given function type.
- [`Asyncify`](source/asyncify.d.ts) - Create an async version of the given function type.
### Template literal types
*Note:* These require [TypeScript 4.1 or newer](https://devblogs.microsoft.com/typescript/announcing-typescript-4-1/#template-literal-types).
- [`CamelCase`](ts41/camel-case.d.ts) – Convert a string literal to camel-case (`fooBar`).
- [`KebabCase`](ts41/kebab-case.d.ts) – Convert a string literal to kebab-case (`foo-bar`).
- [`PascalCase`](ts41/pascal-case.d.ts) – Converts a string literal to pascal-case (`FooBar`)
- [`SnakeCase`](ts41/snake-case.d.ts) – Convert a string literal to snake-case (`foo_bar`).
- [`DelimiterCase`](ts41/delimiter-case.d.ts) – Convert a string literal to a custom string delimiter casing.
### Miscellaneous
- [`PackageJson`](source/package-json.d.ts) - Type for [npm's `package.json` file](https://docs.npmjs.com/creating-a-package-json-file).
- [`TsConfigJson`](source/tsconfig-json.d.ts) - Type for [TypeScript's `tsconfig.json` file](https://www.typescriptlang.org/docs/handbook/tsconfig-json.html) (TypeScript 3.7).
## 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.
- [`SubType`](https://github.com/sindresorhus/type-fest/issues/22) - The type is powerful, but lacks good use-cases and is prone to misuse.
- [`ExtractProperties` and `ExtractMethods`](https://github.com/sindresorhus/type-fest/pull/4) - The types violate the single responsibility principle. Instead, refine your types into more granular type hierarchies.
## 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.

Create a type from an object type without certain keys.
This type is a stricter version of [`Omit`](https://www.typescriptlang.org/docs/handbook/release-notes/typescript-3-5.html#the-omit-helper-type). The `Omit` type does not restrict the omitted keys to be keys present on the given type, while `Except` does. The benefits of a stricter type are avoiding typos and allowing the compiler to pick up on rename refactors automatically.
