# matcher [](https://travis-ci.com/sindresorhus/matcher)
|
|
|
|
> Simple [wildcard](https://en.wikipedia.org/wiki/Wildcard_character) matching
|
|
|
|
Useful when you want to accept loose string input and regexes/globs are too convoluted.
|
|
|
|
## Install
|
|
|
|
```
|
|
$ npm install matcher
|
|
```
|
|
|
|
## Usage
|
|
|
|
```js
|
|
const matcher = require('matcher');
|
|
|
|
matcher(['foo', 'bar', 'moo'], ['*oo', '!foo']);
|
|
//=> ['moo']
|
|
|
|
matcher(['foo', 'bar', 'moo'], ['!*oo']);
|
|
//=> ['bar']
|
|
|
|
matcher.isMatch('unicorn', 'uni*');
|
|
//=> true
|
|
|
|
matcher.isMatch('unicorn', '*corn');
|
|
//=> true
|
|
|
|
matcher.isMatch('unicorn', 'un*rn');
|
|
//=> true
|
|
|
|
matcher.isMatch('rainbow', '!unicorn');
|
|
//=> true
|
|
|
|
matcher.isMatch('foo bar baz', 'foo b* b*');
|
|
//=> true
|
|
|
|
matcher.isMatch('unicorn', 'uni\\*');
|
|
//=> false
|
|
|
|
matcher.isMatch('UNICORN', 'UNI*', {caseSensitive: true});
|
|
//=> true
|
|
|
|
matcher.isMatch('UNICORN', 'unicorn', {caseSensitive: true});
|
|
//=> false
|
|
|
|
matcher.isMatch(['foo', 'bar'], 'f*');
|
|
//=> true
|
|
|
|
matcher.isMatch(['foo', 'bar'], ['a*', 'b*']);
|
|
//=> true
|
|
|
|
matcher.isMatch('unicorn', ['tri*', 'UNI*'], {caseSensitive: true});
|
|
//=> false
|
|
```

## API
|
|
|
|
It matches even across newlines. For example, `foo*r` will match `foo\nbar`.
|
|
|
|
### matcher(inputs, patterns, options?)
|
|
|
|
Accepts an array of `input`'s and `pattern`'s.
|
|
|
|
Returns an array of `inputs` filtered based on the `patterns`.
|
|
|
|
### matcher.isMatch(input, pattern, options?)
|
|
|
|
Accepts either a string or array of strings for both `input` and `pattern`.
|
|
|
|
Returns a `boolean` of whether any given `input` matches every given `pattern`.
|
|
|
|
#### input
|
|
|
|
Type: `string | string[]`
|
|
|
|
String or array of strings to match.
|
|
|
|
#### options
|
|
|
|
Type: `object`
|
|
|
|
##### caseSensitive
|
|
|
|
Type: `boolean`\
|
|
Default: `false`
|
|
|
|
Treat uppercase and lowercase characters as being the same.
|
|
|
|
Ensure you use this correctly. For example, files and directories should be matched case-insensitively, while most often, object keys should be matched case-sensitively.
|
|
|
|
#### pattern
|
|
|
|
Type: `string | string[]`
|
|
|
|
Use `*` to match zero or more characters. A pattern starting with `!` will be negated.
|
|
