matcher

matcher

Simple wildcard matching

Useful when you want to accept loose string input and regexes/globs are too convoluted.

Install

$ npm install matcher

Usage

const matcher = require('matcher');

matcher(['foo', 'bar', 'moo'], ['*oo', '!foo']);
//=> ['moo']

matcher(['foo', 'bar', 'moo'], ['!*oo']);
//=> ['bar']

matcher('moo', ['']);
//=> []

matcher('moo', []);
//=> []

matcher([''], ['']);
//=> ['']

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

matcher.isMatch('unicorn', ['']);
//=> false

matcher.isMatch('unicorn', []);
//=> false

matcher.isMatch([], 'bar');
//=> false

matcher.isMatch([], []);
//=> false

matcher.isMatch('', '');
//=> true

API

It matches even across newlines. For example, foo*r will match foo\nbar.

matcher(inputs, patterns, options?)

Accepts a string or an array of strings for both inputs and patterns.

Returns an array of inputs filtered based on the patterns.

matcher.isMatch(input, pattern, options?)

Accepts a string or an array of strings for both inputs and patterns.

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.

Benchmark

$ npm run bench
