Syntax	Description
`*`	Matches any character, except for the path separator, zero or more times.
`**`	Matches any character zero or more times. If it doesn't span the entire length of a path segment it's interpreted as a `*` instead.
`?`	Matches any character, except for the path separator, one time.
`\`	Matches the character after it in the glob literally. This is the escape operator.
`[abc]`	Matches any of the characters in the class one time.
`[a-z]`	Matches any of the characters in the range in the class one time.
`[^abc]`	Matches any character, except for the characters the class, and the path separator, o∏ne time. Aliased as `[!abc]` also.
`[^a-z]`	Matches any character, except for the characters in the range in the class, and the path separator, one time. Aliased as `[!a-z]` also.
`{foo,bar}`	Matches any of the alternations, which are separated by a comma, inside the braces.
`{01..99}`	Matches any of the numbers in the expanded range. Padding is supported and opt-in.
`{a..zz}`	Matches any of the strings in the expanded range. Upper-cased ranges are supported and opt-in.
`!glob`	Matches anything except the provided glob. Negations can only be used at the start of the glob.
`!!glob`	Matches the provided glob. Negations can only be used at the start of the glob.

Additional features and details:

Zeptomatch works pretty similarly to picomatch, since 1000+ of its tests are being used by this library.
Zeptomatch is opinionated, there are no options at all, which helps with keeping it tiny and manageable.
Zeptomatch is automatically memoized, the only ways to use it are always the most optimized ones available.
Zeptomatch automatically normalizes path separators, since matching Windows-style paths would most likely be a mistake.
Zeptomatch supports compiling a glob to a standalone regular expression.
Zeptomatch doesn't do anything special for file names starting with a dot.
Zeptomatch supports nesting braces indefinitely.

Limitations:

POSIX classes (e.g. [:alnum:]) are not supported. Implementing them seems a bit out of scope for a "zepto"-level library.
Extglobs (e.g. ?(foo)) are not supported. They might be in the future though.

Install

npm install --save zeptomatch

Usage

import zeptomatch from 'zeptomatch';

// Check if a glob matches a path

zeptomatch ( '*.js', 'abcd' ); // => false
zeptomatch ( '*.js', 'a.js' ); // => true
zeptomatch ( '*.js', 'a.md' ); // => false
zeptomatch ( '*.js', 'a/b.js' ); // => false

// Compile a glob to a regular expression

const re = zeptomatch.compile ( '*.js' ); // => /^[^/]*\.js$/s

// Escape a glob to a string that will be matched as is

const escaped = zeptomatch.escape ( '*.js' ); // => '\\*\\.js'
