Tokenizes a string that represents a regular expression.

Spec-compliant polyfill for String.prototype.matchAll

POSIX character classes for creating regular expressions.

Generate a regex from a string or array of strings.

Fast, minimal glob matcher for node.js. Similar to micromatch, minimatch and multimatch, but complete Bash 4.3 wildcard support only (no support for exglobs, posix brackets or braces)
