Regex Matcher

Handy tool for creating and testing regular expressions (regex)

Minimalist regular expressions editor for creating and testing regular expressions (regex) against a set of sample text. Test regular expressions against patterns, such as: - Email address - IP Addresses - URLs - Usernames and many other common and unique pattern combinations. Features: - Light/dark editor - Matched characters highlighted - Set regex flags (using the supported flag characters) - Cheatsheet of common regular expression symbols Supported Regex Flags: g - global match; find all matches rather than stopping after the first match i - ignore case; if u flag is also enabled, use Unicode case folding m - multiline; treat beginning and end characters (^ and $) as working over multiple lines (i.e., match the beginning or end of each line (delimited by \n or \r), not only the very beginning or end of the whole input string) u - Unicode; treat pattern as a sequence of Unicode code points y - sticky; matches only from the index indicated by the lastIndex property of this regular expression in the target string (and does not attempt to match from any later indexes).
