What Is a Regular Expression?
A regular expression (regex) is a sequence of characters that defines a search pattern. Regex is used in programming, text editors, and command-line tools to find, match, and manipulate text. Writing regex can be tricky, so this tool generates patterns from plain English descriptions.
