Build, test, and debug regular expressions
This regex matches key-value pairs prefixed with 'bb-', where the key can contain word characters, dots, and an optional colon-led segment, followed by an equals sign and a quoted value of word characters, dots, or colons. It is useful for extracting bb- prefixed attributes from text, such as configuration strings or markup-like content. The flags enable case-insensitive and multiline matching.
