Test, validate and match regular expressions
Matches double-quoted strings that contain no whitespace, while allowing escaped quotes (\") within the content. The pattern starts and ends with a literal double quote, and the inner portion consists of zero or more occurrences of either an escaped quote or any character that is not whitespace and not a quote. With global and multiline flags, it is useful for extracting compact quoted tokens (like identifiers or flags) from logs, configs, or code across multiple lines.
