JavaScript RegExp - close to PCRE. Lookbehind, named groups and Unicode property escapes work in modern browsers. Possessive quantifiers and recursive patterns are not supported.
Switch to 'Exclude matching' mode - equivalent to grep -v. The output will contain every line that did not match your pattern.
Patterns are applied per line, so ^ and $ anchor to the start and end of each line by default. To match across lines, you'd need to disable the line-split - currently this tool always splits on newlines.
No - matching is case-sensitive unless you toggle the 'ignore case' option, which adds the i regex flag.
Streamline your data analysis and isolate exactly what you need with this efficient Text Grep tool.
