Replacements are aware of variables, which are made accessible for use through regex capture groups. Capture groups can be numbered, or optionally named. The zeroth capture group corresponds to the entire match. $ echo 'Swap It' | srgn '(\w+) (\w+)' '$2 $1' # Regular, numbered It ...
Getting In A State Using Flyway Baseline Migrations Flyway Teams baseline migration scripts are a simple and fast way to deploy new copies of a database, at a specific version, for testing work, or to create a new branch during development....
Note that multiple line modifier (m) is set when executed, so put (?-m) at the beginning of regex if you want to explicitly disable it.Order of capture group in the pattern is not guaranteed. Please avoid to use direct index, and use relative or named capture group instead. For ...
It's because my second capture group doesn't explicity exclude a close double chevron. Once you have identical nesting markers, then regex aren't really the best tool for sorting 'em out. It's why we're told Never Parse Tag Formats Using Regex, right...
needing to capture groups of information. Sometimes, regex is not enough to solve complex problems. If you’re trying to parse a programming language, you need to deal with nested structures. Now, it’s time to start exploring on how to build a micro-engine for a derived Regular Exp...

Backreference will provide the string that was matched, not the pattern that was inside the capture group. For example, if ([0-9][a-f]) matches 3b, then backreferencing will give 3b and not any other valid match like 8f, 0a etc. This is akin to how variables behave in programming,...
