mathiasrw/rexreplace ? reverse-engineered prompt

Build me a simple command line tool for finding and replacing text across files.

I want to be able to pass a search pattern, a replacement, and one or more file globs so I can target exactly the files I want instead of hacking together a bunch of shell commands. It should support regular expressions, including capture groups, and let the replacement be plain text or a little JavaScript expression when I need something dynamic like pulling a version number or using file info.

Make it feel safe and easy to use, with clear defaults and examples that work from the terminal, including a shorter alias like rr if that fits. It should handle recursive file matching with glob patterns, work nicely in scripts, and have a few good tests so common cases like multiline matches, escaped characters, and group replacements keep working. If you need to check current docs for anything, look them up online.
