repgrep (rgr)

An interactive replacer for ripgrep.

This is an interactive command line tool to make find and replacement easy. It uses ripgrep to find, and then provides you with a simple interface to see the replacements in real-time and conditionally replace matches.

Some features:

  • ⚡ Super fast search results
  • ✨ Interactive interface for selecting which matches should be replaced or not
  • 🕶️ Live preview of the replacements
  • 🧠 Replace using capturing groups (e.g., when using /foo (\w+)/ replace with bar $1)
  • 🦀 and more!

Supported file encodings:

  • UTF8
  • UTF16BE
  • UTF16LE

Other encodings are possibly supported but untested at the moment. See this issue for more information.


After installing, just use rgr (think: rg + replace).

The arguments are:

rgr <rg arguments> # See `rgr --help` for more details

Here's an example where we ran the command:

rgr -C5 dreamcast

And have entered the replacement flycast:
