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:
/foo (\w+)/ replace with bar $1)Supported file encodings:
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:

First and foremost, make sure you've installed ripgrep (AKA: rg).
