rff is a fast, simple fuzzy selector for the terminal with an advanced scoring algorithm and full UTF-8 support.

Pre-compiled binaries are available for common architectures, starting with version 0.3.0.

If you have a Rust toolchain installed, you can also build rff from source via Cargo:

$ cargo install rff

rff is a drop-in replacement for other fuzzy selection tools such as fzy or selecta.

Its interface is straightforward:

• pass it a set of choices on STDIN
• it will present a fuzzy selection interface to the user, and block until they make a selection or quit with ^C
• it will print the user's selection on STDOUT

As an example, you can say:

$ vim $(find . -type f | rff)

Which prompts the user to select a file in or below the current directory, and then opens the selected file in vim.

rff supports these keys:

• ^N to select the next match
• ^P to select the previous match
• ^U to clear the search query
• ^C, ^D, and Esc to exit without selecting a match

rff is currently based on fzy's scoring algoritm. For details on how this is better than most fuzzy finders, see fzy's ALGORITHM.md.
