fzy is a fast, simple fuzzy text selector for the terminal with an advanced scoring algorithm.
It's been kind of life-changing. -@graygilmore
fzy works great btw -@alexblackie
fzy is faster and shows better results than other fuzzy finders.
Most other fuzzy matchers sort based on the length of a match. fzy tries to find the result the user intended. It does this by favouring matches on consecutive letters and starts of words. This allows matching using acronyms or different parts of the path.
A gory comparison of the sorting used by fuzzy finders can be found in ALGORITHM.md
fzy is designed to be used both as an editor plugin and on the command line. Rather than clearing the screen, fzy displays its interface directly below the current cursor position, scrolling the screen if necessary.
brew install fzy
sudo port install fzy
pacman -S fzy
pkg install fzy
emerge -av app-shells/fzy
pkgsrc (NetBSD and others):
pkgin install fzy
zypper in fzy
make sudo make install
PREFIX environment variable can be used to specify the install location,
the default is
fzy can be easily integrated with vim.

Any program can be used to filter files presented through fzy. ag (the silver searcher) can be used to ignore files specified by
nnoremap <leader>e :call FzyCommand("ag . --silent -l -g ''", ":e")<cr> nnoremap <leader>v :call FzyCommand("ag . --silent -l -g ''", ":vs")<cr> nnoremap <leader>s :call FzyCommand("ag . --silent -l -g ''", ":sp")<cr>
fzy attempts to present the best matches first. The following considerations are weighted when sorting:
It prefers consecutive characters:
file will match file over filter.
It prefers matching the beginning of words:
amp is likely to match app/models/posts.rb.
It prefers shorter matches:
abce matches abcdef over abc de.
It prefers shorter candidates:
test matches tests over testing.
