fzf/src/README.md

fzf in Go

This directory contains the source code for the new fzf implementation in Go. This new version has the following benefits over the previous Ruby version.

• Immensely faster
  • No GIL. Performance is linearly proportional to the number of cores.
  • It's so fast that I even decided to remove the sort limit (--sort=N)
• Does not require Ruby and distributed as an executable binary
  • Ruby dependency is especially painful on Ruby 2.1 or above which ships without curses gem

Build

# Build fzf executable
make

# Install the executable to ../bin directory
make install

# Build executable for Linux x86_64 using Docker
make linux64

Contribution

For the moment, I will not add or accept any new features until we can be sure that the implementation is stable and we have a sufficient number of test cases. However, fixes for obvious bugs and new test cases are welcome.

I also care much about the performance of the implementation (that's the reason I rewrote the whole thing in Go, right?), so please make sure that your change does not result in performance regression. Please be minded that we still don't have a quantitative measure of the performance.
