Tab completion using fzf in zsh, bash, GNU readline apps (e.g. python, php -a etc.)

This is distinct from fzf's own implementation for completion, in that it works with the existing completion mechanisms rather than creating a new mechanism.

1. You need to install fzf first.
2. Clone this repository: git clone https://github.com/lincheney/fzf-tab-completon ...
   • you can also choose to download only the scripts you need, up to you.
3. Follow instructions on how to set up for:
   • zsh
   • bash
   • readline
4. The following environment variables are supported, just as in fzf's "vanilla" completion.
   • $FZF_TMUX_HEIGHT
   • $FZF_COMPLETION_OPTS
   • $FZF_DEFAULT_OPTS See also https://github.com/junegunn/fzf#settings

Add to your ~/.zshrc:

source /path/to/fzf-tab-completion/zsh/fzf-zsh-completion.sh
bindkey '^I' fzf_completion

If you have also enabled fzf's zsh completion, then the bindkey line is optional.

Note that this does not provide **-style triggers, you will need to enable fzf's zsh completion as well.

By default, display strings are shown but cannot be searched in fzf. This is configurable via zstyle:

# only for git
zstyle ':completion:*:*:git' fzf-search-display true
# or for everything
zstyle ':completion:*' fzf-search-display true

Add to your ~/.bashrc:

source /path/to/fzf-tab-completion/bash/fzf-bash-completion.sh
bind -x '"\t": fzf_bash_completion'

If you are using a bash that is dynamically linked against readline (LD_PRELOAD= ldd $(which bash)) you may prefer (or not!) to use the readline method instead.

NOTE: This uses a LD_PRELOAD hack, is only supported on Linux and only for GNU readline (not e.g. libedit or other readline alternatives).

1. Install https://github.com/lincheney/rl_custom_function/
   • consider adding export LD_PRELOAD=/path/to/librl_custom_function.so to your ~/.zshrc or ~/.bashrc
2. Run: cd /path/to/fzf-tab-completion/readline/ && cargo build --release
3. Copy/symlink /path/to/fzf-tab-completion/readline/bin/rl_custom_complete into your $PATH
4. Add to your ~/.inputrc:

$include function rl_custom_complete /path/to/fzf-tab-completion/readline/target/release/librl_custom_complete.so
"\t": rl_custom_complete

These are the applications that I have seen working:

• python2, python3
• php -a
• R
• lftp
• irb --legacy (the new irb in ruby 2.7 uses ruby-reline instead of readline)
• gdb
• sqlite3

• https://github.com/rockandska/fzf-obc (fzf tab completion in bash)
• https://github.com/Aloxaf/fzf-tab (fzf tab completion in zsh)
• https://github.com/lincheney/rl_custom_isearch (fzf for history search in all readline applications)
