[fzf-tmux] Add option to start fzf in tmux popup window
Requires latest tmux built from source (e.g. brew install tmux --HEAD) Examples: # 50%/50% width and height on the center of the screen fzf-tmux -p # 80%/80% fzf-tmux -p80% # 80%/40% fzf-tmux -p80%,40% # Separate -w and -h fzf-tmux -w80% -h40% # 80%/40% at position (0, 0) fzf-tmux -w80% -h40% -x0 -y0 You can configure key bindings and fuzzy completion to open in tmux popup window like so: FZF_TMUX_OPTS='-p 80%'
