Since 0.24.0, fzf can render partial preview content before the preview command
|
|
|
|
|
completes. ANSI escape sequence for clearing the display (\fBCSI 2 J\fR) is
|
|
|
|
|
supported, so you can use it to implement preview window that is constantly
|
|
|
|
|
updating.

\fBfzf --preview 'for i in $(seq 100000); do

(( i % 200 == 0 )) && printf "\\033[2J"
