junegunn/fzf 0.34.0 on GitHub

Added support for adaptive --height. If the --height value is prefixed
with ~, fzf will automatically determine the height in the range according
to the input size.

seq 1 | fzf --height ~70% --border --padding 1 --margin 1
seq 10 | fzf --height ~70% --border --padding 1 --margin 1
seq 100 | fzf --height ~70% --border --padding 1 --margin 1

There are a few limitations

Not compatible with percent top/bottom margin/padding

# This is not allowed (top/bottom margin in percent value)
fzf --height ~50% --border --margin 5%,10%

# This is allowed (top/bottom margin in fixed value)
fzf --height ~50% --border --margin 2,10%

fzf will not start until it can determine the right height for the input

# fzf will open immediately
(sleep 2; seq 10) | fzf --height 50%

# fzf will open after 2 seconds
(sleep 2; seq 10) | fzf --height ~50%
(sleep 2; seq 1000) | fzf --height ~50%

Fixed tcell renderer used to render full-screen fzf on Windows
--no-clear is deprecated. Use reload action instead.
