the FZF_DEFAULT_OPTS set as below:

FZF_DEFAULT_OPTS="--inline-info --info=inline "
FZF_DEFAULT_OPTS+="--info-command='echo \"\x1b[33;1m\$FZF_POS\x1b[m/\$FZF_INFO\"' "

export FZF_DEFAULT_OPTS

result

$ echo $FZF_DEFAULT_OPTS 
--inline-info --info=inline --info-command='echo "\x1b[33;1m$FZF_POS\x1b[m/$FZF_INFO"'

  $ unset FZF_DEFAULT_OPTS; \
    export FZF_DEFAULT_OPTS='--height 35% --min-height 8+'; \
    echo $FZF_DEFAULT_OPTS 
  --height 35% --min-height 8+

    export FZF_DEFAULT_OPTS="--height 35% --min-height 8+ --inline-info --info=inline --info-command='echo \"\x1b[33;1m\$FZF_POS\x1b[m/\$FZF_INFO\"' "; \

Inline info doesn't show the spinner, unfortunately. But if you look closely, the color of < changes when the loading is complete, from the color of spinner to the color of prompt.

fzf --color spinner:red,prompt:yellow --info 'inline: look-at-me ' < <(sleep 3)

thanks @junegunn, yes I do see the color changes ( as below ). By the way, will you integrate the spinner feature into inline mode in the future ?

[junegunn]

I don't know where to put it, and that's why I introduced the color change in the first place when I added the inline option as an alternative way to show the loading status.

maybe somewhere we can define it in the info line, something like:

#                  something like this
#                         v
--info-command='echo "$SPINNER \x1b[33;1m$FZF_POS\x1b[m/$FZF_INFO"'
