I was wondering if fzf_default_opts couldn't be set outside like this:
zstyle ':fzf-tab:*' fzf-default-opts $FZF_DEFAULT_OPTS
?

I that case you could get ride off the use_fzf_default_opts option.

Yeah I was going for a quick change so didn't try that. I thought zstyle might parse things differently and lead to unintended behaviors.

Let me try that and get back here.

Ah I remember it now. Since FZF_DEFAULT_OPTS is a bunch of flags, we need to pass it as such and not as an environment variable.

And fzf-flags already exists in the plugin. But when I tried setting that equal to the flags in FZF_DEFAULT_OPTS (see below), it wasn't working. I think the reason is the same as what I mentioned in #475 (comment).

# this converts the string to a string array which is expected by fzf-flags.
export parsed_fzf_default_opts=(${=FZF_DEFAULT_OPTS})

zstyle ':fzf-tab:*' fzf-flags $parsed_fzf_default_opts

Your suggestion doesn't seem to be working for my case:

export FZF_DEFAULT_OPTS="          \
  --exact                          \
  --height ${FZF_TMUX_HEIGHT:-30%} \
  --layout=reverse                 \
  --info=hidden                    \
  --prompt='$  '                   \
  --pointer='=>'                   \
  --marker='+'                     \
  --cycle                          \
  --select-1                       \
  --color=dark                     \
  --bind '?:toggle-preview,ctrl-a:select-all,ctrl-d:half-page-down,ctrl-u:half-page-up,ctrl-l:clear-query,home:first,end:last,enter:accept-non-empty,alt-down:down,alt-up:up,right:accept-non-empty,alt-right:accept-non-empty,alt-left:close,left:close' \
  --color='fg:-1,bg:-1,hl:#fb8aa4,fg+:-1,bg+:-1,hl+:#55E579' \
  --color='info:#af87ff,prompt:#fb8aa4,pointer:#55E579,marker:#55E579,spinner:#55E579'
"

I think the --height ${FZF_TMUX_HEIGHT:-30%} is not correctly handle.

@pablospe can you try this?

zstyle ':fzf-tab:*' fzf-flags ${(Q)${(Z:nC:)FZF_DEFAULT_OPTS}}

This is magic! It is working, thanks!

These are my flags,

# Set fzf options
export FZF_DEFAULT_OPTS=$FZF_DEFAULT_OPTS'
    --color=bg:#1b1b1b
    --color=preview-bg:#1b1b1b
    --color=hl+:#fb4934
    --color=gutter:#1b1b1b
    --color=pointer:#f9f5d7,marker:#f9f5d7
    --color=info:#ebdbb2,spinner:#f9f5d7
    --color=query:#ebdbb2,prompt:#ebdbb2
    --color=border:#ebdbb2
    --border="rounded" --prompt="> "
    --marker="" --pointer="->" --layout="reverse"
'

While echo ${(Q)${(Z:nC:)FZF_DEFAULT_OPTS}} looks as expected, when I try to open fzf-tab, it fails with an eval error.
