unsupported style preset: %s

Error message

unsupported style preset: %s

What it means

applyPreset only accepts the built-in style preset names (default, minimal, etc.) or a composite 'full[:border]' value. Any other string falls into the default case, where a SplitN on ':' must yield tokens[0] == "full", otherwise 'unsupported style preset: <preset>' is returned at options.go:3577.

Solutions

1. Use a supported preset name or the 'full[:border]' form
2. Check fzf --help for the list of valid presets
3. Verify spelling and the colon separator (e.g. --style=full:rounded)

Example fix

# before
fzf --style=compact
# after
fzf --style=full:rounded

// Shell: whitelist presets
presets='default minimal full'
case "$style" in default|minimal|full|full:*) ;; *) style='default' ;; esac
exec fzf --style="$style"

When it happens

Trigger: Passing --style with an unknown name, e.g. --style=compact or --style=fullx, or misspelling 'full' (e.g. --style=ful:rounded). tokens[0] != "full" triggers the error.

Common situations: Typos in preset names; expecting presets from other tools or older/newer fzf versions; forgetting that the colon-border suffix only applies to the 'full' preset.
