Display column X of input without delimiter?

[MartyMcFlyInTheSky]

I've read that fzf delimiters somehow behave weird already, but I still can't wrap my head around it. For example in the following example I want to display only the first column in the display window:

    local tasks=$(cat << 'EOF'
List all files, ls -al
Show os information, cat /etc/os-release
Display current user, whoami
EOF
)
    local task=$(printf "%s\n" "$tasks" | fzf --delimiter=, --with-nth=1)

However, the comma seperator is always displayed as well:

  Display current user,
  Show os information,
▌ List all files,
  3/3
>

How can i omit it?

{1}. See:

fzf/man/man1/fzf.1

Lines 122 to 136 in bf77206

	.BI "\-\-with\-nth=" "N[,..] or TEMPLATE"
	Transform the presentation of each line using the field index expressions.
	For advanced transformation, you can provide a template containing field index
	expressions in curly braces. When you use a template, the trailing delimiter is
	stripped from each expression, giving you more control over the output.
	\fB{n}\fR in template evaluates to the zero-based ordinal index of the line.
	.RS
	e.g.
	# Single expression: drop the first field
	echo foo bar baz | fzf --with-nth 2..
	# Use template to rearrange fields
	echo foo,bar,baz | fzf --delimiter , --with-nth '{n},{1},{3},{2},{1..2}'

Perfect, that works! Thx!
