Snippet arguments

A snippet can take parameters, so one declaration renders differently on each call. The parameters are ordinary Go — you name them in the {snippet …()} header and use them in the body.

The tag from the last lesson always reads todo. We can make it show a label passed at each call site instead.

Your turn

Give the snippet a string parameter and use it:

{snippet tag(label string)}<div class="tag">— {label} —</div>{/snippet}

{label} is a plain parameter, not a signal, so it does not need .Get(). Now pass a label at each call: {render tag("buy milk")} and {render tag("write tutorial")}.

Press Run; each tag shows its own text. Solve shows the finished version; Reset restores the start.
