Is there a better way to do this?
You should use a 'join' method to make the intentions of your code clear and
to prepare for code reuse:
string htmlCardItemSeparated(string itemName, ArrayList<string> itemList,
string separator = ", ")
{
return itemList.is_empty ? "" :
@"<tr><td>$itemName</td><td>$(join(itemList,
separator))</td></tr>\n";
}
A 'join' method is most efficiently implemented with a StringBuilder:
string join(Iterable<string> strings, string separator = ", ") {
var builder = new StringBuilder();
var it = strings.iterator();
for (var has_next = it.first(); has_next; has_next = it.next()) {
builder.append(it.get());
if (it.has_next()) {
builder.append(separator);
}
}
return builder.str;
}
Alternatively you could use 'string.joinv', but then you would have to convert
your list into a null-terminated array first.
Best regards,
Frederik

Thanks. I'll have to look for documentation on StringBuilder.
