if input null, error input.length , input.substring lines. should check, if not null.

@helper truncate(string input, int length) { if(input == null) { // } else { if (input.length <= length) { @input; } else { @input.substring(0,length)@:... } } }

edit (after comment)

you can use:

input = regex.replace(input , "<.*?>", string.empty);

note: html.raw returns markup not html encoded.
