Helpers cannot have negative integer parametres?

[raix]

Hi, seems a helper cant recieve negative integer, can you verify?
Negative Integer parsed as id?

Only place I can see something supporting my issue is:
handlebars.js / src / handlebars.l ln 45:

<mu>[0-9]+/[}\s]

Not sure if following would work: (not tested)

<mu>-?[0-9]+/[}\s]

Thanks

Confirmed, this is a bug. Failing test:

test("negative number literals work", function() {
  var string   = 'Message: {{hello -12}}';
  var hash     = {};
  var helpers  = {hello: function(times) {
    if(typeof times !== 'number') { times = "NaN"; }
    return "Hello " + times + " times";
  }};
  shouldCompileTo(string, [hash, helpers], "Message: Hello world -12 times", "template with a simple String literal");
});

By the way, I still find that handlebars doesn't support negative integer as hash. for example {{#ifgreater a compare=-1}}, the "compare" is undefined from helper.
