Helpers cannot have decimal parameters

[kayleg]

Passing a float to a helper is parsed as INTEGER.ID which causes a parse error.

Possible to change INTEGER to NUMBER and have the following expression or just add new NUMBER type?

<mu>-?\.?[0-9]+(\.[0-9]*)?/[}\s]

See gist for example and qunit test: https://gist.github.com/kayleg/5215127

The way you're compensating for the .X format allows for a .X.X format to pass the expression.

-?([0-9]*\.)?[0-9]+ would solve that but require you to have a digit after the decimal if you had one.

otherwise it gets a little less concise:

-?(([0-9]*\.)?[0-9]+|[0-9]+(\.[0-9]*)?) would cover all cases.

[kayleg]

Good catch, didn't think about that case.

The first enforces a nicer format but the second is more compatible with JS. Just my 2 cents

Released in v2.0.0-alpha.1

I'm using handlebars 1.3, is there a way to overcome this problem? I use a helper called Math, and I want to pass it the value 3.6

This is not going to be backported to 1.x. You'll need to upgrade to 2.x if you need this feature. The 2.0.0 final release will be made shortly but the 2.0.0-beta.1 release is effectively the same.

@kpdecker thank you very much for your answer.

2.0.0 is out btw

[otmezger]

ok, I'll update it as soon as I have a time. I hope the update procedure is straightforward and easy :-)
