I propose the following API, which is passed an instance of WFL's UserAgent object and returns a boolean.

  enabled: function(userAgent) {
    // No fonts in IE
    return userAgent.getName() != 'MSIE';

This should handle all the cases I can think of.


rcarver commented Jul 15, 2010

Logically, where should this sit? If you define 'enabled', does it:

  1. Only get called if userAgent.isSupportingWebFont() returns true?
  2. Get called regardless of what userAgent.isSupportingWebFont() returns?

At first I was leaning toward (1), but now I think (2) is better because it gives users an option when new browsers come out that UserAgent may not correctly identify.

I would vote for case number 2. I think it sits in front of the whole webfontloader, as there are some platforms people don't want to use webfonts with, at all.

There seem to be two big use cases, right?

  1. I want to enable a useragent that WFL isn't considering supported.
  2. I want to disable a particular useragent that WFL supports.

What about override instead of enabled?
That seems to more clearly imply that this method is optional and alters default behavior.


rcarver commented Jul 16, 2010

1 & 2: yes I think that covers it. I'm sold on the logic to allow both.

override is good. Is it clear enough what override overrides?

Ryan I know we talked about this yesterday but what do we do in the Typekit module when the user overrides an unsupported browser?
