Issue Adding Fast Font

[rogueaskywalker]

I've been working on adding the fast font feature to the bookerly font. I've gotten up to the point where I add the calt coding but after applying it, the font does not show the fast font feature in preview. I'm not sure what I did wrong.

Here is a link to the font so far. I've only modified regular just so that I can figure out where in the code it is wrong

Hi,
from what I understand realting to your description and screenshot it looks all quite good.
The code itself definetely works, I can assure you that.

That means it is probably an issue with the software, like a missing setting.
For example in FontForge you have to tick an extra checkbox to activate the Font-Features... (see circled box in below screenshot)

If it still does not work:

• Have you tried other projects to see any kind of change in the preview panel?
• Have you tried exporting the font and test the features in another software like MS-Word other other tools?
