Some questions about making an Arabic font

What about feh_yeh-ar.loclFAR?

No, what that creates is
sub feh-ar yeh-ar by feh_yeh-ar.loclFAR;

But what I need is feh-ar yeh-farsi not feh-ar yeh-ar lookinf different when set in Persian.
The persian yeh is a different letter: yeh-ar is 064A (final form FEF2); and yeh-farsi is 06CC (final form FBFD).

I see, feh-ar_yeh-farsi is what you want. That autocreates the ligature code, too.

Yes, perfect, that is what I want!

Only, the feature code creates:
sub feh-ar yeh-farsi by feh-ar_yeh-farsi;
for it to work I need to change that manually to:
sub feh.ar.init yeh-farsi.fina by feh-ar_yeh-farsi;

Is there a way to make sure the feature does that already?
All the other ligatures for arabic that are in themselves isolated (start with an initial and end with a final form) do not need to carry this in their name.

That is an interesting case. Could you send me some screenshots or better the glyphs file to test with? (send it as DM or email).

Thank you!
I sent you an email, Georg.

Hi Georg,
did you have a look at the Farsi yeh-ligatures? Is there a way, to create them and have the feature code created automatically?

I fixed it.
