Contextual Mark Attachment

[mhd (Mohamed Elrayah Mustafa)]

Hello @Aida

It works when waw-ar carries a mark, but it doesn’t when waw-ar doesn’t carry marks.

[GeorgSeifert]

can you show what you have in the anchor context?

[mhd (Mohamed Elrayah Mustafa)]

lookupflag UseMarkFilteringSet [kasratan-ar kasra-ar]; [waw-ar waw-ar.fina] [kasratan-ar kasra-ar] *

[GeorgSeifert]

lookupflag UseMarkFilteringSet [kasratan-ar kasra-ar];
[waw-ar] [kasratan-ar kasra-ar] *;
[waw-ar] *

this should work.

[mhd (Mohamed Elrayah Mustafa)]

It doesn’t work. And a message appears when I export to test.

I had another look. And it needs to be:

lookupflag UseMarkFilteringSet [kasratan-ar kasra-ar];[waw-ar] [kasratan-ar kasra-ar] *;
lookupflag UseMarkFilteringSet [kasratan-ar kasra-ar];[waw-ar] *

Oh nice, does this mean we can have multiple contexts in one anchor now? Does each one need to start with its own filter set?

[GeorgSeifert]

Yes and yes.

Thanks, Georg. It works.

I need to understand more about OpenType Features — essentials to advanced. Are there any recommended articles or tutorial resources?.
