I’m wondering if there is some mechanism by which the custom GPOS lookups/feature code can be manually ordered.
I have a use case where i’m using anchors to position a below mark, but in come contexts that below mark needs to be lowered a bit. Instead of using two anchors, i’m using a single adjustment lookup to simplify things. However, because this single adjustment lookup is included in a ‘manual’ dist feature it occurs before the automatic abvm and thus is superseded by the latter.
I remember reading about including a custom comment before the start of the lookup either here on the forum or in the handbook but i’m unable to locate it.
I also found the thread where I had requested this functionality for the Indic mark positioning features. I tried this now and see that it’s not implemented yet (alas not in the stable release).
@mekkablue I would love to, but i’m not generating the final fonts. The Glyphs source goes to the client (who use 1075), so we both need the output to be identical.
You should have received source files, a script and applet from the client that generates a GPOS source and loads all tables into the generated instances.
