I’d really like to use the JavaScript Ligation Set of the Iosevka font, but I’ve not been able to find a way to specify it in font_options. The instructions appear to suggest that this could work:
font_options: [ "no_calt", "JSPT" ]
but no joy. Is it possible at all?
ST supports a subset of open type font-options, only, which include the options listed in font_options's comment. “JSTP” is not supported, atm.
There are some feature requests to support certain open type features such as:
Thanks—will chime in there. I tried building a custom version of Iosevka following the instructions to inherit the JavaScript ligation, but didn’t get anywhere sadly—I didn’t get any ligatures at all then :(.
Just wanted to add, in case it helps anyone else, I was able to use the basic Iosevka Fixed font and Ligaturizer to get exactly what I was after. I’m sure there are some bits compromised, but FiraCode was my previous preferred font, so this gives an almost ideal solution for me.
