I want to make my own coding font with layout features. I don’t like ligatures for operators etc., but tried to add them first to my font to see if they work in general.
I just can’t get it to work. Is there anything special the font has to do to activate ligatures and other OpenType layout features?
I’ve been working on font engineering for quite a while, so the fonts should be fine. Ligatures are active in Fira Code and Space Mono, which use different techniques (calt
feature vs. liga
feature), so it should be no big deal to get working layout features, but they just are not applied in my font. Neither on Windows 10 nor MacOS 10.12, neither in OTF nor TTF files. The only difference is that my font is not monospaced while Fira Code and Space Mono are. I’m using build 3156.
Any ideas or hints?
