Ligatures only show in some languages

[knh190]

I set up Fira Code for Sublime Text 3, but only some languages show ligatures, like plain text or Ruby.

It doesn’t work for some languages (Lua, Python):

As my language specific settings are empty, so they should inherit from default settings.

Are ligatures also language syntax specific?

Are ligatures also language syntax specific?

yes, see:

Dev Build 3145

With regards to ligatures, text is first tokenised within regards to the rules in the syntax definition, and then shaped. If text crosses token boundaries (i.e. has a different scope applied to it), then it won’t get transformed into a ligature. If you’re unsure, then change the current syntax to Plain Text, and the ligatures should show as expected.
