JetBrains recently released a new typeface for developers and I wanted to give it a try. I switched to JetBrains Mono in my two primary editors, Xcode and Sublime Text. Much to my surprise, I really enjoyed it. I think it is a great typeface. But I quickly discovered that I hate ligatures.
There was no way (that I could find) to select JetBrains Mono in Xcode and disable ligatures. If anyone knows how to do that, please let me know. For now, I will stick with SF Mono in Xcode.
In Sublime Text, you can add the following options to your preferences file to disable ligatures.
"font_face": "JetBrains Mono", "font_options": ["no_liga", "no_clig", "no_calt"],
And now your eyes can rest. If you prefer ligatures, don’t @ me.
Update 26 February 2020
There is an open issue on GitHub discussing providing a version without ligatures.
