I am trying to implement language support plugin for a basic language. I am following jetbrains's tutorial for simple language support (.properties file support basically) and on the side I have rust plugin for reference. However the complexity gap between them is huge so some questions are hard to find answers to from both sources.
Here is my question: What is the best way to allow spaces between tokens which DO NOT require spaces, however force spacing between tokens which do?
i.e. class Foo{ <- here first space is mandatory, but the second one (before '{' symbol) can be ommited.
