# Kotlin in SystemUI
Queue "it's happening" gif.
Kotlin is probably going to be a bit of a wild west for a while, but please
try to follow these guidelines as much as possible.
- No semi-colons: they are optional, we probably don't want them in the
future, so let's just not add them.
- No DSLs: sysui is complicated enough as is, let's not add more layers at
the moment.
- Only use extension functions for keeping complex code locality: Don't use
extension functions to add methods to android classes that you always wished
were there, instead add them directly to the class and save us the extension.
- inline, reified, and de-compisition can all be great things: just make sure
you know what they do and why you are using them.
