Kotlin Rules

4 spaces for indentation
No semicolons (unless used to separate multiple statements on the same line)
No wildcard / unused imports
No consecutive blank lines
No blank lines before }
No trailing whitespaces
No Unit returns (fun fn {} instead of fun fn: Unit {})
No empty ({}) class bodies
No spaces around range (..) operator
No newline before (binary) + & -, *, /, %, &&, ||
When wrapping chained calls ., ?. and ?: should be placed on the next line
When a line is broken at an assignment (=) operator the break comes after the symbol
When class/function signature doesn't fit on a single line, each parameter must be on a separate line
Consistent string templates ($v instead of ${v}, ${p.v} instead of ${p.v.toString()})
Consistent order of modifiers
Consistent spacing after keywords, commas; around colons, curly braces, parens, infix operators, comments, etc
