detekt-operator

Detekt style rules to prefer expressions over named functions for kotlin operators.

detekt-operator is a plugin for detekt that performs style checking for the use of named functions instead of their operator equivalents.

Currently Supported Operators

• Unary Operators
  • a.unaryPlus() -> +a
  • a.unaryMinus() -> -a
  • a.not() -> !a
  • a.inc() -> a++
  • a.dec() -> a--
• Arithmetic Operators
  • a.plus(b) -> a + b
  • a.minus(b) -> a - b
  • a.times(b) -> a * b
  • a.div(b) -> a / b
  • a.rem(b) -> a % b
  • a.rangeTo(b) -> a..b
• a.contains(b) -> b in a
• Index Accessor Operators
  • a.get(i) -> a[i]
  • a.set(i, j) -> a[i, j]
• a.invoke() -> a()
• Augmented Assignments
  • a.plusAssign(b) -> a += b
  • a.minusAssign(b) -> a -= b
  • a.timesAssign(b) -> a *= b
  • a.divAssign(b) -> a /= b
  • a.remAssign(b) -> a %= b
• Equality and Inequality Operators
  • a.equals(b) -> a == b
  • !a.equals(b) -> a != b
• Infix functions
• Comparison Operators
  • a.compareTo(b) -> a > b
  • a.compareTo(b) -> a < b
  • a.compareTo(b) -> a >= b
  • a.compareTo(b) -> a <= b
