New Features:

• Support for Scala 3! 🥳🎉🎉🎉 (Finally 😅)
  • Requires 3.3.X or higher
  • Resolves issue #10

Misc:

• Upgraded to SBT 1.10.10
• Updated Github actions files
• Upgraded some other dependencies

• Fixed bug that would sometimes cause extraneous null checks on non-nullable values

New Features:

• Added isNull macro

Bug fixes:

• Fixed bug relating to the handling of implicit defs

• Fixes issue #9

• Upgraded sbt to 1.3.0
• Casting now won't cause the macro to crash
• Skips unnecessary null-checks on non-nullable intermediate results
• Macro now works with multi-arg methods
• Function calls are now flattened. e.g. In X(Y(a)) the result of Y(a) won't be null-checked, because null could be a valid input into a method or function.
• ?? macro is now more efficient and only checks the minimum number of expressions needed to find a non-null value. Before it would check all provided expressions.

Improved efficiency, by removing unnecessary conversion between primitive vals and Java boxes types.

Added support for var-args in ?? macro

Added support for scala 2.13

Added ?? macro for null coalescing.

Use:

case class Person(name: String)

val person = Person(null)

assert(??(person.name)("Bob") == "Bob")

val person2: Person = null
val person3 = Person("Sally")

assert(??(person.name,person2.name,person3.name)("No name") == "Sally")

• Added optional default for ? macro. Simply add the default as the second argument and that will be returned in the absent case. e.g:

case class Person(name: String)

val person: Person = null

assert(?(person.name,"") == "")
