🎉 Released a new version 1.0.5! 🎉

What's New?

nullableBoolean.whatIfElse {
  log("nullableBoolean is not null and false")
}

• Added whatIfAnd, whatIfOr.
  An expression for invoking whatIf lambda when the target boolean is true and/or a predicate receiver is true.

nullableBoolean.whatIfAnd(predicate) {
  log("nullableBoolean is true and the predicate is also true")
}

nullableBoolean.whatIfOr(predicate) {
  log("nullableBoolean is true or the predicate is true")
}

WhatIf for Android fragment

• whatIfNotNullContext.
  An expression for invoking whatIf lambda when the Context is not null.

class WhatIfFragment : Fragment() {

  override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
    super.onViewCreated(view, savedInstanceState)

    whatIfNotNullContext {
      Toast.makeText(it, "context is not null!", Toast.LENGTH_SHORT).show()
    }
  }
}

• whatIfNotNullArguments

An expression for invoking whatIf when the Fragment.getArguments is not null.

whatIfNotNullArguments {
  it.getString("name").whatIfNotNull {
    log("my name is $it")
  }
}

• whatIfNotNullActivity

whatIfNotNullActivity { activity ->
  activity.supportFragmentManager.addOnBackStackChangedListener {
    // .. //
  }
}

1.0.4

Released version 1.0.4.

WhatIfHasExtras

An expression for invoking whatIf lambda when the Activity's intent extras is not null and not empty.

var foo: String? = null
this@MainActivity.whatIfHasExtras {
  foo = "${it.getString("foo")}"
}

And we can handle the null case.

this@MainActivity.whatIfHasExtras(
   whatIf = { foo = "${it.getString("foo")}" },
   whatIfNot = { log("intent extras is null or empty.") }
)

1.0.3

Released version 1.0.3.

Implemented whatIfNotNullOrEmpty for string type.
We can execute a single lambda if the string is not null and not empty.

val nullableString: String? = "NotNullOrEmpty"
nullableString.whatIfNotNullOrEmpty { 
  log("$it is not null and not empty")
}

Or we can handle the null or empty case.

nullableString.whatIfNotNullOrEmpty(
  whatIf = { nullableString = it },
  whatIfNot = { nullableString = "NullOrEmpty" }
)

1.0.2

Version 1.0.2 is released.

Changed whatIfNotNullOrEmpty collections separated toList and Set.
In whatIfNotNullOrEmpty, whatIf lambda will receive not-null type collection type.

Implemented whatIfNotNullAs.
If the target is not null, the receiver will get a casted type.

var nullableIntList: MutableList<Int>? = null
nullableIntList.whatIfNotNullAs<List<Int>> {
  nullableInt = it.size
}

1.0.1

Version 1.0.1 is released.

Implemented below functionality extensions.

• whatIfNotNullOrEmpty for array type and collections.
