OperatorExtensions

Provides additional operators currently not supported in Swift:

• Logical boolean operators (AND, OR, NOT, IMPL, XOR, XNOR, NAND, NOR)
• Logical boolean assignment operators (&&=, ||=, ...)

Usage

Logical operators

• Conjuncition:
  true ∧ false (U+2227)
  true && false
and(true, false)

• Disjunction:
  true ∨ false (U+2228)
  true || false
or(true, false)

• Negation (NOT):
  ¬true (U+00AC)
  ~true
not(true)

• Implication (IMPL):
  false ⇒ true (U+21D2)
  false → true (U+2192)
  false ⊃ true (U+2283)
  impl(false, true)

• Exclusive disjunction (XOR):
  true ⊕ false (U+2295)
  true ⊻ false (U+22BB)
  true ^^ false

• Equality (XNOR)
  true ⇔ false (U+21D4)
  true ≡ false (U+2261)
  true ↔ false (U+2194)
  xor(true, false)

• Negated conjunction (NAND)
  true ↑ false (U+2191)
  true ⊼ false (U+22BC)
  nand(true, false)

• Negated disjunction (NOR)
  true ↓ false (U+2193)
  true ⊽ false (U+22BD)
  nor(true, false)

Logical assignment operators

You can use the same operators as in Logical operators section above.

var left = true

• Conjunction AND (&&=, &=, ∧=)
  left &&= false, left equals false

• Disjunction OR (||=, |=, ∨=)
  left ||= false, left equals true

• Implication IMPL (→=, ⇒=, ⊃=)
  left →= false, left equals false

• Exclusive disjunction XOR (^^=, ^=, ⊕=, ⊻=)
  left ^^= true, left equals false

• Equality XNOR (⇔=, ≡=, ↔=)
  left ⇔= true, left equals true

• Negated conjunction NAND (↑=, ⊼=)
  left ↑= true, left equals false

• Negated disjunction NOR (↓=, ⊽=)
  left ↓= false, left equals false
