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
