Functions

func Eq

func Eq(a bool, b bool) bool

Check if antecedent ⇔ consequent (a ⇔ b).

a: antecedent

b: consequent

func Imply

func Imply(a bool, b bool) bool

Check if antecedent ⇒ consequent (a ⇒ b).

a: antecedent

b: consequent

func Neq

func Neq(a bool, b bool) bool

Check if antecedent ⇎ consequent (a ⇎ b).

a: antecedent

b: consequent

func Nimply

func Nimply(a bool, b bool) bool

Check if antecedent ⇏ consequent (a ⇏ b).

a: antecedent

b: consequent

func Not

func Not(a bool) bool

Check if value is false.

a: a boolean

func Parse

func Parse(s string) bool

Convert string to boolean.

s: a string

Example (False1)

fmt.Println(Parse("not true"))

Output:

false

Example (False2)

fmt.Println(Parse("inactive"))

Output:

false

Example (False3)

fmt.Println(Parse("disabled"))

Output:

false

Example (True1)

fmt.Println(Parse("1"))

Output:

true

Example (True2)

fmt.Println(Parse("truthy"))

Output:

true

Example (True3)

fmt.Println(Parse("not off"))

Output:

true
