Overview ¶
Package condition contains some functions for conditional judgment. eg. And, Or, TernaryOperator ... The implementation of this package refers to the implementation of carlmjohnson's truthy package, you may find more useful information in truthy(https://github.com/carlmjohnson/truthy), thanks carlmjohnson.

Functions ¶
func And ¶
And returns true if both a and b are truthy. Play: https://go.dev/play/p/W1SSUmt6pvr
Example ¶
result1 := And(0, 1) result2 := And(0, "") result3 := And(0, "0") result4 := And(1, "0") fmt.Println(result1) fmt.Println(result2) fmt.Println(result3) fmt.Println(result4)
Output: false false false true
func Bool ¶
Bool returns the truthy value of anything. If the value's type has a Bool() bool method, the method is called and returned. If the type has an IsZero() bool method, the opposite value is returned. Slices and maps are truthy if they have a length greater than zero. All other types are truthy if they are not their zero value. Play: https://go.dev/play/p/ETzeDJRSvhm
Example ¶
// bool
result1 := Bool(false)
result2 := Bool(true)
fmt.Println(result1)
fmt.Println(result2)
// integer
result3 := Bool(0)
result4 := Bool(1)
fmt.Println(result3)
fmt.Println(result4)
// string
result5 := Bool("")
result6 := Bool(" ")
fmt.Println(result5)
fmt.Println(result6)
// slice
var nums = []int{}
result7 := Bool(nums)
nums = append(nums, 1, 2)
result8 := Bool(nums)
fmt.Println(result7)
fmt.Println(result8)
Output: false true false true false true false true
func Nand ¶
Nand returns false if both a and b are truthy. Play: https://go.dev/play/p/vSRMLxLIbq8
Example ¶
result1 := Nand(0, 0) result2 := Nand(1, 0) result3 := Nand(0, 1) result4 := Nand(1, 1) fmt.Println(result1) fmt.Println(result2) fmt.Println(result3) fmt.Println(result4)
Output: true true true false
func Nor ¶
Nor returns true if neither a nor b is truthy. Play: https://go.dev/play/p/g2j08F_zZky
Example ¶
result1 := Nor(0, 0) result2 := Nor(1, 1) result3 := Nor(0, 1) result4 := Nor(1, 0) fmt.Println(result1) fmt.Println(result2) fmt.Println(result3) fmt.Println(result4)
Output: true false false false
func Or ¶
Or returns false if neither a nor b is truthy. Play: https://go.dev/play/p/UlQTxHaeEkq
Example ¶
result1 := Or(0, "") result2 := Or(0, 1) result3 := Or(0, "0") result4 := Or(1, "0") fmt.Println(result1) fmt.Println(result2) fmt.Println(result3) fmt.Println(result4)
Output: false true true true
func TernaryOperator ¶
func TernaryOperator[T, U any](isTrue T, ifValue U, elseValue U) U
TernaryOperator checks the value of param `isTrue`, if true return ifValue else return elseValue. Play: https://go.dev/play/p/ElllPZY0guT
Example ¶
conditionTrue := 2 > 1 result1 := TernaryOperator(conditionTrue, 0, 1) fmt.Println(result1) conditionFalse := 2 > 3 result2 := TernaryOperator(conditionFalse, 0, 1) fmt.Println(result2)
Output: 0 1
func Xnor ¶
Xnor returns true if both a and b or neither a nor b are truthy. Play: https://go.dev/play/p/OuDB9g51643
Example ¶
result1 := Xnor(0, 0) result2 := Xnor(1, 1) result3 := Xnor(0, 1) result4 := Xnor(1, 0) fmt.Println(result1) fmt.Println(result2) fmt.Println(result3) fmt.Println(result4)
Output: true true false false
func Xor ¶
Xor returns true if a or b but not both is truthy. Play: https://go.dev/play/p/gObZrW7ZbG8
Example ¶
result1 := Xor(0, 0) result2 := Xor(1, 1) result3 := Xor(0, 1) result4 := Xor(1, 0) fmt.Println(result1) fmt.Println(result2) fmt.Println(result3) fmt.Println(result4)
Output: false false true true
