Functions ¶
func If ¶
If is a ternary function for returning a value if a condition is true and another if false.
Example ¶
package main
import (
"fmt"
"github.com/SharkByteSoftware/go-snk/conditional"
)
func main() {
score := 85
label := conditional.If(score >= 60, "pass", "fail")
fmt.Println(label)
}
Output: pass
func IfCall ¶
func IfCall(cond bool, trueFunc, falseFunc func())
IfCall is a ternary function for calling a function if a condition is true and calling another if false.
Example ¶
package main
import (
"fmt"
"github.com/SharkByteSoftware/go-snk/conditional"
)
func main() {
conditional.IfCall(
true,
func() { fmt.Println("welcome back") },
func() { fmt.Println("please log in") },
)
}
Output: welcome back
func IfCallReturn ¶
IfCallReturn is a ternary function for calling a function if a condition is true and calling another if false and returns the result.
Example ¶
package main
import (
"fmt"
"github.com/SharkByteSoftware/go-snk/conditional"
)
func main() {
limit := conditional.IfCallReturn(
false,
func() int { return 100 },
func() int { return 10 },
)
fmt.Println(limit)
}
Output: 10
func IfNotNil ¶
func IfNotNil[T any](x *T, callee func())
IfNotNil calls a function if x is not nil.
Example ¶
package main
import (
"fmt"
"github.com/SharkByteSoftware/go-snk/conditional"
)
func main() {
name := "Alice"
conditional.IfNotNil(&name, func() {
fmt.Println("name is set")
})
}
Output: name is set
func Switch ¶ added in v1.2.2
func Switch[K comparable, V any](key K, cases map[K]V, fallback V) V
Switch returns the value associated with key in the cases map. If the key is not present, fallback is returned. It is useful for concise value lookup that would otherwise require a switch statement or repeated if/else chains.
Example ¶
package main
import (
"fmt"
"github.com/SharkByteSoftware/go-snk/conditional"
)
func main() {
status := 2
label := conditional.Switch(status, map[int]string{
1: "active",
2: "inactive",
3: "pending",
}, "unknown")
fmt.Println(label)
}
Output: inactive
Example (Fallback) ¶
package main
import (
"fmt"
"github.com/SharkByteSoftware/go-snk/conditional"
)
func main() {
status := 99
label := conditional.Switch(status, map[int]string{
1: "active",
2: "inactive",
3: "pending",
}, "unknown")
fmt.Println(label)
}
Output: unknown
