go-argcheck

Simple Go argument preconditions checker

This minimal library allows to embrace Fail Fast paradigm, by providing a set of functions to check preconditions and do validations on arguments. Whenever a precondition is not met, a panic will be thrown.

Usage

Just get it

$ go get github.com/raulbajales/go-argcheck/argcheck

And use it

import (
	"github.com/raulbajales/go-argcheck/argcheck"
	"fmt"
)

func calculateMonthlySalary(total int, numMonths int) int {
	argcheck.GreaterThanf(numMonths, 0, "numMonths must be positive and not zero, numMonths is %v", numMonths)
	return total / numMonths
}

func main() {
 	total := 50000
	numMonths := 0
	fmt.Printf("Total salary of %v in %v months, gives %v per month.", total, numMonths, calculateMonthlySalary(total, numMonths))
}
