shomali11 / util Goto Github PK

Hello @shomali11,
It's very useful util that you have written, but in this case how you are handling errors. For example, if func1 breaks I don't wanna execute the other two func.

func1 := func() {
    f(0)
}

func2 = func() {
    f(1)
}

func3 = func() {
    f(2)
}

Parallelize(func1, func2, func3)

Inspired by a comment on this SO about string-reversal in Python:

For example, "🇬🇧"[::-1] yields "🇧🇬".

I thought I'd try your Reverse() func:

assert.Equal(t, Reverse("🇬🇧"), "🇬🇧")

and I got:

Error Trace:	xstrings_test.go:86
    
Error:      	Not equal: 
    
                expected: "🇧🇬"
    
                actual  : "🇬🇧"
    
Test:       	TestReverse

Flags are special in that they are specific ordering of two letters to designate the ISO-3166 country code, which for some systems and fonts is rendered as that country's flag¹:

Regional indicator symbols
These characters can be used in pairs to represent regional
codes. In some emoji implementations, certain pairs may be
recognized and displayed by alternate means; for instance,
an implementation might recognize F + R and display this
combination with a symbol representing the flag of France

I only see the IfThenElse, and this only take 3 arguments.
So I made this:

func ifThenElseIfElse(args ...interface{}) interface{} {
	if len(args) < 3 || len(args)%2 == 0 {
		panic("Need to pass at least 3 arguments, and argument length must be an odd number")
	} else {
		for i, value := range args {
			if i%2 == 0 && len(args) > 3 { //loop even index only
				if reflect.ValueOf(args[i]).Kind() != reflect.Bool {
					if i != len(args)-1 {
						panic(fmt.Sprintf("Value at param %d need to be a boolean!", i+1))
					}
				} else {
					if value.(bool) {
						return args[i+1]
					}
				}
			}
		}
	}
	return args[len(args)-1]
}

With that, we can do a complex one like:

if (1 < 2) ? 1 : (2 > 3) ? 2 : (3 > 3) ? 3 : 4

I'm new to Golang, so that function might look like a mess, but you got the idea.
Thanks
