Spinner keeps erasing my line

[cflewis]

Hi there,
I am having a problem using the spinner correctly :(

Here is my code:

func printStatus(s string) func() {
        spin := spinner.New(spinner.CharSets[14], 1*time.Second)
        spin.Color("fgBlack")
        spin.Prefix = s
        spin.Start()
        time.Sleep(4 * time.Second)

        return func() {
                spin.Stop()
                fmt.Printf("\n")
        }
}

When the spinner is executing, it starts backspacing my lines:
e.g.

Creating cust
Creating credentia⠙

(from "Creating customer" and "Creating credentials")

Every spin iteration moves back one more. In Bash this appears to work correctly.

I could get over this by using Prefix, but when the spinner ends it deletes the whole line, which isn't what I want. I want the output to remain.

What can I do here?

Thank you!

I got around the eating, so I'm going to close. Here's what I did:

func printStatus(s string) func() {
        spin := spinner.New(spinner.CharSets[26], 1*time.Second)
        spin.Prefix = s
        spin.Start()
        time.Sleep(4 * time.Second)

        return func() {
                spin.Stop()
                fmt.Println(s + "... done")
        }
}

This is interesting. Thank you very much for the follow up. Do you know if this is Fish specific or fish and zsh specific?

I misspoke (misstyped?) it wasn't limited to any shell, it was every shell, including Bash.

I am sure I Am Holding It Wrong but I am not sure exactly how. I am happy with what I think is a workaround, but maybe it's not a workaround and how it should be done?
