Fails with generic function - "Error formatting source: exit status 2"

[karatekaneen]

When trying to run golines on a file with a generic function it fails with "Error formatting source: exit status 2".

Environment OS: OSX 12.6.3 - Monterey Version: 0.11 Go: 1.20.1

To reproduce

package main

func find[T any](s []T, predicate func(T) bool) (T, bool) {
    for _, item := range s {
        if predicate(item) {
            return item, true
        }
    }
    return s[0], false
}

func main() {
    aVeryLongVariableNameThatWillTrigger := []string{"hello", "world", "hope", "you", "all", "are", "doing", "well"}
    find(aVeryLongVariableNameThatWillTrigger, func(superLongNameAgain string) bool { return superLongNameAgain == "you" })
}

I can't reproduce that here using that file. (I'm on the same version of macOS, with the same versions of golines and go as you.) My guess is that your problem is related to goimports being out of date. Take a look at these two old issues.
