Method Unique

codegen/scope.go:56–77

Unique returns a unique name for the given name. A suffix is appended to the name if given name is not unique. If suffixed name is still not unique, a counter value is added to the suffixed name until unique.

(name string, suffix ...string)

// name if given name is not unique. If suffixed name is still not unique, a
// counter value is added to the suffixed name until unique.
func (s *NameScope) Unique(name string, suffix ...string) string {
	c, ok := s.counts[name]
	if !ok {
		s.counts[name]++
		return name
	}
	if len(suffix) > 0 {
		name += suffix[0]
		c, ok = s.counts[name]
		if !ok {
			s.counts[name]++
			return name
		}
	}
	for i := c; ; i++ {
		ret := name + strconv.Itoa(i+1)
		if _, ok := s.counts[ret]; !ok {
			s.counts[ret]++
			return ret
		}
	}
}

// PeekUnique returns the name that Unique would return for the same inputs,
// without mutating the scope.
