Function serverURLEnumKeys

pkg/codegen/server_urls.go:186–200

serverURLEnumKeys returns deterministic identifier suffixes for each enum value of `v`, in `v.Enum` order. Each suffix is just the value with its first character upper-cased — matching what the previous template-only path produced for happy-path specs (` `), so adopters with

(v *openapi3.ServerVariable)

// correctness improvement, not a naming change for any spec that
// actually compiled before.
func serverURLEnumKeys(v *openapi3.ServerVariable) []string {
	keys := make([]string, len(v.Enum))
	seen := make(map[string]int, len(v.Enum))
	for i, val := range v.Enum {
		base := UppercaseFirstCharacter(val)
		if n, dup := seen[base]; dup {
			keys[i] = base + strconv.Itoa(n)
			seen[base] = n + 1
		} else {
			keys[i] = base
			seen[base] = 1
		}
	}
	return keys
}

// serverURLEnumValues returns the EnumValues map handed to GenerateEnums
// for variable `v`: key is the deduplicated identifier suffix from
