求推荐一个golang下使用配置文件的库，要求能保留注释？-灵析社区

我也找过，目前只发现一个办法。像是 go-yaml 这个库提供了 `yaml.Node` 结构，`Marshal`/`Unmarshal` 到这个结构可以保留注释信息。 package main import ( "log" "strings" yaml "gopkg.in/yaml.v3" ) func main() { var node yaml.Node data := []byte(strings.TrimSpace(` block1: # the comment map: key1: a key2: b block2: hi: there `)) log.Printf("INPUT:\n %s", data) if err := yaml.Unmarshal(data, &node); err != nil { log.Fatalf("Unmarshalling failed %s", err) } results, err := yaml.Marshal(node.Content[0]) if err != nil { log.Fatalf("Marshalling failed %s", err) } log.Printf("RESULT:\n %s", results) } 输出 2009/11/10 23:00:00 INPUT: block1: # the comment map: key1: a key2: b block2: hi: there 2009/11/10 23:00:00 RESULT: block1: # the comment map: key1: a key2: b block2: hi: there
