英文:
Recursively generate golang cobra --help text?
问题
如果我有一个由Cobra管理的Golang应用程序，我可以调用mycommand --help来查看顶级帮助和命令列表，mycommand cmd1 --help来查看第一个命令的帮助信息，等等。
在使用Cobra库的情况下，有没有一种方法可以递归地一次性打印出所有的命令、标志和帮助文本？

英文:
If I have a cobra-managed golang application, I can invoke mycommand --help to see the top level help and list of commands, mycommand cmd1 --help to see the same for the first command, etc.
Is there a way using the cobra library to recursively print all the commands, flags, and help text in one pass?

我能够编写一些代码。这只是一个简单的递归函数，通过命令名称过滤掉一些噪音（例如，我跳过自动生成的帮助和bash完成命令）。
var dumpAllHelp = "dump-all-help"var recHelpCmd = &cobra.Command{Use: dumpAllHelp,Short: "dump all help texts",Long: "dump all help texts",Run: func(_ *cobra.Command, _ []string) {dumpHelp(rootCmd, true)},}func dumpHelp(c *cobra.Command, root bool) {if !root {fmt.Println("")fmt.Println("========================================================")fmt.Println("")}c.Help()for _, child := range c.Commands() {if child.Hidden || child.Name() == "completion" || child.Name() == "help" || child.Name() == dumpAllHelp {continue}dumpHelp(child, false)}}func init() {rootCmd.AddCommand(recHelpCmd)}
希望这对你有帮助！

I was able to hack something up. This is just a simple recursive function that filters out some noise by command name (e.g I skip over autogenerated help and bash completion commands)
var dumpAllHelp = "dump-all-help"var recHelpCmd = &cobra.Command{Use: dumpAllHelp,Short: "dump all help texts",Long: "dump all help texts",Run: func(_ *cobra.Command, _ []string) {dumpHelp(rootCmd, true)},}func dumpHelp(c *cobra.Command, root bool) {if !root {fmt.Println("")fmt.Println("========================================================")fmt.Println("")}c.Help()for _, child := range c.Commands() {if child.Hidden || child.Name() == "completion" || child.Name() == "help" || child.Name() == dumpAllHelp {continue}dumpHelp(child, false)}}func init() {rootCmd.AddCommand(recHelpCmd)}
