在GDB中打印复杂Go结构

我需要一些关于使用GDB+Python扩展for Go的帮助

我试图研究的struct LogQuery的组成如下：

   LogQuery (struct)
     CommonCmd (struct)
         Context (struct)
            out
            Globs
         flagHelp
         ...
      flagLog
      ...


Breakpoint 3, acme/subcmds.CmdObj (context=..., cmdName="log_query", noname=
    void) at /nobackup/git/goacme/src/acme/subcmds/cmder.go:32
32   cmd = NewLogQuery(context) //debugger
(gdb) s
acme/subcmds.NewLogQuery (context=..., noname=void)
    at /nobackup/git/goacme/src/acme/subcmds/log_query.go:29
29  func NewLogQuery(context context.Context) LogQuery {
(gdb) n
30   obj := LogQuery{NewCommonCmd(context), "", "", "", "", 0, "", ""}
(gdb) 
31   return obj

1-在构造函数内部打印对象（obj）是可行的。但我如何看待“obj.Globs”

(gdb) p obj
$8 = {acme/subcmds.CommonCmd = {acme/context.Context = {out = 0, Globs = 
    0xf840050140}, FlagArgs = "", flagDebug = "", flagHelp = false, 
    flagOutput = "", flagVerbose = false, CmdName = "", debug = 0x0}, 
  flagColl = "", flagData = "", flagDb = "", flagHost = "", flagLimit = 0, 
  flagLog = "", flagQuery = ""}

返回给来电者

(gdb) n
acme/subcmds.CmdObj (context=..., cmdName="log_query", noname=void)
    at /nobackup/git/goacme/src/acme/subcmds/cmder.go:40
40   if cmdName == "acme" {

在这里，我看到了对象的类型，但似乎看不到其中的任何内容

(gdb) p cmd
$9 = "(subcmds.LogQuery)0xf840052b60"

(gdb) p $dtype(cmd)
$2 = (struct cmds.Add *) 0xf840034210

(gdb) p cmd->Globs
A syntax error in expression, near `>Globs'.

(gdb) p cmd.Globs
There is no member named Globs.

确切地说，我们如何重现您的问题？您是否在gdb中加载了go/src/pkg/runtime/runtime-gdb.py？
