comment not working for docgen

[keith6014]

I have some code like this

package main

// Ping is a simple function with some comments

func main() {                                                                                                                                                                                  
        r := chi.NewRouter()                                                                                                                                                                   
        r.Get("/ping", ping)                                                                                                                                                                   
        fmt.Printf("%v\n", docgen.JSONRoutesDoc(r))                                                                                                                                            
}           

the output is this

{
  "router": {
    "middlewares": [],
    "routes": {
      "/ping": {
        "handlers": {
          "GET": {
            "middlewares": [],
            "method": "GET",
            "pkg": "",
            "func": "main.ping",
            "comment": "",
            "file": "/mnt/cmd/go-chi/main.go",
            "line": 12
          }
        }
      }
    }
  }
}

I would of expected comment to be filled with "Ping is a simple function with some comments"

any news?

@keith6014 @fr3fou, in the example, you have to make the ping function exportable by rename it to Ping then you should see the comment in json.

@pkieltyka you can close this.
