bash自動完成使用codegangsta cli框架[https://github.com/codegangsta/cli]

Question

我是golang的新手，我正在使用代碼gangsta cli框架[https://github.com/codegangsta/cli]來開發命令行應用程序。我正試圖爲這些命令的標誌實現自動完成功能，但看起來它不像預期的那樣工作。有沒有人試圖使用這個框架來實現這個功能？

這裏是我的部分代碼：

package main 

import (
    "fmt" 
    "os" 

    "github.com/codegangsta/cli" 
) 

func main() { 
    app := cli.NewApp() 
    app.Name = "greet" 
    app.Usage = "sample command-line app by greet" 
    app.Author = "abc" 
    app.Email = "xyz@aaa.com" 
    app.EnableBashCompletion = true 
    app.Commands = []cli.Command{ 
     { 
      Name:  "read", 
      ShortName: "r", 
      Usage:  "read something", 
      Subcommands: []cli.Command{ 
       { 
        Name: "articles", 
        Usage: "read articles", 
        Action: readArticles, 
       }, 

       { 
        Name: "tweets", 
        Usage: "read Tweets", 
        Flags: []cli.Flag{ 
         cli.StringFlag{ 

          Name: "account", 
          Value: "SomeThing", 
          Usage: "name of Twitter account", 
         }, 
        }, 
        Action: readTwitter, 
       }, 
      }, 
     }, 
    } 
    app.Run(os.Args) 
} 

func readArticles(ctx *cli.Context) { 
    fmt.Println("Go to http://www.google.com to read articles!") 
} 

func readTwitter(ctx *cli.Context) { 
    fmt.Printf("Go to https://twitter.com/%s to read tweets!", ctx.String("account")) 
} 

這裏是預期輸出：

./greet閱讀鳴叫--a [TAB] [TAB]不起作用。

我會讀一讀cli repo自述文件的這一部分。
