Separate Implementation in own files in same package
问题
我正在尝试使用Go语言进行编程。所以我发明了一个小项目，并希望构建一个带有不同命令的小型控制台应用程序。
我找到了codegangsta/cli并尝试了示例代码。
package main
import (
"os"
"github.com/codegangsta/cli"
)
func main() {
app := cli.NewApp()
app.Commands = []cli.Command{
{
Name: "add",
Usage: "add a task to the list",
Action: func(c *cli.Context) {
println("added task:", c.Args().First())
},
},
{
Name: "complete",
Usage: "complete a task on the list",
Action: func(c *cli.Context) {
println("completed task:", c.Args().First())
},
},
}
app.Run(os.Args)
}
现在我想将命令放在Commands数组中的单独文件中，并且只引用它们。
我该如何实现这一点？
谢谢您的建议。

I am try to get hands dirty with golang. So I invented a small project and want do build a small console app with different commands.
I found codegangsta/cli and tried the example.
package main
import (
"os"
"github.com/codegangsta/cli"
)
func main() {
app := cli.NewApp()
app.Commands = []cli.Command{
{
Name: "add",
Usage: "add a task to the list",
Action: func(c *cli.Context) {
println("added task: ", c.Args().First())
},
},
{
Name: "complete",
Usage: "complete a task on the list",
Action: func(c *cli.Context) {
println("completed task: ", c.Args().First())
},
},
}
app.Run(os.Args)
}
Now I want to put the commands in Commands-array in separate files and only reference them.
How can I achieve this?
Thanks for some advice.

以下是将文件拆分的一种方法：
在 main.go 文件中：
package main
import (
"os"
"github.com/codegangsta/cli"
)
func main() {
app := cli.NewApp()
app.Commands = []cli.Command{
addCommand,
completeCommand,
}
app.Run(os.Args)
}
在 commands.go 文件中编写：
package main
import (
"github.com/codegangsta/cli"
)
var addCommand = cli.Command{
Name: "add",
Usage: "add a task to the list",
Action: func(c *cli.Context) {
println("added task: ", c.Args().First())
},
}
var completeCommand = cli.Command{
Name: "complete",
Usage: "complete a task on the list",
Action: func(c *cli.Context) {
println("completed task: ", c.Args().First())
},
}
希望对你有帮助！

Here's one way of several ways to split the file up:
In file main.go:
package main
import (
"os"
"github.com/codegangsta/cli"
)
func main() {
app := cli.NewApp()
app.Commands = []cli.Command{
addCommand,
completeCommand,
}
app.Run(os.Args)
}
In file comamnds.go write:
package main
import (
"github.com/codegangsta/cli"
)
var addCommand = cli.Command{
Name: "add",
Usage: "add a task to the list",
Action: func(c *cli.Context) {
println("added task: ", c.Args().First())
},
}
var completeCommand cli.Command{
Name: "complete",
Usage: "complete a task on the list",
Action: func(c *cli.Context) {
println("completed task: ", c.Args().First())
},
}
