|
|
|
```go
|
|
package main
|
|
|
|
import (
|
|
"fmt"
|
|
"github.com/c-bata/go-prompt"
|
|
)
|
|
|
|
func completer(d prompt.Document) []prompt.Suggest {
|
|
s := []prompt.Suggest{
|
|
{Text: "users", Description: "Store the username and age"},
|
|
{Text: "articles", Description: "Store the article text posted by user"},
|
|
{Text: "comments", Description: "Store the text commented to articles"},
|
|
}
|
|
return prompt.FilterHasPrefix(s, d.GetWordBeforeCursor(), true)
|
|
}
|
|
|
|
func main() {
|
|
fmt.Println("Please select table.")
|
|
t := prompt.Input("> ", completer)
|
|
fmt.Println("You selected " + t)
|
|
}
|
|
```
