go-prompt

A library for building powerful interactive prompts inspired by python-prompt-toolkit,
making it easier to build cross-platform command line tools using Go.
package main
import (
"fmt"
"git.tcp.direct/tcp.direct/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)
}
