在Go中构建交互式提示

库地址： github.com/c-bata/go-prompt

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)
}

以上代码运行后进入提示行，输入指令时将提示。也可以翻历史记录。

package main

import (
	"fmt"

	prompt "github.com/c-bata/go-prompt"
)

func completer(in 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"},
		{Text: "groups", Description: "Combine users with specific rules"},
	}
	return prompt.FilterHasPrefix(s, in.GetWordBeforeCursor(), true)
}

func main() {
	in := prompt.Input(">>> ", completer,
		prompt.OptionTitle("sql-prompt"),
		prompt.OptionHistory([]string{"SELECT * FROM users;"}),
		prompt.OptionPrefixTextColor(prompt.Yellow),
		prompt.OptionPreviewSuggestionTextColor(prompt.Blue),
		prompt.OptionSelectedSuggestionBGColor(prompt.LightGray),
		prompt.OptionSuggestionBGColor(prompt.DarkGray))
	fmt.Println("Your input: " + in)
}
