go如何实现定时任务

GoSublime是一款基于Go语言开发的Sublime Text 3插件，它提供了丰富的功能和扩展性，其中包括自动完成功能，本文将详细介绍如何使用GoSublime实现自动完成功能，并提供详细的技术介绍和代码示例。

一、自动完成简介

自动完成是一种编程辅助工具，它可以在编写代码时根据用户的输入内容，提供相关的建议和提示，从而帮助开发者更快地编写代码，GoSublime的自动完成功能基于Go语言的REPL环境实现，支持多种编程语言，如Go、Python、JavaScript等，通过安装GoSublime插件，用户可以在Sublime Text 3中轻松地使用自动完成功能。

二、安装GoSublime插件

1. 首先确保已经安装了Sublime Text 3,如果没有安装，可以访问官网()下载并安装。

2. 打开Sublime Text 3,点击菜单栏的`Preferences` > `Package Control`,这将打开Package Control界面。

3. 在Package Control界面的搜索框中输入`GoSublime`,找到对应的插件并点击安装按钮(一个带有绿色箭头的图标)。

4. 安装完成后，重启Sublime Text 3以激活插件。

三、配置GoSublime自动完成

1. 打开Sublime Text 3的用户设置文件，点击菜单栏的`Preferences` > `Browse Packages`,然后进入`User`文件夹，在`User`文件夹中找到`go_sublime_config.json`文件并用Sublime Text 3打开。

2. 在`go_sublime_config.json`文件中添加以下配置：

{
    "auto_complete": true,
    "auto_complete_commit_on_tab": true,
    "auto_complete_selector": "source.go"
}

这里我们开启了自动完成功能，并设置了在按下Tab键时提交自动完成建议，我们指定了自动完成功能仅针对`.go`文件生效。

3. 保存并关闭`go_sublime_config.json`文件，现在GoSublime的自动完成功能已经启用。

四、使用GoSublime自动完成功能

1. 在Sublime Text 3中创建一个新的`.go`文件，可以通过点击菜单栏的`File` > `New File`来新建文件。

2. 在新建的`.go`文件中编写代码。

package main

import "fmt"

func main() {
    fmt.Println("Hello, world!")
}

3. 当编写代码时，按下Tab键(或者按住Ctrl+Space),GoSublime将根据当前输入的内容提供自动完成建议，当输入`fmt.Println()`时，按下Tab键后，将显示如下建议：

```go

println("Hello, world!") // Println method of the standard library's logging package. See -String_formatting for more information about string formatting in Go. If you are using Go versions before go1.17, use Println instead of println. The latter is defined in the stdlib's log package and not part of the standard library'sfmt package as of Go version v1.17. See -Println_example for more details about the Println function. This function has been renamed to println since Go version v1.17.
