快速上手

npm安装vue-web-terminal

//  vue2安装
npm install vue-web-terminal@2.xx --save

//  vue3安装
npm install vue-web-terminal@3.xx --save 

main.js中载入 Terminal 插件

import Terminal from 'vue-web-terminal'

// for vue2
Vue.use(Terminal)

// for vue3
const app = createApp(App)
app.use(Terminal)

使用示例

<template>
  <div id="app">
    <terminal name="my-terminal" @execCmd="onExecCmd"></terminal>
  </div>
</template>

<script>
import Terminal from "vue-web-terminal"

export default {
  name: 'App',
  components:{Terminal},
  methods: {
    onExecCmd(key, command, success, failed) {
      if (key === 'fail') {
        failed('Something wrong!!!')
      } else if (key === 'json') {
        //  do something here
        success({
          type: 'json',
          class: 'success',
          content: {
            k1: 'welcome to vue-web-terminal',
            k2: 120,
            k3: ['h', 'e', 'l', 'l', 'o'],
            k4: {k41: 2, k42: '200'}
          }
        })
      } else if (key === 'code') {
        success({
          type: 'code',
          class: 'system',
          content: 'import Terminal from \'vue-web-terminal\'\n' +
              '\n' +
              'Vue.use(Terminal)'
        })
      } else if (key === 'table') {
        success({
          type: 'table',
          content: {
            head: ['title1', 'title2', 'title3', 'title4'],
            rows: [
              ['name1', 'hello world', 'this is a test1', 'xxxxxxxx'],
              ['name2', 'hello world', 'this is a test2 test2', 'xxxxxxxx']
            ]
          }
        })
      } else {
        let allClass = ['success', 'error', 'system', 'info', 'warning'];

        let clazz = allClass[Math.floor(Math.random() * allClass.length)];
        success({
          type: 'normal',
          class: clazz,
          tag: '成功',
          content: command
        })
      }
    }
  }
}
</script>

<style>
body, html, #app {
  margin: 0;
  padding: 0;
  width: 100%;
  height: 100%;
}
</style>

插件文档

Select Attributes

terminal标签支持属性参数表

Select Events

terminal标签支持事件表

Api

本插件提供了一些 Api 可以使用 Vue 主动向插件发起事件请求。

import Terminal from "vue-web-terminal"

//  获取api
Terminal.$api

向Terminal推送一条消息

let name = 'my-terminal'   //  每一个terminal都会定义一个name，详情见前面文档
let message = {
    type: 'normal',
    class: 'warning',
    content: 'This is a wanning message.'
}

Terminal.$api.pushMessage(name, message)

修改上下文

比如当前输入行$ /vue-web-terminal/tzfun > 的 /vue-web-terminal/tzfun 就是上下文，上下文文本可以由开发者自由设置 ，但是需使用.sync绑定一个变量

<template>
  <div id="app">
    <terminal name="my-terminal" :context.sync="context"></terminal>
  </div>
</template>

<script>
import Terminal from "vue-web-terminal"

export default {
  name: 'App',
  data() {
    return {
      context: '/hello'
    }
  },
  methods: {
    _updateContext(newCtx) {
      Terminal.$api.updateContext("my-terminal", newCtx)
    }
  }
}
</script>

消息对象

本插件定义了消息对象，任何消息需按照此格式定义才能正确显示。

normal 普通文本

content为字符串格式，支持html标签，time字段会在push时自动填充，content、type必填，其他选填

{
  "time": "2022-02-17 18:12:20",
  "class": "success",
  "type": "normal",
  "content": "这是一条普通文本消息",
  "tag": "Tag success"
}

json

type为json时content需传一个json对象

{
  "type": "json",
  "content": {
    "key": "value",
    "num": 1
  }
}

code

type为code时content类型为字符串，直接传入文本或代码即可

{
  "type": "json",
  "content": "import Terminal from 'vue-web-terminal'\n\nVue.use(Terminal)"
}

highlight.js 代码高亮

code类型消息支持 highlight.js 高亮显示

首先你需要配置 Highlight.js，在main.js入口安装，详细配置见https://www.npmjs.com/package/highlight.js

import Terminal from 'vue-web-terminal'
import hljs from 'highlight.js'
import java from 'highlight.js/lib/languages/java'
import vuePlugin from "@highlightjs/vue-plugin"
import 'highlight.js/styles/tomorrow-night-bright.css'

hljs.registerLanguage('java', java)
Vue.use(vuePlugin)
Vue.use(Terminal, {highlight: true})

vue2版本推荐

{
  "@highlightjs/vue-plugin": "^1.0.2",
  "highlight.js": "^10.7.3"
}

codemirror 代码高亮

code类型消息也支持 codemirror 高亮显示，详细配置见https://www.npmjs.com/package/vue-codemirror

同样只需要在main.js入口安装即可，版本推荐："vue-codemirror": "^4.0.6"

import VueCodemirror from 'vue-codemirror'
import 'codemirror/lib/codemirror.css'
import 'codemirror/theme/darcula.css'
import 'codemirror/mode/clike/clike.js'
import 'codemirror/addon/edit/closebrackets.js'

Vue.use(VueCodemirror)
Vue.use(Terminal, {
    codemirror: {
        tabSize: 4,
        mode: 'text/x-java',
        theme: "darcula",
        lineNumbers: true,
        line: true,
        smartIndent: true
    }
})

table

type为table时content为表格配置，head为表头，rows为每行的数据，支持html标签

{
  "type": "table",
  "content": {
    "head": [
      "title1",
      "title2",
      "title3",
      "title4"
    ],
    "rows": [
      [
        "name1",
        "hello world",
        "this is a test1",
        "xxxxxxxx"
      ],
      [
        "name2",
        "hello world",
        "this is a test2 test2",
        "xxxxxxxx"
      ]
    ]
  }
}

html

type为html时可自定义内容格式，content为html标签构成

execCmd(key, command, success)
{
    // ...
    success({
        type: 'html',
        content: `
          <ul class="custom-content">
            <li class="t-dir">目录1</li>
            <li class="t-dir">目录2</li>
            <li class="t-dir">目录3</li>
            <li class="t-file">文件1</li>
            <li class="t-file">文件2</li>
            <li class="t-file">文件3</li>
          </ul>
          `
    })
    // ...
}

命令定义

如果开启了命令帮助搜索功能，在实例化Terminal之前需要传入自定义命令库，传入的命令库为 N 个命令的数组，以下是命令格式定义规则：

命令示例格式

示例格式比较简单，des为描述，cmd为具体的命令，json格式如下：

[
  {
    "des": "获取所有任务信息",
    "cmd": "task -u 11001 -o pack"
  },
  {
    "des": "获取任务进度",
    "cmd": "task -u 11001 -o query -id 1001"
  }
]

内置命令

Terminal默认内置有以下命令，且不可替代

[
  {
    "key": "help",
    "title": "Help",
    "group": "local",
    "usage": "help [pattern]",
    "description": "Show command document.",
    "example": [
      {
        "des": "Get help documentation for exact match commands.",
        "cmd": "help refresh"
      },
      {
        "des":"Get help documentation for fuzzy matching commands.",
        "cmd": "help *e*"
      }
    ]
  },
  {
    "key": "clear",
    "title": "Clear logs",
    "group": "local",
    "usage": "clear [history]",
    "description": "Clear screen or history.",
    "example": [
      {
        "cmd": "clear",
        "des": "Clear all records on the current screen."
      },
      {
        "cmd": "clear history",
        "des": "Clear command history."
      }
    ]
  },
  {
    "key": "refresh",
    "title": "Refresh page",
    "group": "local",
    "usage": "refresh",
    "description": "Refresh current page."
  },
  {
    "key": "open",
    "title": "Open page",
    "group": "local",
    "usage": "open <url>",
    "description": "Open a specified page.",
    "example": [
      {
        "cmd": "open blog.beifengtz.com"
      }
    ]
  }
]
