first-composer

第一次嘗試寫(xiě)自己的composer

1.在GitHub上創(chuàng)建一個(gè)自己的項(xiàng)目建椰，然后拉取到本地

git clone https://github.com/XianglinLiu/first-composer.git

2.在對(duì)應(yīng)的項(xiàng)目目錄里面執(zhí)行composer init

cd first-composer
composer init #一路回車(chē)就可

然后可看到生成了文件composer.json

{
    "name": "xianglin/first-composer",
    "description": "this is a test composer",
    "authors": [
        {
            "name": "xianglin",
            "email": "793101759@qq.com"
        }
    ],
    "require": {}
}

3.在根目錄新建文件夾src

mkdir src

4.新建測(cè)試文件.TestComposer.php 并聲明命名空間

<?php
/**
 * Created by YupaoWang
 * User：liubo
 * Date：2020/5/26
 * Time：20:14
 */

namespace firstComposer;

class TestComposer
{
    public function showTime()
    {
        echo '當(dāng)時(shí)北京時(shí)間: ' . date('Y-m-d H:i:s');
    }
}

5.修改composer.json 新增autoload

{
  "name": "xianglin/first-composer",
  "description": "this is a test framework",
  "license": "MIT",
  "authors": [
    {
      "name": "xianglin",
      "email": "793101759@qq.com"
    }
  ],
  "autoload": {
    "psr-4": {
      "firstComposer\\": "src/"
    }
  },
  "require": {}
}

6.執(zhí)行tree 命令可以看到當(dāng)前目錄結(jié)構(gòu)

.
├── README.md
├── composer.json
└── src
    └── TestComposer.php

7.執(zhí)行composer install ，然后執(zhí)行tree查看當(dāng)前目錄文件

.
├── README.md
├── composer.json
├── src
│   └── TestComposer.php
└── vendor
    ├── autoload.php
    └── composer
        ├── ClassLoader.php
        ├── LICENSE
        ├── autoload_classmap.php
        ├── autoload_namespaces.php
        ├── autoload_psr4.php
        ├── autoload_real.php
        ├── autoload_static.php
        └── installed.json

8.進(jìn)行測(cè)試岛马，新建測(cè)試文件夾exp 新建測(cè)試文件index.php

<?php

require_once(__DIR__ . '../../vendor/autoload.php');

use firstComposer\TestComposer;

(new TestComposer())->showTime();

php exp/index.php

輸出:當(dāng)時(shí)北京時(shí)間: 2020-05-26 12:27:43%

9.編輯文件.gitignore

vim .gitignore
#寫(xiě)入以下數(shù)據(jù)
/vendor/

10.提交代碼到GitHub

git add .  
git commit -m ':rocket: 這個(gè)第一次自己寫(xiě)composer 組件'  
git pull && git push

11.檢測(cè)compser包 packagist.org

12.檢測(cè)正常棉姐，點(diǎn)擊提交即可,提交成功將會(huì)跳轉(zhuǎn)到已發(fā)布包的地址

13.打包命令,我是直接在GitHub上打包的。

    git tag 1.0 
    git push origin --tags

14.測(cè)試一下 ,隨便建一個(gè)文件夾執(zhí)行命令

composer require xianglin/first-composer

15.寫(xiě)一個(gè)測(cè)試文件index.php

<?php
require_once('autoload.php');

use firstComposer\TestComposer;

(new TestComposer())->showTime();

php vendor/index.php 
時(shí)北京時(shí)間: 2020-05-26 12:47:24%
