就我那点垃圾代码竟然也有人要抄?

小弟不才,去年学习 flutter 的过程中,搞过几个小玩具,其中就有一个将 json 数据转换成 dart class 的 idea 插件。

就我那点垃圾代码竟然也有人要抄?

半年多来,随着 flutter 的火热,github 上也有了那么几十个 star。后来我也发布到了全家桶插件官网。陆陆续续也有几千个的下载量了。对于我这个小透明来说,还是挺开心的,不管写得有多烂,总归是有人在用,总归是为 flutter 的生态贡献了自己的一点绵薄之力。

然而就在今天,当我想去看看那些下载量更高的同类项目的时候,很不凑巧的就让我发现了这么一个作品:

先上一张他的 gif 吧

敏感的我,一下子就感觉到了有点不对劲,于是我点开了他的源码开始查看,有如下收获:

我先看了下源码目录

1.ClassGenerator 类名一样的

2.NameValuePair/NamePair 极其相似,而且讲道理,NamePair 这个命名很不自然

3.Param 类名一样

4.Util/Utils 基本没差别

于是我开始对比代码细节

没耐心的朋友可以不用看代码,我以我的人格担保,最后的结论是没错的

ClassGenerator

是不是一个模子刻出来的?大量的函数名、属性名都是一致的,换行空行也都是一致的

NameValuePair/NamePair

我的

由于我已经将 NameValuePair 用 kotlin 改写了,下面的代码是从 git 提交记录里找到的

/**
 * Created by zhangll on 2018/8/3.
 */
public class NameValuePair {
    String name;
    String value;

    public NameValuePair(String name, String value) {
        this.name = name;
        this.value = value;
    }
}
复制代码

他的

public class NamePair {
    private String camelKey;
    private String key;
    private String value;

    public NamePair(String camelKey, String key, String value) {
        this.camelKey = camelKey;
        this.key = key;
        this.value = value;
    }

    public String getCamelKey() {
        return camelKey;
    }

    public void setCamelKey(String camelKey) {
        this.camelKey = camelKey;
    }

    public String getKey() {
        return key;
    }

    public void setKey(String key) {
        this.key = key;
    }

    public String getValue() {
        return value;
    }

    public void setValue(String value) {
        this.value = value;
    }
}
复制代码

乍一看似乎不一样,其实他只是多写了 getter setter,又加了一个驼峰命名功能的字段。我怎么看出来一致的呢?因为 NameValuePair 严格来说,就应该给属性命名 name 和 value。而另一个人的类名叫 NamePair,中间偏偏少了个 Value ,属性命名却又是 key(不是理论上的 name)、value,这是为什么呢?明眼人应该一看就知道了。

写文件的代码好像有不同?没关系,我 git 里拉老代码出来

// 将 string 写入文件
public static void writeToFile(VirtualFile file, String content) {
    try {
        file.setBinaryContent(content.getBytes());
    } catch (IOException e) {
        e.printStackTrace();
    }
}

所以,唯一的不同就是我类头有注释,而他多了一个驼峰命名的方法。

放上另一个人的项目地址,有闲心的朋友可以自己去看

github.com/xlyasdasd/F…

总结一下

如果就 copy 一下我的代码过去用,其实我肯定也没什么,按道理来说作为一个程序猿我还应该觉得开心才是。

但是 copy 了我整个项目,又极其不专业的只改了几个不痛不痒的地方,改得此地无银三百两,留着项目结构、类命名、方法命名、空行、换行这些个人风格浓重的东西不动,我是 Kotlin 写的地方他就是 Kotlin,我用 Java 写的地方他就是 Java, 难道是因为核心逻辑看不懂不敢改动吗?既然能自己加上驼峰命名的功能,想来也不至于。

如果只是 copy 项目也就罢了,他甚至还发布到了全家桶插件的官网,如果不是因为下载量比我自己的插件还高,恐怕这事我到死都不会知道。

当然,他没什么错,是我自己没给开源项目加上 LICENSE。但想来就算我有 LICENSE,按他能去发布插件这个勇气来看,只怕也是不在乎的。

有朋友跟我说,我应该开心,应该有成就感,因为至少这证明我做的东西是有价值的,但我觉得事情不应该这么去看待。我花了心思去写出来的东西,我心肝情愿的开源,我心肝情愿的给别人用,但是拿了我的心血去换个包装贴上他自己的牌子,这谁能接受?

作为一个喜欢 flutter 的开发者,我也不至于因为这事就丧了气,尽管也付出了不少时间,做了不少迭代,但毕竟只是一个小玩具项目而已。只是这次被好好的上了一课,以后不论多小的项目,LICENSE 是一定不能少的。
