GitHub 在开源世界的受欢˜qŽç¨‹åº¦è‡ªä¸å¿…多言。再加上前阵子，GitHub 官方又搞了个大新闻：¿Uæœ‰ä»“库改äؓ免费使用åQŒè¿™åœ¨åŽŸæ¥å¯æ˜¯éœ€è¦çœŸé‡‘白银的买的。可见微软收购后åQŒä¾ç„¶æ²¡æœ‰æ”¹å?GitHub 的定位，甚至˜q˜æ›´˜q›ä¸€æ­¥ã€?/p>

花开两朵åQŒå„表一枝。我们今天想要聊的åƈ不是 GitHub 多么厉害åQŒè€Œæ˜¯ä½?strong>怎么能把 GitHub 用得很厉å®?/strong>ã€?/p>

你在 GitHub 上搜索代码时åQŒæ˜¯æ€Žä¹ˆæ äh“ä½œçš„呢？是不是就像这æ øP¼Œç›´æŽ¥åœ¨æœç´¢æ¡†é‡Œè¾“入要‹‚€ç´¢çš„内容åQŒç„¶åŽä¸æ–­åœ¨åˆ—表里翻™å‰|‰¾è‡ªå·±éœ€è¦çš„内容åQ?/p>

或者是½Ž€å•ç­›é€‰ä¸‹åQŒåœ¨å·¦ä¾§åŠ ä¸ªè¯­è¨€çš„过滤项ã€?/p>

再或者改变一下列表的排序方式

˜q™å°±æ˜¯ã€Œå…¨éƒ¨ã€äº†å—？

一般的¾pȝ»Ÿ‹‚€ç´¢åŠŸèƒ½ï¼Œéƒ½ä¼šæœ‰ä¸€ä¸ªã€Œé«˜¾U§æœç´¢ã€çš„功能。需要在另外的界面里展开åQŒè¿›è¡ŒäºŒ‹Æ¡æœç´¢ä¹‹¾cȝš„ã€?GitHub 有没有类似的呢？

½{”案是肯定的。做ä¸ÞZ¸€ä¸ªäؓ万千工程师提供服务的¾|‘ç«™åQŒä¸ä»…要有，而且˜q˜è¦æŠ€æœ¯èŒƒå„ѝ€?/p>

如果我们自己开发一个类似的应用åQŒä¼šæ€Žæ ·å®žçŽ°å‘¢ï¼Ÿ

带着思èµ\åQŒå’±ä»¬ä¸€èµäh¥çœ‹çœ‹åQŒGitHub 是怎样做的ã€?/p>

˜q™é‡Œæˆ‘们假设正要学习 Spring CloudåQŒè¦æ‰¾ä¸€ä¸?Spring Cloud çš?Demo 参考练手ã€?/p>

1. 明确搜烦仓库标题、仓库描˜q°ã€README

GitHub 提供了便æïLš„搜烦方式åQŒå¯ä»¥é™å®šåªæœçƒ¦ä»“库的标题、或者描˜q°ã€README½{‰ã€?/p>

以Spring Cloud ä¸ÞZ¾‹åQŒä¸€èˆ¬ä¸€ä¸ªä»“库，大概是这æ ïLš„

其中åQŒçº¢è‰²ç®­å¤´æŒ‡çš„两个地方，分别是仓库的名称和描˜q°ã€‚咱们可以直接限定关键字只查特定的地斏V€‚比如咱们只æƒÏxŸ¥æ‰¾ä»“库名¿U°åŒ…å?spring cloud 的仓库，可以使用语法

in:name 关键�/strong>

如果æƒÏxŸ¥æ‰¾æ˜q°çš„内容åQŒå¯ä»¥ä‹É用这æ ïLš„方式åQ?/p>

in:descripton 关键�/strong>

˜q™é‡Œž®±æ˜¯æœçƒ¦ä¸Šé¢™å¹ç›®æè¿°çš„内宏V€?/p>

一般项目，都会有个READMEæ–‡äšgåQŒå¦‚果要查该文äšg包含特定关键词的话，我想你猜åˆîCº†

in:readme 关键�/strong>

2. 明确搜烦 star、fork 数大于多ž®‘çš„

一个项ç›?star 数的多少åQŒä¸€èˆ¬ä»£è¡¨è¯¥™å¹ç›®æœ‰å—‹Æ¢è¿Ž½E‹åº¦ã€‚虽然现在也有垃åœùN¡¹ç›®åˆ· star åQŒä½†æ¯•ç«Ÿæ˜¯å°‘敎ͼŒ star 依然是个不错的衡量标准ã€?/p>

stars:> 数字 关键字�/strong>

比如å’׃»¬è¦æ‰¾ star 数大äº?3000 çš„Spring Cloud 仓库åQŒå°±å¯ä»¥˜q™æ ·

stars:>3000 spring cloud

如果不加 >= 的话åQŒæ˜¯è¦ç²¾¼‹®æ‰¾ star 数等于具体数字的åQŒè¿™ä¸ªä¸€èˆ¬æœ‰ç‚¹å›°éš¾ã€?/p>

如果要找在指定数字区间的话，使用

stars: 10..20 关键�/strong>

fork 数同理，ž®†ä¸Šé¢çš„ stars 换成forkåQŒå…¶å®ƒè¯­æ³•ç›¸å?/p>

3. 明确搜烦仓库大小�/strong>

比如你只想看个简单的 DemoåQŒä¸æƒÏx‰¾ç‰¹åˆ«å¤æ‚的且占用¼‚ç›˜½Iºé—´è¾ƒå¤šçš„，可以在搜索的时候直接限定仓库的sizeã€?/p>

使用方式åQ?/p>

size:>=5000 关键�/strong>

˜q™é‡Œæ³¨æ„ä¸‹ï¼Œ˜q™ä¸ªæ•°å­—代表K, 5000代表着5Mã€?/p>

4. 明确仓库是否˜q˜åœ¨æ›´æ–°¾l´æŠ¤

我们在确认是否要使用一些开源äñ”品，框架的时候，是否¾l§ç®‹¾l´æŠ¤æ˜¯å¾ˆé‡è¦çš„一炏V€‚如果已¾lè¿‡æ—¶æ²¡äººç»´æŠ¤çš„东西åQŒè¸©äº†å‘ž®×ƒ¸å¥½åŠžäº†ã€‚而在 GitHub 上找™å¹ç›®çš„时候，不再需要每个都点到™å¹ç›®é‡Œçœ‹çœ‹æœ€˜q?push çš„æ—¶é—ß_¼Œç›´æŽ¥åœ¨æœç´¢æ¡†å›_¯å®Œæˆã€?/p>

元旦刚过åQŒæ¯”如咱们要找äÍ˜q‘年底依然在勤快更新的项目，ž®±å¯ä»¥ç›´æŽ¥æŒ‡å®šæ›´æ–°æ—¶é—´åœ¨å“ªä¸ªæ—‰™—´å‰æˆ–后的

通过˜q™æ ·ä¸€æ¡æœç´?strong>pushed:>2019-01-03 spring cloud

å’׃»¬ž®±æ‰¾åˆîCº†1æœ?号之后，˜q˜åœ¨æ›´æ–°çš„项目ã€?/p>

你是æƒÏx‰¾æŒ‡å®šæ—‰™—´ä¹‹å‰æˆ–之后创建的仓库也是可以的，æŠ?strong>pushedæ”ÒŽˆcreatedž®Þp¡Œã€?/p>

5. 明确搜烦仓库�LICENSE

å’׃»¬¾lå¸¸ä½¿ç”¨å¼€æºèÊYä»Óž¼Œä¸€å®šéƒ½çŸ¥é“åQŒå¼€æºèÊY件也是分不同的「门‹z¾ã€ä¸åŒçš„LICENSE。开源不½{‰äºŽä¸€åˆ‡å…è´¹ï¼Œä¸åŒçš„许可证要求也大不相同ã€?2018òq´å°±å‡ºçŽ°äº?Facebook 修改 React 的许可协议导致各个公司纷¾U·ä¿®æ”¹è‡ªå·Þqš„代码åQŒå¯»æ‰¾æ›¿æ¢çš„框架ã€?/p>

例如å’׃»¬è¦æ‰¾åè®®æ˜¯æœ€ä¸ºå®½æ„¡š„ Apache License 2 的代码，可以˜q™æ ·

license:apache-2.0 spring cloud

其它协议ž®±æŠŠ apache-2.0 替换一下即可，比如换成mit之类的ã€?/p>

6. 明确搜烦仓库的语­a€

比如å’׃»¬ž®±æ‰¾ Java 的库åQ?除了像上面在左侧点击选择之外åQŒè¿˜å¯ä»¥åœ¨æœç´¢ä¸­˜q‡æ×o。像˜q™æ ·åQ?/p>

language:java 关键�/strong>

7.明确搜烦某个人或¾l„织的仓åº?/strong>

比如å’׃»¬æƒ›_œ¨ GitHub 上找一下某个大¼œžæ˜¯ä¸æ˜¯æäº¤äº†æ–°çš„功能，ž®±å¯ä»¥æŒ‡å®šå…¶åç§°åŽæœç´¢ï¼Œä¾‹å¦‚å’׃»¬çœ‹ä¸‹ Josh Long 有没有提交新çš?Spring Cloud 的代码，可以˜q™æ ·ä½¿ç”¨

user:joshlong

¾l„合使用一下，æŠ?Java ™å¹ç›®˜q‡æ×o出来åQŒå¤šä¸ªæŸ¥è¯¢ä¹‹é—´ã€Œç©ºæ ¹{€åˆ†éš”即可ã€?/p>

user:joshlong language:java

找某个组¾l‡çš„代码话，可以˜q™æ ·åQ?/p>

org:spring-cloud

ž®±å¯ä»¥åˆ—出具体org 的仓库ã€?/p>
