Github代码搜索技巧：

很多人搜索github，但是芸芸众生，要找到自己想要的项目犹如海底捞针一般，今天教大家几项神技，可以快速找到自己想要的内容。

1、按star数目搜索，比如[JavaScript][]，要求星数，这样就能获取star数目最多的项目

2、follow一些github上面的大牛

请登录：https://github-ranking.com/

国内大牛：http://outofmemory.cn/github/

这里是搜索名人的网址：https://github.com/search

高级搜索：https://github.com/search/advanced

3、Awesome + 你的关键字：搜索一些优秀的框架、教程、项目等

![Center 1][]

4、看一些搜索技巧，设定条件进行搜索

地址：https://help.github.com/articles/searching-repositories/

5、通过readme看看人家是否发出pull request

看看这篇文章：http://blog.csdn.net/qianlong4526888/article/details/11529981

6、看explore推荐

https://github.com/explore

7、看看其他

http://blog.sina.com.cn/s/blog\_4e60b09d0102vcso.html

8、直接github上搜fackbook或者其他，可以看到他们的最新作品

github是一个非常丰富的资源，但是面对这丰富的资源很多人不知到怎么使用，更谈不上怎么贡献给他，我们需要使用github就要学习使用他的方法，学会了使用的方法，接受了他的这种观点我们才会慢慢的给他贡献自己的力量，这是我自己在学习的时候的一个笔记。现在分享给大家希望能够对一些人有帮助。

[Search][] / Searching code

github搜索之代码搜索

## Searching code ##

代码搜索

To search for code, use the following search qualifiers in any combination.

Tip: There's a list of [search syntaxes][] you can add to any search qualifier to further improve your results.

### Considerations for code search ###

Due to the complexity of searching code, there are a few restrictions on how searches are performed:

*  Only the default branch is considered. In most cases, this will be the `master` branch.
 *  Only files smaller than 384 KB are searchable.
 *  You must always include at least one search term when searching source code. For example, searching for [`language:go`][language_go] is not valid, while [`amazinglanguage:go`][amazinglanguage_go] is.
 *  At most, search results can show two fragments from the same file, but there may be more results within the file.
 *  You can't use the following wildcard characters as part of your search query:``., : ; / \ ` ' " = * ! ? # $ & + ^ | ~ < > ( ) { } []``. The search will simply ignore these symbols.

以上是代码搜索中需要注意的一些问题

默认搜索是从master分支搜索代码

只有小于384k的代码才是可以搜索到的

搜索的时候必须包含至少一个搜索关键词 [`如amazing language:go`][amazinglanguage_go]

搜索语句不能有特殊字符如``., : ; / \ ` ' " = * ! ? # $ & + ^ | ~ < > ( ) { } []``.

### Scope the search fields ###

指定搜索方式

[octocat in:file][octocat in_file]

Matches code where "octocat" appears in the file contents.

搜索文件中有octocat的代码

[octocat in:path][octocat in_path]

Matches code where "octocat" appears in the path name.

搜索路径中有octocat的代码

[octocat in:file,path][octocat in_file_path]

Matches code where "octocat" appears in the file contents or the path name.

搜索路径中有octocat的代码或者文件中有octocat的代码

[display language:scss][display language_scss]

Matches code with the word "display," that's marked as being SCSS.

搜索用scss写的包含display的代码

[Integer][]

Matches code with the word "Integer".

搜索包含Integer的字段

### Search by language ###

通过语言搜索代码

You can search for code based on what language it's written in. For example:

[element language:xml size:100][element language_xml size_100]

Matches code with the word "element" that's marked as being XML and has exactly 100 bytes.

搜索大小为100字节的xml代码

[user:mozilla language:markdown][user_mozilla language_markdown]

Matches code from all @mozilla's repositories that's marked as Markdown.

搜索mozilla用户下用markdown写的代码

### Search by the number of forks the parent repository has ###

通过fork的数量或者是否有父节点的方式搜索

If you would like forked results to appear, add the fork:true qualifier. For example:

[android language:java fork:true][android language_java fork_true]

Matches code in a forked repository with the word "android" that's written in Java.

搜索用java写的 android相关的代码并且被fork过

###  ###

The size qualifier filters results based on the size of the file in which the code is found. For example:

[function size:>10000 language:python][function size_10000 language_python]

Matches code with the word "function," written in Python, in files that are larger than 10 KB.

搜索与function相关的python代码，文件大小超过10kb

### Search by the location of a file within the repository ###

按照目录结构搜索

By including the path qualifier, you specify that resulting source code must appear at a specific location in a repository. Subfolders are considered during the search, so be as specific as possible. For example:

[console path:app/public language:javascript][console path_app_public language_javascript]

Finds JavaScript files with the word "console" in an app/public directory (even if they reside inapp/public/js/form-validators).

在app/public directory目录下搜索console关键字

[form path:cgi-bin language:perl][form path_cgi-bin language_perl]

Finds Perl files under cgi-bin with the word "form" in them.

搜索cgi-bin目录下包含form的perl代码

### Search by filename ###

通过文件名搜索

You can use the filename qualifier if there's a specific file you're looking for. For example:

[filename:.vimrc commands][filename_.vimrc commands]

Finds \*.vimrc\* files with the word "commands" in them.

搜索 文件名匹配\*.vimrc\* 并且包含commands的代码

[minitest filename:test\_helper path:test language:ruby][minitest filename_test_helper path_test language_ruby]

Finds Ruby files containing the word "minitest" named \*test\_helper\* within the \*test\* directory.

在test目录中搜索包含minitest且文件名匹配"\*test\_helper\*"的代码

### Search by the file extension ###

根据扩展名来搜索代码

The extension qualifier matches code files with a certain extension. For example:

[form path:cgi-bin extension:pm][form path_cgi-bin extension_pm]

Matches code with the word "form," under cgi-bin, with the .pm extension.

搜索cgi-bin目录下以pm为扩展名的代码

[icon size:>200000 extension:css][icon size_200000 extension_css]

Finds files larger than 200 KB that end in .css and have the word "icon" in them.

搜索超过200kb包含icon的css代码

### Search within a user's or organization's repositories ###

通过用户或者组织来查找

To grab a list of code from all repositories owned by a certain user or organization, you can use the usersyntax. For getting a list of code from a specific repository, you can use the repo syntax. For example:

[user:github extension:rb][user_github extension_rb]
