github代码搜索技巧

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。

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 is not valid, while amazing language: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

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
• Matches code where "octocat" appears in the file contents.
• 搜索文件中有octocat的代码
• 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
• 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
• 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
• 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
• 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
• 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
• 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
• 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
• 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
• 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
• 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
• 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
• 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
• Matches code from GitHub that ends in .rb.
• 查找github用户中以rb为扩展的代码
• repo:mozilla/shumway extension:as
• Matches code from @mozilla's shumway project that ends in .as.
• 搜索mozilla的shumway以as为扩展的代码
