github代碼搜索技巧

 github是一個很是豐富的資源，可是面對這豐富的資源不少人不知到怎麼使用，更談不上怎麼貢獻給他，咱們須要使用github就要學習使用他的方法， 學會了使用的方法，接受了他的這種觀點咱們纔會慢慢的給他貢獻本身的力量，這是我本身在學習的時候的一個筆記。如今分享給你們但願可以對一些人有幫助。

github搜索之代碼搜索

Searching code

代碼搜索

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.

以上是代碼搜索中須要注意的一些問題

默認搜索是從master分支搜索代碼

只有小於384k的代碼纔是能夠搜索到的

搜索的時候必須包含至少一個搜索關鍵詞 如 amazing language:go

搜索語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的代碼

• octocat in:path

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

• 搜索路徑中有octocat的代碼

• octocat in:file,path

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

• 搜索路徑中有octocat的代碼或者文件中有octocat的代碼

• display language:scss

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

• 搜索用scss寫的包含display的代碼

• Integer

• Matches code with the word "Integer".

• 搜索包含Integer的字段

• Search by language

  經過語言搜索代碼

  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.

• 搜索大小爲100字節的xml代碼

• user:mozilla language:markdown

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

• 搜索mozilla用戶下用markdown寫的代碼

• Search by the number of forks the parent repository has

  經過fork的數量或者是否有父節點的方式搜索

   

  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寫的 android相關的代碼而且被fork過

• 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.

• 搜索與function相關的python代碼，文件大小超過10kb

• Search by the location of a file within the repository

  按照目錄結構搜索

  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目錄下搜索console關鍵字

• form path:cgi-bin language:perl

• Finds Perl files under 

  cgi-bin 

  with the word "form" in them.

• 搜索cgi-bin目錄下包含form的perl代碼

• Search by filename

  經過文件名搜索

  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* 而且包含commands的代碼

• minitest filename:test_helper path:test language:ruby

• Finds Ruby files containing the word "minitest" named *test_helper* within the *test* directory.

• 在test目錄中搜索包含minitest且文件名匹配"*test_helper*"的代碼

• Search by the file extension

  根據擴展名來搜索代碼

  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目錄下以pm爲擴展名的代碼

• icon size:>200000 extension:css

• Finds files larger than 200 KB that end in 

  .css 

  and have the word "icon" in them.

• 搜索超過200kb包含icon的css代碼

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

  經過用戶或者組織來查找

  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
