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
masterbranch. - 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:gois not valid, whileamazing language:gois. - 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.
以上是代碼搜索中需要注意的一些問題
默認搜索是從master分支搜索代碼
只有小於384k的代碼纔是可以搜索到的
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:fileMatches code where "octocat" appears in the file contents.搜索文件中有octocat的代碼octocat in:pathMatches code where "octocat" appears in the path name.搜索路徑中有octocat的代碼octocat in:file,pathMatches 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:scssMatches code with the word "display," that's marked as being SCSS.搜索用scss寫的包含display的代碼IntegerMatches code with the word "Integer".搜索包含Integer的字段
Search by language
通過語言搜索代碼
You can search for code based on what language it's written in. For example:
element language:xml size:100Matches 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:markdownMatches 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
通過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:trueMatches code in a forked repository with the word "android" that's written in Java.搜索用java寫的 android相關的代碼並且被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:pythonMatches 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10kbSearch 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:javascriptFinds 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:perlFinds 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
通過文件名搜索
You can use the filename qualifier if there's a specific file you're looking for. For example:
filename:.vimrc commandsFinds *.vimrc* files with the word "commands" in them.搜索 文件名匹配*.vimrc* 並且包含commands的代碼minitest filename:test_helper path:test language:rubyFinds 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:pmMatches 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:cssFinds 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
通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:rbMatches code from GitHub that ends in .rb.查找github用戶中以rb爲擴展的代碼repo:mozilla/shumway extension:asMatches code from @mozilla's shumway project that ends in .as.搜索mozilla的shumway以as爲擴展的代碼
