在git仓库中找到一个函数 [英] Locating a function in a git repository

问题描述

我是Github和Jupyter笔记本的新手.
我想在git存储库中找到特定的函数，该怎么做?
我知道我可以使用Git grep，但是我不知道该命令.
另外，我可以使用Jupyter笔记本电脑执行此操作吗?还是必须使用终端机?

I am new to Github and Jupyter notebook.
I want to find a specific function in a git repository, how do I do it?
I have come to know that I could use Git grep, but I don't know the command.
Also, can I use Jupyter notebook to do this or do I have to use the terminal?

推荐答案

我不了解 Jupyter Notebook ，但请使用终端.确保您已经git clone d存储库并且在终端中其目录内.然后在终端上执行git grep.

I don't know about Jupyter Notebook, but use the terminal. Make sure you have already git cloned the repository and are inside its directory in the terminal. Then do git grep from the terminal.

1.使用git grep (您必须 必须位于git存储库中):

1. With git grep (you must be inside a git repo):

区分大小写的搜索. -n显示了在其中也找到结果的行号.

Case-sensitive search. The -n shows the line number where the result is found too.

git grep -n "my regular expression search string"

不区分大小写的搜索(在此处添加-i):

Case insensitive search (add -i here):

git grep -ni "my case insensitive regular expression search string"

查找功能用法(下面的左括号是可选的)

Find a function usage (left parenthesis below is optional)

git grep -n "myFunc("

Grep进行正则表达式搜索.谷歌它的详细信息.正则表达式是进行非常特定的字符串匹配的一种非常有效的方法.当您学习基础知识时，请在此处使用此工具练习测试和检查正则表达式(regex)搜索: https://regex101.com /.

Grep does regular expression search. Google it for details. Regular expressions are a very powerful way to do very specific string matching. As you learn the basics, practice testing and checking your regular expression (regex) searches with this tool here: https://regex101.com/.

2.使用常规grep (可在任何地方使用，但运行速度比git grep慢100倍):

与上面相同，除了为'r'ecursive添加-r(用于搜索目录).如果您也想遵循符号链接，请使用-R而不是-r.

Same as above, except add -r for 'r'ecursive (to search into directories). If you want to follow symbolic links too, use -R instead of -r.

示例:

区分大小写的搜索. -n显示了在其中也找到结果的行号.

Case-sensitive search. The -n shows the line number where the result is found too.

grep -rn "my regular expression search string"

不区分大小写的搜索(在此处添加-i):

Case insensitive search (add -i here):

grep -rni "my case insensitive regular expression search string"

查找功能用法(下面的左括号是可选的)

Find a function usage (left parenthesis below is optional)

grep -rn "myFunc("

查找功能(以下符号链接:添加-R):

Find a function (following symbolic links: add -R):

grep -Rn "myFunc("

---

奖金:按名称查找文件:

只需使用管道运算符(|)将find的输出管道传输为grep的输入:

---

Bonus: find a file by name:

Just pipe the output of find to be the input to grep with the pipe operator (|):

find | grep -ni "my_file_name"

或者，将-L与find一起使用以跟随符号链接:

Or, use -L with find to follow symbolic links:

find -L | grep -ni "my_file_name"

请注意，上面的-i用于不区分大小写的文件名搜索.删除它以匹配大小写.

Notice the -i above is for case-insensitive filename searches. Remove it to match the case too.

1. 多年来的随机体验，谷歌搜索和与人交谈
2. 阅读手册页(手册):

1. Random experience, Googling, and talking to people over the years
2. Read the man (manual) pages:

1. man git grep
2. man grep
3. man find

1. man git grep
2. man grep
3. man find
