[英]Emacs command for search in files
I want to search in all files from current folder for macro CODE_INIT_PARAMETERS. 我想在当前文件夹中搜索宏CODE_INIT_PARAMETERS的所有文件。 I can do Mx occur CODE_INIT_PARAMETERS but this shows only entries from open buffers.
我可以做Mx出现CODE_INIT_PARAMETERS但这只显示来自开放缓冲区的条目。
Is there any way to search all files from current folder, from Emacs, without switching to Mx shell and then grep ? 有没有办法从Emacs搜索当前文件夹中的所有文件,而无需切换到Mx shell然后grep? I want to avoid grep, because for some commands (Mx occur) Emacs do jumps to offending code, and I want that too.
我想避免使用grep,因为对于某些命令(Mx发生),Emacs会跳转到违规代码,我也想要这样做。 Thanks.
谢谢。
You can try Mx rgrep
. 你可以试试
Mx rgrep
。
It will ask for: 它会要求:
As an extra, it will exclude source control private directories from your search (like CVS, .svn or .git). 作为额外的,它将从搜索中排除源控制私有目录(如CVS,.svn或.git)。
Emacs provides a built-in command: Emacs提供了一个内置命令:
M-x grep RET CODE_INIT_PARAMETERS *.c
(and 'grep-find
to search sub directories) (和
'grep-find
搜索子目录)
Though I prefer the interface provided by an external package igrep
(which provides the commands igrep
and igrep-find
). 虽然我更喜欢外部包
igrep
(它提供命令igrep
和igrep-find
)提供的igrep
。
if you open a folder in dired, and mark all of the files (with 'm') you can run 'dired-do-search ('A' in my bindings). 如果您在dired中打开一个文件夹,并标记所有文件(使用'm'),您可以运行'dired-do-search(我的绑定中的'A')。 This will search all marked files.
这将搜索所有标记的文件。 To get to the next one, run tags-loop-continue (M-,)
要进入下一个,运行tags-loop-continue(M-,)
I have set up several elisp functions to mark various sub-sets of the files (.h files, .cpp files, etc) and to create a recursive dired to search a whole tree... 我已经设置了几个elisp函数来标记文件的各种子集(.h文件,.cpp文件等)并创建一个递归的dired来搜索整个树...
This is an improvement on Trey Jackson's suggestion. 这是Trey Jackson建议的改进。
Mx grep Mx grep
You will see the grep command, eg grep -nH -e
您将看到grep命令,例如
grep -nH -e
Add R to the first set of flags (for recursive), and put your search term after -e 将R添加到第一组标志(用于递归),并将搜索项放在-e之后
grep -nHR -e CODE_INIT_PARAMETERS
Hit RET. 点击RET。 The results will be understandable by Emacs -- you will be able to click or otherwise navigate to them, like Mx occur.
Emacs可以理解结果 - 您可以点击或以其他方式导航到它们,就像Mx一样。 You may need to put the search directory at the end of the command:
您可能需要将搜索目录放在命令的末尾:
grep -nHR -e CODE_INIT_PARAMETERS /path/to/root/of/search
Mx find-grep-dired的工作方式与rgrep类似
In cases where 在哪些情况下
you might consider using etags
and invoking either find-tag
(bound to M-.
by default) or tags-search
(no default binding but can be continued with M-,
). 您可以考虑使用
etags
并调用find-tag
(默认绑定到M-.
)或tags-search
(没有默认绑定但可以继续使用M-,
)。
There is as well ack-grep mode for emacs which use the ack-grep tool which is specifically designed for ''grepping'' programming languages and IMHO looks nicer than the output of Mx grep. 对于使用ack-grep工具的emacs也有ack-grep模式 ,该工具专为''grepping''编程语言而设计,而IMHO看起来比Mx grep的输出更好。
But as mentioned earlier etags should be the proper way! 但如前所述,etags应该是正确的方法!
