[英]Emacs Search exact word
I'm working in verilog most of the time, and my favorite editor is emacs. 我大部分时间都在verilog工作,而我最喜欢的编辑器就是emacs。
There a feature in vi (vim) I like but I don't know how to do it in emacs 我喜欢vi(vim)中的一个功能,但我不知道如何在emacs中执行此操作
I would like to do an exact word search, for example - let's say I have this text: 我想做一个确切的单词搜索,例如 - 假设我有这样的文字:
1. wire axi_bvalid = bvalid;
2. wire axi_bready; // assigned later
3. assign axi_cross_fifo_pop = axi_bvalid & axi_bready
4. wire axi = 1'b1;
when searching for axi
i would like to get match only on line 4. Today Ctrl-S search will match every instance of axi
. 当搜索
axi
我想仅在第4行获得匹配。今天Ctrl-S搜索将匹配axi
每个实例。
In vim the way to do it is press * on the word or /\\. 在vim中,这样做的方法是在单词或/ \\上按*。
Is there something similar in emacs? emacs中有类似的东西吗?
Thanks allot, Jony 谢谢分配,Jony
I think you are searching for the Word Search feature, activated with Ms w
. 我想您正在搜索使用
Ms w
激活的单词搜索功能。
You can use it in two ways: simply issue Ms w
, then type the word to search. 您可以通过两种方式使用它:只需发出
Ms w
,然后键入要搜索的单词。 Or to get something similar to *
in vim, you can start a search with isearch, with Cs Cw
(this searches for the word under cursor), then Ms w
to toggle the search to whole word mode. 或者为了在vim中获得与
*
相似的东西,你可以用issarch开始搜索,用Cs Cw
(这会搜索光标下的单词),然后Ms w
将搜索切换到整个单词模式。
Needs a regular-expression based search, for example 例如,需要基于正则表达式的搜索
Mx isearch-forward-regexp
RET \\_<axi\\_>
RET Mx
isearch-forward-regexp
RET \\_<axi\\_>
RET
See Emacs Lisp Info-file, node 34.3.1.3: Backslash Constructs in Regular Expressions 请参阅Emacs Lisp信息文件,节点34.3.1.3:正则表达式中的反斜杠构造
Running as command: 作为命令运行:
(defun my-re-search-forward (&optional word)
"Searches for the last copied solitary WORD, unless WORD is given. "
(interactive)
(let ((word (or word (car kill-ring))))
(re-search-forward (concat "\\_<" word "\\_>") nil t 1)
(set-mark (point))
(goto-char (match-beginning 0))
(exchange-point-and-mark)))
Bind it to Cc : for example: 将它绑定到抄送:例如:
(global-set-key [(control c) (\:)] 'my-re-search-forward)
I didn't find a built-in function in Emacs that is equivalent to vim's * , but I did manage to write these two commands which may suite you: 我没有在Emacs中找到相当于vim *的内置函数,但我确实设法编写了这两个可能适合你的命令:
(defun my-isearch-forward-word-at-point ()
"Search for word at point."
(interactive)
(let ((word (thing-at-point 'word t))
(bounds (bounds-of-thing-at-point 'word)))
(if word
(progn
(isearch-mode t nil nil nil t)
(when (< (car bounds) (point))
(goto-char (car bounds)))
(isearch-yank-string word))
(user-error "No word at point"))))
(defun my-isearch-forward-symbol-at-point ()
"Search for symbol at point."
(interactive)
(let ((symbol (thing-at-point 'symbol t))
(bounds (bounds-of-thing-at-point 'symbol)))
(if symbol
(progn
(isearch-mode t nil nil nil 'isearch-symbol-regexp)
(when (< (car bounds) (point))
(goto-char (car bounds)))
(isearch-yank-string symbol))
(user-error "No symbol at point"))))
(global-set-key (kbd "M-s ,") 'my-isearch-forward-word-at-point)
(global-set-key (kbd "M-s .") 'my-isearch-forward-symbol-at-point)
As you see, I bound these command to Ms , and Ms . 如你所见,我将这些命令绑定给Ms和Ms。 .
。 Depending on your version of Emacs, you may be able to use the built-in command
isearch-forward-symbol-at-point
(bound to Ms . by default). 根据您的Emacs版本,您可以使用内置命令
isearch-forward-symbol-at-point
(默认情况下绑定到Ms。 )。
