Customising word separators in vi

由 柔情痞子 提交于 2019-11-26 19:33:17
问题 vi treats dash - and space as word separators for commands such as dw and cw . Is there a way to add underscore _ as well? I quite often want to change part of a variable name containing underscores, such as changing src_branch to dest_branch . I end up counting characters and using s (like 3sdest ), but it would be much easier to use cw (like cwdest ). 回答1: In case you're using vim, you can change that by setting the iskeyword option ( :he iskeyword ). If that is not an option, you can

Easiest way to swap occurrences of two strings in Vim?

问题 What is the easiest way to replace all occurrences of string_a with string_b while at the same time changing anything that was already string_b into string_a ? My current method is as follows: :s/string_a/string_c/g :s/string_b/string_a/g :s/string_c/string_b/g Although this works, it requires extra typing and seems inefficient. Does anybody know of a better way to do this? 回答1: I'd do it like this: :%s/\v(foo|bar)/\={'foo':'bar','bar':'foo'}[submatch(0)]/g But that's too much typing, so I'd

How do I use vi keys in ipython under *nix?

问题 Currently in Bash I use set -o vi to enable vi mode in my bash prompt. How do I get this going in ipython? Note: If an answer applies to all *nix, I'll remove the OS X from the title :) 回答1: In case someone's wandering in here recently, IPython 5.0 switched from readline to prompt_toolkit, so an updated answer to this question is to pass an option: $ ipython --TerminalInteractiveShell.editing_mode=vi ... or to set it globally in the profile configuration ( ~/.ipython/profile_default/ipython

Doesn't exactly roll off the fingers, but: gg"+yG 回答3: A working solution in old vi is :r

Copy and paste content from one file to another file in vi

由 假装没事ソ 提交于 2019-11-26 18:45:22
问题 I am working with two files, I need to copy a few lines from one file and paste into another file. I know how to copy (yy) and paste(p) in the same file. But that doesn't work for different files, how is this done?? Also, is there a way to cut-paste? I have tried googling, but most of the resources only talk about copy-paste. 回答1: Since you already know how to cut/yank text, here are a few ideas for pasting it back into another file: Edit the first file, yanking the text you want. Then open

How do I fix the indentation of an entire file in Vi?

由 六眼飞鱼酱① 提交于 2019-11-26 17:52:51
问题 In Vim, what is the command to correct the indentation of all the lines? Often times I'll copy and paste code into a remote terminal and have the whole thing messed up. I want to fix this in one fell swoop. 回答1: = , the indent command can take motions. So, gg to get the start of the file, = to indent, G to the end of the file, gg=G . 回答2: Before pasting into the terminal, try :set paste and then :set nopaste after you're done. This will turn off the auto-indent, line-wrap and other features

Linux cat中文正常vi中文乱码 问题示例 /*--> */ /*--> */ 出现此问题，有可能是vim 编辑器的配置编码方面的问题。 出现此情况,在vim 编辑器中输入 :e ++enc=utf8 :e ++enc=zh_CN 如果上面两次处理的结果中，有一个可以让乱码变为中文，那么说明打开文件时所使用的编码是不兼容中文的。 需要修改vim的配置。 vim的用户配置文件是$HOME/.vimrc , 我们在这个配置文件中加入以下内容: set fileencodings=utf-8,gbk,gb2312,gb18030 set fileencoding=utf8 set encoding=utf8 执行source ~/.vimrc 使配置生效 再次打开文件： 可以看到vi 编辑文件时已经可以正常显示中文。 Author: halberd.lee Created: 2019-08-09 Fri 16:53 Validate 来源： https://www.cnblogs.com/halberd-lee/p/11328284.html

Make Vim show ALL white spaces as a character

由 僤鯓⒐⒋嵵緔 提交于 2019-11-26 16:50:27
I can't find a way to make Vim show all white spaces as a character. All I found was about tabs, trailing spaces etc. Rook As others have said, you could use :set list which will, in combination with :set listchars=... display invisible characters. Now, there isn't an explicit option which you can use to show whitespace, but in listchars, you could set a character to show for everything BUT whitespace. For example, mine looks like this :set listchars=eol:$,tab:>-,trail:~,extends:>,precedes:< so, now, after you use :set list everything that isn't explicitly shown as something else, is then,
