问题 This question already has an answer here: In Vim is there a way to delete without putting text in the register? 22 answers I love vim, but one common gotcha is: yank a line go to where you would like to paste it delete what's there paste your yank, only to discover that it pastes what you just deleted Obviously the workflow is delete first, yank second. But it would be reeeeeaaaaaalllly nice if I didn't have to. Anyone have a trick for this? Does vim have a paste buffer that works well, or is

Find and replace strings in vim on multiple lines

阅读更多关于 Find and replace strings in vim on multiple lines

问题 I can do :%s/<search_string>/<replace_string>/g for replacing a string across a file, or :s/<search_string>/<replace_string>/ to replace in current line. How can I select and replace words from selective lines in vim? Example: replace text from lines 6-10 , 14-18 but not from 11-13 . 回答1: The :&& command repeats the last substitution with the same flags. You can supply the additional range(s) to it (and concatenate as many as you like): :6,10s/<search_string>/<replace_string>/g | 14,18&& If

Replace tabs with spaces in vim

问题 I would like to convert tab to spaces in gVim. I added the following line to my _vimrc : set tabstop=2 It works to stop at two spaces but it still looks like one tab key is inserted (I tried to use the h key to count spaces afterwards). I'm not sure what should I do to make gVim convert tabs to spaces? 回答1: IIRC, something like: set tabstop=2 shiftwidth=2 expandtab should do the trick. If you already have tabs, then follow it up with a nice global RE to replace them with double spaces. 回答2:

How to paste over without overwriting register

阅读更多关于 How to paste over without overwriting register

Does anyone know of a way to paste over a visually selected area without having the selection placed in the default register? I know I can solve the problem by always pasting from an explicit register. But it's a pain in the neck to type " x p instead of just p Luc Hermitte "{register}p won't work as you describe. It will replace the selection with the content of the register. You will have instead to do something like: " I haven't found how to hide this function (yet) function!

阅读更多关于 Tab key == 4 spaces and auto-indent after curly braces in Vim

How do I make vi - Vim never use tabs (converting spaces to tabs, bad!), makes the tab key == 4 spaces, and automatically indent code after curly brace blocks like Emacs does? Also, how do I save these settings so I never have to input them again? I've seen other questions related to this, but it always seems to be a little off from what I want. Ken As has been pointed out in a couple of answers below, the preferred method now is NOT to use smartindent, but instead use the following (in your .vimrc ): filetype plugin indent on " show existing tab with 4 spaces width set tabstop=4 " when
