vimdiff vimmerge 配置及使用
1 Set up vimdiff
The vimdiff as a merge tool will display several buffers to show the yours/theirs/original changes.
The key point is to set up the vimdiff so that the buffer number in the vimdiff status line is visible.
First, add following code into your ~/.vimrc
set laststatus=2 "show the status lineset statusline=%-10.3n "buffer numberSecond, if you know the buffer number, you can use hot key like ",2" (press comma first, then press two as quickly as possible) to pull change from buffer number two.Add below code into your ~/.vimrc to set up hot keys:
map <silent> <leader>1 :diffget 1<CR> :diffupdate<CR>map <silent> <leader>2 :diffget 2<CR> :diffupdate<CR>map <silent> <leader>3 :diffget 3<CR> :diffupdate<CR>map <silent> <leader>4 :diffget 4<CR> :diffupdate<CR>注意： 设置hot key的时候，需要将<leader>替换为你需要设置的前导符号，例如如果设置 ",2" 为获取buffer 2 的内容，那么你需要将 <leader>设置为 ‘,‘
即：
map <silent> ,1 :diffget 1<CR> :diffupdate<CR>map <silent> ,2 :diffget 2<CR> :diffupdate<CR>map <silent> ,3 :diffget 3<CR> :diffupdate<CR>map <silent> ,4 :diffget 4<CR> :diffupdate<CR>
2 Set up git tool
To use vimdiff as default merge tool:
git config --global merge.tool vimdiffgit config --global mergetool.prompt false
3 Resolve merge conflict
Bob and Chen has edited same files. So please merge branch "bob" into "master" at first. Then merge from "chen". The merge conflicts will be created.
git branch # double check that we got three local branches: master, bob, chengit checkout master # set master branch as main branchgit merge bob #this is ok, because bob is the first one to merge changesgit merge chen # now some conflicts created because Bob has already edited and merged same files
Here is the explanation of each buffer:
| Buffer | Explanation | Buffer Number |
|---|---|---|
| THEIRS | contents of the file on the current branch | 2 |
| BASE | common base for the merge | 3 |
| YOURS | contents of the file to be merged. | 4 |
| MERGED | The file containing the conflict markers. You need edit and commit this file. | 1 |
You could use hot key ",2" (comma + two) ",3" (comma+three) ",4" (comma+four) to pick the content you want to use
(either THEIRS or BASE or YOURS) to replace the marked conflict in MERGED buffer whose buffer number is one.
Or you can edit the content directly in MERGED buffer. Anyway, git only care about the the file binding to MERGED buffer.
Any other buffer will be ignored by git.
You can use hot key "[c" and "]c" to navigate to previous/next conflict (including the conflict resolved by git automatically) in current file which is binding to MERGED buffer.
After finishing editing of the conflicting file in MERGED buffer, you can use hot key ":xa" to exit vimdiff. Git will open next conflicting file with vimdiff automatically.
When you have resolved all the conflicts, follow the hint of git to commit your changes.
