Tips and suggestions

Jump :_行号_ by _行号_gg : _gg or line number. Jumps are recorded in a jump list, for more :h jump-motions

Spell check

Vim has spell checking, which is turned on with the following command:

set spell

Vim only has an English dictionary installed by default. O ther dictionaries can be found by searching for vim-spell in the Official Software Warehouse. Check the available language packs:

# pacman -Ss vim-spell

Additional dictionaries can be obtained from vim's FTP archive. Put the downloaded dictionary file ~/.vim/spell/ open :setlocal spell spelllang=_en_us_ _en_us_ with the name of the dictionary you want).

Tips:

• If you need spelling checking for two languages ~/.vimrc English and German), add set spelllang=_en,de_ in .vimrc or /etc/vimrc and restart Vim.

• With the FileType plug-in and self-built rules for file type detection, you can turn on spell checking for any file type. For example, to turn on .txt a file with the extension .txt, create a file /usr/share/vim/vimfiles/ftdetect/plaintext.vim add autocmd BufRead,BufNewFile *.txt setfiletype plaintext and then add autocmd FileType plaintext setlocal spell spelllang=en_us /etc/vimrc en_us and restart vim. ~/.vimrc

• If you want to use spell checking only for LaTeX (or TeX) documents, just restart Vim by adding autocmd FileType **tex** setlocal spell spelllang=_en_us_ /etc/vimrc _en_us_. ~/.vimrc For non-English languages, replace the en_us en_us above as the appropriate language code.

Record the cursor position

Vim can record the cursor position the last time a file was opened and move the cursor to that location the next time the same file is opened. To turn this on, add the following to your profile , ~/.vimrc

augroup resCur
  autocmd!
  autocmd BufReadPost * call setpos(".", getpos("'\""))
augroup END

Replace vi with vim

Create an alias, as follows:

alias vi=vim

Or, if you sudo vi and get vim install vi-vim-symlink AUR, vi and replace it with a symbolic link vim

DOS/Windows carriage return issue

When you open a text file created under MS-DOS or Windows, you often end each line with a ^M This is because Linux uses Unix-style line breaks to represent the end of a line with a line break (LF), but in Windows, MS-DOS, one carriage return (CR) after another line break (LF), so the carriage return character is displayed ^M

You can use the following command to remove carriage returns from the file:

:%s/^M//g

Note that ^ represented by the . The way to enter the ^M is Ctrl+v,Ctrl+m

Another workaround is to install dos2unix and then perform dos2unix <文件名> .

The space at the bottom of the gVim window

If Window Manager is set to ignore window-sized rendering windows, gVim fills the blank space with a GTK theme background color, which can look ugly.

The solution is to resize the space that gVim reserves at the bottom of the window. Add the following code ~/.vimrc

set guiheadroom=0

Note: If you set it to 0, you won't see the horizontal scroll bar at the bottom.
