When we are using Neovim, we often open several files in a window. Each file correponds to a buffer. How to switch to a buffer quickly?
The native way
In command mode, some of the commands to change buffers are list below:
:bfirst: change to first buffer
:blast: change to last buffer
:bnext: change to next buffer
:bprevious: change to previous buffer
Or you can use
:b <TAB> to choose from currently opened buffers.
If there are a few buffers, it is easy to switch using the above command. But if we have a dozen of opened buffers, it is cumbersome to use these commands.
Switching buffers using buffer number
Fortunately, we can switch to a buffer quickly if we know its number. To get a
buffer’s number, use
:buffers command in normal mode. It will print something
3 "train.py" line 1 4 %a "main.py" line 17 6 "keys.py" line 1 7 "utils.py" line 1 8 # "val_CTC.py" line 2
The first number is the number corresponding to each buffer. Then we can use
NUM Ctrl-6 to go to a particular buffer (replace
NUM with actual buffer
number). But this is still inconvenient — since we have to find the buffer
A better solution for buffer switching
If you have installed vim-airline
，you can configure it to show the buffer number on the top of the window
tabline. Just add the following settings to Nvim config file
let g:airline#extensions#tabline#enabled = 1 let g:airline#extensions#tabline#buffer_nr_show = 1
Restart Nvim and you will find that each buffer has a number on the left of the file name. Then you can easily go to a buffer.
