bufjump.mov
Have you ever had to temporarily go to another file, perhaps previewing some changes with lsp go to refrenece, fiddle a bit, and have to jump back to the main file that you were working with? Instead of aimlessly smashing CTRL-o
and CTRL-i
, bufjump.nvim allows you to jump to previous or next buffer in the vim native jumplist with one single command.
- Neovim 0.5 or higher
with vim-plug
Plug 'kwkarlwang/bufjump.nvim'
with packer.nvim
use {
"kwkarlwang/bufjump.nvim",
config = function()
require("bufjump").setup()
end
}
bufjump.nvim provides three options, forward
, backward
and on_success
. forward
and backward
are the keymappings to jump to the next and previous buffer in the jumplist respectively. The default keymappings for forward
and backward
are CTRL-n
and CTRL-p
respectively.
Default configuration:
use({
"kwkarlwang/bufjump.nvim",
config = function()
require("bufjump").setup({
forward = "<C-n>",
backward = "<C-p>",
on_success = nil
})
end,
})
You can also bind the function forward
and backward
as followed
local opts = { silent=true, noremap=true }
vim.api.nvim_set_keymap("n", "<M-o>", ":lua require('bufjump').backward()<cr>", opts)
vim.api.nvim_set_keymap("n", "<M-i>", ":lua require('bufjump').forward()<cr>", opts)
on_success
is a callback function that only executes after a successful backward or forward jump, which means that if there are no previous buffers in the jumplist, then on_success
will not be executed.
Suppose that you want to jump to the last cursor position after exiting the buffer instead of the last cursor position in the jumplist stack, you can set the on_success
function as followed:
use({
"kwkarlwang/bufjump.nvim",
config = function()
require("bufjump").setup({
forward = "<C-n>",
backward = "<C-p>",
on_success = function()
vim.cmd([[execute "normal! g`\"zz"]])
end,
})
end,
})
This will jump to the last cursor position before you left the buffer while also center the cursor to the middle of the screen. You can check :h last-position-jump
for more information.
Under the hood, this plugin uses native CTRL-o
and CTRL-i
to jump until the buffer is different from the current buffer. If there are no previous or next buffer, then the command does not jump at all.
When jumping to the previous buffer, it will jump to the last occurance in the jumplist that is different from the current buffer. Below is a simple illustration of the before and after position in the jumplist stack.
