Installation

Variant 1: Have nvim-various-textobjs set up all the keybindings from the table above for you.

-- lazy.nvim
{
	"chrisgrieser/nvim-various-textobjs",
	event = "VeryLazy",
	opts = { 
		keymaps = {
			useDefaults = true 
		}
	},
},

-- packer
use {
	"chrisgrieser/nvim-various-textobjs",
	config = function () 
		require("various-textobjs").setup({ 
			keymaps = {
				useDefaults = true 
			}
		})
	end,
}

Variant 2: Use your own keybindings. See the Configuration section for information on how to set your own keymaps.

-- lazy.nvim
{
	"chrisgrieser/nvim-various-textobjs",
	keys = {
		-- ...
	},
},

-- packer
use { "chrisgrieser/nvim-various-textobjs" }

Tip

You can also use the keymaps.disabledDefaults config option to disable only some default keymaps.

Configuration

Options

The .setup() call is optional if you do not want to use the default keymaps.

-- default config
require("various-textobjs").setup {
	keymaps = {
		-- See overview table in README for the defaults. (Note that lazy-loading
		-- this plugin, the default keymaps cannot be set up. if you set this to
		-- `true`, you thus need to add `lazy = false` to your lazy.nvim config.)
		useDefaults = false,

		-- disable only some default keymaps, for example { "ai", "!" }
		-- (only relevant when you set `useDefaults = true`)
		---@type string[]
		disabledDefaults = {},
	},

	forwardLooking = {
		-- Number of lines to seek forwards for a text object. See the overview
		-- table in the README for which text object uses which value.
		small = 5,
		big = 15,
	},
	behavior = {
		-- save position in jumplist when using text objects
		jumplist = true, 
	},

	-- extra configuration for specific text objects
	textobjs = {
		indentation = {
			-- `false`: only indentation decreases delimit the text object
			-- `true`: indentation decreases as well as blank lines serve as delimiter
			blanksAreDelimiter = false,
		},
		subword = {
			-- When deleting the start of a camelCased word, the result should
			-- still be camelCased and not PascalCased (see #113).
			noCamelToPascalCase = true,
		},
		diagnostic = {
			wrap = true,
		},
	},

	notify = {
		icon = "󰠱", -- only used with notification plugins like `nvim-notify`
		whenObjectNotFound = true,
	},

	-- show debugging messages on use of certain text objects
	debug = false,
}

Use your own keybindings

If you want to set your own keybindings, you can do so by calling the respective functions. The function names correspond to the text object names from the overview table.

Note

For dot-repeat to work, you have to call the motions as Ex-commands. Using function() require("various-textobjs").diagnostic() end as third argument of the keymap will not work.

-- example: `U` for url textobj
vim.keymap.set({ "o", "x" }, "U", '<cmd>lua require("various-textobjs").url()<CR>')

-- example: `as` for outer subword, `is` for inner subword
vim.keymap.set({ "o", "x" }, "as", '<cmd>lua require("various-textobjs").subword("outer")<CR>')
vim.keymap.set({ "o", "x" }, "is", '<cmd>lua require("various-textobjs").subword("inner")<CR>')

For most text objects, there is only one parameter which accepts "inner" or "outer". The only exception is the indentation text object:

-- THE INDENTATION TEXTOBJ requires two parameters, the first for exclusion of 
-- the starting border, the second for the exclusion of ending border
vim.keymap.set(
	{ "o", "x" },
	"ii",
	'<cmd>lua require("various-textobjs").indentation("inner", "inner")<CR>'
)
vim.keymap.set(
	{ "o", "x" },
	"ai",
	'<cmd>lua require("various-textobjs").indentation("outer", "inner")<CR>'
)

Advanced usage / API

All text objects can also be used as an API to modify their behavior or create custom commands. Here are some examples:

Go to next occurrence of a text object

When called in normal mode, nvim-various-textobjs selects the next occurrence of the text object. Thus, you can easily create custom motions that go to the next occurrence of the text object:

local function gotoNextInnerNumber()
	require("various-textobjs").number("inner")
	local mode = vim.fn.mode()
	if mode:find("[Vv]") then -- only switches to visual when textobj found
		vim.cmd.normal { mode, bang = true } -- leaves visual mode
	end
end,

ii on unindented line should select entire buffer

Using a simple if-else-block, you can create a hybrid of the inner indentation text object and the entire-buffer text object, if you prefer that kind of behavior:

-- when on unindented line, `ii` should select entire buffer
vim.keymap.set("o", "ii", function()
	if vim.fn.indent(".") == 0 then
		require("various-textobjs").entireBuffer()
	else
		require("various-textobjs").indentation("inner", "inner")
	end
end)

Smarter gx

The code below retrieves the next URL (within the amount of lines configured in the setup call), and opens it in your browser. As opposed to vim's built-in gx, this is forward-seeking, meaning your cursor does not have to stand on the URL.

vim.keymap.set("n", "gx", function()
	-- select URL
	require("various-textobjs").url()

	-- plugin only switches to visual mode when textobj is found
	local foundURL = vim.fn.mode() == "v"
	if not foundURL then return end

	-- retrieve URL with the z-register as intermediary
	vim.cmd.normal { '"zy', bang = true }
	local url = vim.fn.getreg("z")
	vim.ui.open(url) -- requires nvim 0.10
end, { desc = "URL Opener" })

You could go even further: When no URL can be found by various-textobjs, you could retrieve all URLs in the buffer and select one to open.

vim.keymap.set("n", "gx", function()
	require("various-textobjs").url()
	local foundURL = vim.fn.mode() == "v"
	if foundURL then
		vim.cmd.normal('"zy')
		local url = vim.fn.getreg("z")
		vim.ui.open(url) -- requires nvim 0.10
		return
	end

	-- find all URLs in buffer
	local urlPattern = [[%l%l%l-://[^%s)"'`]+]]
	local bufText = table.concat(vim.api.nvim_buf_get_lines(0, 0, -1, false), "\n")
	local urls = {}
	for url in bufText:gmatch(urlPattern) do
		table.insert(urls, url)
	end
	if #urls == 0 then return end

	-- select one
	vim.ui.select(urls, { prompt = "Select URL:" }, function(choice)
		if not choice then return end
		vim.ui.open(url) -- requires nvim 0.10
	end)
end, { desc = "URL Opener" })

Delete surrounding indentation

Using the indentation text object, you can also create custom indentation-related utilities. A common operation is to remove the line before and after an indentation. Take for example this case where you are removing the foo condition:

-- before
if foo then
	print("bar") -- <- cursor is on this line
	print("baz")
end

-- after
print("bar")
print("baz")

The code below achieves this by dedenting the inner indentation text object (essentially running <ii), and deleting the two lines surrounding it. As for the mapping, dsi should make sense since this command is similar to the ds operator from vim-surround but performed on an indentation text object. (It is also an intuitive mnemonic: Delete Surrounding Indentation.)

vim.keymap.set("n", "dsi", function()
	-- select outer indentation
	require("various-textobjs").indentation("outer", "outer")

	-- plugin only switches to visual mode when a textobj has been found
	local indentationFound = vim.fn.mode():find("V")
	if not indentationFound then return end

	-- dedent indentation
	vim.cmd.normal { "<", bang = true }

	-- delete surrounding lines
	local endBorderLn = vim.api.nvim_buf_get_mark(0, ">")[1]
	local startBorderLn = vim.api.nvim_buf_get_mark(0, "<")[1]
	vim.cmd(tostring(endBorderLn) .. " delete") -- delete end first so line index is not shifted
	vim.cmd(tostring(startBorderLn) .. " delete")
end, { desc = "Delete Surrounding Indentation" })

Yank surrounding indentation

Similarly, you can also create a ysii command to yank the two lines surrounding an indentation text object. (Not using ysi, since that blocks surround commands like ysi)). Using nvim_win_[gs]et_cursor(), you make the operation sticky, meaning the cursor is not moved.

vim.keymap.set("n", "ysii", function()
	local startPos = vim.api.nvim_win_get_cursor(0)

	-- identify start- and end-border
	require("various-textobjs").indentation("outer", "outer")
	local indentationFound = vim.fn.mode():find("V")
	if not indentationFound then return end
	vim.cmd.normal { "V", bang = true } -- leave visual mode so the '< '> marks are set

	-- copy them into the + register
	local startLn = vim.api.nvim_buf_get_mark(0, "<")[1] - 1
	local endLn = vim.api.nvim_buf_get_mark(0, ">")[1] - 1
	local startLine = vim.api.nvim_buf_get_lines(0, startLn, startLn + 1, false)[1]
	local endLine = vim.api.nvim_buf_get_lines(0, endLn, endLn + 1, false)[1]
	vim.fn.setreg("+", startLine .. "\n" .. endLine .. "\n")

	-- highlight yanked text
	local ns = vim.api.nvim_create_namespace("ysi")
	vim.api.nvim_buf_add_highlight(0, ns, "IncSearch", startLn, 0, -1)
	vim.api.nvim_buf_add_highlight(0, ns, "IncSearch", endLn, 0, -1)
	vim.defer_fn(function() vim.api.nvim_buf_clear_namespace(0, ns, 0, -1) end, 1000)

	-- restore cursor position
	vim.api.nvim_win_set_cursor(0, startPos)
end, { desc = "Yank surrounding indentation" })

Indent last paste

The lastChange text object can be used to indent the last text that was pasted. This is useful in languages such as Python where indentation is meaningful and thus formatters are not able to automatically indent everything for you.

If you do not use P for upwards paste, "shift paste" serves as a great mnemonic.

vim.keymap.set("n", "P", function()
	require("various-textobjs").lastChange()
	local changeFound = vim.fn.mode():find("v")
	if changeFound then vim.cmd.normal { ">", bang = true } end
end

Limitations & non-goals

  • This plugin uses pattern matching, so it can be inaccurate in some edge cases.
  • The characterwise text objects do not match multi-line objects. Most notably, this affects the value text object.
  • nvim-treesitter-textobjects already does an excellent job when it comes to using Treesitter for text objects, such as function arguments or loops. This plugin's goal is therefore not to provide text objects already offered by nvim-treesitter-textobjects.
