Use the w, e, b motions like a spider. Move by subwords and skip insignificant punctuation.
Lua implementation of CamelCaseMotion. Works in normal, visual, and operator-pending mode. Works with counts.
The w, e, b (and ge) motions work the same as the default ones by vim, except for two differences:
The movements happen by subwords, meaning it stops at the sub-parts of a CamelCase (or SCREAMING_SNAKE_CASE or kebab-case) variable.
-- positions vim's `w` will move to
local myVariableName = FOO_BAR_BAZ
-- ^ ^ ^
-- positions spider's `w` will move to
local myVariableName = FOO_BAR_BAZ
-- ^ ^ ^ ^ ^ ^ ^A sequence of one or more punctuation characters is considered significant if it is surrounded by whitespace and does not include any non-punctuation characters.
foo == bar .. "baz"
-- ^ ^ significant punctuation
foo:find("a")
-- ^ ^ ^ insignificant punctuationThis speeds up the movement across the line by reducing the number of mostly unnecessary stops.
-- positions vim's `w` will move to
if foo:find("%d") and foo == bar then print("[foo] has" .. bar) end
-- ^ ^^ ^ ^^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ -> 21
-- positions spider's `w` will move to
if foo:find("%d") and foo == bar then print("[foo] has" .. bar) end
-- ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ -> 14If you prefer to use this plugin only for subword motion, you can disable this feature by setting skipInsignificantPunctuation = false in the .setup() call.
Note
vim'siskeywordoption is ignored by this plugin.
For an alternative iw text object that considers CamelCase word parts, check out the "subword" text object of nvim-various-textobjs.
-- packer
use { "chrisgrieser/nvim-spider" }
-- lazy.nvim
{ "chrisgrieser/nvim-spider", lazy = true },No keybindings are created by default. Below are the mappings to replace the default w, e, and b motions with this plugin's version of them.
Note that for dot-repeat to work properly, you have to use a <cmd> mapping that calls the plugin function, not a lua function calling it!
-- Keymaps
vim.keymap.set({"n", "o", "x"}, "w", "<cmd>lua require('spider').motion('w')<CR>", { desc = "Spider-w" })
vim.keymap.set({"n", "o", "x"}, "e", "<cmd>lua require('spider').motion('e')<CR>", { desc = "Spider-w" })
vim.keymap.set({"n", "o", "x"}, "b", "<cmd>lua require('spider').motion('b')<CR>", { desc = "Spider-w" })
vim.keymap.set({"n", "o", "x"}, "ge", "<cmd>lua require('spider').motion('ge')<CR>", { desc = "Spider-w" })The .setup() call is optional. Currently, its only option is to disable the skipping of insignificant punctuation:
-- default values
require("spider").setup({
skipInsignificantPunctuation = true
