Usage

Hold Control (or Opt, if you're on a Mac) + Left (or h, if you're a neovim purist) to jump to the closest symbol, beginning of word, or uppercase character inside a word that is on the left of the current cursor position. Use <Right> (or l) to move to the right, using the same logic.

Hold Control (or Opt) + Backspace to delete what's on the left of the cursor, using the same smart logic for the jump; use Del to delete, instead, what's on its right.

Installation

Lazy

Important

The plugin must NOT be lazy loaded!

{
  "neovim-idea/camelhumps-nvim",
  lazy = false,
}

Packer

use {
  "neovim-idea/camelhumps-nvim",
}

Plug

Plug "neovim-idea/camelhumps-nvim"

Setup

In your config function, simply add the following lines:

local camelhumps = require("camelhumps").setup()
vim.keymap.set({ "n", "i", "v" }, "<M-Left>", camelhump.left, { noremap = true, silent = true })
vim.keymap.set({ "n", "i", "v" }, "<M-Right>", camelhump.right, { noremap = true, silent = true })
vim.keymap.set({ "n", "i", "v" }, "<M-BS>", camelhump.left_delete, { noremap = true, silent = true })
vim.keymap.set({ "n", "i", "v" }, "<M-Del>", camelhump.right_delete, { noremap = true, silent = true })

As you might have guessed, the plugin exposes four, high level methods:

• left(), to move the cursor to the left
• right(), to move the cursor to the right
• left_delete(), to delete text on the left of the cursor
• right_delete(), to delete text on the right of the cursor

Development

Install lua, luarocks and busted, usually via brew as such:

brew install lua luarocks busted

Then, you can run the tests like so

chmod +x run_tests.sh
./run_tests.sh

Todo

• recognise enums such as FOO_BAR_BAZ ad jump them altogether
• have a round of checks on the tests and make sure to document behaviours diverging from IntelliJ
• left/right{_delete} have quite some duplicate code: make it centralized
• wrap internal functions that are testsed into a _private module, and export them if _G.testing_enabled == true
• make run_tests.sh detect if deps are already installed and, if so, skip the process
