case-dial.nvim

A simple Neovim plugin that cycles through case styles with one keypress.

One feature. One keymap. Zero config required.

Installation

lazy.nvim

{ "h3pei/case-dial.nvim", opts = {} }

That's it. Press <C-\> on any word and it just works.

Usage

my_variable → MyVariable → myVariable → MY_VARIABLE → my-variable → my_variable

• Normal mode: Place cursor on a word and press <C-\>
• Visual mode: Select text and press <C-\>

Features

• Single keymap to cycle through case styles
• Supports 5 case styles: snake_case, PascalCase, camelCase, CONSTANT_CASE, kebab-case
• Works in Normal and Visual mode
• No configuration needed (but customizable if you want)

Configuration (Optional)

Default settings work for most users. Customize only if needed:

require("case-dial").setup({
  -- Change case order
  cases = { "snake", "camel" },  -- Only these two

  -- Change keymap
  keymap = "<leader>cc",
})

Manual Keymap Setup

Disable default keymap and define your own:

require("case-dial").setup({
  keymap = false,
})

vim.keymap.set("n", "<leader>cd", function()
  require("case-dial").dial_normal()
end, { desc = "Dial case" })

vim.keymap.set("v", "<leader>cd", function()
  require("case-dial").dial_visual()
end, { desc = "Dial case" })
