text-transform.nvim

Common text transformers for nvim - switch between camelCase, PascalCase, snake_case, and more!

⚡️ Features

Transform the current word or selection between multiple case types. Need to easily replace myVar with my_var or vice versa? This plugin is for you!

• Works on current word in Normal Mode
  • Will replace the current word selectable by ciw
• Works on selection in Visual Mode
  • Will replace only inside the selection
• Works on column selections in Visual Block Mode
  • Will detect if the block is a single column or multiple columns
    • If it's a single column, will replace the word under each cursor
    • If it's a selection with length, will replace only inside the selection ranges

Transformation	Example Inputs	Output
camelCase	my_var, my-var, MyVar	myVar
PascalCase	my_var, my-var, myVar	MyVar
snake_case	myVar, my-var, MyVar	my_var
kebab-case	my_var, myVar, MyVar	my-var
dot.case	my_var, my-var, MyVar	my.var
Title Case	my_var, my-var, MyVar	My Var
CONST_CASE	my_var, my-var, MyVar	MY_VAR

🚀 Getting started

To get started, install the plugin via your favorite package manager.

1. Use the following code to setup in any loaded .lua file

   require('text-transform').setup({
       -- custom settings
   })
   

2. Either make a selection using Visual mode, or just have your cursor stand on a desired word.

   Then, use the mapped key (default: <Leader>~) to open the transform options in a popup.

3. Select the desired transform and you're done!

⚙️ Configuration

Note

: The options are also available in Neovim by calling :h TextTransform.options

The following are the default options when none are configured by the user.

To merge any new config into the default, you can override only the keys you need, and leave the rest to use the defaults.

require("text-transform").setup({
  -- Prints useful logs about what event are triggered, and reasons actions are executed.
  debug = false,
  -- Keymap configurations
  keymap = {
    -- Keymaps to open the telescope popup. Set to `false` or `nil` to disable keymapping for
    -- the Telescope popup.
    -- You can always customize your own keymapping manually.
    telescope_popup = {
      -- Opens the popup in normal mode
      ["n"] = "<Leader>~",
      -- Opens the popup in visual/visual block modes
      ["v"] = "<Leader>~",
    },
  },
})

📝 Commands

The following commands are available for your use in your own mappings or for reference.

Command	Description
:TtTelescope | :TextTransform	Pops up a Telescope window with the available converters which will directly act on the selected text.
:TtCamel	Replaces selection with camelCase.
:TtConst	Replaces selection with CONST_CASE.
:TtDot	Replaces selection with dot.case.
:TtKebab	Replaces selection with kebab-case.
:TtPascal	Replaces selection with PascalCase.
:TtSnake	Replaces selection with snake_case.
:TtTitle	Replaces selection with Title Case.

⌨️⌨️ Keymaps

You can use the setup options to customize the default keymaps used to trigger the Telescope Popup.

To disable these automated mappings, pass nil or false to the containing table (e.g. telescope_popup) or to the keys themselves.

-- Disable entirely
require("text-transform").setup({
  keymap = {
    telescope_popup = nil,
  },
})
-- Disable just one keymap
require("text-transform").setup({
  keymap = {
    telescope_popup = {
      ["v"] = nil,
    },
  },
})

You can also create custom mappings to specific case conversions or to the Telescope popup yourself.

-- Trigger telescope popup
local telescope = require('text-transform.telescope')
vim.keymap.set("n", "<leader>~~", telescope.popup, { silent = true })

-- Trigger case converters directly
vim.keymap.set({ "n", "v" }, "<leader>Ccc", ":TtCamel",  { silent = true })
vim.keymap.set({ "n", "v" }, "<leader>Cco", ":TtConst",  { silent = true })
vim.keymap.set({ "n", "v" }, "<leader>Cdo", ":TtDot",    { silent = true })
vim.keymap.set({ "n", "v" }, "<leader>Cke", ":TtKebab",  { silent = true })
vim.keymap.set({ "n", "v" }, "<leader>Cpa", ":TtPascal", { silent = true })
vim.keymap.set({ "n", "v" }, "<leader>Csn", ":TtSnake",  { silent = true })
vim.keymap.set({ "n", "v" }, "<leader>Ctt", ":TtTitle",  { silent = true })
