demicolon.nvim

In addition to repeating t/T/f/F motions, this plugin lets you repeat diagnostic jumps (e.g. ]d/[d) and nvim-treesitter-textobjects jumps (e.g. ]f/[f) with the ;/, keys.

This plugin also integrates with gitsigns.nvim.

demicolon.mp4

Installation

With lazy.nvim:

{
  'mawkler/demicolon.nvim',
  -- keys = { ';', ',', 't', 'f', 'T', 'F', ']', '[', ']d', '[d' }, -- Uncomment this to lazy load
  dependencies = {
    'nvim-treesitter/nvim-treesitter',
    'nvim-treesitter/nvim-treesitter-textobjects',
  },
  opts = {}
}

Usage

After pressing any of the keymaps below, demicolon.nvim lets you repeat them with ; and ,.

Vertical motions (t/T/f/F)

See :help t, :help T, :help f, and :help F respectively.

Diagnostic motions

By default, demicolon.nvim will create the diagnostic motion keymaps below. See Configuration for info on how to disable default keymaps.

Motion	Description
]d	Next diagnostic (any severity)
[d	Previous diagnostic (any severity)
]e	Next error
[e	Previous error
]w	Next warning
[w	Previous warning
]i	Next information
[i	Previous information
]h	Next hint
[h	Previous hint

Treesitter text-object motions

demicolon.nvim lets you repeat any nvim-treesitter-textobjects motion. For example: ]f to "jump to next function", ]c to "jump to next class", etc.

Note

To use treesitter text-objects you need to configure textobjects.move in nvim-treesitter-textobjects.

Configuration

Default options:

opts = {
  diagnostic = {
    -- See `:help vim.diagnostic.Opts.Float`
    float = {}
  },
  -- Create default keymaps
  keymaps = {
    -- Create `t`/`T`/`f`/`F` key mappings
    horizontal_motions = true,
    -- Create ]d/[d, etc. key mappings to jump to diganostics. See demicolon.keymaps.create_default_diagnostic_keymaps
    diagnostic_motions = true,
    -- Create `;` and `,` key mappings
    repeat_motions = true,
  },
  integrations = {
    -- Integration with https://github.com/lewis6991/gitsigns.nvim
    gitsigns = {
      enabled = true,
      keymaps = {
        next = ']c',
        prev = '[c',
      },
    },
  },
}

Custom jumps

You can create your own custom repeatable jumps using repeatably_do() in demicolon.jump. repeatably_do() takes a funcion as its first argument and options to be passed to that function as its second argument. Make sure that the options include a boolean forward field to determine whether the action should be forward or backward. Take a look at how I've implemented the gitsigns.nvim integration for inspiration.

eyeliner.nvim integration

eyeliner.nvim can highlight unique letters in words when you press t/T/f/F. Below is my recommended configuration for using eyeliner.nvim together with demicolon.nvim.

NOTE: make sure to set keymaps.horizontal_motions = false in your demicolon setup if you want to use this config.

return {
  'jinh0/eyeliner.nvim',
  -- keys = { 't', 'f', 'T', 'F' }, -- Uncomment this to lazy load eyeliner.nvim
  config = function()
    require('eyeliner').setup({
      highlight_on_key = true,
      default_keymaps = false,
      dim = true, -- Optional
    })

    local function eyeliner_jump(key)
      local forward = vim.list_contains({ 't', 'f' }, key)
      return function()
        require('eyeliner').highlight({ forward = forward })
        return require('demicolon.jump').horizontal_jump(key)()
      end
    end

    local nxo = { 'n', 'x', 'o' }
    local opts = { expr = true }

    vim.keymap.set(nxo, 'f', eyeliner_jump('f'), opts)
    vim.keymap.set(nxo, 'F', eyeliner_jump('F'), opts)
    vim.keymap.set(nxo, 't', eyeliner_jump('t'), opts)
    vim.keymap.set(nxo, 'T', eyeliner_jump('T'), opts)
  end
}

})

Here's the full list of available treesitter textobjects.

"I want ;/, to remember the direction of the original jump"

Neovim's default behaviour is for ;/, to remember the direction of the jump that they repeat. That means that if you for instance repeat a T motion (as opposed to t) with ; it will move you to the left. A lot of people prefer if ; always moves you to the right and , always to the left, which is how demicolon works by default.

If you prefer Neovim's default behaviour you can disable demicolon's default ;/, keymaps and remap them manually like this:

Click here to see the code

require('demicolon').setup({
  keymaps = {
    repeat_motions = false,
  },
})

local ts_repeatable_move = require('nvim-treesitter.textobjects.repeatable_move')
local nxo = { 'n', 'x', 'o' }

vim.keymap.set(nxo, ';', ts_repeatable_move.repeat_last_move)
vim.keymap.set(nxo, ',', ts_repeatable_move.repeat_last_move_opposite)

The treesitter portion of this plugin is just a wrapper over nvim-treesitter-textobjects. Credit to them for making an awesome plugin!
