nvim-treesitter-textobjects

Create your own textobjects using tree-sitter queries!

Installation

You can install nvim-treesitter-textobjects with your favorite package manager, or using the default pack feature of Neovim!

Using a package manager

If you are using vim-plug, put this in your init.vim file:

Plug 'nvim-treesitter/nvim-treesitter'
Plug 'nvim-treesitter/nvim-treesitter-textobjects'

Text objects: select

Define your own text objects mappings similar to ip (inner paragraph) and ap (a paragraph).

lua <<EOF
require'nvim-treesitter.configs'.setup {
  textobjects = {
    select = {
      enable = true,
      keymaps = {
        -- You can use the capture groups defined in textobjects.scm
        ["af"] = "@function.outer",
        ["if"] = "@function.inner",
        ["ac"] = "@class.outer",
        ["ic"] = "@class.inner",

        -- Or you can define your own textobjects like this
        ["iF"] = {
          python = "(function_definition) @function",
          cpp = "(function_definition) @function",
          c = "(function_definition) @function",
          java = "(method_declaration) @function",
        },
      },
    },
  },
}
EOF

Text objects: swap

Define your own mappings to swap the node under the cursor with the next or previous one, like function parameters or arguments.

lua <<EOF
require'nvim-treesitter.configs'.setup {
  textobjects = {
    swap = {
      enable = true,
      swap_next = {
        ["<leader>a"] = "@parameter.inner",
      },
      swap_previous = {
        ["<leader>A"] = "@parameter.inner",
      },
    },
  },
}
EOF

Text objects: move

Define your own mappings to jump to the next or previous text object. This is similar to ]m, [m, ]M, [M Neovim's mappings to jump to the next or previous function.

lua <<EOF
require'nvim-treesitter.configs'.setup {
  textobjects = {
    move = {
      enable = true,
      goto_next_start = {
        ["]m"] = "@function.outer",
        ["]]"] = "@class.outer",
      },
      goto_next_end = {
        ["]M"] = "@function.outer",
        ["]["] = "@class.outer",
      },
      goto_previous_start = {
        ["[m"] = "@function.outer",
        ["[["] = "@class.outer",
      },
      goto_previous_end = {
        ["[M"] = "@function.outer",
        ["[]"] = "@class.outer",
      },
    },
  },
}
EOF

Textobjects: LSP interop

• peek_definition_code: show textobject surrounding definition as determined using Neovim's built-in LSP in a floating window. Press the shortcut twice to enter the floating window (when https://github.com/neovim/neovim/pull/12720 or its successor is merged)

lua <<EOF
require'nvim-treesitter.configs'.setup {
  textobjects = {
    lsp_interop = {
      enable = true,
      peek_definition_code = {
        ["df"] = "@function.outer",
        ["dF"] = "@class.outer",
      },
    },
  },
