Use command to move cursor like `^` and `$`, in NeoVim?

Question

As title. How to move the cursor with vim command :...? I want to make a toggle that achieves this behavior but I didn't find anywhere this is explained :(

Answer 1

Any of

• :normal! ^ (or 0, or $)
• the functions setpos, cursor, or setcursorcharpos

should do it.

OTOH, on the : line you need things like <C-b> and <C-e> (see :help cmdline-editing), or press <C-f> and use normal motions.

Answer 2

Update:

This ternary version for 0 ^ $ is much better. Please call me UX-magician :)

vim.api.nvim_set_keymap('n', '0', '<cmd>lua toggle_zero_goto_line_beginning()<CR>', NOREF_NOERR_TRUNC)
local __goto_line_beginning_value = 0
function _G.toggle_zero_goto_line_beginning()
  if (__goto_line_beginning_value == 0) then
    vim.cmd("exe 'normal! 0'")
    __goto_line_beginning_value = 1
  elseif (__goto_line_beginning_value == 1) then
    vim.cmd("exe 'normal! ^'")
    __goto_line_beginning_value = 2
  else
    vim.cmd("exe 'normal! $'")
    __goto_line_beginning_value = 0
  end
end

I just tried-n-error in Vim and turn it into neovim version:

vim.api.nvim_set_keymap('n', '0', '<cmd>lua toggle_zero_goto_line_beginning()<CR>', NOREF_NOERR_TRUNC)
local __at_beginning = false
function _G.toggle_zero_goto_line_beginning()
  if (not __at_beginning) then
    vim.cmd("exe 'normal! ^'")
    __at_beginning = true
  else
    vim.cmd("exe 'normal! $'")
    __at_beginning = false
  end
end
