越睡越困是什么原因

Question

I'm trying to create an autocmd that copies selected text in visual mode in Neovim (preferably when selecting text with the mouse and copy on mouse button release)

I've tried so far:

vim.api.nvim_create_autocmd({"ModeChanged"}, {
  pattern = "[vV\x16]*:*",
  callback = function()
    vim.cmd('"*y')
  end,
})

If I do a command ="echo 'test'" instead of callback I can see the text once selected then hitting Esc so the autocmd somewhat works.

Answer 1

Remark: "*y is not a command but a set of keystroke.

I would do:

vim.api.nvim_create_autocmd({"ModeChanged"}, {
  pattern = "[vV\x16]*:*",
  callback = function()
      text = ''
      for linenb=vim.fn.line("'<"), vim.fn.line("'>") do
          line = vim.fn.getline(linenb)

          first_col = 1
          first_line = linenb == vim.fn.line("'<")
          if first_line then
              first_col = vim.fn.col("'<")
          end

          last_col = -1
          last_line = linenb == vim.fn.line("'>")
          if last_line then
              last_col = vim.fn.col("'>")
          end
          line = string.sub(line, first_col, last_col)

          if last_col == -1 then
              line = line .. "\n"
          end

          text = text .. line
      end
      vim.fn.setreg('*', text)
  end,
})
