How do I enable this when there's a *Markdown* file is opened, and disable this otherwise?

I tried the following. This does enable no-neck-pain. However, it jumps to the left buffer that no-neck-pain uses for padding, instead of the main document.

vim.api.nvim_create_autocmd({'BufEnter', 'BufWinEnter', 'BufLeave', 'BufWinLeave'}, {
  pattern = { '*.md' },
  command = ':NoNeckPain',
})

If relevant, if use this with bufferline.

Hey, considering you'd like this to be triggered anytime a buffer type changes, I guess something like this would do it

vim.api.nvim_create_autocmd({ "BufEnter" }, {
    pattern = "*",
    callback = function()
        vim.schedule(function()
            local filetype = vim.api.nvim_buf_get_option(0, "filetype")
            local enabled =  _G.NoNeckPain.state ~= nil and _G.NoNeckPain.state.enabled

            if (filetype == "markdown" and not enabled) or (filetype ~= "markdown" and enabled) then
                return vim.cmd("NoNeckPain")
            end
        end)
    end,
})

it basically disables nnp if it's enabled and we are entering a non-markdown buffer, or enables it if it's disabled and we are moving to a markdown buffer

I'll find a cleaner way to make it work natively by specifying filetypes!

A simple modification of the answer, so that neo-tree works:

vim.api.nvim_create_autocmd({ 'BufEnter' }, {
  pattern = '*',
  callback = function()
    vim.schedule(function()
      if _G.NoNeckPain == nil then
        return
      end

      local filetype = vim.api.nvim_buf_get_option(0, 'filetype')
      local enabled =  _G.NoNeckPain.state ~= nil and _G.NoNeckPain.state.enabled

      if
        (filetype == 'markdown' and not enabled) or
        (filetype ~= 'markdown' and filetype ~= 'neo-tree' and filetype ~= 'no-neck-pain' and enabled)
      then
        return vim.cmd('NoNeckPain')
      end
    end)
  end,
})

return {
  'shortcuts/no-neck-pain.nvim',
  opts = {
    mappings = {
      enabled = true,
    },
  },
}
