Is it possible to support HighlightColorsOff on a specific buffer only?

[nyngwang]

As title. I'm trying to support large files in nvim, and it will be good if this plugin can be disabled only on those large files.

update:

Is this plugin enabled by default? I have tried the following autocmd but it doesn't work. I still need to uninstall this plugin so that my Neovim won't get frozen after opening those large files.

vim.api.nvim_create_autocmd({ 'BufReadPre', 'FileReadPre' }, {
  pattern = '*',
  callback = function ()
    if vim.fn.getfsize(vim.fn.expand('%')) > 1024 * 1024 -- file size > 1 MB.
    then
      vim.cmd([[
        syntax off
        HighlightColorsOff
        " TSBufDisable highlight indent autotag incremental_selection
      ]])
    end
  end
})

Are you sure my plugin is the one at fault? My plugin will only process stuff that is being displayed by the buffer, so no matter if the file has millions of colors or millions of lines, the plugin should work blazing fast.

Sure. This is a little part of the log: (generated after opening a binary file that has a wrong extension .ts). I was using an example from nvim-treesitter/nvim-treesitter#1530. So to generate the file:

cat /dev/urandom | head -c 5242880 > bin.ts

Is it possible to share this file with me? Or is it something private?
This seems to be an actual plugin crash and not really related to performance 😅

You can generate it via this command: (assuming you have a linux system, in my case it's macOS)

cat /dev/urandom | head -c 5242880 > bin.ts
