Vim Troubleshooting

When you run into problems run :checkhealth to see if it rings a bell.

Deal with big files

Sometimes neovim freezes when opening big files, one way to deal with it is to disable some functionality when loading them

local aug = vim.api.nvim_create_augroup("buf_large", { clear = true })

vim.api.nvim_create_autocmd({ "BufReadPre" }, {
  callback = function()
    local ok, stats = pcall(vim.loop.fs_stat, vim.api.nvim_buf_get_name(vim.api.nvim_get_current_buf()))
    if ok and stats and (stats.size > 100000) then
      vim.b.large_buf = true
      -- vim.cmd("syntax off") I don't yet need to turn the syntax off
      vim.opt_local.foldmethod = "manual"
      vim.opt_local.spell = false
      set.foldexpr = 'nvim_treesitter#foldexpr()' -- Disable fold expression with treesitter, it freezes the loading of files
      vim.b.large_buf = false
  group = aug,
  pattern = "*",

When it opens a file it will decide if it's a big file. If it is, it will unset the foldexpr which made it break for me.

Telescope's preview also froze the terminal. To deal with it I had to disable treesitter for the preview

  defaults = {
    preview = {
      enable = true,
      treesitter = false,

Telescope changes working directory when opening a file

In my case was due to a snippet I have to remember the folds:

  augroup remember_folds
    autocmd BufWinLeave * silent! mkview
    autocmd BufWinEnter * silent! loadview
  augroup END

It looks that it had saved a view with the other working directory so when a file was loaded the cwd changed. To solve it I created a new mkview in the correct directory.
