Calling pcall in neovim lua scripts to avoid errors

Using pcall when calling vim functions like vim.api.nvim_win_close can prevent errors from stopping the execution of a Neovim script.

local success, error = pcall(vim.api.nvim_win_close, win_id, force)

if not success then

      print("Failed to close window: " .. error)

  end

Using pcall in this way offers several benefits:

1. Error handling: If nvim_win_close fails, the error will be caught and stored in the error variable instead of stopping the script execution.
2. Graceful failure: You can handle the error gracefully, such as by printing an error message or taking alternative actions.
3. Continued execution: Your script will continue running even if the window closing operation fails.

This approach is particularly useful when dealing with floating windows or in situations where you’re not certain if the window still exists when you try to close it.
