🚀 Usage

This plugin can be initiated in two ways:

• To start leetcode.nvim, simply pass arg as the first and only Neovim argument

  nvim leetcode.nvim
  

• (Experimental) Alternatively, you can use :Leet command to open leetcode.nvim within your preferred dashboard plugin. The only requirement is that Neovim must not have any listed buffers open.

Switching between questions

To switch between questions, use Leet tabs

🍴 Recipes

💤 lazy loading with lazy.nvim

Warning

opting for either option makes the alternative launch method unavailable due to lazy loading

• with arg

  local leet_arg = "leetcode.nvim"

  {
      "kawre/leetcode.nvim",
      lazy = leet_arg ~= vim.fn.argv()[1],
      opts = { arg = leet_arg },
  }

• with :Leet

  {
      "kawre/leetcode.nvim",
      cmd = "Leet",
  }
