arg

Argument for Neovim

---@type string
arg = "leetcode.nvim"

See usage for more info

lang

Language to start your session with

---@type lc.lang
lang = "cpp"

available languages

Language	lang
C++	cpp
Java	java
Python	python
Python3	python3

cn

Use leetcode.cn instead of leetcode.com

cn = { -- leetcode.cn
    enabled = false, ---@type boolean
    translator = true, ---@type boolean
    translate_problems = true, ---@type boolean
},

storage

storage directories

---@type lc.storage
storage = {
    home = vim.fn.stdpath("data") .. "/leetcode",
    cache = vim.fn.stdpath("cache") .. "/leetcode",
},

plugins

plugins list

---@type table<string, boolean>
plugins = {
    non_standalone = false,
},

logging

Whether to log leetcode.nvim status notifications

---@type boolean
logging = true

injector

Inject code before or after your solution, injected code won't be submitted or run.

Imports will be injected at the top of the buffer, automatically folded by default.

injector = { ---@type table<lc.lang, lc.inject>
    ["python3"] = {
        imports = function(default_imports)
            vim.list_extend(default_imports, { "from .leetcode import *" })
            return default_imports
        end,
        after = { "def test():", "    print('test')" },
    },
    ["cpp"] = {
        imports = function()
            -- return a different list to omit default imports
            return { "#include <bits/stdc++.h>", "using namespace std;" }
        end,
        after = "int main() {}",
    },
},

picker

Supported picker providers are:

• snacks-picker
• fzf-lua
• telescope
• mini-picker

If provider is nil, leetcode.nvim will try to resolve the first available one in the order above.

---@type lc.picker
picker = { provider = nil },

hooks

List of functions that get executed on specified event

hooks = {
    ---@type fun()[]
    ["enter"] = {},

    ---@type fun(question: lc.ui.Question)[]
    ["question_enter"] = {},

    ---@type fun()[]
    ["leave"] = {},
},

theme

Override the default theme.

Each value is the same type as val parameter in :help nvim_set_hl

---@type lc.highlights
theme = {
    ["alt"] = {
        bg = "#FFFFFF",
    },
    ["normal"] = {
        fg = "#EA4AAA",
    },
},

image support

Whether to render question description images using image.nvim

Warning

Enabling this will disable question description wrap, because of 3rd/image.nvim#62 (comment)

---@type boolean
image_support = false,

📋 Commands

Leet opens menu dashboard

• menu same as Leet

• exit close leetcode.nvim

• console opens console pop-up for currently opened question

• info opens a pop-up containing information about the currently opened question

• tabs opens a picker with all currently opened question tabs

• yank yanks the code section

• lang opens a picker to change the language of the current question

• run run currently opened question

• test same as Leet run

• submit submit currently opened question

• random opens a random question

• daily opens the question of today problem

• list opens a picker with all available leetcode problems

• open opens the current question in a default browser

• restore try to restore default question layout

• last_submit tries to replace the editor code section with the latest submitted code

• reset resets editor code section to the default snippet

• inject re-injects editor code, keeping the code section intact

• fold applies folding to the current question imports section

• desc toggle question description

  • toggle same as Leet desc

  • stats toggle description stats visibility

• cookie

  • update opens a prompt to enter a new cookie

  • delete deletes stored cookie and logs out of leetcode.nvim

• cache

  • update fetches all available problems and updates the local cache of leetcode.nvim

Some commands can take optional arguments. To stack argument values separate them by a ,

• Leet list

  Leet list status=<status> difficulty=<difficulty>
  

• Leet random

  Leet random status=<status> difficulty=<difficulty> tags=<tags>
  

🚀 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
  

• 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. To bypass this requirement use non_standalone plugin.

❓ FAQ

I keep getting cookie expired error

If you keep getting Your cookie may have expired, or LeetCode has temporarily restricted API access, it most likely means that LeetCode website is under heavy load and is restricting API access (mostly during contests).

All you can do is wait it out, try disabling a VPN if you’re using one, and if the problem is persistent, open an issue.

Switching between test cases

To switch between test cases, just press the number of the corresponding case:
1 for Case (1), 2 for Case (2), and so on.

Switching between questions

To switch between questions, use Leet tabs

I'm not getting LSP completions

Some languages require additional setup to get LSP completions.
For example, Rust needs extra configuration — see this issue.

💤 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(0, -1),
      opts = { arg = leet_arg },
  }

• with :Leet

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

🪟 Windows

If you are using Windows, it is recommended to use Cygwin for a more consistent and Unix-like experience.

🧩 Plugins

Non-Standalone mode

To run leetcode.nvim in a non-standalone mode (i.e. not with argument or an empty Neovim session), enable the non_standalone plugin in your config:

plugins = {
    non_standalone = true,
}

You can then exit leetcode.nvim using :Leet exit command
