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 | | C | c | | C# | csharp | | JavaScript | javascript | | TypeScript | typescript | | PHP | php | | Swift | swift | | Kotlin | kotlin | | Dart | dart | | Go | golang | | Ruby | ruby | | Scala | scala | | Rust | rust | | Racket | racket | | Erlang | erlang | | Elixir | elixir | | Bash | bash |

cn

Use [leetcode.cn] instead of [leetcode.com][leetcode]

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.listextend(defaultimports, { "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][snacks.nvim]
• [fzf-lua][fzf-lua]
• [telescope][telescope.nvim]
• [mini-picker][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 nvimsethl

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

image support

[!NOTE]

Requires [image.nvim] v1.4.0+ which fixed text wrapping support (see https://github.com/3rd/image.nvim/pull/266)

---@type boolean
image_support = true,

📋 Commands

• 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.

[!WARNING]

Be sure to copy the Cookie from request headers, not the set-cookie from

response headers.

❓ 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.

🍴 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(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
