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"

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.

default imports

You can also pass before = true to inject default imports for the language. Supported languages are python, python3, java

Access default imports via require("leetcode.config.imports")

injector = { ---@type table<lc.lang, lc.inject>
    ["python3"] = {
        before = true
    },
    ["cpp"] = {
        before = { "#include <bits/stdc++.h>", "using namespace std;" },
        after = "int main() {}",
    },
    ["java"] = {
        before = "import java.util.*;",
    },
}

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 https://github.com/3rd/image.nvim/issues/62#issuecomment-1778082534

---@type boolean
image_support = false,

🚀 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

Sign In

It is required to be signed-in to use leetcode.nvim

🍴 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",
  }

🧩 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
