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 *" })

Supported picker providers are:
If provider is nil, leetcode.nvim will try to resolve the first
available one in the order above.
---@type lc.picker

π Usage
This plugin can be initiated in two ways:
-
To start leetcode.nvim, simply pass
arg
as the first and only Neovim argumentnvim leetcode.nvim -
Use
:Leetcommand 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 usenon_standaloneplugin.

β 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 youβre 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 β see this issue.
π΄ Recipes
π€ lazy loading with lazy.nvim
Warning
opting for either option makes the alternative
launch method unavailable due to lazy loading
-
with
arglocal 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", }
πͺ Windows
If you are using Windows,
it is recommended to use Cygwin for a more consistent and Unix-like experience.
π§© 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
