Brush leetcode under the terminal


  • Open the editor of your choice for editing.
  • Filter based on the category of the question.
  • Fuzzy search.
  • Test and submit the code.
  • Modify the test case.
  • Automatically get cookies to eliminate the need for manual copying from the browser, power by decrypt-cookies.



  • sqlite
  • libsecret (Linux Optional)
  • libdbus (Linux notify)
  • mdcat (render markdown)


  • gcc
  • pkg-config (when without cross feature)
  • libdbus-1-dev (when without cross feature)

You can use any of the following methods to install


add ~/.cargo/bin to your $PATH

cargo binstall lcode
  • Archlinux can use AUR helper install

AUR contains completion scripts packaged for bash, zsh, and fish.

yay -S lcode-bin
# or
paru -S lcode-bin


  • Build by yourself
rustup default nightly
cargo install --locked --force lcode
# or
# cargo install --features cross --locked --force lcode

Update lcode

use cargo-update

cargo install-update --all


Generate configuration, manual modification of the configuration is also possible, and it will be automatically generated at runtime. Without -c, it will be generated in English.

lcode gencon -c

Synchronize basic data first.

lcode S

View the documentation for assistance.

lcode -h

Begin selecting a question.

lcode fzy <edit>

Shell completion

# zsh
echo 'eval $(lcode --generate zsh)' >>~/.zshrc
# bash
echo 'eval $(lcode --generate bash)' >>~/.bashrc
# ...
zi ice lucid wait as'completion' blockf has'lcode'

The configuration located

  • Linux: ~/.config/lcode/
  • macos: ~/.config/lcode/
  • Windows: C:\Users\user\AppData\Roaming\lcode

The code default located

  • Linux: ~/.local/share/lcode/
  • macOS: ~/Library/Application Support/lcode
  • Windows: C:\Users\user\AppData\Local\lcode

code layout:

├── 1.cpp*
└── 1_test_case.txt*

The cache located

  • Linux: ~/.local/share/lcode/
  • macOS: ~/Library/Caches/lcode
  • Windows: C:\Users\user\AppData\Local\lcode

Cookies (Important)

[First, login leetcode in browser for generate cookies]

General you just need filled browser at ~/.config/lcode/config.toml.

When use the section,be careful not to clear cookies when closing the browser.

browser = "edge" # `chrome`, `edge`, `firefox`, `librewolf` etc.
# Not casesensitive, `eDgE` also ok.

The detail: decrypt-cookies


csrf = ""
session = ""

[cookies] section

  • If the two fields are not empty, use the content filled by the user. And not use other method to get cookies。

    • Fill in manually:

      Press F12 on the browser's page, click network. Find the Cookie field, copy the csrftoken=<$content>; and LEETCODE_SESSION=<$content>; copy the $content into the configuration.

  • If filled browser , will try to use the browser to get cookies.

  • If neither of the above two items is filled in, and then use this order Firefox -> Librewolf -> Chrome -> Edge -> Chromium -> Brave -> Yandex -> Vivaldi -> Opera -> OperaGX -> CocCoc try to get cookies.






translate = false
column = 4
num_sublist = 10
page_size = 25
editor = ["vim"]
lang = "rust"
code_dir = "/home/user/.local/share/lcode"
browser = ""

url_suffix = "com"

Here are the explanations for each field

Checkout the Cookies (Important) section above.

browser = ""

Boolean, default is false. Show translated content or not.

translate = false

When retrieving the submissionlist, how many columns should be displayed.

column = 4

How many recent entries of the submissionlist information should be displayed.

num_sublist = 10

How many questions should be displayed at once when interactively selecting a question.

page_size = 25

Fill in your editor, it will attempt to retrieve it from the environment variables $EDITOR and $VISUAL, otherwise it will default to vim.

Specifically, when the editor is one of the ones below, will vert split question and code.

  • vim
  • nvim
  • helix
editor = ["vim"]

You can add additional parameters at the end.

editor = ["vim", "--noplugin"]

Set your selected programming language.

lang = "rust"

Set the location for storing code and test cases. You can also starting with ~

code_dir = "/home/user/.local/share/lcode"
# or
code_dir = "~/.local/share/lcode"

Fill in com or cn, for set or

url_suffix = "com"

For better rust coding. It will add a Cargo.toml file

cargo_integr = true
