leetcode.vim

Solve LeetCode problems in Vim!

This Vim plugin is inspired by skygragon/leetcode-cli.

Important Update! Please setup keyring for password safety:

Install keyring with pip3 install keyring --user
Remove g:leetcode_password from your configuration.
The first time you sign in, leetcode.vim will prompt for the password and store it in keyring.

Installation

Vim with +python3 feature is required. Install the pynvim package for Neovim:

pip3 install pynvim --user

Install keyring:

pip3 install keyring --user

Install the plugin:

Plug 'ianding1/leetcode.vim'

Quick Start

:LeetCodeList: browse the problems.
:LeetCodeTest: run the code with the default test case.
:LeetCodeSubmit: submit the code.
:LeetCodeSignIn: manually sign in.

Key mappings

leetcode.vim doesn't bind any key mappings by default. Put the following lines to your .vimrc to set up the key mappings.

nnoremap <leader>ll :LeetCodeList<cr>
nnoremap <leader>lt :LeetCodeTest<cr>
nnoremap <leader>ls :LeetCodeSubmit<cr>
nnoremap <leader>li :LeetCodeSignIn<cr>

`g:leetcode_solution_filetype`

The preferred programming language.

Values: 'cpp', 'java', 'python', 'python3', 'csharp', 'javascript', 'ruby', 'swift', 'golang', 'scala', 'kotlin', 'rust'.

FAQ

I use Ubuntu and get errors when signing in. How can I fix it?

Ubuntu users might see the error message below when signing in.

    raise InitError("Failed to unlock the collection!")
keyring.errors.InitError: Failed to unlock the collection!

It's caused by the misconfiguration of python-keyring. One way to fix it is to create a file ~/.local/share/python_keyring/keyringrc.cfg with the following content:

[backend]
default-keyring=keyring.backends.Gnome.Keyring

Why can't I test the problem/submit the problem/list the problems?

~~Once you sign in on your browser in LeetCode website, the LeetCode session in Vim get expired immediatelly. Then you need to sign in again in Vim before doing other things.~~ (No longer having this problem)

Why can't I test and submit solutions?

According to issue #5, if the email address is not active, then you can only login and download problems, but cannot test and submit any code.
