leetcode.vim

Solve LeetCode problems in Vim!

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

Attention: Recently LeetCode used Google reCAPTCHA to enhance security, prohibiting automatic login through LeetCode API.

The new login procedure needs you to login in your browser first so that leetcode.vim can read the LeetCode session cookie from the browser's cookie storage.

Supported browsers are: Chrome, Firefox. Safari is not supported yet.

The one-time setup:

1. Install keyring and browser-cookie3:

pip3 install keyring browser-cookie3 --user

2. Set g:leetcode_browser to 'chrome' or 'firefox'.

Thanks @zhuopro (see #25) for his brilliant idea!

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.

I got some errors like "ModuleNotFoundError: No module named 'keyring.util.escape'"

This solution worked for me:

pip3 install --upgrade keyrings.alt
