The code default located

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

code layout:

The cache located

• Linux: ~/.local/share/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

---

~/.config/lcode/cookies.toml

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 leetcode.com/com 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.

You can checkout the info/tab3 in tui for ensure cookies is valid.

Todo

• Cache cookies.

lcode's Issues

Add more button in edit tab.

It can reduce some keymap and more explicit.

decrypt-cookies for macos,windows

Because I only have a Linux environment, the 'decrypt-cookies' crate only works on Linux.
We need someone to write and test it on other platforms.

Sometimes check-in is not judged correctly.

The check-in result on leetcode com and cn websites differ require further observation.

Separate cookies

I think the cookies need be separated into other file,prevent users push cookies to github's dotfile repository.
But I have no motivation now.

Progress bar

Need to re-implement the progress bar
