Introduction

LeetCode brings you offer, and now Emacs brings you LeetCode!

Usage

1. Execute leetcode command, and in problem list buffer:

Keymap	Description
n	cursor move down
p	cursor move up
l	change prefer language
s	filter problems by regex
t	filter problems by tag
T	toggle tag display
d	filter problems by difficulty
/	clear filters
g	refresh without fetching from LeetCode
G	refresh all data
RET	show current problem description
TAB	view current problem description

More advanced navigation hotkeys can be found here.

2. Press <RET>, show problem description, move cursor to "solve it", press <RET> again, start coding!

3. After finishing your code, you can edit testcase and execute leetcode-try or execute leetcode-submit.

Advanced Navigation

Here are some advanced navigation hotkeys that may be useful in problem list buffer:

Keymap	Command	Description
o	leetcode-show-problem	show/open the current problem
O	leetcode-show-current-problem	show/open a problem by id
v	leetcode-view-problem	view the current problem
V	leetcode-view-current-problem	view a problem by id
b	leetcode-show-problem-in-browser	show the current problem in browser
B	leetcode-show-current-problem-in-browser	show a problem by id in browser
c	leetcode-solve-problem	start coding the current problem
C	leetcode-solve-current-problem	start coding a problem by id

Installation

• Vanilla Emacs: package-install it from melpa directly
• Spacemacs: leetcode-emacs-layer

LeetCode do not allow third party login, one workaround is restore LeetCode session from local Firefox or Chrome cookies. By default, this package will install a Python3 package called my_cookies, or you can install it manually: pip3 install my_cookies.

Since we are using shr.el to render HTML, you may also want to look at shrface.

Manually

1. Clone this repository and install all dependencies
2. Move it to your load-path
3. Require it in your emacs config

Configuration

You can set your preferred LeetCode programming language and SQL by setting leetcode-prefer-language and leetcode-prefer-sql:

If you prefer not to see problems' tags in the *leetcode**buffer by default. set leetcode-prefer-tag-display to nil

(setq leetcode-prefer-language "python3")
(setq leetcode-prefer-sql "mysql")

All supported languages can be found in variable leetcode--lang-suffixes.

You can save solution by setting leetcode-save-solutions:

(setq leetcode-save-solutions t)
(setq leetcode-directory "~/leetcode")

Debug

Call leetcode-toggle-debug, log will output in *leetcode-log* buffer.

Contributing

Please submit PR to develop branch.

Added filter to exclude paid only questions and leetcode-show-problem-by-slug

Just use leetcode-toggle-paid-display to toggle if paid only should be shown.

leetcode-show-problem-by-slug will let you put to org files with a link in this format to show the question after the leetcode buffer is load like [elisp:(leetcode-show-problem-by-slug (leetcode--slugify-title "ZigZag Conversion"))]
