Introduction

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

Usage

Execute leetcode command, and in problem list buffer:

Keymap	Description
o	show current problem
O	show problem by prompting problem id
v	view the current problem
V	view a problem by prompting problem id
b	show the current problem in browser
B	show a problem by problem id in browser
c	start coding the current problem
C	start coding a problem by problem id
s	filter problems by regex
t	filter problems by tag
T	toggle tag display
d	filter problems by difficulty
r	reset filters
P	toggle paid problems display
g	refresh without fetching from LeetCode
G	refresh all problems
L	change prefer language
RET	show current problem
TAB	view current problem

Press <RET>, show problem detail, move cursor to "solve it", press <RET> again, start coding!
After finishing your code, you can edit testcase and execute leetcode-try or execute leetcode-submit.

In leetcode-solution-mode, you will have:

Keymap	Description
C-c C-t	run code with testcase
C-c C-s	submit
C-c C-r	restore window layout

You can also disable IDE-like features by adding hook to leetcode-solution-mode-hook:

(add-hook 'leetcode-solution-mode-hook
          (lambda() (flycheck-mode -1)))

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

Clone this repository and install all dependencies
Move it to your load-path
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")

Work with Org Mode

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"))]

Debug

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