Intro

LeetCode + Codeforces, unified.

A port of the Java CPRunner terminal tool, rebuilt as a first-class VS Code extension. Open a folder, click the 🏁 icon in the Activity Bar, and your entire competitive-programming workflow — change, test, submit, and read — lives inside the editor.

🚀 Why Leet-Forces?

Before	After
🕐 Switch tabs between browser, editor, terminal, and problem page	⌨️ One keystroke to change problems
🧪 Manually copy sample I/O into your compiler	✅ Auto-run examples + saved failed cases locally
📋 Scrolling the problem page for the statement	📖 Rendered description panel beside your code
🔐 Credentials scattered across files	🔒 Live in VS Code SecretStorage — never in the workspace
💔 Retesting failed submissions by hand	🤖 Submit, then auto-capture the verdict and re-test failing cases

✨ Features

🔄 Change Problem

Enter a number, slug, or URL — LeetCode or Codeforces.

n / p — next / previous problem
d — LeetCode daily challenge
Smart URL parsing for both platforms

🧪 Test

Platform	How it runs
LeetCode	Runs on LeetCode's own judge — examples + your saved failed cases
Codeforces	Compiles and runs samples + custom tests locally (needs your compiler on `PATH`)

📤 Submit

Platform	Behavior
LeetCode	Submits directly and saves failing cases for later re-testing
Codeforces	Copies code to clipboard, opens the submit page, and tracks the verdict. Optionally posts directly via `cprunner.codeforces.submitMode`.

📖 Description

Problem statements render as a panel beside the editor — read, scroll, and code without leaving your flow.

🌐 Languages

12 languages shared by both sites. Choose with Choose Language or set cprunner.language.

🔐 Auth

Logins live in VS Code SecretStorage, not in the workspace. An old .cprunner/auth.json is imported automatically once.
