elycode is a one-stop VS Code extension for competitive programming practice. It enables code management, testing, and submission in a single workflow.

Key Features

Import: Import problems from contest URLs without login and without a browser plugin
Test: Support sample testing and comparison with sample answers, and add custom test cases
Submit: Support jumping to the problem submission website and viewing historical submission records
Display: Present problem information, samples, contests, and submission statistics clearly in the sidebar
Code: Automatically generate corresponding C++ source files (.cpp), auto-detect GCC, and support automatic GCC download/configuration on Windows (more programming languages will be supported in future releases)
Theme: Support VS Code light and dark themes

Quick Start

Open VS Code and install the elycode extension from the Extensions Marketplace.
Open the elycode sidebar view and you can click the button to add the contest you need.
In the pop-up input box, enter the URL of the contest you want to add. The URL must contain the ID of the contest.
You can use the sidebar view provided by elycode to manage and view contest problems, and you can also submit solutions for them.
By clicking the problem name, you can open the coding interface. The left side is the code area where you can implement your algorithm, and the right side is the view area that displays all problem information.

The view area also supports adding test cases and running sample cases and custom cases.
Optional: If you want to display related data such as submission history, you should configure the usernames for the corresponding platforms. See the Configuration section for elycode.platform.codeforces.UserName and elycode.platform.luogu.UserName. elycode will also update the data every elycode.platform.updateContestInfoInterval(seconds) seconds, and you can manually refresh it by using the button.

Development and Build

This project is built with TypeScript.

npm install
npm run compile
npm run watch

npm run compile: Compile the TypeScript source.
npm run watch: Start TypeScript watch mode.

Since the VS Code extension development environment is configured, you can also test and develop the extension in the integrated development environment through the VS Code launch configuration.
