If you're tired of OJ platforms with their mobile-unfriendly IDEs, or if you've ever wanted to jot down a brilliant algorithm idea on your phone, then ACC IDE is just what you need 🤗.

ACC IDE is a native Android integrated development environment designed specifically for algorithm competitions. It aims to enhance the competitive programming experience on mobile devices by providing a feature-rich environment for writing, testing, and submitting algorithmic solutions 😋.

Project Structure

The project is built with native Android and includes the following main components:

Implemented Features

Editor Capabilities

• Syntax highlighting: Use textmate for syntax highlighting
• Code completion: Code completion based on CST (tree-siiter)
• Theme Support: Dark and light modes with appropriate syntax coloring
• Gesture Controls: Adjust font size through zoom gestures
• Line Numbers and Block Indentation: Visual aids for code structure

File Management

• File Browser: Side drawer with a list of available files
• Rename and Delete: File management tools with confirmation dialogs
• Automatic Saving: Changes are automatically saved to prevent data loss, with temporary files stored at /storage/emulated/0/Android/data/com.acc_ide/files and templates at /template

Customization

• Language Selection: Interface language can be changed in settings
• Theme Selection: Toggle between dark and light themes
• Font Size Control: Adjust editor font size from settings or with gestures
• Editor Preferences: Customize editor behavior through settings, such as cursor width and symbol panel display

Input/Output Panel

• Input/Output Panel: Manual input and output viewing
• GitHub Action Backend: Free runtime via GitHub Actions repository, supports C/C++, Java, and Python
• WASM-based Local Environment: WebAssembly-based compilation environment, though C++ may have some issues as there's no pre-compiled WASM
• Memory and Time Limits: Execution time (2s) and memory (512MB) restrictions via backend
• Execution Status Display: Shows code execution status and runtime (AC, WA, TLE, MLE, RE, CE, RS - Run Successful when no expected output provided), with highlighted compilation errors

Planned Features

Feature Improvements

• Android Error Lens: Highlight compilation errors in the editor
• LSP: Plan to adopt tree-sitter+LSP for precise syntax highlighting and semantic-level code completion
• Maintain/Optimize wasm-clang

competitive-companion Integration

• Android version of competitive-companion
• Import test cases directly from problem statements
• Support for major competitive programming platforms:
  • Codeforces
  • AtCoder
  • Luogu
  • Niuke

Installation

• Download the latest version from releases
• Or clone the repository locally, open it with Android Studio, and run the project
