Vaiaksh CP Runner is a lightweight, low-latency competitive programming runner for Visual Studio Code, engineered for C++, Java, and Python. It provides an integrated side panel with persistent custom input, live output rendering, execution metrics (time/memory), and automated Time Limit Exceeded (TLE) safeguards.
Features
Multi-Language Support: Compiles and runs C++ (g++), Java (javac/java), and Python (python3) with zero manual boilerplate configuration.
Interactive Side Panel: Dedicated side-by-side view with custom input buffering and formatted output streaming.
TLE Protection: Configurable execution timeouts kill hanging processes or infinite loops via SIGKILL without locking up your editor.
Execution Metrics: Accurate tracking of runtime in milliseconds, peak resident memory usage (via /usr/bin/time), and exit codes.
Output Buffer Safeguard: Automatic output truncation past 50,000 characters to protect VS Code from UI freezing during infinite print loops.
Requirements
Ensure runtimes are available in your system PATH:
C++: g++ (GCC / MinGW)
Java: javac and java (JDK 8+)
Python: python3 (or python on Windows)
Extension Settings
All configurations live under the vaiaksh-cp-runner namespace:
vaiaksh-cp-runner.autoOpenUI: Automatically open the CP Runner side panel on workspace activation when CP files are detected (default: false).
vaiaksh-cp-runner.panelWidth: Percentage of the screen width allocated to the runner panel (default: 30, min: 10, max: 90).
vaiaksh-cp-runner.timeout: Process execution timeout in milliseconds before triggering TLE termination (default: 5000).
Keybindings
Run Code: Ctrl + Enter (Windows/Linux) / Cmd + Enter (macOS)
Toggle Panel: Ctrl + Shift + C (Windows/Linux) / Cmd + Shift + C (macOS)
