The go-to CLI tool for programming competitions setters.

AI Disclaimer
This repo was written until 2026 (~1400 commits) without the use of AI. Thus, the meaty part of the tool was written by a human that (hopefully) know what they're doing. Using AI, though, was proved to be much more efficient and less error prone if a human was kept in the loop. All AI features developed in this tool pass through a PR review and are carefully reviewed by the owner. This helps the owner maintain the project with less time, and implement more useful features in an efficient way (UI features, nice-to-have features, etc).
The owner plans to NOT USE AI for the execution engine of the tool: running solutions, generating tests, etc. These are critical parts of the tool that don't need to change that much, and should be kept stable.
Overview
rbx is a CLI tool that empowers setters from the competitive programming community.
A flexible setting tool, as powerful as Polygon, right on your terminal.
Features
- 🧱 Structure: describe your problem or contest structure with the use of YAML configuration files.
- 🤖 Generation: provides a simple way to describe your whole testset, including both manually added and generated testcases.
- 🔨 Testing: provides commands for automatically running correct and incorrect solutions against the testcases of your problem, automatically judging whether the verdict was as expected or not.
- ✅ Verify: checks if your testcases and solutions are strictly conformant with the use of validators and unit tests.
- 📝 Statements: provides tooling for writing and building statements, also ensuring they're easily synchronized with your testset.
