Introduction

XCPC Statement Generator is an open-source, browser-based application designed specifically for creating XCPC-style contest statements. Built with React, TypeScript, and powered by Typst (a modern typesetting system), this tool allows contest organizers to edit problem statements from various formats(Markdown, LaTeX and Typst) and export them as formatted PDFs that closely mirror the style of major competitive programming competitions in China (or competitions that use olymp.sty to create contest statements).

You can try XCPC Statement Generator on This Website, or get the source code on GitHub

Features

• Pure Browser-Based Operation: It runs entirely in your browser, simply open the web application.
• Support Polygon Packages: The tool supports importing Polygon contest packages. Contest organizers who use the Polygon system for problem management can directly import their exported ZIP files, automatically parsing problem statements, examples, and metadata.
• Multi-Format Support: XCPC Statement Generator supports three popular problem statement formats: Markdown, LaTeX and Typst.
• Real-Time Preview: Thanks to Typst, as you write or edit problem statements, you can instantly see how they will appear in the final PDF, ensuring what you see is what you get.
