zj-to-hydrooj

A tool designed to convert problem data from ZeroJudge (ZJSON) format to HydroOJ compatible format. It simplifies the migration process by automatically handling complex formatting and LaTeX expressions.

Installation

``bash
npm i zj-to-hydrooj
``

Features

* Seamless Conversion: Transition your problems from ZeroJudge to HydroOJ with ease.
* Format Support: Upload your data in either .zjson or .zip format.
* Note: Currently supports single file upload at a time.
* Rich Content Support: The converter intelligently handles:
* Markdown: Headers, Bold, Italic, Strikethrough, and Underline.
* Mathematics: Full support for LaTeX / KaTeX (inline and display mode).
* Layouts: Tables, lists, and horizontal rules.
* Media: Image embedding and link preservation.
* Automatic Author Linking: Automatically generates a link to the author's profile on the original platform (DanDanJudge).

Limitations

* Custom Colors: CSS-based custom text colors are currently not supported and will be rendered as plain text or default style.
* Upload Size: For files larger than 15MB, it is highly recommended to compress them into a .zip file before uploading to ensure better efficiency and stability.

Usage

2. Select the From JSON/ZIP Export option.
3. Upload your .zjson file or a .zip containing the problem data.
