@sidereus/cube-compress

A small Python module for compressing and decompressing .cube files. This repo also includes a frontend TypeScript version with the same format.

Install

npm install @sidereus/cube-compress

（前端用到的 fflate 会随包自动安装。）

Usage (Python)

from cube_compress import compress, decompress

compress("input.cube", "output.cubexs")
decompress("output.cubexs", "output.cube")

Usage (前端 TypeScript)

import { compress, decompress } from './cubeCompress';

// 压缩：输入 cube 文件字符串，输出字节数组
const cubeString = '...'; // 完整 .cube 文件内容
const bytes: Uint8Array = compress(cubeString);

// 解压：输入字节数组（.cubexs 或 compress 的输出），输出 cube 文件字符串
const restored: string = decompress(bytes);

• compress(cubeString: string): Uint8Array — 输入为 cube 文件字符串，输出为字节数组（与 Python 写出的 .cubexs 格式一致）。
• decompress(bytes: Uint8Array): string — 输入为字节数组，输出为 cube 文件字符串。

依赖：fflate（gzip 压缩/解压，自带 TypeScript 类型）。

Notes

• This is a Python script distributed via npm for convenience.
• You need Python and NumPy available in your environment.
• Compression is lossy (float32 -> 24-bit) and output formatting may differ from the original.
• compress() always writes .cubexs and decompress() always writes .cube.
