Standard Ranklist

Repository: algoux/standard-ranklist

This is the srk core. It includes:

• Specification documents
• TypeScript type definitions
• JSON Schema

For developers, it can be used to:

1. Import type declarations for building tools and applications in TypeScript:

npm install -D @algoux/standard-ranklist

import type * as srk from '@algoux/standard-ranklist';

const myRanklist: srk.Ranklist = { ... };

2. Use the JSON Schema for autocompletion and validation in JSON files, or integrate with other validation tools:

{
  "$schema": "http://json-schema.org/draft-07/schema#",
  "$id": "https://unpkg.com/@algoux/standard-ranklist@latest/schema.json",
  "contest": { ... },
  "problems": [ ... ],
  "series": [ ... ],
  "rows": [ ... ]
}

Renderer Component

Repository: algoux/standard-ranklist-renderer-component

A web rendering component for srk that renders ranklists. It has been used in:

• Multiple past editions of the CCPC official ranklist pages
• RankLand

→ See Renderer Component

Utils

Repository: algoux/standard-ranklist-utils

A utility library for srk that provides common data processing functions:

• Data validation
• Sorting and computation
• Bidirectional conversion between static ranklists and submission record lists
• Other utility functions

→ See Utils Library

Convert-to

Repository: algoux/standard-ranklist-convert-to

A format conversion tool that converts srk data into formats used by other platforms and tools, including:

• Codeforces Gym format
• Excel spreadsheets
• Virtual Judge Replay format

→ See Format Conversion

Typical Workflows

For developers, many scenarios are well-suited for the srk ecosystem, such as:

1. Production — Enhance your OJ, tools, or services by using native or converted srk data
2. Rendering — Use the Renderer component to display ranklists in your own applications
3. Analysis — Use Utils and Convert-to tools to extract and batch-process ranklist data
