quicksheet-hackage

A QuickSheet extension for looking up Haskell packages on Hackage.

Type hackage: <package> in a QuickSheet cell to see version, synopsis, author, category, license, and homepage — right on your desktop wallpaper.

Usage

Cell value	Result
hackage: aeson	Latest version, synopsis, author, license, links for aeson
hackage: text	Package info for text
hackage: search json	Top packages matching "json"
hackage: search parser combinator	Search by multiple terms

Example output

  Version:   2.3.0.0  (102 total)
  Synopsis:  Fast JSON parsing and encoding
  Author:    Bryan O'Sullivan <bos@serpentine.com>
  Category:  Text, Web, JSON

  Hackage:   hackage.haskell.org/package/aeson

Install

ext: github:cemheren/quicksheet-hackage

Paste this into any QuickSheet cell. QuickSheet will clone and activate the extension automatically.

Requirements

• QuickSheet desktop or TUI mode
• .NET 9 SDK (for building the extension)
• Internet access (fetches from hackage.haskell.org — free, no API key)

How it works

• Package lookup: queries hackage.haskell.org/package/<name>.json for version history, then parses the .cabal file for metadata
• Search: queries the Hackage search endpoint and parses results
• Cache: 30-minute in-memory cache to avoid redundant requests
• Protocol: JSONL stdin/stdout as per QuickSheet extension spec
