Domain Specific Language for Modular Knitting Pattern Definitions: Purl

TL;DR

Purl is a domain-specific language designed for modular, reusable knitting pattern definitions and verification, offering a more concise syntax than standard notation with an implemented compiler.

Contribution

It introduces a new language for knitting patterns that enables modularity and reuse, extending standard notation with additional constructs.

Findings

Purl supports pattern reuse and modularity.

The language is more terse than standard notation.

An implementation of a compiler for Purl is provided.

Abstract

Purl is a language to be used for modular definition and verification of knitting patterns. The syntax is similar to the standard knitting pattern notation provided by the Craft Yarn Council. Purl provides constructs not available in the standard notation to allow reuse of segments of patterns. This report describes the basics of knitting and hand-knitting patterns. A knitting pattern language more terse than the standard notation is presented with the implementation of a compiler to this standard.
