krzysztofzablocki/Sourcery
Sourcery is a code generation tool for Swift that parses source code using SwiftSyntax to produce boilerplate implementations for common patterns such as Equatable, Hashable, Codable, and mocking. It supports multiple template engines, including Stencil, JavaScript (EJS), and native Swift templates, allowing users to define custom code generation logic. The system provides built-in templates for standard protocols, type introspection, and Linux compatibility, while also supporting custom plugin integration via Swift Package Manager.

About this page
- The description of this project is derived from its own commit history, not from its README.
- The score is its highest published measurement, taken on 3 August 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
- Measured at commit f9d80ddec1 — the exact code this score is about.
- Scored under rubric rubric-2026.08.18. Score the same commit under that rubric and you get the same number.
