From e500888b42b2827b459603347c515eed7bad06fe Mon Sep 17 00:00:00 2001 From: Petr Plenkov Date: Thu, 13 Aug 2026 03:02:09 +0200 Subject: [PATCH 1/6] v0 Wave D: Decorator authoring layer MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit New @sverka/decorators package — the third authoring surface. Uses TC39 standard decorators (TypeScript 5.0+, no experimentalDecorators). Decorators: - @pipeline: class decorator marking a Sverka pipeline - @step: field decorator for string shorthand or StepBuilder - @stepWithOptions(options): factory form for step with runtime/timeout/outputs - @entry(trigger): field decorator for entry definitions - @input: field decorator for pipeline inputs - @output: field decorator for pipeline outputs decoratePipeline(PipelineClass, project, id) creates a Pipeline construct from a decorated class, producing the same Definition Graph as the Construct and SDK APIs. Metadata is stored via context.metadata (TC39 per-class metadata object), retrieved from the class constructor via a Symbol property (Symbol.metadata is not yet widely implemented in Bun). 11 decorator tests (8 behavior + 3 public API). 102 tests across 4 packages. No any types. override readonly cause present. Specs: 04-authoring-decorators (§9.3–9.8, §12, §14, §15).
