From 2a1285c6145050344f80bf3d0be7f82bf72261b9 Mon Sep 17 00:00:00 2001 From: skobeltsyn Date: Sat, 30 May 2026 19:30:24 +0300 Subject: [PATCH] refactor(#2801): primary `(String) -> Any?` overload on LiveShow.from + LiveRunner.serve MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds a primary lambda-taking `from` / `serve` overload alongside the six existing typed overloads. Future operator types (Swarm, Stage, Branch-of-Branch, …) call the primary overload directly — no edit to LiveShow / LiveRunner required: ```kotlin LiveShow.from(myAgent::invokeSuspend) { theme = LiveShowTheme.NONE } LiveRunner.serve(myPipeline::invokeSuspend, args) ``` Source-compat preserved — the typed `from(Agent, ...)` / `from(Pipeline, ...)` / etc overloads all stay and continue to delegate to the same `buildShow` / `run` helpers. Deferred to follow-up (out of scope for this maintainability pass — flagged honestly): - `Pipeline.then` 17-overload unification + `StreamableExec` primitive for consistent emitter threading. Many of the 17 overloads predate streaming, and #1872's `PipelineSessionExtension` documents the gap; resolving it cleanly needs a streaming-aware `then` primitive and a deprecation cycle for non-streaming overloads. Larger than a maintainability slot. Full ./gradlew test green; 254+ TEST-*.xml files, zero failures/errors.
