From 2d1b26d512475c9dd435b8e109737aebdbe90b90 Mon Sep 17 00:00:00 2001 From: Jonas Templestein <242550+jonastemplestein@users.noreply.github.com> Date: Thu, 4 Dec 2025 22:19:44 +0000 Subject: [PATCH 01/14] Add codemode infrastructure for code block execution MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements the core services needed for codemode functionality: - codemode.model.ts: Event schemas and block parsing - codemode.repository.ts: Stores generated code in timestamped directories - typechecker.service.ts: TypeScript compiler API wrapper for validation - code-executor.service.ts: Bun subprocess execution with streaming output - codemode.service.ts: Orchestrates parse/store/typecheck/execute workflow Also adds error types, wires layers into main.ts, and updates vitest config to include colocated tests in src/. šŸ¤– Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- src/cli/main.ts | 12 ++ src/code-executor.service.ts | 143 ++++++++++++++++++++ src/codemode.model.test.ts | 83 ++++++++++++ src/codemode.model.ts | 118 +++++++++++++++++ src/codemode.repository.ts | 244 +++++++++++++++++++++++++++++++++++ src/codemode.service.test.ts | 46 +++++++ src/codemode.service.ts | 184 ++++++++++++++++++++++++++ src/errors.ts | 39 ++++++ src/typechecker.service.ts | 99 ++++++++++++++ vitest.config.ts | 2 +- 10 files changed, 969 insertions(+), 1 deletion(-) create mode 100644 src/code-executor.service.ts create mode 100644 src/codemode.model.test.ts create mode 100644 src/codemode.model.ts create mode 100644 src/codemode.repository.ts create mode 100644 src/codemode.service.test.ts create mode 100644 src/codemode.service.ts create mode 100644 src/typechecker.service.ts diff --git a/src/cli/main.ts b/src/cli/main.ts index 06a43a6..98da269 100644 --- a/src/cli/main.ts +++ b/src/cli/main.ts @@ -7,6 +7,9 @@ import { OpenAiClient, OpenAiLanguageModel } from "@effect/ai-openai" import { FetchHttpClient } from "@effect/platform" import { BunContext, BunRuntime } from "@effect/platform-bun" import { Cause, Effect, Layer } from "effect" +import { CodeExecutor } from "../code-executor.service.ts" +import { CodemodeRepository } from "../codemode.repository.ts" +import { CodemodeService } from "../codemode.service.ts" import { AppConfig, extractConfigPath, @@ -21,6 +24,7 @@ import { CurrentLlmConfig, getApiKey, type LlmConfig, resolveLlmConfig } from ". import { createLoggingLayer } from "../logging.ts" import { OpenAiChatClient, OpenAiChatLanguageModel } from "../openai-chat-completions-client.ts" import { createTracingLayer } from "../tracing.ts" +import { TypecheckService } from "../typechecker.service.ts" import { cli, GenAISpanTransformerLayer } from "./commands.ts" const makeLanguageModelLayer = (llmConfig: LlmConfig) => { @@ -97,8 +101,16 @@ const makeMainLayer = (args: ReadonlyArray) => const languageModelLayer = makeLanguageModelLayer(llmConfig) const tracingLayer = createTracingLayer("mini-agent") + // Build codemode layer stack + const codemodeLayer = CodemodeService.layer.pipe( + Layer.provide(CodemodeRepository.layer), + Layer.provide(TypecheckService.layer), + Layer.provide(CodeExecutor.layer) + ) + return ContextService.layer.pipe( Layer.provideMerge(ContextRepository.layer), + Layer.provideMerge(codemodeLayer), Layer.provideMerge(languageModelLayer), Layer.provideMerge(llmConfigLayer), Layer.provideMerge(tracingLayer), diff --git a/src/code-executor.service.ts b/src/code-executor.service.ts new file mode 100644 index 0000000..0410ba6 --- /dev/null +++ b/src/code-executor.service.ts @@ -0,0 +1,143 @@ +/** + * Code Executor Service + * + * Executes generated TypeScript code via bun subprocess. + * Streams stdout/stderr as events for real-time feedback. + */ +import { Command, CommandExecutor } from "@effect/platform" +import type { Error as PlatformError } from "@effect/platform" +import type { Scope } from "effect" +import { Context, Effect, Layer, pipe, Stream } from "effect" +import { ExecutionCompleteEvent, ExecutionOutputEvent, ExecutionStartEvent, type ResponseId } from "./codemode.model.ts" + +/** Union of execution events for streaming */ +export type ExecutionEvent = ExecutionStartEvent | ExecutionOutputEvent | ExecutionCompleteEvent + +/** Interface for code executor */ +interface CodeExecutorInterface { + /** + * Execute a TypeScript file via bun subprocess. + * Streams execution events: start, output chunks, complete. + */ + readonly execute: ( + indexPath: string, + responseId: ResponseId + ) => Stream.Stream +} + +export class CodeExecutor extends Context.Tag("@app/CodeExecutor")< + CodeExecutor, + CodeExecutorInterface +>() { + static readonly layer = Layer.effect( + CodeExecutor, + Effect.gen(function*() { + const executor = yield* CommandExecutor.CommandExecutor + + const execute = ( + indexPath: string, + responseId: ResponseId + ): Stream.Stream => + pipe( + Stream.make(new ExecutionStartEvent({ responseId })), + Stream.concat( + Stream.unwrap( + Effect.gen(function*() { + // Create runner code that imports and executes the generated module + const runnerCode = ` +const indexPath = ${JSON.stringify(indexPath)};
