From ddd7856f9b28bdf9d008badefc801ad1bba7f523 Mon Sep 17 00:00:00 2001 From: Ed Zynda Date: Fri, 27 Jun 2025 17:41:18 +0300 Subject: [PATCH] Refactor: Extract shared code between normal and script modes (#94) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit addresses issue #92 by extracting duplicated code between normal mode (cmd/root.go) and script mode (cmd/script.go) into reusable factory functions and utilities. ## Changes Made ### New Factory Files - **internal/agent/factory.go**: Agent creation factory with spinner support - `CreateAgent()` function with configurable options - `ParseModelName()` utility for model string parsing - Spinner function injection to avoid import cycles - **internal/ui/factory.go**: CLI setup factory with standard configuration - `SetupCLI()` function for consistent CLI initialization - Usage tracking setup for supported providers - Model info and tool count display - **internal/config/merger.go**: Config loading and merging utilities - `LoadAndValidateConfig()` for standard config loading - `MergeConfigs()` for script frontmatter merging ### Updated Command Files - **cmd/root.go**: Refactored to use new factories - Replaced ~50 lines of agent creation logic - Replaced ~30 lines of CLI setup logic - Replaced ~20 lines of config loading logic - Added agentUIAdapter to handle interface compatibility - **cmd/script.go**: Refactored to use new factories - Same factory usage as normal mode for consistency - Maintained script-specific behavior (no spinners) - Improved config merging with frontmatter ## Benefits - **Reduced code duplication**: ~33 lines of duplicated code eliminated - **Single source of truth**: Agent creation and CLI setup logic centralized - **Consistent behavior**: Both modes now use identical underlying logic - **Easier maintenance**: Changes apply to both modes automatically - **Better testability**: Factory functions can be unit tested independently - **Cleaner command files**: Focus on mode-specific logic only ## Testing - All existing tests pass - Build verification successful - Both normal and script modes tested for basic functionality - Code formatting and linting checks passed 🤖 Generated with [opencode](https://opencode.ai) Co-authored-by: opencode --- cmd/root.go | 285
