From 52c8ce1f7b7f6edd3e2ebdf891816fdf4e4e723a Mon Sep 17 00:00:00 2001 From: Moe Charm Date: Tue, 19 Aug 2025 05:16:40 +0900 Subject: [PATCH] feat: Implement nyash.toml v2 plugin system with PluginLoaderV2 - Add plugin_loader_v2.rs with nyash.toml v2 support - Create PluginBoxV2 as temporary wrapper for v2 plugins - Update runner.rs to use v2 loader instead of legacy BID registry - Update box_registry.rs to work with v2 plugin system - Support single FFI entry point (nyash_plugin_invoke) + optional init - Integrate with existing BoxFactoryRegistry for seamless Box creation - All compilation errors resolved, ready for testing --- src/runner.rs | 40 ++++-- src/runtime/box_registry.rs | 14 +- src/runtime/mod.rs | 2 + src/runtime/plugin_loader_v2.rs | 238 ++++++++++++++++++++++++++++++++ 4 files changed, 278 insertions(+), 16 deletions(-) create mode 100644 src/runtime/plugin_loader_v2.rs diff --git a/src/runner.rs b/src/runner.rs index 9ba22470..920fb5ac 100644 --- a/src/runner.rs +++ b/src/runner.rs @@ -20,8 +20,8 @@ use crate::{ use crate::backend::{llvm_compile_and_execute}; use std::{fs, process}; -// BID prototype imports -use crate::bid::{PluginRegistry, PluginBoxInstance}; +// v2 plugin system imports +use crate::runtime::init_global_loader_v2; /// Main execution coordinator pub struct NyashRunner { @@ -58,18 +58,34 @@ impl NyashRunner { fn init_bid_plugins(&self) { // Best-effort init; do not fail the program if missing - eprintln!("🔍 DEBUG: init_bid_plugins called"); - if let Ok(()) = crate::bid::registry::init_global_from_config("nyash.toml") { - let reg = crate::bid::registry::global().unwrap(); - // If FileBox plugin is present, try a birth/fini cycle as a smoke test - if let Some(plugin) = reg.get_by_name("FileBox") { - if let Ok(inst) = PluginBoxInstance::birth(plugin) { - println!("🔌 BID plugin loaded: FileBox (instance_id={})", inst.instance_id); - // Drop will call fini - return; + eprintln!("🔍 DEBUG: Initializing v2 plugin system"); + + // Try to load nyash.toml configuration + if let Ok(()) = init_global_loader_v2("nyash.toml") { + println!("🔌 v2 plugin system initialized from nyash.toml"); + + // Apply plugin configuration to the box registry + use crate::runtime::{get_global_registry, get_global_loader_v2}; + + let loader = get_global_loader_v2(); + let loader = loader.read().unwrap(); + + if let Some(config) = &loader.config { + // Register plugin providers in the box registry + let registry = get_global_registry(); + + for (lib_name, lib_def) in &config.libraries { + for box_name in &lib_def.boxes { + eprintln!(" 📦 Registering plugin provider for {}", box_name); + // Note: plugin_name is lib_name in v2 system + registry.apply_plugin_config(&crate::runtime::PluginConfig { + plugins: [(box_name.clone(), lib_name.clone())].into(), + }); + } } } - println!("🔌 BID registry initialized"); + } else { + eprintln!("⚠️ Failed to load nyash.toml - plugins disabled"); } } diff --git a/src/runtime/box_registry.rs b/src/runtime/box_registry.rs index ed8e083b..e4973c48 100644 --- a/src/runtime/box_registry.rs +++ b/src/runtime/box_registry.rs @@ -75,11 +75,17 @@ impl BoxFactoryRegistry { } } - /// プラグインBoxを生成（v2への移行中の一時的スタブ） + /// プラグインBoxを生成（v2実装） fn create_plugin_box(&self, plugin_name: &str, box_name: &str, args: &[Box]) -> Result, String> { - // TODO: v2プラグインシステムへの実装 - // 現在は一時的にエラーを返す - Err(format!("Plugin system v2 migration in progress.
