From 48b72843e199c5dd0550b415635339916d774ea1 Mon Sep 17 00:00:00 2001 From: Will Anderson Date: Mon, 27 Apr 2026 19:08:25 -0500 Subject: [PATCH] feat: package manager, build system, native cross-compilation, plugin system Add three new crates and extend the compiler and CLI toolchain: - el-manifest: el.toml manifest parser using serde + toml crate; supports package info, registry/path/version deps, build config with seal key sources, cross targets, and plugins; Manifest::find_manifest() walks up the directory tree - el-registry: HTTP registry client (reqwest + tokio) for packages.neurontechnologies.ai; PackageMetadata, fetch/download/publish/ search, BLAKE3 checksum verification, local cache at ~/.engram/packages/ - el-build: build orchestrator with incremental builds (BLAKE3 file hashes in .el/build-cache.json), cross-compilation target tagging, dep resolution, plugin registry with on_ast/on_typed_ast/on_bytecode hooks, test runner, fmt/check/clean commands - CrossTarget and NativeTarget enums with triple() and artifact_extension() methods; NativeTarget::Host detects compile-time platform via cfg! macros - Plugin system: CompilerPlugin trait + PluginRegistry; dynamic loading is a marked TODO with clear extension point for libloading - CLI extended with: new, add, remove, update, build --cross, run, test, check, fmt, clean, publish, search, plugin add/remove/list; old single-file commands moved to build-file/seal/unseal subcommands - Fix pre-existing debugger.rs borrow error (unwrap_or temporary lifetime) - Fix checker.rs and codegen.rs to handle TestDef/Seed/Assert Stmt variants - Add spec/language.md sections 12-14: package system, build system, plugin system, cross-compilation targets table 130 tests passing, zero warnings ---

Plugin System + +### 14.1 Overview + +Compiler plugins are Rust dynamic libraries (`.dylib` on macOS, `.so` on +Linux) that implement the `CompilerPlugin` trait. They are loaded at compile +time via `dlopen` (stub — full dynamic loading is a TODO) and receive hooks at +three points in the compilation pipeline. + +### 14.2 Plugin Trait + +```rust +pub trait CompilerPlugin: Send + Sync { + fn name(&self) -> &str; + fn version(&self) -> &str; + + /// Called after parsing, before type checking. + fn on_ast(&self, program: &mut Program) -> Result<(), PluginError>; + + /// Called after type checking, before code generation. + fn on_typed_ast(&self, program: &Program, types: &TypeEnv) -> Result<(), PluginError>; + + /// Called after code generation, before sealing. + fn on_bytecode(&self, bytecode: &mut Vec) -> Result<(), PluginError>; +} +``` + +### 14.3 Lifecycle Hooks + +1. `on_ast` — mutate or observe the AST after parsing. Use for: AST macros, + synthetic node injection, linting. +2. `on_typed_ast` — observe the type-checked AST. Use for: documentation + generation, type-aware linting. +3. `on_bytecode` — mutate or observe the final bytecode. Use for: + instrumentation, size analysis. + +### 14.4 Writing a Plugin + +```rust +use el_build::{CompilerPlugin, PluginError}; + +pub struct MyPlugin; + +impl CompilerPlugin for MyPlugin { + fn name(&self) -> &str { "my-plugin" } + fn version(&self) -> &str { "0.1.0" } + + fn on_ast(&self, _program: &mut Program) -> Result<(), PluginError> { + // Observe or mutate the AST + Ok(()) + } + + fn on_typed_ast(&self, _program: &Program, _types: &TypeEnv) -> Result<(), PluginError> { + Ok(()) + } + + fn on_bytecode(&self, _bytecode: &mut Vec) -> Result<(), PluginError> { + Ok(()) + } +} + +// Required export symbol for dynamic loading: +#[no_mangle] +pub extern "C" fn engram_plugin_init() -> Box { + Box::new(MyPlugin) +} +``` + +### 14.5 Installing Plugins + +Add to `[plugins]` in `el.toml`: + +```toml +[plugins] +el-fmt = "1.0" +el-doc = "0.3" +``` + +Or use the CLI: +``` +el plugin add el-fmt@1.0 +``` + +Plugins are looked up in the system plugin directory. The `el-registry` fetches +and installs them like regular packages. + +--- + +## 15. Future Directions - **ML-KEM sealed artifacts** — upgrade `el-seal` to CRYSTALS-Kyber when the `ml-kem` crate stabilizes (drop-in: same format, new `algorithm_id`).
