# Nyash Kernel
|
||
|
||
**Minimal runtime kernel for Nyash language - Plugin-First Architecture**
|
||
|
||
Generated: 2025-09-24
|
||
Architecture: Phase 2.4 NyRT→NyKernel Revolution Complete
|
||
|
||
## Overview
|
||
|
||
The Nyash Kernel (`nyash_kernel`) is the minimal runtime core that replaced the legacy NyRT system. This represents a **42% reduction** in runtime complexity by moving from VM-dependent architecture to a unified Plugin-First system.
|
||
|
||
## Architecture Revolution
|
||
|
||
### ✅ **From NyRT to NyKernel** (Phase 2.4 Complete)
|
||
|
||
**Before (Legacy NyRT)**:
|
||
- Mixed VM/Plugin dependencies
|
||
- `with_legacy_vm_args` scattered throughout codebase
|
||
- 58% essential + 42% deletable functions
|
||
- Complex shim layer for LLVM integration
|
||
|
||
**After (NyKernel)**:
|
||
- Pure Plugin-First architecture
|
||
- Zero legacy VM dependencies
|
||
- Only essential kernel functions remain
|
||
- Clean C ABI for LLVM integration
|
||
|
||
### 🏗️ **Core Components**
|
||
|
||
#### Essential Kernel Functions (58% - Kept)
|
||
- **GC Management**: Safepoints, write barriers, memory management
|
||
- **Handle Registry**: Object handle management for AOT/JIT
|
||
- **Plugin Host**: Unified plugin loading and method resolution
|
||
- **Process Entry**: Main entry point and runtime initialization
|
||
|
||
#### Removed Shim Functions (42% - Deleted)
|
||
- `with_legacy_vm_args` - 11 locations completely removed
|
||
- Legacy VM argument processing
|
||
- String/Box operation shims
|
||
- VM-specific encoding functions
|
||
|
||
## Build Output
|
||
|
||
```
|
||
Target: libnyash_kernel.a (static library)
|
||
Status: Clean build (0 errors, 0 warnings)
|
||
Integration: LLVM + VM unified
|
||
```
|
||
|
||
## Implementation Details
|
||
|
||
### Deleted Legacy Functions
|
||
|
||
| File | Locations | Status |
|
||
|------|-----------|---------|
|
||
| `encode.rs` | 1 | ✅ Removed |
|
||
| `birth.rs` | 1 | ✅ Removed |
|
||
| `future.rs` | 2 | ✅ Removed |
|
||
| `invoke.rs` | 6 | ✅ Removed |
|
||
| `invoke_core.rs` | 1 | ✅ Removed |
|
||
| **Total** | **11** | **✅ Complete** |
|
||
|
||
### Plugin-First Integration
|
||
|
||
All Box operations now route through the unified plugin system:
|
||
|
||
```rust
|
||
// Before: VM-dependent
|
||
with_legacy_vm_args(|args| { ... })
|
||
|
||
// After: Plugin-First
|
||
let host = get_global_plugin_host().read()?;
|
||
host.create_box(type_name, &args)?
|
||
```
|
||
|
||
## Usage
|
||
|
||
### For LLVM Backend
|
||
```bash
|
||
# Build with LLVM integration
|
||
cargo build --release -p nyash_kernel
|
||
# Output: crates/nyash_kernel/target/release/libnyash_kernel.a
|
||
```
|
||
|
||
### For VM Backend
|
||
```bash
|
||
# Runtime integration (automatic)
|
||
./target/release/nyash program.nyash
|
||
```
|
||
|
||
## Design Philosophy
|
||
|
||
**"Everything is Plugin"** - The kernel provides only the essential infrastructure for plugin management, leaving all Box implementations to the plugin system.
|
||
|
||
### Core Principles
|
||
1. **Minimal Surface**: Only GC, handles, plugins, and process entry
|
||
2. **Plugin-First**: All Box operations through unified plugin host
|
||
3. **C ABI Clean**: Stable interface for LLVM/VM integration
|
||
4. **Zero Legacy**: Complete removal of VM-dependent code paths

|
||
- **LLVM Backend**: Static linking via libnyash_kernel.a
|
||
- **VM Backend**: Dynamic plugin loading
|
||
- **Build System**: tools/build_llvm.sh integration complete
