+
+ ## Why Hyperparameter?
+
+ ### 🚀 Unmatched Performance (vs Hydra)
+
+ Hyperparameter is built on a high-performance Rust backend, making it significantly faster than pure Python alternatives like Hydra, especially in inner-loop parameter access.
+
+ | Method | Time (1M iters) | Speedup (vs Hydra) |
+ | :--- | :--- | :--- |
+ | **HP: Injected (Native Speed)** | **0.0184s** | **856.73x** 🚀 |
+ | **HP: Dynamic (Optimized)** | **2.4255s** | **6.50x** ⚡️ |
+ | **Hydra (Baseline)** | 15.7638s | 1.00x |
+
+ > Benchmark scenario: Accessing a nested parameter `model.layers.0.size` 1,000,000 times in a loop.
+ > See `benchmark/` folder for reproduction scripts.
+
+ ### ✨ Zero-Dependency Schema Validation
+
+ Hyperparameter supports structural validation using standard Python type hints without introducing heavy dependencies (like Pydantic or OmegaConf).
+
+ ```python
+ from dataclasses import dataclass
+ import hyperparameter as hp
+
+ @dataclass
+ class AppConfig:
+ host: str
+ port: int
+ debug: bool = False
+
+ # Validates types and converts automatically: "8080" -> 8080 (int)
+ cfg = hp.config("config.toml", schema=AppConfig)
+ ```
+
+ ## Key Features
### For Python Users
- **Pythonic Syntax:** Define hyperparameters using keyword argument syntax;
-- **Intuitive Scoping:** Control parameter scope through `with` statement;
-
-- **Configuration File:** Easy to load parameters from config files;
-
-### For Rust and C++ Users
+ - **Intuitive Scoping:** Control parameter scope through `with` statement;
+
+ - **Configuration File:** Easy to load parameters from config files (JSON/TOML/YAML) with composition and interpolation support;
+
+ - **Zero-Overhead Validation:** Optional schema validation using standard Python type hints;
+
+ ### For Rust and C++ Users
- **High-Performance Backend:** Hyperparameter is implemented in Rust, providing a robust and high-performance backend for hyperparameter management. Access hyperparameters in Rust and C++ with minimal overhead, making it ideal for ML and system developers who prioritize performance.

+
+## Component Details
+
+### 1. Python API Layer (`hyperparameter/api.py`)
+
+This is what users interact with directly.
+
+**Key Classes:**
+
+- **`scope`**: A context manager that creates a new parameter hp.scope.
+ ```python
+ with hp.scope(foo=1, bar=2) as ps:
+ # ps.foo() returns 1
+ # Nested scopes inherit from parent
+ ```
+
+- **`_ParamAccessor`**: Handles the `hp.scope.x.y.z | default` syntax.
+ ```python
+ # This chain: hp.scope.model.layers.size | 10
+ # Creates: _ParamAccessor(root, "model.layers.size")
+ # The `|` operator calls get_or_else(10)
+ ```
+
+- **`param` decorator**: Inspects function signature and injects values.
+ ```python
+ @hp.param("model")
+ def foo(hidden_size=256): # Looks up "model.hidden_size"
+ pass
+ ```
+
+### 2. Storage Layer (`hyperparameter/storage.py`)
+
+The storage layer abstracts the underlying key-value store.
+
+**Key Features:**
+
+- **Thread-Local Storage (TLS)**: Each thread has its own parameter stack.
+- **Scoped Updates**: Changes are local to the current scope and roll back on exit.
+- **Backend Selection**: Automatically uses Rust backend if available.
+
+```python
+class TLSKVStorage:
+ """Thread-local key-value storage with scope stack."""
+
+ def enter(self):
+ """Push a new scope onto the stack."""
+
+ def exit(self):
+ """Pop the current scope, rolling back changes."""
+
+ def get(self, key: str) -> Any:
+ """Look up key in current scope, then parent scopes."""
+
+ def put(self, key: str, value: Any):
+ """Set key in current scope only."""
+```
+
+### 3. Rust Backend (`src/core/`, `src/py/`)
+
+The Rust backend provides high-performance parameter access.
+
+**Why Rust?**
+
+1. **Compile-time key hashing**: Keys like `"model.layers.size"` are hashed at compile time using `xxhash`, eliminating runtime string hashing overhead.
+
+2. **Lock-free reads**: Thread-local storage means no mutex contention on reads.
+
+3. **Zero-copy string handling**: Rust's string handling avoids Python's string interning overhead.
+
+**Key Rust Components:**
+
+```rust
+// src/core/src/storage.rs
+pub struct ThreadLocalStorage {
+ stack: Vec>, // Scope stack
+}
+
+// src/core/src/xxh.rs
+pub const fn xxhash(s: &str) -> u64 {
+ // Compile-time xxhash64
+}
+
+// src/core/src/api.rs
+pub fn get_param(key_hash: u64, default: T) -> T {
+ // Fast lookup by pre-computed hash
+}
+```
+
+**Python Binding (`src/py/`):**
+
+Uses PyO3 to expose Rust functions to Python:
+
+```rust
+#[pyfunction]
+fn get_entry(key_hash: u64) -> PyResult {
+ // Called from Python with pre-computed hash
+}
+```
+
+### 4. Config Loader (`hyperparameter/loader.py`)
+
+The loader handles configuration file parsing and processing.
+
+**Pipeline:**
+
+```
+File(s) → Parse → Merge → Interpolate → Validate → Dict/Object
+```
+
+1. **Parse**: Support for TOML, JSON, YAML
+2. **Merge**: Deep merge multiple configs (later overrides earlier)
+3. **Interpolate**: Resolve `${variable}` references
+4. **Validate**: Optional schema validation against class type hints
+
+```python
+def load(path, schema=None):
+ config = _load_and_merge(path)
+ config = _resolve_interpolations(config)
+ if schema:
+ return validate(config, schema)
+ return config
+```
+
+## Data Flow Example
+
+Let's trace what happens when you run:
+
+```python
+import hyperparameter as hp
+
+@hp.param("model")
+def train(lr=0.001):
+ print(lr)
+
+with hp.scope(**{"model.lr": 0.01}):
+ train()
+```
+
+**Step-by-step:**
+
+1. **`scope(**{"model.lr": 0.01})`**:
+ - Creates new `TLSKVStorage` scope
+ - Computes hash: `xxhash("model.lr")` → `0x1234...`
+ - Stores: `{0x1234...: 0.01}` in current thread's scope stack
+
+2. **`train()` called**:
+ - `@hp.param` wrapper runs
+ - For each kwarg with default (`lr=0.001`):
+ - Computes hash: `xxhash("model.lr")`
+ - Calls `storage.get_entry(0x1234...)`
+ - Rust backend returns `0.01`
+ - Calls `train(lr=0.01)`
+
+3. **Scope exit**:
+ - `hp.scope.__exit__()` called
+ - Pops scope from stack
+ - `model.lr` no longer accessible
+
+## Performance Characteristics
+
+### Why Hyperparameter is Fast
+
+| Operation | Hydra/OmegaConf | Hyperparameter |
+| :--- | :--- | :--- |
+| Key lookup | String hash at runtime | Pre-computed xxhash |
+| Type checking | On every access | Optional, at load time |
+| Thread safety | Global lock | Thread-local (no lock) |
+| Memory | Python dicts + wrappers | Rust HashMap |
+
+### When to Use Which Access Pattern
+
+| Pattern | Speed | Use Case |
+| :--- | :--- | :--- |
+| `@hp.param` injection | 🚀🚀🚀 Fastest | Hot loops, performance-critical |
+| `with hp.scope() as ps: ps.x` | 🚀🚀 Fast | Most code |
+| `hp.scope.x` (global) | 🚀 Moderate | Convenience, one-off access |
+
+## Thread Safety Model
+
+```
+Thread 1 Thread 2
+──────── ────────
+hp.scope(a=1)
+│ scope(a=2)
+│ a = 1 │ a = 2
+│ │
+└── exit └── exit
+ a = undefined a = undefined
+```
+
+Each thread has **independent scope stacks**. Changes in one thread never affect another.
+
+**`frozen()` for cross-thread defaults:**
+
+```python
+with hp.scope(a=1):
+ hp.scope.frozen() # Snapshot current scope as global default
+
+# New threads will see a=1 as their initial state
+```
+
+## Extending Hyperparameter
+
+### Custom Storage Backend
+
+```python
+from hyperparameter.storage import TLSKVStorage
+
+class RedisBackedStorage(TLSKVStorage):
+ """Example: Redis-backed storage for distributed systems."""
+
+ def get(self, key):
+ # Try local first
+ value = super().get(key)
+ if value is None:
+ # Fall back to Redis
+ value = self.redis.get(key)
+ return value
+```
+
+### Custom Type Coercion
+
+```python
+from hyperparameter.loader import _coerce_type
+
+def _coerce_type(value, target_type):
+ # Add custom type handling
+ if target_type is MyCustomType:
+ return MyCustomType.from_string(value)
+ # ... existing logic

+```
+
+## 组件详解
+
+### 1. Python API 层 (`hyperparameter/api.py`)
+
+这是用户直接交互的部分。
+
+**核心类:**
+
+- **`scope`**: 创建新参数作用域的上下文管理器。
+ ```python
+ with hp.scope(foo=1, bar=2) as ps:
+ # ps.foo() 返回 1
+ # 嵌套作用域从父作用域继承
+ ```
+
+- **`_ParamAccessor`**: 处理 `hp.scope.x.y.z | default` 语法。
+ ```python
+ # 这个链式调用: hp.scope.model.layers.size | 10
+ # 创建: _ParamAccessor(root, "model.layers.size")
+ # `|` 运算符调用 get_or_else(10)
+ ```
+
+- **`param` 装饰器**: 检查函数签名并注入值。
+ ```python
+ @hp.param("model")
+ def foo(hidden_size=256): # 查找 "model.hidden_size"
+ pass
+ ```
+
+### 2. 存储层 (`hyperparameter/storage.py`)
+
+存储层抽象了底层的键值存储。
+
+**核心特性:**
+
+- **线程本地存储 (TLS)**: 每个线程有自己的参数栈。
+- **作用域更新**: 更改仅限当前作用域，退出时回滚。
+- **后端选择**: 如果可用则自动使用 Rust 后端。
+
+```python
+class TLSKVStorage:
+ """带作用域栈的线程本地键值存储"""
+
+ def enter(self):
+ """将新作用域压入栈"""
+
+ def exit(self):
+ """弹出当前作用域，回滚更改"""
+
+ def get(self, key: str) -> Any:
+ """在当前作用域查找键，然后查找父作用域"""
+
+ def put(self, key: str, value: Any):
+ """仅在当前作用域设置键"""
+```
+
+### 3. Rust 后端 (`src/core/`, `src/py/`)
+
+Rust 后端提供高性能的参数访问。
+
+**为什么用 Rust?**
+
+1. **编译时键哈希**: 像 `"model.layers.size"` 这样的键在编译时使用 `xxhash` 哈希，消除了运行时字符串哈希开销。
+
+2. **无锁读取**: 线程本地存储意味着读取时没有互斥锁竞争。
+
+3. **零拷贝字符串处理**: Rust 的字符串处理避免了 Python 字符串驻留的开销。
+
+**核心 Rust 组件:**
+
+```rust
+// src/core/src/storage.rs
+pub struct ThreadLocalStorage {
+ stack: Vec>, // 作用域栈
+}
+
+// src/core/src/xxh.rs
+pub const fn xxhash(s: &str) -> u64 {
+ // 编译时 xxhash64
+}
+
+// src/core/src/api.rs
+pub fn get_param(key_hash: u64, default: T) -> T {
+ // 通过预计算哈希快速查找
+}
+```
+
+**Python 绑定 (`src/py/`):**
+
+使用 PyO3 将 Rust 函数暴露给 Python:
+
+```rust
+#[pyfunction]
+fn get_entry(key_hash: u64) -> PyResult {
+ // 从 Python 调用，使用预计算的哈希
+}
+```
+
+### 4. 配置加载器 (`hyperparameter/loader.py`)
+
+加载器处理配置文件解析和处理。
+
+**处理流水线:**
+
+```
+文件 → 解析 → 合并 → 插值 → 校验 → 字典/对象
+```
+
+1. **解析**: 支持 TOML、JSON、YAML
+2. **合并**: 深度合并多个配置（后者覆盖前者）
+3. **插值**: 解析 `${variable}` 引用
+4. **校验**: 可选的基于类类型提示的 Schema 校验
+
+```python
+def load(path, schema=None):
+ config = _load_and_merge(path)
+ config = _resolve_interpolations(config)
+ if schema:
+ return validate(config, schema)
+ return config
+```
+
+## 数据流示例
+
+让我们追踪运行以下代码时发生了什么:
+
+```python
+import hyperparameter as hp
+
+@hp.param("model")
+def train(lr=0.001):
+ print(lr)
+
+with hp.scope(**{"model.lr": 0.01}):
+ train()
+```
+
+**逐步分析:**
+
+1. **`scope(**{"model.lr": 0.01})`**:
+ - 创建新的 `TLSKVStorage` 作用域
+ - 计算哈希: `xxhash("model.lr")` → `0x1234...`
+ - 存储: `{0x1234...: 0.01}` 到当前线程的作用域栈
+
+2. **`train()` 被调用**:
+ - `@hp.param` 包装器运行
+ - 对每个有默认值的参数 (`lr=0.001`):
+ - 计算哈希: `xxhash("model.lr")`
+ - 调用 `storage.get_entry(0x1234...)`
+ - Rust 后端返回 `0.01`
+ - 调用 `train(lr=0.01)`
+
+3. **作用域退出**:
+ - `hp.scope.__exit__()` 被调用
+ - 从栈中弹出作用域
+ - `model.lr` 不再可访问
+
+## 性能特征
+
+### 为什么 Hyperparameter 快
+
+| 操作 | Hydra/OmegaConf | Hyperparameter |
+| :--- | :--- | :--- |
+| 键查找 | 运行时字符串哈希 | 预计算 xxhash |
+| 类型检查 | 每次访问都检查 | 可选，加载时检查 |
+| 线程安全 | 全局锁 | 线程本地（无锁） |
+| 内存 | Python 字典 + 包装器 | Rust HashMap |
+
+### 何时使用哪种访问模式
+
+| 模式 | 速度 | 使用场景 |
+| :--- | :--- | :--- |
+| `@hp.param` 注入 | 🚀🚀🚀 最快 | 热循环，性能关键 |
+| `with hp.scope() as ps: ps.x` | 🚀🚀 快 | 大多数代码 |
+| `hp.scope.x` (全局) | 🚀 中等 | 便捷访问，一次性访问 |
+
+## 线程安全模型
+
+```
+线程 1 线程 2
+────── ──────
+hp.scope(a=1)
+│ scope(a=2)
+│ a = 1 │ a = 2
+│ │
+└── 退出 └── 退出
+ a = 未定义 a = 未定义
+```
+
+每个线程有**独立的作用域栈**。一个线程的更改永远不会影响另一个线程。
+
+**`frozen()` 用于跨线程默认值:**
+
+```python
+with hp.scope(a=1):
+ hp.scope.frozen() # 将当前作用域快照为全局默认值
+
+# 新线程将以 a=1 作为初始状态
+```
+
+## 扩展 Hyperparameter
+
+### 自定义存储后端
+
+```python
+from hyperparameter.storage import TLSKVStorage
+
+class RedisBackedStorage(TLSKVStorage):
+ """示例: 用于分布式系统的 Redis 后端存储"""
+
+ def get(self, key):
+ # 先尝试本地
+ value = super().get(key)
+ if value is None:
+ # 回退到 Redis
+ value = self.redis.get(key)
+ return value
+```
+
+### 自定义类型转换
+
+```python
+from hyperparameter.loader import _coerce_type
+
+def _coerce_type(value, target_type):
+ # 添加自定义类型处理
+ if target_type is MyCustomType:
+ return MyCustomType.from_string(value)
+ # ... 现有逻辑
+```

+
+## Multi-Environment Configuration
+
+### Problem
+You need different configurations for development, staging, and production environments.
+
+### Solution
+
+**Directory Structure:**
+```
+config/
+├── base.toml # Shared defaults
+├── dev.toml # Development overrides
+├── staging.toml # Staging overrides
+└── prod.toml # Production overrides
+```
+
+**base.toml:**
+```toml
+[database]
+host = "localhost"
+port = 5432
+pool_size = 5
+
+[logging]
+level = "INFO"
+format = "%(asctime)s - %(message)s"
+
+[model]
+batch_size = 32
+learning_rate = 0.001
+```
+
+**dev.toml:**
+```toml
+[database]
+host = "localhost"
+
+[logging]
+level = "DEBUG"
+
+[model]
+batch_size = 8 # Smaller for faster iteration
+```
+
+**prod.toml:**
+```toml
+[database]
+host = "prod-db.example.com"
+pool_size = 20
+
+[logging]
+level = "WARNING"
+
+[model]
+batch_size = 256
+```
+
+**main.py:**
+```python
+import os
+import hyperparameter as hp
+
+def load_config():
+ env = os.environ.get("ENV", "dev")
+ return hp.config([
+ "config/base.toml",
+ f"config/{env}.toml"
+ ])
+
+@hp.param("model")
+def train(batch_size=32, learning_rate=0.001):
+ print(f"Training with batch_size={batch_size}, lr={learning_rate}")
+
+if __name__ == "__main__":
+ cfg = load_config()
+ with hp.scope(**cfg):
+ train()
+```
+
+**Usage:**
+```bash
+ENV=dev python main.py # batch_size=8
+ENV=prod python main.py # batch_size=256
+```
+
+---
+
+## Configuration Inheritance
+
+### Problem
+You have multiple model variants that share common settings but differ in specific parameters.
+
+### Solution
+
+**config/models/base_transformer.toml:**
+```toml
+[model]
+type = "transformer"
+num_layers = 6
+hidden_size = 512
+num_heads = 8
+dropout = 0.1
+activation = "gelu"
+```
+
+**config/models/bert_base.toml:**
+```toml
+[model]
+num_layers = 12
+hidden_size = 768
+num_heads = 12
+vocab_size = 30522
+```
+
+**config/models/bert_large.toml:**
+```toml
+[model]
+num_layers = 24
+hidden_size = 1024
+num_heads = 16
+vocab_size = 30522
+```
+
+**main.py:**
+```python
+import hyperparameter as hp
+
+def load_model_config(model_name: str):
+ """Load model config with inheritance."""
+ base_config = "config/models/base_transformer.toml"
+ model_config = f"config/models/{model_name}.toml"
+ return hp.config([base_config, model_config])
+
+# Usage
+cfg = load_model_config("bert_large")
+# Result: num_layers=24, hidden_size=1024, dropout=0.1 (inherited)
+```
+
+---
+
+## Secrets Management
+
+### Problem
+You need to manage sensitive values (API keys, passwords) without committing them to git.
+
+### Solution
+
+**config/app.toml:**
+```toml
+[api]
+base_url = "https://api.example.com"
+timeout = 30
+
+[database]
+host = "${DATABASE_HOST}" # From environment variable
+password = "${DATABASE_PASS}"
+```
+
+**config/secrets.local.toml** (gitignored):
+```toml
+[api]
+key = "sk-your-actual-api-key"
+
+[database]
+password = "actual-password"
+```
+
+**.gitignore:**
+```
+config/secrets.local.toml
+```
+
+**main.py:**
+```python
+import os
+from pathlib import Path
+import hyperparameter as hp
+
+def load_config_with_secrets():
+ configs = ["config/app.toml"]
+
+ # Load local secrets if exists
+ secrets_file = Path("config/secrets.local.toml")
+ if secrets_file.exists():
+ configs.append(str(secrets_file))
+
+ cfg = hp.config(configs)
+ return cfg
+
+cfg = load_config_with_secrets()
+```
+
+---
+
+## Feature Flags
+
+### Problem
+You want to enable/disable features without code changes.
+
+### Solution
+
+**config/features.toml:**
+```toml
+[features]
+new_ui = false
+experimental_model = false
+debug_mode = true
+rate_limiting = true
+
+[features.ab_test]
+enabled = true
+variant = "control" # "control" or "treatment"
+```
+
+**main.py:**
+```python
+import hyperparameter as hp
+
+cfg = hp.config("config/features.toml")
+
+with hp.scope(**cfg):
+ # Check feature flags anywhere in code
+ if hp.scope.features.new_ui | False:
+ render_new_ui()
+ else:
+ render_old_ui()
+
+ if hp.scope.features.experimental_model | False:
+ model = ExperimentalModel()
+ else:
+ model = StableModel()
+```
+
+**Toggle via CLI:**
+```bash
+python main.py -D features.new_ui=true
+```
+
+---
+
+## A/B Testing Configuration
+
+### Problem
+You need to run experiments with different parameter configurations.
+
+### Solution
+
+```python
+import hyperparameter as hp
+import random
+
+@hp.param("experiment")
+def run_experiment(
+ model_type="baseline",
+ learning_rate=0.001,
+ batch_size=32
+):
+ print(f"Running: {model_type}, lr={learning_rate}, bs={batch_size}")
+ # ... training code ...
+
+def get_experiment_config(user_id: str):
+ """Deterministic assignment based on user_id."""
+ bucket = hash(user_id) % 100
+
+ if bucket < 50:
+ return {"experiment.model_type": "baseline"}
+ else:
+ return {"experiment.model_type": "new_model", "experiment.learning_rate": 0.0005}
+
+# Usage
+user_config = get_experiment_config("user_123")
+with hp.scope(**user_config):
+ run_experiment()
+```
+
+---
+
+## Multi-Stage Training (RL/ML)
+
+### Problem
+You have a training pipeline with multiple stages, each needing different configurations.
+
+### Solution
+
+```python
+import hyperparameter as hp
+
+@hp.param("train.pretrain")
+def pretrain(lr=0.001, epochs=10, warmup=True):
+ print(f"Pretraining: lr={lr}, epochs={epochs}, warmup={warmup}")
+
+@hp.param("train.finetune")
+def finetune(lr=0.0001, epochs=5, freeze_backbone=True):
+ print(f"Finetuning: lr={lr}, epochs={epochs}, freeze={freeze_backbone}")
+
+@hp.param("train.rl")
+def rl_train(lr=0.00001, episodes=1000, exploration=0.1):
+ print(f"RL Training: lr={lr}, episodes={episodes}, exploration={exploration}")
+
+def run_pipeline():
+ # Stage 1: Pretrain with high LR
+ with hp.scope(**{"train.pretrain.lr": 0.001, "train.pretrain.epochs": 20}):
+ pretrain()
+
+ # Stage 2: Finetune with low LR
+ with hp.scope(**{"train.finetune.lr": 0.00005}):
+ finetune()
+
+ # Stage 3: RL with decaying exploration
+ for stage, exploration in enumerate([0.5, 0.3, 0.1, 0.05]):
+ with hp.scope(**{"train.rl.exploration": exploration}):
+ print(f"--- RL Stage {stage + 1} ---")
+ rl_train()
+
+if __name__ == "__main__":
+ run_pipeline()
+```
+
+This showcases the **dynamic scoping** feature that Hydra cannot easily replicate.
+
+---
+
+## Tips and Best Practices
+
+### 1. Use Type Hints for Better IDE Support
+
+```python
+from dataclasses import dataclass
+import hyperparameter as hp
+
+@dataclass
+class ModelConfig:
+ hidden_size: int = 256
+ dropout: float = 0.1
+ activation: str = "relu"
+
+cfg: ModelConfig = hp.config("config.toml", schema=ModelConfig)
+# Now cfg.hidden_size has autocomplete!
+```
+
+### 2. Organize Configs by Concern
+
+```
+config/
+├── model/
+│ ├── bert.toml
+│ └── gpt.toml
+├── training/
+│ ├── default.toml
+│ └── distributed.toml
+├── data/
+│ └── preprocessing.toml
+└── base.toml
+```
+
+### 3. Use Interpolation for DRY Configs
+
+```toml
+[paths]
+root = "/project"
+data = "${paths.root}/data"
+models = "${paths.root}/models"
+logs = "${paths.root}/logs"
+```
+
+### 4. Document Your Config Files
+
+```toml
+# Model configuration for BERT variants
+# See: https://arxiv.org/abs/1810.04805
+
+[model]
+# Number of transformer layers (12 for base, 24 for large)
+num_layers = 12
+
+# Hidden dimension (768 for base, 1024 for large)
+hidden_size = 768
+```

+## 多环境配置
+
+### 问题
+你需要为开发、预发布和生产环境使用不同的配置。
+
+### 解决方案
+
+**目录结构:**
+```
+config/
+├── base.toml # 共享默认值
+├── dev.toml # 开发环境覆盖
+├── staging.toml # 预发布环境覆盖
+└── prod.toml # 生产环境覆盖
+```
+
+**base.toml:**
+```toml
+[database]
+host = "localhost"
+port = 5432
+pool_size = 5
+
+[logging]
+level = "INFO"
+format = "%(asctime)s - %(message)s"
+
+[model]
+batch_size = 32
+learning_rate = 0.001
+```
+
+**dev.toml:**
+```toml
+[database]
+host = "localhost"
+
+[logging]
+level = "DEBUG"
+
+[model]
+batch_size = 8 # 更小的 batch 加速迭代
+```
+
+**prod.toml:**
+```toml
+[database]
+host = "prod-db.example.com"
+pool_size = 20
+
+[logging]
+level = "WARNING"
+
+[model]
+batch_size = 256
+```
+

+
+def load_config():
+ env = os.environ.get("ENV", "dev")
+ return hp.config([
+ "config/base.toml",
+ f"config/{env}.toml"
+ ])
+
+@hp.param("model")
+def train(batch_size=32, learning_rate=0.001):
+ print(f"Training with batch_size={batch_size}, lr={learning_rate}")
+
+if __name__ == "__main__":
+ cfg = load_config()
+ with hp.scope(**cfg):
+ train()
+```
+
+**使用方式:**
+```bash
+ENV=dev python main.py # batch_size=8
+ENV=prod python main.py # batch_size=256
+```
+
+---
+
+## 配置继承
+
+### 问题
+你有多个模型变体，它们共享通用设置但在特定参数上有所不同。
+
+### 解决方案
+
+**config/models/base_transformer.toml:**
+```toml
+[model]
+type = "transformer"
+num_layers = 6
+hidden_size = 512
+num_heads = 8
+dropout = 0.1
+activation = "gelu"
+```
+
+**config/models/bert_base.toml:**
+```toml
+[model]
+num_layers = 12
+hidden_size = 768
+num_heads = 12
+vocab_size = 30522
+```
+
+**config/models/bert_large.toml:**
+```toml
+[model]
+num_layers = 24
+hidden_size = 1024
+num_heads = 16
+vocab_size = 30522
+```
+
+**main.py:**
+```python
+import hyperparameter as hp
+
+def load_model_config(model_name: str):
+ """加载带继承的模型配置"""
+ base_config = "config/models/base_transformer.toml"
+ model_config = f"config/models/{model_name}.toml"
+ return hp.config([base_config, model_config])
+
+# 使用
+cfg = load_model_config("bert_large")
+# 结果: num_layers=24, hidden_size=1024, dropout=0.1 (继承自 base)
+```
+
+---
+
+## 密钥管理
+
+### 问题
+你需要管理敏感值（API 密钥、密码），但不能提交到 git。
+
+### 解决方案
+
+**config/app.toml:**
+```toml
+[api]
+base_url = "https://api.example.com"
+timeout = 30
+
+[database]
+host = "${DATABASE_HOST}" # 从环境变量读取
+password = "${DATABASE_PASS}"
+```
+
+**config/secrets.local.toml** (已加入 gitignore):
+```toml
+[api]
+key = "sk-your-actual-api-key"
+
+[database]
+password = "actual-password"
+```
+
+**.gitignore:**
+```
+config/secrets.local.toml
+```
+
+**main.py:**
+```python
+import os
+from pathlib import Path
+import hyperparameter as hp
+
+def load_config_with_secrets():
+ configs = ["config/app.toml"]
+
+ # 如果存在本地密钥文件则加载
+ secrets_file = Path("config/secrets.local.toml")
+ if secrets_file.exists():
+ configs.append(str(secrets_file))
+
+ cfg = hp.config(configs)
+ return cfg
+
+cfg = load_config_with_secrets()
+```
+
+---
+
+## 特性开关
+
+### 问题
+你想在不修改代码的情况下启用/禁用功能。
+
+### 解决方案
+
+**config/features.toml:**
+```toml
+[features]
+new_ui = false
+experimental_model = false
+debug_mode = true
+rate_limiting = true
+
+[features.ab_test]
+enabled = true
+variant = "control" # "control" 或 "treatment"
+```
+
+**main.py:**
+```python
+import hyperparameter as hp
+
+cfg = hp.config("config/features.toml")
+
+with hp.scope(**cfg):
+ # 在代码任何地方检查特性开关
+ if hp.scope.features.new_ui | False:
+ render_new_ui()
+ else:
+ render_old_ui()
+
+ if hp.scope.features.experimental_model | False:
+ model = ExperimentalModel()
+ else:
+ model = StableModel()
+```
+
+**通过命令行切换:**
+```bash
+python main.py -D features.new_ui=true
+```
+

+
+## A/B 测试配置
+
+### 问题
+你需要使用不同的参数配置运行实验。
+
+### 解决方案
+
+```python
+import hyperparameter as hp
+import random
+
+@hp.param("experiment")
+def run_experiment(
+ model_type="baseline",
+ learning_rate=0.001,
+ batch_size=32
+):
+ print(f"Running: {model_type}, lr={learning_rate}, bs={batch_size}")
+ # ... 训练代码 ...
+
+def get_experiment_config(user_id: str):
+ """基于 user_id 的确定性分配"""
+ bucket = hash(user_id) % 100
+
+ if bucket < 50:
+ return {"experiment.model_type": "baseline"}
+ else:
+ return {"experiment.model_type": "new_model", "experiment.learning_rate": 0.0005}
+
+# 使用
+user_config = get_experiment_config("user_123")
+with hp.scope(**user_config):
+ run_experiment()
+```
+
+---
+
+## 多阶段训练
+
+### 问题
+你的训练流水线有多个阶段，每个阶段需要不同的配置。
+
+### 解决方案
+
+```python
+import hyperparameter as hp
+
+@hp.param("train.pretrain")
+def pretrain(lr=0.001, epochs=10, warmup=True):
+ print(f"Pretraining: lr={lr}, epochs={epochs}, warmup={warmup}")
+
+@hp.param("train.finetune")
+def finetune(lr=0.0001, epochs=5, freeze_backbone=True):
+ print(f"Finetuning: lr={lr}, epochs={epochs}, freeze={freeze_backbone}")
+
+@hp.param("train.rl")
+def rl_train(lr=0.00001, episodes=1000, exploration=0.1):
+ print(f"RL Training: lr={lr}, episodes={episodes}, exploration={exploration}")
+
+def run_pipeline():
+ # 阶段 1: 高学习率预训练
+ with hp.scope(**{"train.pretrain.lr": 0.001, "train.pretrain.epochs": 20}):
+ pretrain()
+
+ # 阶段 2: 低学习率微调
+ with hp.scope(**{"train.finetune.lr": 0.00005}):
+ finetune()
+
+ # 阶段 3: RL 训练，探索率递减
+ for stage, exploration in enumerate([0.5, 0.3, 0.1, 0.05]):
+ with hp.scope(**{"train.rl.exploration": exploration}):
+ print(f"--- RL Stage {stage + 1} ---")
+ rl_train()
+
+if __name__ == "__main__":
+ run_pipeline()
+```
+
+这展示了 Hydra 难以实现的**动态作用域**特性。
+
+---
+
+## 最佳实践
+
+### 1. 使用类型提示获得更好的 IDE 支持
+
+```python
+from dataclasses import dataclass
+import hyperparameter as hp
+
+@dataclass
+class ModelConfig:
+ hidden_size: int = 256
+ dropout: float = 0.1
+ activation: str = "relu"
+
+cfg: ModelConfig = hp.config("config.toml", schema=ModelConfig)
+# 现在 cfg.hidden_size 有自动补全了！
+```
+
+### 2. 按关注点组织配置
+
+```
+config/
+├── model/
+│ ├── bert.toml
+│ └── gpt.toml
+├── training/
+│ ├── default.toml
+│ └── distributed.toml
+├── data/
+│ └── preprocessing.toml
+└── base.toml
+```
+
+### 3. 使用插值避免重复 (DRY)
+
+```toml
+[paths]
+root = "/project"
+data = "${paths.root}/data"
+models = "${paths.root}/models"
+logs = "${paths.root}/logs"
+```
+
+### 4. 为配置文件添加注释
+
+```toml
+# BERT 变体的模型配置
+# 参考: https://arxiv.org/abs/1810.04805
+
+[model]
+# Transformer 层数 (base 为 12，large 为 24)
+num_layers = 12
+
+# 隐藏维度 (base 为 768，large 为 1024)
+hidden_size = 768
+```

+# Migrating from Hydra
+
+This guide helps you migrate existing projects from Hydra to Hyperparameter. We'll cover the key differences and provide side-by-side comparisons.
+
+## Why Migrate?
+
+| Aspect | Hydra | Hyperparameter |
+| :--- | :--- | :--- |
+| **Performance** | Pure Python (slower in loops) | Rust backend (6-850x faster) |
+| **Dependencies** | Heavy (antlr4, omegaconf, etc.) | Minimal (only `toml`) |
+| **Config Style** | Top-down (pass `cfg` everywhere) | Bottom-up (inject into functions) |
+| **Scoping** | Static (compose at startup) | Dynamic (change at runtime) |
+
+## Quick Comparison
+
+### Defining Parameters
+
+**Hydra:**
+```python
+# config.yaml
+model:
+ hidden_size: 256
+ dropout: 0.1
+
+# main.py
+import hydra
+from omegaconf import DictConfig
+
+@hydra.main(config_path=".", config_name="config")
+def main(cfg: DictConfig):
+ print(cfg.model.hidden_size) # 256
+```
+
+**Hyperparameter:**
+```python
+# config.toml
+[model]
+hidden_size = 256
+dropout = 0.1
+
+# main.py
+import hyperparameter as hp
+
+@hp.param("model")
+def build_model(hidden_size=128, dropout=0.0):
+ print(hidden_size) # 256 (from config)
+
+if __name__ == "__main__":
+ cfg = hp.config("config.toml")
+ with hp.scope(**cfg):
+ build_model()
+```
+
+### Config Composition (Multiple Files)
+
+**Hydra:**
+```yaml
+# config.yaml
+defaults:
+ - model: resnet
+ - dataset: imagenet
+ - _self_
+
+# model/resnet.yaml
+name: resnet50
+layers: 50
+```
+
+**Hyperparameter:**
+```python
+import hyperparameter as hp
+
+# Load and merge multiple configs (later files override earlier)
+cfg = hp.config(["base.toml", "model/resnet.toml", "dataset/imagenet.toml"])
+
+with hp.scope(**cfg):
+ train()
+```
+
+### Variable Interpolation
+
+**Hydra (OmegaConf):**
+```yaml
+paths:
+ data_dir: /data
+ output_dir: ${paths.data_dir}/outputs
+```
+
+**Hyperparameter:**
+```toml
+[paths]
+data_dir = "/data"
+output_dir = "${paths.data_dir}/outputs"
+```
+
+Both support the same `${key}` syntax!
+
+### Schema Validation
+
+**Hydra (with dataclass):**
+```python
+from dataclasses import dataclass
+from hydra.core.config_store import ConfigStore
+
+@dataclass
+class ModelConfig:
+ hidden_size: int = 256
+ dropout: float = 0.1
+
+cs = ConfigStore.instance()
+cs.store(name="model_config", node=ModelConfig)
+```
+
+**Hyperparameter:**
+```python
+from dataclasses import dataclass
+import hyperparameter as hp
+
+@dataclass
+class ModelConfig:
+ hidden_size: int = 256
+ dropout: float = 0.1
+
+# Direct validation, no ConfigStore needed
+cfg = hp.config("config.toml", schema=ModelConfig)
+print(cfg.hidden_size) # IDE autocomplete works!
+```
+
+### Command Line Overrides
+
+**Hydra:**
+```bash
+python train.py model.hidden_size=512 model.dropout=0.2
+```
+
+**Hyperparameter:**
+```bash
+python train.py -D model.hidden_size=512 -D model.dropout=0.2
+# Or with config file:
+python train.py -C config.toml -D model.hidden_size=512
+```
+
+### Dynamic Scoping (Hyperparameter Exclusive)
+
+This is something Hydra **cannot** do easily:
+
+```python
+import hyperparameter as hp
+
+@hp.param("layer")
+def create_layer(dropout=0.1):
+ return f"Layer with dropout={dropout}"
+
+# Different dropout for different layers - no code change needed!
+with hp.scope(**{"layer.dropout": 0.1}):
+ layer1 = create_layer() # dropout=0.1
+
+with hp.scope(**{"layer.dropout": 0.5}):
+ layer2 = create_layer() # dropout=0.5
+```
+
+## Migration Checklist
+
+- [ ] **Config Files**: Convert YAML to TOML/JSON (or keep YAML with PyYAML installed)
+- [ ] **Decorators**: Replace `@hydra.main` with `@hp.param` + `hp.launch()`
+- [ ] **Config Access**: Replace `cfg.x.y` with `hp.scope.x.y | default` or function injection
+- [ ] **Composition**: Replace `defaults` list with `hp.config([file1, file2])`
+- [ ] **Interpolation**: Same syntax `${key}` works
+- [ ] **CLI**: Replace positional overrides with `-D key=value`
+
+## What You'll Gain
+
+1. **Performance**: 6x faster in dynamic access, 850x faster with injection
+2. **Simplicity**: No ConfigStore, no `@hydra.main` boilerplate
+3. **Flexibility**: Dynamic scoping for complex control flows
+4. **Lightweight**: Fewer dependencies, faster startup
+
+## What You'll Lose (For Now)
+
+1. **Sweeper Plugins**: No built-in Optuna/Ax integration (but easy to implement manually)
+2. **Launcher Plugins**: No SLURM/submitit integration
+3. **Output Management**: No automatic `outputs/date/time` directories
+4. **Tab Completion**: No shell autocomplete for config options
+
+These features may be added in future versions based on community feedback.

+# 从 Hydra 迁移指南
+
+本指南帮助你将现有项目从 Hydra 迁移到 Hyperparameter。我们将介绍两者的关键差异，并提供对照示例。
+
+## 为什么要迁移？
+
+| 方面 | Hydra | Hyperparameter |
+| :--- | :--- | :--- |
+| **性能** | 纯 Python（循环中较慢） | Rust 后端（快 6-850 倍） |
+| **依赖** | 重型（antlr4, omegaconf 等） | 极简（仅需 `toml`） |
+| **配置风格** | 自上而下（到处传递 `cfg`） | 自下而上（注入到函数中） |
+| **作用域** | 静态（启动时组装） | 动态（运行时可变） |
+
+## 快速对比
+
+### 定义参数
+
+**Hydra:**
+```python
+# config.yaml
+model:
+ hidden_size: 256
+ dropout: 0.1
+
+# main.py
+import hydra
+from omegaconf import DictConfig
+
+@hydra.main(config_path=".", config_name="config")
+def main(cfg: DictConfig):
+ print(cfg.model.hidden_size) # 256
+```
+
+**Hyperparameter:**
+```python
+# config.toml
+[model]
+hidden_size = 256
+dropout = 0.1
+
+# main.py
+import hyperparameter as hp
+
+@hp.param("model")
+def build_model(hidden_size=128, dropout=0.0):
+ print(hidden_size) # 256 (来自配置文件)
+
+if __name__ == "__main__":
+ cfg = hp.config("config.toml")
+ with hp.scope(**cfg):
+ build_model()
+```
+
+### 配置组合（多文件）
+
+**Hydra:**
+```yaml
+# config.yaml
+defaults:
+ - model: resnet
+ - dataset: imagenet
+ - _self_
+
+# model/resnet.yaml
+name: resnet50
+layers: 50
+```
+
+**Hyperparameter:**
+```python
+import hyperparameter as hp
+
+# 加载并合并多个配置（后面的文件覆盖前面的）
+cfg = hp.config(["base.toml", "model/resnet.toml", "dataset/imagenet.toml"])
+
+with hp.scope(**cfg):
+ train()
+```
+
+### 变量插值
+
+**Hydra (OmegaConf):**
+```yaml
+paths:
+ data_dir: /data
+ output_dir: ${paths.data_dir}/outputs
+```
+
+**Hyperparameter:**
+```toml
+[paths]
+data_dir = "/data"
+output_dir = "${paths.data_dir}/outputs"
+```
+
+两者都支持相同的 `${key}` 语法！
+
+### Schema 校验
+
+**Hydra (使用 dataclass):**
+```python
+from dataclasses import dataclass
+from hydra.core.config_store import ConfigStore
+
+@dataclass
+class ModelConfig:
+ hidden_size: int = 256
+ dropout: float = 0.1
+
+cs = ConfigStore.instance()
+cs.store(name="model_config", node=ModelConfig)
+```
+
+**Hyperparameter:**
+```python
+from dataclasses import dataclass
+import hyperparameter as hp
+
+@dataclass
+class ModelConfig:
+ hidden_size: int = 256
+ dropout: float = 0.1
+
+# 直接校验，无需 ConfigStore
+cfg = hp.config("config.toml", schema=ModelConfig)
+print(cfg.hidden_size) # IDE 自动补全可用！
+```
+
+### 命令行覆盖
+
+**Hydra:**
+```bash
+python train.py model.hidden_size=512 model.dropout=0.2
+```
+
+**Hyperparameter:**
+```bash
+python train.py -D model.hidden_size=512 -D model.dropout=0.2
+# 或配合配置文件：
+python train.py -C config.toml -D model.hidden_size=512
+```
+
+### 动态作用域（Hyperparameter 独有）
+
+这是 Hydra **很难做到**的：
+
+```python
+import hyperparameter as hp
+
+@hp.param("layer")
+def create_layer(dropout=0.1):
+ return f"Layer with dropout={dropout}"
+
+# 不同层使用不同的 dropout —— 无需修改代码！
+with hp.scope(**{"layer.dropout": 0.1}):
+ layer1 = create_layer() # dropout=0.1
+
+with hp.scope(**{"layer.dropout": 0.5}):
+ layer2 = create_layer() # dropout=0.5
+```
+
+## 迁移清单
+
+- [ ] **配置文件**: 将 YAML 转换为 TOML/JSON（或安装 PyYAML 后继续使用 YAML）
+- [ ] **装饰器**: 将 `@hydra.main` 替换为 `@hp.param` + `hp.launch()`
+- [ ] **配置访问**: 将 `cfg.x.y` 替换为 `hp.scope.x.y | default` 或函数注入
+- [ ] **配置组合**: 将 `defaults` 列表替换为 `hp.config([file1, file2])`
+- [ ] **变量插值**: 相同的 `${key}` 语法可直接使用
+- [ ] **命令行**: 将位置参数覆盖替换为 `-D key=value`
+
+## 你将获得
+
+1. **性能提升**: 动态访问快 6 倍，注入模式快 850 倍
+2. **简洁性**: 无需 ConfigStore，无需 `@hydra.main` 样板代码
+3. **灵活性**: 动态作用域，适应复杂控制流
+4. **轻量级**: 更少依赖，更快启动
+
+## 你将暂时失去
+
+1. **Sweeper 插件**: 无内置 Optuna/Ax 集成（但可轻松手动实现）
+2. **Launcher 插件**: 无 SLURM/submitit 集成
+3. **输出管理**: 无自动 `outputs/date/time` 目录
+4. **Tab 补全**: 无配置选项的 Shell 自动补全
+
+这些功能可能会根据社区反馈在未来版本中添加。
