# ANCP Examples - 実例で学ぶ圧縮記法
|
||
|
||
## 🎯 基本パターン
|
||
|
||
### 1. シンプルなBox定義
|
||
```nyash
|
||
// Nyash (31文字)
|
||
box Point {
|
||
init { x, y }
|
||
}
|
||
|
||
// ANCP (16文字) - 48%削減！
|
||
$Point{#{x,y}}
|
||
```
|
||
|
||
### 2. メソッド付きBox
|
||
```nyash
|
||
// Nyash (118文字)
|
||
box Calculator {
|
||
init { result }
|
||
|
||
birth() {
|
||
me.result = 0
|
||
}
|
||
|
||
add(x, y) {
|
||
me.result = x + y
|
||
return me.result
|
||
}
|
||
}
|
||
|
||
// ANCP (59文字) - 50%削減！
|
||
$Calculator{#{result}b(){m.result=0}add(x,y){m.result=x+y r m.result}}
|
||
```
|
||
|
||
### 3. 継承/デリゲーション
|
||
```nyash
|
||
// Nyash (165文字)
|
||
box Dog from Animal {
|
||
init { name, breed }
|
||
|
||
birth(name, breed) {
|
||
from Animal.init(name)
|
||
me.breed = breed
|
||
}
|
||
|
||
bark() {
|
||
return "Woof! I'm " + me.name
|
||
}
|
||
}
|
||
|
||
// ANCP (87文字) - 47%削減！
|
||
$Dog@Animal{#{name,breed}b(name,breed){@Animal.init(name)m.breed=breed}bark(){r"Woof! I'm"+m.name}}
|
||
```
|
||
|
||
## 🚀 実践的な例
|
||
|
||
### 4. P2Pノード実装
|
||
```nyash
|
||
// Nyash (287文字)
|
||
box P2PNode from NetworkBox {
|
||
init { id, peers, messages }
|
||
|
||
birth(id) {
|
||
me.id = id
|
||
me.peers = new ArrayBox()
|
||
me.messages = new MapBox()
|
||
}
|
||
|
||
connect(peer) {
|
||
me.peers.push(peer)
|
||
peer.addPeer(me)
|
||
return me
|
||
}
|
||
|
||
broadcast(msg) {
|
||
local i = 0
|
||
loop(i < me.peers.length()) {
|
||
me.peers.get(i).receive(msg)
|
||
i = i + 1
|
||
}
|
||
}
|
||
}
|
||
|
||
// ANCP (156文字) - 46%削減！
|
||
$P2PNode@NetworkBox{#{id,peers,messages}b(id){m.id=id m.peers=n ArrayBox()m.messages=n MapBox()}connect(peer){m.peers.push(peer)peer.addPeer(m)r m}broadcast(msg){l i=0 L(i<m.peers.length()){m.peers.get(i).receive(msg)i=i+1}}}
|
||
```
|
||
|
||
### 5. 非同期WebServer
|
||
```nyash
|
||
// Nyash (342文字)
|
||
box WebServer from HttpBox {
|
||
init { port, routes, middleware }
|
||
|
||
birth(port) {
|
||
from HttpBox.init(port)
|
||
me.routes = new MapBox()
|
||
me.middleware = new ArrayBox()
|
||
}
|
||
|
||
route(path, handler) {
|
||
me.routes.set(path, handler)
|
||
return me
|
||
}
|
||
|
||
use(middleware) {
|
||
me.middleware.push(middleware)
|
||
return me
|
||
}
|
||
|
||
async start() {
|
||
await from HttpBox.listen(me.port)
|
||
print("Server running on port " + me.port)
|
||
}
|
||
}
|
||
|
||
// ANCP (183文字) - 46%削減！
|
||
$WebServer@HttpBox{#{port,routes,middleware}b(port){@HttpBox.init(port)m.routes=n MapBox()m.middleware=n ArrayBox()}route(path,handler){m.routes.set(path,handler)r m}use(middleware){m.middleware.push(middleware)r m}async start(){await @HttpBox.listen(m.port)print("Server running on port"+m.port)}}
|
||
```
|
||
|
||
## 💡 高度なパターン
|
||
|
||
### 6. エラーハンドリング
|
||
```nyash
|
||
// Nyash (198文字)
|
||
box SafeCalculator {
|
||
divide(a, b) {
|
||
if b == 0 {
|
||
return new ErrorBox("Division by zero")
|
||
} else {
|
||
return new ResultBox(a / b)
|
||
}
|
||
}
|
||
}
|
||
|
||
// ANCP (93文字) - 53%削減！
|
||
$SafeCalculator{divide(a,b){?b==0{r n ErrorBox("Division by zero")}:{r n ResultBox(a/b)}}}
|
||
```
|
||
|
||
### 7. ジェネリック風パターン
|
||
```nyash
|
||
// Nyash (245文字)
|
||
box Container {
|
||
init { items, type }
|
||
|
||
birth(type) {
|
||
me.items = new ArrayBox()
|
||
me.type = type
|
||
}
|
||
|
||
add(item) {
|
||
if item.type() == me.type {
|
||
me.items.push(item)
|
||
return true
|
||
}
|
||
return false
|
||
}
|
||
}
|
||
|
||
// ANCP (124文字) - 49%削減！
|
||
$Container{#{items,type}b(type){m.items=n ArrayBox()m.type=type}add(item){?item.type()==m.type{m.items.push(item)r true}r false}}
|
||
```
|
||
|
||
## 🎮 完全なアプリケーション例
|
||
|
||
### 8. Todoアプリ（フル実装）
|
||
```nyash
|
||
// Nyash (562文字)
|
||
box TodoApp {
|
||
init { todos, nextId }
|
||
|
||
birth() {
|
||
me.todos = new ArrayBox()
|
||
me.nextId = 1
|
||
}
|
||
|
||
addTodo(text) {
|
||
local todo = new MapBox()
|
||
todo.set("id", me.nextId)
|
||
todo.set("text", text)
|
||
todo.set("done", false)
|
||
|
||
me.todos.push(todo)
|
||
me.nextId = me.nextId + 1
|
||
|
||
return todo.get("id")
|
||
}
|
||
|
||
toggleTodo(id) {
|
||
local i = 0
|
||
loop(i < me.todos.length()) {
|
||
local todo = me.todos.get(i)
|
||
if todo.get("id") == id {
|
||
todo.set("done", not todo.get("done"))
|
||
return true
|
||
}
|
||
i = i + 1
|
||
}
|
||
return false
|
||
}
|
||
|
||
listTodos() {
|
||
return me.todos
|
||
}
|
||
}
|
||
|
||
// ANCP (296文字) - 47%削減！
|
||
$TodoApp{#{todos,nextId}b(){m.todos=n ArrayBox()m.nextId=1}addTodo(text){l todo=n MapBox()todo.set("id",m.nextId)todo.set("text",text)todo.set("done",false)m.todos.push(todo)m.nextId=m.nextId+1 r todo.get("id")}toggleTodo(id){l i=0 L(i<m.todos.length()){l todo=m.todos.get(i)?todo.get("id")==id{todo.set("done",not todo.get("done"))r true}i=i+1}r false}listTodos(){r m.todos}}
|
||
```

|
||
| Calculator | 118 | 59 | 50% |
|
||
| Dog | 165 | 87 | 47% |
|
||
| P2PNode | 287 | 156 | 46% |
|
||
| WebServer | 342 | 183 | 46% |
|
||
| SafeCalculator | 198 | 93 | 53% |
|
||
| Container | 245 | 124 | 49% |
|
||
| TodoApp | 562 | 296 | 47% |
|
||
|

**平均削減率: 48.3%**
|
||
|
||
## 🔍 パターン分析
|
||
|
||
### 最も効果的な変換
|
||
1. `return` → `r` (83%削減)
|
||
2. `local` → `l` (80%削減)
|
||
3. `new` → `n` (67%削減)
|
||
4. `box` → `$` (75%削減)
|
||
5. `me` → `m` (50%削減)
|
||
|
||
### 圧縮のコツ
|
||
- 空白を最小限に（セミコロン不要）
|
||
- 中括弧の直後に内容を書く
|
||
- 演算子の前後の空白を省略
|
||
- 文字列連結の空白も省略可能
