# 增拼類
於 jigsawR 諸接點建新拼類。
## 用
- 增全新拼類於包→用
- 循 CLAUDE.md 十點清單→用
- 端至端勿漏→用
## 入
- **必**:類名(小寫,例 `"triangular"`)
- **必**:幾何述(片如何形如何排)
- **必**:是否需外包(入 Suggests)
- **可**:標參外之參(grid、size、seed、tabsize、offset)
- **可**:實或算之參考
## 行
### 一:建核拼模
建 `R/<type>_puzzle.R` 內生函:
```r
#' Generate <type> puzzle pieces (internal)
#' @noRd
generate_<type>_pieces_internal <- function(params, seed) {
# 1. Initialize RNG state
# 2. Generate piece geometries
# 3. Build edge paths (SVG path data)
# 4. Compute adjacency
# 5. Return list: pieces, edges, adjacency, metadata
}
```
循 `R/voronoi_puzzle.R` 或 `R/snic_puzzle.R` 之構。
得:函返列含 `$pieces`、`$edges`、`$adjacency`、`$metadata`。
敗:比 `generate_voronoi_pieces_internal()` 之返構以識缺元或型誤。
### 二:接 jigsawR_clean.R
改 `R/jigsawR_clean.R`:
1. 入 `"<type>"` 於 `valid_types`
2. 增類專參析於 params 區
3. 增類專限驗
4. 增檔名前綴映(例 `"<type>"` → `"<type>_"`)
```r
# In valid_types
valid_types <- c("rectangular", "hexagonal", "concentric", "voronoi", "snic", "<type>")
```
得:`generate_puzzle(type = "<type>")` 受而無「unknown type」誤。
敗:驗類串入 `valid_types` 字字相符,且參析涵諸類專參。
### 三:接 unified_piece_generation.R
改 `R/unified_piece_generation.R`:
1. 增分派於 `generate_pieces_internal()`
2. 若類支 PILES 記法則增融處
```r
# In the switch/dispatch
"<type>" = generate_<type>_pieces_internal(params, seed)
```
得:類分派時片得生。
敗:驗分派串字字相符且 `generate_<type>_pieces_internal` 已定且自拼模出。
### 四:接 piece_positioning.R
改 `R/piece_positioning.R`:
增類定位分派。多類用共定位邏輯,少數需專處。
得:`apply_piece_positioning()` 處新類無誤、片置正座。
敗:察新類需專定位邏輯否或可重用共路。如默路不適則增分派。
### 五:接 unified_renderer.R
改 `R/unified_renderer.R`:
1. 增繪於 `render_puzzle_svg()`
2. 增邊路函:`get_<type>_edge_paths()`
3. 增片名函:`get_<type>_piece_name()`
得:新類 SVG 出,片廓、邊路皆正。
敗:驗 `get_<type>_edge_paths()` 返有效 SVG 路且 `get_<type>_piece_name()` 出各片獨識。
### 六:接 adjacency_api.R
改 `R/adjacency_api.R`:
增鄰分派使 `get_neighbors()`、`get_adjacency()` 用於新類。
得:`get_neighbors(result, piece_id)` 返任片之正鄰。
敗:察鄰分派返正構。以小格驗、手核鄰係對幾何。
### 七:增 ggpuzzle 幾層
改 `R/geom_puzzle.R`:
以 `make_puzzle_layer()` 廠建 `geom_puzzle_<type>()`:
```r
#' @export
geom_puzzle_<type> <- function(mapping = NULL, data = NULL, ...) {
make_puzzle_layer(type = "<type>", mapping = mapping, data = data, ...)
}
```
得:`ggplot() + geom_puzzle_<type>(aes(...))` 繪而無誤。
敗:驗 `make_puzzle_layer()` 受正類串且 geom 函於 NAMESPACE 經 `@export` 出。
### 八:增 stat 分派
改 `R/stat_puzzle.R`:
1. 增類專默參
2. 增分派於 `compute_panel()`
得:stat 層算幾正、出預期多角。
敗:察 `compute_panel()` 分派返必欄之數框(`x`、`y`、`group`、`piece_id`)且默參合新類。
### 九:更 DESCRIPTION
改 `DESCRIPTION`:
1. 增新類於 Description 文
2. 新包入 `Suggests:`(若外依)
3. 更 `Collate:` 含新 R 檔(字序)
得:`devtools::document()` 成。無未列檔之 NOTE。
敗:察新 R 檔列於 `Collate:` 字序且新 Suggests 包字字相符附版限。
### 十:更 config.yml
改 `inst/config.yml`:
增新類默與限:
```yaml
<type>:
grid:
default: [3, 3]
min: [2, 2]
max: [20, 20]
size:
default: [300, 300]
min: [100, 100]
max: [2000, 2000]
tabsize:
default: 20
min: 5
max: 50
# Add type-specific params here
```
得:配為有效 YAML。默生可用拼於 `generate_puzzle()`。
敗:以 `yaml::yaml.load_file("inst/config.yml")` 驗 YAML。確默 grid 與 size 出合理拼。
### 十一:擴 Shiny 應
改 `inst/shiny-app/app.R`:
1. 增新類於 UI 類選
2. 增類專參之條件 UI 板
3. 增伺端生邏
得:Shiny 應於下拉示新類、選則生拼。
敗:察類入 UI 選之 `choices`,類專條件板用 `conditionalPanel(condition = "input.type == '<type>'")`,伺端傳正參。
### 十二:建測套
建 `tests/testthat/test-<type>-puzzles.R`:
```r
test_that("<type> puzzle generates correct piece count", { ... })
test_that("<type> puzzle respects seed reproducibility", { ... })
test_that("<type> adjacency returns valid neighbors", { ... })
test_that("<type> fusion merges pieces correctly", { ... })
test_that("<type> geom layer renders without error", { ... })
test_that("<type> SVG output is well-formed", { ... })
test_that("<type> config constraints are enforced", { ... })
```
若類需外包則以 `skip_if_not_installed()` 包之。
得:諸測皆過。除外依缺則無跳。
敗:分察各接。常缺分派——行 `grep -rn "switch\|valid_types" R/` 尋諸分派處。
## 驗
- [ ] `generate_puzzle(type = "<type>")` 出有效
- [ ] 十接點皆正接
- [ ] `devtools::test()` 含新測過
- [ ] `devtools::check()` 零誤零警
- [ ] Shiny 應繪新類
- [ ] 配限獲行(min/max 驗)
- [ ] 鄰、融皆正
- [ ] ggpuzzle geom 繪而無誤
- [ ] `devtools::document()` 成(NAMESPACE 更)
## 忌
- **缺分派**:忘十餘檔之一致默敗或「unknown type」誤
- **負數 strsplit**:以 `paste(a, b, sep = "-")` 建鄰鍵時負片標出 `"1--1"`。用 `"|"` 分、以 `"\\|"` 析
- **用 `cat()` 出**:恆用 `cli` 包記裝(`log_info`、`log_warn` 等)
- **Collate 序**:DESCRIPTION Collate 須字序或依序
- **Config.yml 式**:確 YAML 有效;以 `yaml::yaml.load_file("inst/config.yml")` 驗
## 參
- `generate-puzzle` — 建後測新類
- `run-puzzle-tests` — 行全測套驗接
- `validate-piles-notation` — 以新類測融
- `write-testthat-tests` — 通測寫紋
- `write-roxygen-docs` — 文新 geom 函
