# 生拼圖
用 jigsawR 包之統一 API 生拼圖。
## 用
- 某型與配置造拼圖 SVG
- 不同參數試生
- 生樣品供文檔或示
- 用 geom_puzzle_*() 造 ggplot2 拼圖視覺
## 入
- **必**:拼圖型(`"rectangular"`、`"hexagonal"`、`"concentric"`、`"voronoi"`、`"random"`、`"snic"`)
- **必**:格維(依型:`c(cols, rows)` 或 `c(rings)`)
- **可**:尺寸 mm(默依型異)
- **可**:種(可復性,默 42)
- **可**:偏移(0=互扣,>0=分離)
- **可**:布局(`"grid"` 或 `"repel"`,rect)
- **可**:融組(PILES 符號串)
## 行
### 一:讀配約束
```bash
R_EXE="/mnt/c/Program Files/R/R-4.5.0/bin/Rscript.exe"
"$R_EXE" -e "cat(yaml::yaml.load_file('inst/config.yml')[['{TYPE}']]$grid$max)"
```
或直讀 `inst/config.yml` 察所擇型之有效範圍。
得:所擇型之 grid、size、tabsize 諸參之最小最大已知。
敗:`config.yml` 缺或型鍵不存→查於 jigsawR 根且包至少建過一次。
### 二:定型與參
用戶請求映為有效 `generate_puzzle()` 引數:
| Type | grid | size | Extra params |
|---|---|---|---|
| rectangular | `c(cols, rows)` | `c(width, height)` mm | `offset`, `layout`, `tabsize` |
| hexagonal | `c(rings)` | `c(diameter)` mm | `do_warp`, `do_trunc`, `tabsize` |
| concentric | `c(rings)` | `c(diameter)` mm | `center_shape`, `tabsize` |
| voronoi | `c(cols, rows)` | `c(width, height)` mm | `n_interior`, `tabsize` |
| random | `c(cols, rows)` | `c(width, height)` mm | `n_interior`, `tabsize` |
| snic | `c(cols, rows)` | `c(width, height)` mm | `n_interior`, `compactness`, `tabsize` |
得:請求映為 `generate_puzzle()` 有效引數,型、grid、size 皆於 config.yml 範圍內。
敗:參形式不明→參表。矩形與 voronoi 用 `c(cols, rows)`;六與同心用 `c(rings)`。
### 三:造 R 腳本
書腳本檔(複雜命令勝於 `-e`):
```r
library(jigsawR)
result <- generate_puzzle(
type = "rectangular",
seed = 42,
grid = c(3, 4),
size = c(400, 300),
offset = 0,
layout = "grid"
)
cat("Pieces:", length(result$pieces), "\n")
cat("SVG length:", nchar(result$svg_content), "\n")
cat("Files:", paste(result$files, collapse = ", "), "\n")
```
存於臨時腳本。
得:R 腳本檔存於臨時位,含 `library(jigsawR)`、`generate_puzzle()` 全參調用、診斷輸出。
敗:語法誤→查字串皆引、數值向量用 `c()`。複雜殼轉義→必用腳本檔。
### 四:經 WSL R 行
```bash
R_EXE="/mnt/c/Program Files/R/R-4.5.0/bin/Rscript.exe"
"$R_EXE" /path/to/script.R
```
得:腳本無誤完成。SVG 寫於 `output/`。
敗:察 renv 已復(`renv::restore()`)。驗包已載(`devtools::load_all()`)。勿用 `--vanilla` 旗(renv 需 .Rprofile)。
### 五:驗出
- SVG 檔存於 `output/`
- SVG 內容以 `<?xml` 或 `<svg` 開
- 片數符:cols * rows(矩)、環式(六/同心)
- ggplot2 法→驗圖對象無誤繪
得:SVG 檔存於 `output/`,內容以 `<?xml` 或 `<svg` 開,片數符格規格(矩用 cols*rows,六/同心用環式)。
敗:SVG 檔缺→察 `output/` 存。片數誤→驗格維合型式。ggplot2 出→以 `tryCatch()` 包察繪無誤。
### 六:存出
生成檔默存 `output/`。`result` 對象含:
- `$svg_content`:生 SVG 串
- `$pieces`:片數據列
- `$canvas_size`:維
- `$files`:寫檔之徑
得:`result` 對象含 `$svg_content`、`$pieces`、`$canvas_size`、`$files`。`$files` 列之檔存於磁。
敗:`$files` 空→拼圖或僅生於內存。顯存以 `writeLines(result$svg_content, "output/puzzle.svg")`。
## 驗
- [ ] 腳本無誤行
- [ ] SVG 檔乃良構 XML
- [ ] 片數符格規格
- [ ] 同種生同出(可復)
- [ ] 參於 config.yml 約束內
## 忌
- **用 `--vanilla` 旗**:破 renv 啟動。絕勿用
- **複雜 `-e` 命令**:用腳本檔;殼轉義致 Exit 5
- **Grid 與 size 混**:格乃片數,size 乃物理 mm 維
- **偏移語義**:0=組裝,正=散裂片
- **SNIC 無包**:snic 型需 `snic` 包已裝
## 參
- `add-puzzle-type`
- `validate-piles-notation`
- `run-puzzle-tests`
- `write-testthat-tests`
