Covers theme selection (9 themes including 4 colorblind-safe), output modes (console, file, clipboard, raw), interactive features (clickable nodes, source info), and embedding in README, Quarto, and R Markdown. Use after annotating source files and ready to produce a visual diagram, when regenerating a diagram after workflow changes, or when switching themes or output formats for different audiences. license: MIT allowed-tools: Read Write Edit Bash Grep Glob metadata: author: Philipp Thoss version: "1.0" domain: workflow-visualization complexity: basic language: R tags: putior, mermaid, diagram, theme, visualization, flowchart

生工作流圖

由 putior 工作流數據生題 Mermaid 流程圖並嵌文檔。

用

• 源檔標註後欲出視覺圖
• 工作流變後重生圖
• 為不同受眾換題或出格式
• 嵌工作流圖於 README、Quarto、R Markdown

入

• 必：工作流數據（由 put()、put_auto()、put_merge()）
• 可：題名（默 "light"；選：light、dark、auto、minimal、github、viridis、magma、plasma、cividis）
• 可：出目標：控台、檔徑、剪貼、原串
• 可：交互：show_source_info、enable_clicks

行

一：取工作流數據

由三源之一取工作流數據。

library(putior)

# From manual annotations
workflow <- put("./src/")

# From manual annotations, excluding specific files
workflow <- put("./src/", exclude = c("build-workflow\\.Rquot;, "test_"))

# From auto-detection only
workflow <- put_auto("./src/")

# From merged (manual + auto)
workflow <- put_merge("./src/", merge_strategy = "supplement")

工作流數據幀或含來自標註之 node_type 列。節點型控 Mermaid 形：

node_type	Mermaid Shape	Use Case
"input"	Stadium ([...])	Data sources, configuration files
"output"	Subroutine [[...]]	Generated artifacts, reports
"process"	Rectangle [...]	Processing steps (default)
"decision"	Diamond {...}	Conditional logic, branching
"start" / "end"	Stadium ([...])	Entry/terminal nodes

各 node_type 亦得相應 CSS 類（如 class nodeId input;）供題化。

得：數據幀至少一列，含 id、label，可選 input、output、source_file、node_type 列。

敗：數據幀空→無標註或模式。先行 analyze-codebase-workflow，或驗標註合語法用 put("./src/", validate = TRUE)。

二：擇題與選項

依目標受眾擇題。

List all available themes:

get_diagram_themes()

Standard themes

• "light" — Default, bright colors
• "dark" — For dark mode environments
• "auto" — GitHub-adaptive with solid colors
• "minimal" — Grayscale, print-friendly
• "github" — Optimized for GitHub README files

Colorblind-safe themes (viridis family)

• "viridis" — Purple→Blue→Green→Yellow, general accessibility
• "magma" — Purple→Red→Yellow, high contrast for print
• "plasma" — Purple→Pink→Orange→Yellow, presentations
• "cividis" — Blue→Gray→Yellow, maximum accessibility (no red-green)

他參：

• direction：圖向——"TD"（上下，默）、"LR"（左右）、"RL"、"BT"
• show_artifacts：TRUE/FALSE——示物件節點（檔、數據）；大工作流或噪（如 16+ 額外節點）
• show_workflow_boundaries：TRUE/FALSE——各源檔節點裹入 Mermaid 子圖
• source_info_style：源檔訊於節點顯示法（如副題）
• node_labels：節點標籤文格式

得：題名印出。依脈絡擇一。

敗：題名未識→put_diagram() 回退 "light"。察拼法。

三：用 put_theme() 自定調色（可選）

九內建題不合→以 put_theme() 造自定題。

# Create custom palette — unspecified types inherit from base theme
cyberpunk <- put_theme(
  base = "dark",
  input    = c(fill = "#1a1a2e", stroke = "#00ff88", color = "#00ff88"),
  process  = c(fill = "#16213e", stroke = "#44ddff", color = "#44ddff"),
  output   = c(fill = "#0f3460", stroke = "#ff3366", color = "#ff3366"),
  decision = c(fill = "#1a1a2e", stroke = "#ffaa33", color = "#ffaa33")
)

# Use the palette parameter (overrides theme when provided)
mermaid_content <- put_diagram(workflow, palette = cyberpunk, output = "raw")
writeLines(mermaid_content, "workflow.mmd")

put_theme() 受 input、process、output、decision、artifact、start、end 節點型。各取命名向量 c(fill = "#hex", stroke = "#hex", color = "#hex")。未設型承基題。

得：Mermaid 出具自定 classDef 行。node_type 之形保，僅色變。諸節點型用 stroke-width:2px——put_theme() 當前未支援覆寫。

敗：調色非 putior_theme 類→put_diagram() 發明誤。確傳 put_theme() 返值，非原列。

**回退——手動 classDef 替換：**欲 put_theme() 外之細控（如各型畫筆寬），用基題生後手換 classDef：

mermaid_content <- put_diagram(workflow, theme = "dark", output = "raw")
lines <- strsplit(mermaid_content, "\n")[[1]]
lines <- lines[!grepl("^\\s*classDef ", lines)]
custom_defs <- c("  classDef input fill:#1a1a2e,stroke:#00ff88,stroke-width:3px,color:#00ff88")
mermaid_content <- paste(c(lines, custom_defs), collapse = "\n")

四：生 Mermaid 出

按所需出模生圖。

# Print to console (default)
cat(put_diagram(workflow, theme = "github"))

# Save to file
writeLines(put_diagram(workflow, theme = "github"), "docs/workflow.md")

# Get raw string for embedding
mermaid_code <- put_diagram(workflow, output = "raw", theme = "github")

# With source file info (shows which file each node comes from)
cat(put_diagram(workflow, theme = "github", show_source_info = TRUE))

# With clickable nodes (for VS Code, RStudio, or file:// protocol)
cat(put_diagram(workflow,
  theme = "github",
  enable_clicks = TRUE,
  click_protocol = "vscode"  # or "rstudio", "file"
))

# Full-featured
cat(put_diagram(workflow,
  theme = "viridis",
  show_source_info = TRUE,
  enable_clicks = TRUE,
  click_protocol = "vscode"
))

得：有效 Mermaid 碼以 flowchart TD（或依向為 LR）開。諸節點以箭頭連示數據流。

敗：出為 flowchart TD 無節點→數據幀空。連缺→察諸節點間出檔名符入檔名。

五：嵌目標文檔

將圖插入適文檔格式。

GitHub README（```mermaid 碼欄）：

## Workflow

```mermaid
flowchart TD
  A["Extract Data"] --> B["Transform"]
  B --> C["Load"]
```

Quarto 文（原生 mermaid 塊經 knit_child）：

# Chunk 1: Generate code (visible, foldable)
workflow <- put("./src/")
mermaid_code <- put_diagram(workflow, output = "raw", theme = "github")

# Chunk 2: Output as native mermaid chunk (hidden)
#| output: asis
#| echo: false
mermaid_chunk <- paste0("```{mermaid}\n", mermaid_code, "\n```")
cat(knitr::knit_child(text = mermaid_chunk, quiet = TRUE))

R Markdown（mermaid.js CDN 或 DiagrammeR）：

DiagrammeR::mermaid(put_diagram(workflow, output = "raw"))

得：圖於目標格式正確繪。GitHub 原生繪 mermaid 碼欄。

敗：GitHub 不繪→確碼欄用精確 ```mermaid（無額屬性）。Quarto→用 knit_child() 法；{mermaid} 塊不支援變量插值。

驗

• put_diagram() 生有效 Mermaid（以 flowchart 開）
• 諸預期節點皆現於圖
• 連節點間之數據流連（箭頭）具
• 所選題已應（察出之 init 塊含題特色）
• 圖於目標格式（GitHub、Quarto 等）正確繪

忌

• 空圖：常因 put() 返無列。察標註存且合語法
• 諸節點皆斷：出檔名須精確符入檔名（含副檔）供 putior 連。data.csv 與 Data.csv 異
• 題於 GitHub 不顯：GitHub 之 mermaid 繪器題支援有限。"github" 題專設。%%{init:...}%% 題塊或被部分繪器忽
• Quarto mermaid 變量插值：Quarto 之 {mermaid} 塊不直支 R 變量。用步五之 knit_child() 法
• 可點節點不作：點指令需支 Mermaid 交互事件之繪器。GitHub 靜繪器不支點。用本機 Mermaid 繪器或 putior Shiny 沙盒
• 自參元管線檔：掃含生圖建腳本之目錄→子圖 ID 重並 Mermaid 誤。用 exclude 於掃時略：

  workflow <- put("./src/", exclude = c("build-workflow\\.Rquot;, "build-workflow\\.jsquot;))
  

• show_artifacts = TRUE 過噪：大項目或生眾物件節點（10-20+），亂圖。用 show_artifacts = FALSE 並倚 node_type 標註顯標關鍵入出
