Wiki PPT

Generate a presentation from wiki content. Two output formats available.

Option 1: Marp (default — stays in Obsidian)

Marp turns markdown into slide decks. Obsidian renders with the Marp Slides plugin.

1. Read relevant wiki pages based on the topic
2. Design slide structure:
   • Title + subtitle
   • Context / background (1-2 slides)
   • Key findings (3-7 slides, one main point each)
   • Comparisons / analysis (if relevant)
   • Open questions / next steps
3. Write Marp markdown to ppt/<topic>.md:

marp: true
theme: default
paginate: true

# Title

Subtitle or context


# Key Finding 1

- Point with [[wikilink]] citation
- Supporting evidence


![bg right:40%](wiki/assets/chart.png)

# Visual Analysis

Insights from the chart


# Open Questions

- What remains to investigate
- Next sources to ingest

4. Tell user to open in Obsidian → Marp plugin renders as presentation
5. Export options: marp ppt/<topic>.md --pptx or --pdf via Marp CLI

Option 2: PPTX (for external sharing)

1. Read relevant wiki pages
2. Design slide structure (same as above)
3. Generate PPTX via python-pptx (pip install python-pptx if needed)
4. Include diagrams from wiki/assets/
5. Save to outputs/<topic>-<date>.pptx

Use PPTX only when user specifically needs it for external sharing. Default to Marp.

更新 slide-index.md

產出投影片後，在 wiki/references/slide-index.md 的表格追加一行：

| MM-DD | `ppt/<topic>/` | 主題描述 | 頁數 | [[concepts/xxx]], [[entities/yyy]] |

Log Entry
