Generate MDPT Presentation

You are generating a markdown presentation for MDPT (Markdown Presentation Tool built with RustPixel).

Topic / Requirements: $ARGUMENTS

Output

Write the generated markdown to gen.md in the current working directory.

MDPT Format Specification

YAML Frontmatter (required at top)

---
title: Presentation Title
author: Author Name
theme: dark
transition: cycle
title_animation: typewriter
code_theme: base16-ocean.dark
margin: 4
height: 26
transition_duration: 0.2
---

Available values:

• theme: dark, light
• transition: cycle, fade, slide_left, slide_right, slide_up, slide_down
• title_animation: typewriter, spotlight, wave, fadein
• code_theme: any syntect theme (base16-ocean.dark, Solarized (dark), InspiredGitHub)
• margin: horizontal margin in cells (default 2)
• width: virtual canvas width in cells (default 80)
• height: virtual canvas height in cells (default 24, use 26-30 for dense content)

Slide Separator

Use --- on its own line to separate slides.

Headings

• # H1 — title slides and ending slides only
• ## H2 — normal slide title (most slides use this)
• ### H3 — section heading within a slide

Lists

* Unordered item (supports nesting with indentation)
  * Nested item
    * Deeper nesting

1. Ordered item
2. Second item

Code Blocks

```rust +line_numbers
fn main() {
    println!("Hello!");
}
```

Options after language name: +line_numbers, +no_background

Dynamic highlighting (press Space to cycle groups):

```rust {1-3|5-8|all} +line_numbers
// lines 1-3 highlighted first
// then lines 5-8
// then all
```

Tables

| Header 1 | Header 2 | Header 3 |
|:---------|:--------:|---------:|
| Left     | Center   | Right    |

Block Quotes and Alerts

> Regular quote text

> [!note]
> This is a helpful note.

> [!caution]
> Be careful with this!

Special MDPT Directives (HTML comments)

<!-- pause -->              Incremental display (next content appears on key press)
<!-- divider -->             Horizontal divider line
<!-- spacer: 2 -->          Add N blank lines
<!-- jump_to_middle -->     Center next content vertically (for title/ending slides)

Column Layout

<!-- column_layout: [1, 1] -->
<!-- column: 0 -->
Left column content here
<!-- column: 1 -->
Right column content here
<!-- reset_layout -->

Weight ratio [1, 1] means equal width. Use [2, 1] for 2:1 ratio.

Text Animations

<!-- anim: spotlight -->
Text with spotlight animation (per-char highlight pulse)

<!-- anim: wave -->
Text with wave animation (sinusoidal scale)

<!-- anim: fadein -->
Text with fade-in animation (chars reveal left-to-right)

<!-- anim: typewriter -->
Text with typewriter animation (chars appear one by one)

Charts (fenced code blocks)

Line Chart:

```linechart
title: Monthly Revenue
x: [Jan, Feb, Mar, Apr, May]
y: [120, 200, 150, 300, 280]
y2: [80, 150, 120, 200, 250]
height: 12
```

Bar Chart:

```barchart
title: Programming Languages
labels: [Rust, Go, Python, JS]
values: [95, 72, 88, 78]
height: 14
```

Pie Chart:

```piechart
title: Market Share
labels: [Chrome, Safari, Firefox, Edge]
values: [65, 18, 7, 5]
radius: 20
```

Mermaid Flowchart

```mermaid
graph TD
A[Start] --> B[Process]
B --> C{Decision}
C -->|Yes| D[Result]
C -->|No| E[Other]
```

Supports graph TD (top-down) and graph LR (left-right). Node shapes: [rect], (round), {diamond}.

Mermaid Sequence Diagram

```mermaid
sequenceDiagram
    participant C as Client
    participant S as Server
    C->>S: Request
    S-->>C: Response
```

• participant ID as Label declares a participant (optional, auto-created from messages)
• ->> solid arrow, -->> dashed arrow
• A->>B: message sends message from A to B

Images

<!-- image_pos: [16, 10] -->
![alt](filename.ssf)

Supports .pix and .ssf (sequence frame) image formats.

Guidelines

1. Generate 18-30 slides with rich, substantial content
2. First slide: title slide using # Title with a subtitle line
3. Last slide: ending slide using <!-- jump_to_middle --> and # Thank You! or similar
4. Use varied elements: lists, code blocks, tables, charts, columns, quotes, animations
5. Use <!-- pause --> for progressive reveal on content-heavy slides
6. Include at least one code block, one table, and one chart
7. Each slide should fit within the configured height (typically 24-30 rows minus margins)
8. If a topic has too much content for one slide, split into multiple slides
9. Use the language matching the topic (Chinese topic → Chinese content, English → English)
10. Use <!-- anim: ... --> sparingly for emphasis (1-3 times in the whole presentation)
11. Output only the raw markdown with YAML frontmatter, no wrapping fences
12. Read references/examples/demo.md first as a reference for syntax and style

Process

1. First read references/examples/demo.md to understand the format in practice
2. If the user provided a document/file path, read it to extract content
3. Generate the MDPT markdown presentation
4. Write to gen.md in the current working directory
5. Report the number of slides generated
