ppt-rs

The Rust library for generating PowerPoint presentations that actually works.

While other Rust crates for PPTX generation are incomplete, broken, or abandoned, ppt-rs generates valid, production-ready PowerPoint files that open correctly in PowerPoint, LibreOffice, Google Slides, and other Office applications.

🎯 Convert Markdown to PowerPoint in seconds - Write your slides in Markdown, get a professional PPTX file. No PowerPoint needed.

Why ppt-rs?

• 🚀 Markdown to PPTX - Write slides in Markdown, get PowerPoint files. Perfect for developers.
• ✅ Actually works - Generates valid PPTX files that open in all major presentation software
• ✅ Complete implementation - Full ECMA-376 Office Open XML compliance
• ✅ Type-safe API - Rust's type system ensures correctness
• ✅ Simple & intuitive - Builder pattern with fluent API

Quick Start

Markdown to PowerPoint (Recommended)

The easiest way to create presentations: write Markdown, get PowerPoint.

1. Create a Markdown file:

# Introduction
- Welcome to the presentation
- Today's agenda

# Key Points
- First important point
- Second important point
- Third important point

# Conclusion
- Summary of takeaways
- Next steps

2. Convert to PPTX:

# Auto-generates slides.pptx
pptcli md2ppt slides.md

# Or specify output
pptcli md2ppt slides.md presentation.pptx

# With custom title
pptcli md2ppt slides.md --title "My Presentation"

That's it! You now have a valid PowerPoint file that opens in PowerPoint, Google Slides, LibreOffice, and more.

Library (Simple API)

use ppt_rs::prelude::*;

fn main() -> std::result::Result<(), Box<dyn std::error::Error>> {
    // Quick presentation with macros
    let pptx = pptx!("My Presentation")
        .title_slide("Welcome", "Introduction to ppt-rs")
        .slide("Key Points", vec!["Point 1", "Point 2", "Point 3"])
        .shapes_slide("Shapes", vec![
            shapes::rect(inches(1.0), inches(2.0), inches(2.0), inches(1.0))
                .with_fill(ShapeFill::new(colors::BLUE))
                .with_text("Hello"),
        ])
        .build()?;
    
    std::fs::write("output.pptx", pptx)?;
    Ok(())
}

Library (Full API)

use ppt_rs::generator::{SlideContent, create_pptx_with_content};

fn main() -> std::result::Result<(), Box<dyn std::error::Error>> {
    let slides = vec![
        SlideContent::new("Introduction")
            .add_bullet("Welcome")
            .add_bullet("Agenda"),
        SlideContent::new("Key Points")
            .add_bullet("Point 1")
            .add_bullet("Point 2"),
    ];
    
    let pptx = create_pptx_with_content("My Presentation", slides)?;
    std::fs::write("output.pptx", pptx)?;
    Ok(())
}

Features

Core Capabilities

• Slides - Multiple layouts (title-only, two-column, blank, etc.)

Markdown Format

The Markdown format supports rich content:

Code Block Syntax Highlighting: Code blocks are rendered with Solarized Dark theme colors:

• Blue - Keywords (fn, let, def, class)
• Yellow - Function names
• Cyan - Strings
• Green - Operators, macros
• Violet - Numbers
• Orange - Format specifiers

Example:

# Introduction
- Welcome to the presentation
- **Key point** with emphasis

# Data Table
| Product | Sales |
|---------|-------|
| Widget  | $100  |

> Speaker notes go here

# Code Example
```python
print("Hello!")

Conclusion

• Summary
• Q&A

Convert with: `pptcli md2ppt presentation.md` → `presentation.pptx`

## CLI Commands

### Validate PPTX Files

Validate a PPTX file for ECMA-376 compliance:

```bash
pptcli validate presentation.pptx

This checks:

• ZIP archive integrity
• Required XML files presence
• XML validity
• Relationships structure

Show Presentation Information

pptcli info presentation.pptx

Repair PPTX Files

Repair damaged or corrupted PPTX files:

use ppt_rs::oxml::repair::PptxRepair;

// Open and validate
let mut repair = PptxRepair::open("damaged.pptx")?;
let issues = repair.validate();

println!("Found {} issues", issues.len());
for issue in &issues {
    println!("  - {} (severity: {})", issue.description(), issue.severity());
}

// Repair and save
let result = repair.repair();
if result.is_valid {
    repair.save("repaired.pptx")?;
    println!("File repaired successfully!");
}

Detectable Issues:

• Missing required parts (Content_Types.xml, relationships)
• Invalid or malformed XML
• Broken relationship references
• Missing slide references
• Orphan slides
• Invalid content types

Installation

Add to Cargo.toml:

[dependencies]
ppt-rs = "0.1"

Examples

Tables

use ppt_rs::generator::{SlideContent, TableBuilder, TableRow, TableCell, create_pptx_with_content};

let table = TableBuilder::new(vec![2000000, 2000000])
    .add_simple_row(vec!["Name", "Status"])
    .add_simple_row(vec!["Alice", "Active"])
    .build();

// Styled table with formatting
let styled_table = TableBuilder::new(vec![2000000, 2000000, 2000000])

let conn = Connector::straight(1000000, 1000000, 3000000, 1000000)
    .with_line(ConnectorLine::new("1565C0", 25400))
    .with_end_arrow(ArrowType::Triangle)
    .with_arrow_size(ArrowSize::Large);

// Elbow connector with dashed line
let elbow = Connector::elbow(1000000, 2000000, 3000000, 3000000)
    .with_line(ConnectorLine::new("2E7D32", 19050).with_dash(LineDash::Dash))
