description	Create and deliver terminal-based presentations from markdown files with themes, code execution, mermaid/d2 diagrams, LaTeX/typst formulas, and PDF/HTML export capabilities.

presenterm - Terminal Slideshow Tool

presenterm is a modern terminal-based presentation tool that renders markdown files as slides. It supports themes, code syntax highlighting, images, diagram rendering (mermaid, d2), mathematical formulas (LaTeX, typst), and can export to PDF or HTML.

Core Principles

Markdown-first: Write presentations in familiar markdown syntax
Terminal-native: Runs entirely in the terminal with rich rendering
Advanced rendering: Render mermaid/d2 diagrams and LaTeX/typst formulas as images
Presentation mode: Separate presentation view with speaker notes support
Export capabilities: Generate PDF or HTML from markdown slides
Code execution: Execute code snippets during presentations
Theme support: Multiple built-in themes and custom theme support

Installation

# macOS (Homebrew)
brew install presenterm

# Cargo
cargo install presenterm

# From source
git clone https://github.com/mfontanini/presenterm
cd presenterm
cargo install --path .

Basic Usage

Running Presentations

# Run a presentation
presenterm presentation.md

# Use presentation mode (full-screen, controls hidden)
presenterm -p presentation.md
presenterm --present presentation.md

# Use specific theme
presenterm -t dark presentation.md
presenterm --theme catppuccin presentation.md

# List available themes
presenterm --list-themes

# Show current theme
presenterm --current-theme

Exporting

# Export to PDF
presenterm -e presentation.md
presenterm --export-pdf presentation.md

# Export to PDF with specific output path
presenterm -e presentation.md -o output.pdf
presenterm --export-pdf presentation.md --output slides.pdf

# Export to HTML
presenterm -E presentation.md
presenterm --export-html presentation.md -o presentation.html

# Specify temporary path for export
presenterm -e presentation.md --export-temporary-path /tmp/presenterm

Code Highlighting

# Syntax Highlighting

```python
def fibonacci(n):
    if n <= 1:
        return n
    return fibonacci(n-1) + fibonacci(n-2)
```

```rust
fn factorial(n: u64) -> u64 {
    (1..=n).product()
}
```

```javascript
const greet = (name) => {
    console.log(`Hello, ${name}!`);
};
```

Code Execution

Executable Code Blocks

# Enable code snippet execution
presenterm -x presentation.md
presenterm --enable-snippet-execution presentation.md

# Enable auto-execution with replacement
presenterm -X presentation.md
presenterm --enable-snippet-execution-replace presentation.md

# Validate snippets without running
presenterm --validate-snippets presentation.md

Executable Code Syntax

# Live Demo

```bash +exec
echo "This will execute when you advance to this slide"
date
```

---

# Auto-Replace Demo

```bash +exec_replace
ls -la
```

<!-- The output will replace the code block -->

Advanced Rendering

presenterm supports rendering diagrams and formulas directly from code blocks, converting them to images during presentation load.

Mermaid Diagrams

Render mermaid diagrams using the +render attribute.

Requirements:

Install mermaid-cli: npm install -g @mermaid-js/mermaid-cli

Syntax:

```mermaid +render
sequenceDiagram
    Alice->>Bob: Hello Bob, how are you?
    Bob-->>Alice: I'm good thanks!
    Alice-)Bob: See you later!
```

```mermaid +render
graph TD
    A[Start] --> B{Is it working?}
    B -->|Yes| C[Great!]
    B -->|No| D[Debug]
    D --> B
```

```mermaid +render
pie title Project Time Distribution
    "Development" : 40
    "Testing" : 25
    "Documentation" : 20
    "Meetings" : 15
```

Configuration (in config.yaml):

mermaid:
  # Theme selection
  theme: dark
  # Background color
  background: "#2E3440"
  # Image scaling
  scale: 2.0

Size control with width attribute:

```mermaid +render +width:80%
graph LR
    A --> B --> C
```

Performance Note:

Rendering takes ~2 seconds per diagram
Rendered asynchronously (default 2 threads)

d2 Diagrams

Render d2 diagrams for architecture and system diagrams.

Requirements:

Install d2: brew install d2 or download from releases

Syntax:

```d2 +render
# System Architecture
web_server: Web Server {
  shape: rectangle
}
database: Database {
  shape: cylinder
}
cache: Redis Cache {
  shape: stored_data
}

web_server -> database: queries
web_server -> cache: reads/writes
```

```d2 +render
my_table: {
  shape: sql_table
  id: int {constraint: primary_key}
  username: varchar(255)
  email: varchar(255)
  created_at: timestamp
}
```

```d2 +render
direction: right

users -> api: HTTP requests
api -> auth: validate token
api -> database: query data
api -> cache: check cache
```

Configuration (in config.yaml):

d2:
  # Theme selection
  theme: "Nord"
  # Image scaling
  scale: 1.5

Size control:

```d2 +render +width:70%
A -> B -> C
```

LaTeX Formulas

Render LaTeX mathematical formulas as images.

Requirements:

Install typst: brew install typst or cargo install typst-cli
Install pandoc: brew install pandoc

How it works:

Pandoc converts LaTeX to typst
Typst renders the formula to an image

Syntax:

```latex +render
\[ \sum_{n=1}^{\infty} 2^{-n} = 1 \]
```

```latex +render
\[
E = mc^2
\]
```

```latex +render
\[
\int_{-\infty}^{\infty} e^{-x^2} dx = \sqrt{\pi}
\]
```

```latex +render
\[
\frac{d}{dx}\left( \int_{a}^{x} f(u)\,du\right) = f(x)
\]
```

```latex +render
\[
\begin{bmatrix}
a & b \\
c & d
\end{bmatrix}
\]
```

Configuration (in config.yaml):

# Pixels per inch for formula rendering
typst:
  ppi: 300

Size control:

```latex +render +width:60%
\[ \oint_C \mathbf{F} \cdot d\mathbf{r} = \iint_S (\nabla \times \mathbf{F}) \cdot d\mathbf{S} \]
```

Typst Formulas

Render typst formulas directly (bypassing LaTeX conversion).

Requirements:

Install typst: brew install typst

Syntax:

```typst +render
$ sum_(n=1)^oo 1/n^2 = pi^2/6 $
```

```typst +render
$ integral_(-oo)^oo e^(-x^2) d x = sqrt(pi) $
```

```typst +render
$ mat(
  1, 2;
  3, 4;
) $
```

Benefits over LaTeX:

Faster (no pandoc conversion step)
Native typst syntax
More modern formula typesetting

Rendering Configuration

Global config.yaml settings:

# Formula rendering
typst:
  ppi: 300  # Pixels per inch for formulas

# Mermaid diagrams
mermaid:
  theme: dark
  background: "#2E3440"
  scale: 2.0

# d2 diagrams
d2:
  theme: "Nord"
  scale: 1.5

Complete Rendering Example

# System Architecture

```d2 +render +width:80%
users: Users {
  shape: person
}
lb: Load Balancer {
  shape: rectangle
}
api: API Servers {
  shape: rectangle
}
db: Database {
  shape: cylinder
}

users -> lb
lb -> api: distribute
api -> db: query
```

---

# Request Flow

```mermaid +render
sequenceDiagram
    participant U as User
    participant A as API
    participant D as Database
    participant C as Cache

    U->>A: Request data
    A->>C: Check cache
    alt Cache hit
        C-->>A: Return cached data
    else Cache miss
        A->>D: Query database
        D-->>A: Return data
        A->>C: Update cache
    end
    A-->>U: Response
```

---

# Algorithm Complexity

```latex +render
\[
T(n) = \begin{cases}
O(1) & \text{best case} \\
O(\log n) & \text{average case} \\
O(n) & \text{worst case}
\end{cases}
\]
```

---

# Mathematical Formula

```typst +render
$ P(A|B) = (P(B|A) dot P(A)) / P(B) $
```

Image Protocols

# Auto-detect best protocol
presenterm --image-protocol auto presentation.md

# Use iTerm2 protocol
presenterm --image-protocol iterm2 presentation.md

# Use kitty protocol (local mode)
presenterm --image-protocol kitty-local presentation.md

# Use kitty protocol (remote mode)
presenterm --image-protocol kitty-remote presentation.md

# Use sixel protocol
presenterm --image-protocol sixel presentation.md

# Use ASCII blocks (fallback)
presenterm --image-protocol ascii-blocks presentation.md
