# Markdown Server Implementation Summary
|
||||||
|
|
||||||
|
## Overview
|
||||||
|
|
||||||
|
Successfully implemented a Rust-based web server that serves Markdown files from a `./content` directory as HTML, with the following key features:
|
||||||
|
|
||||||
|
## Key Features Implemented
|
||||||
|
|
||||||
|
### 1. **Flexible Path Resolution** ✅
|
||||||
|
- Any URL path maps to `./content/{path}.md`
|
||||||
|
- Examples:
|
||||||
|
- `/foo/bar` → `./content/foo/bar.md`
|
||||||
|
- `/zap/zap` → `./content/zap/zap.md`
|
||||||
|
- `/any/deep/nested/path` → `./content/any/deep/nested/path.md`
|
||||||
|
- `/` → `./content/index.md`
|
||||||
|
|
||||||
|
### 2. **Runtime Configuration** ✅
|
||||||
|
- **Working Directory**: `--workdir` flag to specify where the `./content` folder is located
|
||||||
|
- **Port Configuration**: `--port` flag to change the listening port
|
||||||
|
- **Host Configuration**: `--host` flag to change the binding host
|
||||||
|
|
||||||
|
### 3. **Markdown Processing** ✅
|
||||||
|
- Uses `pulldown-cmark` for fast and reliable Markdown to HTML conversion
|
||||||
|
- Includes basic CSS styling for readable output
|
||||||
|
- Supports code blocks, headers, lists, and all standard Markdown features
|
||||||
|
|
||||||
|
### 4. **Error Handling** ✅
|
||||||
|
- Returns 404 for non-existent files
|
||||||
|
- Prevents directory traversal attacks
|
||||||
|
- Gracefully handles missing content directory
|
||||||
|
|
||||||
|
### 5. **User Experience** ✅
|
||||||
|
- Shows available content on startup
|
||||||
|
- Clear command line interface with help documentation
|
||||||
|
- Automatic content directory creation
|
||||||
|
|
||||||
|

||||||
|
pulldown-cmark = "0.10" # Markdown parser
|
||||||
|
clap = "4.0" # Command line argument parsing
|
||||||
|
walkdir = "2.0" # Directory traversal
|
||||||
|
```
|
||||||
|
|
||||||
|

# Markdown Server
|
||||||
|
|
||||||
|
A Rust-based web server that serves Markdown files from a `./content` directory as HTML. The URL path corresponds to the file path within the content directory.
|
||||||
|
|
||||||
|
## Features
|
||||||
|
|
||||||
|
- **Automatic Markdown to HTML conversion** - Uses `pulldown-cmark` for fast Markdown parsing
|
||||||
|
- **Flexible path resolution** - Any URL path maps to `./content/{path}.md`
|
||||||
|
- **Configurable working directory** - Specify where the `./content` folder is located
|
||||||
|
- **Customizable host and port** - Run on any interface and port
|
||||||
|
- **Automatic content discovery** - Shows available content on startup
|
||||||
|
|
||||||
|
## Installation
|
||||||
|
|
||||||
|
```bash
|
||||||
|
cargo build --release
|
||||||
|
```
|
||||||
|
|
||||||
|
## Usage
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Default usage (current directory, port 8080)
|
||||||
|
./target/release/mhmmcontent
|
||||||
|
|
||||||
|
# Custom working directory
|
||||||
|
./target/release/mhmmcontent --workdir /path/to/your/content
|
||||||
|
|
||||||
|
# Custom port
|
||||||
|
./target/release/mhmmcontent --port 9090
|
||||||
|
|
||||||
|
# Custom host and port
|
||||||
|
./target/release/mhmmcontent --host 0.0.0.0 --port 8888
|
||||||
|
|
||||||
|
# All options
|
||||||
|
./target/release/mhmmcontent --workdir /path/to/content --host 0.0.0.0 --port 9090
|
||||||
|
```
|
||||||
|
|
||||||
|
## How It Works
|
||||||
|
|
||||||
|
1. **Directory Structure**: Place your Markdown files in a `./content` directory
|
||||||
|
2. **URL Mapping**: The server maps URL paths directly to file paths:
|
||||||
|
- `http://localhost:8080/foo/bar` → `./content/foo/bar.md`
|
||||||
|
- `http://localhost:8080/zap/zap` → `./content/zap/zap.md`
|
||||||
|
- `http://localhost:8080/` → `./content/index.md`
|
||||||
|
|
||||||
|
3. **Markdown Processing**: Files are converted to HTML with proper styling
|
||||||
|
|
||||||
|
## Example
|
||||||
|
|
||||||
|
Given this directory structure:
|
||||||
|
```
|
||||||
|
content/
|
||||||
|
├── index.md
|
||||||
|
├── foo/
|
||||||
|
│ └── bar.md
|
||||||
|
└── zap/
|
||||||
|
└── zap.md
|
||||||
|
```
|
||||||
|
|
||||||
|
The server will serve:
|
||||||
|
- `http://localhost:8080/` → `content/index.md`
|
||||||
|
- `http://localhost:8080/foo/bar` → `content/foo/bar.md`
|
||||||
|
- `http://localhost:8080/zap/zap` → `content/zap/zap.md`
|
||||||
|
|
||||||
|
## Command Line Options
|
||||||
|
|
||||||
|
```
|
||||||
|
Options:
|
||||||
|
-w, --workdir <WORKDIR> Working directory containing the ./content folder [default: .]
|
||||||
|
-p, --port <PORT> Port to bind the server to [default: 8080]
|
||||||
|
--host <HOST> Host to bind the server to [default: 127.0.0.1]
|
||||||
|
-t, --template <TEMPLATE> Template/layout name to use (default: "default") [default: default]
|
||||||
|
-h, --help Print help
|
||||||
|
-V, --version Print version
|
||||||
|
```
|
||||||
|
|
||||||
|
## Templates
|
||||||
|
|
||||||
|
The server supports custom templates/layouts using Handlebars syntax. Templates are loaded from the `./layout` directory in the working directory.
|
||||||
|
|
||||||
|
### Template Features
|
||||||
|
|
||||||
|
- **Custom Layouts**: Create your own HTML layouts with `{{title}}`, `{{content}}`, and `{{path}}` variables
|
||||||
|
- **Handlebars Syntax**: Full support for Handlebars templating
|
||||||
|
- **Fallback**: If a template doesn't exist, the server uses a built-in default template
|
||||||
|
- **Multiple Templates**: Create different templates for different use cases
|
||||||
|
|
||||||
|
### Template Variables
|
||||||
|
|
||||||
|
- `{{title}}` - The title of the page (from the Markdown filename)
|
||||||
|
- `{{content}}` - The rendered HTML content from the Markdown file
|
||||||
|
- `{{path}}` - The URL path of the current page
|
||||||
|
|
||||||
|
### Example Template Structure
|
||||||
|
|
||||||
|
```
|
||||||
|
layout/
|
||||||
|
├── default.hbs # Default template
|
||||||
|
├── minimal.hbs # Minimal template
|
||||||
|
└── custom.hbs # Custom template
|
||||||
|
```
|
||||||
|
|
||||||
|
### Creating a Custom Template
|
||||||
|
|
||||||
|
1. Create a `layout` directory in your working directory
|
||||||
|
2. Create a template file with `.hbs` extension (e.g., `my-template.hbs`)
|
||||||
|
3. Use Handlebars syntax with the available variables
|
||||||
|
4. Run the server with `--template my-template`
|
||||||
|
|
||||||
|
**Note**: The server now **requires** template files to exist. If you specify a template that doesn't exist, the server will fail with a clear error message indicating which template file is missing.
|
||||||
|
|
||||||
|
### Example Template
|
||||||
|
|
||||||
|
```html
|
||||||
|
<!DOCTYPE html>
|
||||||
|
<html>
|
||||||
|
<head>
|
||||||
|
<title>{{title}}</title>
|
||||||
|
<style>
|
||||||
|
body {
|
||||||
|
font-family: Arial, sans-serif;
|
||||||
|
max-width: 800px;
|
||||||
|
margin: 0 auto;
|
||||||
|
padding: 20px;
|
||||||
|
}
|
||||||
|
</style>
|
||||||
|
</head>
|
||||||
|
<body>
|
||||||
|
<header>
|
||||||
|
<h1>My Custom Site</h1>
|
||||||
|
<nav>
|
||||||
|
<a href="/">Home</a> |
|
||||||
|
<a href="/about">About</a>
|
||||||
|
</nav>
|
||||||
|
</header>
|
||||||

|
||||||
|
<p>© 2023 My Site</p>
|
||||||
|
</footer>
|
||||||
|
</body>
|
||||||
|
</html>
|
||||||
|
```
|
||||||
|
|
||||||
|
### Using Templates
|
||||||

# Template/Layout Feature Implementation
|
||||||
|
|
||||||
|
## Overview
|
||||||
|
|
||||||
|
Successfully implemented a flexible template/layout system that allows loading custom HTML templates from the working directory's `./layout` folder.
|
||||||
|
|
||||||
|
## Key Features
|
||||||
|
|
||||||
|
### ✅ **Template Loading from Filesystem**
|
||||||
|
- **Custom Template Support**: Loads templates from `./layout/{template_name}.hbs`
|
||||||
|
- **Handlebars Integration**: Uses the `handlebars` crate for powerful templating
|
||||||
|
- **Fallback Mechanism**: Gracefully falls back to built-in default template if custom template not found
|
||||||
|
- **Runtime Configuration**: Template name configurable via `--template` flag (default: "default")
|
||||||
|
|
||||||
|
### ✅ **Template Variables**
|
||||||
|
- `{{title}}` - Page title derived from Markdown filename
|
||||||
|
- `{{content}}` - Rendered HTML content from Markdown
|
||||||
|
- `{{path}}` - Current URL path
|
||||||
|
|
||||||
|
### ✅ **Error Handling**
|
||||||
|
- **File Not Found**: Falls back to built-in template if custom template doesn't exist
|
||||||
|
- **Parse Errors**: Falls back to simple HTML if template rendering fails
|
||||||
|
- **Directory Creation**: Automatically handles missing layout directories
|
||||||
|
|
||||||
|
### ✅ **User Experience**
|
||||||
|
- **Clear Logging**: Shows which template is being used on startup
|
||||||
|
- **Help Documentation**: Updated `--help` shows template option
|
||||||
|
- **Flexible Configuration**: Easy to switch between different templates
|
||||||
|
|
||||||
|
## Implementation Details
|
||||||
|
|
||||||
|
### Template Loading Logic
|
||||||
|
|
||||||
|
```rust
|
||||||
|
fn load_template(workdir: &PathBuf, template_name: &str) -> Handlebars<'static> {
|
||||||
|
// 1. Try to load from ./layout/{template_name}.hbs
|
||||||
|
// 2. If found and valid, use it
|
||||||
|
// 3. Otherwise, use built-in default template
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### Template Rendering
|
||||||
|
|
||||||
|
```rust
|
||||||
|
let template_data = json!({
|
||||||
|
"title": title,
|
||||||
|
"content": html_output,
|
||||||
|
"path": path.into_inner(),
|
||||||
|
});
|
||||||
|
|
||||||
|
match data.template_engine.render("layout", &template_data) {
|
||||||
|
Ok(rendered) => /* Use rendered template */,
|
||||||
|
Err(_) => /* Fallback to simple HTML */
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
## File Structure
|
||||||
|
|
||||||
|
```
|
||||||
|
mhmmcontent/
|
||||||
|
├── layout/ # Template directory
|
||||||
|
│ ├── default.hbs # Custom default template
|
||||||
|
│ ├── minimal.hbs # Minimal template example
|
||||||
|
│ └── *.hbs # Additional custom templates
|
||||||
|
├── content/ # Markdown content
|
||||||
|
│ └── *.md # Markdown files
|
||||||
|
└── src/main.rs # Server implementation
|
||||||
|
```
|
||||||
|
|
||||||
|
## Usage Examples
|
||||||
|
|
||||||
|
### Default Template (Built-in)
|
||||||
|
```bash
|
||||||
|
./mhmmcontent
|
||||||
|
# Uses built-in default template
|
||||||
|
```
|
||||||
|
|
||||||
|
### Custom Template from Filesystem
|
||||||
|
```bash
|
||||||
|
./mhmmcontent --template default
|
||||||
|
# Loads from ./layout/default.hbs if it exists
|
||||||
|
```
|
||||||
|
|
||||||
|
### Different Custom Template
|
||||||
|
```bash
|
||||||
|
./mhmmcontent --template minimal
|
||||||
|
# Loads from ./layout/minimal.hbs
|
||||||
|
```
|
||||||
|
|
||||||
|
### Non-existent Template (Error)
|
||||||
|
```bash
|
||||||
|
./mhmmcontent --template nonexistent
|
||||||
|
# Fails with clear error message indicating missing template file
|
||||||
|
```
|
||||||
|
|
||||||
|
## Template Examples
|
||||||
|
|
||||||
|
### Basic Template (`layout/basic.hbs`)
|
||||||
|
```html
|
||||||
|
<!DOCTYPE html>
|
||||||
|
<html>
|
||||||
|
<head>
|
||||||
|
<title>{{title}}</title>
|
||||||
|
<style>
|
||||||
|
body { font-family: Arial, sans-serif; max-width: 800px; margin: 0 auto; padding: 20px; }
|
||||||
|
pre { background: #f0f0f0; padding: 10px; overflow-x: auto; }
|
||||||
|
</style>
|
||||||
|
</head>
|
||||||
|
<body>
|
||||||
|
<h1>{{title}}</h1>
|
||||||
|
<div>{{{content}}}</div>
|
||||||
|
<footer><small>Path: {{path}}</small></footer>
|
||||||
|
</body>
|
||||||
|
</html>
|
||||||
|
```
|
||||||
|
|
||||||
|
### Advanced Template (`layout/advanced.hbs`)
|
||||||
|
```html
|
||||||
|

## Benefits
|
||||||
|
|
||||||
|
### For Users
|
||||||
|
- **Custom Branding**: Easy to add logos, colors, and branding
|
||||||
|
- **Consistent Layout**: Maintain consistent header/footer across all pages
|
||||||
|
- **Navigation**: Add navigation menus to all pages automatically
|
||||||
|
- **Responsive Design**: Create mobile-friendly layouts
|
||||||
|
|
||||||
|
### For Developers
|
||||||
|
- **Separation of Concerns**: Content (Markdown) separate from presentation (HTML)
|
||||||
|
- **Easy Customization**: No need to modify server code to change appearance
|
||||||
|
- **Multiple Themes**: Support different templates for different use cases
|
||||||
|
- **Fallback Safety**: Server continues to work even if templates are missing
|
||||||
|
|
||||||
|
## Technical Implementation
|
||||||
|
|
||||||
|
### Dependencies Added
|
||||||
|
```toml
|
||||||
|
[dependencies]
|
||||||
|
handlebars = "4.0" # Templating engine
|
||||||
|
```
|
||||||
|
|
||||||
|
### Key Functions
|
||||||
|
- `load_template()`: Loads and registers templates
|
||||||
|
- `serve_markdown()`: Renders content using templates
|
||||||
|
- Template fallback mechanism for robustness
|
||||||
|
|
||||||
|
### Error Handling
|
||||||
|
- **File system errors**: Clear error messages for missing template files
|
||||||
|
- **Template parsing errors**: Detailed error messages for invalid template syntax
|
||||||
|
- **Rendering errors**: Fallback to simple HTML if template rendering fails
|
||||||
|
- **Strict Requirements**: Server fails fast if required template is missing
|
||||||
|
|
||||||
|
## Performance
|
||||||
|
|
||||||
|
- **Fast Template Loading**: Templates loaded once at startup
|
||||||
|
- **Efficient Rendering**: Handlebars provides fast template rendering
|
||||||
|
- **Minimal Overhead**: Template processing adds negligible latency
|
||||||
|
- **Memory Efficient**: Templates stored in memory after initial load
|
||||||
|
|
||||||
|
The template feature makes the Markdown server highly customizable while maintaining robustness and ease of use.

# Deep Nested Path
|
||||||
|
|
||||||
|
This demonstrates that the server can handle deeply nested paths.
|
||||||
|
|
||||||
|
The URL `/any/deep/nested/path` maps to this file.

# Hello World
|
||||||
|
|
||||||
|
This is a sample markdown file served at `/foo/bar`.
|
||||||
|
|
||||||
|
## Features
|
||||||
|
|
||||||
|
- Markdown support
|
||||||
|
- Automatic HTML conversion
|
||||||
|
- URL path based on file location
|
||||||
|
|
||||||
|
```rust
|
||||||
|
fn main() {
|
||||||
|
println!("Hello from Rust!");
|
||||||
|
}
|

# Welcome to Markdown Server
|
||||||
|
|
||||||
|
This is the home page served at `/`.
|
||||||
|
|
||||||
|
## Available Pages
|
||||||
|
|
||||||
|
- [/foo/bar](foo/bar) - Sample page
|
||||||
|
- [/zap/zap](zap/zap) - Another test page
|
||||||
|
- [/any/deep/nested/path](any/deep/nested/path) - Deep nesting example
|
||||||
|
|
||||||
|
## How it works
|
||||||
|
|
||||||
|
The server automatically:
|
||||||
|
1. Takes the URL path
|
||||||
|
2. Looks for a corresponding `.md` file in the `./content` directory
|
||||||
|
3. Converts Markdown to HTML
|
||||||
|
4. Serves the result

# Zap Zap Page
|
||||||
|
|
||||||
|
This is the zap/zap page served at `/zap/zap`.
|
||||||
|
|
||||||
|
## Testing
|
||||||
|
|
||||||
|
The server should resolve any path to the corresponding `.md` file in the content directory.
|
||||||
|
|
||||||
|
- Path: `/zap/zap` → File: `./content/zap/zap.md`
|
||||||
|
- Path: `/foo/bar` → File: `./content/foo/bar.md`
|
||||||
|
- Path: `/any/deep/nested/path` → File: `./content/any/deep/nested/path.md`
