- Markdown processing with frontmatter support
- Template rendering with Handlebars
- HTML generation with minification
- Asset management and optimisation

- **Performance Optimised**
- Parallel processing capabilities
- Efficient memory usage
- Content caching
- Minimal dependencies

- **Developer Experience**
- Intuitive CLI interface
- Rich error messages
- Extensive documentation
- Type-safe configurations

## Installation

Add `nucleusflow` to your `Cargo.toml`:

```toml
[dependencies]
nucleusflow = "0.0.1"
```

## Usage

Here's a basic example of how to use `nucleusflow`:

```rust,no_run
use nucleusflow::{NucleusFlow, NucleusFlowConfig, FileContentProcessor, HtmlOutputGenerator, HtmlTemplateRenderer};
use std::path::PathBuf;

// Create configuration
let config = NucleusFlowConfig::new(
"content",
"public",
"templates"
).expect("Failed to create config");

// Initialize processors with the concrete implementations
let content_processor = FileContentProcessor::new(PathBuf::from("content"));
let template_renderer = HtmlTemplateRenderer::new(PathBuf::from("templates"));
let output_generator = HtmlOutputGenerator::new(PathBuf::from("public"));

// Create NucleusFlow instance
let nucleus = NucleusFlow::new(
config,
Box::new(content_processor),
Box::new(template_renderer),
Box::new(output_generator)
);

// Process content
nucleus.process().expect("Failed to process content");
```

### CLI Usage

```bash
# Create a new site
nucleusflow new my-site --template blog

# Build the site
nucleusflow build --content content/ --output public/

```

This example demonstrates setting up NucleusFlow with a Markdown processor, Handlebars templating, and HTML output generation.
