# FolderWeb Documentation

Welcome to FolderWeb—a minimal PHP framework that turns your folder structure into a website. No build steps, no databases, no complexity. Just files, folders, and modern web standards.

## What is FolderWeb?

FolderWeb is a file-based content management system that:

- **Uses your folder structure as URL structure** — Drop files in folders, get pages
- **Works without JavaScript** — Pure PHP and modern CSS
- **Requires no build process** — Edit, save, refresh. Done.
- **Supports multiple languages** — Built-in i18n with URL-based language switching
- **Stays maintainable** — Code designed to last years or decades

Perfect for blogs, documentation sites, portfolios, and small business websites where simplicity and longevity matter.

## Core Concepts

### File-Based Routing

Your folder structure **is** your URL structure:

```
content/
├── about.md              → /about/
├── blog/
│   ├── index.md          → /blog/
│   └── first-post/
│       └── index.md      → /blog/first-post/
└── contact.html          → /contact/
```

No configuration, no route definitions—just create folders and files.

### Content Types

FolderWeb supports three content types:

- **Markdown (`.md`)** — Write in Markdown, get HTML
- **HTML (`.html`)** — Static HTML content
- **PHP (`.php`)** — Dynamic content with PHP

Mix and match as needed. All three can coexist in the same directory.

### Template System

Templates control how content is presented:

- **Base template** — HTML scaffold (header, nav, footer)
- **Page template** — Wraps single-page content
- **List template** — Displays collections (blogs, portfolios)

Override defaults by creating `custom/templates/`.

### Metadata Files

Configure pages with `metadata.ini` files:

```ini
title = "My Page"
summary = "Short description"
date = "2024-12-15"
slug = "custom-url"
menu = 1
```

Control titles, URLs, navigation, templates, and more.

### Plugin System

Extend functionality with a simple hook system:

```php
Hooks::add(Hook::TEMPLATE_VARS, function(array $vars, Context $ctx) {
    $vars['customVariable'] = 'value';
    return $vars;
});
```

Three hooks provide extensibility without complexity.

## Philosophy

FolderWeb follows these principles:

### Minimalism

Use only what's strictly necessary. No frameworks, no build tools, no package managers for frontend code. If it doesn't provide clear, lasting value, it doesn't belong.

### Longevity

Code should be readable and maintainable for years or decades. Avoid rapidly changing components and dependencies. Favor web standards over abstractions.

### Simplicity

HTML, PHP, and CSS. That's it. No preprocessing, no transpiling, no complex build pipelines. Edit a file, refresh the browser, see the result.

### Performance

Fast page loads, minimal HTTP requests, no JavaScript parsing delay. Performance metrics displayed in the footer—transparency and pride.
