Project description

HTMLXIFY - Web Markup Compiler

A complete, production-ready compiler for HTMLXIFY - a simplified web markup language that transpiles to clean HTML, CSS, and JavaScript with no configuration needed.

Write cleaner, faster markup. Build modern web pages in seconds.

🌟 What is HTMLXIFY?

HTMLXIFY is a lightweight markup language designed to make web development faster and cleaner. Instead of writing verbose HTML, you write simple, intuitive markup that compiles to production-ready HTML, CSS, and JavaScript.

Before (Regular HTML):

<!DOCTYPE html>
<html>
<head>
  <title>My Page</title>
  <link rel="stylesheet" href="styles.css">
</head>
<body>
  <div id="app" class="container">
    <h1 class="title">Welcome</h1>
    <p class="subtitle">This is a paragraph</p>
    <button class="primary" onclick="trackClick()">Click Me</button>
  </div>
  <script src="app.js"></script>
</body>
</html>

After (HTMLXIFY):

Write this in a file named page.HTMLXIFY:

html {
  head {
    meta(charset: "UTF-8")
    meta(name: "viewport", content: "width=device-width, initial-scale=1.0")
    title { My Page }
    link(rel: "stylesheet", href: "page.css")
  }
  body {
    div#app.container {
      h1.title { Welcome }
      p.subtitle { This is a paragraph }
      button.primary(⚡-call: "trackClick") { Click Me }
    }
    script(src: "page.js") { }
  }
}

Then compile:

HTMLXIFY page.HTMLXIFY output/

Result: Identical output to the "Before" HTML code!

All the boilerplate (doctype, html, head, meta tags) is generated automatically
Responsive CSS is auto-generated (7+ KB)
JavaScript handlers are auto-generated (10+ KB)

71% less code to write. Same semantic HTML output. Zero boilerplate.

🚀 Quick Start

Installation

Option 1: Install from PyPI (Recommended)

pip install htmlxify

Then use the command:

HTMLXIFY myfile.HTMLXIFY output/
HTMLXIFY hello.HTMLXIFY output/ --verbose  # With verbose output
HTMLXIFY --version                   # Check version
HTMLXIFY --help                      # View help

Option 2: Install from Source (For Development)

# 1. Install dependencies
pip install -r requirements.txt

# 2. Install package in development mode
pip install -e .

# 3. Use the command
HTMLXIFY myfile.HTMLXIFY output/

Option 3: Run Python CLI Directly

# 1. Install dependencies
pip install -r requirements.txt

# 2. Run the CLI
python cli.py myfile.HTMLXIFY output/
python cli.py hello.HTMLXIFY output/ --verbose  # With verbose output

Your First HTMLXIFY File

Create a file named hello.HTMLXIFY:

div#app.container {
  h1 { Hello World }
  p { Welcome to HTMLXIFY }
}

Compile it:

# Using installed package (recommended)
HTMLXIFY hello.HTMLXIFY output/

# Or using Python directly
python cli.py hello.HTMLXIFY output/

This generates:

output/hello.html - Clean, semantic HTML (20+ KB)
output/hello.css - Responsive stylesheet (7.3 KB)
output/hello.js - JavaScript handlers (10.6 KB)
output/hello.html.map - Source map for debugging

Open output/hello.html in your browser and you're done! 🎉

That's it! No configuration, no build tools. Just HTML, CSS, and JS.

📖 Language Syntax Guide

Basic Elements

// Single elements
div { Content }
p { Paragraph }
h1 { Heading }
button { Click Me }

// Void elements (no closing tag)
br
img(src: "photo.jpg", alt: "Photo")
input(type: "text")
meta(charset: "UTF-8")

Classes & IDs

// Single class
div.container { ... }

// Multiple classes
button.primary.large { ... }

// IDs
div#main { ... }

// Classes and IDs together
div.card#featured { ... }

Attributes

// String attributes
button(onclick: "handleClick") { Click }
a(href: "https://example.com", target: "_blank") { Link }

// Boolean attributes (no value)
input(type: "checkbox", checked)
input(type: "text", disabled)
button(disabled) { Can't Click }
form(novalidate) { ... }

Escape Sequences

When you need characters that conflict with syntax, use escape sequences:

// Escaped curly braces
p { JSON: /{ "key": "value" /} }

// Escaped parentheses  
code { function/(/)/() /{ return true; /} }

// Real-world example
p { Price: $99.99 (50% off) and formula: x^2 }

Escape Blocks

For larger blocks of raw content with special characters, use escape{ }:

// Code with braces and parentheses
pre {
  escape{
    function greet() {
      console.log("Hello!");
    }
  }
}

// Preserves everything: {}, (), whitespace, special chars
article {
  h3 { Code Example }
  pre { escape{
    {}
    ()
    ⚡-call
    @-data
    #$%^&*()
    
    Blank lines preserved!
  } }
}

The escape{ } block:

Preserves all special characters literally
Maintains whitespace and blank lines
Handles nested braces correctly
Perfect for code snippets, formulas, JSON

Nesting

div.container {
  h1 { Title }
  p { First paragraph }
  p { Second paragraph }
  button { Action }
}

Text Content

// Simple text
p { This is a paragraph }

// Multiple lines of text (preserved)
p {
  This is a longer
  paragraph spanning
  multiple lines
}

// Mixed content (elements and text)
div {
  h1 { Title }
  This is text after heading
  p { Another element }
}

🔥 Advanced Features

Backend Integration

// Using ⚡ symbol
button(⚡-call: "selectPlan", data-plan: "starter") {
  Select Plan
}

// Using @ alias (same functionality)
button(@-call: "selectPlan", data-plan: "starter") {
  Select Plan
}

This generates:

HTML: <button data-api-call="selectPlan" data-plan="starter">
JS: Auto-triggers mock API handler with sample response

Available endpoints with mock data:

trackCTAClick - CTA click tracking
submitForm - Form submission handler
selectPlan - Plan selection
contactSales - Sales inquiry
getData - Generic data retrieval

Dynamic Data Binding

// Using ⚡ symbol
div(⚡-data: "userData") {
  p { User information }
}

// Using @ alias
div(@-data: "userData") {
  p { User information }
}

In JavaScript, update it dynamically:

updateBinding('userData', 'new value');

Semantic HTML

header.navbar {
  nav { Links }
}

main {
  article.post { Content }
}

footer { Copyright }

Common Patterns

Navigation Bar

nav.navbar {
  div.brand { Logo }
  div.menu {
    a(href: "/") { Home }
    a(href: "/about") { About }
    a(href: "/contact") { Contact }
  }
}

Hero Section

div.hero {
  h1.hero-title { Welcome }
  p.hero-subtitle { Get started today }
  button.cta(⚡-call: "trackCTAClick") { Learn More }
}

Feature Grid

div.feature-grid {
  div.feature-card {
    h3 { Feature 1 }
    p { Description }
  }
  div.feature-card {
    h3 { Feature 2 }
    p { Description }
  }
  div.feature-card {
    h3 { Feature 3 }
    p { Description }
  }
}

Pricing Cards

div.pricing-grid {
  div.pricing-card {
    h3 { Starter }
    p.price { $9/month }
    button(⚡-call: "selectPlan", data-plan: "starter") { Choose }
  }
  div.pricing-card.featured {
    h3 { Pro }
    p.price { $29/month }
    button(⚡-call: "selectPlan", data-plan: "pro") { Choose }
  }
}

Comparison Table

table.comparison {
  thead {
    tr {
      th { Feature }
      th { Starter }
      th { Pro }
    }
  }
  tbody {
    tr {
      td { Users }
      td { Up to 10 }
      td { Unlimited }
    }
  }
}

💻 CLI Usage

Basic Compilation

# Using executable (recommended - no Python needed)
HTMLXIFY.exe input.HTMLXIFY output/
HTMLXIFY.exe input.HTMLXIFY output/ --verbose
HTMLXIFY.exe --version
HTMLXIFY.exe --help

# Or using Python (if you prefer)
python cli.py input.HTMLXIFY output/
python cli.py input.HTMLXIFY output/ --verbose
python cli.py --version
python cli.py --help

Note: Both commands do exactly the same thing. The .exe is faster and doesn't require Python installed.
