# Ruby2html 🔮✨
Transform your view logic into elegant, semantic HTML with the power of pure Ruby! 🚀✨
## 🌟 What is Ruby2html?
Ruby2html is a magical gem that allows you to write your views in pure Ruby and automatically converts them into clean, well-formatted HTML. Say goodbye to messy ERB templates and hello to the full power of Ruby in your views! 🎉
## 🚀 Installation
Add this line to your application's Gemfile:
```ruby
gem 'ruby2html'
```
And then execute:
$ bundle install
Or install it yourself as:
$ gem install ruby2html
## 🎨 Usage
### In your ApplicationController
File: `app/controllers/application_controller.rb`
```ruby
# frozen_string_literal: true
class ApplicationController < ActionController::Base
include Ruby2html::RailsHelper
end
```
### In your views
File: `app/views/your_view.html.rb`
```ruby
div class: 'container' do
h1 'Welcome to Ruby2html! 🎉', class: 'main-title', 'data-controller': 'welcome'
link_to 'Home Sweet Home 🏠', root_path, class: 'btn btn-primary', 'data-turbo': false
@items.each do |item|
h2 class: 'item-title', id: "item-#{item[:id]}" do
item[:title]
end
p class: 'item-description' do
item[:description]
end
end
end
plain '
Inline html
'.html_safe
render partial: 'shared/navbar'
```
#### Or use your current .erb views
File: `app/views/your_view.html.erb`
Replace your ERB with beautiful Ruby code:
```erb
<%=
html(self) do
h1 "Welcome to Ruby2html! 🎉", class: 'main-title', 'data-controller': 'welcome'
div id: 'content', class: 'container' do
link_to 'Home Sweet Home 🏠', root_path, class: 'btn btn-primary', 'data-turbo': false
end
@items.each do |item|
h2 class: 'item-title', id: "item-#{item[:id]}" do
item[:title]
end
p class: 'item-description' do
item[:description]
end
end
plain "Inline html
".html_safe
render partial: 'shared/navbar'
end
%>
```

### With ViewComponents
Ruby2html seamlessly integrates with ViewComponents, offering flexibility in how you define your component's HTML structure. You can use the `call` method with Ruby2html syntax, or stick with traditional `.erb` template files.
File: `app/components/application_component.rb`
```ruby
# frozen_string_literal: true
class ApplicationComponent < ViewComponent::Base
include Ruby2html::ComponentHelper
end
```
#### Option 1: Using `call` method with Ruby2html
File: `app/components/greeting_component.rb`
```ruby
# frozen_string_literal: true
class GreetingComponent < ApplicationComponent
def initialize(name)
@name = name
end
def call
html(self) do
h1 class: 'greeting', 'data-user': @name do
"Hello, #{@name}! 👋"
end
p class: 'welcome-message' do
'Welcome to the wonderful world of Ruby2html!'
end
end
end
end
```
#### Option 2: Using traditional ERB template
File: `app/components/farewell_component.rb`
```ruby
# frozen_string_literal: true
class FarewellComponent < ApplicationComponent
def initialize(name)
@name = name
end
end
```
File: `app/components/farewell_component.html.erb`
```erb
Goodbye, <%= @name %>! 👋
We hope you enjoyed using Ruby2html!
<%=
html do
link_to 'Home', root_path, class: 'btn btn-primary', 'data-turbo': false
end
%>
```
This flexibility allows you to:
- Use Ruby2html syntax for new components or when refactoring existing ones
- Keep using familiar ERB templates where preferred
- Mix and match approaches within your application as needed
### More Component Examples
File: `app/components/first_component.rb`
```ruby
# frozen_string_literal: true
class FirstComponent < ApplicationComponent
def initialize
@item = 'Hello, World!'
end
def call
html(self) do
h1 id: 'first-component-title' do
'first component'
end
div class: 'content-wrapper' do
h2 'A subheading'
end
p class: 'greeting-text', 'data-testid': 'greeting' do
@item
end
end
end
end
```
File: `app/components/second_component.rb`
```ruby
# frozen_string_literal: true
class SecondComponent < ApplicationComponent
def call
html(self) do
h1 class: 'my-class', id: 'second-component-title', 'data-controller': 'second' do
'second component'
end
link_to 'Home', root_path, class: 'nav-link', 'data-turbo-frame': false
end
end
end
```
## Without Rails
```ruby
renderer = Ruby2html::Render.new(nil) do # nil is the context, you can use self or any other object
html do
head do
title 'Ruby2html Example'
end
body do
h1 'Hello, World!'
end
end
end
puts renderer.render # => "Ruby2html ExampleHello, World!
"
```
## 🐢 Gradual Adoption
One of the best features of Ruby2html is that you don't need to rewrite all your views at once! You can adopt it gradually, mixing Ruby2html with your existing ERB templates. This allows for a smooth transition at your own pace.
### Mixed usage example
File: `app/views/your_mixed_view.html.erb`
```erb
Welcome to our gradually evolving page!
<%= render partial: 'legacy_erb_partial' %>
<%=
html(self) do
div class: 'ruby2html-section' do
h2 "This section is powered by Ruby2html!"
p "Isn't it beautiful? 😍"
end
end
%>
<%= render ModernComponent.new %>
```
In this example, you can see how Ruby2html seamlessly integrates with existing ERB code. This approach allows you to:
- Keep your existing ERB templates and partials
- Gradually introduce Ruby2html in specific sections
- Use Ruby2html in new components while maintaining older ones
- Refactor your views at your own pace
Remember, there's no rush! You can keep your `.erb` files and Ruby2html code side by side until you're ready to fully transition. This flexibility ensures that adopting Ruby2html won't disrupt your existing workflow or require a massive rewrite of your application. 🌈
