Crossbeams::Layout

A DSL for designing an HTML page layout. Build up the structure of the page in Ruby code and then call render to generate an HTML string.

Installation

Add this line to your application's Gemfile:

gem 'crossbeams-layout'

And then execute:

$ bundle

Or install it yourself as:

$ gem install crossbeams-layout

Usage

Basic example:

ui_rule = {
  fields: {
    a_field: { renderer: :select, options: ['Value X', 'Values Y'], required: true }
  },
  form_object: OpenStruct.new(a_field: 'Value X'),
  name: 'formname'
}

layout = Crossbeams::Layout::Page.build(ui_rule) do |page|
  page.section do |section|
    section.add_caption 'Main'
    section.add_text 'An explanation'
    section.show_border!
  end

  page.form_object ui_rule.form_object
  page.form_values form_values
  page.form_errors form_errors
  page.form do |form|
    form.action '/path/to/save_form'
    form.remote!
    form.add_field :a_field
  end

  page.row do |row|
    row.col do |col|
      col.add_text 'Some minor heading', wrapper: :h2
    end
    row.col do |col|
      col.add_text 'Some other text', wrapper: :p
    end
  end
end

# In a view:
layout.add_csrf_tag(csrf_tag) # (if csrf used in forms)
layout.render
