Project: deklarativna - The Ruby Toolbox

#Deklarativna ###A declarative HTML embedded DSL

##Purpose The purpose of Deklarativna is to make HTML template creation an integrated part of frontend development, allowing the programmer to write human readable code with not much effort.

##Conception This work has been started as a tool for teaching declarative programming and DSL creation to universitary students. This is a work in progress and I hope someday will have integration with the most popular web frameworks

##Current Status All HTML common tags are implemented. Full support for XML tags with xml_single_tag and xml_double_tag is added.

Updates

Sinatra integration is demonstrated on the examples

HTML/XML Fully supported

rubygem released

Next Steps:

Rails plugin

CSS 2, 3 wrapper??

jQuery helpers ??

##Installation You can download this gem from RubyGems.org by running

$ gem install deklarativna

##Usage ###Function Based Approach

require 'deklarativna'
require 'deklarativna_utils'

include Deklarativna
include DeklarativnaUtils

renderable = html {[
              head {
                  css {
                      ".hello { float: right; color: #456546 }"
                  }
              },
              body {
                  p("class"=>"hello") {
                      "Hello World!"
                  }
              }
            ]}

HTMLExporter.new.launch_rendered_html_on_browser renderable

###Class Based Approach

require 'deklarativna'
require 'deklarativna_utils'

class ChildTemplate < BaseTemplate
  def _head
    css { "h1 { color: red; }" }
  end

  def _body
    [
      h1 { "Deklarativna" },
      p { "how cool is this??" },
      p { "really cool" }
    ]
  end
end

include DeklarativnaUtils

HTMLExporter.new.launch_rendered_html_on_browser ChildTemplate.new.render

###Sinatra Integration

require 'rubygems'
require 'sinatra/base'
require 'deklarativna'

class IndexTemplate < BaseTemplate
  def _body
    [
      p { "Testing Dinamic File Generation using sinatra" },
      table("border"=>"1") {[
        tr {[
          td { "row 1, value 1" },
          td { "row 1, value 2" }
        ]},
        tr {[
          td("colspan"=>"2") { "Only value in this row" }
        ]}
      ]}
    ]
  end
end

class DeklarativnaSinatra < Sinatra::Base
  get '/' do
    IndexTemplate.new.render
  end
end

DeklarativnaSinatra.run!

Test this by running

$ ruby dinamic_sinatra_example.rb

And open your browser on localhost:4567

Now you can surf the examples on the examples directory! There are some pretty cool examples, and I will be publishing more complex examples over time.

I'm coding a blog using Deklarativna, Check it out! https://github.com/dlitvakb/Blogging-Deklarativna
