#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.
##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.rbAnd 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
