+# Gon-sinatra gem — get your Sinatra variables in your js
+
+
+If you need to send some data to your js files and you don't want to do this with long way through views and parsing - use this force!
+
+Now with [Rabl](https://github.com/nesquena/rabl) support!
+
+## Usage
+
+`views/application.erb`
+
+``` erb
+<head>
+ <title>some title</title>
+ <%= include_gon %>
+ <!-- include your action js code -->
+ ...
+```
+
+To camelize your variables in js you can use:
+
+``` erb
+<head>
+ <title>some title</title>
+ <%= include_gon(:camel_case => true) %>
+ <!-- include your action js code with camelized variables -->
+ ...
+```
+
+You can change the namespace of the variables:
+
+``` erb
+<head>
+ <title>some title</title>
+ <%= include_gon(:namespace => 'serverExports') %>
+ <!-- include your action js code with 'serverExports' namespace -->
+ ...
+```
+
+You put something like this in the Sinatra action:
+
+``` ruby
+@your_int = 123
+@your_array = [1,2]
+@your_hash = {'a' => 1, 'b' => 2}
+gon.your_int = @your_int
+gon.your_other_int = 345 + gon.your_int
+gon.your_array = @your_array
+gon.your_array << gon.your_int
+gon.your_hash = @your_hash
+
+gon.all_variables # > {:your_int => 123, :your_other_int => 468, :your_array => [1, 2, 123], :your_hash => {'a' => 1, 'b' => 2}}
+gon.your_array # > [1, 2, 123]
+
+gon.clear # gon.all_variables now is {}
+```
+
+Access the varaibles from your JavaScript file:
+
+``` js
+alert(gon.your_int)
+alert(gon.your_other_int)
+alert(gon.your_array)
+alert(gon.your_hash)
+```
+
+With camelize:
+
+``` js
+alert(gon.yourInt)
+alert(gon.yourOtherInt)
+alert(gon.yourArray)
+alert(gon.yourHash)
+```
+
+With custom namespace and camelize:
+
+``` js
+alert(customNamespace.yourInt)
+alert(customNamespace.yourOtherInt)
+alert(customNamespace.yourArray)
+alert(customNamespace.yourHash)
+```
+
+## Usage with Rabl
+
+Now you can write your variables assign logic to templates with [Rabl](https://github.com/nesquena/rabl).
+The way of writing Rabl templates is very clearly described in their repo.
+
+Profit of using Rabl with gon:
+
+ 1. You can clean your controllers now!
+ 2. Work with database objects and collections clearly and easyly
+ 3. All power of Rabl
+ 4. You can still be lazy and don't use common way to transfer data in js
+ 5. And so on
+
+For using gon with Rabl you need to create new Rabl template and map gon
+to it.
+For example you have model Post with attributes :title and :body.
+You want to get all your posts in your js as an Array.
+That's what you need to do:
+
+ 1. Create Rabl template. I prefer creating special directory for
+ templates which are not view templates.
+
+ `goners/posts/index.rabl`
+
+ ``` rabl
+ collection @posts => 'posts'
+ attributes :id, :title, :body
+ ```
+
+ 2. All you need to do after that is only to map this template to gon.
+
+ ``` ruby
+ get '/' do
+ # some logic
+ @posts = [some_objects] # Rabl works with instance variables of controller
+
+ gon.rabl 'goners/posts/index.rabl'
+ # some logic
+ end
+ ```
+
+ Thats it! Now you will get in your js gon.posts variable which is Array of
+ post objects with attributes :id, :title and :body.
+
+In javascript file for view of this action write call to your variable:
+
+``` js
+alert(gon.posts)
+alert(gon.posts[0])
+alert(gon.posts[0].post.body)
+```
+
+P.s. If you didn't put include_gon tag in your html head area - it
+wouldn't work. You can read about this in common usage above.
+
+### Some tips of usage Rabl with gon:
+
+If you don't use alias in Rabl template:
+
+``` rabl
+collection @posts
+....
+```
+
+instead of using that:
+
+``` rabl
+collection @posts => 'alias'
+....
+```
+
+Rabl will return you an array and gon by default will put it to variable
+gon.rabl
+
+Two ways how you can change it - using aliases or you can add alias to
+gon mapping method:
+
+``` ruby
+# your logic stuff here
+
+gon.rabl 'path/to/rabl/file', :as => 'alias'
+```
+
+## Installation
+
+Manually install gon-sinatra gem: `$ gem install gon-sinatra`
+
+Add requirement to your app file
+
+``` ruby
+require 'gon-sinatra'
+```
