Create menus with multi-level and a Domain Specific Language (DSL) for menus. It's extremely Object Oriented. It still doesn't have code for render, but you can combine it with other mechanism for rendering, like simple-navigation or other.

Semantic Versioning (http://semver.org/)

This gem is following the Semantic Versioning

Features

• Compatible with any application or framework.
• Singleton registry for menus (ActiveMenu::Registry), you can define menus anywhere. (But, use your conscience to a good design.)
• Domain Specific Language
• You can define the menu along multiple gems(like plugins of Rails)

Using simple-navigation with activemenu

Initial example

  ActiveMenu::create('admix-nav') do |nav|        

    nav.child :dashboard do |dashboard|
      dashboard.text = Proc.new { t('dashboard.dashboard') }
      dashboard.href = Proc.new { admix_root_url }
      dashboard.icon = 'icon-flag'
    end

    nav.child :general do |general|
      general.text = Proc.new { t('general.general') }
      general.icon = 'icon-flag'
      general.href = 'javascript:;'
      general.visible = Proc.new {current_user.has_role?(:admin)}
    end

    nav.child :content do |content|
      content.text = Proc.new { t('content.content') }
      content.href = 'javascript:;'
      content.icon = 'icon-flag'
    end

  end

Installation

Add this line to your application's Gemfile:

gem 'activemenu'

And then execute:

$ bundle

Or install it yourself as:

$ gem install activemenu

Usage

Creating menus objects in the registry

ActiveMenu::create(:mymenu)
#....
# In another gem you can use 
@menu = ActiveMenu::get(:mymenu).child do |sub|
  sub.content = 'My content'
end

exists?

  ActiveMenu::create(:someid)
  ActiveMenu::exists?(:someid) # == true
  ActiveMenu::exists?(:this_id_doesnt_exists) # == false

visible

  ActiveMenu::get(:someid).visible

Get the menu

You can retrieve the menu instance with the method get...

  @menu = ActiveMenu::get(:someid)

or, you can use a block too and retrieve it as the first param.

  ActiveMenu::get(:someid) do |menu|
    menu.id # The menu id
  end

Set options to the menu

These options are write to a hash, that you can use with other gem to render it.

  @menu = ActiveMenu::get(:someid)
  @menu.myoption = 'my value'
  @menu.myoption2 = Proc.new { my_dynamic_method #that will run when I use this option }

Standard DSL (Domain Specific Language) options

To facilitate the creating of menus, there are some methods to help you organize the options standard.

visible(value=nil)

You can pass a variable or a Proc to be executed to the visible method.

  ActiveMenu::create('admix-nav') do |nav|        
    nav.child :general do |general|
      general.text = Proc.new { t('general.general') }
      general.icon = 'icon-flag'
      general.visible = Proc.new {current_user.has_role? :admin}
    end
  end

end

tag(value=nil)

You can set the tag for the menu element or can retrieve it.

    @menu = ActiveMenu::get(:my_menu)
    @menu.tag :li
    @menu.tag # --> :li
    @menu.tag :div
    @menu.tag # --> :div

text()

Nested menus

@menu = ActiveMenu::Menu.new(:mainmenu, href: 'http://example.com') 
# def initialize(id, options={}, &block) .... yield(self) if block_given?
@menu.child(:mychild, href: "test") do |sm|
  sm.text 'My child'
  sm.child(:mysubchild, href:'test 2') do |ssm|
    ssm.text = 'My subchild'
  end
end
# Let's improve this DSL, contribute please.
