MenuMotion

MenuMotion is a RubyMotion wrapper inspired by Formotion for creating OS X menus with a syntax that should feel familiar if you've used Formotion.

Installation

Add this line to your application's Gemfile:

gem "menu-motion"

And then execute:

$ bundle

Or install it yourself as:

$ gem install menu-motion

Usage

Here's an awesome graphic of a menu:

|‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾|
| [icon] First Item > |‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾|
|---------------------| First Subitem > |‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾|
| ۞ About MenuMotion |-----------------| First Action    |
| Quit                | Some Action     | ✓ Second Action |
|_____________________|_________________|_________________|

And the Ruby to generate this menu:

menu = MenuMotion::Menu.new({
  sections: [{
    rows: [{
      icon: "icon.png",
      title: "First Item",
      sections: [{
        rows: [{
          title: "First Subitem",
          rows: [{
            title: "First Action",
            target: self,
            action: "first_action:",
            object: some_object
          }, {
            title: "Second Action",
            target: self,
            action: "second_action",
            checked: true
          }]
        }]
      }, {
        rows: [{
          title: "Some Action",
          target: self,
          action: :some_action
        }]
      }]
    }]
  }, {
    rows: [{
      title: "About MenuMotion",
      action: "orderFrontStandardAboutPanel:",
      image: "gear"
    }, {
      title: "Quit",
      action: "terminate:"
    }]
  }]
})

Sections

Sections are used to add dividers between sets of "rows" (menu items).

menu = MenuMotion::Menu.new({
  sections: [{
    rows: []
  }, {
    rows: []
  }
})

Submenus

To link a menu item to a submenu, simply define sections or rows within the row item that should display the submenu.

menu = MenuMotion::Menu.new({
  rows: [{
    title: "Menu item",
    rows: [{
      title: "Submenu item 1"
    }, {
      title: "Submenu item 2"
    }]
  }]
})

Actions

Adding an action to a menu item is easy. Just define the target and action parameters. Actions that don't require the sender to be passed can be defined as a String or a :symbol.

menu = MenuMotion::Menu.new({
  rows: [{
    title: "Basic Action",
    target: self,
    action: :basic_action
  }, {
    title: "Pass the menu item to the action",
    target: self,
    action: "action_with_sender:"
  }]
})

def basic_action
  puts "Hello World"
end

def action_with_sender(sender)
  puts "Hello from #{sender}"
end

Keyboard Shortcuts

Keyboard shortcuts can be assigned to menu items with a simple string assigned to the :shortcut parameter. The string can include multiple modifier keys, followed by the final key to be assigned ({modifier+}{modifier+}{key}):

menu = MenuMotion::Menu.new({
  rows: [{
    title: "Item 1",
    shortcut: "command+1"
  }, {
    title: "Item 2",
    shortcut: "control+shift+2"
  }]
})

Modifier Key Options

• shift
• control, ctl, ctrl
• option, opt, alt, alternate
• command, cmd

Validation

MenuMotion implements the NSMenuValidation protocol for determining whether a menu item should be enabled or not. Simply pass a Proc to the :validate parameter that returns true if the menu item should be enabled or false if the menu item should be disabled:

menu = MenuMotion::Menu.new({
  rows: [{
    title: "Menu item",
    tag: :main_item
    rows: [{
      title: "Submenu item 1",
      tag: :submenu_item1,
      target: self,
      action: "do_something:",
      validate: ->(menu_item) {
        true # or false
      }
    }]
  }]
})

Images

You can assign an image to a menu item with the image option. This option can be sent as a String or an NSImage.

menu = MenuMotion::Menu.new({
  rows: [{
    title: "Menu item",
    tag: :main_item,
    image: 'main_item_image' # the file extension is optional
    # or:
    # image: NSImage.imageNamed('main_item_image')
  }]
})

Custom Views

Menu items can have custom views applied to them with the view option. In order for the view to be interactable, you need to set a target and action on the menu item even if the custom view handles clicks for you.

menu = MenuMotion::Menu.new({
  rows: [{
    title: "Menu item",
    tag: :main_item,
    view: MyNSViewSubclass.new,
    target: self,
    action: :blank_action
  }]
})

def blank_action
  # Nothing to see here, move along please.
end

Updating Menu Items

Assign tags to menu items that will need to be updated.

menu = MenuMotion::Menu.new({
  rows: [{
    title: "Menu item",
    tag: :main_item
    rows: [{
      title: "Submenu item 1",
      tag: :submenu_item1,
      target: self,
      action: "do_something:"
    }, {
      title: "Submenu item 2",
      tag: :submenu_item2,
      target: self,
      action: "do_something:"
    }]
  }]
})

# Let's update the first item's title:
menu.update_item_with_tag(:main_item, {
  title: "Hello World"
})

# And give the first submenu item a submenu.
# The target and action will not be used if a submenu is defined.
menu.update_item_with_tag(:submenu_item1, {
  rows: [{
    title: "Click me",
    target: self,
    action: "clicked"
  }]
})
