Overview

Interfaces can be configured to be part of a named group. Once an interface is a member of group, the group can be affected by other controls. For example, assuming the client application is a simple Git client, it may have a group called ‘commit’. The ‘commit’ group will contain the interfaces ‘diff’ (to show the changes), ‘staged’ (to show which files are staged) and ‘unstaged’. A refresh of the ‘commit’ group would cause all interfaces belonging to the group to refresh. Similarly, showing or hiding the group would of course, show or hide the interfaces of that group.

Instance Attribute Details

#client ⇒ Object (readonly, protected) Originally defined in module DSL

Returns The object instance where the DSL is being used.

Returns:

  • (Object) —

    The object instance where the DSL is being used.

#model ⇒ void (readonly, protected) Originally defined in module DSL

This method returns an undefined value.

Returns The new model object which the DSL is constructing.

Class Method Details

.group(name, &block) ⇒ Vedeu::Groups::Group

Specify a new group of interfaces with a simple DSL. Creating a group with the same name as an existing group overwrites the existing group.

The example below resembles ‘vim’ (the popular terminal-based text editor):

Vedeu.group :title_screen do
  add :welcome_interface
  # ... some code
end

Vedeu.group :main_screen do
  add :editor_interface
  add :status_interface
  add :command_interface
  # ... some code
end

or more succinctly:

Vedeu.group :main_screen do
  members :editor_interface,
          :status_interface,
          :command_interface
  # ... some code
end

or when defining an interface:

Vedeu.interface :some_interface do
  group :some_group
  # ... some code
end

Parameters:

  • name (String|Symbol) —

    The name of this group.

  • block (Proc)

Returns:

Instance Method Details

#add(name) ⇒ Vedeu::Groups::Group

end

def add(name)
  model.add(name)
end

#attributes ⇒ Hash<Symbol => void> (private) Originally defined in module DSL

Note:

Specific DSL classes may be overriding this method.

Returns the default attributes for the new model.

Returns:

  • (Hash<Symbol => void>)

#initialize(model, client = nil) ⇒ void Originally defined in module DSL

Returns an instance of the DSL class including Vedeu::DSL.

Parameters:

  • model (void) —

    The model class which the DSL class is wrapping.

  • client (void) (defaults to: nil) —

    The class where the DSL methods are being used.

#members(*names) ⇒ Array<String>

Add the named interfaces to this group in bulk.

Vedeu.group :main_screen do
  members [:editor_interface,
           :some_interface,
           :other_interface]
end

Parameters:

  • names (Array<String|Symbol>)

Returns:

  • (Array<String>)
