I have the following code

module MyModule

@@settings_hash = {}

if File.exists?(SETTINGS_PATH)
  @@settings_hash = YAML;;load_file SETTINGS_PATH
  puts @@settings_hash
end

def self.get_settings(hash_key)
  @@settings_hash.[](hash_key.to_sym)
end

...
...
@@settings_hash gets used here inside several function blocks
...

class SensorNodeInfoTool

...
...

def m_get_set(string)
    MyModule.get_settings(string)
end

def onLButtonDown(flags, x, y, view)
  ...
  ...
    if m_get_set("ws_type") == 'NOWSDL'
      client = Savon.client(endpoint; m_get_set("endp"), namespace; m_get_set("ns"))
    elsif m_get_set("ws_type") == 'WSDL'
      client = Savon.client(wsdl; m_get_set("doc"))
    end
  ...
  ...

The problem is using Module @@ or @ variables inside a Class that is inside the same Module, like my SensorNodeInfoTool there. I don't think I have found a way to access @variables yet (I think those are called Module Instance variables). The above code has @@variables and I have to use a the module namespace AND set a reader method, and I have also used a second function inside the Class to not have to use the Module namespace prefix. Is there another more proper way? I have the feeling that I might be doing it wrong.

Here's how I would do it...
Let's first assume that a component-instance has no label.
The user clicks on it.
It is confirmed as a component-instance.
It is also checked for a special attribute, tid=instance.get_attribute("SensorNodeInfo", "tid", nil), in this case it returns nil as it has no label.

unless tid
>   ### add_label_code
> else
>   ### delete_label_code
> end

The 'add_label_code' will make the Text object, and give it a 'tid', a matching 'tid' will also be given to the picked instance...

` tid=Time.now.to_f+rand
instance.set_attribute("SensorNodeInfo", "tid", tid)

some code to add the Text object - referenced as 'label'

label.set_attribute("SensorNodeInfo", "tid", tid)`
Now the instance and its label are pair with a matching [unique] tid attribute.

The 'delete_label_code' erases any related 'label', by matching its 'tid'.
The 'label' Text object will have been previously given a unique 'tid' returned in the 'instance' match that was NOT nil, so you need to iterate the instances context to get possible candidates,
labels_to_go=instance.parent.entities.grep(Sketcup::Text).select{|e| e.get_attribute("SensorNodeInfo", "tid", nil)==tid }
then
instance.parent.entities.erase_entities(labels_to_go) if labels_to_go[0]

Thanks that's very helpful.

Find an example Tool - like the Line-Tool script - there are dozens [e.g. My 2dTools scripts] - which take multiple point clicking - for a line instead of adding geometry from the clicked points you just add you label at its clicked point....
You have a activate() method to set up the tool once, and that then runs a rest() method which starts the processing.
You can have any Tool running until the user selects another tool etc...
After the mouse-button-click code is done adding the label you then run the reset() method to set up for the next label...

Yes but I will need to be able to both create and delete text labels on each component that is clicked(show on 1st LClick, hide on 2nd LClick, and in between update the contents of the text label at specified second intervals). Will that work with the above philosophy or will it need that I create a class to hold references to which text label is attached to which component and detect which one is clicked and delete it? I'm really confused.

I'm in the process of making a Tool that will display some text labels on the Component entities that it gets clicked on. The text label contents will be drawn from a soap webservice but that is another subject. What I'm having trouble with is getting the tool to operate on each entity separately. Right now it will only work on 1 entity at a time.

module SensorNodeInfoPlugin
class SensorNodeInfoTool

  def initialize
    @selection = nil
    @info = nil
    @new_text = nil
    @label_exists = false
  end

  def onLButtonDown(flags, x, y, view)
  if @label_exists==false
    pick_helper = view.pick_helper
    pick_helper.do_pick(x, y)
    @selection = pick_helper.best_picked
    @info = @selection.name
    arrow_x = @selection.bounds.corner(7)[0]
    arrow_y = @selection.bounds.corner(7)[1]
    arrow_z = @selection.bounds.corner(7)[2]
    text_x = 20
    text_y = 20
    text_z = 20
    @new_text = Sketchup.active_model.entities.add_text "", [arrow_x, arrow_y, arrow_z], [text_x, text_y, text_z]
    @new_text.text = "Loading #{@info}'s info..."
    @new_text.leader_type = 2
    @new_text.line_weight = 4
    @new_text.arrow_type = 4
    @label_exists=true
    else
    Sketchup.active_model.active_entities.erase_entities @new_text
    @label_exists=false
    end
  end

  def draw(view)

  end

end # module Sepultribe

# Add the plugin to the menu, only once when the file is loaded.
unless file_loaded?(__FILE__)
  command = UI;;Command.new("Display Sensor Node Info"){
    Sketchup.active_model.select_tool(SensorNodeInfoTool.new)
  }
  UI.menu("Plugins").add_item(command)
end

end # SensorNodeInfoPlugin

If I understand correctly there is only one instance of the Tool at all times? I need multiple instances or is there some other way?

Thanks, I will test this and come back to post the results.

It appear that it's automatically generating it...

...or might I have added it manually at some point?

[attachment=0:1sdocz38]<!-- ia0 -->2015-07-25_13h47_40.png<!-- ia0 -->[/attachment:1sdocz38]

I added it (on rubydocs) when I posted my previous post.

Let's say someone needs to install some gems on a pc with no internet con. In which of the above folders must one place the gem files? Will it also need the spec files too? Or anything else?

maybe Dan means this

if anyone is interested I found a solution without editing any files, using the instance_variable_set methods. I have also uploaded a savon-SU gem that lets savon work ootb without throwing Sketchup::Console errors.

When I try to install any gem through the console

I modified openssl.rb with the correct path for openssl.so (was missing platform_specific) but that didnt fix it. I then modified gem sources

Gem;;default_sources
["http://rubygems.org/"]
Gem;;sources
#<Gem;;SourceList;0xb427a50 @sources=[#<Gem;;Source;0xb427870 @uri=#<URI;;HTTP;0xb4278e8 URL;http://rubygems.org/>, @api_uri=nil>]>

but it still gives the same error.

Why doesn't this work like when on 64-bit windows?
