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.

@tig said:

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?

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.

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?

just commented out Logger.New in the lib/savon/options.rb file

    def initialize(options = {})
      @option_type = ;global

      defaults = {
        ;encoding                  => "UTF-8",
        ;soap_version              => 1,
        ;namespaces                => {},
#        ;logger                    => Logger.new($stdout),
        ;log                       => false,
        ;filters                   => [],
        ;pretty_print_xml          => false,
        ;raise_errors              => true,
        ;strip_namespaces          => true,
        ;convert_response_tags_to  => lambda { |tag| tag.snakecase.to_sym},
        ;convert_attributes_to     => lambda { |k,v| [k,v] },
        ;multipart                 => false,
        ;adapter                   => nil,
        ;use_wsa_headers           => false,
        ;no_message_tag            => false,
        ;follow_redirects          => false,
        ;unwrap                    => false,
        ;host                      => nil
      }

and all is working good finally..... I was ready to hit my head on the wall.

Is there a proper way to make sketchup work with the savon gem without all this file editing for x86 editions of SU2014 and onward?

@dan rathbun said:

Might be a good application for bundler:
http://bundler.io/#getting-started

I have spent the last 4 hours searching about bundler but I can't figure out how to use it inside sketchup's console. I'm really stressed... Can you give me some hints as to what it is I have to do?

EDIT: I managed to get the nokogiri-1.6.6.2-x86-mingw32 version to install by modifying rubygems.rb and platform.rb in the following places

# Array of platforms this RubyGems supports.
def self.platforms
        @platforms ||= []
        if @platforms.empty?
          @platforms = ["x86-mingw32", Gem;;Platform.local]
        end
        @platforms
      end

  def self.match(platform)
    Gem.platforms.any? do |local_platform|
      platform.nil? or
        local_platform == platform or
        (local_platform != "x86-mingw32" and local_platform =~ platform)
    end
  end

  def self.new(arch) # ;nodoc;
    case arch
    when Gem;;Platform;;CURRENT then
      Gem;;Platform.local
    when "x86-mingw32", nil, '' then
      "x86-mingw32"
    else
      super
    end
  end

Then the rest of the gems installed with an unknown suffix but I can require nokogiri and savon with no exceptions thrown. I would like to find a better solution as this is hacking with the SU files which is not that good to do.

When I thought I had at least solved my problem I tried to run a simple savon client that works perfectly in my ruby installation and I get many errors on Sketchup::Console, logger.rb and savon.rb

client = Savon.client(wsdl; "http://www.w3schools.com/webservices/tempconvert.asmx?wsdl")
response = client.call(;celsius_to_fahrenheit, message; { "Celsius" => "25" })
puts response.body

And this is the error log :

Error; #<TypeError; no implicit conversion of Sketchup;;Console into String>

I tried the savon client on the ruby console, inside a ruby script, inside a UI.messagebox() with the same results in all.

@jim said:

Try the 32-bit sketchup if you are not already using it.

I use the 32-bit version of Ruby on my 64-bit Wondows because some gems just do not work when I tried. Nokogiri was one of them.

I only used x86 versions of sketchup for my testing, as I need my plugin to work on old xp machines at school. I'm really curious how Dan managed to do it so easily on a 64-bit version of sketchup... I must be so unlucky. I'll try to install a x64 SU now and see if there's any luck...

edit: confirm 64 bit SU15 doesnt throw error on savon install, BUT when I try to use it

Weird thing is

require 'nokogiri'

returns true.

I tried to add things to $LOAD_PATH to see my external ruby 2.0 installation where savon exists to no avail.

Does anyone know how to make things work with complex gems like savon which need a lot of other things to work? I have tried both 2014M1 and 15.3.330 both x86.

thanks

EDIT: failed on latest 2015 (x86) version too. I'm on w7 x64 don't know if that's the issue...

EDIT2: appended external ruby 2.0 paths to $LOAD_PATH (which has savon installed) and can't require or install savon still. this is very frustrating... Also tried pasting nokogiri.so to PLUGIN folder, to TOOLS folder, and several others with no success...

EDIT3: installed devkit to ruby 2.0 external installation and added main directory to load_path but still no success.

very much appreciated, thanks for the detailed response

Are sketchup.rb and extensions.rb still required for SU plugins? What does init() help with? And what does a singleton class give us since everything is inside a module?

Hi Driven,

What you gave me is far more than I expected. Don't apology. Such short code is not so hard to understand but at first glance I didn't understand why using an array as counter and some other constructions. I had never met html+Javascrit+Ruby as well. That's why I felt a bit confused but your answers make all that clear in my mind.

Do you know how to refresh the dlg content from a script. something like

> for i in 0..2	
> 	@count += 1
> 	@dlg.set_html(dlg_html_content())
> 	
> 	#how to refresh the dlg content?	
> 	#dlg.refresh is not available
> 	#is there a way to force a refresh?
> 	sleep (1.0/2.0)
> end	
> @dlg.close
> 

Have a good Sunday

Hi. You can send javascript code to execute it inside the webdialog from sketchup ruby with the execute_script() method.

if dlg is your webdialog instance object then

js_command = "location.reload()"
dlg.execute_script(js_command)

something like this should work

Hello all,

I am also looking at creating a plugin which will import some data from a large (5OOmb+) XML file (provided by a third Party) I have the import script written using Nokogiri but am having trouble installing it in SU's ruby. I reda through pedrobaracho's post, and will give it some more attention to see if i can figure it out, but does anyone know if an easy, preferably native way to do this import?

I haven't tried pedrobaracho's way yet, but I think it's either that way (installing all required gem files inside your sketchup or plugin folder) or using an external ruby installation which will be the same version as your sketchup ruby version and editing the $LOAD_PATH variable to include that location. I'm also looking into this and I haven't completely figured it out myself. Good luck
