When the string containing null character is passed to WebDialog.set_html() the page is loaded up to this characted.

Here is the test case:

NASTY_STRING = "asd\000dsa"

UI.menu("Plugins").add_item("test set_html") do
	dlg = UI;;WebDialog.new("test set_html", true);
	dlg.set_html(NASTY_STRING)
	dlg.show() # only "asd" is displayed
end

UI.menu("Plugins").add_item("test set_file") do
	dlg = UI;;WebDialog.new("test set_file", true);
	temp_file = ENV['TEMP'] + "\\test_set_file.html"
	File.open(temp_file, "wb") do |file|
		file.write(NASTY_STRING)
	end	
	dlg.set_file(temp_file) # only "asddsa" is displayed
	dlg.show()
end

I understand this is pretty nasty edge case, but still can produce mind boggling results/surprises.

Great, thank you. I knew about linetool.rb but liked the built-in tool better.

Now I think I'll settle with this enhanced version of linetool.rb as I understand it's not possible with the built-in tools anyway.

And sorry, xLine.rb doesn't look like what I need, that http://www.smustard.com/script/Xline page says "Convert edges to construction lines", but thank you anyway.

Through Ruby API it is possible to turn existing construction line into finite length one by setting start/end properties. Described here: http://code.google.com/intl/ru-RU/apis/sketchup/docs/ourdoc/constructionline.html

Now is there a way to create finite length construction line manually? I have read the manual for Protractor tool and failed to find any way to do that. Maybe I should use other tool?

def test_error1
   begin
      test_error2 # code which may contain an error
   rescue Exception => e
      do_rescue(e, "Test Error")
   end#begin
end#def

can be even reduced to

def test_error1
  test_error2 # code which may contain an error
rescue Exception => e
  do_rescue(e, "Test Error")
end

But what really bothers me is that there is no option to make Ruby console pop up when there are new messages and stay hidden otherwise.

As for now I guess I would just keep a file with

Sketchup.send_action("showRubyPanel;")

in the Plugins folders while doing active development.

Thank you for your quick reply.

And yeah I noticed your suggestion in one of the above links too.

The observer solution seems a little kludgey to me, especially when you can create the needed leader manually with the Text tool.

So I'm still pretty new to SketchUp development, how that observers solution would work when say I would like to move my *.skp file to the other PC? I would obviously have to move it with the script which sets up observers?

So far I have found these links, both of which indirectly confirm that this is impossible with the current API. Can anybody confirm/deny this?

When working with the Text tool you can anchor the created leader to Endpoint or Face of the component. Then when you move the component the leader follows the original point on component (or face, etc.).

Is there a way to add a text with the leader by

add_text (Sketchup;;Entities)

function, with leader being anchored to specific Endpoint in my component?

Thanks in advance.
