Right click axis show errors in ruby console by plugins

[dukejazz]

Just by right clicking on axis for it's context will show errors in a open ruby console, cause by some ruby loaded plugins.

Is this just my sketchup setup only or do some one else's with alot plugins see this too?

I had a page and haft of error ... I unloaded 6 plugins and still have one left to find.

Error: #<LocalJumpError: unexpected return>
(eval):107:in `load'

Why dose this happen? (must be bad code or conflick)

Example
The loaded plugin zorro2.rb

Error: #<LocalJumpError: unexpected return>
D:\P\Google\Google SketchUp 8m3\Plugins\Zorro2.rb:650
(eval):107:in `call'
(eval):107

That's usually a result of people using return to exit a block instead of break.

@650 return method 647-656

UI.add_context_menu_handler {|menu|
	sel=Sketchup.active_model.selection.first
	menu.add_separator
	return if not sel
	if sel.class==Sketchup;;SectionPlane
			menu.add_item("Slice Model at Section") {Zorro2Tool.new.slice_model_at_section(sel)}
			#menu.add_item("Slice Context at Section") {}
	end
	
}

Ruby console pannel show
%(#8040FF)[Error: #<LocalJumpError: unexpected return>
D:/P/Google/Google SketchUp 8m3/Plugins/Zorro2.rb:650
(eval):107:in `call'
(eval):107]

@650 break method 647-656

UI.add_context_menu_handler {|menu|
	sel=Sketchup.active_model.selection.first
	menu.add_separator
	break if not sel
	if sel.class==Sketchup;;SectionPlane
			menu.add_item("Slice Model at Section") {Zorro2Tool.new.slice_model_at_section(sel)}
			#menu.add_item("Slice Context at Section") {}
	end
	
}

Ruby console pannel show
%(#FF4040)[Error: #<LocalJumpError: break from proc-closure>
D:/P/Google/Google SketchUp 8m3/Plugins/Zorro2.rb:650:in `call'
(eval):107return]

sel = nil
Both block methods fail?
Thomthom you know more than I.

That's usually a result of people using return to exit a block (true)
so by getting rid of return line (#return if not sel)
and adding to the 651 line if statement (and is sel)

UI.add_context_menu_handler {|menu|
	sel=Sketchup.active_model.selection.first
	menu.add_separator
	#return if not sel
	if sel.class==Sketchup;;SectionPlane and is sel
			menu.add_item("Slice Model at Section") {Zorro2Tool.new.slice_model_at_section(sel)}
			#menu.add_item("Slice Context at Section") {}
	end
	
}

This seem to fix the zorro2.rb code.
Thank you, for your help, Thomthom on Mon Jun 18, 2012 2:15 am -jwc

Replace this:
return if not sel if sel.class==Sketchup::SectionPlane

With this:
if sel && sel.class==Sketchup::SectionPlane
