How to debug?

I know, I'm a complete outsider in this discussion, but I have a question and an idea.
My question: In what debugging situations is it necessary to restart Sketchup?
And my idea:
A plugin that resets Sketchup to it's initial state. So you never have to restart SU or manually reload a plugin to test a script.
If your script makes menu items or toolbars you will [usually] have trapped it with
file_loaded()so you don't get multiple entries... so if you change those reloading the script won't affect those... but otherwise any code changes are usually reflected in the tool's operation without a need to restart if you useload "myscript.rb"....... if you tool has decent start/commit blocks to undo what it's just done [incorrectly] you rarely need to restart Sketchup after tweaking your code... -

In additions to what TIG mentioned in regard to menus, you might want to restart after doing some major refactoring where you might have renamed methods etc. You might still be calling the old method.
And there might be things your plugin has to do at startup, such as some observers. But it belong to the rare cases. -
Thanx guys,
I'm working with dynamic screen notes and dynamic tooltips, and have to restart SU all the time to get them
refreshed.. But that's not common for most plugins I suppose. -
A tooltip for a UI::Command instance object can be changed at ANY time, simply by calling the instance object's tooltip= method, with an argument that is different than what the current tooltip text is.
This means that you must make and keep available, a reference (sloppily called a variable,) to that instance object, so you can later call it's instance methods.
You can also change the status bar text and the validation proc dynamically in the same way.

Its enough to make a grown man cry! It only took me 3 hours to find the 2 letter typing error. I hope this is not age related?
There was no hint of a problem in the Ruby console, Notepad++ or SciTE. Its enough to make one 
if( @stud != "YES" ) #...get the number of joists required for the related @vec/@joc #...@soc = joist on center spacing @num_stud=((@vec/@soc)+1).to_i definitions=model.definitions count=definitions.add entities=count.entities #...draw 1st stud base=entities.add_face(@pt1, @pt3, @pt33, @pt11) base=entities.add_line(@pt1, @pt33) base=entities.add_line(@pt3, @pt11) #...transform stud location t=Geom;;Transformation.translation(Geom;;Vector3d.new(0, 0, 0)) entities=model.active_entities entities.add_instance(count, t) #...copy studs to their new locations i = 1 while i < @num_stud # Transformation i = i + 1 vec = @pt5 - @pt6 # width between which studs are to be drawn vec.length = @soc*(i-1) t=Geom;;Transformation.translation(Geom;;Vector3d.new(0,@soc*(i-1), 0)) t=Geom;;Transformation.translation(vec) entities.add_instance(count, t) end end if # end if @studI feel better now!

Wow... that's strange! An empty argument creates a new definition, whose name is "Component". The API does not mention this!!!
And Jim.. got it correct... although I would think Ruby would issue a
ScriptError, something like "blah blah blah...`end' expected" -
yup! Jim is right!. So back to the initial subject, is there a debug routine for such errors?
your editor should be causing a high pitch sound for end if or at least a blicking, or bouncing simile.

I was going to suggest checking the syntax, but you would need to have Ruby version 1.8.6 installed (not a bad idea if you are developing plugins.)

would you please elaborate on I would install Ruby version 1.8.6 within the current Ruby/SU environment.
Currently I simply use NotePad ++ or SciTE to edit and develop my SketchUp Rubies. -

Ruby Toolbar started - on Windows, it can open/close the Ruby Console, Clear it, and load/reload a file.

You need WIn32API.so

I have written a debugger for Sketchup plugins with watches and breakpoints. Why isn't such a debugger already available? Would it be a good contribution to the community? The breakpoints based on watched variable changes seem like the best part.
Download the user guide that I attached.
It needs some work yet, as it processes only the Ruby snytax that I have
programmed with myself. It is a VB6 app. It would be free.Quote message
Face2Face plugin - autoextrusion between faces

by brian_concannonTIG,
I posted the plugin as you suggested, in the Resources/Plugins forum. It is being downloaded like crazy!
I hope you make it part of your Edgedraw plugins somehow.
anyway, I have written a debugger for Sketchup plugins with watches and breakpoints. Why isn't such a debugger already available? Would it be a good contribution to the community?

From: TIG
To: brian_concannonIt would probably be a useful adjunct.
Why not post in the Developers' forum with a new thread.
You don't need to post the whole of your code, just some ideas to get a discussion rolling...
Thomthom, Jim and Dan are more in debugging etc than I am. I manually slog through with my own return nils, breaks, testing puts, UI.messageboxe, refreshes etc till I get it to work

That's my method of debugging as well. A debugger would be welcome. There is one out there already SuRDebug: http://code.google.com/p/surdebug/wiki/SuRDebug
I never got around to fully make it work...

I tried SurDebug early on and could not make it work either. I was told that the author got angry about some criticism, and he stopped working on it. There were no recent posts about it at the site that you show.
Debuggifier's concept is not as nice as the SurDebug concept, as it inserts debug statements after every Ruby statement in all or part of the code. It can be commented / uncommented at will, and totally removed ("undebuggified") when the Plugin development is complete. But I found it necessary to develop for my own programming, because Ruby is so hard to program with. Anyone using a true IDE knows this.
I will clean up Debuggifier a little and then post it. Since it is an EXE and requires VB6 DLL's to be installed with InstallShield etc, can I upload it to this forum? Can I upload a zip file?

There's a 4mb limit and it'll will need to be .zip
