[Plugin] Material_Maintenance v2.2 - 2013-01-13

[cmd]

Here is the output from the ruby console after replacing with your posted Material_Maintenance.rb and launching the tool.

You may need to move the method definition of fromUIHandler to after the definition of refreshMaterials. Ruby might be trying to call refreshMaterials

  ` results = self.send(targetFunction.to_sym, *params)`

before it is defined.

I sent a PM.

Thanks CMD.

Unfortunately the attached output implies that the debug version of the Material_Maintenance.rb script did not run but rather the old version.

the error says:

Error; #<NoMethodError; undefined method `refreshMaterials' for #<MH_KeepingMyHandIn;;MaterialMaintenance;0x1383e920>>
/Library/Application Support/Google SketchUp 8/SketchUp/Plugins/Material_Maintenance/Material_Maintenance.rb;106;in `send'

and indicates the send method call is on line 106, while it is actually on line 122 in the debug version.

Have you restarted Sketchup after copying the new file in?

A few ways to check that the debug script is running are:

• You should see this message in the console: "calling function >>refreshMaterials<<"; There might also be the same message but with other function names
• The the above error appears again, it should be on line 122 not line 106.

Cheers,

sorry about that.

Unfortunately, here is what I get with your debug .rb

I get this with ruby 1.8.5 or ruby 1.8.7

Myhand,

Sorry.. I replaced the wrong file. Here is what I get in the Ruby console with your debug script after I launch the tool.

String Time = 3.0e-06

I hope this helps

what version of ruby are you running?

I only see that encoded  if I run 1.8.7 on the original file...

I was actually wondering if it was an encoding issue as the script is not UFT8 out of the box. and uses chars that maybe misrepresented on macs

Excellent this helps a lot. It tells us that somewhere the function name gets corrupted between where it is hardcoded in the javascript to where it enters the Ruby environment.

Was that the whole output? Were there no other lines following the below patterns? I would have expected at least one more set, probably before the above lines.

calling function >>xxxx<<
!!!!! - IN xxxx !!!!!

Where xxxx is any name.

I suspect driven might be correct. Let me give this some thought.

I'm having such a great month upgrading my Sketchup! Artisan, SketchUV, ProfileBuilder Pro, 1001Bits, and now this VERY useful plugin.

Managing materials was always a major headache for me, especially when building multi-story houses with downloaded furniture. I tend to forget the fact that the downloaded furniture may have some of the same materials I assigned to what I already have in the model. I once waited for a long KT render to find out the pillows on one of the beds were made of chrome. This looks like it will save me a lot of material scanning time before export.

CMD, here is the next iteration of the debug script. It might fix the problem as I have changed the way I specify the special characters I use from literals to providing the actual character codes. Even though they are special they are extended ascii so should work fine. As the .js file is UTF8 encoded I have not changed how I specify the chars there yet, but again it might just work.

Either way I have also added extra trace code, so if it does not work it will give us further info to help pin down the problem.

Do you mind trying it out and sending me the output again? Same procedure as before, just replace the .rb file with the attached version.

they are not the same as the original chars, I was seeing in my script editor, and the script is now saying it's encoded uft8, which it wasn't

You are returning a string divided up with some unique character.
You then parse that string into bits, splitting it with that character.
Unfortunately that character seems not to be a simple 1 bit ASCII character when passed over, so the split ends with the weird extra character that's left over at the end.
This causes the issue.
MAC and PC Ruby are different in the way they handle text-encoding...
Are your various files encoded as ' UTF-8 without BOM' ?
If you have Notepad++ it's a simple setting.
This makes files 'cross-platform' [hopefully!].
AND/or can you use a less 'exotic' dividing character - perhaps '|' ?

TIG, I think your description is spot-on. I have now encoded the attached version of the file with UTF-8 without BOM (yes I use Notepad++ ) The JS file is already was already encoded in the that format.

I would not have thought that the ruby file encoding should make a difference anymore as I am now explicitly setting the character codes (which are in the ascii range) I suspect JS is passing the character in as UTF-8. The reason for the exotic chars is that Sketchup does not seem to constrain chars users can enter in material names so in theory you can get conflict in the lower ascii range.

I should probably write the simple JSON parser to complement my simple JSON serializer and get rid of the current char token approach in my bridge.

driven, cmd, can you test again please?

Hi John, these are the actual char codes, I have not changed the JS side and these codes still work for me on windows.

I will now also change them in JS to explicit ASCII values. Unfortunately I have to repackage the whole plugin then, so will take me a bit of time, but then again it is likely to work.

[thomthom]

SketchUp return strings in UTF-8. Anything above the ASCII character range will be multi-byte characters - which is easily mangled by Ruby 1.8's string manipulation methods as it treats 'characters' as single bytes.

But my characters are well within the ASCII range...? i.e. they still fit within a byte. from which value does it convert them to multi byte?

[Myhand]

Ok so here is a debug version with the the token chars explicitly specified in both JS and Ruby. Unfortunately you will have to un-install the whole plugin and install the debug version.

It still has tracing code in, so will still be a bit slow.

John, CMD can you test again please?
