Have you got deBabelizer.rb in the Plugins Folder ? :?

Hi Tig,

I only installed it to send you a report from another Mac, and am sure I used all of the correct instal procedures.

your other tools are still working (EEby.., Manifold, Vol..2) , after the CofG_1.2 instal (including deBalelizer.rb)

after the first (_1.2) Error, I replaced both files with the _1.1 files and had the same error.

I then tested all in the same drawing
EEby Rail--worked
Volume2 --worked
Manifold --worked
CofG --same error report (-1.2 re-installed from zip)

A mystery...


def CofGravity;;calculate ### LINE 129 ==start of class/def that is reporting the error...

def db(string)
  dir=File.dirname(__FILE__)+"/TIGtools"
  toolname="CofGravity" 
  locale=Sketchup.get_locale.upcase
  path=dir+"/"+toolname+locale+".lingvo"
  if not File.exist?(path)
    return string
  else
    deBabelizer(string,path)
  end 
end#db

if (Sketchup.version.split(".")[0].to_i<5)
     UI.messagebox(db("C of G; Sorry, this is Version >= 6 Tool !"))
     return nil
end#if

model=Sketchup.active_model
entities=model.active_entities

############
if Sketchup.version[0,1].to_i > 6
  model.start_operation((db("C of G")),true)### LINE 153 GIVES ERROR !!!

Can you look at the script's contents and see if it looks like this ?
Works fine on a PC for me - can't see where a Mac might trip up ?

Jim

Need to require 'dBabelizer' before you use it.

TIG

Jim

That's it ! Thanks.

Other tools requiring it were masking the fact I missed it out of the initial 'require'...

Update on it's way !!!

driven

that appears exactly the same,
the only thing that seems at odds is the syntax colouring for calculate shows it as a variable??
I don't know enough to know why, or where to look next

this is odd...

I'll send this even if the missing "require" is at fault, because I don't understand why one and not the other would be a variable....

TIG

Here's v1.3...
http://forums.sketchucation.com/viewtopic.php?p=229404#p229404
The initial 'require' of deBabelizer was accidentally missed out, but its absence was masked by some other tools loading it anyway so most times it worked anyway...
Now it is explicitly called for in the tool...
Sorry for the confusion...

driven

Same error code, same syntax colouring for line 813

seems to have something to do with it...

TIG

driven

Have you got the recent v1.3, with the require 'deBabelizer.rb' added ?
This should fix it ?

TIG

If calculate is a reserved term in Mac Ruby versus PC I'm surprised...
You can edit the file and change every ' calculate' to say ' do_calculation' and see if that helps - if so let me know asap

driven

Yes it's v1.3

changed to tig_calculate (lines 131, 815)

Error; #<NoMethodError; undefined method `db' for CofGravity;Class>
/Library/Application Support/Google SketchUp 7/SketchUp/Plugins/CofGravity.rb;155;in `calculate'
/Library/Application Support/Google SketchUp 7/SketchUp/Plugins/CofGravity.rb;815

but the colour changed

You mustn't have changed them all as it's still calling 'calculate' ?
I've redone the original and v1.4 with full 'do_calculation' will be there asap...

TIG

Here's v1.4 http://forums.sketchucation.com/viewtopic.php?p=229401#p229401 with 'calculate' replaced with 'do_calculation' to see if that fixes it - if not I have exhausted all ideas so far !!!

driven

Ok, v1.4

Error; #<NoMethodError; undefined method `db' for CofGravity;Class>
/Library/Application Support/Google SketchUp 7/SketchUp/Plugins/CofGravity.rb;156;in `do_calculation'
/Library/Application Support/Google SketchUp 7/SketchUp/Plugins/CofGravity.rb;816

sorry

...Any more ideas welcome...

Not yet, TIG - at least not anything that would be clear. I was just thinking aloud and combining my ideas. Maybe when I have already used the plugin for such things.

Thanks anyway!

TIG

Aaaarrrgh...
BUT as we can all see it is defining db as a method inside the particular class::def and then using it - the way it's used loads of times in other tools too... It works fine on PC so what is so special about a Mac ?
Puzzled... Any Mac scripters have any ideas ???

driven

it is in the db method,

I just ran composite on to groups and got this

Error; #<NoMethodError; undefined method `db' for CofGravity;Class>
/Library/Application Support/Google SketchUp 7/SketchUp/Plugins/CofGravity.rb;604;in `composite'
/Library/Application Support/Google SketchUp 7/SketchUp/Plugins/CofGravity.rb;817

TIG,

Sorry for the earlier abbreviated message - I got called away from the computer.

I get the following when trying CofG (Version 1.4 here).

Error: #<NoMethodError: undefined method db' for CofGravity:Class> /Library/Application Support/Google SketchUp 7/SketchUp/Plugins/CofGravity.rb:156:in do_calculation'

Possibly something to do with the version of Ruby? Macs running Snow Leopard come with a pre-packaged version 1.8.7 of Ruby.

TIG

The error is with the db def method... BUT it ha been and is still working fine on PCs and it's been used in similar ways in many other tools... so why the problem here ?
To avoid having to add deBabelizer(string, lingvo_file_path) to every string in the output that needs translating I make a shortcut method def db for each tool
that alls deBabelizer and has the lingvo_file_path hardcoded into it, and works simply as db(string).
It's easy and effective in all my recent tools, so why the problem here ???
It's clear now that it wasn't the missed out 'require' or other possible clashes that were causing this... BUT why it's not working is a mystery...

Surely you can call a def inside another def though ??? even with 1.8.7 on Macs ???

I had checked for any evidence of Vista stupidity given past experience with having to look at the Virtual Store. But I've tried v. 1.4 and it works great!

Thank you so much for your incredible plugins. I'm using them for sci-fi mesh analysis and they are invaluable.
