1.8.5

(RUBY_PATCHLEVEL gives an error)

because Sketchup is loading 1.8.5 initial (p0)

The RUBY_PATCHLEVEL constant was introduced in p12.

i don't think ruby comes with sketchup as it's part of os x but...

I know OSX comes with Ruby, but what version & patchlevel ?

Can you open a bash shell and start Ruby or IRB and enter the constants again, please?

jeff hammond

that's pretty much chinese to me (and i speak/read zero chinese).. but if i type ruby -v in terminal i get:

ruby 1.8.7 (2009-06-12 patchlevel 174) [universal-darwin10.0]

(the earlier 1.8.5 output was given to me when typing the constants in the su ruby window)

Dan Rathbun

Thanks Jeff ... that'll do.

It shows that Sketchup is loading it's own copy of the Ruby interpreter (which is obsolete, by the way. The entire 1.8.5 branch has been "retired" and is no longer being updated.) SU Mac still is running the initial release of a dead Ruby branch!

There is a symbolic link in the SU app folders (somewhere,) pointing at the old Ruby in the Ruby.Frameworks/Versions/A

I don't have a Mac.. but there must be a way for you guys to point that link at your up to date "system" Ruby.

%(#0040FF)[...$ ruby -v
ruby 1.8.6 (2009-06-08 patchlevel 369) [universal-darwin9.0]]
and on OSX 10.5.8, I've got a different version to Jeff

Did you do that from SketchUp's ruby console, or from OSX's command console?

Terminal,

trying to work out how to point SU at that one at least...

what version is used on PC SU now?

the path to version 8.5

/Applications/Google\ SketchUp\ 8/SketchUp.app/Contents/Frameworks/Ruby.framework/Versions/A/Ruby

but how to point it to system version??

I recently updated everything to snow leopard so I guess apple has the latest ruby in there.

Another question for Apple MRI Ruby .. how does a Mac owner update there Ruby ?

Does their "system" Ruby come with RubyGems preinstalled ?
Or do they need to go to an Apple website to download a Ruby update?

check the Apple Help website on using, creating and editing symbolic links.

If you figure out how to do it.. post a "How To" here at SCF.
(Suggest if possible to back up the old symbolic link, before changing it.)

Sketchup 8.0 M0 and M1 come "out-of-the-box" with v1.8.6-p287, but it is very easy to change that on PC by replacing the DLL (as long as it's in the 1.8 trunk.)

i want to extend the build_in sketchup interpreter too.
from the release note post by google here http://cfcl.com/twiki/bin/view/Projects/SketchUp/RE_Library_Use
Su 8.0 on pc has a 1.8.6 and a 1.8.5 on mac
the new 8.0 M1 release note says nothing about the ruby version. so i assume it is still the same.
here http://cfcl.com/twiki/bin/view/Projects/SketchUp/RE_Library_Use
Main.RichMorin post sth interesting. He also try to extend ruby inside su to other parts of the library, gems, etc.
it semms that he hasn't work it out yet.
but it's worth a try.
and i hope some gurus follow this path and somebody find a way eventually
note that even on pc it is 1.8.6 all right, but it has very limited access to the standard library and gems.
i try to use CSV class, but it fails.

Thanks again! Dan!
you are a very good helper. and fast.
you have showed me this load path code before. i just couldn't understand it fully then. now with more ruby reading, it all make sense to me.
it feels great to be in a such nice community.
i will keep read on.

Not for the faint of heart, but here's how:

quit sketchup
open a terminal window
cd /Applications/Google\ SketchUp \8/SketchUp.app/Contents/Frameworks/Ruby.framework/Versions
sudo mv A A.orig
sudo ln -s /System/Library/Frameworks/Ruby.framework/Versions/1.8 A

Restart SketchUp, open a Console window, and type VERSION. If all went well, it should report the same version as when you type ruby -e "puts VERSION" in a console window.

To undo this hack, in the same Versions folder:

sudo rm A
sudo mv A.orig A

Hi Steve,
I run as an admin, but not root, I need sudo for anything outside user space.
'Content' folders should have User read/write permissions, I thought.
I also run multiple copies of SU, the path for this one differs from norm and yours. [that may be the splat]

the other thing I have now added sleep 1 and a return before the cd / to reopen SU in both methods.

I may have done blanket permission change using Sketchup.app >> right click >> more info and change for all enclosed files, but I don't think so... but that should work to avoid 'sudo'.
alternatively do that to your 'User' folder after installing SU there?

just using the bits needed for a restart seems handy as well.

@John: The global constant VERSION is deprecated because every class and module should have one that specifies it's version, but if the global is defined, it will get inherited into every class and module, and it's easy to assume the inherited one is a specific module version.

Example at the console:
module Dan; end %(#008000)[>> nil] Dan.module_eval("VERSION") %(#008000)[>> 1.8.6]

Oh look, module Dan is version 1.8.6 ?

Not really:
Dan::VERSION %(#008000)[>> Error: #<NameError: (eval): uninitialized constant Dan::VERSION> (eval)]

Use RUBY_VERSION instead. (As well as the other constants that are prefixed RUBY_ ... please.)

@Steve: Please don't quote codeblocks. Besides wasting space (and SCF bandwidth,) it just clones errors, and the original poster of the code may make corrections to the code, which will not be propagated into your quote. (I wish the quote feature would auto-strip them and insert a link back to the quoted post.)

(pssst... you can edit your post and delete the quoted code.)

Hi Steve,
just got back and tested your method, works a treat, so I worked out a Ruby Console 'none sudo' version that works here, if it works for you I'll make it into a toggle button for switching from inside SU...

yes Dan I'll wrap it in a module...

Hi John,

On my Mac, the folders and files involved all have root ownership and rwxr-xr-x permissions, so without sudo I could change nothing. When I tried this script, SketchUp crashed (no bugsplat, just vanished!), and nothing changed. You aren't running as root are you? I can see how, after changing permissions, your script would be useful for toggling back and forth between versions, but I don't understand how it can work without either that tweak or sudo?

Steve

P.S. OK Dan, I deleted the code block

Hmm...there is a school of though that says ordinary users shouldn't be able to tamper within the subfolders of an app bundle, since they can destabilize the app in arbitrary ways. I once ran a utility that "fixes problems due to permissions", and I wonder if it reset the SU folders and files based on that thinking? Horse is out of the barn now, so without removing and reinstalling SU it's impossible for me to be sure. Maybe if another Mac user is watching this, they can look at their folders before either of our tweaks and tell us what permissions they see? The answer would be important so that your script could be shared successfully.

On a more basic level, after switching to 1.8.7, why would someone want to switch back? The only reason I have thought of is if you are writing plugins for the general Mac community, you might want to verify that they run on the as-installed SU with 1.8.5. So far, I haven't run into any old ones that won't run on 1.8.7. And if I do, provided they were distributed as open code, I'd be more inclined to fix them than to switch back to 1.8.5 just for their sake!

I had seen the problem Dan cites when I used the new Ruby console the Trimble guys posted on GitHub - VERSION on it returns 0.0.1; you have to use RUBY_VERSION to get the right string.
