Ruby Version for Sketchup 8.0 M1 on Mac ??

Dan Rathbun

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.

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.

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??

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...

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.

I've never considered myself ordinary maybe ornery root and admin read/write same for V8 on my wife's machine

I was thinking that this would be more for Dev's and/or the curious, and if you add an -n flag, to the open cmd you can have both at once in two separate instances of Sketchup.

Well, oddly enough the code I first had for this, would only work from 1.8.5 >> 1.8.7 but not back down.
It took me ages to find the same layout that would work in both Thread.new requires a block in 1.8.7, but will work in 1.8.5 with or without.

From the Ruby v1.8.6-p398 API Core Reference, for Object constants:

The caption "obsolete constants" is supposed to be in a right margin, but the DarkFish doc generator didn't do that. It shoved the right margin text under the first item in the left column.

A check of the online doc for v1.9.x shows they have finally been removed.
see: Ruby Core v1.9.3: Object

slbaumgartner

Dan,

I find those parts of the Ruby documentation ambiguous, as the phrase "obsolete constants" displays below VERSION when I view the page, as if, in the example you posted, it applies to RELEASE_DATE and PLATFORM but not to VERSION. In any case, it is clear that we should use RUBY_VERSION as there are examples on the table where using VERSION breaks

so, you need to double escape the system path, but single escape the ruby one.... aaahhhhhh

ok,

I've got a button version that works fine on one of my SU.app install paths but not the other, even this basic excerpt won't work

the only difference is the path
what does returning **1** as opposed to **#<Thread:0x12cd6f4c sleep>**

help.... SOLVED, it is odd how posting helps

Ah the joy of escapes! You need one \ to preserve the space in a path used by Ruby itself, but \ to pass along \ to preserve the space when the path will be sent to the system. Ack!!

I'll be tied up for a day or two with holiday obligations, but will be glad to try this out when I get some free time.

I found a new trick if you have @apPath=("/Applications/Google\ SketchUp\ 8/SketchUp.app") you can use it as ruby @apPath.to_s etc... or wrap it for a system call like this
(open -n $"#{@apPath}"\n)
I think that's very handy, john

slbaumgartner

@driven said:

Still not wrapped, as I think I'll add it to my ON_OFF.rb and rework that to add a few new tricks this exercise has exposed.
However, this is now running in either of the two versions of SU I have installed at different Paths, and it should also add your native Ruby and Gem Paths on >1.8.5 [gems don't work on 1.8.5 unless you still have a full instal of both...]
[attachment=0:28ht225z]rubyVersion_change.rb[/attachment:28ht225z]
Should I delete all the other progression code? I did edit it to work, and it has a variety of other methods...

John,

Lots of problems with this code on my Mac. I'm pressed for time right now, will PM you later when I get a chance.

There's 2 potential problems I can see, the first is my need to check which version of SUv8 I'm using, as they share .plist, so I've re-coded all that and this should return the correct path regardless of version.
Works without the hard coded version numbers on mine.
If it does you could just swop it in and test further, or let me know.


@SUversion=(Sketchup.version.to_s)
stndSU=("/Applications/Google\ SketchUp\ 8/SketchUp.app")
altSU=("/Applications/SketchUp.app")
chkSU=("/Applications/Sketchup.app/Contents/Info.plist")
if File.exists? chkSU
f=(IO.readlines chkSU)
k=(f.index "\t<key>CFBundleVersion</key>\n").to_i
v=(k + 1)
s=(f[v]).gsub("<string>","").gsub("</string>","").strip
end
if s === @SUversion
@apPath=(altSU)
else
@apPath=(stndSU)
end #if
@apPath.freeze
@verPath=("/Contents/Frameworks/Ruby.framework/Versions")
@ourPath=(@apPath.to_s + @verPath.to_s)

The second problem could be your permissions, which I can't check easily, but I could have a conditional that fails gracefully.
john
added @SUversion=(Sketchup.version.to_s) as first line so this should run as a standalone, it's already in the ruby...

slbaumgartner

Update to the community: driven and I have got a plugin to do this Ruby swap nearly ready. Currently kicking it around to shake out any remaining bugs and packaging it for distribution. We'll put in the plugins forum soon.

Just playin' devil's advocate:

Must the switch be done from within SketchUp, requiring a restart... or can desktop shortcuts (aka symbolic links, for you unix-like peeps,) be created to start SketchUp running whatever Ruby version is desired ?

(I had asked this question long ago, in a similar topic thread.)
