SU ruby questions part2

sepultribe

Hello once again. I'm confused about how to load ruby gems like savon or yaml from an external ruby 2.0 installation in sketchup 2014 M1. Is the $LOAD_PATH method and interpreter dll copying still needed like in older SU with ruby 1.8.7?

Also, I saw a recommended template for ruby scripts wrapping the plugin inside a module and a singleton class. I understand the module creating a unique namespace so as not to clash with anything else, but what is the use of the singleton class?

thanks

One question per thread, please. Let's talk about gems in this one.

..., but I think it's either that way (installing all required gem files inside your sketchup or plugin folder) or using an external ruby installation which will be the same version as your sketchup ruby version and editing the $LOAD_PATH variable to include that location.

The second was true for the old SketchUp versions that used 1.8.x Ruby.

Neither method is true any longer since SketchUp 2014. The Ruby Standard Library is now distributed with SketchUp. (It is beneath the "Tools" directory.)

RubyGems is now distributed with Ruby 2.x.
Pure ruby gems (or precompiled gems) can be installed under SketchUp. The gems folder where they are installed, is in the User %(#000000)[%AppData%] path.

32-bit SketchUp w/ 32-bit Ruby 2.0:
" %AppData%\SketchUp\SketchUp 2014\SketchUp\Gems"
or:
" %AppData%\SketchUp\SketchUp 2015\SketchUp\Gems"

64-bit SketchUp 2015 w/ 64-bit Ruby 2.0:
" %AppData%\SketchUp\SketchUp 2015\SketchUp\Gems64"

Use something like:
require "gemname" rescue Gem::install "gemname"
or

retried = false
begin
  require "gemname"
rescue LoadError
  Gem;;install "gemname"
  if !retried
    retried = true
    retry
  end
end

yaml is an easy one because it is part of the Standard Library now included with SketchUp 2014 or higher.

Just require it:
require "yaml"

Now in SketchUp 2015 64bit, I got no errors at the console with:
Gem::install "savon"

... which returned an array (of these gem specifications that were installed):

[
  #<Gem;;Specification;0x9619f3c nori-2.6.0>,
  #<Gem;;Specification;0x97050b8 rack-1.6.4>,
  #<Gem;;Specification;0x77ac360 httpi-2.4.1>,
  #<Gem;;Specification;0x6cba77c mini_portile-0.6.2>,
  #<Gem;;Specification;0x5471878 nokogiri-1.6.6.2-x64-mingw32>,

  #<Gem;;Specification;0x77e0200 akami-1.3.1>,
  #<Gem;;Specification;0x5626f88 savon-2.11.1>
]

.. afterward: require "savon"
returned true

thats what I get in SU2014 M1... not sure what they changed and it succeeds on 2015.

EDIT: failed on latest 2015 (x86) version too. I'm on w7 x64 don't know if that's the issue...

EDIT2: appended external ruby 2.0 paths to $LOAD_PATH (which has savon installed) and can't require or install savon still. this is very frustrating... Also tried pasting nokogiri.so to PLUGIN folder, to TOOLS folder, and several others with no success...

EDIT3: installed devkit to ruby 2.0 external installation and added main directory to load_path but still no success.

went here ~> http://www.nokogiri.org/tutorials/installing_nokogiri.html#windows

pasted this gem file into ..\AppData\Roaming\SketchUp\SketchUp 2015\SketchUp\Gems32\cache directory, renamed it to nokogiri-1.6.6.2.gem which is what sketchup is downloading and it managed to install at first glance.

then I do this

require 'savon'
Error; #<Gem;;LoadError; Could not find 'nokogiri' (>= 1.4.2) - did find; [nokogiri-1.6.5-x86-mingw32]>

I'm pulling my hair as I really need this to finish a project for school.

Try the 32-bit sketchup if you are not already using it.

I use the 32-bit version of Ruby on my 64-bit Wondows because some gems just do not work when I tried. Nokogiri was one of them.

I only used x86 versions of sketchup for my testing, as I need my plugin to work on old xp machines at school. I'm really curious how Dan managed to do it so easily on a 64-bit version of sketchup... I must be so unlucky. I'll try to install a x64 SU now and see if there's any luck...

edit: confirm 64 bit SU15 doesnt throw error on savon install, BUT when I try to use it

The last error is the result of the quirky implementation of Sketchup::Console class. (It is not a subclass of IO, but should have been.)

Try some other way of testing your results.
UI.messagebox or a webdialog.
