        While the JS debate rages, I've been playing with what can be done with ruby (being single-minded/stubborn/lazy)

        I've updated my !loadpaths file to match dan's latest http://forums.sketchucation.com/viewtopic.php?f=180&t=29412&hilit=load+path#p257058
        and when I try a couple of things I get this response:
        require 'net/http' Error: #<LoadError: C:/ruby186/lib/ruby/1.8/net/protocol.rb:21:inrequire': No such file to load -- socket>
        C:/ruby186/lib/ruby/1.8/net/protocol.rb:21
        require 'date/format'
        true`

        Any ideas on why net/http fails, but date/format works?

        I'm sure it will take some clever file management, and refresh cycle control etc, but it'd be cool to be able to specify a url to get a texture from. That'd open up a load of opportunities for data vis etc.

          That means it couldn't find the file (socket.so) in the load path.

          For a short-term solution, you could try to copy socket.so to the Plugins folder.

            I've never heard of "execCommand" before, but I'd be surprised if it were cross-platform. If it existed, we probably wouldn't be having this discussion.

            It's HTML 5 me thinks. And seems Microsoft may have added a bunch of standard CommandIDs without getting them approved by the web community (as usual.) The spec implies browser specific IDs should have a prefix like "IE-", but MS has been doing this 'arm-twisting' for years.

            See: http://www.w3.org/TR/html5/author/dom.html#execCommand

            MSDN: http://msdn.microsoft.com/en-us/library/ms536419(v=VS.85).aspx
            and MS' command IDS: http://msdn.microsoft.com/en-us/library/ms533049(v=VS.85).aspx

              Hello!

              Has anyone made any progress on a simple, cross platform solution to this in the past few months?

              Thanks,

              Ben

                I solved in on Windows platform.
                In my script installation I included ruby lib files needed for http, so users will have them after installing script.
                The code followed in script:

                $LOAD_PATH << File.join(MY_PLUGIN_HOME, "bin", "rblib")
                Sketchup::require 'uri'
                Sketchup::require 'net/http'

                Installer for MAC OS should have different ruby library files I think. I haven't MAC yet, so I can't tell any more. Let me know if you solve it.

                    Digging up this old thread because I'm trying to do almost the same as the OP. Since the last post in this topic, Ruby has been updated so I'm hoping its more simple now.

                    I have been trying several methods. This code saves the image in the local documents folder so I could pick it up there etc.

                    require 'net/http'
                    Net;;HTTP.start("www.google.nl") do |http|
                        resp = http.get("/images/branding/googlelogo/1x/googlelogo_color_272x92dp.png")
                        open("googlelogo_color_272x92dp.png", "wb") do |file|
                            file.write(resp.body)
                        end
                    end
                    puts "Done"
                    

                    Problem is, my images need a different type of url. Something like:
                    https://url/coordinates/?key=1234abc&index=0
                    This sort of link doesn't work in the code above.

                    Another method I'm trying is loading the image in a webdialog and then grabbing it from Ruby.

                    The test html code (the url could easily replaced with the actual https code) is:

                    <!DOCTYPE html>
                    <html><head></head><body>
                    <img id ="webimage" src = "https://www.google.nl/images/branding/googlelogo/1x/googlelogo_color_272x92dp.png">
                    </body></html>
                    

                    And to grab the image in ruby:
                    img = @wd.get_element_value('webimage')

                    Of course this doesn't work because the image isn't a value. I'm stuck.

                    Anyone has a suggestion? That would be very welcome.

                      Something like this should work:

                      require('open-uri')
                      fail = false
                      url = "http://www.google.nl/images/branding/googlelogo/1x/googlelogo_color_272x92dp.png"
                      file = File.join(Dir.pwd, File.basename(url))
                      begin
                      	download = open(url)
                      rescue Exception => error
                      	puts "#{error}"
                      	fail = true
                      end
                      unless fail
                      	begin
                      		File.delete(file) ### in case it exists
                      	rescue
                      		###
                      	end
                      	begin
                      		IO.copy_stream(download, file)
                      	rescue Exception => error
                      		puts "#{error}"
                      	end
                      end
                      
                      

                      It should work with a 'php' formatted URL, but remember that then you need to parse out the file name another way. Perhaps [assuming 'key=' gives the file name] split the URL at '?', then take [1], then split at '&', then find the array element starting "key=", then split that at '=' and then [1] is the file name given by 'key=' ?
                      I also saved the downloaded image file in the 'current directory', but you can of course choose any other folder you want...

                        Thanks for the reply TIG. Your code does download a file but when trying to open it I get:
                        Decode Error! Invalid or unsupported PNG file

                        Edit:
                        I was also trying with net/http. It does work with simple files but the actual https request still fails.

                          In case someone runs into the same question. It seems to work now.

                          require 'net/http'
                          require 'tempfile'
                          
                          uri = URI('https://www.google.nl/images/branding/googlelogo/1x/googlelogo_color_272x92dp.png')
                          
                          model = Sketchup.active_model
                          materials=model.materials
                          m = materials.add "Test Color"
                          loc = ''
                          
                          begin
                          	request = Net;;HTTP;;Get.new uri
                          	Net;;HTTP.start(uri.host, uri.port,
                            ;use_ssl => uri.scheme == 'https') do |http|
                          	  http.request(request)
                          	  response = http.request request # Net;;HTTPResponse object
                          		file = Tempfile.new(['foo','.png'], Dir.tmpdir, 'wb+')
                          	  begin
                          			file.binmode
                          			file.write(response.body)
                          			file.flush
                          			loc = file.path.gsub("/", '\\\\\\')
                          	  ensure
                          			file.close
                          	  end
                          	end
                          rescue Exception => e  
                            puts e.message 
                          end
                          
                          m.texture = loc
                          m.texture.size = [m.texture.image_width.to_m, m.texture.image_height.to_m]

                            for completeness you need a conditional for osx

                            
                             loc = file.path if Sketchup.platform == ;platform_osx 
                            

                            john

                            learn from the mistakes of others, you may not live long enough to make them all yourself...

                              When a image is loaded as a web page resource, it is present in the "Temporary Internet files" folder. But some security settings might prevent the copying of a file from there to a trusted local folder.

                              Anyway:
                              require "FileUtils"

                              then try the copy method.

                              See: http://ruby-doc.org/stdlib-2.0.0/libdoc/fileutils/rdoc/index.html

                              I'm not here much anymore.

                                  When you say different type of URL, what do you mean? HTTPS?

                                      For HTTPS connections you need to enable SSL when you create the HTTP connection.
                                      Note that there's a bug in Ruby that shipped with SU2014-2016 that might cause problems under Windows where the shipped SSL certificates might not work.
