      Using WinDowse I could change the Ruby Console text output.

      So I was wondering - one should be able to do that using Win32 API calls.
      But I'm not so experienced with the Win32 API.

      How would you:
      Get the active Ruby Console window?
      I guess one can make the command work only from the console. So the method would get the handle for the currently active foreground window and check that it's title is "Ruby Console".
      ?

      How do you get the handles for the correct textbox?

      How do you change its text properties.

        last time when I checked it didn't help much because the whole text will be back on the print/puts

          Have you looked at Jim's plugin that doe this? I don't know about the prints/puts thing though. His plugin only works in 32bit, so it never quite worked for me. 😞

              So this means SU caches ALL the text? it doesn't append to the existing text, to completely rewrites it?? No wonder that thing is slow!

                looking at this again:

                After using WinDowse to clear the text:

                • if I click the command line textbox in the Ruby Console to bring up any old commands - then all the old stuff comes back
                • if I don't do that - and use a script that uses a puts statement - or type in a new command or blank line into the Ruby Console command line - then the old history doesn't come back any more.

                  The Ruby console "As Is" needs to die a torturous and horrible death, and in its place, a new multi-line console "shining prince" (not IO! πŸ˜‰ ) would herald in the new era of scripting bliss!

                  Always sleep with a loaded gun under your pillow!

                    After you have cleared the console why not have your code do an empty puts to help you ?

                      well - I have not written the code yet. I've only used WinDowse to poke about.
                      But yes - that would be a solution - if I now could work out how to do this from Ruby.

                        I have PM'd you clearConsole.rb that works OK - I didn't publish it here as I'm unsure where it came from - no accreditation in the header ?
                        ❓

                            morisdov compiled a small windows exe to clear the console. It is called using the system command. I use it, and like to have it around because I can also double-click it from my file manager and clear the console.

                            (I was sure this was posted at morsidov's site, but it does not seem to be available now.)

                              Here is a routine which should work.

                              If you have problems, let me know.
                              (Sometimes code I extract from larger projects only works because of other plugins I have loaded already)

                              • Place Win32API.so in the Plugins folder (I grabbed a copy from the ruby install and placed it there)
                              • place clear_ruby_console.rb in your Plugins folder.
                              • "Clear Ruby Console" should appear at the bottom of the Window drop-down menu after you start SketchUp

                              clear_ruby_console.rb

                              clear_ruby_console.rb

                              
                              # you need Win32API.so in the Plugins folder for this to work.
                              # I grabbed a copy from the ruby install and placed it there
                              require 'Win32API'

                                Thanks, it works! And I learned something new (win32api calls) with this example of yours. Thanks!
                                Yet, be careful there... I am sure you know about this but, in ruby only "false" and "nil" evaluate to "false", "C language" NULL does not, so you need to test against 0(zero) instead of using the "not operator" on the return values, which are numbers and therefore using "not" always yield to false in ruby.

                                  Clears input and output windows. Toggle output off and on to clear just output.
