Automaticaly try to import files that aren't .sku

Jim · 19 Oct 2009, 15:37

Yes, the environment variables are stored in a hash named ENV. Just type ENV in the Ruby Console:


ENV # View the entire hash
ENV["TheKey"] # returns a value
ENV["TheKey'] = nil # setting a value

I was thinking the ruby could live permenent;y in the Plugins foder, and just check for the existence of and env variable. If it is set, do to import (perhaps using a messagebox to confirm.) after everything finishes loading.

Jim could you expand on what you are saying some?

Are you saying the a Windows Environment variable can be read by ruby in sketchup?
If so can it be set to nil when the ruby script is done importing the DWG?

I guess I envision something like the following pseudo-code


> If EnvVar != nil then
>   import EnvVar
>   set EnvVar = nil
> end if

That would be a better idea than creating and destroying a hard coded script file as my program currently does.

Cool Beans Jim.

Of course it doesn't solve requiring my app to be running all the time. I suppose I could make it so it always stays on top but that could get to be annoying.

Dropping the DWG file on the taskbar icon doesn't Drop the file. Instead it make the application you dropped on the active application (So you have to drop a second time)

Can a web form detect a DragDrop event? If so perhaps a small always running web form would a better route? At least you could then import Acad files while SketchUp was running.

Don't know diddly about web apps so I am out of my element there.

Great thought, and I'd bet the file path would then be accessible in the dialog and then could passed to Ruby, but I don't know enough about it to even test it.

update: dropping a file onto a dialog does indeed trigger some event. In my test case a Ruby file was dropped on a webdialog, and i was then presented the opportunity to save the file. I'm not sure if/how that could be trapped in JavaScript.

Dropping a text file displayed the file in the dialog.

up-update - couldn't be as simple as an ondrop function?

Jim · 20 Oct 2009, 01:52

Here's an example for using the ondrop. I do not know how to get the dropped file name.

(I really wish this Ruby syntax would work:)


@dropper_dlg = UI;;WebDialog.new
@dropper_dlg.set_html(DATA.read)
@dropper_dlg.add_action_callback("drop") { |d, a|
  puts "drop;#{a.inspect}"
}
@dropper_dlg.show

__END__
<html>
  <head>
    <script>
      function drop() {
        window.location="skp;drop";
      }
      function cancelEvent() {
        window.event.returnValue = false;
      }
    </script>
  </head>
  <body ondragenter="cancelEvent()" ondragover="cancelEvent()" type=text ondrop="drop();">
    Hi There
  </body>
</html>

In Windows Forms programming the event returns a variable of type DataObject. The DataObject has (Among other things.) a Files collection property


-- VB Code--
Private Sub OnDragDrop(Data as DataObject, _
                       Effect as Long, _
                       Button as integer, _
                       X as single, _
                       Y as single

  If Data.Files.Count = 1 then
    sDroppedFileName = Data.Files(1)
  end if

End Sub

Perhaps there is a similar structure in Java?

My guess is that it is in this dataTransfer object referenced on this page:

But I haven't had a chance to try it.

Yeah... I'm going to stay out of this conversation and just try to follow along as best I can. How do you guys think in script? I think my brain was completely maxed out after I added about 50% of AS3 to it, so HTML CSS PHP and AS3. I just don't seem to be retaining ruby like I did the others. Maybe I'm just getting old.

Not to worry Eric. The old adage "If you don't use it you lose it." applies big time to coding. I write VB Code for a living so I have to keep up on some things.

It is not a mystery to me that Ruby is hard to remember. I put it down to the strict case sensitivity and the lack of a comprehensive Integrated development environment.

what about a DWG/DXF export plugin for SU free ???

There is a separate dwg/dxf exporter available for v7 Free - search here for links.
It's not available for v8 but you can have v7 and v8 Free on your PC at the same time.
There is a dwf exporter under development for v8 Free here too - advance-search for 'honoluludesktop' the author...

@Gruff: There's no reason why you can't use VBS for your IE side webdialog code. Using Javascript is NOT a requirement for Sketchup Ruby. It doesn't care what what scripting language is running in the browser.

Nope

@gruff said:

Does Sketchup have command line parameters itself that can load a Ruby Script?

sketchup.exe -RubyStartup script.rb

You many need paths:
Try adding the sketchup program path to the %PATH% var,
then change working dir to the plugins folder where the script is located.

Not as they 'load' up but as an instance of them is started 'yes' - if you mean like MyTool.new(1,2,3) it's 'yes' just set the initialize method in the class to def initialize(arg0=0,arg1=,arg2=0) etc the =0 sets a default value for the arguments if they are not given.
Obviously methods take accept arguments a lot of the API does that... point.offset(vector, distance) where the Point3d method accepts one or two arguments...
If you want some code to run at startup of Sketchup then place it in a .rb script in Plugins that is auto-loaded and it will run - e.g. startupwithrubyconsole.rb containing the line require 'sketchup.rb';Sketchup.send_action("showRubyPanel:") will open the Ruby Console whenever Sketchup starts - pretty useless but just an example... or Sketchup.send_action("selectSelectionTool:") to change the default initial tool from the draw-line-tool to the select-tool...
