Custom Dynamic Component Functions = Ruby links

[TIG]

That's fine if you're happiest with this approach...

if you ruby geniuses could figure out a way to either A) add faces to nested edges or b) find a way to control individual faces/edges within a component via DC then these things could be awesome.. otherwise, DCs appear to be limited to cubes for any practical construction application (and that's a huge limit imo because the cube type stuff is super easy to draw anyway)..

I wholeheartedly echo that request.. this would overcome a variety of issues for my work. I design for events, and have made all my own lighting fixtures / speakers / projectors etc, which are all DC's that I can adjust the attributes of (some of my library is published here: http://sketchup.google.com/3dwarehouse/cldetails?mid=e94a8eafed72d755701d728505a21ed0&prevstart=12). But I come across that stumbling block frequently, with wanting to do something as simple as move one face of a cube (not in alignment with the cube, but side-to-side.. like a parrallelogram)..

Custom functions are a helpful half-way point but if everyone needs the same ruby script installed to be able to utilise it, they don't serve all that well. Is there any way to address individual edges/faces of a component using ruby in a DC spreadsheet formula? If I can do that, and modify them using existing functions, then I'd be more than satisfied.

Thanks !

--use component options to determine dimensions
--in outliner, click on 'CUTTERS'
--select 'Outer Shell' via solid tools
--select 'Subtract' via solid tools
--click on the orange board (stringer_uncut)
--explode
--the stringer will be a single solid component named 'Stringer'

Once the DC is configured, these steps could be automated into a single step (via a menu or tool button.) I am making the assumption of consistent Component names being used i.e Components named "Cutters" are always subtacted from Components named "Stringer_Uncut"

hey Jim.

since the time of this thread, I have automated the finishing parts of the DC using AppleScript. I found a pretty decent way to create macros for sketchup.. the macros are osx 'services' which (can) reside in a specific app's menus (or they can be available system wide)

which reminds me. maybe I should type up a thread showing how to accomplish this.

Jeff.. please DO.

Then if we can find a PC complement (likely OLE,) these "services" could be wrapped as Ruby objects or classes. A platform conditional if block would define the Ruby interface, using AppleScript on the Mac, and OLE on PC. In this way we could have a cross-platform Ruby interface for plugins.

hmm. I'm not too sure it would work with what you're suggesting. (at least the way I've been going about it)

I'm doing GUI scripting so it's basically just keystrokes and menu items.. you can accomplish quite a bit this way (I actually have one script that uses a little but of ruby in there via the console )

the thing that's good about it is it's not very complicated so a lot of people should be able to make their own macros this way (and a bonus is that you don't have to install any additional software)..

The Windows equivalent can be accomplished via Windows Scripting.

Here's a VBScript example:

Sub Wait
	Wscript.Sleep(1500)
End Sub

set WshShell = WScript.CreateObject("WScript.Shell")
'WshShell.AppActivate "- SketchUp"
Command = """C;\Program Files (x86)\Google\Google SketchUp 8\SketchUp.exe"""
'MsgBox Command
WshShell.Run(Command)
Wait
WshShell.SendKeys "%u" ' My SU Shortcut to open Ruby Console
Wait
WshShell.AppActivate "Ruby Console"
Wait
WshShell.SendKeys "require_all 'c;/plugins'{ENTER}"

> WshShell.SendKeys "require_all 'c;/plugins'"
> WScript.Sleep 1000
> WshShell.SendKeys "{ENTER}"
> 

is something like that easy to run from within sketchup? (that's sort of the beauty of osx services.. they become a menu item so activating the script is the same for anything else in sketchup.)

regardless, you guys could probably write a macro recorder in ruby that in turn produces these services :enlighten:

nothing to do with recording cursor movement etc.. AppleScript can't handle it.. (eg- edit component, select all, explode, generate faces, exit component)

those steps are what ruby watches, then places the commands in a .scpt format and moves them to the services folder.

Yep.. what Jim said.. however, his example can also be written in Ruby (on PC using the Win32ole.so extension, which many users have already installed to their "Plugins" directory, or they have it in their full Ruby library directory, if they have installed the full Ruby edition, and pushed it's lib path into the $LOAD_PATH array.)

So to use the "SendKeys" example (which seems to be a common function name in many of the programming languages available, from low-level C, to the higher level languages such as VB, C# etc.)

Goal: To provide a cross-platform Ruby method, named SendKeys() that sends keystrokes to the Sketchup application.

1) Choose a community namespace. As an example, lets say (for argument's sake,) this will go within the SKX project namespace, and beneath that we'll wrap it within a GUI submodule.

module SKX; end # make sure outer namespace is defined

module SKX;;GUI

  if RUBY_PLATFORM =~ /(darwin)/i # on Mac

    def self.SendKeys(keystring)
      # the Mac code using AppleScript
    end

  else # on Windows

    def self.SendKeys(keystring)
      # the WIN code using Windows Scripting Host
    end

  end

end # module SKX;;GUI

This is the one file approach, which may not be the best, because it makes everyone update their file(s) even when a revision is made for a certain platform. I show it to make an important point about Ruby, in that it is a dynamic language that can be defined during runtime. (In this example, we would define the same method, two different ways, depending upon which platform it will run on.)

The separate file approach may be better. Where a user chooses an install package for the proper platform, so that their "Plugins/SKX/GUI" directory, only contains the Ruby object definitions for their platform.

To use this proposed feature, scripters would simply require the proper module definition file:

require("SKX/GUI/keyboard.rb") SKX::GUI::SendKeys("require_all 'c:/plugins'"+SKX::GUI::KBD::ENTER)

P.S.: Locally within a custom module or class, a scripter can create 'nickname' shortcut references that point at long nested qualified objects, like:
gui = SKX::GUI @kbd = SKX::GUI::KBD
or even:
ENTER = SKX::GUI::KBD::ENTER
So don't be afraid of well organized, multi-nested module namespaces.
Also.. if say, the KBD submodule was just a mixin module of constants, scripters could, if they wished, mix it into their module(s) or class(es) by inclusion:

module Author;;FancyPlugin
  require("SKX/GUI/keyboard.rb")
  include(SKX;;GUI;;KBD)
  # now all constants in KBD module, are mixed in.
end

the wording in AppleScript is keystroke.

keystroke "v" (for the v key)
keystroke "V" (is for shift + v)
keystroke "V" using command down (for shift-cmmd-v or paste in place)

likewise, you can also do menu items:

click menu item "Outer Shell" of menu "Tools"

Yea.. and what is the point your making ??

just saying that ruby could write the macro script. (but I'm pretty sure I'm not thinking about doing this the right way )

like if a user turns on the macro recorder (.rb plugin) then does a series of commands they want to automate then click 'stop ecording'(or whatever).. ruby will then write the commands used in a scpt file in the format of my previous post.. then puts it in the services folder so the user now has a sketchup macro without leaving sketchup or manually typing up an AppleScript.

edit. oh, I was also just saying it's 'keystroke' in applescript as opposed to 'sendkeys'

Jeff,

Very much hope you do a thread on how to use services in Mac. I've moved back to Mac after a too long trip through various PCs and am very curious about Services, AppleScript, and Automator. Anything you put together for Services in SketchUp would be appreciated.

I'm going to do a thread today on it.
I think I'll keep it super basic at first then the thread can evolve from there into the other possibilities.
