? [Question] - A Ruby Calculator ?

[Jim]

A minor thing - require 'Sketchup' causes sketchup.rb to load a second time. Loading sketchup.rb again doesn't really break anything, but it does create a duplicate Ruby Console entry in the Window menu.

It should be - require 'sketchup' (small s)

[Gruff]

Thanks for the advice Jim.

I updated the Ruby_Calc Zip attachment with your change. For any who get this far there are two calculators in this thread.
1) TG_Calc.exe which is a Compiled Windows program. It has a number of features.
2) Ruby_Calc.rb which is just a simple calc with no features.

Both only work with Windows and require the win32ole.so file.
both work by pumping keystrokes into the SU environment.

I thought this worked. I tried the zip file contents in both SU2013 and SU2014.
I also tried installing via the SketchUcation Plugin Store.

The script hasn't got require 'langhandler'
Add that after the require 'sketchup'
If an earlier loading script has already required it it might mask the lack of it.
However the line:
UI.menu("Tools").add_item($exStrings.GetString("Ruby Calc")) { rubycalc }
will also fail if $exStrings is undefined as it loads - as that might get setup by another script too.
Frankly I'd forget about the langhandler completely, and change it to read:
UI.menu("Tools").add_item("Ruby Calc"){rubycalc}

[JClements]

Thanks TIG. Works now per your post.

If I wanted to add info to the taskbar below such as:
"[+] = Add, [-] = Subtract, [*] = Multiply, [/] = Divide, [%] return remainder, [**] = exponent, [ ( ) ] = group functions"
what would be the proper ruby format and where should it be inserted?

# Ruby Calc is a simple SketchUp for Windows calculator.
# Feel free to hack and wack it.

# Since it is run as a loose procedure rather than a class
# it does not kick SU out of the currently running tool

# Bind the Menu Item 'Ruby Calc' to a short cut key
# For ease of use. (I use Alt-Q)

require 'sketchup'
require 'langhandler'
require 'win32ole'

def rubycalc
prompt = [""]
default = [" "]
input = UI.inputbox prompt, default, "Ruby Calc"
fanswer = eval input[0]
sanswer = fanswer.to_s + "{ENTER}{ENTER}"

# Create an instance of the Wscript Shell
wsh = WIN32OLE.new('Wscript.Shell')

#Try to activate the Sketchup window:
if wsh.AppActivate(' - SketchUp Pro') || wsh.AppActivate(' - SketchUp')
wsh.SendKeys(sanswer)
else
puts "Impossible"
end
end

if( not file_loaded?("ruby_calc.rb") )
add_separator_to_menu("Tools")
UI.menu("Tools").add_item("Ruby Calc") { rubycalc }
end

file_loaded("ruby_calc.rb")

v 2.0.0 cleanup by Dan Rathbun : 16 Aug 2014

1. Module wrapped in Gruff::RubyCalc
   
   
2. Method renamed: Gruff::RubyCalc::command()
   • statusbar help text displayed during input
   • evaluation rescue wrapped with retry
   • exits for empty input and cancellation
3. Tweekable text placed in module constants

Gruff has not logged in to SCF for a year and 4 months. Is he OK ?

[JClements]

Thank you for your help, Dan and TIG.

Hi! Does it work in SU2016 ? I have a message, " Could not activate SketchUp application window."

Hi! Does it work in SU2016 ? I have a message, " Could not activate SketchUp application window."

I just tested version 2 of "ruby_calc_2.rb" in SketchUp 2016, and this works.

Version 2 is in this post:

What is "it" you refer to ?
