Methods from Support files

[ktkoh]

I am trying to move some def's that are common to most of my joint scripts to a support file. I am already using Arithmetic parsing.rb which I think Jim sent me to convert equations into calculated lengths. I thought I could add other def's there and use them from the main program. I get this error message
Error: #<NoMethodError: undefined method cal_xCL_points' for ArithmeString:Module> C:\Users\Keith\Documents\ShopProjects\TestPlugins\K2WS_Tools\KK_Tools_Template.rb:214:in onLButtonDown'

The code in the support file is:

  def ArithmeString.cal_xCL_points(x1,e_len,dir_x,spacing,qty)
    @xcl=Array.new qty.to_i
    case spacing
      when "Symetrical"
        #Debug UI.messagebox("Spacing = " + spacing.to_s)
        if qty == 1
          @xcl[0]=x1+(end2CL*dir_x)
          #Debug UI.messagebox("@xcl[0] = " + @xcl[0].to_s)
          #Debug UI.messagebox("Completed qty = " + qty.to_s)
        elsif qty == 2
          @xcl[0]=x1+(end2CL*dir_x)
          @xcl[1]=x1+((e_len-end2CL)*dir_x)
          #Debug UI.messagebox("Completed qty = " + qty.to_s)        
        elsif qty == 3
          @xcl[0]=x1+(end2CL*dir_x)
          @xcl[1]=x1+((e_len/2)*dir_x)
          @xcl[2]=x1+((e_len-end2CL)*dir_x)
          #Debug UI.messagebox("Completed qty = " + qty.to_s)
        elsif qty >= 4
          #Debug UI.messagebox("Started qty = " + qty.to_s)
          @xcl[0]=x1+(end2CL*dir_x)
          @xcl[qty-1]=x1+((e_len-end2CL)*dir_x)
          @xcl[qty/2]=x1+((e_len/2)*dir_x)
          n =(qty-2)/2  #loop number
          sn = 1 #Starting number
          i = 0
          while n > 0
            temp_offset=cl_offset[i]
            #Debug  UI.messagebox("CL Offset = "+ temp_offset.to_s)
            @xcl[sn]=@xcl[sn-1]+((temp_offset)*dir_x)
            @xcl[qty-1-sn]=@xcl[qty-sn]-((temp_offset)*dir_x)
            sn = sn + 1
            n = n -1
            i = i + 1
          end # while n > 0                
        end #if qty == 
        #Debug  @xcl.each {|e| UI.messagebox("Symetrical CL point = "+ e.to_s)}           
      when "Equal"
        #Debug UI.messagebox("Case Spacing = " + spacing.to_s)
        equal_offset=(e_len-(end2CL*2))/(qty-1)
        @xcl[0]=x1+(end2CL*dir_x)
        @xcl[qty-1]=x1+((e_len-end2CL)*dir_x)
        n =(qty-2)  #loop number
        sn = 1 #Starting number
        while n > 0
          @xcl[sn]=@xcl[sn-1]+((equal_offset)*dir_x)
          sn = sn + 1
          n = n -1
        end # while n > 0
        #Debug @xcl.each {|e| UI.messagebox("Equal CL point = "+ e.to_s)}        
      when "User"
        #Debug UI.messagebox("Case Spacing = " + spacing.to_s)
        @xcl[0]=x1+(end2CL*dir_x)
        n =(qty-1)  #loop number
        sn = 1 #Starting number
        i = 0
        while n > 0
          user_offset=cl_offset[i]
          #user_offset=user_offset.to_l
          #Debug UI.messagebox("user_offset = "+ user_offset.to_s)
          @xcl[sn]=@xcl[sn-1]+((user_offset)*dir_x)
          sn = sn + 1
          i = i + 1
          n = n -1
        end # while n > 0
        #Debug @xcl.each {|e| UI.messagebox("User CL point = "+ e.to_s)} 
      when "Fixed"
        #Debug UI.messagebox("Case Spacing = " + spacing.to_s)
        @xcl[0]=x1+(end2CL*dir_x)
        n =(qty-1)  #loop number
        sn = 1 #Starting number
        while n > 0
          fixed_offset=cl_offset[0]
          @xcl[sn]=@xcl[sn-1]+((fixed_offset)*dir_x)
          sn = sn + 1
          n = n -1
        end # while n > 0
        #Debug @xcl.each {|e| UI.messagebox("Fixed CL point = "+ e.to_s)}         
    end #case spacing
    #Debug UI.messagebox("End Spacing = " + spacing.to_s)
  end #cal_xCL_points

the code in the main file is:

UI.messagebox"Calculations and then Add Features for first part"
          x1=0; e_len=6.0; dir_x=1;spacing="Symetrical"; qty=3
          ArithmeString.cal_xCL_points(x1,e_len,dir_x,spacing,qty)
          UI.messagebox("Center line points = " + @xcl[1].to_s)

I know the file is read because in earlier statements I used:

todist_input=ArithmeString.string_to_length(results[1].to_s)
    if !todist_input then todist_input=results[1] end
    @@todist=todist_input; ans[1] = @@todist

and this works properly

As always I appreciate the help. [I do use the SketchUp Book, examples and api code and try lots of things before asking].

Where is this 'support-file'... is it auto-loaded or do you 'require' it or 'load' it from a subfolder?
To test if it's loading add a line in the start of the
def ArithmeString.cal_xCL_points(x1, e_len, dir_x, spacing, qty)as puts "ArithmeString.cal_xCL_points is here!"
Then in the Ruby Console type
ArithmeString.cal_xCL_points(1, 1, 1, 1, 1)
I know what's passed to it will likely break it... but at least we'll get to the "ArithmeString.cal_xCL_points is here!" in the Ruby Console, IF it's been loaded and it runs...

Thanks TIG that got me going. I found that my program was using the Arithmetic methods from an already loaded file.
However as I got into i farther I found that I was going to have to rewrite to pass several more variables and I am going to leave that for another time. I revised the names and added KK_ to the front so I would know where the methods were that I was using.

Thanks

Your trying to add a module function to an existing module.

Your method def needs to be wrapped within a:
module ArithmeString #---- paste method def here end
block, otherwise the instance var @xcl will be inaccessible.

THIS thread needs to be moved to the Developer's forum.

Moved.
