Subject: Re: rjust alignment

On Behalf Of Ross:
# I think I'm going crazy.  I tried to write a fairly simple program to

relax.

# toc.pages[x].rjust(lineWidth + offset + (10 - toc.pages[x].length))

toc.pages[x].rjust(offset+10)  #<-try this first

suggest to take a second look to #just... it rjusts the whole string. subtraction not needed :)

sample output should then be,

C:\family\ruby>cat -n test.rb
     1  class TableOfContents
     2  attr_accessor :chapters, :topics, :pages
     3  end
     4
     5  toc = TableOfContents.new
     6  toc.chapters = ["Chapter 1", "Chapter 2", "Chapter 3"]
     7  toc.topics = ["Numbers", "Letters", "Variables"]
     8  toc.pages = ["Page 1", "Page 57", "Page 117"]
     9
    10  lineWidth = 20
    11  3.times do |x|
    12          offset = toc.chapters[x] + ": " + toc.topics[x]
    13          offset = 40 - offset.length
    14          puts toc.chapters[x] + ": " + toc.topics[x] +
    15          toc.pages[x].rjust(offset)
    16     #toc.pages[x].rjust(offset+10,"x")
    17  end

C:\family\ruby>ruby test.rb
Chapter 1: Numbers                          Page 1
Chapter 2: Letters                         Page 57
Chapter 3: Variables                      Page 117

C:\family\ruby>


btw, i'd suggest you put "Chapter", and "Page" as headers, like so,

Chapter                    Page
 1: Numbers                   1
 2: Letters                  57
 3: Variables               117
