Ruby » Ruby 1.8

# 

# Problem: with Ruby 1.8.8, Builder replaces all text with asterisks.  Demo:

#

require 'rubygems'

require 'builder'

x = Builder::XmlMarkup.new

x.a 'a'

puts x.target!

# 

# Root cause is a validity check in Fixnum::xchr, defined in builder/xchar.rb.

# This code has been extracted and simplified into a small test case.

#

n = 97

VALID = [ 97 ]

# Works in 1.8.7, 1.8.8, 1.9.1, and 1.9.2

case n when *[ 97 ]

  puts 'valid'

else

  puts 'INVALID'

end

# Works in 1.8.7, 1.9.1, and 1.9.2; FAILS in 1.8.8

case n when *VALID

  puts 'valid'

else

  puts 'INVALID'

end
