Description

def tokengenerator
random = Random.new
alpha = Array.new
('a' .. 'z').each do | c |
alpha << c
end
('A' .. 'Z').each do | c |
alpha << c
end
numbers = %w{ 0 1 2 3 4 5 6 7 8 9 }
loop begin
unique
string = ''
0.upto( 19 ) do | n |
if n.even? then
uniquestring << alpha[ random.rand( 52 ) ]
else
unique
string << numbers[ random.rand( 10 ) ]
end
end
break unless @sessions.include?( uniquestring.tosym )
end
unique_string
end

causes:

/usr/local/lib/ruby/1.9.1/rubygems/custom_require.rb:55:in require': /home/devel/ISF_Server/Actors/DataProvider.rb:49: syntax error, unexpected keyword_do_block, expecting keyword_end (SyntaxError)
0.upto( 19 ) do | n |

from ./server-work.rb:7:in `'

but replacing begin/end with { } works.

Hi there,

Try 'loop do' instead of 'loop begin'

Best,
Nathan

My bad, thanks, Nathan. Switching between languages too often! :D
