Array

Pattern
Pattern create
Assume the pattern length = 500 (you can change it to any value). By default this will create 20280 probabilities max.
pattern_create = ('Aa0'..'Zz9').to_a.join.each_char.first(500).join
In case you need longer a pattern (ex. 30000) you can do the following
pattern_create = ('Aa0'..'Zz9').to_a.join
pattern_create = pattern_create  * (30000 / 20280.to_f).ceil
Pattern offset
I'll assume the pattern was equal or less than “20280” and we are looking for “9Ak0” pattern characters. The pattern_create should be initialized from above
pattern_offset = pattern_create.enum_for(:scan , '9Ak0').map {Regexp.last_match.begin(0)}
Note: This does not consider the Little-endian format, for that there is extra code that should be written. For more info, please take a look at the following [code][1].
Generate all hexadecimal values from \x00 to \xff
puts (0..255).map {|b| ('\x%02X' % b)}
To change value presentation from (\xea to 0xea), change \x%x to 0x%x
To make all letters capital (\xea to \xEA) , change \x%x to \x%X
Generate all printable characters
(32..126).map {|c| c.chr}
short and unclean
(32..126).map &:chr
