convert ASCII to byte an vice versa

[chen li]

Hi all,

I have a small script as follows. I wonder how I can
change 65 66 67 back to ABC.

Thanks,

Li


C:\Documents and Settings\chen73>irb
irb(main):001:0> str="ABC"
=> "ABC"
irb(main):002:0> str.each_byte{|b|puts b}
65
66
67
=> "ABC"
irb(main):003:0>

# [65,66,67].collect{|b| b.chr}.join
=> "ABC"
# [65,66,67].pack("C*")
=> "ABC"

In addition to manually using Integer.chr, you may find Array.pack
useful:

esau:~$ irb
irb(main):001:0> 'asdf'.unpack('c*')
=> [97, 115, 100, 102]
irb(main):002:0> [97, 115, 100, 102].pack('c*')
=> "asdf"
