Subject: Re: Alternatives to ?\C-n, ?\M-a etc in ruby 1.9

From: Nit Khair [mailto:sentinel.2001@gmx.com] 
# But what about ?\C-a or ?\M-a (control and meta keys). 
# Is there a workaround for them?
# Sorry, I don't have 1.9, so cant try out "\C-a".ord .

am on a win machine, so my ruby1.9 is old ver. sorry.
anyway, ctl and meta still work.

eg,

C:\family\ruby>\ruby1.9\bin\ruby -ve 'p "\C-m"; p "\r"'
ruby 1.9.0 (2008-06-20 revision 17482) [i386-mswin32]
"\r"
"\r"

C:\family\ruby>\ruby1.9\bin\ruby -ve 'p "\C-m".ord; p "\r".ord'
ruby 1.9.0 (2008-06-20 revision 17482) [i386-mswin32]

# Also, To be compatible with both 1.8 amd 1.9, would i 
# use something like: 
#   ch = str.respond_to? :ord ? str[0].ord : str[0]
# or
#   str[0] is_a? Fixnum ? str[0] : str[0].ord

why not create your own String#ord func?

i think string#ord works for both 1.8.7 and 1.9, so you just have to create one for 1.8.6
