Hi all,
I'm very new to Ruby. My problem is simply to search for '\' character
from a string. The string is the windows file path. I have to either
escape the '\' character or substitute it with '/'. But String::include?
methods doesn't seems to be helpful. Please see the log.
irb(main):004:0> fold = "abcdefgh/ajf;ldsj\dfd"
=> "abcdefgh/ajf;ldsjdfd"
irb(main):005:0> puts fold.include?("\\")
false
=> nil
irb(main):006:0> puts fold.include?("\")
irb(main):007:1"
so how can we search for the '\' using .include?
Thanks and Regards,
Deepu D

In a quoted expression, the backslash escapes the following character,
so you need to use two backslashes instead, like this:
irb(main):004:0> fold = "abcdefgh/ajf;ldsj\\dfd"
=> "abcdefgh/ajf;ldsj\\dfd"
irb(main):005:0> puts fold.include?("\\")
true
=> nil

Your irb line 5 is just fine. It's the line 4 that seems wrong. To
redo your line 4...
fold = "abcdefgh/ajf;ldsj\\def"
or...
fold = 'abcdefgh/ajf;ldsj\def'
The same goes for your line 6. Your are escaping the second " and
that's why it's asking you for another one.
hth,

You can use the integer equivalent of the character as well.
fold.include?(92)
