Escape character is strings

[Deepu Damodaran]

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

Your irb line 5 is just fine. It's the line 4 that seems wrong. To
redo your line 4...

irb> fold = "abcdefgh/ajf;ldsj\\def"

or...

irb> 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)
