Asp Forum - How to escape spaces

Jonathan Wallace

10/1/2006 1:28:00 AM

I'm using ruby 1.8.4. I'm trying to use the gsub function to escape
spaces in a linux path that is stored in a variable.

When I attempt the following, t = "a B"; t.gsub(/ /, "\\ "), I receive
the following output:

irb(main):001:0> t = "a B"; t.gsub(/ /, "\\ ")
=> "a\\ B"

I'd like to get "a\ B" (without quotes, of course). Can someone point
me in the proper direction? Note: I've tried many different variations
with no luck.
Thanks,
Jonathan

Your trouble isn't with your gsub patterns I don't believe but with
what you are seeing in irb.

irb(main):107:0> t="a B"
=> "a B"
irb(main):108:0> t.gsub(/ /,"\\")
=> "a\\B"
irb(main):109:0> puts t.gsub(/ /,"\\")
a\B
=> nil
irb(main):110:0> 92.chr
=> "\\"
irb(main):111:0> puts 92.chr
=> nil
irb(main):112:0> Regexp::escape(t)
=> "a\\ B"
irb(main):113:0> puts Regexp::escape(t)
a\ B
=> nil

The representation of a backslash (\) is an escaped backslash (\\);
when the later is evaluated by the interpreter (i.e., you ask for its
value) you get the former. You can check the length of the string, or
just print it out, to see this:

s='a\b' # => "a\\b"
s.length # => 3
puts s # => a\b

I think Steve has killfiled you, so you probably won't get a reply.
Just wanted to let you know. Although it doesn't matter because hardly
anyone ever replies to you other than to put you in your place, but
you still comment on everything and anything.

Like I said: it doesn't matter whether or not Steve can even see or
would want to reply to you, so yes, pointing that out was indeed
pointless. But then replying to any of your posts is pointless, other
than to see the little doggy go for the stick once again.
Like you just did.

Actually, *all* your post are pointless.
You always say things you've said thousands of times before. Forever.
