creating directory "http://example.com"

[Comfort Eagle]

How do I create a directory 'http://example.com' without it getting
broken up because of the '/'s ?


url = 'http://example1.com'
Dir.mkdir(url)

 

[Comfort Eagle]

Very simply, you can't. That is an URL, not a directory path.

Insteda of asking this hypothetical question about a hypothetical
solution,
please state the problem to be solved and someone will help you.

Hmm, ok then. How could I strip http:// from that string?

url = 'http://example.com'
url.gsub!( /^http:\/\//i, '')

Interesting. Newb Q, I'm sure, but when I put that in a while loop I
get: "private method `gsub!' called for ..." /me googles & still
scratches head.

"
res.each do |url|
puts url.gsub!( /^http:\/\//i, '')
end
"

 

[Comfort Eagle]

Does this work for you?

"http://www.test.com".each do |url|
puts url.gsub!( /^http:\/\//i, '')
end

Yes. Re-evaluating my assumptions....

What is "res"? Is it an array of strings?

I thought it was:
res = dbh.query("Select url FROM sites")

 

[Comfort Eagle]

Better:
I thought it was array of strings & looks like it to me??

res = dbh.query("Select url FROM sites")
while url = res.fetch_row do
puts url.gsub!( /^http:\/\//i, '')
end

It sounds like you've got something other than strings -- or at least
one thing that isn't a string -- in your array. gsub(!) is sort of
weird because, even though it's only for strings, every object has the
method. That's because it's a "top-level" method... and *that's*
because it defaults to operating on $_, the default variable.

Anyway, mainly you just need to figure out what non-string is being
assigned to your url variable.

Well, it's easy enough to find out.

Before you apply "gsub!", test the class:


puts url.class # Add this. Read the result. Then decide what to do.

Brilliant. Here's the output:
Array
Array
Array

Definitely not strings.

All right. Now change "puts url.class" to "p url" to figure out what you
should do with those Arrays.

url = row[0] fixed that right up.

Thanks everyone.
