Hi, I've been having a little problem with this. most of my ruby is from
rails and both are shaky.
okay what I've got is a string (which is a browser user agent) and I
would like to search that string with a predefined array of browsers.
I've done this in php so I'm positve an easy solution exists in Ruby
this is what I got @string = "mozilla/5.0 (macintosh; u; ppc mac os x; en)
applewebkit/418.9.1 (khtml, like gecko) safari/419.3"

You could use:
@string.include?(b)
or, if you want to be more careful about false positives (like, if
"msie" was a substring in some other browser's string), you could do:
array.find {|b| @string[/#{b}/] }
which anchors to word boundaries. (All untested, so check for typos
and/or logic errors

Iterates over each entry of the array, makes a regexp of it (the
/#{b}/ bit) and matches that against the string. (Ideally, you want @string =~ Regexp.escape(b), but with the strings you have it comes to
the same thing.)

You'll probably have 10 (better) answers for this by the time I've
posted, but here's mine:
a = "something is here"
b = [ 'x', 'y', 'g', 'q', 'z' ]
b.find { |c| Regexp.new( c ).match( a ) } => "g"
The regexp.new creates a new regex (surprise) like /c/, and then
searches for it in the string a. If it's not found, match returns nil,
which is false, so find continues. If it's found, match is an object,
which is true, so find exits with that item from the array.
this is what I've been trying to do.
array.find {|b| b == @string}.to_s
this does't work I know, but I'm I in the right direction?
The find is on the right track, but what you're saying is that the
array item must match the full string ... which, based on your problem
description, is incorrect.

It focused on larger word sets that you're looking at, but it might give you a different perspective on the problem.

Reminds me of Knuth's great saying
Beware of this code, I have only proved it correct, I have never tried it!
You'll be allright

You could use:
@string.include?(b)
or, if you want to be more careful about false positives (like, if
"msie" was a substring in some other browser's string), you could do:
m, agent = *@string.match(/(shiira|msie|safari|firefox|netscape)/)
p agent
outputs
safari
If you need further clarification of this code, just let me know.

can I tag a regex on to this to pull the version of the browser? I
understand I might have to to break this down as some useragents are
differently setup.

Are you sure?
array.find{|s| @string[/\b#{s}\b/] }
Thanks. I had this weird feeling something was wrong when I sent that
message.... I think the 'b' variable name fooled me

To each his own I like the loop -- though I'm not sure why I used
instead of just matching. I think I somehow had map on the brain.
