Rails - Aug 2011 - Invoking browser from Ruby script with URL argument: How?

Hi,

I''ve got the folowing script:
require "fileutils"

path = "K:/_Utilities/Apache/xampp/"
FileUtils::cd path
names = Dir.glob("**/index.html")
(0..4).each { |i|
      name = names[i]
      address = "file://" + path + name
      puts address
      exec address
}

It runs fine without line 10, "exec address", and produces:
file://K:/_Utilities/Apache/xampp/apache/htdocs/index.html
file://K:/_Utilities/Apache/xampp/htdocs/index.html
file://K:/_Utilities/Apache/xampp/htdocs/restricted/index.html
file://K:/_Utilities/Apache/xampp/licenses/gd/index.html
file://K:/_Utilities/Apache/xampp/php/docs/Structures_Graph/docs/html/index.html

But with line 10 active, I hang with:
K:\>ruby K:\_Projects\Ruby\_Ruby_Tests\TestDirTraversal
\TestDirTraversal.rb
file://K:/_Utilities/Apache/xampp/apache/htdocs/index.html
K:/_Projects/Ruby/_Ruby_Tests/TestDirTraversal/TestDirTraversal.rb:
10:in `exec'': Invalid argument -
file://K:/_Utilities/Apache/xampp/apache/htdocs/in
dex.html (Errno::EINVAL)
        from K:/_Projects/Ruby/_Ruby_Tests/TestDirTraversal/
TestDirTraversal.rb:10:in `block in <main>''
[snip]

Of course, if I pasted these addresses on successive lines of Word
(with space characters appended to each), I''d have a series of
hyperlinks that could control-click to invoke the respective URLs in
Firefox.

Is there a way I can repair the code here to achieve the equivalent
effect with Ruby?

Thanks in advance for any education you may offer,
Richard

Hi 7-stud,

Long time no "see".  Thanks for looking into my question.

Yeah, I know, but my question is how to repair my code so that it
works.  Or more specifically,  what command can I take which accepts
the text of a URL as an argument and invokes my browser with that
command as an argument?

Do you have a further idea?  I greatly appreciate learning any other
idea you might have on the question.

Best wishes,
Richard

Colin,
> exec "firefox #{address}"
You''re my hero!! I couldn''t think of what command I could use
to
invoke the browser on my machine.  I wish I had possessed enough
imagination to at least try that idea before posting my question.  I
did harbor the fancy of poking through Rails source code, thinking I
might find a clue there.  But that seemed daunting to me.

Best wishes,
Richard

I don''t think this would work on a max, since GUI apps aren''t
normally
in $PATH. You might be interested in the launchy gem.

Hi Fred,

I''m happy our paths crossed again.

The launchy gem looks cool.  The page I found it on also advertised
Process Explorer from SysInternals that replaces Window''s
StartMenu ... something I''ve wanted for a long time.  So, it''s
a
double-hitter.

Thanks and best wishes,
Richard

On a Mac, you don''t need launchy, just do:

open http://example.com/whatever

You don''t need launchy on any platform but it takes away from you the
hassle of deciding which strategy to use for a given environment.

Hi again,

Thanks for that link in your second post.  I only received it about an
hour after your original response, which only pointed out that I
lacked a function reference.  Hence my request for further idea(s).

Now I have a wealth of good solutions: Yours, Colin''s and
Fred''s

Thanks to you and them,
Richard
