Rails - Jul 2005 - Ruby/RoR equivalent of PHP's phpinfo() function ?

OK, I''ve been won over from the PHP world where I''ve been
happy for 6
+ years or so, and is now eager to create some new solutions with RoR.

In the PHP world, you can easily find out what abilities your PHP  
server has by running this little snippet in a page: <?php phpinfo(); ?>

Is there an equivalent in RoR ?

Secondly, almost all PHP installations comes with support for GD  
(graphics library) and other image related functionalities built-in.  
Can I expect most hosts like TextDrive, Dreamhosts etc. to have the  
Ruby equivalents (if there are any?) installed by default ?


Kind regards,

Mats

Regarding image libraries: I am using the RMagick interface to
ImageMagick (that most hosts already support) and it is good.

http://rmagick.rubyforge.org/

I am still in development mode, so I can''t give more details on how it
works on live servers.

Packages in ruby are installed with gems.  Type ''gem list'' on
your
host to see what they have.  Textdrive has a lot of gems, but no
rmagick.  I see no reason why they wouldn''t install it, however.

I can''t speak for any other hosts, but any reasonable host should be
able to accommodate you.  If not, find a new one...

There is a Ruby extension to the gd graphics library.

TextDrive does in fact have RMagick in some capacity for doing that,  
as my require ''RMagick'' (and subsequent use of the package)
works
like a charm. It''s really quite nice.

DreamHost does not, and most others don''t have those nice Ruby  
bindings - and who knows when they''ll all catch up with TextDrive.

Personally I have found that the phpinfo() function, although being a
nice feature has all too often become a forgotten security threat. I
cant'' begin to tell you how many people actually forget that they have
one of these pages sitting around on their publically viewable
domains. It''s one of the first things I check for in doing PHP
security, especially if I know they are using certain programs which
have default debugging pages with the phpinfo() function.

Gem does a fine job of listing everything you need from the command
line, which is a much more secure place to play from. And most hosting
companies would be happy to provide you with a list, rather than have
you place a phpinfo() function on their servers. ;)

I install a number of things via FreeBSD''s port system so a gem list  
wouldn''t show it.
