Hi All,

I'm trying to get the Ruby Tidy gem installed but I am having problems.
I downloaded and installed HTML Tidy from source first, then installed
Ruby Tidy from the gem:

gem install tidy

And it reports that it went ok:

Bulk updating Gem source index for: http://gems.rub...
irbSuccessfully installed tidy-1.1.2
Installing ri documentation for tidy-1.1.2...
Installing RDoc documentation for tidy-1.1.2...

But when I issue 'require 'tidy'' (in my rails 'script/console') it
reports false, as if it isn't installed.

Any ideas? I'm on OS X 10.4.8 on my workstation and FC5 on my server.

Are you sure you require 'rubygems' before requiring 'tidy'?

It was required already then. If you are requireing something for the
first time in that interpreter, it returns true, if you are doing it
for the second+ time, it returns false, if it wasn't installed, it
would result in a load error

Don't you have to have libtidy installed in addition to the gem?

Some systems have it already installed. For example, on my OS X it's
here:

/usr/lib/libtidy.dylib

Yes, but that would have caused a failure at the 'Building native
extensions' phase of the gem install?

The false result the OP is seeing means that either tidy was already
required, or an (old?) gems bug has reared it's head. Generally, I find it
best to ignore the return value from Kernel#require, since it will throw a
LoadError if the library cannot be loaded. In this case, I suspect the
library is loading just fine, despite the 'false' return from require.

Try loading rubygems first:

require 'rubygems'
require 'tidy' # or: require_gem 'tidy'

As someone pointed out earlier, that would throw a LoadError - and
anyway, Rails has dependency on rubygems so this should not be the
problem...

require_gem 'tidy' is not supposed to do anything. If I got the threads
in which that occured right, require_gem only specifies the preferred
version of a gem, you still have to require files from inside them.

I've had similar problems before, but require doesn't return false on an
error. It returns false if the file has been included before and there
is not loaded again. When an error occurs, require will throw an Error.
Try and use some of the methods from Tidy and see if they work.

Kind regards,

Wim
