help using facets?

a non y mouse

2/8/2006 10:37:00 PM

i just discovered facets and would like to begin using them, but am
having issues:

require 'facets' works, but i am unable to use anything suggested in the
rdoc or the little stuff i've found online.

based on
<http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-talk/..., i
should be able to do

Time.use Facets, :stamp

or

Array.use Facets, :each_permutation

but both give errors:

tinker% !.
/facets.rb
/facets.rb:5: uninitialized constant Facets (NameError)
from ./facets.rb:3
tinker% cat facets.rb
#!/usr/local/bin/ruby

require 'facets'

Time.use Facets, :stamp
tinker%

i do have the gems installed:

tinker% gem list | grep facets
facets (1.0.2)
facets_core (1.0.2)
facets_more (1.0.2)

same thing if i try the Array line. sooo..what gives? i'd really like to
be able to use its Crypt module.

thanks

Couldn't reproduce this with whatever ruby there is in the Ubuntu
repositories, latest rubygems, and whatever "gem in -y facets" gets me.

The Facets module does indeed seem to exist, however, my hopes shatter right
after that. Time doesn't have a #use class method, in fact, there is no such
method in the API documentation.

The deprecated method in the documentation doesn't help any either.

How -do- you use this library then?

The website is also in slight need of spellchecking, I wonder if this would be
proper to report via the project bug tracker.

Be sure RUBYOPT="-rubygems" then

require 'facet/time/stamp'

> i'd really like to be able to use its Crypt module.

require 'facet/crypt'

Gah. #stamp is an instance method? Ah well, I thought it was a class method
because it would look good in code that way. I should hint the Facets
developers towards that.

So the usage in the announcement from a few months ago didn't describe changs
that were released yet?

Is this what you want?

def Time.stamp(*args)
now.stamp(*args)
end

I will add to next version of Facets if so.

Yep, something like that. I have no idea how often people need textual
timestamps of the current date though, so it might not be a particularly
useful addition. It's just the first usage that came to mind when I saw
someone asking about that functionality.
