I couldn't figure out how to do exactly this, as my Ruby-fu is very
very young. So I simply defined a new tag called now, as a clone of
date:
desc %{
Renders the current date. The format attribute
uses the same formating codes used by the Ruby @strftime@ function.
By
default it's set to @%A, %B %d, [EMAIL PROTECTED]
*Usage:*
<pre><code><r:now [format="format_string"] /></code></pre>
}
tag 'now' do |tag|
page = tag.locals.page
format = (tag.attr['format'] || '%A, %B %d, %Y')
if date = Time.now
date.strftime(format)
end
end
SInce I used both Copy and Paste, I presume this violates DRY all over
the place. I'm still learning, and this works for now, but I'd love to
see how you would create a :now symbol and pass it to r:date.
