[development] Human readable taxonomy URLs

[Bèr Kessels]

Hi,

Nice this comes up again, eventhough this has been discussed several times 
before w/o any result ;)

First of all: This goes far beyond only taxonomy. 
Second: this is only one possible use case.
Please look beyond blogs, in all these concepts. Drupal Is NOT about blogging, 
Blogging is merely /one/ possible case. 

Pathato does all this, but pathauto is not optimal ATM. The netto result is 
nice, but its inner workings are IMO not core-ish enough. 

That said, I proposed a concept of "mappings" a few times. I know that at that 
time Karoly liked the concept. 

<code>
hook_mapping() {
  $mappings[] = array(
    '#map' => '%screwdriver/details/%foo',
    '#variables' => array(
      '%foo' => 'bar',
      '%screwdriver' => toolbox(),
    )
  )
}
<code>

then l() and url() should run trough the mapping tos generate the urls. 

But wait! There is more. It can handle incoming links too! With a little 
fantasy, this can be used inside hook_menu, or even instead of hook_menu to 
map urls to code!
How wonderfull would it be to have a *central* place where all the url->code 
and code->url is generated in a consistent way! How fabulous would it nbe not 
to need a gazillion (I counted 160'000'000, yes 160 million) rows in one of 
my alias tables....) database entries, but to map the stuff dynamically.

  $mappings[] = array(
    '#title' => t('screwdriver details for %foo'),
    '#callback' => 'screwdriver_display_details',
    '#map' => '%screwdriver/details/%foo',
    '#variables' => array(
      '%foo' => 'bar',
      '%screwdriver' => toolbox(),
    )
  )


Yes. This is a performance issue. But no, that is not a reason to abandon it 
immediately. In fact, its a good reason to investigate it in more detail and 
see what this mapping can do for us.

PS: for more in depth details about this one should actually read the Ruby on 
Rails Mapping handbook. I have only paper books on this topic here, but there 
is a short and rough guide online:

You didnt think I came up with this myself, huh? ;)
