This is a worth while hook to add to the core code. It will ease the
implementation of more multi-lingual sites in drupal and provide better
support for a broader community of users/developers.

I need a URL rewrite hook sometimes, here is an implementation, with
ample comments. I looked into arg() to see whether it needs a reset
parameter, and it does not, but it contained a minor bug, which is also
fixed.

Performance boost.

This is really needed by i18n module, and maybe other modules could use
it to add some extra information in the query string.

this seems just an evil plot to cater for the evil hack that i18n.module
is. --

killes, while I know you do not like the current implementation of i18n,
that module exists and even works. If you do not like the current
approach, you can always write a better one. And also, please note we
try to introduce non-i18n specific solutions this time.

"it works" has never been a consideration in Drupal development, don't
let us start to use it. I don't need an i18n module. Had I had the urge
to write one, it would have been based on walkah's excellent start to be
seen here:
http://cvs.drupal.org/viewcvs/drupal/contributions/sandbox/walkah/translate_node/
I don't see anything non-i18n specific here. let us not pollute low
level functions such as url() with custom hacks.
------------------------------------------------------------------------

Why extend url() and why not the alias retrieval functions? BTW at that
time it was decided that a single function should be used
(conf_url_rewrite()) and not a hook, because of performance reasons. If
you provide the functionality this was, then conf_url_rewrite() gets
confusing, and even meaningless if you do it in the alias retrieval
functions themselfs.

Goba is so right, that I was already working on it.

This second version is more limited, and wont be that useful, because in
case an alias exists, the rewritting is skipped.
IMHO, the aim for this patch should be allowing modules to add
information in the path or in the query string, for *all* the outgoing
urls. I was thinking of i18n module and language information, but this
can be useful for other modules too.
So please, let's stick to the previous version of the patch
------------------------------------------------------------------------
Thu, 18 Aug 2005 11:45:23 +0000 : Goba
Jose, so you advocate only mangling URLs on output? Really?
------------------------------------------------------------------------
Thu, 18 Aug 2005 15:41:41 +0000 : Jose A Reyero
Goba, yes, my idea was to provide a hook, so any module can mangle the
path/query string. What will happen with that incoming paths is a
different story, I mean any module can access the query string any time
later... And I'd like this to be separated from path aliasing, which can
be done in a different step...
Ideally, of course, this would be done for outgoing and incoming urls,
but there's a number of issues, like incoming path processing being
done before module loading, in common.inc... Another issue, IMHO, is
that current url handling is a bit messy and could be better
streamlined.
But the first patch was simple enough and quite straight forward, at
least it works for *all* outgoing URLs, and allows to rewrite query
strings, while the second one, I see much more limited use for it....
------------------------------------------------------------------------
Thu, 18 Aug 2005 17:07:13 +0000 : Goba
Jose, AFAIS if you mangle with the outgoing URLs (eg. put 'en/' before
all URLs), and there will be nothing in the incoming processing to
strip that, this will directly lead to 'page not found' replies. But I
probably fail to see the exact use case you would like to propose this
for.
------------------------------------------------------------------------
Thu, 18 Aug 2005 17:48:13 +0000 : Jose A Reyero
Goba, yes, basically you are right... But these are my use cases:
For i18n
----------
- Add language prefix at the beginning of the outgoing urls
- Remove it in the module init hook.
Yes, I know... this is probably some of what killes calls evil hacks
:-(
But with this new hook, I could also think of adding language in the
query string. And maybe some other modules could want to add some info
in the query string. There are a number of reasons for language to be
in the URL -search engines, links...- and also the ability to create
path aliases with or without language...
Hackish? Yes. But right now we are facing the following dilemma: no
specific calls for non core modules -which I dont disagree with- but
then any implementation of this, for not to require patching, will have
to be in a module, and then incoming paths are first processed before
module loading, and on top of that we have the cache system.... so its
quite a complex thing....
I'd be happy with any idea to implement this more cleanly, or maybe we
should aim higher, like reworking the whole init thing and path
pre-processing... What we are trying for the moment is to introduce
only some general use hooks, like this small patch... otherwise it is a
too big all-or-nothing question to get this working in Drupal....
Thanks for your comments and I'd appreciate any suggestion.

Updated simplified patch.
As other patches are already in, we only need this to run i18n module
with Drupal 4.7 without patching!!
------------------------------------------------------------------------

I would be more useful to have a similar hook in drupal_get_path_alias()
and drupal_get_internal_path().
------------------------------------------------------------------------

patch applies (with offset) and doesn't break anything, as i could see.
a lot of people are interested in i18n, so please include this last
one.
further the possibilty inject a query-string might be useful in other
cases.
