From absolute to relative IRI?

[kjetilk]

There is code to go from a relative IRI to an absolute IRI, but can we go the other way?

Say that we have e.g.

my $iri = IRI->new(value => "http://www.hestebedg\x{e5}rd.dk/hest/ku");

and then, from some other place, I get the base

my $base = IRI->new(value => "http://www.hestebedg\x{e5}rd.dk/hest");

Can I somehow get the relative URI (or just the string) /ku?

If not, then, that's on my wishlist :-)

That's on my wishlist, too. I started work on this in the rel branch, but I recall it having some complicated corner-cases that I wasn't able to address in the time I spent on it.

[kjetilk]

Oh, OK, I wasn't aware. I can't see any branches though, could you please push it here?

[kasei]

Oops!

[kasei]

Just a warning, I'm not sure where I left the code in the rel branch. There's some code, and tests, but no guarantees that the tests cover all cases, or that the code is the right approach! :)

[kjetilk]

OK, interesting!

So, was the corner case of such a nature that it could break things, or just a suboptimal case?

[kasei]

I don't remember. I can look into the code tomorrow and try to figure out where I left things, but I can't do it tonight.

[kasei]

My main concern was avoiding a situation where I released code that did the wrong thing for the corner cases, without being able to identify them and at least fall back on bailing out and just using absolute IRIs.

[kjetilk]

Oh, great! Don't worry, it wasn't an immediate need, it just struck me as something that would have been a great enabler in many designs.

[kasei]

Agreed. I'd love to get this sorted out. I just have so many things fighting for my time at the moment!
