I did some digging on this, and I couldn't find a way to make this work
with a literal in the route itself.
Splatting works, though:
get 'baz/*ark_tag/:id/bar' => 'welcome#index', constraints: { ark_tag:
'ark:' }, as: :ark
will only match paths like "/baz/ark:/123/bar".
It's a little fussy with URL helpers, as you need to always specify ark_tag
or you'll get an error:
ark_path(ark_tag: 'ark:', id: 1234)
You'll probably want to define your own helpers that hide that.
The other, bigger issue is the OTHER features of the ARK spec that are
going to confuse & annoy the default URL parser. In particular:
* the dot-separated components of VariantPath elements. The default Rails
behavior appends a `.:format` optional parameter to the route. This
*doesn't* allow further dots.
* the `?` and `??` suffixes. The single question-mark, in particular, is
only detectable if you check the original request URI in the Rack request.
I'm also unsure how to talk the regular path helpers into producing a
single-question-mark URL.
If you're building an application which relies on complex routing of ARK
URLs, you may want to consider writing your own Rack middleware to hijack
the URL parsing process and transmute them into something more palatable to
the existing router.
