Trying to generate URLs for linking into the Racket docs. I get the error
below, but only when the package/identifier combo in question are installed
in user scope, and only when using the `#:external-root-url` keyword
argument:
> (define x (xref-binding->definition-tag (load-collections-xref)
'(deta/query lookup) 0))
> x
'(def ((lib "deta/query.rkt") lookup))
;; works good:
> (xref-tag->path+anchor (load-collections-xref) x)
#<path:/Users/joel/Library/Racket/7.7/pkgs/deta-doc/doc/deta/index.html>
"(def._((lib._deta/query..rkt)._lookup))"
> (xref-tag->path+anchor (load-collections-xref) x #:external-root-url
"http://docs.racket-lang.org/")
. . ../../../../../../Applications/Racket
v7.7/collects/racket/private/kw.rkt:1393:47: path-element->string: contract
violation
expected: path?
given: 'up
Is this a bug? Or is there a way to make this work for user-scope packages
as well?
