Is there an option to say a URL starting with '//' and then having a proper hostname is not broken? #173

Closed vvdwivedi closed 4 years ago

vvdwivedi commented 4 years ago

I am getting a lot of URLs like these reported as broken:

//www.google.com
//fonts.googleapis.com

But these seem to be valid URLs when rendered in the page and nothing is broken because of that. I am not sure of the exact technical term, but I think these are scheme relative url strings https://url.spec.whatwg.org/#scheme-relative-url-string

I noticed that you have a package isurl and there is a lenient way of checking for valid URLs. Not sure if these URLs are reported broken because of the test by isurl, but if yes, can we add an option there to allow such urls?

Environment:

Is it solved with the master branch (unreleased v0.8)?

vvdwivedi commented 4 years ago

Haven't tried with master branch, just the released version. Will test with master branch and confirm by today.

vvdwivedi commented 4 years ago

Here is what I tested. I built from master branch and ran bin/blc https://pg.vvdwivedi.com/broken-links.html

//www.google.com → https://www.google.com/ OK www.google.com → https://pg.vvdwivedi.com/www.google.com 404

Looks fine to me.

vvdwivedi commented 4 years ago

Yes, you are right. Got a little confused there. The new version is fine.

After a quick run on 0.7.8 and 0.8.0, got following results:
