I may not have time to integrate this extensibly into the public-inbox
search engine today, but at least here is an NNTP article number to
Message-ID mapping for non-NNTP users:
I'm working on getting "gmane:NNN" searches working.
I'm deploying and reindexing this change to one of the onions, first.
So, to get article 123 from "gmane:123":
http://czquwvybam4bgbro.onion/git/?q=gmane%3A123
(%3A is the URI escape for ':')
For those unable to run Tor, you can also try using a Tor2web
proxy listed at https://www.tor2web.org/ For example:
http://czquwvybam4bgbro.onion.to/git/?q=gmane%3A123
Additionally, searching by Message-ID with the search box will
also work after the reindexing (instead of just using the
Message-ID in the URL):
https://public-inbox.org/meta/20160810232358.GA29130@whir/
After this is fully-deployed and working well; the plan is also
to be able to fix existing gmane links (and also handling
the $gmane/NNN links that were commonly used).
