Subject: 25.0.50; Command that returns URL to current Info node on the web
Date: Sat, 6 Dec 2014 11:37:47 -0800 (PST)

This is an enhancement request.  See this emacs-devel post and its
(short) followup:

http://lists.gnu.org/archive/html/emacs-devel/2014-12/msg00624.html

The idea is this:

The Emacs, Elisp, and Emacs Lisp Intro manuals are mirrored by GNU on
the web, and one version of the manuals uses a separate HTML page for
each Info node.

The request is to have an Info-mode Emacs command that returns the URL
of the GNU web page that corresponds to the current Info node.  For
example, if I am in (emacs) `Mark' and I invoke the command then it
returns the URL
"http://www.gnu.org/software/emacs/manual/html_node/emacs/Mark.html".

Among other things, this would facilitate pointing users from email or
from other web pages (e.g., Stack Exchange Q&A) to a particular manual
page on the web.

From a connected communication on bug-texinfo <at> gnu.org in a reply from
Karl Berry:

It would seem that such a file database would come in handy for
jump-starting this feature.
