Subject: bug#77314: [PATCH] Gnus HTML washing: Allow href surrounded by single-quotes
Date: Thu, 27 Mar 2025 11:47:51 +0000

[Message part 1 (text/plain, inline)]

Gnus, both in the version of Emacs I use locally, and in the development
repository, has the following in gnus-html-wash-tags
(lisp/gnus/gnus-html.el):

    (when (string-match "href=\"\\([^\"]+\\)" parameters)

This, in turn, makes it so that, at least when this function is involved
with displaying HTML parts, links that have single quotes surrounding
their target in the code are not linkified in the article display.

I noticed this when reading RSS/Atom feeds via feedbase.org, which uses
single quotes for the link associated with each post, as opposed to
Gmane's Gwene (which does not show this issue and uses double quotes for
said links), in an instance of Gnus which is using

    (setq mm-text-html-renderer 'gnus-w3m)

The attached patch has the modification that fixes this for me locally,
applied to git HEAD; please let me know if something should be done
differently.

For further context, check the subthread on the gmane.discuss group at
news.gmane.io (over netnews) starting at [1], especially [2] and [3].

The patch is almost identical to the change mentioned in [3], but does
not escape the second ' in the new regexp.
