Subject: shr.el: add linebreaks to mouse-over tooltips (title attributes)
Date: Fri, 12 Dec 2014 22:29:21 +0100 [thread overview]
Message-ID: <877fxwr1zi.fsf@topper.koldfront.dk> (raw)
When reading nntp+news.gwene.org:gwene.com.xkcd there are often long
title attributes on the comic image, and when shown on one line, the
text does not fit on my tiny screen.
I guess the correct solution would be for Emacs to wrap the "help-echo"
to fit the screen automatically.
The second best thing would be if shr.el wrapped the text to fit the
screen.
And here is what I crudely whipped up, a regex to sort-of-wrap at 72
chars:
--- shr.el.orig 2014-12-12 22:21:34.271477782 +0100
+++ shr.el 2014-12-12 22:20:44.652962400 +0100
