Previously, for images with no alt-text, the zoomed image wouldn't get
properly inserted. For images with alt-text, both the zoomed and
unzoomed image would be displayed at once (bug#71666).
* lisp/net/shr.el (shr-sliced-image): New face.
(shr-zoom-image): Reimplement using
'next/previous-single-property-change', and don't bother deleting any of
the text.
(shr-image-fetched): Clean up any overlays when deleting the old region.
(shr-put-image): Ensure we always have a non-empty string to put the
image on. For sliced images, just use "*", since we'll repeat it, so we
can't preserve the original buffer text exactly anyway. Apply an
overlay to sliced images to prevent unsightly text decorations.
(shr-tag-img): Move the placeholder space insertion where it should be
and explain what it's doing.
* test/lisp/net/shr-tests.el (shr-test--max-wait-time)
(shr-test-wait-for): New helper functions.
(shr-test/zoom-image): New test.
This directory contains source code for the parts of Emacs that are
written in Emacs Lisp. *.el files are Emacs Lisp source, and the
corresponding *.elc files are byte-compiled versions. Byte-compiled
files are architecture-independent.
The term subdirectory contains Lisp files that customize Emacs for
certain terminal types. When Emacs starts, it checks the TERM
environment variable to get the terminal type and loads
'term/${TERM}.el' if it exists.
The other subdirectories hold Lisp packages grouped by their general
purpose.
