Re: notmuch-emacs inline image display broken in emacs-29
Hello Alex and David, I also came across this issue: inline image are not displayed only when `notmuch-show-indent-content` is non-nil. However, even when `notmuch-show-indent-content` is `nil` they are displayed but cannot be hidden. As Alex Murray pointed out, the reason is that the function `mm-insert-image` is being changed in Emacs 29 to use `insert-image` instead of `put-image`. `insert-image` inserts images using the `display` property of a whitespace character. The effect is that when `indent-rigidly` is called in `notmuch-show-insert-msg`, whitespace is removed and hence the image is removed. I've filed a bug#62637 on bug-gnu-emacs to discuss this. An easy fix in `mm-insert-image` is use non-whitespace character (the second argument of `insert-image`) so that it is not deleted by `indent-rigidly`. This change actually makes indenting images work in the new version. The other issue is that hiding an overlay created around such an image does not seem to work (see bug#62637 for a discussion). A way to resolve this is to add some whitespace (like a newline) inside the overlay before the image, which seems to fix things. -- Al ___ notmuch mailing list -- notmuch@notmuchmail.org To unsubscribe send an email to notmuch-le...@notmuchmail.org

I also tried the one in [1] and that did seem to help - images in replies (and hence emails that by default are displayed with an indent) show up now, but not for emails that are the first ones in a thread (and hence have no indent by default). (although I notice in a recent conversation in #notmuch that it did appear to work for one user - but not sure which patch they were using). Any ideas where I should start trying to debug this on my side? I am using a pretty recent build of emacs from master with a the latest notmuch-emacs bits from MELPA - https://melpa.org/#/notmuch (and the notmuch binary 0.37 - as packaged in Ubuntu 23.04 with version 0.37-1ubuntu3 FWIW). > [1]: > https://nmbug.notmuchmail.org/nmweb/show/20211214121726.2631714-1-da...@tethera.net > ___ > notmuch mailing list -- notmuch@notmuchmail.org > To unsubscribe send an email to notmuch-le...@notmuchmail.org ___ notmuch mailing list -- notmuch@notmuchmail.org To unsubscribe send an email to notmuch-le...@notmuchmail.org

I remember from last time I considered globally replacing our use of indent-rigidly [1] there were a few issues to be dealt with, but maybe this is a reasonable approach.

The image is actually inserted OK, but then apparently deleted by indent-rigidly (probably because it looks like whitespace). I tried replacing indent-rigidly with a simplified version the and that leaves the image inserted, but unfortunately doesn't indent it properly.

notmuch-emacs inline image display broken in emacs-29
Hi folks, I have noticed that inline image display doesn't work anymore in emacs-29 / git master and have tracked it down to a change to the way mm-inline-image inserts an image into the buffer. In https://git.savannah.gnu.org/cgit/emacs.git/commit/?id=d2186160a9e978960c0f96bc3b4fc65b5affc170 mm-inline-image was changed to use insert-image instead of put-image. This inserts the image into the buffer using a single space as the string contents with a display property set as the image contents so that the single space is not shown itself but instead the image is shown in its place. I had thought the culprit then was the use of notmuch-wash-elide-blank-lines within the default value of notmuch-show-insert-text/plain-hook - assuming that since the line containing the image is now just a single space, it then gets deleted from the buffer and the image is never shown. However, even after setting notmuch-show-insert-text/plain-hook to nil, images are still not shown inline by notmuch. However, if I locally redefine mm-inline-image to use say a period "." as the string argument to insert-image then the image appears as expected. Any thoughts on what may be happening here and how best to resolve this?
