08:02 <lukego> I'm adding CLIM support to SLIME. Just been tearing my hair out for hours wondering why images in Emacs don't react to mouse events where there are presentations. Just realized that it does work in isolation but somehow gets suppressed when the images are inserted into the SLIME REPL. ouch :)

09:20 <luis> lukego: hmm. presentations inject a keymap property into their region

09:22 <lukego> I've narrowed it down quite a lot now actually. It seems to be an issue with the string object containing SVG data. Specifically, my properties don't work if I use STRING, but do work if I use (substring-no-properties STRING). Weird. Checking now if there indeed are any properties and if so why Emacs cares.

09:24 <lukego> The string does not seem to have any text properties so I wonder if it's somehow about the identity of the string object itself.

09:27 <lukego> It's the identity of the string object. (The string doesn't have any properties.) I've no idea why... but I guess since Elisp strings are mutable there are any number of potential reasons. Just doing (create-image (copy-seq string) ...) fixes it.

09:27 <lukego> That took me a whole day to track down...

10:23 <luis> 🤷‍♂️

11:35 <lukego> hacking and slashing onwards, have presentations acting mouse sensitive now https://imgur.com/a/PjGomSs

13:42 <luis> Nice. Will you show this today or tomorrow in an ELS lightning talk perhaps?

14:29 <lukego> oh is that open? that would be great

14:29 <lukego> I'll look into it
