actually I got help in #cider channel. I was able to fix my issue

Found a problem with the desktop approach above (see 1/28) -- it reopens all buffers, even those which aren't currently displayed, so over time you build up a vast list of open buffers (all that you've ever opened since starting to use this approach, except any you've explicitly killed). I expect there's a reasonable workaround, but wanted to point it out in case anyone else has been trying this approach.

@eggsyntax one workaround i've employed around the general problem of lots of open buffers, is marking old buffers in ibuffer manually

(ibuffer :variables
                                                ibuffer-group-buffers-by 'projects
                                                ibuffer-old-time 8)

8 there is hrs, i think default is 72

Does marking them like that cause them to be automatically killed? If so, do you happen to know what the behavior is if a buffer has unsaved changes?

na marking just 'selects' them, similar to selecting by regex

then there's a separate command to close them, that confirms with you when there are unsaved changes

ibuffer-mark-old-buffers is the selection function

Excellent, thanks! Do you recall what the command is to then kill marked buffers? Not seeing one doing a quick search on kill-marked.

LOL

thx 🙂
