Keep investigating. (I assume the problem doesn't arise with just Helm and PDF-tools (i.e., without Dired+).)
I will keep at it. No, I've used helm and pdf-tools together for years, and I only had the problem just recently when I started using dired+. Anyway, I'll do that "diredp-send-bug-report" you suggested as follow up, and maybe even open an issue with helm. I recently reported a helm issue and they literally fixed it by the next day. I was so happily surprised that I am now a patreon supporter!
I tried debug-on-entry before calling dired-jump and didn't see any errors. I am not sure if I know what I am looking at when I drill down to the active variables. As I mentioned, it is not completely frozen, it is just taking a very long time when there is a large pdf in the buffer, so it might not throw an error.
But I did do another test which seems to rule out helm in itself as the problem. In an emacs with no packages except pdf-tools and dired+ the same problem occurs in ido-mode, but NOT when simply using the default basic completion style. Ido-mode offers completion candidates, but just as with helm, when you try to go to a dired buffer, emacs hangs. With no dired+, the same operation in ido-mode works smoothly. So it seems the issue is being caused by dired+ in combination with not just helm, but ido completion. I could try other completion packages, I suppose, to see if those also have the same problem.
As I said, please follow up off list, using
M-x diredp-send-bug-report
. You haven't even mentioned your platform etc.One quick thing to try would be to evaluate this, to see if the extra font-locking is the problem:
(remove-hook 'dired-mode-hook 'diredp--set-up-font-locking)
.Sorry, last message here. I will follow up with diredp-send-bug-report. I will try your last suggestion.
Thanks!
