I use pdf-tools for reading and recently started using bookmark+ and dired+ for navigating. Unfortunately these two great packages seems to conflict.
One of the issues I noticed was that the bookmark+ command for bookmarking a pdf location in a pdf-tools buffer didn’t work; it gave an empty buffer warning. Turns out bookmark+ creator Drew Adams had already suggested a workaround which I discovered here: https://emacs.stackexchange.com/questions/72786/bookmark-plus-and-pdf-tools-pdf-view-error
So that solved or at least patched that issue. But then I noticed that with dired+ installed and any fairly large pdf opened in pdf-tools, emacs will freeze if you attempt to do dired-jump or helm-find-files. Dired-jump without dired+ is not affected by the size of the pdf at all and just opens the underlying directory immediately. But with dired+ anything above about 1mb or so hangs it for quite a while, anything around 10mb or more just freezes it for minutes on end to the point that unless you want to go make yourself lunch and coffee, you will have to force kill emacs to keep working.
As a noob, non-techie, non-developer, I just wanted to ask, what is the right way of asking about possibly getting this issue fixed, because I love these two packages and would love to have both in working order, but obviously don’t have the coding know how to do it myself. Of course if anybody knows of a fix that’s already out there for this issue, I’d love to know about that as well.
I’ll try that. Thanks. I just tried your suggestion of emacs -Q and that revealed something interesting, which is that with just pdf-tools and dired+ loaded, jumping to dired works fine. But then I installed and activated helm and then the problem of freezing appears. So it seems to have something to do with using these 3 packages together.
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!
