Backward scroll of beamer pdf slides creates stack of buffers #21

Closed averter closed 2 years ago

averter commented 2 years ago

This is a great package which works perfectly to visualize portrait oriented pdf files. However, when I try to use it on beamer landscape pdf slides, as soon as I start backscrolling (using the upward arrow key) this mode keeps stacking buffers on top of each other. Like so Untitled So my question is if there a workaround which does not interfere with the display of the portrait oriented pdf files? If needed this template can be used for testing purposes. Thank you in advance.

Thank you for your report. First, I am wondering which version you are using, as I think the latest version should never create new buffers. So I guess you are using some older version, I think in that version there is no easy fix or workaround for this.

However also the current/most recent version has quite some bugs, and does also not handle landscape pdfs correctly. I have been working on a little cleaner version in the continuous-scroll-version-3 branch of my pdf-tools fork, which should work a little better in general, but also that version unfortunately does not work (yet) with landscape slides.

Unfortunately, the Emacs display mechanism and the pdf-tools package are both quite complex and therefore, fixing any of the bugs takes considerable time for investigation and for implementing the fix. Unfortunately, I have no resources (time nor money) to work much more on this package so that I am unable to investigate this bug. On the other hand, I expect this would be one of the relatively simple to fix bugs and I could offer all my assistance. (Maybe when I have some more time at some point, I could create a kickstarter for this and try to find some sponsors...)

Thanks for your work and quick reply. Indeed, I have recently updated to the latest version and am experiencing the two issues reported https://github.com/dalanicolai/pdf-continuous-scroll-mode.el/issues/15 and https://github.com/dalanicolai/pdf-continuous-scroll-mode.el/issues/16. Probably this is due to the fact that I am using Gnu Emacs 27.2; quite different from spacemacs? I might revert back temporarily to the two buffers version until these issues are fixed, but in any case I will be following new developments closely. Thanks and closing for now.
