Hi, let me start by thanking you for this wonderful piece of software! Immediately after I had started using it to read papers, I got hooked and can't go back now.

Currently, it is a bit tricky to install & upgrade it - one needs to set up the directory structure themselves and periodically overwrite its contents with the ones of the ZIP containing the new version.

An installer would help with that, while also lowering the barrier for adoption and opening possibilities such as installing & upgrading Sioyek via package managers, e.g. winget for Windows. The QT Installer Framework seems to be a good candidate for that. I'd love to see it implemented!

When scrolling to the right, the page is scrolled to the left and vice versa. If this was done consciously maybe consider adding an option to flip the direction of the horizontal scrolling.

I built from the current main branch.

On another note: Thank you very much for this program, using it already feels for me to be more efficient than other pdf readers.

When I middle-click on ... table x.y ..., ideally I should be redirected to the table x.y. But some books have both table x.y and figure x.y. The behavior currently looks arbitrary. Upon clicking a table, I was redirected to a figure with the same number.

Also, when I clicked on 3.4 (I was in chapter 13), I was redirected to 13.4.

I understand that you might be using heuristics when links are not provided, and they are prone to failures. Can you point me to relevant code files (or function)? I want to understand the logic and see what can be done to alleviate this kind of behavior. (Sorry, I was planning to peruse the whole code, but it seems daunting :) ).

Hi,

I am trying to install from source on Ubuntu 20.04 and getting the following C++ error in during compilation. Probably I am just missing some C++ library, or a compiler flag to conform to a recent standard is not being set in pdf_viewer_build_config.pro, but my Googling is not strong enough to figure out what it is.

Hello,
A cool feature that I find very useful in many websites such as ScienceDirect, Wikipedia(when using the wikiwand extension*****), etc. is that when you click on a reference number instead of jumping to the reference in the References section, it show a little pop-up notification showing the full reference.

IMHO, this is way better than using bookmarks, or portals.

*****Here is a screenshot from wikiwand, when I click on reference number 2, it will show the reference instead of jumping:

I downloaded both versions and see no difference. But maybe there is?

I try to highlight some sentences but when I use other pdf software (like foxit reader, chrome)to open it I can't see the highlight, but if I use highlight in foxitreader, it can still be seen in sioyek. Do I miss some operation like save the changes or pdf?

Hi there,
Thanks for the amazing project!

Built on Linux Xubuntu 20.04 from scratch using ./build_linux.sh and fresh master.

I've added highlights by selecting a piece of text and pressing h, so it turns to be colored. But when I pressed dh it does nothing, only invalid command; resetting to root in the logs.

If you need more info feel free to ask.
Cheers

Hello!
MacOS: 10.15.7
QT installed from home-brew: qt: stable 6.1.3 (bottled)
compilation fails:
Project ERROR: Unknown module(s) in QT: openglextensions
Any ideas how to troubleshoot?

How hard would it be to build for mac?

As far as I am aware, sioyek has only a continous display mode between pages, and there is no way to display document in a single-page mode which is very useful for presentations. In Zathura pdf viewer, you can achieve that by pressing "F5" key and use the "Page Down" or "Page Up" keys to navigate (which is a partial solution, for details, see this page).

Is it possible to have at least a similar behaviour for presentations mode?

Thank you

First, thanks a lot for this amazing piece of software! It really outshines other viewers for consuming papers/textbooks.

I wanted to put in a feature request for supporting scrolling with touch drags. Currently, if I drag on the touch screen, it simply behaves the same as mouse dragging with left button clicked - selecting all the text in those parts.

This is how the Edge browser (and Android touchscreens) behaves:

1. "Simple drags" scroll the document,
2. "Long presses" select the word under the finger (in sioyek, it currently acts as right click), and give handles which can be dragged to extend the selection.
   • This seems difficult to implement (especially the handles), so as a first approximation, we could instead do what the current "simple drag" does - after long press, until finger is lifted, select all the text that is dragged over.
3. "Two-finger press" acts as right click

Please make it available on Linux! Thanks!

One feature of Zathura which I use a lot is the ability to follow links from a hotkey - the way it works is you press a hotkey and visible pdf links are highlighted and given a number. Typing the corresponding number to a link then makes the viewer follow it.

Would it be possible to get functionality similar to this in Sioyek?

It's common to read multiple PDFs at same time. How can I change the behaviour to "Open this file in new instance" instead of reusing the same process?

Thank you

I opened a 98k pdf and I opened Task Manager / Processes under Windows 10
It uses 296MB of memory! while this is only 96kB for Summatra!

Would you please have a look!

Hi,

Would you be interest in Sioyek package as Flatpak.
I am trying to build it as Flatpak, but got the error

make: g++-9: No such file or directory
make: *** [Makefile:1037: book.o] Error 127

I think this is because flatpak use gcc 10.2.

Hi, I'm switching from Okular to sioyek, and this is a useful function in Okular I wish sioyek could have.

Please let me demonstrate what I mean with this screenshot

Besides, I have a question for @ahrm : Would you like to create a roadmap issue and share your plans about further development plans? Including new format support or code refactoring? (Right, I admit that I've read all open issues for sioyek)

Thanks for providing a Linux build. However, the current version seems to fail to render any PDF file I throw at it with following error:

qt5-3d 5.15.2

Arch Linux 5.12.15 x86_64

Hi. The features look awesome, so I tried to install the viewer.
I did:
sudo apt-get install qt5-default libharfbuzz-dev
So :

> qmake --version
QMake version 3.1
Using Qt version 5.12.8 in /usr/lib/x86_64-linux-gnu

But the build is failing:

I googled the error and tried to do sudo apt install qtdeclarative5-dev, but the build is still failing with this message:

How should I install Qt5 properly? Sorry for noob question, haha

Please ignore this issue. It does not exist.

In zathura (which this project seem to draw some inspiration from?), one has the ability to not only use the shift and ctrl keys as modifiers, but also the alt key. Any chance this modifier could be added to the existing roster?

In zathura, the way to configure such a keybinding would look like this:

goto_page_with_page_number		<A-g>

When opening a pdf file, or scrolling down, a black-white chessboard would appear on the screen

Other PDF readers like Okular would present a white (background colour) page while loading. The chessboard image would make my screen blink and my eyes are complaining about it.

Thank you.

This is what the text looks like with 125% scaling enabled on the display:

The issues weren't present at 100% scaling. I'll try with 150% and 200% too see what happens.
EDIT: Here's 150% and 200% scaling. Rendering is broken in both cases (need to zoom in a bit to notice in the case of 2x scaling, but everything seems aliased):

For reference, here's 1x scaling (no aliasing at all):

• OS: Debian 10.x buster
• Version: v0.31.5
  • https://github.com/ahrm/sioyek/releases/download/v0.31.5/sioyek-release-linux-portable.zip
  • https://github.com/ahrm/sioyek/releases/download/v0.31.5/sioyek-release-linux.zip

Actual behavior

Seems like both AppImages created on Linux distro which has more recent version of libstdc than actual LTS release

$ ./Sioyek-x86_64.AppImage
./Sioyek-x86_64.AppImage: /lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.26' not found (required by ./Sioyek-x86_64.AppImage)

Expected behavior

It should run without issues on Linux LTS distributions, so if possible use build environment which would allow use AppImage on LTS releases of both Ubuntu and Debian.

This is a useful tool. Could you add the function for which we can double click left mouse to select the single word or tell me how can I do about it.

Hi,

Many thanks for this great tool. It quickly became my favorite pdf reader.

What I would like to know is where the highlights and other file-related information are stored. I am trying to avoid losing it in case I move files or update Sioyek. Also, I would like to eventually export highlights and bookmarks.

Cheers

Hi,
After playing with Sioyek, it appears that it allows multiple duplicate hughlights, for example you can press:

hkhkhkhk

This will create the same highlight 4 times.

These duplicates appear also when you export them.
So I wonder why Sioyek allows this? is it a feature or a bug?

Thank you

Probably hard to debug, but not a single one of my pdfs seems to render. I can interact with the menus in sioyek just fine, and even navigate to different pages, but whatever I do, there's no actual rendered output. To give a visual impression:

It seems like no interesting errors/warnings are shown on the terminal. Still, here is an example of the information that is displayed when opening a pdf:

Version information

I'm using a sioyek build from the newest git commit (by way of the AUR package), which would be bf48fc4.

I'm using Arch linux (so everything should be at its newest possible version), with kernel version 5.14.5.

Pretty much the title. Or it would be also great to let the color be configured manually.

Hi, thanks for this project – seems to be scratching many long-standing itches!

Does the app look for config files in the usual Linux/Mac directories such as .config/sioyek etc? If not, could it?

Thanks!

Thank you for the program. It is easily the best pdf viewing experience I had. Please consider supporting CBZ and CBR files which are the standards for digital comic books.

Hi, is there a support to put comments to PDFs, or the plan to add this functionality?

Title says it all I think? Currently, the only way to get into dark mode is by a keypress.

An hacky work around would be to change the value of background_color to be dark. I'm okay with this, but the documentation on what the three values this option takes leaves me, well, in the dark. Are they R, G, B or something? Perhaps add that info to a comment in the prefs.config file?

This would be a very nice and intuitive QoL upgrade. Currently it's not clear what the tab key actually does in this list.

The default binding shift-o, as well as no custom bindings, no longer seem to pull up the files list.

On Linux, I have transparency+blur enabled on my compositor (OpenGL+KDE), and looks like sioyek also uses those values for the background. This is what happens when I enable dark mode:

(this looks pretty cool, to be honest)

There are some other rendering bugs too, probably related:

dark mode disabled, nothing visible

this is an artifact of the screenshot app, much more was visible on screen

Many STEM related ebooks are in DJVU format and I highly recommend adding support. And if you are going to the trouble to adding DJVU support, might as well add ebook as well.

Hi, thanks for the great project.

I've been using the viewer in Windows (and it works great :D), I find it a little inconvenient whenever the file I viewed the last time doesn't exist at the directory it was originally located at (which is often my scenario), the binary doesn't launch at all.

Could you consider adding a default action for the invalid last document path?

Thanks in advance!

1st Steps
There's projects that have made commenting on pdf a business. I need to dig up the link.
I think one step you could explore (not immediately on a rainy day) - is to show a list of what people are reading using opt in telemetry data - maybe using google sheet - something simple that you could set and forget without too much overhead - and then come back in 12 months and be like - let's take another step -
you might find it catches on - and you could have millions of users.
it would take a sign in process - a backend - maybe just firebase. and then a simple post to a worksheet.

I browse papers all the time - I gravitate to youtube to get help reading them as the linear algebra is quite advanced.
There's an opportunity to connect people - with papers - and have them help each other. But first step would be take a look at the data / and make it public from the outset. (you wouldn't want to expose emails / but you could just have a list of papers...)

Hi there,
Thanks for the amazing project!

I've tried to test it on Linux Xubuntu 20.04 by building from scratch using ./build_linux.sh.
After I started and play a bit with steps in the tutorial, I reached the line with backspace, pressed on it several times and the whole document turns into a white screen. So, I was not able to navigate it somehow, but I was still able to open a new document.
When I tested the same behaviour on the newly opened documents the issue reproduced.

Ask me any questions to help you reproduce and fix it!
I'm really excited to have such a nice thing in my toolbox.

The horizontal scroll wheel on my mouse (Logitech MX Master 3) scrolls vertically. I'm on Linux with Wayland (in case its relevant).

It would be nice if it has annotations like Adobe Reader/Okular.

Currently, When you press End key it will show the top part of the last page (correct me if that's wrong) so If I want to to reach the true end page I still have to press the "down" arrow key multiple times to achieve that.

I wonder if there is an option in Sioyek to allow this behaviour (in parallel with the current bahviour, or maybe allowing to override it).

Thanks

First, congratulations with developing something that immediately looks very promising as a PDF reader for scientists! It seems you have already implemented a lot of novel and very interesting features.

I'm the developer of a Vim plugin for writing LaTeX: VimTeX. If (and when) you think this viewer is suitable for working with PDFs generated from LaTeX e.g. with synctex support, I would be happy to add sections for how to properly configure Vim with VimTeX to use this viewer. Perhaps also add a full layer similar to what I've done with Skim, Zathura and MuPDF.

Let me know if you are interested in a collaboration for this type of direction; and of course, feel free to close the issue if you think this is better addressed by others/the community/at a later time/...

I believe this is the conventional way of doing thins. '=' should reset page zoom level to max with white margins.
Only '+' should zoom in the page.

When I try to open specific files with the Sioyek Appimage it immediatly crashes:

I have narrowed the problem down to mutated vowels.

The name of the file was: "Schönleber Verfahren zur Charakterisierung des Niederfrequenzverhaltens von.pdf"

changed filename : "Schonleber Verfahren zur Charakterisierung des Niederfrequenzverhaltens von.pdf"

since I changed the filename, it didn't crash anymore

Hello,
I would like to thank you for this piece of software: very helpful!
However, AFAIK, Most researchers are using some tools such as Mendeley to manage their documents/citations, etc.

Personally, I find it hard to transition from Mendeley to Sioyek and give up all the notes/highlight of each paper in my database of papers.

So, if Sioyek offers a solution to this problem, a lot of Mendeley will happily transition but It is still not clear how given that sioyek is not a library management software.

Isn't that possible?
Thank you
