Yes, both work.

Yes, I can.

You should. And more generally, you should let scripts write to /tmp/nickel-hardware-status when Plato is running.

By the way, if you're trying to prevent every write to the FIFO, you've missed one instance in /etc/udhcpc.d/default.script.

I wanted to mention that mupdf's CSS engine supports @font-face, so you can change the default font via user.css, e.g.:

@font-face {
	font-family: Libertinus;
	src: url("/mnt/onboard/fonts/Libertinus Serif-Regular.otf");
}

@font-face {
	font-family: Libertinus;
	src: url("/mnt/onboard/fonts/Libertinus Serif-Bold.otf");
	font-weight: bold;
}

@font-face {
	font-family: Libertinus;
	src: url("/mnt/onboard/fonts/Libertinus Serif-Italic.otf");
	font-style: italic;
}

@font-face {
	font-family: Libertinus;
	src: url("/mnt/onboard/fonts/Libertinus Serif-BoldItalic.otf");
	font-weight: bold;
	font-style: italic;
}

body {
	font-family: Libertinus;
	text-align: justify;
}

To the moderators: could you replace " — " by ": " in this thread's title?

I can now confirm that this has to do with mupdf's memory consumption.

Opening an 80 MiB ePUB within Nickel consumes 7 MiB of RAM.

mupdf on the other hand, consumes 272 MiB of RAM after opening the same ePUB!

I've just released 0.3.3.

This release fixes a few bugs and generates notifications for some of the commands/services.

The framebuffer rotation workaround was removed from the KSM launcher. I hope this will allow @tshering to write a wrapper for this script.

Just updated to 0.3.3 and run into the following issue (from crash.log):

Plato is running on a Kobo Glo HD.
The framebuffer resolution is 1072 by 1448.
error: cannot open icons/check_mark-small.svg: No such file or directory
thread 'main' panicked at 'called `Option::unwrap()` on a `None` value', /checkout/src/libcore/option.rs:335:20
note: Run with `RUST_BACKTRACE=1` for a backtrace.
Aborted

After copying the icon from github, the error is just:

error: syntax error after attribute name
thread 'main' panicked at 'called `Option::unwrap()` on a `None` value', /checkout/src/libcore/option.rs:335:20
note: Run with `RUST_BACKTRACE=1` for a backtrace.
Aborted

Thanks, I forgot about this icon: it's used by the battery indicator.

I've updated the package.

I can't reproduce.
This error comes from mupdf's XML parser.

Before you try the updated package, could you replace

./plato > info.log 2>&1 || mv info.log crash.log

by

RUST_BACKTRACE=1 ./plato > info.log 2>&1 || mv info.log crash.log

in plato.sh and repost the content of crash.log?

Sorry, doesn't work. After trying to start plato like this, my reader gets unresponsive and I have to force a reboot (info.log is not moved to crash.log and doesn't include any backtrace).

I've wiped the plato directory and re-installed the updated package. Now, everything works fine again.

First of all, thanks for the software, it feels really fast and nice.
I've got a problem on Kobo Glo (regular one, not HD) though - I'm completely unable to call the main menu, when I press the hamburger button nothing happens. All the other buttons, like frontlight, working great.

Also, as a non-important suggestion, I'd personally like to have a way to customize "Powered off" screen with our own pictures and/or book covers.

P.S. By default it doesn't support FB2 for some reason, but when included to settings.json - discovers and reads them just fine, but seems to not be able to recognize the author.

My pleasure.

This has already been reported by tshering and I will provide a custom build that write every event on standard output in order to better understand what might be happening (I think it might have to do with the jitter tolerance of the tap gesture).

This will come.

FB2 wasn't included in the default list of allowed kinds but will be in the next release.

Right now, the metadata import isn't done by Plato itself but by the importer which requires a certain amount of involvement to build. Now that the menu view is finished, I might create menus for retrieving metadata through Plato.

I have attached a debug binary to this post, that print every event to standard output and has a relaxed tap jitter tolerance.

Please provide the content of info.log after having:

• Tapped the main menu icon.
• Tapped the Sort by: ... menu label.

[AlterusPrime]

Alright, here we go. What I've done was press "Sort by" first, then pressed again to close it. After that I've tapped main menu button twice and closed the program by holding power off button on my device.

[baskerville]

Did the main menu showed up?

The first thing I'm noticing is that there's a discrepancy between the device resolution defined in device.rs and the actual framebuffer resolution.

[AlterusPrime]

No, the menu doesn't show up at all, but Sort By menu does.
