Koreader running on Kobos (all of them, hopefully!)

Hi:

I have a question about setting margins. Is there a way to set the default margins for the "Small", "Medium" and "Large" buttons on the Page Margin section? I want to maximize my reading space and I like very narrow margins. I tried playing with the epub.css file, adding specific margins controls (eg margins: 0em 0.05em) and @page properties, but nothing seems to work. Is there a default setting some place that I can change the values of the above buttons? Under 'Set render Style' selecting clear still gives a default margin of about 1em. Also, I have pre-edited all my epub margins to reflect my reading style. All my epubs work great in Coolreader and nickel software (patched).

Thank you.

Look at here

-- crereader margin sizes
-- margin {left, top, right, bottom} in pixels
DCREREADER_CONFIG_MARGIN_SIZES_SMALL = {5, 10, 5, 10}
DCREREADER_CONFIG_MARGIN_SIZES_MEDIUM = {10, 15, 10, 15}
DCREREADER_CONFIG_MARGIN_SIZES_LARGE = {20, 20, 20, 20}

in koreader/defaults.lua .

Thank you Chrox! That did it! Well almost. Very strange, I set both left and right margins to zero (all of them actually, more on this later), and there is still about a 0.5em gap for both left and right margins. However, punctuation is allowed to use this 0.5em space. It is way better than what it was, so no complaints; I will play with the css options to gain a bit more, if possible. Caution though, if you set the bottom margin to zero you will loose the last line if you use the mini progress bar (progress bar covers 90% of the bottom line). If you select the full progress bar then all is fine, the last line is fine and you do not loose the top line (top margin set to zero). Bug?

(now press one time the hardware home button)

and share here this file we can test it with other devices

When I arrive at home I'll post the bin file to refresh my mini, but keep in mind that this file contains info about the touchscreen and don't work with resolutions higher than 600x800

so I guess no Touch user has tried it yet.
Just installed koreader on my Aura, and it is working very fine - glad to see the dictionary work in pdf files too :-)
Thank you all guys for all your work!

another remark about re-flowed pdf: in this book all the quotes are minuscule

screenshot from pc https://anonfiles.com/file/f40bb0d63...7bb678f05d0778

and when I try to increase the font to maximum just to be able to read the line, ko-reader crashes

using the new 6" kobo aura, build 2014.04-2

Is there a way to get standby/sleep to work with Koreader on the Aura HD? When I push the button for sleep, the word "standby" flashes on the screen by it stays on. The light turns off by I can still flip the pages. That might not use much power, but it's annoying because the pages turn unintentionally when I pick it up, touch it, whatever. Any known fixes for this issue?

What works for me is to change the timing settings in uimanager.lua, using Notepad++. The file is located at ./.kobo/koreader/frontend/ui/uimanager.lua.
Around line 300 you should see a "timeout=1" I change it to timeout=0. Then you should find another line like this: self:scheduleIn(0.5, function() Device:Suspend() end) I change it to: self:scheduleIn(2, function() Device:Suspend() end)

This gives me a suspend that is just a frozen screen that makes it so I can clean the screen or put my AuraHD in my pocket. I can check that it is working by poking where I would normally get a menu.

Sometimes, after along period of use I may have to restart Koreader for it to continue to work. Some others have tried this but they reported that it didn't work for them.

Luck;
Ken

EDIT: HOWTO install on your own AURA
Unpack attached zip-file to the koreader directory and add the line

cat kobohome.bin > /dev/input/event1

two times to the end of the shell script koreader_kobo.sh

HOW did I do it for other kobo's?

Okay, I had some problem getting it to work. First I only created zero byte files.

Then I used:

cat /dev/input/event0

and started to tap, but nothing happened. Then I used

cat /dev/input/event1

. It resulted in non-identical output for multiple taps:

Then I gave Pazos command:

[root@(none) ~]# cat /dev/input/event1 > kobohome.bin
^C

and it finally resulted in a non-zero file.

Then I adapted the shell script koreader_kobo.sh and added at the end twice the line

cat kobohome.bin > /dev/input/event1

The first line activates the top menu, the second line gives the home screen.

I've added an Aura Homebutton binary file.

Around line 300 you should see a "timeout=1" I change it to timeout=0. Then you should find another line like this: self:scheduleIn(0.5, function() Device:Suspend() end) I change it to: self:scheduleIn(2, function() Device:Suspend() end)

This gives me a suspend that is just a frozen screen that makes it so I can clean the screen or put my AuraHD in my pocket. I can check that it is working by poking where I would normally get a menu.

Sometimes, after along period of use I may have to restart Koreader for it to continue to work. Some others have tried this but they reported that it didn't work for them.

I made these changes and standby is now working in Koreader on my Aura HD. Thanks!

Thank you Marksimus, but I cannot make it work on my Aura. I am sure I must be doing something very basically wrong - since my koreader_kobo.sh file is in the .kobo directory, not in koreader, I added twice at the end of that file the following lines:

cat /koreader/kobohome.bin > /dev/input/event1
cat /koreader/kobohome.bin > /dev/input/event1

Have I made a mistake in directing to the koreader folder (where I have put the .bin file)?

(the reason I have koreader_kobo.sh outside of the koreader directory is because of a modification of the path to dictionary files, so that the modified koreader_kobo.sh file will not be modified every time I update the koreader version).

EDIT: you should use

cat ./koreader/kobohome.bin > /dev/input/event1

Before you looked for the nonexisting directory koreader in the root, while now you specify it as from the current directory ("./")

Interesing. I am not seeing anything wrong. However, why don't you follow along the steps and create your own bin-file.

If you're unsure how to get a command shell to issue the commands, then the fastest way is to use KoboLauncher for USBnet. The first time is the trickiest if I remember correctly, because you have to manually change the IP address of your koboreader. It appears as a --I believe-- NDIS Gadget. Select properties>Internet Protocol Version 4>Use the following IP address>IP address: 192.168.2.99. Done.
After that you can use Putty an telnet to 192.168.2.101 or WinSCP and FTP to 102.168.2.101. The user name is "root", password is empty. From WinSCP you can also lauch Putty during a FTP session.

@tshering, @enotar and @olobolger:

Could any of you Touch owners enable debugging with the "-d" flag after reader.lua in koreader_kobo.sh, start koreader and press the home button a number of times and post the resulting ev.log file? It would give us the event codes for the home button from which we could return to home screen after exiting koreader.

Rather nice would also be a binary file for the home button as generated by pacos' method.

The first result would allow us to return to the Nickel homescreen using koreader lua-code, the second would hack the koreader_kobo.sh script to do it quick and dirty.

Many thanks Marksimus. I have tried again with your correction, but it did not work. But adding two dots did, that is with the line

cat ../koreader/kobohome.bin > /dev/input/event1

I put the two dots only because the koreader directory is at the same level as the _Dict directory where the dictionaries are (I followed your suggestions here).

Anyhow, glad it works, thanks again for your help - I tried to make telnet work in the past, but that is above my (in)abilities...

Is it possible to have programmable tap zones, like in coolreader?

Yes, see lines 59 and further in default.lua.
