KoboLauncher for standalone Qt apps

I'm not sure what I would do if I wanted to display a terminal on the Kobo screen... I can already display PNG images (pngshow, in my github) so maybe... run something in xvfb, take screenshots and display those?

You could run it in the browser with JavaScript (my WebPortal mod has some apps but no terminal really) but you'll probably get drowned in display refreshes...

Feels like a quite a hassle for such a thing, would be nice if it would be possilbe to compile and run qTerminal or something the like. Is it possible to run x11 applications on the Nook? How does nickel work? Is there a special type of framebuffer? Is it possible to run fbterm?

Hi: Would "sergeyvl12"'s kick-off to this thread, titled "KoboLauncher for standalone Qt apps," particularly the "Notepad," work on the "Kobo n416 eReader," aka Kobo 1st Generation, Original, & the one w/ Bluetooth (rather than WiFi)?
If not, could anyone point me to how I could install onto the Kobo n416 any small, simple text editor? (Notepad would be fine, but if any other such text editor could be more easily loaded onto the "n416" that'd be preferable given my newbie status, with thus particular kudos for a referral to step-by-step directions for doing this generally [&, if necessary or helpful specifically on a "Kobo n416"]).
Thanks in advance for any guidance you can offer.

P.S. Being a newcomer to this site, as well as a newbie, I've been amazed to see the extent of knowledge here, in addition to being impressed by the generosity those "in the know" are willing to be with aid & information for those not yet very saavy about this stuff.

1. Please stop double posting. It's very annoying.

2. As far as I remember, the non-Touch Kobos (the original you have and the Wifi) will not work with the add-ons coded for the later models.

Hi!

The following new apps are added to the latest build (2017.10.06)

1. Konsole - type shell commands and see results
2. Dropbox client (requires license key)

Hi, thanks for making a terminal. I have found one problem with it, I installed python on my kobo and when I try to play a simple command line based tic tac toe game with python like this, python /mnt/onboard/tictactoe.py it won't display the application. And then when I type a letter it quits the application and then shows the application in the history of commands you entered. But since it left the application I can't play it anymore. So the only way to get the konsole to show the application is to type in a letter, and the application doesn't recognize it as a valid symbol and quits. Then the application shows up in the history of the commands you entered. Is there a way to get it to display the application without quiting the application first? I hope you understand what I am trying to say. Attached are two screenshots.

SKK,

This is because python is running without tty and thus buffers it's stdout. Probably I can't develop real terminal emulator for kobo because it has limited kernel (without pseudo terminal support)

For now the only solution I have is to put these lines at the beginning of your script:

class Unbuffered(object):
def __init__(self, stream):
self.stream = stream
def write(self, data):
self.stream.write(data)
self.stream.flush()
def writelines(self, datas):
self.stream.writelines(datas)
self.stream.flush()
def __getattr__(self, attr):
return getattr(self.stream, attr)

import sys
sys.stdout = Unbuffered(sys.stdout)

return getattr(self.stream, attr)

import sys
sys.stdout = Unbuffered(sys.stdout)

Thanks for your help! I added that code but now it says unbuffered object has no attribute write. So I guess I will just have to give up for now on getting python programs to run on a kobo.

Edit: Actually I made a mistake in the spacing on the code. It doesn't give that error anymore when I test it on the computer. Now to test it on the kobo.

The code indented

Thanks alot everyone for your help! It works perfectly now on my kobo.

Can you please update the source code link? http://wiki.vlasovsoft.net/doku.php?...reader#license doesn't work anymore and I'd like to see with what options freetype is compiled and what version it is.

Thank you!

Thanks, updated. But to see with what options freetype is compiled and what version it is you need CR Engine sources. I've also added the reference to it.
