Aura H2O Starting in kobo developing

[Zinco]

Hi everyone, I'm not an expert in developing (I created 2 apps with python for android with Kivi) but now I wanna start create a my software in a Kobo Aura H2O. I'have read about NicketTC and NickelHook for creating app for Kobo devices, but i haven't understend how work these.
Someone can explain me, in simple words and with a list of step how I can create the setup for start? Thanks so much!

NickelHook relies on a particular toolchain (NickelTC). It is used to develop mods that work on Nickel (the blob that runs on your kobo, a qt app).

For standalone apps (ie: apps where you kill nickel before launch and restart nickel after exit) NickelHook won't work.

For standalone apps there're plenty of ways to develop. I would suggest to give it a try to fbink (as a binary and as a library) to simplify EPD stuff.

If you want to do your own EPD routines have a look at Plato (KOReader works the same way but the device abstraction is splitted across multiple repos, so it isn't as intuitive to read that code).

Just browse back through the Developer pages to find a project or topic that's helpful.

For example, on python you would find about projects like:

https://github.com/Mavireck/Python-S...er/tree/master

https://github.com/SheepWizard/kobo-minesweeper

https://github.com/Slalamander/inkBoard


Similarly, you could find rmkit for C++, go-fbink for golang, plato for rust, chroot for anything, etc...


If you want your app to run on your Kobo ereader, your Android phone, AND your linux desktop, check out the portability phenomenon that is KOReader. Download this calculator plugin and prove to yourself it works AS IS on all three platforms:

(I "made" an instant app by copying this philosopher app and changed it to a "ConfuciusSay" joke app, just by changing the text file and a couple of lines. You can make your own, e.g. "BruceLeeSays", "AristotleSays", or whatever!)

Note: If your app has simple GUI requirements like this, you could just implement it as a script in KOReader terminal, or invoke from a Telnet/SSH client. (Or if you install Kobo WebPortal, you could invoke script from remote web browser.)
If not too interactive, you could invoke the script from NickelMenu, with the script directly calling the fbink lib, mentioned by previous commenter, for output (install NickelDBus as well if more user interaction required.)

* There have been brave souls venturing into NickelHook programming, but I believe that has portability and maintenance challenges to go with the learning curve. It is nice to let the OG gurus do that heavy lifting.
