Use a pattern'ed URL to fetch the latest version.

Hello there!

I would like to add RetroArch to Obtanium - but don't really know what the best way would be.

Their releases can be found here: https://buildbot.libretro.com/stable/

Technically, the URL pattern would be https://buildbot.libretro.com/stable/{VERSION}/android/RetroArch_aarch64.apk
But I don't know how I can make Obtanium query the versions found in the stable folder, as it is rendered in HTML. And the JS query for it isn't that nice either: Object.values(document.querySelectorAll("#items li.item.folder a span.label")).map(e => e.innerText)

Do you have an idea how I could make that work? Their F-Droids builds basically don't exist.

Thanks and kind regards,
Ingwie

I was able to add RetroArch to Obtainium using the following settings:

Field	Value
App Source URL	https://retroarch.com/?page=platforms
APK Link Filter	buildbot\.libretro\.com/stable/((:?\d+\.)*\d+)/android/.*\.apk$
Version Extraction RegEx	.*/stable/((:?\d+\.)*\d+)/android/.*
Match Group for Version Extraction RegEx	1
Filter APKs by RegEx	\bRetroArch_aarch64.apk$

The settings that I have not mentioned I left at the default values.

Let me know if it doesn't work for you.

Ok - now all I have to do is figure out how to copy all the RegExes into the app... because I am definitively not copytyping this by hand. I am visually impaired, errors are a guarantee with this xD

Thanks a lot, I will see if I can make scrcpy work and see if I get some form of clipboard sharing working... this should do the trick.

Yay for copypasta, "Note to self" channel in Matrix, and the fact that a Pixel Fold can run two things on one screen. Phew, got this done, and it worked! I did, however, get a message about the origin being retroarch.com but the actual source being buildbot.libretro.com. But aside from that, it pulled the correct version immediately and installed just fine.

Thanks for your help!

You're welcome :)

Just as a side note, Obtainium will return the whole message about origin being retroarch.com and source being buildbot.libretro.com every time you update the app. It's not an error, just a warning in case something messed up during the configuration or something changed in the webpage structure itself later on.
