Add WebOS platform port

[SankarRealm]

WebOS port

Adds native webOS support to Butterscotch.

Features

• Native webOS SDL2/OpenGL ES backend
• ARM EABI5 build using the webOS SDK
• Controller and analog stick support
• webOS build instructions
• Ares IPK packaging/install workflow

Testing

• Builds successfully with the webOS SDK/webOS Brew SDK
• Tested on webOS 23

Known issues

• Controller required
• The B button currently triggers the webOS Back action
• Further controller/game testing is needed

Development note

This port was developed with significant assistance from ChatGPT as a proof of concept. It was used to help understand the existing platform ports, adapt the code to webOS, troubleshoot the webOS SDK/CMake/toolchain, and debug the implementation.

All new ports should use the new system, look at the vita port for reference.

will do, thanks.

Will running the build for webOS with the toolchain just spit out an IPK?

Add a CI workflow for it

Packaging it as an IPK requires the Ares tools

I'm trying to push a CI workflow to your remote branch

do I need to give you any permissions to the branch?

[cobaltgit]

"Allow edits from maintainers" option?

what does this mean though?

So far so good, you able to test the ipk that the CI workflow outputs? I don't happen to have any webOS TVs or whatnot

yup all good it ran. Can i add my own readme in src/webos like basic stuff on where to keep the game files and the app's location in the device.

What do you wanna add? I can help put it in when it's merged in the notes section for the webos platform download

Just add an entry to the consoles table in the readme that has your required info, right below vita and switch.

[cobaltgit]

Upstream merged, you can do that now, probably do it in the Other table?

[cobaltgit]

Yay, gets my seal of approval

[cobaltgit]

Are you compiling against SDL-webos?

[cobaltgit]

Got me thinking about porting this to Tizen..

[SankarRealm]

Are you compiling against SDL-webos?

yes mine came with webosbrew sdk and the version matches....so i guess

[cobaltgit]

Ah okay, just wondering about that b-button issue. Seems you need a partner cert to build native libraries on Tizen, so best we could do is base it off the webassembly port

Im sure it would work as far as I know tizen's sdk provides sdl2, but idk how compatible it is.

in case of b-button i was too lazy to fix and we can map other buttons inside the game anyway so I thought I would work on it later. haha im sure webOS allows anything then.
