[Sk7Str1p3]

format json for better performance in editors and human-readability; add few steam games for detection on linix (wip)

[Covkie]

the detectable json is not manually written it comes from discords api

Then answer me. If they have shared database, why Discord can detect then I play Half-life or dota or CS or smth and arRPC is not?. And why arRPC can detect them to after my fix?

EXACTLY. I have to edit the detectable.json manually to detect some native linux games, which are detected fine with discord's closed RPC. The linux executable for native linux games like war thunder and dota 2 are not present in detectable.json.

I don't think discord uses the same file.
