Brief explanation of the change

Hi 👋
This adds rules for detecting GDevelop (both for GDevelop 5 and GDevelop 4).

This detects /node_modules/moment/locale/gd.js

[xPaw]

And some of the games you linked don't have any gd files in it, so that sucks. Any ideas?

[4ian]

Can you list the games that don't have these files?
GDevelop 4 games will have (lib)GDCpp.so/dll/dylib.
GDevelop 5 games will have gd.js - but I'll try to find another file (I guess we can't have a way to require the presence of multiple files/multiple regexes to pass?).

First two links.

It is possible by writing custom logic in the php file, but it is preferable to avoid that.

Thanks!
Seems like the first game is using the Electron Asar feature (https://github.com/electron/asar) so files are packaged in a .asar file. Unsure if this can be worked around (this would need the rules to be able to unpack asar files) - this is probably hiding a few other technologies (PixiJS, maybe Construct, other HTML5 game engines) behind Electron container only.

I've not checked the second game but seems it's not on the Steam store anymore (replaced by the author by a not yet released full version, while this was a demo).

Fair enough, I can suggest spriteruntimeobject-pixi-renderer.js instead of gd.js then, which should be unique enough (quite specific, using an odd casing that is unlikely to be reproduced manually, and used in all GDevelop 5 games).
Won't help with games using asar achives, but still should not give any false positive.
Let me know what you think!

[xPaw]

There are no depots that have a spriteruntimeobject-pixi-renderer.js file in them. If they're all packaged, unfortunately we can't access the files inside the package.

Thanks for checking, I was assuming Electron would not package files by default - my mistake. Seems like there is no obvious way then to check for the engine. I'll see if we can make this obvious with a specific file in a future version then.
