Support overrides

[vixalien]

also move gobject.object overrides to new file
allowing to construct objects by extending the existing object

[vixalien]

This pattern is similar to what GJS does already, for example: https://gitlab.gnome.org/GNOME/gjs/-/blob/HEAD/modules/core/overrides/GLib.js

This PR also needs to get merged later, converting to draft.

@ahgilak, I believe this is ready for review. I would like to know what you feel about this. This will be the basis of other very cool stuff I'm working on, such as #23 and #20

[ahgilak]

Are you sure this is ready?
Everything seems broken.

[vixalien]

Hmm. I see the examples are not working. However, they are not working in the main branch either, so I think it's a regression I caused. I'm really sorry for this, and think it's time we added some tests.

[vixalien]

Wait. I see what happened now. I got errors while trying to execute the files in the examples/ folder, and it turns out they were using an older version of deno_gi because they got it from https://gir.deno.dev. Could you add versioning to the domain like it's done for https://deno.land/x? It may even be a good idea to make the site's code open source if possible.

This PR is ready for re-review, as it works, please let me know what you think.

Hmm. I see the examples are not working. However, they are not working in the main branch either

Only stylesheet.ts is broken on main, other examples are fine.

[ahgilak]

main purpose of gir.deno.dev is to add typescript definitions, besides that it only loads the library and nothing else.

you can test your local changes by adding the following deno.json file:

{
  "imports": {
    "https://github.com/ahgilak/deno_gi/raw/main/mod.ts": "./mod.ts"
  }
}

[ahgilak]

This is the error comes up while running the examples in current PR

error: Uncaught (in promise) TypeError: app.on is not a function
app.on("activate", activate);
    ^

[vixalien]

main purpose of gir.deno.dev is to add typescript definitions, besides that it only loads the library and nothing else.

Yes, I see. it can still get versioned right?

Only stylesheet.ts is broken on main, other examples are fine.

The fixes for that are in #26. Do you want me to include that PR in this one? I wanted to include it in a separate PR because it fixes more things than this specific issue.

[ahgilak]

Do you want me to include that PR in this one?

No I meant other examples are working fine on main branch, but broken in this PR.

[vixalien]

No I meant other examples are working fine on main branch, but broken in this PR.

Yes, I know :)

I was saying that that problem is indeed exposed by this PR, but the fix is in a separate PR because it handles other cases too of this bug. I will include the fix in this PR though, to streamline things.

[vixalien]

fixed everything. please take a look!

[vixalien]

Thanks!
