Unable to suggest mods correctly

[ZekerZhayard]

Considering the below two mods:

mod_a:

{
    "schemaVersion": 1,
    "id": "mod_a",
    "version": "1.0.0",
    "breaks": {
        "mod_b": "2.0.0"
    }
}

mod_b:

{
    "schemaVersion": 1,
    "id": "mod_b",
    "version": "2.1.0",
    "breaks": {
        "mod_a": "*"
    }
}

the result is:

[00:48:52] [main/INFO]: Loading Minecraft 1.18.2 with Fabric Loader 0.13.3

mod_b 2.1.0 is indeed after than 2.0.0

[Juuxel]

The suggestion is correct as far as I can tell. The "any version before/after 2.0.0" comes from mod_a exactly matching with 2.0.0 (so it's one of the two requirements here), and the other requirement is that it has to be compatible with mod_a.

Yes it is technically correct even if not the most human readable. The declaration in mod a effectively creates 2 open intervals with 2.0.0 missing, which is what loader requests (<2 or > 2)
