Counting entity's tags

[Muche]

Since there is a hard limit of 31 tags that an entity can have, is there a better way to count them than this (I am trying not to exhaust them all):

local function GetTagsCount(inst)
    if inst == nil or inst.entity == nil then
        return 0
    end
    local ds = inst.entity:GetDebugString()
    if ds == nil then
        return 0
    end
    local tagsstr = string.match(ds, "Tags: ([^\n]+)\n")
    if tagsstr == nil then
        return 0
    end
    local tags = string.split(tagsstr, " ")
    local tagscount = #tags

    return tagscount
end

Great! I thought that there is no way to list all tags.

It seems this way of listing tags works only on host/server, not on client.

Part of log from c_dump() on the server:

part of log from c_dump() on the client (of the same sign):

I have no idea what those FROMNUM mean, but they hide true tags. Looking at the sign (thus running inst:HasTag("inspectable") somewhere in playercontroller.lua/playeractionpicker.lua I guess) reveals it:

GUID:101816 Name:  Tags: _writeable inspectable writeable FROMNUM FROMNUM FROMNUM structure SnowCovered blocker

I think that "FROMNUM" means that there is no info about tag name but there is info about tag hash. So you can check inst:HasTag(tag_name) even if there is no real tag name in memory.

Tags are network synchronized. But inst:AddTag("my_tag_name") on the server won't send string "my_tag_name". It will send only hash of this string instead.

Also there are real names of tags if there is inst:AddTag before inst.entity:SetPristine() in prefab. Those tags are initialized on client.

However, it seems tags are case-insensitive, c_sel():HasTag('CanLiGhT');c_dump() just produced
