how do i force wrold setting via modmain asdsdf

[JohnWatson]

for instance i want my server mod to always be survival and have caves turned off regardless of the settings the user has set is that even possible

If i remember well, @Serpenswanted to do the same thing before, i don't know if he found a solution for this.

You can force the most settings within modworldgenmain.lua (create it in your modfile where also modmain.lua is).

There you add:

AddTaskSetPreInitAny(function(tasksetdata)
    if tasksetdata.location == "forest" then
        tasksetdata.overrides={
            world_size  =  "small",
            wormhole_prefab = "wormhole",
            layout_mode = "LinkNodesByKeys",
            season_start  =  "autumn",
            autumn = "veryshortseason",
            winter = "veryshortseason",
            spring = "veryshortseason",
            summer = "veryshortseason",
        }
    end
end)

I noticed you always have to include wormhole_prefab and layout_mode, otherwise game will crash. All other things are optionally. You can find the possible options here:
Don't Starve Together\data\scripts\map\customise.lua

Setting game mode and if caves should be active is a bit more complicated.
For caves I added this workaround:

        if tasksetdata.location=="cave" then
            tasksetdata.tasks = {"CaveExitTask1"}
            tasksetdata.numoptionaltasks = 0
            tasksetdata.optionaltasks = {}
            tasksetdata.set_pieces = {}
            tasksetdata.valid_start_tasks = {"CaveExitTask1"}
            tasksetdata.overrides={
            world_size  =  "small",
            wormhole_prefab = "wormhole",
            layout_mode = "LinkNodesByKeys",
            }
        end

This means, even if cave will exist, it will be totally empty.

The workaround for the mode was to let the game crash, if the wrong mode is active
 

if _G.TheNet:GetServerGameMode() ~= "adventure" then
    print("You have to choose adventure as game mode!! "..errortoabortgame) -- errortoabortgame is nil and can't be added to a string, it will cause a crash
end

From what I know you can't set the mode, but you can change the mode details.
So instead forcing to use survival, you can change any choosen mode to work like survival:
I copied this code somewhere:
 

-----------spawn mode------------------------------------------------
-- local SpawnMode = GetModConfigData("spawn_mode")

-- GLOBAL.GAME_MODES["custom_game"].spawn_mode = SpawnMode


----------ghost sanity drain--------------------------------------------
-- local GhostSanityDrain = GetModConfigData("ghost_sanity_drain")

-- GLOBAL.GAME_MODES["custom_game"].ghost_sanity_drain = GhostSanityDrain

-----------ghost enabled------------------------------------------------
-- local GhostEnabled = GetModConfigData("ghost_enable")

-- GLOBAL.GAME_MODES["custom_game"].ghost_enabled = GhostEnabled

----------------reset timer-----------------------------
-- local ResetTime = GetModConfigData("reset_time")

-- if ResetTime then
    -- GLOBAL.GAME_MODES["custom_game"].reset_time = { time = 120, loadingtime = 180 }
-- end

-------------------------poratl revival------------------------------

-- local PortalRez = GetModConfigData("portal_rez")

-- GLOBAL.GAME_MODES["custom_game"].portal_rez = PortalRez

-----------------banned items-----------------------------------------
-- local BanResItems = GetModConfigData("ban_rez")

-- if BanResItems then
    -- GLOBAL.GAME_MODES["custom_game"].invalid_recipes = { "reviver", "lifeinjector", "amulet", "resurrections" }
-- end
