Need a clearAllMapData() function

[vadi2]

Need a way to clear all of the map data so people can start with a blank map if they wish.

This can currently be accomplished with a lua command loadmap("X") where X = non-blank string that is NOT an existing file name, I tend to use "_"!

Note that an empty string is a special case that loads the most recent profile saved map so does not work here.

[vadi2]

That sounds like a dangerous bug in that function actually, that if you give it an invalid filename the sideeffect is unintended data destruction!

[SlySven]

Well, the intended effect is to replace the current map with a new one and part of that process must be the removal of the old one - should that fail a repeated use with no/an empty string will reload the last saved one which does seem a reasonable recovery path even if that is not ideal behaviour. At present we can only hold one map in the system at a time!

{A multi-map capable Mudlet is somewhere on, but nowhere near the top of my wish-list with an ability to copy rooms and exits from one to the other - as sharing maps and importing modifications from collaborators does not currently seem easy...!}

[vadi2]

Even updating from IREs maps presents a challenge as that wipes all custom work.

[vadi2]

We don't have to use just last saved one - we can save right before loading into a temporary location. That way data loss would be minimised.

I think you can add an alias with this lua code :

for id,name in pairs(getAreaTableSwap()) do
  if id > 0 then
    display("now delete area "..name)
    deleteArea(id)
  end
end

no more function needed~
