p={} --this is an empty table; all of our modules will probably start with this
--in a sense, p is table that holds all the names of the functions
--p is the conventional variable for this

function p.Namma(frame) --function is a datatype in Lua; when we're calling things from outside the module, use frame
    return "Dearvva máilbmi!"
end --end marks the end of a block in Lua

p.Hi = function(frame) -- this is the same as function p.Hi(frame). Some people prefer one way over the other
    strName = frame.args.name or "Jimbo"
    --str* is just a hint that a string is expected. args is the list of parameters you passed to that function
    --boolean ops => lowercase
    --if first part is not true, read second part
    return "Dearvva Luas mu ustibiidda! " .. strName .. ".<br>" --don't forget to use the same name for the var here; double dot is the concat operator
end

--task3
function p.temp(frame)
    cel = tonumber(frame.args.celsius) or 0 --this is a string; if tonumber can't convert str into number, it returns nil, not the orig value, so it will fail.
    fah = cel*9/5+32 --here it's not
          --this will autocache it into a floating point
    if cel > 10 then --this is a test
         msg = " ja dat lea liekkas!" --note: space
    else 
         msg = " ja dat ii gal leat liekkas!"
    end --this is the end of the test
    return "Temperatuvra fahrenheitis lea " .. fah .. msg .. "<br>"

--table is Lua's only complex data type; everything is made out of them in Lua
--indices in Lua can be any datatype
