Misc functions for Lua

randomfuncs.lua

-- a bunch of random functions for Lua

-- allows a string to explore a table
-- you pass it the string and the table you allow it to explore
-- it formats the string like "You have {points} points!" (equivalent to "You have " .. t.points .. " points!")
-- it also can explore tables inside the table, like "Hi {player.name}!"
-- or a numerical index "Hi {0}" "Hi {player.0}"
local function format(str, t)
    return string.gsub(str, "{(.+)}", function(s)
        local value = t
        for k in string.gmatch(s, "([^%.]+)") do
            value = value[tonumber(k) or k]
        end
        return tostring(value)
    end)
