Reverse string

[abel8909]

hi everyone and happy christmas eve, i'm new to this lua, could someone help me how to reverse string example
FACTION_STANDING_INCREASED = "%s %d"
for
FACTION_STANDING_INCREASED = "%d %s"

I found this code but it doesn't work

ChatFrame_AddMessageEventFilter("CHAT_MSG_COMBAT_FACTION_CHANGE", function(frame, event, message, ...) local which, faction, amount = strmatch(message, "^[%+%-] (%+) (%d+) rep$") if which and faction and amount then return false, (format("%s%d %s rep", which, amount, faction)), ... end end)
