【入门夯实】Lua gsub双返回值：红名洗白播报的替换计数

local function report(actor, name)
    -- 末位展开：次数被当成第4个参数塞进消息
    sendmsg(actor, 1, "洗白结果", string.gsub(name, "红名", "侠士"))
end

local function report(actor, name)
    local fixed, times = string.gsub(name, "红名", "侠士")
    sendmsg(actor, 1, name .. " 洗白 " .. times
        .. " 处 → " .. fixed)
end
report(actor, "红名刀客红名装")   -- 2处替换，计数直接可用
