饥荒代码测试

local print_loggers = {}

local function print_1(...)
    print('1\n')
end

local function print_2(...)
    print('2\n')
end

local function print_3(...)
    print('3\n')
end

table.insert(print_loggers, print_1)
table.insert(print_loggers, print_2)
table.insert(print_loggers, print_3)


for i,v in ipairs(print_loggers) do
    v('1')
end

print_loggers[2]() 直接调用print_2 lua语言下标从1开始

无限递归了，不行

local print_loggers = {}

print('123')
function AddPrintLogger( fn )
    table.insert(print_loggers, fn)
end

local consolelog = function(...)
    print(...)
end

print = function(...)
    for i,v in ipairs(print_loggers) do
        v(str)
    end
end

AddPrintLogger(consolelog)

print('213')
