为了让游戏前端数据输出更加条理，做了一个简单树状结构来打印数据。

ccmlog.lua

lua">local function __tostring(value, indent, vmap)local str = ''indent = indent or ''vmap = vmap or {}--递归结束条件if (type(value) ~= 'table') thenif (type(value) == 'string') then--字符串str = string.format("[[%s]]", value)else--整数str = tostring(value)endelseif type(vmap) == 'table' thenif vmap[value] then return '('..tostring(value)..')' endvmap[value] = trueendlocal auxTable = {}     --保存元表KEY(非整数)local iauxTable = {}    --保存元表valuelocal iiauxTable = {}   --保存数组(key为0)table.foreach(value, function(i, v)if type(i) == 'number' thenif i == 0 thentable.insert(iiauxTable, i)elsetable.insert(iauxTable, i)endelseif type(i) ~= 'table' thentable.insert(auxTable, i)endend)table.sort(iauxTable)str = str..'{\n'local separator = ""local entry = "\n"local barray = truelocal kk,vvtable.foreachi (iauxTable, function (i, k)if i == k and barray thenentry = __tostring(value[k], indent..'  \t', vmap)str = str..separator..indent..'  \t'..entryseparator = ", \n"elsebarray = falsetable.insert(iiauxTable, k)endend)table.sort(iiauxTable)table.foreachi (iiauxTable, function (i, fieldName)kk = tostring(fieldName)if type(fieldName) == "number" then kk = '['..kk.."]"end entry = kk ..

endccmlog = function(m,fmt,...)local args = {...}for k,arg in ipairs(args) doif type(arg) == 'table' or type(arg) == 'boolean' or type(arg) == 'function' or type(arg) == 'userdata' thenargs[k] = __tostring(arg)endendargs[#args+1] = "nil"args[#args+1] = "nil"args[#args+1] = "nil"local str = string.format("[%s]:"..fmt.." %s", m, unpack(args))print(str)local off = 1local p = CCLOGWARN if m == 'error' then p = CCLOGERROR elseif m == 'warn' then p = CCLOGWARNendwhile off <= #str do local subStr = string.sub(str, off, off+1024)off = off + #subStr--p(subStr)end
end--打印测试
reserved =  { [100] = { 300, 400}, 200, { 300, 500}, abc = "abc",[0] = {1,2,3,"abc"}}ccmlog("d","d",reserved)

打印效果如下：

lua">[d]:d {100} = {300, 400}, 200, {300, 500}, abc = "abc",[0] = {1,2,3,"abc"}
