起因：做了个工具在console窗口罗列一些信息，基本结构是 [ 文件名        ：行号 ]，因为文件，行号长度不一，想要做到如下效果。

初步尝试，用以下方法：

string format = "{0,-10} {1,5}";  // -10 表示左对齐，10个字符宽；5 表示右对齐，5个字符宽
Debug.Log(string.Format(format, "File", "Line"));
Debug.Log(string.Format(format, "UI/Titan/UI_Titan_Main", "1"));
Debug.Log(string.Format(format, "Utils/GlobalFunction", "8"));

实际效果如下：

竟然没对齐？拷贝到IntelliJ 里查看

Utils/GlobalFunction                              |        :8
Lua/HookReloadLuaFuc                              |       :35
Lua/HookReloadLuaFuc                              |     :1290

IntelliJ用了等宽字符，所以看起来是对齐的。

后续就简单了，拿到console里字体的宽度就行了。

这里贴一个大概的实现，宽度表放在最后

一个简单的lua实现

local _QuickJumpTab = {"Utils/GlobalFunction:8","Lua/HookReloadLuaFuc:35:print_table","Lua/HookReloadLuaFuc:1290:print_table","UI/Titan/TitanUtil:10:泰坦相关Gid",
}local function GetFileLine(str)local strTab = split(str,":")return unpack(strTab)
end-- 判断是否是中文字符 并且返回字符长度
local function IsChineseChar(char)local byte = string.byte(char)if byte >= 0x80 thenreturn true,2elsereturn false,1end
endlocal function Utf8StringLen(str)local len = 0local strTab = StringToUtf8Table(str)for i, v in ipairs(strTab) doif IsChineseChar(v) thenlen = len + 12elselen = len + _ConsoleCharWidth[v] or 3 -- 3 is width of spaceendendreturn len
endlocal longestStr = ""
for k, v in pairs(_QuickJumpTab) dolocal fileStr = GetFileLine(v)if Utf8StringLen(fileStr) > Utf8StringLen(longestStr) thenlongestStr = fileStrend
end
local longestStrLen = Utf8StringLen(longestStr)
--logGreen("longestStrLen\t" .. longestStrLen)local _wrapColor = function(color,str)return concat({"<color=",color,">",str,"</color>"})
end-- 自己实现一个往左边或者右边加空格补齐长度的函数
-- 用于打印的时候对齐
local FillLen = function(str,len,align,fillStr)align = align or "left"local strLen = Utf8StringLen(str)if strLen >= len thenreturn strendlocal spaceLen = len - strLenlocal needFillCount = max(spaceLen,1)if not fillStr thenfillStr = " "needFillCount = needFillCount/_ConsoleCharWidth[fillStr]endlocal spaceStr = string.rep(fillStr,ceil(needFillCount))if align == "right" thenreturn concat({str,spaceStr})elsereturn concat({spaceStr,str})end
endlocal exSymbolLen = _ConsoleCharWidth[":"] + _ConsoleCharWidth["["] + _ConsoleCharWidth["]"]local _WrapDebugStr = function(file,line,des,fileColor,lineColor)fileColor = fileColor or "#CA550C"--"cyan"lineColor = lineColor or "#00FFFF"local maxFileLen = longestStrLen+8local fileStr = FillLen(file,maxFileLen,"right")local lineStr = FillLen(":" .. line,36,"left")fileStr = _wrapColor(fileColor,fileStr)lineStr = _wrapColor(lineColor,lineStr)local desFillStr = "-"local fillCharWidth = _ConsoleCharWidth[desFillStr]maxFileLen = maxFileLen + 36 + exSymbolLenif des thenlocal colorLen = Utf8StringLen("<color=white></color>")des = _wrapColor("white",des)des = FillLen(des,(maxFileLen+colorLen)/fillCharWidth,"right",desFillStr)elsedes = FillLen("",maxFileLen/fillCharWidth,"left",desFillStr)endstr = format("[%s%s]\n%s",fileStr,lineStr,des)return str
end
