1 对于项目中一些比较长的日志，比如前后端交互协议具体数据等，这些日志内容可能会比较长，在unity控制面板上查看不是十分方便，我们可以对双击事件进行扩展，将日志保存到一个文本中，然后用系统默认的文本查看工具查看这个日志
2 项目中如果用到了lua，当我们在控制台输出lua文件的时候，能不能双击日志用我们的代码编辑器软件打开日志输出位置

console日志双击然后用记事本打开显示

我们先用 OnOpenAsset 特性，重写双击回调方法，这个方法返回false，会继续执行系统默认日志双击打开方法，返回true则会中断。
我们想要的效果是用记事本打开这个特殊日志，但是不需要跳转到对应的代码输出位置
首先我们先在lua里面把日志输出方法重写一下，在日志输出的时候，添加一个标签 “”,当我们检测到双击的日志信息包含这个标签，则用记事本打开这一段日志（我们也可以把一些特殊的日志先在代码中缓存，在这个时候调用缓存读取那些特殊的日志进行输出显示）

function printLongLog(fmt, ...)local logText = string.format(fmt, ...)local debugInfo = debug.getinfo(2)local str = string.format("%s\n<open in file>", logText, debugInfo.short_src, debugInfo.currentline)local logMessage = concatStrs(str, debug.traceback("", 2))UnityEngine.Debug.Log(logMessage)
end

然后再C#代码中监听这一段日志

 [OnOpenAsset(0)]public static bool OnAsset(int instanceID, int line){string assetPath = AssetDatabase.GetAssetPath(instanceID);string fileExtension = Path.GetExtension(assetPath);string stackTrace = GetStackTrace();if (string.IsNullOrEmpty(stackTrace)){return false;}if (stackTrace.Contains("<open in file>")) //对于一些比较长的日志，添加标签<open in file>，双击的时候再文本中打开{openLog(stackTrace);return true;}return false;}

获取console里面的日志

private static string GetStackTrace(){var consoleWindowType = typeof(EditorWindow).Assembly.GetType("UnityEditor.ConsoleWindow");var fieldInfo = consoleWindowType.GetField("ms_ConsoleWindow", BindingFlags.Static | BindingFlags.NonPublic);var consoleWindowInstance = fieldInfo.GetValue(null);if (null != consoleWindowInstance && (object)EditorWindow.focusedWindow == consoleWindowInstance){fieldInfo = consoleWindowType.GetField("m_ActiveText", BindingFlags.Instance | BindingFlags.NonPublic);string activeText = fieldInfo.GetValue(consoleWindowInstance).ToString();return activeText;}return "";}

用记事本打开日志文件，我们先把日志信息保存在本地，然后调用系统方法打开这个文件
这里用到了一个方法 System.Diagnostics.Process.Start(fileName),参数是文件的完整路径，调用系统默认方式打开改文件

private static void openLog(string stackTrace){string fileName = GetFileSaveName();string saveDirPath = Application.dataPath + "/../Debug";if (!Directory.Exists(saveDirPath)){Directory.CreateDirectory(saveDirPath);}string savePath = saveDirPath + "/" + fileName;File.WriteAllText(savePath, stackTrace);System.Diagnostics.Process.Start(savePath);}private static string GetFileSaveName(){DateTime currentTime = DateTime.Now;string customFormat = currentTime.ToString("yyyy_MM_dd_HH_mm_ss");string fileName = $"debug_{customFormat}.txt";return fileName;}

双击打开lua日志然后用lua编辑器定位到日志输出位置

对于lua输出的日志，我们为了便于打开可以用类似上面的方法重新封装一个lua日志输出方法，然后通关特殊标签的进行确定lua文件的名称和对应的行号。也可以进行拆分lua堆栈数据取到lua代码名称和对应堆栈。
添加标签方式的lua日志输出

function print(fmt, ...)local logText = string.format(fmt, ...)local debugInfo = debug.getinfo(2)local str = string.format("%s\n<filePath>%s</filePath><line>%s</line>", logText, debugInfo.short_src, debugInfo.currentline)local logMessage = concatStrs(str, debug.traceback("", 2))UnityEngine.Debug.Log(logMessage)
end

获取文件名称和行号

static bool OpenLua(string logText){//获取lua文件路径Regex regex = new Regex(@"<filePath>.*<\/filePath>");Match match = regex.Match(logText);if (!match.Success){return false;}string filePath = match.Groups[0].Value.Trim();int length = filePath.Length - 10 - 11; //去掉开头和结尾的字符串 <filePath>  </filePath>filePath = filePath.Substring(10, length);filePath = filePath.Replace(".", "/");if (!filePath.EndsWith(".lua")){filePath = filePath + ".lua";}//获取日志行号Regex lineRegex = new Regex(@"<line>.*<\/line>");match = lineRegex.Match(logText);if (!match.Success){return false;}string luaLineString = match.Groups[0].Value;luaLineString.Trim();length = luaLineString.Length - 6 - 7;luaLineString = luaLineString.Substring(6, length);int luaLine = int.Parse(luaLineString.Trim());return OpenFileAtLineExternal(filePath, luaLine);}

对于系统默认输出日志，我们通关拆分字符串方式获取

 static bool OpenLuaDefault(string logText){int index = logText.IndexOf("stack traceback:");string temp = logText.Substring(index, logText.Length - index);string[] arr = temp.Split(':');if (arr.Length < 3){return false;}string filePath = arr[1].Trim();int luaLine = int.Parse(arr[2]);filePath = filePath + ".lua";return OpenFileAtLineExternal(filePath, luaLine);}

有了文件名和行号，我们就可以通关调用VScode或者Idea编辑器软件，打开对应的文件并定位到指定的行

static void OpenFileWith(string fileName, int line){string editorPath = EditorUserSettings.GetConfigValue(EXTERNAL_EDITOR_PATH_KEY);System.Diagnostics.Process proc = new System.Diagnostics.Process();proc.StartInfo.FileName = editorPath;string projectRootPath = EditorUserSettings.GetConfigValue(LUA_PROJECT_ROOT_FOLDER_PATH_KEY);if (string.IsNullOrEmpty(projectRootPath)){SetLuaProjectRoot();return;}string procArgument = "";if (editorPath.IndexOf("idea") != -1) //idea{procArgument = string.Format("{0} --line {1} {2}", projectRootPath, line, fileName);}else if (editorPath.IndexOf("Code.exe") != -1) // VSCode{string filePath = Path.Combine(projectRootPath, fileName);procArgument = string.Format("-g {0}:{1}:0", filePath, line);}else{procArgument = string.Format("{0}:{1}:0", fileName, line);}proc.StartInfo.Arguments = procArgument;proc.Start(); }
