[Unity]console中定位lua文件并在sublime中打开

在雨松MOMO的微博上发现可以传入lua文件路径和行数，在sublime中直接定位

由于最近一直在写lua， 也苦于开发工具的匮乏，所以就捣鼓了一下： 下面可以看到lua代码输出的内容，双击这一条log，就根据我的配置打开sublime跳转到对应的文件以及行：

使用方法：将下面的C#代码放到工程Editor目录下面，然后在菜单栏Tools下面有两个按钮，分别配置sublime可执行文件的路径和lua工程的根目录。

另外需要注意的是，lua层的输出有格式规范，从上面的示例图片中可以考到，lua文件的相对路径信息在和中间，行号也在和之间。在lua层我是这么做的： 在lua执行的最开始，加入这么一段代码以替换全局的print函数，然后由外部调用该函数，会得到调用处的文件信息和行号，输出到console中，之后就会根据这些信息来定位到相应的lua文件和行。

local tempPrint = print function print(...) local tempLog = "" for _, singleLog in ipairs({...}) do tempLog = tempLog..singleLog end tempPrint(tempLog, "<filePath>", debug.getinfo(2).short_src ,"</filePath><line>" ,debug.getinfo(2).currentline ,"</line>") end

下面是C#代码：
