问题描述
=====================
经常需要在SharePoint的ULS日志中捞取一些带有callstack的信息, 而且需要把callstack展开细细查看. 然而, ULS log中的callstack是挤在一起的, 查看起来很不方便.
笔者原来一直手工添加换行符, 但是近期这类工作实在有点多, 于是开始想办法了.
问题举例, 笔者从ULS log中捞到这个CallStack,

研究
=====================
在Notepad++中新建一个文件, 随便输入几行文字
点击下面的选项
结果如下, 显然CR, LF是换行符.
使用CR, LF, Notepad++作为关键字, 经过搜索, 在Notepad++的官网上找到了如下的文字:
Ctrl+H with Extended option selected instead of Regexp. Search for "\r\n", or whatever your OS uses, and replace with what you need. It will replace the newline characters with what you entered. Note that Windows uses CR-LF newlines (\r\n), old Mac uses CR (\r) and Unix uses LF (\n). You can use View -> Show Symbol -> Show End Of Line to see which characters your file uses - files from other OSes may not behave as you expect because they have a different newline type.
Some examples: - To add a string to the end of all lines in Windows, in Ctrl+H with Extended mode enabled, replace \r\n with string\r\n - To add a string to the beginning of all lines in windows, in Ctrl+H with Extended mode enabled, replace \r\n with \r\nstring - To remove extra blank lines in windows, in Ctrl+H with Extended mode enabled, replace \r\n\r\n with \r\n - To remove all newlines, in Ctrl+H with Extended mode enabled, replace \r\n with nothing.
解决方案
=====================
使用Notepad++, 将内容贴入:
呼出替换对话框, 将<at>替换为<\r\nat>, 不包括尖括号.
结果如下:
就用这个技巧作为开端吧, 善用notepad++, 让工作效率疾驰如飞.
