Cool Tools: Vim Tricks

This post will help me remember cool tricks I learn in VIM.  It's mostly for me to find things I've forgotten how to do ...

 Select an XML/HTML tag block

 
Tag blocks      *tag-blocks*

For the "it" and "at" text objects an attempt is done to select blocks between
matching tags for HTML and XML.  But since these are not completely compatible
there are a few restrictions.

The normal method is to select a  until the matching .  For "at"
the tags are included, for "it" they are excluded.  But when "it" is repeated
the tags will be included (otherwise nothing would change).  Also, "it" used
on a tag block with no contents will select the leading tag.

Finding CLR exceptions without visual studio





















(If you want to understand what exception code 0xe0434352 is, read this post )   Often exceptions are thrown and caught and you don't see them. You probably know how to debug this in Visual Studio, so let me show you how to do it in cdb.  Sample Code:    class Program {  static void Main(string[] args)  {      foreach (var x in Enumerable.Range(0,2000))      {          Thread.Sleep(TimeSpan.FromSeconds(1));          Console.WriteLine("Hello World");          ThrowAndCatchException();      }   }   private static void ThrowAndCatchException()  {      try      {         throw new NotImplementedException();      }      catch(Exception)      {      }  } } Output of the application:  Hello World Hello World Hello World Nothing about an exception, but you're sure it's happening behind the covers -- fire up cdb:  C:\Program Files\Debugging Tools for Windows (x64)>cdb -pn consoleapplication3.exe  <SNIP>  ModLoad: 000007fe`f7e90000 000007fe`f7eb4000   C:\Windows\Mi...

Why do I keep getting exception code e0434352?





















If you want to know how to debug CLR exceptions using cdb then read this post .   Exception code e0434352 is the exception code used internally by the CLR to represent most exceptions(*).    Regardless  of if you throw a System.NullReferenceException or a  System.ArgumentException in C#, you'll throw a SEH exception e0434352  under the covers.   A fun way to validate this theory is  to watch what happens to the CLR exceptions settings in cdb. Fire up  cdb, and see the state of clr exceptions:   0:000> .shell -ci "sx" findstr clr  clr - CLR exception - second-chance break - not handled clrn - CLR notification exception - break - handled .shell: Process exited  Now, set the exception handler for exception number e0434352 and recheck the value of the clr exception handler:  0:000> sxe e0434352 0:000> .shell -ci "sx" findstr clr  clr - CLR exception - break - not handled clrn - CLR notification exception - break - handled .shell: Process exited  Armed with ...
