exception

How do I get ruby to print a full backtrace instead of a truncated one?

When I get exceptions, it is often from deep within the call stack. When this happens, more often than not, the actual offending line of code is hidden from me: tmp.rb:7:in `t’: undefined method `bar’ for nil:NilClass (NoMethodError) from tmp.rb:10:in `s’ from tmp.rb:13:in `r’ from tmp.rb:16:in `q’ from tmp.rb:19:in `p’ from tmp.rb:22:in `o’ from tmp.rb:25:in … Read more

Proper use of errors

by

I’m using TypeScript for a reasonably large project, and am wondering what the standard is for the use of Errors. For example, say I hand an index out of bounds exception in Java: throw new IndexOutOfBoundsException(); Would the equivalent statement in TypeScript be: throw new Error(“Index Out of Bounds”); What other ways could I accomplish … Read more

How to handle AccessViolationException

The odd thing is that I have wrapped my call in a try catch, which has handlers for AccessViolationException, COMException and everything else, but when Visual Studio (2010) intercepts … Read more

Why not use exceptions as regular flow of control?

To avoid all standard-answers I could have Googled on, I will provide an example you all can attack at will. C# and Java (and too many others) have with plenty of types some of ‘overflow’ behaviour I don’t like at all (e.g type.MaxValue + type.SmallestValue == type.MinValue for example : int.MaxValue + 1 == int.MinValue). … Read more
