Re: Error handling - how much/where/how?

in reply to Error handling - how much/where/how?

It's an option to use a common use error handling library. As sometimes giving the error on the return of the sub is not a good option (for example a sub that can return any value).

I use the Error library. It implements the try/catch syntax, enables printing the stack trace (as someone suggested on this thread) and doesn't require other things from people who use your module, since the exception is a regular die (with some info saved inside Error).

I like this approuch because it's easier to handle errors from methods that can throw many types of exceptions, you can programatically do something when *this* error and otherthing when *that* error very easy.

You might want to be careful using Error. There can be some unexpected negative side-effects. Perrin's write up Re: Re2: Learning how to use the Error module by example has the details. (I've written Exception::Class::TryCatch to bring some try/catch sugar to the Exception::Class module, and you might consider that in place of Error.)

Yeah, actually I had segfaults with Error prior to 0.15, but I'll consider switching to any other module, as Error is kindly to generate weird behaviour when you do something wrong... I just didn't know any good one...
