The main difference is that it's a source filter module. As a source filter it can implement the same convenient interface without those nasty memory leaks and implicit anonymous subroutines (which can trick you, if you're not careful). Also after source parsing it converts the code into "native" perl code, so it's probably a little faster than Error.pm's approach. And, well. As far as I can tell, Error::TryCatch accomplishes its duty nicely. FUNCTIONS The interface is pretty straight-forward. I think that reading the synopsis is enough documentation. If you *really* need an explanation about how exception handling blocks work, you should take a look at Error.pm documentation. The only clause which I chose not to implement was the 'except' clause, since I consider it rather "exotic" and pretty much useless (at least for my purposes). And it would be a pain to implement. Unlike Error.pm, with Error::TryCatch you can return() from anywhere, but see CAVEATS below. EXCEPTION CLASSES Error::TryCatch was built with exception classes in mind and will even wrap anything it catches that is not a reference into a default unhandled exception class, whic

(active perl 5.12 installed on system) and I am getting the error Can't locate Error.pm in @INC (@INC contains: C:/Perl64/site/lib C:/Perl64/lib ) I manually searched and found Error.pm in C:/Perl64/lib/CPANPLUS.

See stackoverflow.com/questions/65865/… –daxim Jul 22 '10 at 7:55 This worked for me. Thanks daxim. –chuck taylor Jul 22 '10 at 13:46 add a comment| 4 Answers 4 active oldest votes up vote 3 down vote You have to install the module Error that can be found on CPAN. But be aware of this warning: Using the "Error" module is no longer recommended due to the black-magical nature of its syntactic sugar, which often tends to break. Its maintainers have stopped actively writing code that uses it, and discourage people from doing so. See the "SEE ALSO" section below for better recommendations. share|improve this answer edited Jul 22 '10 at 9:01 daxim 33.9k44198 answered Jul 22 '10 at 8:06 Toto 47.1k163981 Why the downvotes ? –Toto Jul 22 '10 at 13:02 1 To do this, run sudo cpan Error –Alastair Irvine Nov 20 '13 at 4:08 add a comment| up vote 1 down vote lib/CPANPLUS/Error.pm is a core "CPANPLUS::Error" modul

Install CPAN Modules using the package management system Install CPAN modules into your local Perl library using CPAN Setting up a private CPAN library - without admin privileges Using your private CPAN repository in TWiki Installing CPAN modules error.pm perl download manually ActiveState Perl MiniCPAN External Links Introduction CPAN (Comprehensive Perl Archive Network) is a large repository of Perl modules. Standard Perl already has many CPAN libraries installed from birth. The TWiki package contains most required non-standard CPAN modules. Usually you have to install a few extra CPAN modules to use all the features in TWiki. If you install additional plugins you might need to install additional CPAN modules. This guide tells you how to do that. For building the CPAN modules from sources it is assumed that you have a fully working Perl and C development environment (including a C compiler and make tool) - but you may have much easier alternatives. This is not required if you can install the libraries as packages. What Do I Need? These are the CPAN modules that you are recommended to install CGI::Session - Needed for TWiki's session feature which is really a must have Error - Needed if you later want to develop plugins.
