NAME

Try - nicer exception handling syntax

VERSION

version 0.03

SYNOPSIS

    try {
        die "foo";
    }
    catch {
        when (/foo/) {
            warn "Caught foo";
        }
    }

DESCRIPTION

This module implements a try/catch/finally statement. It is based heavily on (and mostly implemented via) Try::Tiny. The differences are:

  • It is a statement. my $foo = try { ... } doesn't work anymore, but in return, you don't have to remember the trailing semicolon anymore. eval still works fine if you need an expression (in 5.14+ at least).

  • The blocks are ordered, and only one catch and finally block are supported. try { } finally { } catch { } and try { } catch { } finally { } finally { } do not work with this module, mostly because that's just extra complexity for no real purpose.

  • catch and finally are no longer exported - they are just part of the syntax of the try statement. This is almost certainly not an issue.

EXPORTS

try

try takes a block to run, and catch exceptions from. The block can optionally be followed by catch and another block and finally and another block. The catch block is run when the try block throws an exception, and the exception thrown will be in both $_ and @_. The finally block will be run after the try and catch blocks regardless of what happens, even if the catch block rethrows the exception. The exception thrown will be in @_ but not $_ (this may change in the future, since I'm pretty sure the reasoning for this is no longer useful in 5.14).
