This tutorial explains about how to handle errors and exceptions in Perl Language.

Prior to Perl version 5.34, To hand handle exceptions, Third party libraries such as Try::Tiny used . Here is an example before

use Try::Tiny;

try {
        die "foo";
} catch {
        warn "error thrown: $_";
};

Perl version 5.34 introduced try,catch, finally syntax features

These are experimental feature, enabled by using below command.

use feature 'try'

Syntax:

try {
    // code
}
catch ($e) {
    warn "catch block; $e";
}
finally {
    print "finally block\n";
}

finally block is an optional.

if finally included, It executes the code inside it after code executed in try and catch blocks.

Notes:

  • finally block does not allow to use return, goto or loop controls.
