Perl Exception Handling Guide

The main methods for handling exceptions and errors in Perl include:

  1. Capture exceptions using eval block.
eval {
    # 代码块可能会抛出异常的地方
};
if ($@) {
    # 处理异常的代码
    print "Caught exception: $@\n";
}
  1. Throw an exception using the die function.
die "An error occurred";
  1. Utilize the Carp module to display detailed error messages.
use Carp;
croak "An error occurred";
  1. Catch exceptions using the Try::Tiny module.
use Try::Tiny;
try {
    # 可能会抛出异常的代码块
} catch {
    # 处理异常的代码

};
