category | The 'perlfunc' manpage eval EXPR eval BLOCK eval In the first form, often referred to as a "string eval", the return value of EXPR is parsed and executed as if it were a little Perl program. The value of the expression (which is itself determined within scalar context) is first parsed, and if there were no errors, executed as a block within the lexical context of perl error handling best practices the current Perl program. This means, that in particular, any outer lexical variables are visible to it, and any package variable settings or subroutine and format definitions remain afterwards. Note that the value is parsed every time the eval executes. If EXPR is omitted, evaluates $_ . This form is typically used to delay parsing and subsequent execution of the text of EXPR until run time. If the unicode_eval feature is enabled (which is the default under a use 5.16 or higher declaration), EXPR or $_ is treated as a string of characters, so use utf8 declarations have no effect, and source filters are forbidden. In the absence of the unicode_eval feature, will sometimes be treated as characters and sometimes as bytes, depending on the internal encoding, and source filters activated within the eval exhibit the erratic, but historical, behaviour of affecting some outer file scope that is still compiling. See also the evalbytes operator, which always treats its input as a byte stream and works properly with source filters, and the feature pragma. Problems can arise if the string expands a scalar containing a floating point number. That scalar can expand to letters, such as "NaN" or "Infinity" here for a quick overview of the site Help Center Detailed answers to any questions you might have Meta Discuss the workings and policies of this site About Us Learn http://stackoverflow.com/questions/10342875/how-to-properly-use-the-try-catch-in-perl-that-error-pm-provides more about Stack Overflow the company Business Learn more about hiring developers or posting ads with us Stack Overflow Questions Jobs Documentation Tags Users Badges Ask Question x Dismiss Join the Stack Overflow Community Stack Overflow is a community of 4.7 million programmers, just like you, helping each other.

But I am confused at how you can print the exception that returns. I would like to understand how to do the following try { // do something that will fail! } catch (Error e) { // Print out the exception perl error handling that occurred System.out.println(e.getMessage()); } How do I get the print of the error with the stack trace? perl error-handling try-catch share|improve this question edited Apr 27 '12 at 0:50 Sinan Ünür 93k13143284 asked Apr 26 '12 at 23:35 pitchblack408 6181618 add a comment| 3 Answers 3 active oldest votes up vote 34 down vote accepted You're probably better off using Try::Tiny which will help you avoid a number of pitfalls with older perls. use Try::Tiny; try { die "foo"; } catch { warn "caught error: $_"; }; share|improve this answer edited Apr 30 '12 at 20:24 LeoNerd 6,4771227 answered Apr 27 '12 at 0:53 Sinan Ünür 93k13143284 How would I dump this warning to the logs? –pitchblack408 Apr 29 '12 at 22:30 Can I create exceptions? –pitchblack408 May 8 '12 at 0:28 1 I am not sure what you're asking. You dump things in log files by logging them and you create exceptions by using die or croak. Are you asking how to put together exception objects etc? That would be a separate question. –Sinan Ünür May 8 '12 at 0:41 add a comment| up vote 29 down vote Last I checked, Error was deprecated. But here'
