Don't miss the next issue!

Hello there!

as you can surely tell, there have been some changes in the Perl Weekly. First of all let me welcome Neil Bowers, the newest addition to the Perl Weekly editors. I am sure it will be a lot of fun for him and for you, the reader who will see different styles of editing. This time in British English. I hope my spell-checker won't 'fix' his words.

In order to make it easier to distinguish who is the editor, the From address is now set to the current editor, and you will also see a small avatars of the person to the right of this text. Somewhere there =>

In addition we started to include little avatars of the authors. I hope this will make the whole newsletter more personal. We can't always find a real picture of the person, but we'll try. If you see an article without an image, and you can help finding one (80x80), please send it to us.

Lastly, for today, if you would like to submit an article or want to send a comment to all the editors, please send it to the new address.

Managing Boilerplate with Import::Base Tweet Facebook Google+
by Doug Bell (PREACTION)

Copy-pasting code snippets is very unpleasant. The Modern::Perl module addresses this issue, but introduces some other possible problems. Import::Base makes it easy to create modules similar to Modern::Perl that will import a number of other modules to fit your preferences. This might not be a good idea in a publicly released module, but it might be useful in a closed environment, such as an in-house project of a company where you supposed to have better control over the code anyway.

Reporting mismatched delimiters Tweet Facebook Google+
by Jeffrey Kegler (JKEGL)

You probably have already encountered the case when Perl reports a syntax error and provides a friendly suggestion: 'Might be a runaway multi-line "" string starting on line 5'. Apparently, in the general case it is quite hard to notice when delimiters don't match up. Jeffrey Kegler explains how this can be done using Marpa.

StackOverflow - Number of Perl questions by month Tweet Facebook Google+
by Miguel Prz (NICEPERL)

Miguel Prz (niceperl) (the guy who has the weekly report about Perl on StackOverflow), created a graph showing the number of Perl-related questions. (It would be even more interesting to see that compared to the number of Python/PHP etc. related questions, and the total number of questions.) From this graph it seems that the summer of 2013 was the peak for Perl. On Stack Overflow.
