Perl bareword file handle opened at line

It works, but usually it is a lot more readable if every package is in its own file. In both cases I already had use strict; and use warnings; in the package. That's what I did in the earlier , but I still had to add 1; at the end of the files to let it return true. After each such step, before committing the changes I've ran the tests and after committing the changes and pushing them out to GitHub, it has also triggered Travis-CI to build and test the code.

This, along with the decent test coverage provides me the necessary confidence to make bold changes and move forward. So I've release version 1. Toggle navigation Perl Maven. Useless use of hash element in void context Useless use of private variable in void context readline on closed filehandle in Perl Possible precedence issue with control flow operator Scalar value Formatted printing in Perl using printf and sprintf.

Severity: 4 Module does not end with "1;" at line 2, column 1. Must end with a recognizable true value. Severity: 4 Code before warnings are enabled at line 2, column 1. Severity: 4 Out of these 4 violations two relate to the fact that we write a script and not a module. We don't really want to care about those and so we would like to turn those off.

There are a number of ways to do that, one of them is to provide the names of the rules on the command line with the --exclude flag. In order to find out the names we need to exclude we can run perlcritic --stern --verbose 8 examples.

Severity: 4 [InputOutput::RequireBriefOpen] Close filehandles as soon as possible after opening them at line 2, column 1. Code before warnings are enabled tells us to add use warnings; at the beginning of the code just as it is explained in the article that asks you to always use warnings More levels of perlcritic The perlcritic command line tool actually has 5 levels of severity.

So far we tried level 5 and 4 corresponding to the words "gentle" and "stern". The other 3 levels are "harsh", "cruel", and "brutal" creating a growing level of pain. After reading lots of different web pages and trying various weird variants, I finally figured out that the problem was the comma.

Remove the comma and it works. Save my name, email, and website in this browser for the next time I comment. Notify me of followup comments via e-mail. Previous post: How to Backup Linux?
