NAME

criticism - Perl pragma to enforce coding standards and best-practices

SYNOPSIS

  use criticism;

  use criticism 'gentle';
  use criticism 'stern';
  use criticism 'harsh';
  use criticism 'cruel';
  use criticism 'brutal';

DESCRIPTION

This pragma enforces coding standards and promotes best-practices by running your file through Perl::Critic before every execution. In a production system, this usually isn't feasible because it adds a lot of overhead at start-up. If you have a separate development environment, you can effectively bypass the criticism pragma by not installing Perl::Critic in the production environment. If Perl::Critic can't be loaded, then criticism just fails silently.

Alternatively, the perlcritic command-line (which is distributed with Perl::Critic) can be used to analyze your files on-demand and has some additional configuration features. And Test::Perl::Critic provides a nice interface for analyzing files during the build process.

CONFIGURATION

The import argument is a named equivalent to the numeric severity levels in Perl::Critic. For example, use criticism 'gentle'; reports only the most dangerous violations. On the other hand, use criticism 'brutal'; reports every violation. If the import argument is not defined, it defaults to 'gentle'.

The criticism pragma will obey whatever configurations you have set in your .perlcriticrc file. See "CONFIGURATION" in Perl::Critic for more details.

DIAGNOSTICS

Usually, the criticism pragma fails silently. But if you set the DEBUG environment variable to a true value or run your program under the Perl debugger, you will get a warning when criticism fails to load Perl::Critic.

NOTES

The criticism pragma applies to the entire file, so it is not affected by scope or package boundaries and use-ing it multiple times will just cause it to repeatedly process the same file. There isn't a reciprocal no criticism pragma. However, Perl::Critic does support a pseudo-pragma that directs it to overlook certain lines or blocks of code. See "BENDING THE RULES" in Perl::Critic for more details.
