How to Create a PBP File with Multiple Tracks

Perl Best Practices (PBP) is a set of guidelines for writing high-quality, maintainable, and readable Perl code. The Perl::Critic engine is a tool that helps you identify awkward, hard-to-read, error-prone, or unconventional constructs in your code by enforcing these guidelines. In this article, we will explore how to create a PBP file with multiple tracks.

Before diving into the details, it's essential to understand what Perl::Critic is and how it works. Perl::Critic is an executable front-end to the Perl::Critic engine, which attempts to identify problematic constructs in your code. It's not limited to enforcing PBP and will even support rules that contradict Conway.

Creating a PBP file with multiple tracks requires some knowledge of Perl syntax and the Perl::Critic configuration options. Here are some basic usage examples to help you get started:

1. Report additional violations of Policies: You can use the `--policy` option to specify which policies you want to enforce. For example, to report additional violations of Policies that match m/variables/xms, you would run:

```

perlcritic --policy=m/variables/xms

```

2. Report top 20 most severe violations: To report only the top 20 most severe violations (severity >= 1), you would use the following command:

```

perlcritic --top-violations=20

```

3. Report only violations of things from 'Perl Best Practices': You can specify which rules to enforce by using the `--rules` option. For example, to report only violations of rules based on Perl Best Practices, you would run:

```

perlcritic --rules=PBP

```

4. Report all violations, regardless of severity: To report all violations, regardless of severity (severity >= 1), you would use the following command:

```

perlcritic --all-violations

```

5. Recursively process all Perl files beneath a directory: You can specify which files to analyze by using the `--directory` option. For example, to recursively process all Perl files beneath a directory called `mydir`, you would run:

```

perlcritic --directory=mydir

```

6. Report only most severe violations: To report only the most severe violation (severity = 5), you would use the following command:

```

perlcritic --most-severe-violation

```

These are just a few examples of how to create a PBP file with multiple tracks using Perl::Critic. For more information, including how to persistently configure this command so that you don't have to say so much on the command-line, see the documentation for Perl::Critic itself.

Remember, Perl::Critic is a powerful tool that can help you improve the quality of your code by identifying problematic constructs and enforcing best practices. By following these examples and experimenting with different configuration options, you can create a PBP file with multiple tracks that meets your specific needs.
