Comments Density Analyzer

The Comments Density Analyzer is a tool to help you monitor and manage comments in your codebase.

Why Use It?

• Control TODOs and FIXMEs in CI/CD: Ensure these comments are not proliferating unchecked in your codebase.
• Spot Problematic Comments: Identify regular comments explaining "shitty code" or remnants of commented-out code.
• Enforce Documentation Standards: Require docblocks for classes and methods to maintain clear, consistent documentation.

All of this is made possible with a powerful plugin system (see the documentation for examples).

Features

• Multiple Comment Types: Detect and analyze regular comments, docblocks, TODOs, FIXMEs, and license headers.
• Plugin Support: Extend functionality by creating custom plugins via a simple interface.
• Detailed Reporting: Quickly identify areas of your code that need attention.
• Thresholds and Exit Codes: Set thresholds for comment types and return an exit code when they are exceeded.
• Configurable Reports: Output results to the console or as an HTML report.
• Baseline Support: Filter out known technical debt using a baseline file and focus on new issues.

Configuration

During installation, the tool can generate a default configuration file. Customize your analysis by editing the comments_density.php file:

<?php

declare(strict_types=1);

use SavinMikhail\CommentsDensity\AnalyzeComments\Comments\FixMeComment;
use SavinMikhail\CommentsDensity\AnalyzeComments\Comments\RegularComment;
use SavinMikhail\CommentsDensity\AnalyzeComments\Comments\TodoComment;
use SavinMikhail\CommentsDensity\AnalyzeComments\Config\DTO\Config;

return new Config(
    directories: [
        'src',
    ],
    thresholds: [
        RegularComment::NAME => 0,
        TodoComment::NAME => 0,
        FixMeComment::NAME => 0,
    ],
);
