Installation

Pdepend Summary Formatter tool requires PHP >= 7.4, latest version of PHP Depend and Composer.

composer require --dev pdepend/pdepend:"^2.15"
composer require --dev andrey-tech/pdepend-summary-formatter-php

Generate a default config file pdepend-summary-formatter.yml.dist in current working directory:

./vendor/bin/pdepend-summary-formatter --init

Then run PHP Depend to scan your source PHP-code in directory src and generate an XML report in file summary.xml:

./vendor/bin/pdepend --summary-xml=summary.xml --suffix=php src

Then run Pdepend Summary Formatter tool to show code quality metrics, measured by PHP Depend, in console and to write results to specified text file summary.txt:

./vendor/bin/pdepend-summary-formatter summary.xml --output-file=summary.txt

Command line options

./vendor/bin/pdepend-summary-formatter <path to pdepend file summary.xml>

The Pdepend Summary Formatter tool command line interface also accepts the following optional arguments:

• --init — Will generate a default config file pdepend-summary-formatter.yml.dist in current working directory.
• --output-file= — Write results also to the specified text file.
• --config-file= — The filepath to a custom config YAML file.
• --ignore-red-metrics-on-exit — Will exit with a zero code, even "red" metrics exist.
• --ignore-yellow-metrics-on-exit — Will exit with a zero code, even "yellow" metrics exist.
• --no-colors — Disable colors in console.

An example command line of Pdepend Summary Formatter tool and PHP Depend tool:

./vendor/bin/pdepend --summary-xml=./var/summary.xml --suffix=php src,tests
./vendor/bin/pdepend-summary-formatter ./var/summary.xml --config-file=./pdepend-summary-formatter.yml --output-file=./var/summary.txt

An example of output text file summary.txt:

Software metrics

PHP Depend (pdepend) tool can generate a large set of software metrics from a given code base. These values can be used to measure the quality of a software project and they help to identify that parts of an application where a refactoring should be applied.

Pdepend Summary Formatter tool shows only the part of software metrics, measured by PHP Depend, and shows them in green, yellow and red colors in the console, according to boundaries for values, defined in configuration YAML file.

This table shows a list of the software metrics by Pdepend Summary Formatter tool for entire project, classes, traits, methods. The table also shows the default values for "red" boundaries of software metrics, based on PHP Mess Detector (PHPMD) tool.

Note: ✓ — means there are no defined "red" color boundaries for this metric.

Configuration YAML file

By default Pdepend Summary Formatter tool is looking for following configuration YAML files is current working directory:

• pdepend-summary-formatter.yml,
• pdepend-summary-formatter.yml.dist.

Configuration YAML file allows to set color boundaries for values of software metrics.

Pdepend Summary Formatter tool currently defines three color boundaries:

A white value means there are no defined color boundaries for this metric.

You can also add/set custom colors and styles. See How to Color and Style the Console Output in Symfony console.
