Codebase metrics

A measured snapshot of the Domain Path codebase and its submodules, counted with cloc. Charts show code lines (blank and comment lines excluded) unless stated otherwise.

Snapshot

Measured on the 3.x branch, 2026-07-02. 98 files, 5,827 lines of code, 2,635 comment lines, 1,386 blank (9,848 lines in total). See Methodology to reproduce.

At a glance

Code	Comment	Blank	Files	Production	Test
5,827	2,635	1,386	98	2,974	2,853

Production vs test

Domain Path ships 2,853 lines of test code backing 2,974 lines of production code, a 96% test-to-production ratio.

Lines by language

Language	Code	Comment	Blank	Files
PHP	4,807	2,570	1,198	74
Markdown	464	0	181	6
YAML	261	65	7	13
CSS	258	0	0	1
Text	18	0	0	2
JSON	16	0	0	1
SVG	3	0	0	1

Composition

Across all languages, code is 59% of the lines, comments 27%, and blank lines 14%. The comment share reflects Drupal's docblock conventions.

By submodule

Production (brass) and test (steel) code per submodule, largest first.

Submodule	Production	Test	Total
domain path (core)	2,343	1,980	4,323
domain_path_pathauto	631	873	1,504

Test suite

Domain Path ships 34 automated test classes (93 test methods), counted by type below.

Test type	Classes	Methods
Kernel	15	67
Functional	17	21
FunctionalJavascript	2	5
Total	34	93

Architecture surface

What the module contains, counted across Domain Path and its submodules: the Drupal building blocks (services, plugins, hooks, routes, entities) that make up its public and internal API.

Element	Count
Services	16
Event subscribers	0
Hook implementations	10
Routes	1
Permissions	1
Forms	2
Controllers	0
Content entity types	0
Config entity types	0
Config schema types	1
Plugins	11

Plugins break down by type as follows, largest first:

Methodology

Counts are produced with cloc from the module root, excluding node_modules:

cloc --exclude-dir=node_modules .

Production and test totals split on the test directory:

# production
cloc --exclude-dir=node_modules --not-match-d='(^|/)tests(/|$)' .
# test
cloc --exclude-dir=node_modules --match-d='(^|/)tests(/|$)' .

Test classes are counted by their directory under tests/src (Unit, Kernel, Functional, FunctionalJavascript); the method column counts test-prefixed methods plus those annotated @test or #[Test]. The architecture surface counts service definitions in *.services.yml, route and permission keys in *.routing.yml and *.permissions.yml, #[Hook] attributes, plugin classes under src/Plugin/, forms and controllers under src/Form and src/Controller, entity-type attributes in src/Entity, and top-level types in config/schema/*.yml, all summed across the module and its submodules.

The charts are static inline SVG generated from the JSON that cloc emits, so they need no JavaScript or charting plugin. This page is refreshed periodically.
