Project status

Project structure

The src/ contains the PHP code and follows PSR-4 autoloading.

  • src/Map - Map display entry points (such as handling of #display_map) and their supporting code
  • src/ParserHooks - Entry points for all parser hooks except #display_map
  • src/Presentation - Presentation layer code that does not belong to a more specific directory
  • src/DataAccess - Persistence layer code that does not belong to a more specific directory
  • src/GeoJsonPages - Code that deals with pages in the GeoJson namespace
  • src/LegacyModel - Badly designed and deprecated representations of map elements (markers, polygons, etc)
  • src/LegacyMapEditor - Deprecated and Google Maps only Special:MapEditor page
  • src/SemanticMW - Semantic MediaWiki code except for the map entry point (which is in Map\SemanticFormat)
  • src/WikitextParsers - Parsers for the wikitext definitions of map elements (like the LegacyModel)

JavaScript, CSS and other web resources go into resources/.

Tests for PHP go into tests/ where they are grouped by test type (ie unit, integration). Within those test type directories the tests should mirror the directory structure in src/.

Running the tests

You can use the Makefile by running make commands in the Maps directory.

  • make ci: Run everything
  • make test: Run all tests and static analysis
  • make cs: Run all style checks

Alternatively, you can execute commands from the MediaWiki root directory:

  • PHPUnit: php tests/phpunit/phpunit.php -c extensions/Maps/
  • Style checks: vendor/bin/phpcs -p -s --standard=extensions/Maps/phpcs.xml
  • PHPStan: vendor/bin/phpstan analyse --configuration=extensions/Maps/phpstan.neon --memory-limit=2G
  • Psalm: php vendor/bin/psalm --config=extensions/Maps/psalm.xml

Beware that due to technical debt, some tests access the network.
