git submodule init # once
git submodule update --recursive # upgrading (after a `git pull`)

composer install

For more dev-tools you may install phpstan/phpstan composer require -dev phpstan/phpstan which shows a lot of stucture problems of the application and it should getting more attention (beginning with level=1).

Update existing code

git pull
git submodule update
composer install

Running tests

VERSION 4:
Improved additions for CI systems (e.g: jenkins) where `phing` is the
prefered build tool. `composer` the prefered package manager.

# shows you the options
./phing -l

# executes the tests
./phing test

# executes the tests and create the code coverage
./phing coverage

# run all tasks (CS checks, coverage, tests, sca...)
./phing all

...

cd tests
sh ./runTests.sh

# have a look at ../docs/CodeCoverage (use a browser after execution)
sh ./runTestsCoverageCreate.sh

# playground:
php readerDemo.php | less
# or to update tmp file to check for changes:
php readerDemo.php > data/pspp.sav.printr.txt
