Semantic MediaWiki extensions have all largely adopted the Gesinn IT Docker-based approach to development.
Once you've cloned a particular extension (e.g. SemanticResultFormats), then you want to execute a submodule update to pull in the build environment.
# change to the src directory
cd ~/src
# clone a SMW extension that you want to work on
git clone https://github.com/SemanticMediaWiki/SemanticResultFormats
# make sure you've got the latest code
git pull
# and create a branch to work on
git checkout -b 940-gallery-overlay-and-redirect-fix
# now we initialize the build system
git submodule update --init --remote
# note that if you've been working with docker-desktop, you may need to reset your docker context to 'default' from 'desktop-linux'
docker context ls
docker context use default
# Install the build system
make install
docker ps
# run some test
make ci
