meson setup build
cd build && meson compile && meson install

A tests/docker-compose-yml file provides mhxd, hxtrackd, Janus, and Argus containers to test against. tests/run.sh will build and start all the containers. Note: The base Dockerfiles live in mishan/hotline-docker, and mishan/gtkhx-docker for the CI base image and SOCKS proxy.

./tests/run.sh
cd build & meson test

flatpak-builder --user --install --force-clean build-flatpak \
                com.nasledov.gtkhx.yml
flatpak run com.nasledov.gtkhx

The manifest pins org.gnome.Platform 49 and pulls the source from the working tree, so edits land in subsequent flatpak-builder runs without needing a fresh clone.
