CI
Docker images
registry.gitlab.com/kaitaistructcompile.py/kaitai_struct_python_docker:latest- an image with CPython, GraalVM, GraalPython, KSC, python runtime,kaitaiStructCompile.py, and its CLI backend. Unstable versions of the software are used. Currently Debian-based, but sometimes this will be migrated to Alpine.blacktop/kaitailibrespace/kaitaiβ docker image of the kaitaistruct-compiler used in the Libre Space Foundation Databasedavefr/kaitai-kscβ Kaitai Struct compiler in a container (Repository)
