Hi all. Maybe some remember that I am working on installing and using xraylarch using fink, a package manager for macOS similar to MacPorts or Homebrew. Today I am happy to announce a major breakthrough: The first successful start of larch_gui. If anyone is interested in following the progress or even contributing, this is the my github branch of the fink/fink-distribution: https://github.com/fink/fink-distributions/tree/kamischi-xraylarch-new The next steps will be: - create macOS app-bundles within fink. - update the dependent python packages to recent versions. - add optional dependent python packages - enable and debug tests of xraylarch and dependent python packages - general debugging and staying up-to-date.
