We have removed the folders xdmcp, nx and st due to the fact that Gtk have deprecated the functions using the XEmbed protocol.
These folders have been split in a new repository as shown in the following example
# Split of the folder plugins/st in a new branch
git subtree split -P plugins/st -b plugins/st
# We add the remote of the new repository
git remote add plugins/st git@gitlab.com:Remmina/remmina-plugins.git
# We push to the new repository
git push plugins/st plugins/st
# We change to the location of the local copy of git@gitlab.com:Remmina/remmina-plugins.git
cd ../remmina-plugins/
# The branch plugins/st does not have the folder plugins, the st source is in the root
# The following subtree command recreate the folder structure (../Remmina is the main repo)
git subtree add -P plugins/st ../Remmina plugins/st
git push
The next step is to git rm -r plugins/st and if we need again st, it's enough to add it as a submodule:
git submodule add git@gitlab.com:Remmina/remmina-plugins.git plugins
The submodule part has to be tested as it'll cause issues with the existing files
