Initially, Safe-DS was intended to be used from Eclipse, but we found the developer experience to be lacking. With the increasing popularity of LSP, we eventually removed Eclipse support and instead implemented an extension for VS Code. The LSP features of Xtext made this switch easy. But there are still several issues:
Desired solution
Langium seems to solve all those issues. The short-term roadmap also is very promising. It would also ease the implementation of a graphical language.
