The osc-language-server is a component that enables text editors to do live error checking of an OpenSCENARIO DSL file while editing it. This includes both errors in the usage of the language itself as well as the domain model. Further, it provides information about elements like types, methods, and many more. This ensures that the files are compliant with the ASAM standard.
The osc-language-server can be downloaded for free as an extension for Microsoft Visual Studio Code from its integrated market place.
