### Problem to solve The language DM, for the BYOND game engine, has no syntax highlighting here as it does on GitHub. ### Intended users Users who write code in the BYOND DreamMaker language. ### Further details None ### Proposal Add the proper syntax highlighting for the language. ### Permissions and Security It is UI based. ### Documentation I'm not sure how to document a change like this. ### Testing It doesn't really pose any risks, even if the highlighting turns out bad; it's better than nothing. ### What does success look like, and how can we measure that? Success is when you can look at a DreamMaker .dm file in a GitLab repository, and the syntax is highlighted. ### Links / references
