DreamMaker Language Client

This VS Code extension acts as a client to the DreamMaker language server, a component of SpacemanDMM. It provides language-related services for DreamMaker, the scripting language of the BYOND engine. It is currently best used in tandem with the BYOND DM Language Support extension, which provides syntax highlighting.

The extension has an optional auto-update feature for the language server, with binaries available for Windows and Linux. On other platforms, the path to the dm-langserver binary may be specified manually.

Language server features include:

  • Workspace symbol search (Ctrl+T).
  • Go to definition (Ctrl+Click).
  • Go to type definition.
  • As-you-type autocomplete.
  • Signature help in proc calls.
  • Find references to a symbol.
  • Current file outline view.
  • Hovering var and proc definitions to see their parents.
  • And more, with details at the language server documentation.

Additional extension features include:

  • Project object tree view.
  • Build task (Ctrl+Shift+B) support for invoking DreamMaker.
  • Status bar control to toggle a file's tickmark in the .dme.
    • Optionally automatically ticking created/unticking deleted files.
  • Built-in DM Reference browser.
    • Open index with "DreamMaker: Open DM Reference" in the command palette.
    • Look up items with workspace symbol search, go to definition, or object tree.
