DreamMaker Language Server

This package is a language server implementation for DreamMaker, the scripting language of the BYOND game engine. All features are dependent on client support.

• Sublime Text 3 package (code).
• Other editors may have generic language client packages which will be compatible.

Code completion

• Completes names of typepaths, procs, type vars, local vars, and macros.

• Completes var and proc overrides in type definitions.
  • Proc overrides include a stub which calls ..().

Hover

• Shows inheritance information when hovering proc headers and type vars.

Go to definition

• Finds the definition of typepaths, procs, type vars, local vars, and macros.
• In some clients, integrates with DM Reference browser.

Workspace symbol search

• Searches macros, types, procs, and vars.
• Prefix query with # to search macros only, var/ to search vars only, or proc/ to search procs only.
• Include / in query to search types only.
• In some clients, integrates with DM Reference browser.

  • Typepaths as a literal.
  • Procs, called and overridden.
  • Type vars, read, written, and overridden.

Diagnostics
