Ryn for Visual Studio Code

Language support for Ryn and the Rynix library.

Features

• Syntax highlighting for keywords (fun, when, choose, extend, ...), primitive and built-in types, nested /* */ comments, #[...] attributes, string interpolation ("{player.health}"), 0x/0b literals, duration suffixes (250ms, 2s), and :: paths.
• Completion
  • after use and module::: std modules, project modules, and path dependencies from ryn.yaml (for example rynix::window);
  • after Type::: constructors, constants, and enum variants;
  • after value.: fields and methods of the inferred type. Types are inferred from x := Type::new(..), x: Type, x := y.method(..), field chains such as camera.eye., and self inside extend;
  • keywords, types, built-ins, and local names everywhere else.
• Signature help inside calls, hover with the declaration and its // comment, go to definition for project and dependency symbols, and an outline of functions, types, and extend blocks.
• Diagnostics: ryn check runs on the project when a .ryn file is opened or saved, and its errors appear in the editor and the Problems panel.
• Commands: Ryn: Run Project, Ryn: Build Project, Ryn: Check Current File, Ryn: Re-index Workspace; the run button in the editor title runs the project.
• Snippets: main, fun, struct, type, extend, when, choose, dropstruct, rynixwindow, and more.
