What to do when the runtime you need isn't supported

Docs in progress. Some content or features may be missing or not covered in detail.

If the runtime you need — for example, Java, Kotlin, or Swift — is not supported, you can add it. The process involves implementing the runtime spec, registering the plugin, and wiring init and build support.

Adding a runtime requires implementing the spec in poly-bench-traits, registering the plugin, and wiring init and build in poly-bench-project. The Case Study: Python walks through a concrete example.

What's Involved

Adding a new runtime requires the following steps:

Implement the runtime spec — Runtime, RuntimeFactory, ErrorMapper, and RuntimePlugin from poly-bench-traits.
Register the plugin — Use #[distributed_slice(PLUGINS)] so poly-bench discovers it.
Add init and build support — Scaffold files in poly-bench-project (init, build, templates, deps).
Add LSP integration — VirtualFileBuilder, EmbeddedLspClient, and diagnostics (optional but recommended).
Write tests — Execution snapshot, LSP integration, and init runtime dirs.
