DCL v0.9 Status: Experimental

Experimental

DCL Playground

Choose a validated example, edit the DCL source, and use the stable compiler adapter boundary that will host browser compilation.

Current language: DCL v0.9. Compiler: dcl 0.1.0.

The website is statically hosted on GitHub Pages. The compiler runs in your browser through Go WASM; no backend compile service is used.

Validated example Compiler 0.1.0

A minimal capability with one actor, one input shape, and one outcome.

Source: website/src/examples/hello-world.dcl

Editor help

Autocomplete: macOS Option+Escape, Windows/Linux Ctrl+Space, or the Show suggestions button. Format source with Shift+Option+F on macOS, Shift+Alt+F on Windows/Linux, or the Format button.

Browser compiler status

The Compile button calls compileDcl(source), which loads the static WASM compiler from /compiler/dcl.wasm. If the WASM runtime cannot load, the adapter reports that clearly in diagnostics.

Next extension points

  • Editor diagnostics and completion suggestions.
  • Compiler WASM loading behind the existing adapter.
  • IR view for compiler output.
  • Capability graph and lifecycle diagram views.
  • Policy and diagnostic explanations.
