sdev for Visual Studio Code
Official VS Code support for the sdev programming language — both tracks:
- v1 — the tree-walking interpreter (
forge, conjure, ponder, graphics, web, Leaflet)
- v2 — the self-hosted compiler (
say, set … to, to … with … end) running on the seed VM
Features
- 🎨 Syntax highlighting for
.sdev and .sdv — v1 and v2 keywords, lists, tomes, floats,
operators, classes, functions, blocks
- 🧬 Embedded JavaScript —
js { … } blocks are highlighted as real JavaScript
- 🔌 Hardware sketches —
board "uno" { … } blocks highlighted, with a ready-made snippet
- 🧠 ML / LLM stdlib highlighting — tensors, autograd, transformers, training, self-evolution,
plus the FFI / CUDA / WebGPU accelerators
- 🧩 34 snippets across both dialects
- ⚡ Run File —
Ctrl+Enter / Cmd+Enter (targets the dialect set in sdev.dialect)
- 🚀 Run with v2 —
Ctrl+Alt+Enter compiles with the self-hosted compiler and runs the bytecode
on the bundled seed VM (with read_file, write_file and http_get wired to the host)
- 🛠 Build Native Executable — emits x86-64 GNU assembly and links a static binary
- ✂️ Run selection —
Ctrl+Shift+Enter / Cmd+Shift+Enter
- 📦 Everything bundled — v1 JS interpreter, v1 Python interpreter, the v2 seed VM (
.wasm),
the self-hosted compiler driver and the native backend. Only Node.js is required.
- 🌐 Playground & docs commands

Quickstart
v1
forge message be "Hello, World!"
speak(message)
conjure greet(name) ::
yield "Hello, " + name + "!"
;;
speak(greet("sdev"))
v2
to fib with n
if n < 2
return n
end
return fib(n - 1) + fib(n - 2)
end
set scores to { "alice": 3, "bob": 5 }
for each name in keys(scores)
say concat(concat(name, " = "), str(scores[name]))
end
say fib(10)
Press Ctrl+Alt+Enter to compile and run it on the seed VM, or run
sdev: Build Native Executable to produce a static x86-64 binary.
Installation (manual / .vsix)
