Osprey for VS Code
Preview. Osprey is pre-production and evolving fast. Expect rough edges.
Language support for Osprey — a functional programming
language with algebraic effects, fiber-based concurrency, pattern matching, and
strong compile-time safety.
Powered by a Rust language server (osprey lsp, built on
lspkit) that runs the compiler front-end
in-process — the same engine targeted at Neovim and Zed next.
Features
- Syntax highlighting for
.osp files — keywords, types, string
interpolation ("Hello ${name}!"), operators, and comments.
- Live diagnostics — errors and warnings from the Osprey compiler as you
type, inline in the editor.
- Hover, go-to-definition, find-references, document symbols, signature help,
and completion — driven by the compiler's own parser and type checker.
- Compile & run from the editor:
Osprey: Compile Osprey File (Ctrl/Cmd+Shift+B)Osprey: Compile and Run Osprey File (F5)
- Bracket matching, auto-closing, and comment toggling.
Requirements
The extension bundles a version-matched Osprey compiler for your platform and
verifies it at startup, so syntax checking works out of the box.
To compile and run programs, Osprey invokes LLVM and a C toolchain, so install:
- LLVM (provides
llc) — brew install llvm / scoop install llvm
- A C compiler —
clang (macOS/Linux) or MinGW gcc (scoop install gcc)
Or install the full toolchain via a package manager (this also puts osprey on
your PATH):
brew install nimblesite/tap/osprey # macOS / Linux
scoop bucket add nimblesite https://github.com/Nimblesite/scoop-bucket && scoop install osprey # Windows
