Spork
Spork is a Lisp hosted on CPython. It compiles to Python AST, interoperates directly with Python libraries, and adds macros, expression-oriented forms, immutable persistent collections, source-mapped errors, and one project-aware CLI.
Spork is pre-1.0 and supports CPython 3.10–3.14.
Install
On Linux, macOS, or WSL, use the reviewed installer hosted with the documentation:
curl -fsSL https://spork.sh/install | sh
Or install the CLI with pipx:
pipx install spork-lang
Try it
Create hello.spork:
(defn greet [name]
(fmt "Hello, {}!" name))
(print (greet "Spork"))
Run it directly:
spork hello.spork
Create an isolated project when the program grows:
spork new hello-spork
cd hello-spork
spork sync
spork check
spork test
spork run
Narrow a test run by file, exact test, or name substring:
spork test tests/hello_spork/core_test.spork
spork test tests/hello_spork/core_test.spork::greet-works
spork test --filter greet
A project’s spork.it declares dependencies, source paths, an entry point, and a compatible spork-lang range. Project commands automatically use the compatible toolchain synchronized into .venv.
Documentation
The canonical documentation is maintained at spork.sh/docs:
- Getting started
- Language reference
- Standard library reference
- Project and CLI reference
- Editors and examples
Release changes remain in CHANGELOG.md. Repository-owned engineering notes remain under docs/; public documentation belongs on spork.sh.
Package boundaries
Compiled Spork distributions depend on spork-runtime rather than the compiler. Persistent collections are supplied by the standalone spork-pds extension.
Development
git clone https://github.com/spork-it/spork-lang.git
cd spork-lang
make venv
make test
Use make help for development, packaging, and cleanup targets.
