Language support for LisPython (.lpy) — a Lisp-like syntax for Python with Lisp-like macros.

Features

Syntax highlighting — full TextMate grammar covering special forms, operators, strings, f-strings, macros, and keywords
Bracket matching and rainbow parens (via VS Code's built-in bracket pair colorization)
Language server powered by lpy-lsp:
- Diagnostics — parse and compile errors reported inline
- Document outline — functions, classes, macros, variables, imports (Ctrl+Shift+O)
- Hover — documentation for all special forms, operators, and Python builtins
- Go to Definition (F12) — jumps to local, imported, and workspace-wide definitions
- Find All References (Shift+F12) — all occurrences of a symbol

Find References

Requirements

This extension requires the LisPython package to be installed in a Python environment:

pip install lispython

This installs the lpy-lsp language server used by this extension.

Setup

After opening a .lpy file for the first time:

Click the LisPy: ... indicator in the status bar (bottom right)
Select the Python interpreter that has lispython installed (auto-discovers system Python, workspace .venv, and parent venvs)

The LSP server will restart with the selected interpreter.

Commands

Command	Description
`LisPython: Select Python Interpreter`	Pick the Python interpreter for the LSP server
`LisPython: Restart Language Server`	Restart the LSP server after changing settings

Settings

Setting	Default	Description
`lispython.lsp.pythonPath`	`python3`	Path to the Python interpreter that has lispython installed

About LisPython

LisPython is a Lisp-like syntax layer for Python — 100% compatible with Python libraries, with Clojure-inspired macros (defmacro, quasiquote, unquote, splice).

(require lispy.macros *)

(def fib [n]
  (return (ife (< n 2)
               n
               (+ (fib (- n 1)) (fib (- n 2))))))

(defmacro when [condition *body]
  (return `(if ~condition (do ~@body))))
