lackpy-lang
The lackpy language as a standalone, dependency-free distribution: the grammar (allowed/forbidden AST nodes, builtins, names), the validator, the grader, and the language spec. This is the pure-language leaf of lackpy — it has no runtime dependencies and pulls in none of lackpy's interpreters, policy layer, service, or MCP surface.
Why a separate package?
So consumers that only need to reason about lackpy programs — validate them, grade
them, or describe the language — can do so without installing lackpy's full runtime.
For example, a coaching/policy tool can classify a generated program against the
canonical grammar by importing lackpy.lang directly, instead of mirroring the
definitions by hand.
from lackpy.lang import validate, compute_grade, get_spec
result = validate("x = sorted(items)\nprint(x[0])")
assert result.valid
Namespace
lackpy-lang and lackpy share the lackpy namespace via
PEP 420 (implicit namespace packages): neither
ships a top-level lackpy/__init__.py. Installing lackpy pulls in lackpy-lang
automatically; installing lackpy-lang alone gives you exactly lackpy.lang.
Development (monorepo)
# editable install of both, from the lackpy repo root:
pip install -e ./packages/lackpy-lang -e .
