S-expression parser, evaluator, and primitive registry in shared/sexp/. 109 unit tests covering parsing, evaluation, special forms, lambdas, closures, components (defcomp), and 60+ pure builtins. Test infrastructure: Dockerfile.unit (tier 1, fast) and Dockerfile.integration (tier 2, ffmpeg). Dev watch mode auto-reruns on file changes. Deploy gate blocks push on test failure.

S-expression language core.
|
|
|
|
Parse, evaluate, and serialize s-expressions. This package provides the
|
|
foundation for the composable fragment architecture described in
|
|
``docs/sexp-architecture-plan.md``.
|
|
|
|
Quick start::
|
|
|
|
from shared.sexp import parse, evaluate, serialize, Symbol, Keyword
|
|
|
|
expr = parse('(let ((x 10)) (+ x 1))')
|
|
result = evaluate(expr) # → 11
|
|
|
|
expr2 = parse('(map (fn (n) (* n n)) (list 1 2 3))')
|
|
result2 = evaluate(expr2) # → [1, 4, 9]
|
