This release is a pre-release and may not be stable for production use.
tablambda
A pure lambda-calculus interpreter and compiler, realizing the semantics of the
paper paper/tablambda.tex and depending on fixpoints.
pip install tablambda
You write ordinary pure lambda terms, and the interpreter gives them powers a pure language normally lacks:
- Cyclic and infinite data structures, built and transformed directly, with no
letrec, no added recursion construct, and no mutable references. - Automatic memoization and dynamic programming: repeated subproblems are shared for you, with no cache written by hand.
- A diverging loop is detected and returns a meaningless value in finite time instead of hanging.
The companion compiler turns a term into a standalone Python module, so a program written once as a lambda term can also run as compiled code.
No parser is provided: terms are built directly in Python, with a small prelude of the usual combinators, Church numerals, and Scott-encoded lists.
