sichercalc 0.0.0.dev1

A lightweight AST based expression evaluator

sichercalc

Fork of ast_calculator, modernized and refactored as a reusable library.

What is SicherCalc?

When you need to evaluate simple mathematical or logical expressions supplied by untrusted users, you need a sandboxed environment that prevents arbitrary code execution. SafeCalc parses the expression into an abstract syntax tree (AST), inspects each node, and evaluates only those that belong to a predefined, whitelisted set of operations.

Why AST?

An abstract syntax tree (AST) is a tree‑structured representation of source code. By operating on the AST we can precisely control which constructs are allowed, eliminating the security risks associated with eval().

Features

• No eval() – pure AST parsing and controlled evaluation
• Extensible – register your own custom functions
• Works on Python 3.10+
