Mathematical expression evaluator

Mathematical expression evaluator fork with exports map, prototype pollution and code injection security fixes

A browser-based editor for the Expr expression language

Greffon runtime core: Expr, visitor/rewriter, partial evaluation, printer, WellKnown registry.

Patter reference runtime: load a bundle and play dialogue - flows, selectors, choices, jumps, effects, properties. Built on @wildwinter/expr + scoperegistry.

expr-eval alternative — redirects to a-calc, a modern precision math expression evaluator

Agnostic expression engine: parse, unparse, evaluate, and serialise a small condition/effect expression language. Scopes and built-in functions are injected via a Dialect.

TSLite codec — the data ↔ code boundary of a JSON value: data flattens, code becomes a #expr island (valueToJson/fromJson)

tiny util for getting and setting deep object props safely

DMN-style decision table over the @rfjs stack: rules are filter-builder condition trees, outputs are constants or data-expr "=" expressions, with first/collect hit policies

Arithmetic and function expression support for react-querybuilder

The Patter dialect for @wildwinter/expr (scopes shared/scene/flow, built-in functions), an ExpressionSchema builder from property declarations, and the inline {@ref} interpolation helpers (spec §16).

This plugin allows the [Jsonic](https://jsonic.senecajs.org) JSON parser to support expression syntax.
