Three-valued predicate and expression evaluation trees, stored as JSON and evaluated against injected resolvers, for domain logic — business rules, eligibility checks, formulas, search filters, and more — that needs to be data instead of code.

Functionality for working with trilean logic, which is logic involving three possible truth values

A documentation website for @zthun/trilean.

Compiles a trilean predicate tree into a parameterised SQL WHERE fragment, pushing three-valued logic down onto the database's own NULL propagation instead of evaluating it in process.

A portable regular-expression grammar -- a true regular language, with a Thompson-construction reference matcher -- so a pattern means the same thing in process and wherever trilean-sql can push it down to a database's own engine.

A tri state boolean logic type.
