stringwhether

Stringwhether is a term used in text processing and data querying to refer to the practice of expressing boolean conditions as plain text strings that can be parsed and evaluated against a collection of strings. It emphasizes human readability by allowing predicates to be written and stored as simple strings.

Definition and scope: Stringwhether is not a formal standard language, but a concept that describes how boolean filters can be authored as textual predicates. It sits between natural language interfaces and formal query languages, offering a readable form that can be converted into executable logic by a lightweight parser or evaluation engine.

Mechanics: A stringwhether engine tokenizes the predicate, supports operators such as and, or, not, and uses common comparison operators like =, !=, >, <. It may also recognize functions such as contains(substr) or length(). The engine then evaluates the predicate against each item in a dataset, returning those items that satisfy the condition. The approach foregrounds simplicity and flexibility, but relies on deterministic parsing rules to avoid ambiguity.

Examples and applications: Stringwhether can be used in search tools to express filters, in data-cleaning pipelines to apply rule-based transformations, or in natural-language interfaces that translate user input into textual predicates. For instance, a predicate like "length > 5 and contains 'weather'" selects strings longer than five characters that include the substring weather.

Relation to other concepts: Stringwhether relates to regular expressions, predicate logic, and query languages, sharing the goal of filtering data with concise, executable conditions while differing in emphasis on readability and ease of authoring.
